Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for beam lamps, and more specifically, to a lightweight and efficient heat dissipation beam lamp. Background Technology

[0002] A beam lamp, also known as a spotlight, concentrates a light source onto a single focal point to create a beam of light. It is renowned for its unique light source, characterized by a small-diameter bulb design and precise focal length positioning, resulting in extremely high light efficiency. For example, patent CN215831760U discloses a lightweight, high-efficiency heat-dissipating beam lamp. The condensate in the condenser tube absorbs heat, and a condenser pump cools the condensate before returning it to the tube, creating a continuous cycle for heat dissipation. If the beam lamp operates in an area with airflow, the airflow passes through ventilation slots and creates vortices between the inclined heat dissipation fins, expelling the hot air from the lamp's casing and accelerating the release of heat absorbed by the heatsinks. If there is no airflow during operation, a fan is required to create airflow.

[0003] When the above-mentioned device is in use, the fan cover and filter screen prevent dust from entering the housing of the beam lamp and attaching to the heat sink, which would affect the heat dissipation efficiency. However, during heat dissipation, external moisture can easily enter the interior of the beam lamp body, affecting the lifespan of the beam lamp and the working environment. At the same time, the heat sink cannot directly contact the heat source, thus affecting the heat dissipation efficiency of the beam lamp. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a lightweight and efficient heat dissipation beam lamp. The technical problem to be solved by the present invention is: how to increase the heat dissipation efficiency of the beam lamp while preventing external moisture and dust from entering the beam lamp.

[0011] In a preferred embodiment, the inner end face of the beam lamp housing is provided with a limiting sealing plate on the side near the annular sealing plate, and a plurality of locking screws are provided on one side of the outer end face of the heat sink.

[0012] In a preferred embodiment, a compression spring is provided on one side of the outer end face of the locking screw, and a cooling motor is provided in the middle of the radiator;

[0013] The outer end face of the radiator is provided with multiple mounting lugs, and the outer end face of the mounting lugs is provided with mounting screws.

[0014] In a preferred embodiment, the inner end face of the beam lamp housing is provided with a dustproof plate on the side near the heat sink, and a plurality of mounting protrusions are provided on one side of the outer end face of the dustproof plate.

External cold air then enters the beam lamp housing through the annular ventilation cover and air inlet, effectively increasing the heat dissipation efficiency of the beam lamp. Furthermore, after the heat sink is installed, the control chip is kept in a sealed state, preventing external moisture and dust from entering one side of the heat sink and avoiding the accumulation of dust and moisture on the circuit board surface, which could affect its working environment and lifespan.

[0028] This utility model provides a lightweight and efficient heat dissipation beam lamp, such as Figure 1 and 2 As shown, it includes a mounting base 1, with a beam lamp housing 6 on the outer side of the upper end of the mounting base 1, and a heat sink 11 inside the beam lamp housing 6;

[0029] The outer end face of the heat sink 11 is provided with a plurality of heat sink fins 12, one side of the inner end face of the beam lamp housing 6 is provided with a heat sink 14, one side of the outer end face of the beam lamp housing 6 is provided with an annular ventilation cover 13, and both sides of the lower end of the mounting base 1 are provided with mounting lugs 2, which can facilitate the installation and fixation of the mounting base 1 through the mounting lugs 2.

[0030] The mounting base 1 has a rotating base 3 at the middle of its upper end. The rotating base 3 has a fixed bracket 4 at its upper end. The rotating base 3 supports the fixed bracket 4, allowing the fixed bracket 4 to rotate and be adjusted around the rotating base 3. The outer end face of the beam lamp housing 6 has transverse rotating blocks 5 on both sides, which support the beam lamp housing 6 and facilitate the rotation and adjustment of the beam lamp housing 6 around the transverse rotating blocks 5. The inner end face of the beam lamp housing 6 has a protective lens 7 on one side.

[0031] The beam lamp housing 6 has a light speed lamp cover 8, a circuit board 9 and a control chip 10 inside. The heat sink 14 has a heat dissipation motor 15 in the middle. The heat sink 11 and the heat dissipation fins 12 are both made of aluminum alloy. When the beam lamp is working for a long time, the control chip 10 will dissipate a lot of heat. The heat sink 11 will be attached to the outer end face of the control chip 10 and absorb the heat of the control chip 10. The heat absorbed by the heat sink 11 will be transferred to the heat dissipation fins 12.

[0032] The metal circuitry on the surface of the circuit board 9 is electrically connected to the external control device, and the heat dissipation motor 15 is electrically connected to the external control device.

[0033] like Figure 3 , 4 As shown in Figure 5, a concave mounting groove 26 is provided on the outer end face of the heat sink 11, and a sealing gasket 21 is provided inside the concave mounting groove 26. When the heat sink 11 is installed, the sealing gasket 21 will fit against the inner end face of the beam lamp housing 6, thereby ensuring the sealing of one side of the heat sink 11. A plurality of connecting support plates 24 are provided on one side of the inner end face of the annular ventilation cover 13.

[0034] The outer end face of the beam lamp housing 6 has multiple air inlets 25 on the inner side of the annular ventilation cover 13. A first limiting baffle 18 is provided on one side of the inner end face of the beam lamp housing 6. An annular sealing plate 19 is provided on one side of the inner end face of the limiting baffle 18. After the heat sink 11 is installed, the outer end face of the protruding part on one side will fit into the inside of the annular sealing plate 19, thereby preventing external moisture from entering one side of the heat sink 11 and thus affecting the working environment of the circuit board 9.

[0035] The inner end face of the beam lamp housing 6 is provided with a limiting sealing plate 16 on the side near the annular sealing plate 19.

When the locking screws 22 lock and fix the heat sink 11, the compression spring 23 will press against the heat sink 11, so that the heat sink 11 is always in contact with the inside of the control chip 10, while avoiding the heat sink 11 pressing the control chip 10 too tightly and causing damage to the control chip 10.

[0036] The outer end face of the heat sink 14 is provided with a plurality of mounting lugs 27, and the outer end face of the mounting lugs 27 is provided with mounting screws, which can facilitate the installation and fixing of the heat sink 14.

The dustproof plate 17 can prevent large particles of dust from entering the interior of the beam lamp housing 6.

[0037] The dustproof plate 17 has multiple mounting protrusions 20 on one side of its outer end face. The mounting protrusions 20 can effectively increase the convenience of installing and disassembling the dustproof plate 17. The dustproof plate 17 is connected to the beam lamp housing 6 by threads. The outer end face of the concave mounting groove 26 is in contact with the outer end face of the sealing gasket 21. The sealing gasket 21 is a rubber component. The inner end face of the annular sealing plate 19 is in contact with one side of the outer end face of the heat sink 11.

[0038] The inner end face of the limiting sealing plate 16 is in contact with the outer end face of the heat dissipation fins 12. The heat dissipation motor 15 is electrically connected to the external control equipment. The surface of the dustproof plate 17 has multiple ventilation holes. When the heat dissipation motor 15 is working, it will exhaust the air inside the beam lamp housing 6 to the outside. When the air flows to the outside, it will take away the heat from the surface of the heat dissipation fins 12, thereby dissipating heat from the beam lamp. The cold air from the outside will be introduced into the interior of the beam lamp housing 6 from the annular ventilation cover 13 and the air inlet 25.
