Has the advantages that: the projection shape of the light spot is in a circular projection shape, the light rays are projected and scattered to form an angle of 10 degrees, and the light rays are projected in a concentrated mode; the illumination projection is uniform, and the light color can be changed by changing the LED lamp wicks with different colors; low energy consumption, small volume, long service life and low maintenance cost.

Description

Concentrating lens of a 4-bead combined LED floodlight

technical field

The utility model relates to a lens for an LED lamp, in particular to a condensing lens for a 4-bead combined type LED projection lamp. The so-called 4-bead combination refers to a light-emitting unit composed of 4 light-emitting diodes (agreed below). the

Background technique

At present, lighting is usually carried out on landscapes such as building outlines, squares, parks, communities and various tourist attractions. In order to beautify the environment, render the atmosphere and effect of landscape lighting, traditional lamps are commonly used, such as incandescent lamps, fluorescent lamps, high-pressure mercury lamps, metal halide lamps, high-pressure sodium lamps and low-pressure sodium lamps, etc. The main disadvantages of such lamps are Short service life, low light efficiency, high energy consumption, difficult light color control, large volume and high maintenance costs. There is still a certain gap between this and the country's requirements for promoting energy conservation and emission reduction. the
