Embodiment 1

[0016] Embodiment one, see figure 1 , a laser lamp provided with a positioning device for multiple grating sheets, comprising a frame 1. Frame 1 is a hanger structure. The frame 1 is provided with a laser module 2 , a multi-grating sheet 11 , a motor 12 , an infrared emitting tube 13 , an infrared receiving tube 14 , an infrared shading sheet 15 and a control unit 3 .

[0017] The laser module 2 includes an LED laser tube 21 and a radiator 22 . The LED laser tube 21 is arranged horizontally. The radiator 22 is sleeved on the LED laser tube 21 for cooling the LED laser tube 21 . The radiator 22 is a horizontal cylindrical structure.

[0018] The multi-grating sheet 11 is disc-shaped. The multi-grating sheet 11 is provided with several patterns extending along the circumferential direction of the multi-grating sheet 11 . The center of the multi-grating sheet 11 is connected with the power output shaft of the motor 12 through a connecting column 16 . The motor 12 is a step...

Embodiment 2

[0020] The difference between the second embodiment and the first embodiment is that the radiator 22 is a vertical column structure. The LED laser tube 21 is vertically arranged. The light emitting section of the LED laser tube 21 faces upward. A light emitting tube 23 is connected to the radiator 22 . The light emitting tube 23 includes a vertical section 231 and a horizontal section 232 . The lower end of the vertical section 231 is butted with the radiator 22 . The scattered light collecting mirror 24 is arranged in the vertical section 231 . The scattered light collecting mirror 24 includes a circular plane lens 241 and an annular convex lens 242 surrounding the periphery of the plane lens. The centerline of the plane lens 241 coincides with the centerline of the beam emitted by the laser module, that is, the LED laser tube 21 . The scattered light collecting mirror 24 is arranged in the vertical section 231 , which can reduce the light beam scattered to the wall of t...

Abstract

The invention relates to a laser lamp, and provides a laser lamp with a multi-grating sheet positioning device. The laser lamp comprises a machine frame; a laser module, a multi-grating sheet, a motor and a control unit are arranged on the machine frame; an infrared emitting diode, an infrared receiving diode and an infrared shielding sheet are further arranged on the machine frame; and when the multi-grating sheet positioning device is started, the control unit firstly drives the motor to drive the multi-grating sheet and the infrared shielding sheet to rotate together, when the infrared shielding sheet rotates to shield light emitted by the infrared emitting diode, the control unit controls the laser module to begin to emit light, and patterns set in the multi-grating sheet are irradiated by the light emitted by the laser module. The laser lamp with the multi-grating sheet positioning device has the advantages that the projected patterns in each start-up process can be the same, and the problem that an existing multi-grating laser lamp cannot enable a projected pattern in each start-up process to be the same set pattern can be solved.

Description

technical field [0001] The invention relates to a lamp, in particular to a laser lamp provided with a positioning device for multiple grating sheets. Background technique [0002] Laser is a kind of light. With its good directionality, low power, strong penetrating power and high brightness, it is widely used in important fields such as science and technology, military, electronic pointer, navigation and ranging. In recent years, due to the improvement of people's living standards, lasers are no longer just used in military affairs and teaching, but are more and more used indoors, on the stage, in cars, etc. to set off a festive atmosphere, achieve the effect of decoration and beautify the environment. However, these lamps are expensive and have a short lifespan. In outdoor public places, neon lights are often used. Although the effect is good, the cost is high, the technical content is large, and the pattern is single. If you want to get different spots, you must replace di...
