Three-wire double-color COB lamp strip

Abstract

The invention discloses a three-wire double-color COB lamp strip which comprises a plurality of lamp strip units connected in parallel, each lamp strip unit comprises a flexible circuit board, a plurality of warm white light LED chips connected in series are arranged on the left side of the top of each flexible circuit board, and a plurality of white light LED chips connected in series are arranged on the right side of the top of each flexible circuit board. The warm white light LED chips and the white light LED chips are vertically arranged in two rows in the shape of a Chinese character'pin ', the upper surface of the flexible circuit board is provided with 2400K color temperature fluorescent powder colloid covering the white light LED chips, and the upper surface of the flexible circuit board is provided with 6500K color temperature fluorescent powder colloid covering the warm white light LED chips. And the 6500K color temperature fluorescent powder colloid is coated on the outer side of the 2400K color temperature fluorescent powder colloid. The LED lamp is large in emitting color adjustable amplitude, high in color adjustment precision, good in light mixing effect, uniform in emitting light, free of glare and convenient to use.

Description

technical field [0001] The invention relates to the technical field of light strips, in particular to a three-wire and two-color COB light strip. Background technique [0002] COB light strip is a new type of high-brightness and high-definition linear lighting strip. It has exquisite appearance, soft light, no light spot, good waterproof performance, adopts flip-chip packaging technology, good heat dissipation and long service life. The COB light strips on the existing market are generally monochromatic. The luminance and color of the COB light strips of the light strips are adjusted through the driver, but the color accuracy of the adjustment is not high, and the color adjustment is limited. The two-color three-line LED on the market The lamp beads of the light strip are arranged side by side. Because there is a gap in the middle of the two-color arrangement, the color mixing effect of the two-color light is not ideal when emitting light. The LED lamp beads arranged in gaps...

AI Technical Summary

Problems solved by technology

The COB light strips on the existing market are generally monochromatic. The luminance and color of the COB light strips of the light strips are adjusted through the driver, but the color accuracy of the adjustment is not high, and the color adjustment is limited. The two-color three-line LED on the market The lamp beads of the light strip are arranged side by side. Because there is a gap in the middle of the two-color arrangement, the color mixing effect of the two-color light is not ideal when emitting light. The LED lamp beads arranged in gaps will inevitably appear dark areas during lighting, which cannot meet customer requirements. At the same time, the existing The COB light strip still has insufficient uniformity of light emission, impure monochromatic light, and unsatisfactory two-color mixed light effect
