LED light word light source selection

It is noteworthy that, in the use of LED light-emitting module in the process, we must pay attention to the problem of voltage drop. Do not only do a loop, from the first series to the end. Doing so will not only between the end of the voltage difference between the resulting brightness is inconsistent, but also produce single-circuit current is too large to burn the circuit board problem. The correct approach is to connect as many circuits as possible to ensure that the voltage and current distribution is reasonable. In addition, the word cavity for the use of anti-corrosion material inside, preferably with a white primer to increase the reflection coefficient.

LED in the ultra-thin signs in the application of ultra-thin luminous signs is to improve business utilization on the basis of the place came into being. The past ultra-thin light-emitting signs and ultra-thin light-emitting light boxes in the thickness of roughly between 1.5-3.0cm. In 2004, the company Secretary on this basis, the independent development of a thickness of 0.8-1.5 cm between the ultra-thin signs. The product uses a light guide, injection molding, sculpture, backlight and other technologies. Characterized by the surface smooth, no engraved concave and convex marks, uniform light-free string light. Layout can be infinite bigger, small to the Department of licensing, to achieve the highway signs instructions can be produced. Such ultra-thin plate in the choice of LED, according to customer requirements and the size of the thickness of the layout to choose. Thickness of 8mm-10mm, area of ​​500cm2-400cm2 between the ultra-thin luminous signs, pixel tube light-emitting module can be used in the light-emitting module; ; Thickness of 10mm or more large ultra-thin light-emitting signs should be used in the luminous angle of 30 degrees within the ultra-bright light-emitting module.

In short, the majority of the advertising industry colleagues in the use of LED application technology products, in addition to considering the stability of LED, but also according to the requirements of the product to determine the LED light angle, brightness and tube between the wavelength is allowed . Only a reasonable choice of different specifications of the LED, in order to ensure product quality standards, while the cost is generated to a minimum. Scene of the LED lighting system and its overall characteristics of energy conservation and environmental protection is the common concern of all countries in the world social problems, and a direct impact on the sustainable development of human society. Direct consumption of energy on the lighting industry, more hope to achieve energy-saving green lighting. Semiconductor green light source of the birth of the revolution known as the field of lighting, its logo is a semiconductor light-emitting diode (LED) as a new light source from the special lighting market gradually into the general lighting market, the market prospect is extremely broad. As a special lighting source applications, white LED has shown a huge performance advantage, strong momentum and the rapid growth of market demand. In the next five years, LED lights are likely to become the mainstream of next-generation lighting products.

Light-emitting diode light bulbs in terms of structure or in the light principle, with the traditional white flag lights are essentially different. For a long time, people do not have the light-emitting diodes for lighting, mainly because the one hand, light emitting diode does not achieve red, green, blue three primary colors, can not achieve white light; the other is luminous intensity and luminous efficiency Claim. Now this troubled people's problems have finally been resolved. People use ultra-high brightness blue LED as the basis, using a variety of ways to achieve the white light. Has developed a light-emitting diode can be made white light bulb and the sun is very close, has good application prospects. For this reason, light-emitting diode light bulb will stand out from the traditional electronic equipment, become a star in the field of lighting, leading to a new lighting revolution. Semiconductor ultra-high brightness light-emitting diode (LED), especially nitride white light-emitting diodes, with a small size, low voltage, long life, fast response, no strobe, less energy consumption, less heat advantages, is gradually becoming a new generation of green , Energy saving, environmental protection, long-life lighting source.

White LED as a semiconductor light source, compared to traditional lighting, the power consumption is only about 20% of the latter. Life of up to 10 million hours, is the ordinary lamp several times. It has good reliability and low maintenance cost. The use of low voltage, the operating voltage is generally below 5V, in addition to portable LCD backlight machine, you can also use language outdoor lighting, remote mountain lighting, miners and water and environmental lighting. Switching time is short, the response time of up to 1 microsecond, the general lighting for a few milliseconds (the current light response time of 200 milliseconds). Environmental protection, no mercury and other hazardous waste, not easy to break strong, reduce waste on the environment pollution. LED lights do not contain infrared and ultraviolet components, there is no radiation pollution, and DC-driven, no strobe, is to protect the eyesight of environmental protection light source. With the widespread use of LED and performance improvement, a new lighting revolution is coming has become the consensus, then this change will look forward to bring what people: This is the development of LED applications and guide the development of the market is most concerned about The problem.
