Abstract

The invention discloses a light-emitting diode (LED) mixed color lamp. The LED mixed color lamp comprises a lamp holder, a lamp bead board radiating seat and a back cover, wherein an accommodating room is formed on the upper end part of the lamp bead board radiating seat; a substrate is arranged in the accommodating room; a condenser lens installation board is arranged in front of the substrate; a zoom lens installation board is arranged in front of the condenser lens installation board; more than one condenser lens is arranged on the condenser lens installation board; zoom lenses with the same number as the condenser lenses are arranged on the zoom lens installation board; the zoom lenses correspond to the condenser lenses at front and back positions; the light emergent surface of each condenser lens is provided with a first micro lens group which consists of more than two first micro lenses; each zoom lens comprises a zoom lens body and a second micro lens group which is arranged onthe zoom lens body; the second micro lens group consists of second micro lenses; and the second micro lenses have the same number as the first micro lenses on the condenser lens and correspond to thefirst micro lenses. The LED mixed color lamp has high light spot color uniformity.

Description

technical field [0001] The invention relates to an LED lamp, especially an LED color mixing lamp. Background technique [0002] Due to the advantages of rich colors, long life, high luminous efficiency, energy saving and environmental protection, LED lights are widely used in daily life and stage performances. Since LED chips are mainly red, blue and green, in practical applications, in order to obtain a certain color of light, light mixing is usually required. The light mixing method currently used is generally physical light mixing, that is: such as figure 1 As shown, LED chips of different colors are installed on the substrate in the lamp, and the LED chip has a certain emission angle when emitting light. Therefore, the light emitted by the LED chip alone will be mixed with the light of the adjacent LED chip in front to achieve mixing. light purposes, however, as figure 1 As shown, due to the limited emission angle of the LED chip, there is only one color of light at t...
