Description

Technical Field

[0001] The utility model relates to the technical field of stage lamps, and more specifically to a lightweight circulating heat dissipation stage lamp. Background Art

[0002] As a stage lamp, stage lights are lighter, smaller and more functional to meet market demand. However, during the operation of the lamp, components inside the lamp head, such as light sources and motors, will generate a lot of heat. In the prior art, the heat dissipation efficiency of the lamp head through the heat exchange between the lamp housing and the outside world is low, or multiple heat dissipation fans are stacked to increase the gas flow rate, which leads to occupying too much space inside the stage lamp. There is an urgent need for a heat dissipation technology that can improve the heat accumulation of the lamp head without occupying too much space. Utility Model Content

[0003] In order to overcome at least one defect of the above-mentioned prior art, the utility model provides a lightweight stage lamp with circulating heat dissipation, which conducts the heat generated by the components inside the lamp head to the support frame, cools the area through the area where the heat dissipation fins are set, and the airflow after cooling re-enters the interior of the lamp head to dissipate heat and cool the interior of the lamp head, reduces the heat accumulation inside the lamp head, brings the heat out of the lamp head, increases the circulation path of the airflow carrying the heat, and improves the heat dissipation efficiency.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a lightweight circulating heat dissipation stage lamp, comprising a U-shaped support arm and a lamp head pivotally connected between the support arms, the support arm and the lamp head are connected by a pivot shaft, the pivot shaft is provided with a through-axis hole, a heat dissipation duct is formed inside the support arm, the heat dissipation duct is connected with the inside of the lamp head through the through-axis hole, and the outer side wall of the heat dissipation duct is provided with heat dissipation fins.

[0005] The support arm and the lamp holder are connected by a pivot axis, and the pivot axis is provided with an axial hole to provide a heat dissipation duct for the heat accumulated inside the lamp holder to flow out of the lamp holder. Heat dissipation fins are arranged on the outer wall of the heat dissipation duct to effectively increase its heat dissipation area and improve the heat dissipation efficiency. When the gas carries heat and flows to the heat dissipation duct, the heat is discharged to the outside through heat transfer, and the cooled gas will re-enter the lamp holder through the axial hole on the other side. In this way, the gas circulation path can be enlarged, the heat dissipation area can be increased, and the heat dissipation can be accelerated.

[0006] Furthermore, the support arm includes a housing, and the housing is provided with ventilation holes corresponding to the heat dissipation fins. The ventilation holes can help external cold air enter the lamp housing, and the cold air directly contacts the heat dissipation fins, thereby accelerating the heat exchange efficiency of the heat dissipation fins.

[0007] Furthermore, the ventilation holes are arranged in an array. The array arrangement is regular and versatile, and does not require separate mold opening and processing.

[0008] Furthermore, the inner side of the shell is provided with transverse reinforcing ribs, the heat dissipation fins extend vertically, and avoidance grooves are provided corresponding to the reinforcing ribs. The reinforcing ribs can increase the structural strength of the shell, making it less prone to bending and deformation, and the avoidance grooves can prevent the reinforcing ribs from directly contacting the heat dissipation fins and causing friction interference.

[0009] Furthermore, the heat dissipation duct is provided with a plurality of guide heat absorbing sheets on the inner side wall along the length direction thereof, and the guide heat absorbing sheets directly contact the gas carrying heat from the inner side wall, further increasing the heat exchange contact area.

[0010] Furthermore, the support arm includes a horizontal section and a vertical section, the heat dissipation duct includes a horizontal channel and a vertical channel, and the heat dissipation fin is located on the vertical channel. The combination of the horizontal channel and the vertical channel can increase the circulation path of the gas after it comes out of the lamp holder, and the vertical channel is closer to the lamp holder than the horizontal channel, so the heat accumulation is greater. Placing the heat dissipation fin in the vertical channel can contact the heat more quickly.

[0011] Furthermore, the support arm further comprises a heat dissipation cover, which is arranged on the through-axis hole to form the vertical channel. The heat dissipation cover directly covers the through-axis hole to form a sealed space, so that heat can directly enter the vertical channel through the through-axis hole for heat dissipation, with a simple structure and a simple heat dissipation path.

[0012] Furthermore, the vertical section has a supporting side plate and a heat dissipation cover, the vertical channel is formed by the heat dissipation cover buckled on the supporting side plate, and the heat dissipation fins are located on the outer side wall of the heat dissipation cover. The vertical channel formed by the supporting side plate and the heat dissipation cover has a large internal space and can accommodate more gas and dissipate heat at the same time.

[0013] Furthermore, the edge of the heat dissipation cover is sealed and connected to the supporting side plate, and the sealed connection prevents external water vapor and dust from entering.

[0014] Furthermore, the heat dissipation fins and the heat dissipation cover are integrally formed, and the integral forming process is simple, has few steps, and is low in cost. BRIEF DESCRIPTION OF THE DRAWINGS
