Opportunities and Challenges Facing the Trend of Intelligent LED Technology

　LED lighting with energy-saving, environmental protection, longevity, earthquake, small, fast response and so on. Currently, LED applications include backlighting, general lighting and automotive lighting of the three markets. With LED lights prices, comfort and safety become technical direction of the semiconductor lighting. In addition, the semiconductor lighting era of intelligent lighting will open. Intelligent lighting with light brightness adjustment, color temperature adjustment, light soft-start, timing control, scene settings and other functions, and to achieve a personalized, comfortable, secondary energy saving, safe and efficient requirements.

　LED lighting has many outstanding advantages: energy - DC drive, electro-optical power conversion close to 100%, the same lighting effects than traditional energy sources more than 80%; long life - life of up to 60,000 to 100,000 hours, compared to traditional light sources long life more than 10 times; more color variation - red, green, and blue color theory, under the control of computer technology to make three colors with 256 gray scale, and any mix can produce 256 -- 256 -- 256-16777216 colors; environmental protection - neither heat nor radiation, glare is small, recyclable, no mercury elements, cold light source, safe touch; high - low voltage microelectronic products, the integration of computer technology, network communications technology, image processing technology embedded control technology, semiconductor optoelectronic devices digital information products, with online programming, unlimited scalability, flexible features.

　 LED lighting is relatively higher than the price of conventional light sources, which became one of the barriers to enter the LED market. In addition, excess capacity has also led to fierce competition in the LED market. Promote the development of LED lighting market is a key driver with high brightness LED and smart LED controller. High brightness LED product designers face many design challenges, including thermal management, driver program, topology architecture and infrastructure.

Led Lights Need To Have The Six Elements

LED display screen, and LED electronic display screen more appear in people's field of vision, LED lighting has also been some of the main streets with LED lights, LED lights need to have what conditions?

One , energy-saving with low voltage small current high brightness characteristics. As the LED lamp using the LED lamp must have low voltage, current, high brightness characteristics, it is ensure that the installation time to normal use, high efficiency and   energy saving.

Two, the new green light, using LED cold light glare small no radiation use do not emit harmful substances. LED environmental protection benefit are better, no ultraviolet and infrared spectrum, and recyclable waste, it does not contain the mercury element has no pollution safe touch, typical of green lighting source.

Three, long life. LED road lamp due to the continuous use, replacing time is also required for volume replacement is more trouble, so in the choice of when, long life is also an important factor, Ohmax light significant production of LED lighting basic service life in more than 50000 hour, in full compliance with the conditions.

Four, lamp has reasonable structure. LED lamp will completely change the structure of the lamp, according to different application requirements, LED lamp structure to raise the initial brightness conditions through rare earth again, increase the brightness, after the optical lens to improve the brightness of light, be improved. LED is encapsulated by epoxy resin solid light source, its structure has no glass bulb filament easily damaged parts, it is a full solid structure, so it can withstand the shocks, without being damaged.

Five, colour pure color, multiple. As a street lamp using the LED street lamp must light only, it do not need too much noise, in ensuring the brightness of the lighting also needed to ensure road safety.

Six, high security. LED light source using low driving voltage, light stability, no pollution, no using 50Hz AC power supply when the stroboscopic phenomenon, no ultraviolet B radiation, color rendering index Ra is close to one thousand, color temperature, color temperature fifty five K five thousand K, closest to the sun. Is the calorific value of low no thermal radiation cold light source and can accurately control the light and emitting angle, light color and soft, no glare; and do not contain mercury and sodium elements may harm LED road material.
