Description

Technical Field

[0001] This utility model belongs to the field of stage lighting technology, specifically relating to an LED lamp head front cover. Background Technology

[0002] Heat dissipation is one of the core technologies in this field for LED stage lights, as its performance directly affects the stability, light decay rate, and lifespan of the lighting fixture. Currently, common LED stage light heat dissipation solutions mainly rely on installing heat sinks and fans on the rear shell and bottom of the fixture, using forced air cooling to create an airflow channel from back to front to remove the heat generated by the LED modules.

[0003] When using existing high-power-density LED stage light heads, heat tends to accumulate, especially in the front area (near the front cover of the light head). Although there are various mature heat dissipation designs, most of them focus on optimizing the rear of the light fixture and do not specifically enhance the heat dissipation capacity of the front cover area, which affects the overall heat dissipation efficiency of the stage light and thus affects its normal use.

[0011] Preferably, a sealing sleeve is provided between the filter frame and the mounting frame, and the sealing sleeve is movably fitted on the outside of the insertion frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes a heat-conducting plate and frame to transfer and absorb heat from the lamp holder when the light source is operating.

[0020] 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.

[0021] Example 1

[0022] Please see Figure 1-4 This embodiment provides the following technical solution: an LED lamp head front cover, including a housing 1, a lamp holder 2 fixedly connected to the front end of the housing 1, and a lamp source 3 disposed on the outside of the lamp holder 2. In some embodiments, the rear end of the housing 1 is an air inlet end, and a rear cover is also disposed at the rear end of the housing 1. An air inlet hole is disposed on the rear cover, and a heat dissipation fan is disposed inside the rear cover.

[0023] The housing 1 is equipped with a heat dissipation mechanism, which includes a heat-conducting plate 4, a heat-conducting frame 5, and heat dissipation holes 6. The heat-conducting plate 4 is detachably connected to the lamp holder 2, and the heat-conducting frame 5 is fixedly connected to the outside of the heat-conducting plate 4. The heat-conducting frame 5 is provided with heat dissipation fins 7, and the side wall of the housing 1 is provided with heat dissipation holes 6. Through the heat-conducting plate 4 and the heat-conducting frame 5, the heat on the lamp holder 2 is transferred and absorbed when the lamp source 3 is working. The heat dissipation fins 7 on the heat-conducting frame 5 further conduct the heat, and the heat is transferred to the outside through the heat dissipation holes 6, which improves the heat dissipation efficiency of the stage lamp when it is working and ensures the normal use of the stage lamp.

[0024] In some embodiments, two sealing plates 8 are fixedly connected at intervals below the lamp holder 2 inside the housing 1. A flow cavity is formed between the two sealing plates 8 and the inner wall of the housing 1. The sealing plates 8 are provided with mounting grooves that are adapted to the heat conduction frame 5. A plurality of heat dissipation holes 6 are provided. The plurality of heat dissipation holes 6 are circumferentially distributed on the housing 1 and communicate with the flow cavity. Through the provided flow cavity, the heat of the heat dissipation fins 7 on the heat conduction frame 5 can be guided into the flow cavity while the air at the air inlet blows into the heat conduction frame 5. The heat in the flow cavity can then be guided to the outside through the plurality of heat dissipation holes 6, thereby achieving the effect of heat dissipation and flow guidance.

[0025] Both sides of the housing 1 are provided with shaft grooves 9, and a rotating shaft is rotatably connected in the shaft grooves 9. The rotating shaft is fixedly connected to the lamp holder. Through the shaft grooves 9 and the rotating shaft, the housing 1 can be rotated on the lamp holder. The position of the lamp source 3 can be adjusted by adjusting the position of the housing 1.

[0026] Example 2

[0027] In some embodiments, a dustproof mechanism 10 is also included. The dustproof mechanism 10 includes a mounting frame 101 and a filter frame 102. The mounting frame 101 is fixedly connected inside the heat dissipation hole 6. A plug-in frame 103 is fixedly connected to one side of the filter frame 102 opposite to the mounting frame 101. The plug-in frame 103 is movably plugged into the mounting frame 101. A dustproof net 104 is fixedly connected to the other side of the filter frame 102. By setting the dustproof net 104, dust in the outside air will not enter the inside of the housing 1 when the external wind pressure is greater than the internal wind pressure of the housing 1, thereby improving the service life of the stage light. It can also prevent external debris from entering the inside of the housing 1 while the heat dissipation hole 6 is dissipating heat.

[0028] It also includes a fixing component, which includes two connecting rings 105. The two connecting rings 105 are fixedly connected to the mounting frame 101 and the filter frame 102 respectively. The two connecting rings 105 are detachably connected. In some embodiments, the two connecting rings 105 are detachably connected by bolts. The connecting rings 105 facilitate the disassembly and assembly of the filter frame 102, thereby allowing the dustproof net 104 to be cleaned or replaced.

[0029] A sealing sleeve is also provided between the filter frame 102 and the mounting frame 101. The sealing sleeve is movably fitted on the outside of the insertion frame 103. The sealing sleeve can increase the sealing between the filter frame 102 and the mounting frame 101.

[0030] The working principle of this utility model is as follows: When the lamp source 3 is working normally, the heat generated by the lamp source 3 is transferred to the lamp holder 2 in sequence. The heat on the lamp holder 2 is then transferred to the heat dissipation fins 7 through the heat conduction plate 4 and the heat conduction frame 5. At the same time, the air inlet at the rear end of the housing 1 is operated to allow outside air to enter the housing 1. The outside air passes through the heat dissipation fins 7 and carries away the heat on the heat dissipation fins 7, thereby transferring the heat inside the housing 1 to the outside through the heat dissipation holes 6, achieving the purpose of heat dissipation.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
