Refraction type shadowless operating lamp

Abstract

The invention discloses a refraction type shadowless operating lamp which is characterized by comprising a plurality of light source assemblies and a refractor. The light source assemblies use LEDs as light sources and are annularly disposed along the inner side of the edge of a lamp shell. The light source assemblies concentrate the light of the LEDs into linear light beams to be refracted into the refractor, and the light beams are refracted by the refractor to form a shadowless lighting area A. The refractor is an integral lens medium, the central part of the refractor extends outwardly to form an arc-shaped structure, an inner arc surface and an outer arc surface are formed, the inner arc surface and the outer arc surface are of a trapezoid structure, or the inner arc surface is of a trapezoid structure, and the lens medium of the refractor is transparent or semi-transparent. The refraction type shadowless operating lamp is good in radiating performance, high in lighting effect utilization rate, low in LED light attenuation, and the like.

Description

technical field [0001] The invention relates to a surgical lamp, in particular to a refraction type shadowless surgical lamp with multiple refractions. Background technique [0002] In the prior art, the LED shadowless lights used in hospital operating rooms all use the arrangement of multiple LED light sources in the form of gypsophila and directly illuminate the operating area. The heat is large, and the heat dissipation of the lamp is slow, which aggravates the attenuation of light, affects the lighting effect and service life of the shadowless lamp, how to ensure the good heat dissipation of the shadowless surgical lamp, and manufactures a light source assembly with a combination of LED and lens. way, it is arranged inside the edge of the lamp housing between the lamp body and the lamp housing, and is oriented to the refraction surface of the lamp body. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a refraction type shadowless su...

Problems solved by technology

[0002] In the prior art, the LED shadowless lamps used in hospital operating rooms are all arranged in the form of multiple LED light sources in the form of stars and directly irradiated to the operation area. The heat is large, and the heat dissipation of the lamp is slow, which intensifies the attenuation of light and affects the lighting effect and service life of the shadowless lamp. How to ensure good heat dissipation of the shadowless surgical lamp, for this purpose, a light source assembly with a combination of LED and lens is manufactured, using refracted light way, it is arranged inside the edge of the lamp housing between the lamp body and the lamp housing, and is oriented to the refraction surface of the lamp body
