The quality of the power LED lamp beads is divided from these aspects: light effect, color temperature, color rendering index, light decay. Light efficiency: It is the main parameter of distinguishing LED lamp beads. At present, the mainstream single-year-old power white light LED light effect is 70-100LM/W. Color temperature: According to the color temperature difference, the year-old power LED lamp beads can be divided into warm white (2800K-3200K new ultra-bright LED lamp beads), natural white (4000K-4500K), Zhengbai (6000K--6500K). The smaller the color temperature grading, the better, so that when the amount of LED lamp beads lit all the way, the consistency errors of light due to the difference in color temperature are too old. The higher the color rendering index RA, of course, the better, so that it will not make the object color from the object. Generally, the display index RA can reach 80 and it is already very good. The light decay of power LED lamp beads is important. Sometimes the chip and fluorescent powder of some manufacturers will have an impact. The better the heat dissipation of LED lamp beads, the smaller the light decay, and the longer the available life span (when the light decay of the LED lamp beads is decayed by 30%, the LED lamp beads can be bright, but the light effect is very low, and the light effect is very low, and the light effect is very low. There is no practical significance of lighting). The power LED lamp bead must be installed on the heat dissipation device, otherwise it will be serious due to the high temperature due to high temperature. If we lit a 1W power LED lamp bead directly, the temperature of the copper pillar at the bottom of the bottom after an hour can reach 110 C. When the lamp beads are used, it is necessary to add a heat dissipation device. This is also a major problem for LED lamp bead lighting. --- The article comes from LED lamp beads, please indicate Tongjia (China) www.tongjialed.com
