[0025] This embodiment provides a beam expanding laser lamp with a double-mirror scanning structure, such as figure 1 with figure 2 As shown, it includes a laser light box body 1, the side of the laser light box body 1 is a light outlet 2, and the light outlet 2 is connected to a beam expander 3, and the beam expander 3 is connected to a double-mirror scanning structure. The laser beam emitted from the light outlet 2 of the light box body 1 is expanded by the beam expander 3 to reach a diameter of 20 mm to 30 mm, and the expanded coarse beam is scanned by a double-mirror scanning structure before being emitted.

[0026] Specifically, the laser light in the laser light box 1 is emitted to the beam expander 3 through the light outlet 2, and the thin beam (3mm-6mm) is expanded into a coarse beam (20mm-30mm) through the beam expander. The beam is scanned and emitted.

[0027] In particular, the diameter of the beam projected by a conventional laser lamp is about 3 to 6mm. When ...

[0033] refer to figure 1 , in order to facilitate the installation and support of the reflector 10, an L-shaped plate 11 is installed on the bottom plate of the housing 4, the horizontal plate of the L-shaped plate 11 is closely fixed on the bottom plate of the housing 4, and the vertical plate of the L-shaped plate 11 The plate is perpendicular to the bottom plate of the housing 4, and the reflector 10 is closely mounted on the vertical plate. The optical path of the reflector 10 is as follows: the coarse beam emitted by the beam expander 3 enters the reflector 10 and passes through the reflector 10. The optical path of the rough beam is changed so that the rough beam emitted by the mirror 10 and the rough beam incident on the mirror 10 form an angle of 90° and are parallel to the bottom plate of the housing 4 .

Abstract

The invention provides a beam expanding laser lamp with a double-lens scanning structure. The lamp comprises a laser lamp box, wherein the side surface of the laser lamp box is provided with a light outlet, and the light outlet is connected with a beam expander; the beam expander is connected with a double-lens scanning structure, the diameter of laser emitted from the light outlet of the laser lamp box body reaches 20mm-30mm after the laser is expanded by the beam expander, and a thick light beam after beam expansion is scanned by the double-lens scanning structure and then is emitted out. According to the beam expanding laser lamp with the double-lens scanning structure provided by the invention, firstly, the laser beam is expanded to be about 20mm-30mm in diameter by adopting the beam expanding lens so as to be thicker, so the laser beam has better visual impact force, and the performance effect is better; and then the expanded thick light beam is scanned through a double-lens scanning structure, namely a scanning galvanometer, so the laser beam performance is more dynamic.

Description

technical field [0001] The invention belongs to the technical field of laser lamps, and in particular relates to an expanded beam laser lamp with a double mirror scanning structure. Background technique [0002] Because the laser light emitted by the laser light has a special lighting effect, and it can form text, patterns, and animation effects when combined with dry ice smoke, etc., so the laser light is often used in the performance of large-scale events such as evening parties. [0003] The diameter of the beam projected by conventional laser lights is about 3-6mm. It works well when projecting animated text, but when it is necessary to project laser beams, it will appear that the beam is too thin and the visual impact is slightly poor. In addition, the scanning system commonly used in laser lights currently has a lens size of 9*16mm, which cannot be used in laser beam lights with a laser beam diameter of 20-30mm. Contents of the invention [0004] The purpose of the ...
