Another technical problem to be solved in the utility model provides a kind of light-emitting device of indicating usefulness, its light emitting diode can be done the array ordering at the hole slot form of the loophole of original screen panel, make its light luminance abundance, the light beam of the convergence that passes is clear, and can be for use as other function as modes such as indication, graticule or aimings.
A kind of light-emitting device of indicating usefulness that the utility model provides, be provided with one group of high-power light emitting diode (LED) and convergent lens group in this light-emitting device, this light emitting diode can be the light emitting diode (as: R of monochrome or polychrome mixed light, G, the trichromatic color mixing light source of B), front end in light emitting diode has installed an original screen panel, and has loophole on the original screen panel, light can be worn the convergent lens group of penetrating in the place ahead by loophole, in view of the above, with light-resource fousing is light beam, make it be projeced into object and form and to indicate the luminous point of usefulness, or to arrange in pairs or groups the routing eyeglass again and throw be an index line.
The light-emitting device of the indication usefulness that the utility model provides, loophole on the original screen panel that in this light-emitting device, installs before the light emitting diode, can form straight line loophole, parallel lines loophole, cross loophole etc., and the light emitting diode crystal is corresponding loophole array of shapes ordering.
According to as can be known above-mentioned, the light-emitting device of the utility model indication usefulness has plurality of advantages really compared to prior art, and details are as follows:
1. the utility model is indicated the light-emitting device of usefulness, by installing original screen panel with light emitting diode group front end, make light wear ejaculation by the loophole of original screen panel, hit down in the convergent lens group, utilize the convergent lens group to produce the light beam that focuses on, reach the effect that produces the light-emitting device deixis with few member.
2. with above-mentioned, the utility model is indicated the light-emitting device of usefulness, and the assembly that it constituted all meets economic benefit compared to the existing structure of utilizing the laser diode frequency conversion to produce light source on assembling and member cost.
3. the utility model is indicated the light-emitting device of usefulness, with light emitting diode as light emitting source, with the device of existing laser diode, in comparison as light emitting source, its power output is comparatively stable, mainly is that the utility model unsettled phenomenon of power of no wavelength conversion in structure produces.
4. light emitting diode of the present utility model can be done the array ordering at the hole slot form of the loophole of original screen panel, make its light luminance abundance, the light beam of the convergence that passes is clear, and can provide other function as: modes such as indication, graticule or aiming are the design of the multi-function property of tool.
