Compact light source switching device

Abstract

The invention provides a compact light source switching device. The compact light source switching device comprises a base, a switching ring, a pulling rope, a heat sink and light sources, wherein a groove is formed in the base; the switching ring can rotate around the base; the pulling rope is connected to the two ends of the heat sink and fastened to the switching ring; and the heat sink is provided with the light sources and light transmission holes, can be provided with the multiple light sources or the multiple light source light transmission holes or can be provided with the multiple light sources and the multiple light source light transmission holes at the same time. The switching ring is rotated and drives the pulling rope to move, and the pulling rope drives the heat sink to slide, so that switching of the light sources is achieved. The compact light source switching device is compact in structure, reasonable in design, easy to assemble, convenient to realize, small in size and low in weight; the double-light-source switching function is achieved, and integration of various light source emitting mechanisms is also achieved; and the compact light source switching device is low in realizing cost, convenient and rapid in light source switching, long in service life, high in practicability and easy to apply and popularize.

Description

technical field [0001] The invention belongs to the field of optomechanical technology, and in particular relates to a compact light source switching device. Background technique [0002] Now the common light emitting equipment is mostly a single light source. Equipment with a single light source can no longer meet the needs of some special markets. For example, when on duty or hunting at night, green light and white light need to be used together. Most of the existing equipment on the market can only emit a single light source; a small number of switching devices with dual light sources are switched by different LEDs to emit no light source, and no device that can switch between LED light source and laser light source has been found. [0003] Most of the existing light source switching mechanisms have a rotating mechanism and use the cam principle to realize the switching, which makes the switching mechanism large in size, complicated in machining, and heavy, which is not ...

Problems solved by technology

Most of the existing equipment on the market can only emit a single light source; a small number of switching devices with dual light sources are switched by different LEDs to emit no light source, and no device that can switch between LED light source and laser light source has been found.

[0003] Most of the existing light source switching mechanisms have a rotating mechanism, which uses the cam principle to achieve switching, which makes the switching mechanism large in size, complicated in machining, and relatively heavy, which is not suitable for the requirements of light portable equipment.
