Multi-color temperature shadowless lamp

Technical Field

The utility model relates to a shadowless lamp technical field, concretely relates to polychrome temperature shadowless lamp.

Background

A general light source is a polychromatic light obtained by mixing monochromatic lights having different wavelengths, and the term "monochromatic light" refers to a spectrum of light separated by refraction of white light or sunlight through a prism, i.e., seven colors such as red, orange, yellow, green, blue, indigo, and violet, because such a decomposed color light is not decomposed into other color lights even if it passes through the prism again. Such colored light that cannot be decomposed any more is called monochromatic light, and its wavelength is different from each other, and light having different wavelengths has different colors. In practice there are only three primary colors in optics: red, green and blue. The three colors can be mixed according to the principle of an additive method, and can be expressed by color equations such as red + green-yellow, green + blue-cyan, red + green + blue-and the like, wherein the seven colors are distinguished by the colors with different wavelengths of light waves under refraction, different colors are formed at the places where the three primary colors are mutually transited according to different proportions, and the other four colors are composed of the three primary colors. The red light is helpful for better distinguishing vascular tissues, the wound healing can be promoted by adopting the red light with the wavelength of 620nm, and the red light has a treatment effect on skin infection; green light wavelength 520 nm; blue light with a wavelength of 470nm has the effect of inhibiting inflammation.

The color temperature is a metering unit for indicating that the light contains color components, the light defined by the color temperature is not monochromatic light, the wavelength and the color temperature have no one-to-one contrast relationship, and the light is mixed light formed by mixing the monochromatic light, such as cold white light emitted by a shadowless lamp, actually consists of three primary colors, most of the conventional shadowless lamps can only emit white light and cannot emit monochromatic light such as red, green, blue and the like, but the light (light with various color temperatures) formed by combining the monochromatic light or the monochromatic light still has certain functions such as identifying textures of organs or tissues, disinfection and sterilization and the like.

The monochromatic LED lamp with multiple wavelengths is a better way for realizing multi-color temperature adjustment, and can effectively improve the defects of single function and non-adjustable color temperature of the common shadowless lamp, for example, the LED operation shadowless lamp capable of continuously adjusting color temperature mentioned in Chinese patent CN201020694844.8 adopts LED lamp panels with different luminous wavelengths to form the light source of the operation shadowless lamp, and realizes the purpose of continuously changing color temperature by adjusting the brightness of one or more LED lamp panels with different wavelengths, although the basic function of continuously adjusting color temperature is realized, the shadowless lamp has a smaller application range, does not have large-scale cold white LED lamp beads, cannot be applied to large-scale operations, adopts a brightness adjuster with excessively complex design, has a huge overall structure, does not reduce heat productivity, even needs an additional heat radiation plate for heat radiation, and needs to design a shadowless lamp with a simple structure, the adjustable shadowless lamp has the advantages that the adjustable multi-color-temperature light can be provided for small-range operations, the heating amount is small, the operation and the control are easy, and the defects that the common shadowless lamp is single in function and unadjustable in color temperature are overcome.
