1. Heat dissipation promotes the long-life design of led lamps.
We know that the lamp will heat up if it is turned on for a long time, and the heat will damage the led lamp itself. Now it has become the key to design advanced packaging technology to completely solve the heat dissipation problem of led lamps. We say that the light of LED is reflected in the encapsulated natural resin, so we use a reflector, which is made of natural rubber and can change the direction of light on the side of the chip. In this case, we know that the reflector will learn the lesson of light and quickly reduce its extraction. So reducing the temperature of LED chip is our key factor, because it can better reduce the burden of slowing down the temperature of LED chip. At present, we can only improve the chip shape and place small-sized chips. The concept of LED life is solved by LED manufacturers by replacing packaging materials, and attention should also be paid to the distribution of fluorescent materials in packaging materials.

2. Efficient power matching is the key to long life of led lamps.
The increasing popularity of led lamps is inseparable from its high efficiency and long life, which is an important factor. We say that its power supply must be more efficient and its life should be at least the same as that of LED lights. European standards generally have strict restrictions on lighting equipment with power loss exceeding 25W. And the lighting equipment must meet the power factor requirements. Therefore, source PFC, that is, power factor correction, is necessary to keep the input and output voltages of current quite consistent.

3.ESD protection is an advantage of led lamp design.
With the improvement of brightness and energy efficiency of related lamps, prolonging the life of led lamps has become one of the main factors to promote the rapid development of solid-state lighting design based on high brightness light emitting diode (HB-LED). But not all HB-LEDs are excellent, which makes the application of ESD protection by manufacturers have a certain impact on the field application of HB-LEDs.

4. Components are the basis of led lamp design.
CBS25V 1P50A 1W as the driving module is characterized by high efficiency and constant current. It can be said that it is specially designed for driving LED lamps. The relevant output current can reach 1.5A, and in the range of 0 ~ 0~ 1.5A, the output current efficiency is over 90% ... On the basis of power saving, the temperature rise caused by module self-heating can be reduced. It has a wide input and output voltage range, built-in overvoltage protection function, and is safe and reliable to use.
Design of led lamp
Aluminum electrolytic capacitor plays an important role in the application time of LED driving circuit. Considering the cost and life comprehensively, once the electrolytic capacitor can meet the requirements, that is, it can keep consistent with the life of LED, then some short board problems in its LED driving will not be a problem.
Through the analysis of the above four points, we know that the solution to the long-life design of led lamps comes from its own characteristics. Including its components and the design of power supply, is a nearly perfect project. If we eliminate the above problems, the service life of led lamps will be greatly improved.
