Description

Technical Field

[0002] LED is a solid-state semiconductor device that can directly convert electrical energy into light energy. The heart of LED is a semiconductor chip. One end of the chip is attached to a bracket and is the negative pole, and the other end is connected to the positive pole of the power supply. The whole chip is encapsulated by epoxy resin. The semiconductor chip consists of two parts. One part 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 current acts on the chip through a wire, electrons will be pushed to the P region, where electrons and holes recombine, and then energy will be emitted in the form of photons. The existing LED lamps generate a lot of heat when working, and the existing LED lamps are usually fixed in place by brackets. Since the brackets are directly connected to the LED lamps, the existing brackets cannot dissipate the heat of the LED lamps, which makes the heat dissipation effect of the LED lamps poor, resulting in the heat generated by the LED lamps being difficult to dissipate.

[0022] An air filter assembly 5 is installed inside the ventilation disc 22, and the air filter assembly 5 includes a filter plate 51, a pull rod 52, a conical plate 53, a drop groove 54, a fixing frame 55, a filter screen plate 56, a hydraulic rod 57, a fixing disc 58, and a compression spring 59; A conical plate 53 is installed in the cavity opened inside the ventilation disk 22, and the conical plate 53 is in contact with the filter plate 51.

[0023] When the LED lamp body 1 is used for a long time, a large amount of heat will be generated inside the LED lamp body 1. At this time, the servo motor 45 is started, and the output end of the servo motor 45 drives one end of the movable rod 42 to rotate. At this time, the movable rod 42 drives the gear 41 to rotate, and because the rack 44 is meshed with the gear 41, when the gear 41 rotates, the rack 44 drives the semi-arc plate 43 to adjust the position. When the semi-arc plate 43 rotates, it drives the movable disk 23 to rotate. At this time, during the rotation process, the movable disk 23 slides on the surface of the adjusting arc plate 46 on one side of the support frame 13 through the arc groove opened on the surface of the movable disk 23. The adjusting arc plate 46 can support the position of the movable disk 23 to avoid the falling of the movable disk 23 and other devices during use, thereby improving the stability of the device. When the arc groove opened on the surface of the movable disk 23 is on the adjusting arc plate 46, the movable disk 23 is rotated. 6, the circular ring 47 in the arc groove slides in the through hole opened on the surface of the adjusting arc plate 46. The circular ring 47 and the adjusting arc plate 46 can support the position of the movable disk 23 and limit the rotation position of the movable disk 23 to avoid the position displacement of the movable disk 23 during the rotation process, so as to timely cool down the LED lamp body 1 with a high temperature, and avoid the high heat of the LED lamp body 1 during the long-term use of the LED lamp body 1. The LED lamp body 1 is not able to be dissipated in time, causing damage to some vulnerable parts of the LED lamp body 1. The outside air has enough air volume for heat exchange, so as to maintain efficient heat dissipation effect and extend the service life of the LED lamp body 1, so as to promote the circulation between the LED lamp body 1 and the outside air, so as to achieve the purpose of accelerating heat dissipation and extend the service life of the LED lamp body 1. When the movable disk 23 drives the rotating rod 27 to rotate during the rotation process, the movable disk 23 drives the rotating rod 27 to move its position. When the rotating rod 27 moves its position, the rotating rod 27 drives the arc plate 26 to adjust its position. At this time, the arc plate 26 slides on the surface of the rotating rod 27. During the rotation of the arc plate 26 on the surface of the rotating rod 27, the arc plate 26 drives the torsion spring 211 to deform. When the special-shaped opening and closing disk 24 is closed, the force of the torsion spring 211 to restore its shape can assist the special-shaped opening and closing disk 24 to close, which greatly improves the working efficiency of the device when in use, thereby making the arc plate 26 slide on the surface of the rotating rod 27. The shaped plate 26 can drive the special-shaped opening and closing disk 24 to adjust its position. When the special-shaped opening and closing disk 24 is in the process of adjusting its position, the special-shaped opening and closing disk 24 rotates on the surface of the rotating rod 25. The rotating rod 25 can not only fix the position of the special-shaped opening and closing disk 24, but also make the special-shaped opening and closing disk 24 rotate, so that the five special-shaped opening and closing disks 24 form a "disc" structure to open, and then the ventilation holes 210 of the ventilation pipe 28 are opened, so that the outside air enters the L along the movable disk 23, the ventilation pipe 28, the ventilation column 21, the ventilation disk 22 and the ventilation holes 210 opened inside the support frame 13 The ED lamp body 1 performs air exchange processing. When the outside air enters the ventilation hole 210, it can not only enter from the ventilation hole 210 opened on the surface of the movable disk 23, but also enter into the interior of the air duct 212 through the heat dissipation slot plate 213. At this time, the air duct 212 transports the air to the ventilation hole 210 opened on the surface of the movable disk 23, thereby greatly improving the effect of air exchange, so as to further improve the heat dissipation effect of the LED lamp body 1. When the outside air enters the ventilation hole 210 opened inside the support base 12, the air flows along the groove installed on the bottom surface of the support base 12. The plate 29 enters the LED lamp body 1, so as to perform heat dissipation treatment on the LED lamp body 1, so that the user does not need to perform manual operation, saving time cost, and when the temperature of the LED lamp body 1 is not high, the function of heat dissipation of the LED lamp body 1 can be turned off to avoid excessive heat dissipation of the LED lamp body 1, which affects the normal use of the LED lamp body 1 and meets the actual use needs. When the LED lamp body 1 needs to be cooled, the opening and closing of the ventilation hole 210 can be conveniently controlled, further improving the convenience of the device when used, so that the user can conveniently and quickly perform control operations; When the heat dissipation effect becomes worse after long-term use, the hydraulic rod 57 on the fixed frame 55 is started, and the telescopic end of the hydraulic rod 57 drives the pull rod 52 to slide in the cavity opened inside the ventilation disk 22. When the pull rod 52 is sliding, it squeezes the compression spring 59 through the fixed disk 58, so that the compression spring 59 is deformed, and the compression spring 59 can smoothly move the position of the pull rod 52, further improving the effect of the device when in use. At this time, the pull rod 52 pulls the filter plate 51 to slide. When the filter plate 51 is sliding, the conical plate 53 processes the dust on the surface of the filter plate 51, thereby preventing a large amount of dust from accumulating on the surface of the filter plate 51, causing poor air circulation, and affecting the heat dissipation effect of the LED lamp body 1. The dust processed from the surface of the filter plate 51 by the conical plate 53 falls into the outside world along the drop groove 54 opened inside the ventilation disk 22, so that the dust, dirt and other impurities on the filter plate 51 can be removed in time to prevent the filter plate 51 from being blocked, so that air can pass through the filter plate 51 without hindrance. When installing the LED lamp body 1, the LED lamp body 1 can be installed through the mounting plate 14 on the support frame 13. The surface of the mounting plate 14 is provided with mounting holes for installation. The staff uses bolts to thread the mounting holes on the surface of the mounting plate 14. At this time, one end of the bolt is threadedly connected to the position where the installation is required, thereby achieving the installation of the LED lamp body 1, which is convenient for the staff to install the LED lamp body 1, and the installation operation is relatively simple, avoiding complicated operations on the LED lamp body 1 during installation, wasting a lot of manpower and material resources, etc., and the bolt connection has strong stability, avoiding the support frame 13 from falling off as a whole during use.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
