Operation astral lamp using LED as light source

Abstract

The invention relates to a medical appliance of a surgical shadowless lamp, in particular to a surgical shadowless lamp using LEDs as a light source. The surgical shadowless lamp comprises a light source reference plate with a pointolite cardinal plane; a plurality of LEDs are arranged on the pointolite cardinal plane; the shadowless lamp also comprises a lens reference plate is provided with a plurality of lenses embedded in a lens cardinal plane; each lens corresponds to each LED on the pointolite cardinal plane; the lens cardinal plane is parallel to the pointolite cardinal plane; the distance between the lens cardinal plane and the pointolite cardinal plane is between 8 and 40 mm; the lenses are converging convex lens, and have the same specification. The surgical shadowless lamp mainly solves the problems that the structure of the prior product makes LED light sources project on the equidistant plane faculae with different diameters and consequently influences the distribution of faculas, lighting depth and other indexes; and the surgical shadowless lamp has the advantages of high illumination, low energy consumption, long service life, low irradiation, environmental protection and the like; in addition, the surgical shadowless lamp has good social and economic benefits and wide market prospect.

Description

technical field [0001] The invention relates to a surgical shadowless lamp for medical equipment, in particular to a surgical shadowless lamp using LED as a light source. Background technique [0002] At present, LEDs have been used as light sources for surgical shadowless lamps. LEDs use electron movement to emit light, and directly convert electrical energy into light energy. The conversion efficiency is as high as 68%, which is more than 5 times that of incandescent bulbs. Compared with the commonly used tungsten-halogen bulbs, using LEDs as the light source of shadowless lamps has many advantages: First, the LED is a real cold light source, and its radiant energy is much lower than that of tungsten-halogen bulbs under the same illuminance That is to say, when the surgical shadowless lamp using LED as the light source is used for surgical lighting, it will not damage human body tissue at all; second, the heat loss of LED is very low, and the power conversion efficiency is...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is a surgical shadowless lamp using LED as a light source, which mainly solves the problem that the structure of existing products makes the spot diameters formed by each LED light source projected onto a fixed-distance plane to be inconsistent, which affects the spot distribution and illumination depth and other indicators. The problem is that it has the advantages of high illumination, low energy consumption, long life, low radiation, environmental protection, etc., has good social and economic benefits, and has broad market prospects.
