0603 Patching LED Lighting Delite the Reason for the Decay of Light Decay!

In the LED industry, when you buy LED, you will test the problem of light decay. Today, I will explain to you what are the reasons for the decay at the decay of 0603LED lamp beads? 060LED lamp beads light decay is an irreversible brightness attenuation phenomenon caused by the damage of the light source material. 0603LED lamp beads refer to the LED lamp beads after a period of light. It is the light decay of 0603 patch LED lamp beads. At present, my country has not yet developed 0603 patch LED lamp beads light decaying Huai Huai, and the industry's internal rules of 50,000 hours of light flux maintenance rate is more than 70 %. Light flux landing does not equal light failure 0603 Patch LED lamp beads after working, its light will fall as the chip has a different temperature, and the light effect will decrease. This is the inherent physical characteristics of semiconductor with temperature changes. An part of the component of the pearl light is damaged without the temperature limit. After the temperature recovers for a period of time, the strong value of light will return to the initial value, which means that the 0603 patch LED lamp beads no matter how long they work, the initial light is strong and unchanged. It cannot be identified as light failure. 0603 patch LED lamp beads are decaying refers to the failure phenomenon that LED lamp beads are not recovered due to some material damage. The ratio of light flux. 0603 Patch LED Lighting Ball Bad Light Source Light False is mainly due to the inorganic material such as the colloidal temperature resistance. The main reason for the decline of light beads is that the colloidal temperature resistance is insufficient, and the best packaging glue temperature in front of the high -power LED lamp beads is only more than 100 degrees. Test proves that a 50W integrated light source is often in a sufficiently large radiator. Up to more than 200 degrees, whether it is irrigation or PPA in high temperature in a long time, it will inevitably constitute collagen cracking, carbonization, and the chip separately. From the lamp system, the light decay of LED lamp beads is related to the system thermal resistance, including heat dissipation channels, heat dissipation materials, heat dissipation methods, and temperature -related components, etc. The light decay of 060LED lamp beads is a supporting decision by the bracket structure, chip, fluorescent powder quality, colloidal temperature resistance, packaging craft plant and other conditions. The central technology of the bead LED lamp beads should be the research and development and manufacturing technology of the packaging stent. 0603 Patch LED Lighting Bad the reason for light decay today is here.
