It should be noted that an increase in temperature will reduce the internal resistance of LED beads. When the external temperature increases, the internal resistance of LED bead light sources will decrease. If a regulated power supply is used for power supply, it will cause an increase in LED working current. If it exceeds its rated working current, it will affect the service life of LED products, and in severe cases, it will cause the LED bead light source to "burn out". Therefore, it is best to choose a constant current source for power supply to ensure that the working current of LED is not affected by external temperature. LED bead temperature is also the most important factor affecting LED lifespan. Please take it seriously.
No matter what LED bead product it is, as long as it is applied outdoors, it faces the problem of waterproof and moisture-proof sealing. If not handled properly, it will directly affect the service life of LED products. Nowadays, a small number of manufacturers with high requirements for product quality use the traditional epoxy resin "pouring" method to seal LED products. This method is more cumbersome to operate, and is not very suitable for larger LED bead products, which can also cause an increase in product weight.
