Description

Technical Field

[0001] The utility model relates to the technical field of waterproof heat dissipation structures for lamps, in particular to a novel internal and external double-circulation high-efficiency waterproof heat dissipation system. Background Art

[0002] With the development of society, in order to create special lighting effects indoors and outdoors, various specialized lamps have come into being. These lamps are used in a wide range of occasions, such as stages, hotels, etc., and are generally referred to as stage lighting equipment. The structure of stage lamps is mainly composed of a light source at one end of a shell, a lens at the end along the light path of the light source, and an optical component between the light source and the lens that can modulate the color, shape, intensity and pattern of the light.

[0003] Lighting equipment such as stage lamps are generally required to have certain waterproof and heat dissipation properties. Currently, the cooling systems used in high-power, fully sealed bubble (IP66) waterproof lamp holders on the market mainly rely on heat pipe fins plus fans for strong convection cooling, and multi-stage die-cast aluminum-magnesium alloy plus fans for strong convection cooling. These two cooling methods are also sometimes used in combination. Heat pipe fins are interlaced at the light source end of the lamp holder for heat conduction, with the heat pipes and fins located half inside and half outside the sealed lamp holder. The multi-stage aluminum-magnesium alloy die-cast parts are combined to form a sealed lamp holder body. An external fan placed at the bottom of the lamp holder creates an air duct along the lamp holder housing wrapped around the aluminum-magnesium alloy, forming a strong convection cooling system. However, these waterproof lamp holder cooling systems have the following technical problems: the waterproof structure is complex, and the heat generated by the light source cannot be effectively removed, affecting the heat dissipation performance. It is also impossible to effectively balance the waterproof and heat dissipation performance of the lamp. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] The utility model provides a novel internal and external dual-circulation, high-efficiency, waterproof heat dissipation system, comprising: a housing 1, a sealed waterproof heat dissipation body, an external circulation air intake fan 2, a first internal circulation fan 3, and a second internal circulation fan 4. A first receiving chamber is defined within the housing 1, and the external circulation air intake fan 2 and the waterproof heat dissipation body are accommodated within the first receiving chamber with a gap between them. The external circulation air intake fan 2 is located at the rear side of the housing 1, and the housing 1 has an air intake hole 5 corresponding to the external circulation air intake fan 2.

[0022] A second accommodating cavity is provided inside the waterproof heat dissipation main body, and a light source 6 is accommodated in the second accommodating cavity. The first internal circulation fan 3 and the second internal circulation fan 4 are respectively arranged on both sides of the light source 6. The upper inner wall of the waterproof heat dissipation main body and the upper outer wall of the second accommodating cavity form a first internal circulation air duct 7, and the lower inner wall of the waterproof heat dissipation main body and the lower outer wall of the second accommodating cavity form a second internal circulation air duct 8. The first internal circulation fan 3 is connected with the first internal circulation air duct 7, and the second internal circulation fan 4 is connected with the second internal circulation air duct 8. The outer wall of the waterproof heat dissipation main body and the inner wall of the outer shell 1 form an external circulation air duct 9. The front side of the outer shell 1 is provided with an external circulation air outlet 10, and the external circulation air duct 9 is connected with the external circulation air outlet 10.

[0023] It can be understood that the waterproof heat dissipation body of the present invention is a waterproof sealing body of the lamp holder. The waterproof heat dissipation body adopts a sealing setting, which can prevent moisture from entering the interior of the waterproof heat dissipation body to avoid affecting the normal use of components such as the light source 6, thereby playing a waterproof role.

[0024] In addition, the waterproof heat dissipation body of the present invention can also play a heat dissipation role. Through a simple internal circulation convection system (a first internal circulation fan 3, a second internal circulation fan 4, a first internal circulation air duct 7, and a second internal circulation air duct 8) plus an external circulation convection system (an external circulation air intake fan 2 and an external circulation air duct 9), strong convection heat dissipation is performed by three fans inside and outside the waterproof heat dissipation body: the first internal circulation fan 3 of the internal circulation convection system cooperates with the first internal circulation air duct 7, and the second internal circulation fan 4 cooperates with the second internal circulation air duct 8 to circulate the high-temperature air flow heat of the light source 6 at high speed and close to the inner wall of the waterproof heat dissipation body from the lamp holder to the lamp head infinitely, and the heat of the first internal circulation air duct 7 and the second internal circulation air duct 8 is conducted to the external circulation air duct 9 through the waterproof heat dissipation body; at the same time, the external circulation air intake fan 2 takes in air from the outside through the air inlet hole 5, and the heat of the light source 6 is taken away from the external circulation air outlet 10 to the outside through the external circulation air intake fan 2 along the air duct formed by the outer shell 1 that is wrapped around the waterproof heat dissipation body as a whole, that is, the external circulation air duct 9, thereby realizing strong convection heat dissipation of the heat of the light source through both inside and outside circulation.

[0025] Specifically, the waterproof heat dissipation body includes a waterproof heat dissipation shell 11, a front sealing plate 12 and a rear sealing plate 13. The front sealing plate 12 is sealed and connected to the through hole on the front side of the waterproof heat dissipation shell 11, and the rear sealing plate 13 is sealed and connected to the through hole on the rear side of the waterproof heat dissipation shell 11. The light source 6, the first internal circulation fan 3 and the second internal circulation fan 4 are all arranged on the rear sealing plate 13; the outer wall of the waterproof heat dissipation shell 11 and the inner wall of the outer shell 1 form an outer circulation air duct 9. It can be understood that through the simple structural arrangement of the waterproof heat dissipation shell 11, the front sealing plate 12 and the rear sealing plate 13, the interior of the waterproof heat dissipation body surrounded by the three is formed into a sealed space, thereby preventing moisture from entering the interior of the waterproof heat dissipation body, further avoiding moisture from affecting the normal use of components such as the light source, and playing a waterproof role. In addition, the above-mentioned waterproof heat dissipation shell 11 can be connected and fixed to the inner wall of the outer shell 1 through a connecting structure of the existing technology such as a connecting column, and the front sealing plate 12 and the rear sealing plate 13 can also be connected to the outer shell 1.

The main components of drawn aluminum include aluminum and other alloy elements, such as copper, manganese, magnesium, etc. Drawn aluminum has good thermal conductivity, corrosion resistance, high strength and other characteristics. The thermal conductivity coefficient of drawn aluminum is 201W / MK, which is much larger than the thermal conductivity coefficient of die-cast aluminum-magnesium alloy, etc., and can improve the efficiency of the waterproof heat dissipation shell 11 in transferring heat from the first internal circulation air duct 7 and the second internal circulation air duct 8 to the external circulation air duct 9, that is, improve the heat dissipation efficiency; the front sealing plate 12 and the rear sealing plate 13 can also be made of drawn aluminum. In addition, the waterproof heat dissipation shell 11 can also be made of other metal materials with good thermal conductivity in the existing technology, and there are no excessive restrictions here.

[0027] In addition, the waterproof heat dissipation body further includes an upper partition 14 and a lower partition 15. The front sealing plate 12, the rear sealing plate 13, the upper partition 14, and the lower partition 15 form a second receiving chamber. The upper inner wall of the waterproof heat dissipation shell 11 and the outer wall of the upper partition 14 form a first internal circulation air duct 7, and the lower inner wall of the waterproof heat dissipation shell 11 and the outer wall of the lower partition 15 form a second internal circulation air duct 8. The first internal circulation fan 3 is connected to the first internal circulation air duct 7 through the first air guide groove 16 to conduct heat from the light source 6, and the second internal circulation fan 4 is connected to the second internal circulation air duct 8 through the second air guide groove 17.

[0028] Specifically, a lens 18 is provided on the front cover 1, and the lens 18 is arranged close to the external circulation air outlet 10. An optical component 19 is provided between the light source 6 and the lens 18. The light source 6 generates a light beam, and the optical component 19 modulates the light beam in terms of light color, shape, intensity, pattern, etc., and emits it from the lens 18; the above-mentioned light source 6, optical component 19, and lens 18 are all existing technologies and will not be elaborated here.

[0029] The outer circulation air outlet 10 is specifically annular. In addition, preferably, the outer wall of the waterproof heat dissipation shell 11 is provided with heat dissipation blades 20 to improve the thermal conductivity of the waterproof heat dissipation shell 11. Specifically, the heat dissipation blades 20 can be provided on both the upper outer wall and the lower outer wall of the waterproof heat dissipation shell 11, and the heat dissipation blades 20 are provided corresponding to the outer circulation air duct 9.

That is, the present invention can better take into account the waterproof performance and heat dissipation performance of the lamp at the same time; (2) The system of the present invention The design and assembly are simple, the number of fans used is very small, the structure is simple, and subsequent maintenance is convenient and quick; (3) The system design of the utility model eliminates the traditional design of the heat pipe fin combination scheme, and also eliminates the magnesium-aluminum alloy and die-cast aluminum shell sealing structure scheme. The utility model can significantly reduce the cost of the lamp holder while significantly improving the heat dissipation efficiency; (4) Due to the simple sealing design structure of the waterproof heat dissipation body, the waterproof sealing stability is also greatly improved; (5) The design structure of the utility model is compact, which greatly reduces the overall size of the lamp holder, and can make the entire lamp significantly smaller than the same type of waterproof products in the same industry.
