Abstract
Description
Technical Field
[0001] This invention relates to the field of lighting technology, and more particularly to a stage lamp that combines heat dissipation and waterproofing. Background Technology
[0002] Traditional stage light heads typically consist of a light-emitting panel, a heat sink, and a driver plate arranged from top to bottom. One end of the heat sink is attached to the light-emitting panel to dissipate heat, while the other end houses a cooling fan and the driver plate. The driver plate and cooling fan reside within the same heat dissipation chamber, which is open to the outside environment. This allows the cooling fan to drive cool air from outside for heat exchange with the heat sink. However, the driver plate is susceptible to damage from moisture and dust. For example, Chinese utility model patent application discloses a stage light (publication number CN216480534U), which, in its specification (paragraphs 58-61 and appendix)... Figure 2 As can be seen from the disclosed content (shown), there is an urgent need for an electronic component mounting structure that can both ensure efficient heat dissipation and achieve reliable waterproof sealing, in order to improve the product's environmental adaptability and service life.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] As attached Figure 1 To be continued Figure 3 As shown, a stage light with both heat dissipation and waterproofing features includes a housing 1. A light outlet is located at the top of the housing 1. Inside the housing 1, a first heat dissipation plate 11 and a second heat dissipation plate 12 are spaced apart from top to bottom. A light-emitting plate 2 is disposed on the end face of the first heat dissipation plate 11 near the light outlet. The first heat dissipation plate 11 and the second heat dissipation plate 12 are supported and connected by several heat-conducting pipes 3. The second heat dissipation plate 12 is sealed to the inner wall of the housing 1, thus dividing the interior of the housing 1 into an upper cavity 101 and a lower cavity 102. The upper cavity 101 is a closed space, and an electronic component 4 is disposed within the upper cavity 101 between the first heat sink 11 and the second heat sink 12, so that the electronic component 4 is located within the closed space. In addition, the first heat sink 11 and the second heat sink 12 are connected by a heat pipe 3, which not only conducts heat but also provides support. The electronic component 4 is placed in the space formed between the first heat sink 11 and the second heat sink 12, which ensures efficient heat dissipation and achieves a reliable waterproof seal for the electronic component 4.
[0023] In this embodiment, the heat pipe 3 includes an integrally formed first bent section 31, a support section 32, and a second bent section 33. The heat pipe 3 makes thermal contact with the first heat sink 11 through the first bent section 31, and makes thermal contact with the second heat sink 12 through the second bent section 33. The heat generated by the light-emitting plate 2 is conducted to the second heat sink 12 through the first heat sink 11 and the heat pipe 3. The first bent section 31 and the second bent section 33 are bent, which can increase the contact area and is beneficial for stress and heat conduction.
[0024] In this embodiment, the heat pipes 3 are arranged in a ring shape, and the support section 32 is closer to the surrounding center formed by the heat pipes 3. The first bending section 31 and the second bending section 33 both extend outward along the direction gradually away from the surrounding center, thereby improving the heat uniformity of each heat sink.
[0025] In this embodiment, the first heat sink 11 has a first receiving groove whose shape matches the shape of the first bent section 31, and the second heat sink 12 also has a second receiving groove whose shape matches the shape of the second bent section 33. Specifically, the first bent section 31 and the second bent section 33 are both U-shaped, and the first receiving groove and the second receiving groove are also U-shaped, which increases the contact area between the bent part of the heat pipe 3 and the heat sink and further improves the heat dissipation efficiency.
[0026] In this embodiment, the electronic component 4 includes a driver board 41 electrically connected to the light-emitting plate 2. A first heat sink 42 is fixedly connected to the upper end of the second heat sink 12. The first heat sink 42 is used to fix the driver board 41 and provide heat dissipation for it. The heat generated by the driver board 41 during operation can be transferred to the second heat sink 12 through the first heat sink 42, thereby reducing the heat generation of the driver board 41 and maintaining its stable working state.
[0027] In this embodiment, the first heat sink 11 and the second heat sink 12 are fixedly connected by a plurality of connecting posts 5. The connecting posts 5 can increase the stability of the connection between the first heat sink 11 and the second heat sink 12. Preferably, the connecting posts 5 are made of metal to play a role in heat conduction.
[0028] In this embodiment, a second heat sink 6 and a cooling fan 7 are fixedly disposed at the lower end of the second heat sink 12 and located in the lower cavity 102. The lower cavity 102 is provided with a plurality of heat dissipation holes and communicates with the outside through the heat dissipation holes. The cooling fan 7 drives the external cold air to exchange heat with the second heat sink 6, thereby improving the heat dissipation efficiency of the second heat sink 6.
[0029] In this embodiment, the second heat sink 12 is provided with a breather valve 8 for gaseous communication between the upper cavity 101 and the lower cavity 102. The breather valve 8 is used to balance the air pressure of the upper cavity 101, and while maintaining the air pressure balance, it can also make the upper cavity 101 waterproof and dustproof.
[0030] In this embodiment, the light outlet is located in the upper cavity 101, and a light-transmitting tempered glass 9 is sealed to the light outlet. The tempered glass 9 is sealed to the light outlet through a sealing ring 10, which achieves the protective sealing of the light-transmitting area and ensures the optical transmission efficiency.
[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various equivalent changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
