Problems solved by technology

When incandescent lamps work directly on AC mains, the stroboscopic phenomenon is more serious; due to the excitation characteristics of fluorescent light emitters, there are also stroboscopic defects. Although this defect can be overcome by increasing the operating frequency and other technologies, the theoretical stroboscopic
There are a small number of desk lamps using light-emitting diodes as illuminants, but a single white light-emitting diode is generally used. Although this type of desk lamp solves the flickering defect of incandescent or fluorescent lamps, the color spectrum is not rich and too single. Sex is not strong

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and examples, but the examples should not be construed as limiting the present invention.

[0023] The R-LED matrix of the lamp panel of the present invention is composed of R light-emitting tubes D1-D84, the G-LED matrix is ​​composed of G light-emitting tubes D101-D184, and the B-LED matrix is ​​composed of B light-emitting tubes D201-D284. connected to the negative pole of the power supply, and the positive poles of each matrix are respectively connected to the output terminals of the three switching circuits in the control circuit ( figure 2 ).

[0024] The central control unit U1 of the present invention is a control IC ( image 3 ), relying on internal procedures to work. U2 is the SPROM memory ( Figure 4 ), used to save the current working state and other data, the central control unit U1 can read and write data to it, and the data transfer between the central...

Abstract

This invention relates to one composite color LED lamp composed of light board and control circuit, wherein, the lamp board is composed of at least one set of LED light tubes and the invention is characterized by the following: each set of LED light tubes are composed of red light tube, green light tube, blue light tube; at least one R tube, G tube ad B tube form one single LED matrix; the control circuit output can adjust direct flow voltage to control each single LED matrix to complete eliminate the flash.

Description

technical field [0001] The invention belongs to a lighting tool, in particular to a full-color LED desk lamp using a light emitting diode as a light source. Background technique [0002] At present, what the desk lamp on the market generally uses is that incandescent lamp or fluorescent lamp are as illuminant. When incandescent lamps work directly on AC mains, the stroboscopic phenomenon is more serious; due to the excitation characteristics of fluorescent light emitters, there are also stroboscopic defects. Although this defect can be overcome by increasing the operating frequency and other technologies, the theoretical The flickering still exists. There are a small number of desk lamps using light-emitting diodes as illuminants, but a single white light-emitting diode is generally used. Although this type of desk lamp solves the flickering defect of incandescent or fluorescent lamps, the color spectrum is not rich and too single. Sex is not strong...
