The Advantages of Blu -ray Cob Lamp Bead

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 adverse cause analysis: LED light source use temperature reaches the limit to the limit cause of the colloidal loss to achieve high power LED lighting The single -power LED chip is encapsulated, and the second is to use multi -chip integration packaging. For the former, with the development of chip technology, the size increases and the quality is improved, high -power LEDs can be achieved through large current drivers, but at the same time, it will be limited by chip size. The latter has greater flexibility and development potential. The number of chips can be changed according to different illuminations. At the same time, it has a high cost performance, making LED integration packaging into one of the mainstream directions for LED packaging. The steady -state light effect refers to the ratio of the light flux measurement to the electrical power measured when the chip knot temperature is no longer rising and the light strong when the light is strong when the LED light source work enters the thermal stability. The steady -state light effect refers to the optical effects of LED overall lamps except to drive the power supply, which reflects the comprehensive characteristics of light, electricity, and thermal in the actual work of LED. In addition to LED transient light and electrical specialty, the steady -state light effect also includes the temperature changes of system heat transmission and heat dissipation. It is also known as system light. Blu -ray COB lamp beads hardening or light sources caused by welding or use. During the collagen, the golden thread is broken during the thermal expansion and contraction of the colloid. In addition, what is the LED light source? Friends who are unfamiliar with this question often ask for friends who are familiar with the projector. Compared to traditional light sources, the volume of LED light sources is smaller. Therefore, there are many small smart projection in the market now. 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. From the analysis of the number of chips and the integrated density of the chip, it is found that the integrated packaging multi -chip white LED knot temperature increases with the increase of the number of integrated chips. The emotional efficiency has decreased with the increase of the number of integrated chips. Therefore The quantity and integrated density are also an important influencing factor in the application of integrated packaging technology. Blu -ray COB lamp beads are actually because of the LED light source. Therefore, there can be such a volume advantage. The traditional light bulb light source requires larger space to dissipate heat. From encapsulation to assembly, the LED formation process requires six processes (solid crystals, welded wires, packaging, corner cutting slices, spare time, packaging). The unique packaging principle determines that it has many advantages, such as: (1) the research and development of high -power chips in my country is in a backward position. The use of integrated packaging is a shortcut for development, which is more in line with my country's basic national conditions; (2 2 ) The chip can be designed as a series or parallel, which flexibly adapts to different voltage and current, facilitates the design of the drive, and improves the light effect and reliability of the light source;. The transient light effect is the light -time light of LED light source_Co -electric conversion characteristics. It is related to the chip and fluorescent powder quantum quantum stimulation capacity, colloid refractive index, light transmission rate, bracket structure (reflector cup) reflector and other conditions. Basically irrelevant. It only measures the comparison meaning, and the transient light effect cannot represent the actual working state. Blu -ray COB lamp lamp filter, chip machine, spectrochemore, editing machine) and six major materials (chips, brackets, insulation gels, gold threads, silicone, fluorescent powder) need a lot of labor and many costs. And because of structural problems, the encapsulated lamp beads cannot shine at 180 degrees, and the lighting effect is affected.
