Color-temperature-adjustable high-color-rendering white light system and imaging equipment

Abstract

The invention provides a color-temperature-adjustable high-color-rendering white light system and imaging equipment. The white light system comprises five sets of lamp beads, wherein the five sets oflamp beads are mixed according to a fixed proportion to obtain white light. The white light imaging equipment comprises a lamp bead plate, a collecting lens set, a light combining lens set, an imaginglight hole and an imaging lens set; the lamp bead plate comprises five sets of lamp beads, and the five sets of lamp beads are mixed according to a fixed proportion to obtain white light; the collecting lens set focuses the light of the beads to be within 20 degrees; the light combining lens set further combines the light; the light is combined to the imaging light hole; and the imaging lens setimages the imaging light hole. According to the system and the equipment, the lamp beads are mixed according to the fixed proportion, the white light with high color rendering property and variable color temperature is obtained on the premise of low light source power density and simple heat dissipation, and a color effect is achieved.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to a high color rendering white light system with adjustable color temperature and an imaging device. Background technique [0002] At present, high-quality white light on the market generally uses COB (Chip On Board, high-power integrated surface) light source, which can achieve Ra (color rendering index) above 95 and R9 (the ninth special color rendering index) above 95. However, the COB light source has high power density and high heat dissipation requirements. The color temperature of the COB light source cannot be changed. If different color temperatures are required, more lamps are required, which increases the application cost. Therefore, under the premise of low light source power density and simple heat dissipation, obtaining white light with high color rendering, variable color temperature, and color effect has become a technical problem that needs to be solved at presen...
