Description

Technical Field

[0001] The utility model relates to the technical field of LED lighting fixtures, in particular to a radiator for LED stage lighting fixtures. Background Art

[0002] The radiator of the LED stage lighting fixture provides a key heat dissipation function for the LED light source through careful structural design. Its main structures include heat dissipation fins, a heat dissipation base, heat dissipation glue, thermal paste, a fan, etc. The large surface area of the heat dissipation fins increases the contact with the surrounding air, promoting heat dissipation to the environment through radiation and convection. The heat dissipation base serves as a bridge for heat conduction, effectively conducting heat from the LED components to the surface of the radiator. The heat dissipation glue or thermal paste fills the tiny gaps to improve the heat conduction efficiency.

[0003] For example, the novel radiator for LED lighting fixtures disclosed in the authorized publication number CN219414680U includes arc-shaped conduction ribs, straight conduction ribs, an LED light-emitting module installation area, and a connection panel. Connection columns are respectively arranged at both ends of the arc-shaped conduction ribs, and a wire passing hole is arranged in the middle. There are also 4 straight conduction ribs arranged on the reverse side of the arc-shaped conduction ribs. A second heat dissipation fin is arranged at the center of the straight conduction ribs. A third heat dissipation fin is arranged at the upper end of the second heat dissipation fin, and a first heat dissipation fin is arranged at the lower end. The distance between the arc-shaped conduction ribs and the arc-shaped conduction ribs is 11 - 12 mm, and the fourth heat dissipation fins are evenly distributed on the reverse side of the heat contact surface of the LED light-emitting module, enabling rapid exchange of cold air and hot air. However, in this technical solution, the multiple heat dissipation blocks are mainly connected through the arc-shaped conduction ribs and the connection panel, so that the multiple heat dissipation blocks form a columnar structure, resulting in relatively large assembly gaps between adjacent heat dissipation blocks, and there are problems of shaking and unstable assembly. In the working environment of stage lighting fixtures, the fixtures need to be moved frequently or are subject to vibration. Therefore, if the connection between the heat dissipation blocks is not firm, the fixtures will become loose or deformed, thereby affecting the performance and stability of the fixtures. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a radiator for LED stage lighting fixtures, which adhesively installs heat dissipation blocks at equal intervals on the outer peripheral surface of a hollow inner liner, and uses a double-layer lamp housing to gather and converge the hollow inner liner and several heat dissipation blocks on the outside, so as to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A radiator for LED stage lighting fixtures, comprising:

[0011] Preferably, the blowing structure includes a tray fixed between the plurality of ribs and a cooling fan installed inside the tray.

[0012] Preferably, a circular lip is integrally formed at the bottom end of the inner hollow column and the circular lip.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1-5 The utility model provides an embodiment: a heat sink for LED stage lighting fixtures, comprising a hollow inner tank 1, and a plurality of heat sink blocks 3 bonded at equal intervals on the outer peripheral surface of the hollow inner tank 1, an upper support plate 2 is fixed to the top of the hollow inner tank 1, and a plurality of connecting legs 5 are welded to the top of the upper support plate 2, and a support ring 4 is commonly installed on the outer walls of the plurality of connecting legs 5;

[0022] A double-layer lamp housing 9, the double-layer lamp housing 9 comprises an inner hollow column 901 and an outer protective housing 903, the outer protective housing 903 of the double-layer lamp housing 9 is installed on the outside of the plurality of heat sinks 3 and is bolted to the support ring 4, and the inner hollow column 901 of the double-layer lamp housing 9 is installed inside the hollow inner tank 1;

[0023] The inner hollow column 901 and the bottom end of the annular lip 902 are integrally formed with an annular lip 902, and the annular lip 902 is located inside the hollow inner shell 1, and the outer protective shell 903 is folded on the outside of the heat sink 3, and the outer protective shell 903 and the support ring 4 are bolted in a bolted manner. The double-layer lamp shell 9 folds and aggregates the hollow inner shell 1 and the heat sink 3 to make the appearance of the lamp more neat and beautiful, and the double-layer design of the outer shell can effectively hide the internal structure of the lamp, making the overall lamp more simple and neat;

[0024] The heat sink 3 is composed of the raised strips 301 bonded to the outer wall of the hollow inner container 1 and the fins 302 fixed to the outer walls on both sides of the raised strips 301. The outer walls of the fins 302 are provided with wavy grooves 303. The designs of the fins 302 and the wavy grooves 303 can effectively increase the surface area of the raised strips 301, helping to transfer heat to the surrounding environment more quickly and improving the heat dissipation efficiency.

[0025] On the inner wall of the hollow inner container 1, there are rectangular hollowed-out parts 101 corresponding to the positions of the heat sinks 3. The rectangular hollowed-out parts 101 enable the air to circulate further at an accelerated speed, thereby promoting the rapid conduction of heat.

[0026] At the top of the support ring 4, a dust-proof cage 6 is fixed. And at the central position inside the dust-proof cage 6, a central column 7 is installed. Inside the dust-proof cage 6, a blowing structure 8 is installed. The dust-proof cage 6 is composed of several rib strips 601 welded to the inner wall of the support ring 4. The ends of the rib strips 601 far from the support ring 4 bend downward and extend to be fixed to the outer wall of the central column 7. The bottom end of the support ring 4 is welded to the upper support plate 2 through several connecting feet 5. Thus, the hollow inner container 1, the heat sink 3, the support ring 4, and the dust-proof cage 6 form a complete radiator. The dust-proof cage 6 can effectively prevent dust, sundries and other impurities from entering the lamp, reducing their accumulation on the surface of the radiator and the influence on heat dissipation.

[0027] The blowing structure 8 includes a tray 801 fixed between several rib strips 601 and a cooling fan 802 installed inside the tray 801. During the operation of the lamp, the cooling fan 802 is connected to the power supply inside the lamp. By the way that the cooling fan 802 actively blows air downward, the heat on the hollow inner container 1 and the heat sink 3 can be quickly taken away.

[0028] When the embodiment of the present application is in use, first, the staff evenly coats an adhesive on the outer peripheral surface of the hollow inner container 1, and makes multiple heat sinks 3 be installed on the outer wall of the hollow inner container 1 at equal intervals in an adhesive-bonded form. The adhesive-bonded installation method of the heat sinks 3 can connect the heat sinks 3 and the hollow inner container 1 more tightly, ensuring that heat can be conducted to the outside of the lamp quickly and evenly. Subsequently, the staff takes out the double-layer lamp shell 9, makes the inner layer of the double-layer lamp shell 9 be sleeved inside the hollow inner container 1, and the outer layer of the double-layer lamp shell 9 cover the outside of several heat sinks 3. Thus, the double-layer lamp shell 9 further tightens the hollow inner container 1 and the heat sinks 3. Then, the support ring 4 and the double-layer lamp shell 9 are bolted. At this time, several heat sinks 3 are located between the double-layer lamp shell 9 and the hollow inner container 1. The double-layer lamp shell 9 effectively prevents the shaking between the heat sinks 3 and the problem of unstable lamp assembly, and can better adapt to complex environments such as stages.

[0029] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
