At this time, the cold air located in the heat sink 10 rises and exits due to the heat absorption and expansion into the hot air with less density; due to the departure of the hot air, the air pressure difference is generated on the opposite sides of the heat sink 10, so that the heat sink 10 is located at the radiator 10. The cold air from the side enters the heat sink 10 from the gap between the heat radiating portion 13 and the through hole 135; after that, the cold air absorbs the heat on the heat sink 10 and turns into hot air again, thereby continuously achieving air convection, continuously Take away the heat from the LEDs. In this way, the LED can operate within the normal temperature range, ensuring the illumination of the fixture and extending its service life. In summary, the present invention complies with the requirements of the invention patent, and proposes a patent application according to law.
