Embodiment Construction

[0018] Spectrum diagrams of white light with cooler tones and warmer tones according to the present invention are shown in Figures 1 and 2, so the white light formed after the two are mixed is evenly changed in the spectrum, covering all visible areas of human vision. Panchromatic light thus obtains full-color natural display. The visual color reduction degree of objects in the illuminated working area is Ra>93, and the color temperature is about 4500K. It can be adjusted according to needs, which is beneficial to relieve visual fatigue and improve surgical accuracy.

[0019] Fig. 3 is a light-emitting module according to an embodiment of the present invention, which includes white light emitter LEDs 101 to 106 uniformly distributed in a ring shape on the base 3 and partial LEDs evenly distributed among the white light emitter LEDs with cold tone. Warm-toned white LEDs 201 to 213, this arrangement enables the light emitted by the two to mix uniformly in space. The white illumi...

Abstract

The invention relates to an operating-lamp which can adjust the color temperature. It is made up of a white light luminous series which is cold color, the white light luminous series which is warm color and a controller to adjust the luminous intensity. So the operating-lamp has the uniform light spectrum change, the color temperature and the light intensity can be adjusted, also it has the simple structure and easy operation.

Description

technical field [0001] The invention relates to an operation lamp with adjustable color temperature. Background technique [0002] At present, in order to solve the lighting problem in the operation process, most people use shadowless lamps. Early shadowless lamps were mainly composed of single or multiple incandescent bulbs or fluorescent tubes placed in a conical lampshade coated with reflective film. When in use, after all incandescent lamps or fluorescent lamps are turned on, the visible light emitted by them is directly or reflected by the lampshade and shoots to the working surface of the operating light. But this kind of surgical lamp is because its light source is incandescent lamp or fluorescent lamp, and the color temperature of incandescent lamp is low and high energy consumption, and the light that sends contains a large amount of infrared rays, and lamp body needs to dissipate heat forcibly; The light emitted contains a lot of ultraviolet rays that are harmful...
