Document Type and Number:
WIPO Patent Application WO/2020/077894
Kind Code:
A1
Abstract:
A small-angle multicolor light-mixing illumination system, comprising a radiator (7), a housing (5), multicolor lamp beads (61), and a lens (4). The radiator (7) and the lens (4) are respectively mounted at the bottom and the top of the housing (5), the multicolor lamp beads (61) are fixed on a circuit board (62), the circuit board (62) is fixed on the radiator (7), and the multicolor lamp beads (61) and the lens (4) are all located inside the housing (5); the multicolor lamp beads are multicolor LED lamp beads; an optical waveguide column (1) is further comprised, the optical waveguide column (1) is a light-transmitting column body, the optical waveguide column (1) is fixed at the top of the radiator (7) and is positioned between the multicolor lamp beads (61) and the lens (4), and the optical waveguide column (1), the lens (4), and the multicolor lamp beads (61) are provided coaxially. The optical waveguide column (1) is good in light mixing effect and can achieve mixing of various monochromatic light. The small-angle multicolor light-mixing illumination system is small in light emitting angle, long in range, small in light spot, high in brightness, and convenient to combine and use.
