Description

Technical Field

[0001] This utility model relates to the field of LED lighting technology, specifically to a heat dissipation structure for LED lights. Background Technology

[0002] LED lights are solid-state lighting devices based on light-emitting diode technology. Their core principle is to directly convert electrical energy into light energy through the electroluminescence effect of semiconductor materials. They are characterized by high efficiency, energy saving, environmental friendliness, and long lifespan. Unlike traditional light sources (such as incandescent and fluorescent lamps), LEDs emit light through the recombination of electrons and holes in a semiconductor PN junction, eliminating the need to heat the filament or excite gas, making them a cold light source. LED lights represent the next generation of lighting technology. With their high efficiency, durability, and multifunctionality, they are comprehensively replacing traditional light sources and becoming the mainstream choice for green lighting. With technological advancements, LEDs are developing towards higher luminous efficacy and greater intelligence (such as adjustable color temperature and IoT control), showing enormous potential in sustainable energy and smart cities.

[0003] In recent years, with the increase in the number and power of LEDs in LED lighting fixtures, the heat generated during LED lighting fixture operation has also gradually increased. LEDs use the aluminum substrate of the LED and the natural heat dissipation performance of the housing itself to conduct away the heat generated during operation. However, due to the small size of the aluminum substrate of the LED, the efficiency of passive heat dissipation is not high. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 This utility model discloses an LED lamp heat dissipation structure, including a lamp body 1. A fixing ring 2 is fixedly connected to the bottom outer wall of the lamp body 1. Heat sinks 15 connected to the outer wall of the lamp body 1 are evenly provided at the top of the fixing ring 2.

A cover 5 that covers the heat sinks 15 is fixedly connected to the top of the connecting ring 4. A ventilation opening 6 distributed in a ring is opened at the top of the cover 5. An installation plate 7 with a circular hole is fixedly installed in the inner cavity of the cover 5 above the lamp body 1. A fan 8 that matches the central hole is installed on the installation plate 7.

[0020] Specifically, a terminal block 9 is installed on the top of the cover 5.

[0021] The ventilation opening 6 is arranged around the terminal block 9.

[0022] The bottom of the mounting plate 7 is fixedly connected to a U-shaped frame 10, the bottom of the U-shaped frame 10 is fixedly connected to a connecting cylinder 12, the top of the connecting cylinder 12 is provided with a slot 13, the top inner wall of the slot 13 is connected to an electrode 14 by a spring, and the top of the lamp body 1 is equipped with a conductive post 11 that can be inserted into the slot 13 and contact the electrode 14.

[0023] In this embodiment, the vents 6 are arranged in a ring on the top of the cover 5, and the terminal blocks 9 are surrounded by the ring-shaped vents 6.

[0024] The U-shaped frame 10 has a corresponding wire-passing groove inside, which is connected to the inner cavity of the slot 13. The wire-passing groove has a wire that is electrically connected to the spring and the pole piece 14. One end of the wire can pass through the mounting plate 7 and be electrically connected to the terminal 9.

[0025] Specifically, the lamp body 1 has a lamp plate 17 for mounting LED beads inside, a lamp cover 18 at the bottom of the lamp body 1, and a reflector cup 16 inside the lamp body 1. The LED beads on the lamp plate 17 are located in the inner cavity of the reflector cup 16.
