Technical Field

[0001] The invention relates to the technical field of heat dissipation of stage lamps, and in particular to a radiator capable of saving installation space and a stage lamp thereof. Background Art

[0002] Stage lights often use LED lamp beads as lighting elements, and the lamp beads are often set in a flat shape. With the upgrade of the demand for lighting brightness in stage scenery, the power of LED light emitters in stage lamps is getting higher and higher, and the volume requirements of stage lamps are tending to be miniaturized. Considering that the lamps must meet the design conditions such as optical path and size, the heat dissipation effect of the radiator of the miniaturized stage lamps cannot meet the requirements. The heat generated by the rapid increase in the internal temperature of the LED light emitter cannot be dissipated in time, resulting in a short service life of the lamp body and poor lighting effects. Therefore, we need to design a radiator that can effectively save installation space and meet the heat dissipation effect, which has become an urgent technical problem to be solved. Summary of the invention

[0010] Furthermore, two cooling fans are provided on both the front and rear sides of the substrate.

[0011] A stage lamp comprising the radiator capable of saving installation space comprises a radiator and a light source assembly, wherein the light source assembly is mounted on a mounting plate of the radiator.

[0016] It should be noted that, in the absence of conflict, the embodiments in the present application and the features described in the embodiments may be combined with each other. The present application is further described in detail below in conjunction with the drawings and specific embodiments.

[0017] In the description of the present invention, it should be understood that the terms "center", "middle", "longitudinal", "lateral", "height", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0018] As attached Figure 1 To Attachment Figure 3 As shown, a heat sink capable of saving installation space comprises a substrate 1, a mounting plate 2, a cold forged heat sink 3 and a plurality of heat dissipation tubes 4, wherein the upper end surface of the substrate 1 is fitted and connected with the mounting plate 2, and the lower end surface of the substrate 1 is fitted and connected with the cold forged heat sink 3, and both left and right sides of the substrate 1 are provided with heat dissipation fin groups 5 perpendicular to the substrate 1, and after the plurality of heat dissipation tubes 4 cross through part of the substrate 1, one end thereof passes through the heat dissipation fin group 5 on the left side, and the other end passes through the heat dissipation fin group 5 on the right side, and the heat dissipation fin group 5 is mainly composed of a plurality of heat dissipation fins 51 arranged in parallel with each other, and the heat dissipation fins 51 are bounded by the substrate 1. It is divided into a lower base section 511 and an upper extension section 512 extending upward (i.e., the light emitting direction of the light source assembly) so that the height H1 of the lower base section 511 is smaller than the height H2 of the upper extension section 512. In order not to affect the light path of the light source assembly, it is necessary to ensure that the substrate 1 and the mounting plate 2 for mounting the light source assembly are located in an effective position, and at the same time, the size requirements of the stage lamp must be met. Therefore, we design the height of the lower base section 511 of the heat dissipation fin 51 to be as short as possible, and the upper extension section 512 extends upward to the maximum extent, so as to increase the heat dissipation area of ​​the heat dissipation fin 51, improve the heat dissipation efficiency, save the installation space of the radiator, and reduce the weight of the lamp.

[0019] In addition, the cooling fans 6 are arranged on the front and rear sides of the base plate 1, which improves the cooling efficiency while ensuring that the longitudinal height of the entire radiator remains unchanged, thereby saving the installation space of the radiator in the longitudinal direction of the lamp housing.

[0020] Furthermore, the ratio of the height H1 to the height H2 is in the range of 0.35-0.40. Preferably, the ratio of the height H1 to the height H2 is 0.40, so that the structure of the radiator is compact and the design layout is more reasonable.

[0021] As attached Figure 3As shown, the heat dissipation tubes 4 are arranged in two rows in the upper and lower parts, and the two ends of the heat dissipation tubes 4 in the upper row are respectively passed through the upper extension sections 512 of the heat dissipation fins 51 on the left and right sides, and the two ends of the heat dissipation tubes 4 in the lower row are respectively passed through the lower base sections 511 of the heat dissipation fins 51 on the left and right sides to increase the thermal conductivity, so that the heat source of the light source is quickly transferred from the mounting plate, the substrate, and the heat dissipation tubes to the heat dissipation fins.

[0022] As attached Figure 3 As shown, the upper end surface of the substrate 1 is provided with a plurality of first grooves at intervals, the mounting plate 2 is provided with a second groove corresponding to each of the first grooves, the upper row of the heat dissipation tubes 4 are fixed between the first grooves and the second grooves, the lower end surface of the substrate 1 is provided with a plurality of third grooves at intervals, the cold forged radiator 3 is provided with a fourth groove corresponding to the third groove, and the lower row of the heat dissipation tubes 4 are fixed between the third groove and the fourth groove. The contact area between the heat dissipation tube 4 and the substrate 1, the mounting plate 2 and the cold forged radiator 3 is increased to improve the heat dissipation efficiency. The bottom end surface of the heat dissipation fin group 5 is flush with the bottom end surface of the cold forged radiator 3, so that the tail of the radiator is short and small, further saving the installation space.

[0023] Specifically, two cooling fans 6 are provided on both the front and rear sides of the base plate 1 to improve the cooling efficiency.

[0024] A stage lamp including the above-mentioned heat sink capable of saving installation space comprises a heat sink and a light source assembly 7, wherein the light source assembly 7 is mounted on a mounting plate 2 of the heat sink.

[0025] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various equivalent changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
