Problems solved by technology

[0003] According to statistics, the service life of general LED light sources is more than 10 years, while the service life of power supplies is about 2 years, which has led to the fact that it is widely used due to its long service life. Applicable LED light sources cannot be fully utilized due to the service life of the power supply

Abstract

The invention discloses an LED (Light-Emitting Diode) lamp device with a heat-radiating function, which comprises a lamp, wherein a power supply is installed at the inner part of the lamp, a heat-radiating plate is installed below the power supply, a PCB (Printed Circuit Board) is arranged below the heat-radiating plate, the PCB is connected with an LED light source through heat-conducting glue, and round gas-discharging holes are arranged in a lamp body. The LED lamp device has a simple structure, a used material is a commonly-used industrial material, and the LED lamp device has the characteristics of heat radiation, low cost and the like.

Description

technical field [0001] The invention relates to an LED lamp device, in particular to an LED lamp device with heat dissipation function. Background technique [0002] LED light source products are energy-saving and money-saving compared with incandescent lamps by 90%, the life span is 50 times that of traditional bulbs, and the price is 50% of the top products in the same industry. LED is a photoelectric device. And very popular. LED is a photoelectric device, only 15% to 25% of the electric energy is converted into light energy during its working process, and the rest of the electric energy is almost all converted into heat energy, which increases the temperature of the LED. In high-power LEDs, heat dissipation is a big problem. For example, if a 10W white light LED has a photoelectric conversion efficiency of 20%, 8W of electrical energy will be converted into heat energy. If no heat dissipation measures are taken, the core temperature of the high-power LED will rise rapi...
