The Difference Between Integrated Lamp Beads

When it comes to the LED lamp bead light source, the LED light cast light is controlled by the built -in micro chip. In the application of small engineering, it can be used without controller, which can achieve gradient, jumping, color flashing, random flashing, chip packaging forms in the form of packaging in the chip. There are many types, COB is just one of them. Although the COB (Chip On Board) literal translation seems to be the chip installed on the board. But from the history of COB,“Chip on Board”middle“Board”It didn't mean a casual one at the beginning“plate”Instead, it refers to the printed circuit board (PCB). In the packaging of semiconductor devices, many of them are fixed on a substrate and packaged, but they are not called COB packaging. Therefore, the COB encapsulated substrate (BOARD) does not refer to a casual board. 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. The dynamic effects of integrated lamp beads alternately alternately can also achieve the effect of chasing, scanning through the control of DMX. At present, these main application places are probably these: single buildings, historical building group exterior wall lighting, light and outer transparency in the building, indoor local lighting, green landscape lighting, advertising card lighting, and above are LED projection light sources. In fact, projection is actually projected. The machine also has light bulb light sources (ultra -high -pressure mercury lamps and pyrine lamps) and laser light sources. The light sources of light bulbs are traditional light sources. LED light sources and laser light sources are new light sources. Due to the huge market potential in the integrated lamp beads, the application of LED -related industries is rapidly expanding from general lighting to almost all fields. Different from general lighting, the lighting applications of some special fields have also received more and more attention, and the market prospects are becoming more and more optimistic. These applications need to rely on the special LED light source. From the perspective of the packaging process, there are many sizes used by the COB light source. Its shapes are dozens of stents with different sizes such as square, rectangular, ellipse. Smedie, generally do not bring the feet. The brackets used in integrated LED lamp beads are only 10W, 100W, 500W and other square brackets. The materials are mainly copper, and the brackets have 2 side feet. When choosing outdoor lighting in construction engineering or garden projects, LED shots will be selected. Such a light lamp has a certain advantage in itself. Regarding these free -driven LED light sources, the LED pan -light light is a dot source that can be evenly illuminated in all directions. Its irradiation range can be adjusted arbitrarily. In order to obtain a good current expansion, the NI-AU metal electrode layer cannot be too thin. For this reason, the lighting efficiency of the device will be greatly affected. Usually, both factors: both current expansion and outlet efficiency. But under what circumstances, the existence of a metal film will always make the light transmission performance worse. In addition, the existence of the leading welding joint also affects the light efficiency of the device. The structure of the Ganled inverted chip can fundamentally eliminate the above problems above. In the future, the market will develop in the direction of professionalism. From the optical perspective, CSP is more suitable for trap and not suitable for shooting lights. EMC & PCT is more suitable for small and medium -sized power products with high cost performance. Ceramic packaging is suitable for small -sized high -power products. Even if the CSP technology is more mature, after all, it is impossible to reduce the size in size, and there will still be bottlenecks. The survival market of the packaging manufacturer is still very considerable. Integrated light beads pan -light is the most widely used light source in renderings. Standard pan -light lights are used to illuminate the entire scene. You can use multiple pan -light lights in the scene to produce better results.
