Description

Technical Field

[0001] The invention relates to the field of heat dissipation and waterproof stage lamps, in particular to a waterproof lamp for stage with internal circulation heat dissipation. Background Art

[0002] With the development of society, in order to create special lighting effects indoors and outdoors, various special lamps have emerged. These lamps are widely used in places such as stages and hotels, and are generally referred to as stage lighting equipment. Among them, the main equipment for producing special light effects is stage lamps. The structure of stage lamps is mainly to set a light source at one end of a shell; set a lens at the end along the light path of the light source; related parts between the light source and the lens that can modulate the color, shape, intensity and pattern of the light; and moving parts outside the shell that can control the movement of the lamp.

[0003] The current stage lighting fixtures mainly adopt a rain-blocking structure for waterproofing, that is, the flowing air can flow in and out of the air holes of the stage lighting fixtures, but the rain will be blocked by the blocking sheet on the air holes to achieve the waterproofing of the entire lighting fixture. Obviously, this waterproof structure of the stage lighting fixture cannot block water from different directions, and cannot effectively block the intrusion of water jets or large waves. The existing high-end outdoor stage lighting field requires the waterproof level of the lighting fixture to meet IPx56 or even higher.

[0004] In order to improve the waterproof level of the lamp, it is necessary to increase the sealing degree of the stage lamp. However, increasing the sealing degree of the lamp will inevitably prevent the high-temperature airflow of the lamp from flowing inside and outside, which will greatly reduce the heat dissipation efficiency of the lamp and increase the weight and volume of the heat dissipation structure. If the sealing degree of the lamp is increased, the heat dissipation structure relies on air circulation and heat conduction of the radiator to dissipate heat, which will not be able to meet the instantaneous high power condition of the lamp. For excessively high temperature peaks, it is easy to cause damage to the light source and reduce the service life. In addition, in the existing stage lamps, the optical components that can modulate the color, shape, intensity and pattern of the light, and even the light source components, are arranged on the inner wall of the shell. The lamp shell is mainly a structure that is split from top to bottom, or a structure that is split from left to right, or even a structure with multiple splits. The shell needs to be disassembled during maintenance; the completely sealed shell structure needs to be completely dismantled for maintenance and inspection, which is not only difficult to repair and difficult to operate, but may even damage the originally intact components, and it is also easy to destroy its waterproof structure. Maintenance or inspection requires re-waterproof sealing processing, which is very inconvenient to operate.

The heat dissipation component 2 is sealed and connected to the opening at one end of the waterproof shell 1, the lens 3 is sealed and connected to the lens 3 at the opening at the other end of the waterproof shell 1, the optical component 4 is connected to the inside of the waterproof shell 1, the light source component 5 is connected to the inside of the waterproof shell 1 and is adjacent to the heat dissipation component 2, and the air supply component 6 forms an annular gas flow channel along the inside of the waterproof shell 1. The waterproof shell 1 is provided with a first fin group 11 on the inner walls on both sides of the annular gas flow channel, and the outer wall of the waterproof shell 1 is provided with a second fin group 12 corresponding to the position of the first fin group 11. When the lamp is in operation, the waterproof shell 1 can block the entry of water, and in order to improve the waterproof performance, it blocks the circulation of internal and external air, which plays the role of providing a mounting position for the lamp components and protecting the lamp components. The light source component 5 generates a light beam, and the optical component 4 adjusts the light beam according to the setting and emits it from the lens 3. When the light source assembly 5 is in operation, a large amount of heat will be generated, which will be transferred to the heat dissipation assembly 2, and the heat dissipation assembly 2 will be transferred to the outside by heat conduction. The air supply assembly 6 blows the high-temperature gas at the light source into the waterproof housing 1 and forms an annular gas flow channel. The annular gas will exchange heat with the first fin group 11 arranged on both sides of the waterproof housing 1. The heat absorbed by the first fin group 11 will be transferred to the second fin group 12 arranged on the corresponding two sides of the outside of the waterproof housing 1. The second fin group 12 will exchange heat with the outside air to achieve rapid cooling.

More specifically, the radial width of the waterproof housing 1 from one end of the heat dissipation component 2 to one end of the lens 3 decreases, the axial flow fan of the first air supply device 61 is installed at an eight-shaped relative angle, and the axial flow fan of the second air supply device 63 is installed at an inverted eight-shaped relative angle. The first fin group 11 includes a plurality of raised rib structures arranged on the inner wall of the waterproof housing 1, and the rib structure is arranged in the longitudinal direction, that is, arranged along the flow direction of the annular gas flow channel, which can facilitate the flow of internal gas. The second fin group 12 includes a plurality of raised rib structures arranged on the outer wall of the waterproof shell 1 corresponding to the position of the first fin group 11. The rib structure is also arranged in the longitudinal direction, which can facilitate the heat conduction of the first fin group 11. Regarding the shape of the waterproof shell 1, specifically, the radial cross-section of the two sides of the waterproof shell 1 provided with the first fin group 11 is an arc shape. This solution can increase the setting area of ​​the first fin group 11 and the second fin group 12, and also increase the contact area between the internal air fluid and the waterproof shell 1. It can be understood that the number of the first air supply device 61 and the second air supply device 63 can also be single or more than two, and the positions of their arrangement can be other positions where the annular gas flow channel is formed.

[0035] like Figure 1 , 2As shown in Figure 4, in order to further dissipate the heat inside the lamp holder in the lamp, the present embodiment specifically has the following features: the light source bracket 51 is also provided with a third air supply device 53, and the third air supply device 53 is a blower fan respectively provided on the upper and lower sides of the light source bracket 51.

The third fin group 22 located on the inner side absorbs the heat generated by the light source body 52, and transfers the heat to the fourth fin group 23 located on the outer side through the heat-conducting substrate 21. The fourth fin group 23 exchanges heat with the outside air through the air supplied by the fourth air supply device 24 to achieve rapid cooling of the heat-conducting substrate 21 and the fourth fin group 23. Specifically, but not limited to, the third fin group 22 is two heat sinks connected to both sides of the inside of the heat-conducting substrate 21 and located next to the second air supply device 63. The heat sink includes a plurality of fins and a heat-conducting copper tube connecting each fin. The air supply of the second air supply device 63 can flow through the gap between the fins.

The annular copper tubes are arranged in parallel in the middle of the heat-conducting substrate 21, and their width increases from the middle to the two sides. This solution increases the heat dissipation efficiency of the annular gas flow channel at the center.

The semiconductor cooling sheet 251 is based on the Peltier effect of semiconductors. When powered on, two ends with a temperature difference are formed. The cold end absorbs heat and the hot end emits heat. The cooling fin group 252 includes a bottom plate and a plurality of fins integrally connected to the bottom plate. The bottom plate is connected to the cold end of the semiconductor cooling sheet 251.
