Variable focal length cloud desk lamp

Abstract

The invention relates to the field of lighting, in particular to a variable focal length cloud desk lamp lighting device. The variable focal length cloud desk lamp comprises a light housing, a light source control circuit, a focal length varying device, heat dissipation equipment and a double-axis cloud. The variable focal length cloud desk lamp realizes a variable focal length structure with an adjustable beam angle by changing a distance between an LED light source and a lens; the complicated structure of the variable focal length structure is simplified; the focal length is adjusted by adopting a stepping motor, so that the focal length is varied more accurately; a duct type integral structure is adopted, a light-weight aluminum alloy LED lamp bead support is arranged inside the duct type integral structure, so that the heat dissipation property of the integral structure is greatly improved; the variable focal length cloud desk lamp lighting device intelligently follows the rotation, namely light moves with the movement of a cloud camera, so as to capture clearer night environment information; by remote wireless control, the levelness and the pitching angle of the equipment canbe adjusted.

Description

technical field [0001] The invention relates to the lighting field, in particular to a zoom pan table lamp lighting device. Background technique [0002] Due to the special light conditions at night, the application of lighting in various fields has become essential. With the in-depth application of drones, by installing lighting equipment on the fuselage of drones, it is convenient for lighting at night, improving the work efficiency of night operations, and getting rid of the problems of limited height of traditional lighting and inflexible control methods. In the process of emergency repair of power system lines at night, due to the relatively dense lines in some areas, it is necessary to supplement the light at the maintenance parts in a weak light environment, so as to facilitate the maintenance of the staff. However, the lighting beam angle of traditional lighting fixtures is a fixed value, and the lighting effect is not good at certain distances. The lighting source...

Problems solved by technology

[0005] In order to solve the technical problems in the prior art that the lamp cannot be remotely controlled to zoom, the pitch angle cannot be adjusted, the intelligent follow-up with the pan-tilt camera cannot be realized, and the heat dissipation speed is slow, etc., the present invention discloses a zoom pan-stand lamp, which can change the distance between the LED light source and the lens. The distance between them realizes the zoom structure with adjustable beam angle. At the same time, the present invention adopts a ducted overall structure, and the interior is a light aluminum alloy LED lamp bead support, which greatly improves the heat dissipation performance of the overall structure.
