Problems solved by technology

However, LED light sources are different from ordinary light sources. They need to drive circuit boards, and the heating problem of the drive circuit boards will seriously affect the service life of the entire LED lamp. Therefore, the application of LED light sources to lamps must solve the heat dissipation problem of the drive circuit.

Abstract

The invention provides an LED (Light Emitting Diode) lamp (100) which has both heat radiating function and electromagnetic shielding function. The LED lamp (100) comprises a shell (6) and an LED light source assembly which comprises an LED light source (4), a drive circuit board (9) and an LED light source switch control device. A heat radiating device which separates the LED light source (4) from the drive circuit board (9) is arranged in the LED lamp (1000) and comprises a main heat radiating board (1) and an auxiliary heat radiating board (2), and the auxiliary heat radiating board is attached to the main heat radiating board (1). Since the main heat radiating board (1) and the auxiliary heat radiating board (2) can effectively and reliably cool the drive circuit board (9) and the main heat radiating board (1) can cover the drive circuit board (9) effectively, therefore, the LED light source assembly achieves reliable electromagnetic shielding function and guarantees the stable working of the LED light source.

Description

technical field [0001] The invention belongs to the technical field of lighting. In particular, the present invention relates to LED lamps. Background technique [0002] As we all know, the lifespan of LED lights can be as long as 100,000 hours, and the lifespan under normal use can even exceed the lifespan of a person. In addition to having a long service life, LEDs also have the advantage of saving electricity. Ordinary LED lamps can provide continuous lighting for dozens of hours or even more than one hundred hours, which has obvious advantages compared with other lamps. Super power-saving and bright LED products are favored by many outdoor enthusiasts. However, LED light sources are different from ordinary light sources. They need to drive circuit boards, and the heating problem of the drive circuit boards will seriously affect the service life of the entire LED lamp. Therefore, the application of LED light sources to lamps must solve the heat dissipation problem of t...
