Small-angle multicolor light-mixing lighting system

Abstract

The invention relates to a landscape lighting device, in particular to a small-angle multicolor light-mixing lighting system. The small-angle multicolor light-mixing lighting system comprises a radiator, a shell, multicolor lamp beads and a lens, wherein the radiator and the lens are arranged at the bottom and the top of the shell respectively, the multicolor lamp beads are fixed on a circuit board, the circuit board is fixed on the radiator, and the multicolor lamp beads and the lenses are located inside the shell; the multicolor lamp beads are multicolor LED lamp beads; and the small-angle multicolor light-mixing lighting system further comprises an optical waveguide column, wherein the optical waveguide column is a light transmitting column body, the optical waveguide column is fixed atthe top of the radiator, and is positioned between the multicolor lamp beads and the lens, and the optical waveguide column, the lens and the multicolor lamp beads are arranged coaxially. According to the small-angle multicolor light-mixing lighting system, the optical waveguide column is good in light mixing effect and can be used for mixing various monochromatic light; and the small-angle multicolor light-mixing lighting system is small in light emitting angle, long in range, small in light spot, high in brightness and convenient to combine and use.

Description

technical field [0001] The invention relates to a landscape lighting device, in particular to a small-angle multi-color mixed light lighting system. Background technique [0002] At present, floodlights, wall washers and landscape lights on the market all use light mixing lenses, which use the principle of light refraction and light concentration to mix light. Due to the limitations of its optical principle, the light mixing lens cannot irradiate light at a small angle after mixing light. The light mixing lens on the market has a minimum light angle of 15 degrees, and the light mixing effect is also poor. The irradiation distance is usually 3 to 5 meters, the light spot is large, the light diverges sharply, and the brightness is low. Contents of the invention [0003] In order to solve the above problems, the present invention provides a small-angle multi-color mixed light lighting system with a small emission angle and a long irradiation distance. The specific technical ...
