Problems solved by technology

In this adjustable color temperature control system, since the voltage directions of the two groups of cool-color and warm-color LED lamps are consistent, in order to supply power to the LED lamp group 4, a power line must be used to control the cool-color LED lamp D1- The control line for the working state of Dn, a control line for controlling the working state of the warm-color LED lamp Dn+1-D2n, this wiring requirement will lead to a relatively high overall cost of the lamp, and also increases the difficulty of layout of the lamp circuit , is also not conducive to the control of the size of the lamp structure

Abstract

An LED lamp control system comprises two signal generating modules, two signal control modules and an LED lamp set. The signal control modules control voltage directions at the two ends of the LED lamp set respectively according to control signals of the signal generating modules. The LED lamp set comprises at least one first LED lamp set body and at least one second LED lamp set body, wherein the break-over voltage of the first LED lamp set bodies is opposite to the break-over voltage of the second LED lamp set bodies. The first LED lamp set bodies and the second LED lamp set bodies are switched between turn-on and turn-off according to the voltage directions at the two ends of the LED lamp set. The LED lamp set of the LED lamp control system enables the break-over voltage direction of the first LED lamp set bodies to be opposite to the break-over voltage direction of the second LED lamp set bodies, the first LED lamp set bodies and the second LED lamp set bodies are connected in parallel, therefore, by the utilization of the control signals output by the two signal generating modules and compiling of the control signals through the signal control modules, turn-on and turn-off switching of the first LED lamp set bodies and the second LED lamp set bodies can be achieved by only using two wires, reduction of connecting wires is achieved, the cost and the typesetting difficulty are reduced easily, and meanwhile, the lamp structure is reduced.

Description

technical field [0001] The invention relates to a power supply device, in particular to an LED lamp control system with adjustable color temperature. Background technique [0002] With the concept of "humanized lighting" deeply rooted in the hearts of the people, lighting design should create a good indoor lighting effect to meet people's physiological and psychological requirements. The color temperature is an important factor in lighting design. Different color temperatures give people different feelings and can meet the needs of different people. Therefore, in some lamps, the above purpose is achieved by dimming the warm and cool colors of the lamps. The existing control system with adjustable color temperature is composed of a power supply, a controller, and a lamp with adjustable color temperature. A lamp with adjustable color temperature usually consists of two sets of cool-color and warm-color LED lights arranged at intervals, and the voltage directions of the two s...
