Background technique

With the advancement of science and technology, LEDs have higher luminous efficiency, lower cost, and no pollution. They are in line with the national theme of energy conservation and environmental protection, and are more and more popular among people. At present, the lifespan of the power supply device of the LED lamp is generally shorter than that of the light emitting device, and the cost is also much lower than that of the light emitting device, and it is prone to failure, which affects the stability of the LED lamp. Looking at the existing LED bulb lamps, in order to ensure the safety of the product, designers and manufacturers usually make the LED lamps into a whole, so that users are not allowed to disassemble them at will. Therefore, when the LED lamp power supply device fails, the user cannot replace the faulty and low-priced power supply device, and can only choose to discard the entire LED lamp and buy it again, resulting in great waste. Therefore, the assembly structure of the existing LED bulb lamp should be improved to solve the above problems. the
