Description

Technical Field

[0001] The utility model relates to the technical field of LED lamps, in particular to an LED lamp housing with good heat dissipation effect. Background Art

[0002] The LED lamp is an electroluminescent semiconductor material chip, which is cured on the bracket with silver glue or white glue, and then the chip and the circuit board are connected with silver wire or gold wire. The surrounding is sealed with epoxy resin to protect the internal core wire, and finally the shell is installed, so the LED lamp has good seismic resistance. The semiconductor chip consists of two parts, one is a P-type semiconductor, in which holes dominate, and the other end is an N-type semiconductor, which is mainly electrons. But when these two semiconductors are connected, a PN junction is formed between them. When the current acts on the chip through the wire, the electrons will be pushed to the P area, where the electrons and holes recombine, and then they will emit energy in the form of photons. This is the principle of LED light emission. The wavelength of light, that is, the color of light, is determined by the material forming the PN junction. Publication number: CN 203478116 discloses an LED downlight housing, including a housing and a power supply protection cover; the power supply protection cover is covered on the top of the housing and forms an internal space with the housing, and the internal space is used to accommodate the power supply box.

[0028] Working principle: during use, when the LED lamp is turned on, the micro motor 12 located inside the lamp housing 1 is also started. The heat generated during the use of the LED lamp will be dissipated through the heat sink 5. At the same time, the power output end of the micro motor 12 drives the fan blades 13 to rotate continuously. During the rotation of the fan blades 13, the outside air is sucked into the interior of the lamp housing 1 through the air inlet 3. At the same time, the air in the lamp housing 1 is blown out of the lamp housing 1 through the air outlet 4, and the heat generated by the LED lamp is taken out of the lamp housing 1, thereby achieving the heat dissipation of the LED lamp during use, avoiding heat accumulation or slow heat dissipation that causes the LED lamp to be damaged by heat. By providing the micro motor 12 and the fan blades 13, the heat in the lamp housing 1 can be blown out of the lamp housing 1. At the same time, the flowing air driven by the rotation of the fan blades 13 can also further improve the heat dissipation effect of the LED lamp, avoid heat accumulation in the lamp housing 1, and increase the service life of the LED lamp. When the lamp housing 1 and the lamp holder 2 need to be disassembled, , press the pressure rods 19 on both sides of the lamp housing 1, press the pressure rods 19 and hold the lamp holder 2 at the same time, the pressure rods 19 push the block 18 to slide toward the inside of the card slots 17, and the block 18 will squeeze the second spring 20 during the sliding process. When one end of the block 18 is completely removed from the limit slot 9, the lamp holder 2 will slide downward from the inside of the lamp housing 1 under the action of gravity, so as to separate the lamp holder 2 from the lamp housing 1. When the lamp holder 2 is fixedly connected to the lamp housing 1, it is only necessary to press the block 18 and hold the lamp holder 2 It can be pushed into the interior of the lamp housing 1. When the limiting groove 9 is aligned with the card slot 17, the card block 18 will push one end of the card block 18 into the interior of the limiting groove 9 under the action of the No. 2 spring 20, thereby realizing a quick fixed connection between the lamp holder 2 and the lamp housing 1, thereby improving the installation efficiency and convenience. By setting the pressure rod 19, the lamp holder 2 and the lamp housing 1 can be quickly separated, and the operation is simple. At the same time, it also provides convenience for the later replacement of the lamp holder 2, and there is no need to remove it from the roof together with the lamp housing 1.
