(A): the pursuit of the illumination brightness is easy to produce light pollution:

Long-term commitment to the green low-carbon lighting design either see that the generation of artificial light in order to improve the function of life, to achieve high efficiency, bright city, bright family life. However, with the rapid development of lighting technology, design techniques, especially after the use of LED lighting research and development to improve quality of life-centered orientation, a change in today\\ s lighting has entered the era of high brightness.

If the sense of light, modern and scientific and technological sense is the pursuit of the effect of lighting, so \"bright\" behind filled with a lot of doubt, was accused of \"social evil\" energy waste, they can not evade the facts.

In this regard, he served as the cited flexible run out of a classic case – Tokyo Ginza Chanel lighting design:

The Ginza is Japan\\ s most popular shopping areas, its light engineering remarkable. Neon depths of a \"are all bright, I alone dark\" buildings, Chanel Tokyo flagship store. The lighting design to abandon the bright colors of the LED, using only black and white two colors, the night, the LED will be to create a classic Chanel totem. In the eyes of tourists, the Ginza is very bright, but the building is very dark; other building is a dynamic flashy, the building is gentle classic.

Once people grasp and free to use the LED light source, buildings, business district, landscape, bridges and other lighting applications, a large number of lamps to increase light brightness, the use of dynamic, colored lighting to render the atmosphere of light, not knowing that almost all the space have become the shade of unbridled use of spaces. People\\ s living environment of the experimental field of light, is indeed a \"dangerous\" things!

(B): Do not destroy the illuminated original art styling

Lighting project, designers and construction side, while taking into account the lighting effects, taking into account the shape and connotation of the building itself is a difficulty.

The night lighting is a culture, it is art. Care of historical and cultural landscape original style and architectural art features, night lighting is extremely important design concepts, but also environmental protection an important part of the landscape.

Night lighting should be hidden settings, especially large public buildings, ancient buildings, antique buildings and European architecture, the night view of the roof or dome landscaping, put an end to the destruction of the classical architecture of the plastic arts. Lighting, landscaping, during the day and night to \"see the light but not light. However, the current landscape of the country there are quite a lot of famous buildings exposed lamp lights with the destruction of the visual impact.

Including lots of billboards and light boxes in Commercial Street, residential buildings, public squares, etc., in case there are no standard constraints, the light boxes are free to install lights intertwined, even light boxes stacked light box, the appearance of many buildings are varying degrees of occlusion and impede the appearance of the building, also affected the building within sight.

Serious scientific research on lighting or non-standard lighting, LED or other new lighting technologies, research and care of landscape original historical and artistic characteristics of the way.

(C): used with caution in high energy-consuming strong glare of the lamps

Says \"With the widespread dissemination of low carbon environmental protection concept, the use of long life, high luminous efficiency, high-quality energy-saving light source is the purpose of our design.\" Talking about the design philosophy for many years insisted, Zhimei lighting design company chief designer of any see.

Most of the urban landscape lighting using LED, metal halide lamps, high pressure sodium, color, high pressure sodium lamps, these light and incandescent light than the prominent features of the up-efficient, long life, the inadequacies of the annex more, one-time The investment is large.

Our country should not be lower than the relevant specifications of the lighting illumination lamps installed in the outdoor enclosure protection class IP54; buried lamps Protection class of enclosure should not be less than IP67. Should be used in strict accordance with the relevant parameters, select the lamp at the same time, to meet the glare limit and light distribution requirements under the conditions of high efficiency lamps. Floodlights lighting efficiency should not be less than 65%.

Of course, under the premise of the energy-efficient, the lighting effects of the final integrated programs should be firmly in the designer in the hands.

Popular in recent years the size of the lighting project in China LED light source, who is now the first choice of the vast majority of the lighting profession. LED products Needless to say, however, any lighting project, priority LED products, which has become the beginning of the bottleneck of many designers career. There are a lot of designers like zoned for the prison, thinking that LED is designed for the \"shiny\" and \"brilliance\" and \"technology\" is born. In fact, the only designer to master the use of appliances, lighting design is to achieve development by leaps and bounds.

Characteristics of the semiconductor light-emitting diode (LED) because of its small size, directional emission of light, high brightness, the PN junction electrical characteristics, so many new problems in quality evaluation and testing methods. Different applications, determines the performance requirements of LED products. From the optical properties of LEDs for display brightness, viewing angle, color and other parameters. LED for general lighting, pay more attention to the luminous flux, spatial distribution of the beam, the parameters of color, the color rendering properties, and biological applications of LED, it is even more concerned about the parameters of the biological effective radiated power, the effective irradiance. In addition, the light-emitting diode is both a light source, but also a power-type semiconductor devices, about its quality must be a comprehensive evaluation of many aspects of optical, electrical and thermal.

LED lighting products from the point of view of the structure and the industrial development of LED products currently mainly need to consider several parameters of the optical properties, electrical properties, thermal properties, radiation safety and life.

Optical properties: the LED optical properties are mainly related to the performance requirements of the spectrum, brightness, and chroma. According to new industry standards set by the semiconductor light-emitting diode test method \", the main luminescence peak wavelength, spectral radiation bandwidth, axial luminous intensity, the beam angle of half intensity, luminous flux, radiant flux, luminous efficiency, chromaticity coordinates, color temperature, color purity and dominant wavelength and color rendering index and other parameters. The LED display with visual visual effects, correlated color temperature and color rendering index is not required, and the white LED lighting, these two parameters is particularly important, it is an important indicator of lighting atmosphere and the effect, while the color The purity and dominant wavelength is generally not required.

Electrical properties: the LED PN junction electrical characteristics, determines the electrical properties different from the traditional light source, LED lighting applications, one-way non-linear electrical properties, low-voltage drive, as well as static-sensitive features. The main measurement parameters include the forward drive current, forward voltage drop and reverse leakage current, reverse breakdown voltage and electrostatic sensitivity.

Thermal performance: lighting with LED luminous efficiency and power to improve one of the key issues in the development of LED industry, at the same time, LED PN junction temperature and shell heat issues is particularly important, generally with thermal resistance, case temperature, said junction temperature and other parameters.

Radiation safety: the International Electrotechnical Commission IEC LED products is equivalent to the requirements of the semiconductor laser radiation safety testing and demonstration. LED narrow beam, high-brightness light-emitting device, taking into account the radiation may harm the human eye retina for different occasions, the application of LED, the International Standard specifies the limits of its effective radiation requirements and test methods. Radiation safety in the European Union and the United States, LED lighting products as a mandatory safety requirement implementation.

Reliability and life: reliability index is a measure of the ability of the normal work of the LED in various environments. Particularly important in the LCD backlight and large screen display. Life is a cycle indicator of quality evaluation of LED products available, usually the useful life or ending life. In lighting applications, the useful life to the LED at rated power conditions, the flux decay to the duration of specified percentage of the initial value.

LED industry need to pay attention to the development of measurement standards

LED light-emitting surface is small, narrow beam, high brightness determine the characteristics of the particularity of its detection, in order to deal with this problem, the CIE TC2-45LED measurement \"and\" TC2-46CIE/ISOLED strength a measure of the two technical committees were set up . CIETC2-34 group meeting in Vienna, headquarters in October 1997, develop and recommend CIE127-1997LED measurement standards, it involves LED radiometric, photometric and colorimetric measurement. However, due to the rapid development in recent years, LED technology, the white LED lighting products, many of the problems the past are not taken into account. Therefore, the CIE at the annual meeting held in Kyoto, Japan in 1999, proposed by the participants on behalf of the developed countries, the development of white LED lighting equipment standards by CIETC2-34, the Japanese delegation also submitted two draft standards of general lighting with white LED.

In order to develop LED lighting technology, developed countries have attached great importance to the LED test methods and standards. Organizations such as the American National Standards the detection Institute (NIST), an internationally renowned testing experts to carry out the LED test, focus on the LED light emitting characteristics, temperature characteristics and lumen characteristics, test methods, trying to establish the full set of LED test methods and technical standards in the LED test has been walking in the forefront of the world. Japan set up a \"white LED Test Research Council, specializing in lighting white LED test methods and technical standards. Developed countries in the world in order to seize the high ground of the LED research, the LED standards and testing have invested a lot of manpower and resources, the standards focus on select parameters and testing methods of the characteristics of LED.

Thank you for inquiry my energy saving light bulbs, TEL:+86-571-64160007, E-MAIL:sales@udeman.net
http://www.udeman.net/lamps-energy-saving-lamps/

  The scientific name of the energy-saving lamp compact tricolor electronic fluorescent lamps (CFL lamp), by foreign manufacturers in 1978 invented the first, because of its high luminous efficiency (which is five times that of ordinary light bulbs), significant energy savings, long life (ordinary 8 times that of the lamp), small size, easy to use and other advantages, valued and welcomed by the peoples and countries, China in 1982, first successfully developed in the Fudan University Institute of Electric Light Source SL-type compact fluorescent lamp, the past two decades, the output rapid growth, the quality has improved steadily and have it as a national focus on the development of energy-saving products (green lighting) as the promotion and use.
The working principle of the energy-saving lamp through the ballast to the lamp filament heating to about 1160K, the filament to emit electrons (because some electronic powder coating on the filament) electron impact argon atom inelastic collision, argon atoms after the collision energy and impact of mercury atoms and mercury atoms absorb energy transitions produce ionizing issued 253.7nm UV, ultraviolet excitation light-emitting phosphors, fluorescent work, the temperature of the filament than incandescent temperature of about 1160K, 2200K -2700K is much lower, so its life expectancy improved, reaching more than 5000 hours, because it does not exist, as current incandescent thermal effects of the energy conversion efficiency of the phosphor is also high, reaching more than 60 lumens per watt.

Ordinary incandescent light efficiency about 10 lumens per watt, life is about 2000 hours or so, it works: When the lamp access circuit, current flows through the filament, the heating effect of current incandescent light issued by the continuous visible and infrared, this The phenomenon can be aware of the filament temperature to rise to 700K, due to the high filament temperature in the work, most of the energy wasted in the form of infrared radiation.

Energy-saving lamps in addition to white light, yellow (warm light) light. In general, under the same wattage, an energy-saving lamps than incandescent energy saving of 80%, the average life expectancy of 6-8 times the thermal radiation only 20%. Non-strict case, a 5-watt energy-saving light photos can be deemed to be equal to 25 watt incandescent bulb, 7 watt energy-saving lighting according to approximately equal to 40 watts, 9 watts equivalent to about 60 watts.

Quite a long period of time, in some places and blind manufacturers big energy-saving lamps on the project, due to not fully implemented in the capital, technology, raw materials and processes, making the product quality can not be guaranteed the quality of products the imbalance, and some manufacturers do not follow the process requirements, selection of non-conforming lamps and components for the assembly plant patchwork composition, quality lowest seriously damaged the reputation of the energy-saving lamps, light efficiency is low, life is short, consistency, a society in which the argument of the energy-saving lamp energy saving section is not money, a lot of negative impact to the promotion of energy-saving lamps.

(1) protect the LED circuit fuse (tube)

Since the fuse is a one-time, and the reaction is slow and poor results, the use of trouble, so the fuse is not suitable for the finished LED lights, LED light is now primarily in the glory of the city engineering and lighting engineering. It requires very harsh: can start immediately to protect beyond the normal use of current LED protection circuit, LED power supply path is disconnected, the LED and power supply can be protected, normal throughout the light and then be able to automatically recover for electricity, does not affect the LED. The circuit can not be too complicated and can not be too much volume, the cost is even lower. So the fuse is very difficult to implement.

(2) the use of transient voltage suppression diode (referred to as TVS)

Transient voltage suppression diode is a two-pole form of high-performance protection devices. When its poles by the reverse transient high-energy impact, the negative 12 power of 10 seconds of a very short time speed, so that between the poles of the high impedance immediately reduced to the low resistance to absorb up to several kilowatts power surge between the poles of the voltage clamp at a predetermined voltage value, the effective protection of the precision components in electronic circuits. Transient voltage suppression diode has a fast response time, the transient power, low leakage current, breakdown voltage deviation of consistency, the clamp voltage is easier to control, no damage to the limit, small size, etc..
But in actual use to find very easy to meet the requirements of the voltage value of the TVS device. Damage to the LED light source is caused because the current ambassador chip internal overheating. TVS can only detect over-voltage can not detect over-current. Please select the appropriate voltage protection point difficult to grasp, this device will not be able to produce it would be difficult in practice.

3 Select the resettable fuse

Resettable fuse, also known as polymer positive temperature thermistor PTC, is constitute by the polymer and conductive particles. After special processing, The conductive particles in the polymer chain conductive path. When the normal operating current through (or components in a normal ambient temperature), PTC resettable fuse was the low resistance state; when the circuit when the abnormal over-current through (or environmental temperature), high current (or environmental temperature) heat generated by the rapid expansion of the polymer, also cut off the conductive path constituted by the conductive particles, PTC resettable fuse high-impedance state; When the over-current circuit (over-temperature state) after the disappearance of the polymer cooling, the volume recovery normal conductive particles to re-constitute a conductive path, PTC resettable fuse was the initial low resistance state. Since the resumption of normal operation small Fuse fever, abnormal working status of its high heating resistance limits the current through it, which plays a protective role. In a specific circuit, you can choose:

 ① shunt protection. LED lights generally divided into many cascaded slip. We can be in front of each branch and a PTC element to protect. The benefits of this approach is the high accuracy and the reliability of protection.

The general principles

, according to the LED current and voltage characteristics, the ideal is to use a constant current driver. It can avoid the change of the LED forward voltage caused by the current changes at the same time a constant current LED brightness and stability.

b In addition, the LED luminous flux and inversely proportional to temperature, so the use should be to minimize the power of fever and a well-designed cooling system. Thereby reducing the temperature of the LED work.

c, in order to ensure that the overall life of the LED to the LED thermostat control within a certain range.

1 high reliability

LED products have the composition of the LED chip and power supply, cooling enclosure, the control circuit and so on. LED power supply have a direct impact the quality of products. LED street light product, installed in the high-altitude, maintenance inconvenience, the cost of maintenance.

2 high efficiency

LED energy-saving products, power supply should comply with the requirements of energy-efficient. Especially the structure of power supply installed in the fixture, is particularly important. LED luminous efficiency of LED temperature decreases. High efficiency power supply, the loss power, heat lamps, and reduces the temperature rise of the lamps. Can delay the LED light decline favorable.

3 constant current drive mode

To tie in with the VI characteristics of LED, LED power supply must be used the way of the constant current driver.

4 Surge Protection

LED impact resistance is relatively poor, so to enhance this protection. Especially in outdoor products, due to start and mine grid load. LED driver power supply have to inhibit the intrusion of the surge, the ability to protect the LED is not damaged.

5 temperature protection function

Power in addition to conventional protection functions, the best increase in the constant current output LED chip temperature negative feedback to prevent the LED chip PN section temperature is too high.

6 LED power supply life

The life of the drive power to make best efforts to match the life of the LED chip and.

7 work environment

As the various parts of the environment to focus on to consider LED lighting in the workplace environment, such as: temperature, humidity, and installation location.

Taking into account the work of the power, if not the soft-start circuitry, power moment, the output will be a voltage spike. For better protection LED, so it is necessary to add the soft-start circuit. This is what the drive power stability, a key factor.
