Looking for the development of light source in LED light source

Introduction: LED lighting industry booming, LED lighting new technology emerging. But LED lighting into the footsteps of the civilian population home is always difficult to stride.

"Innovation" is to explore the issue of all walks of life, recently, LED lighting industry has also set off a "new technology and new products" in the name of the industry meeting wind, similar to such activities, I also participated in several meetings, for these activities issued by the "new technology and new products, to today LED lighting development concluded 3 points: the volume is more and more small, more and more functions, technology is more and more strong. If the LED lamp anatomy, we can know that the lighting design is based on the LED light-emitting part, the control part and the optical structure design of the three party game.

Looking for the development of light source in LED light source

The development of LED lighting industry is booming, LED lighting new technologies emerge in an endless stream. But LED lighting into the footsteps of the civilian population home is always difficult to stride. Innovative LED lamp package technology, the LED light effect every month has improved, LED bulb prices continue to decline, high voltage LED technology matures, reduce the heat to become a reality LED lamp cavity. COB integrated light source is widely used in the LED bulb, LED lamp, LED lamp, LED lamp, LED ceiling lamps, LED bean lamp products, is one of the main trend of LED lighting at present. For COB, the COB packaging thermal channel is shorter, smaller thermal resistance. Due to the high power integration, the need to consider the chip itself and the waveguide effect caused by the decline in the efficiency of the problem, the chip structure is the key to improve the efficiency of the droop. COB solve the traditional discrete LED light source can not solve those problems in lighting applications, because COB uses integral light mixing process, the light emitting angle is larger, the two optical design is relatively easy, reduce the incident to the human eye luminosity, so COB flexible surface light source is the inevitable trend of indoor lighting.

High efficiency, no stroboscopic technology development trend

Improve the power conversion efficiency, can reduce the whole lamp power, is to improve the overall lighting efficiency, save the heat dissipation design costs. Power factor requirements before the switching power supply no regulatory requirements, but LED lighting countries have a hard target. Reliability, life expectancy is also an important part of the current. There are also aspects of color temperature, brightness, intelligence is also the future needs. LED lighting driving experience (1), isolated AC/DC: high cost, large volume, multiple devices, electrolytic capacitor is easily broken; (2) high voltage linear non isolated low PF value, low efficiency, can't adapt to ERP and energy star, small volume, lower performance, volume reduction to the limit; (3) high order piecewise intelligent dimming: high PF value, high efficiency, no stroboscopic, full voltage intelligent dimming, meet the ERP directive, standard energy star; in this view, the development trend of LED lighting drive is no drive, photoelectric integration. Cancel the power supply can not understand the driving is not required, but not the "electricity", but do not hinder the life of the device to cancel part of power supply, a new LED drive mode, but also in recent years in the LED lighting industry caused by hot new technology.
