The Difference Between Integrated Light Source LED

Very practical LED lamp bead light source, LED integrated light source surface damage or cracking causes the light source to be unable to light up and the dead lamp is adverse. W, more than 70LM/W and 100LM/W of T5 lamps with ordinary fluorescent lamps, making the overall light effect of LED light boxes higher. LED transient light effect refers to the lighting efficiency of the LED light source when starting to work, also known as the initial cold -state light effect. It is the instantaneous optical flux measured by a certain short pulse current by the metering source. The heating time constant of the substrate, the width of the heating pulse is usually 1- tens of ms. Integrated light sources LED hardening or light sources caused by welding or use, the golden thread is broken during the thermal expansion and contraction of the colloid, which causes dead lights; in addition, the LED light source is a solid -state light source. This means more stable. In addition, the service life of high -pressure sodium lamps and gold halide lamps is usually less than 6000 hours, and the color rendering index is less than 30; LED has significant advantages such as high efficiency, energy saving, long life (50,000 hours), environmental protection, high color rendering index (> 75), etc. How to effectively apply LEDs on road lighting has become the most popular topic of LED and street light manufacturers. As the core of LED street lights, the manufacturing technology of LED chips and the corresponding packaging technology jointly determine the application prospects of LED in the field of lighting in the future. The main reason for the large failure failure is the yellowing or reduction of silicone or reduction. The formal LED P and N electrodes are on the same side of the LED. The current must flow across the N-GAN layer horizontally, resulting in a crowded current, high local heat, and limiting the driving current. Disappear. In the process of long -term use, the high temperature caused by poor heat dissipation affects the performance and transmission of silicone, which causes a large light output power attenuation. Integrated light source LED not only has fast booting speed, but also has more angles when using it. There is no pressure on projection, sideways, and oblique projection. Due to the complex process process, the process of the process cannot be repaired. The inverted process application process is simple, and the bad light can be repaired. Compared with the formal packaging process, the packaging density of the inverted process has increased by 16 times. Integrated packaging is also called polycrystalline packaging. The number of LED chips on the substrate base based on the required power is determined. 3W high -brightness high -power LED devices. Finally, the chip is encapsulated to the chip with a high refractive index material according to the shape of the optical design. Cob package“COB light source module→LED lamps”, Can be directly encapsulated by multiple chips on MCPCB on the metal -based printing circuit board, and directly dissipate the heat through the substrate to save LED packaging costs, light engine module production costs, and secondary lighting costs. In terms of performance, through reasonable design and microscopy, the COB light source module can effectively avoid the disadvantages of light and glare exist in the combination of separation light source devices; it can also effectively improve the color of the light source by adding appropriate red chip combinations sex. Integrated light source LED packaging volume has been reduced by 80%, the light color distribution is more uniform, and the cost is lower, but smaller chips are bound to put forward very high technical requirements for equipment accuracy and solid crystal tinnodium paste.
