Light source device

Abstract

The invention discloses a light source device which is characterized in that a positive voltage source and a negative voltage source are utilized to generate a positive voltage and a negative voltage, and the positive voltage and the negative voltage are coupled to a light-emitting unit so as to emit light. In the invention, a transformer is utilized, so that a single control unit can controls a plurality of groups of light-emitting units simultaneously, and the problem that the single control unit only can control the single group of light-emitting units is solved; and the voltage difference between the positive voltage and the negative voltage is utilized to improve the whole efficiency of the light source device.

Description

technical field [0001] The present invention relates to a light source device, in particular to a light source device that improves the conversion efficiency and the number of light-emitting units through the design of a negative voltage source and a transformer. Background technique [0002] A general light source device usually has a single control unit, and in the case of a single control unit, it is used to control a single group of light-emitting units to make the light-emitting units generate light. [0003] Therefore, in order to meet the needs of use, if you want to operate multiple groups of light-emitting devices at the same time, the general method is to increase the number of control units correspondingly, so that the number of control units is the same as the number of groups of light-emitting units, so that one control unit can control a group of light-emitting devices correspondingly. unit, but in this way, not only greatly increases the use of the circuit are...

Problems solved by technology

[0002] A general light source device usually has a single control unit, and in the case of a single control unit, it is used to control a single group of light-emitting units to make the light-emitting units generate light. In other words, this kind of light source device can only operate a group of light-emitting units

[0003] Therefore, in order to meet the needs of use, if you want to operate multiple groups of light-emitting devices at the same time, the general method is to increase the number of control units correspondingly, so that the number of control units is the same as the number of groups of light-emitting units, so that one control unit can control a group of light-emitting devices correspondingly. Unit, but in this way, not only greatly increase the use of circuit area, but also cause inconvenience to users when the volume increases, and also increase production costs

[0004] In addition, general light source devices usually have poor conversion efficiency when providing power to the light emitting unit, resulting in unnecessary power consumption
