Embodiment Construction

[0028] First, see figure 1 , figure 1 It is a schematic diagram showing an embodiment of the light source device of the present invention. The light source device 100 has a single control unit 101 , a transformer 102 , and a light emitting unit 103 . The transformer 102 has a coil N1 and a coil N2, the coil N1 and the coil N2 are respectively arranged on the primary side and the secondary side of the transformer 102, and a filter 104 is connected in series between the control unit 101 and the primary side of the transformer 102, the filter 104 It can be realized by a capacitor. The coil N1 is coupled to the control unit 101 , and the first end and the second end of the coil N2 are respectively coupled to the light emitting unit 103 . In addition, the control unit 101 can also be realized by an integrated circuit IC (Integrated Circuit, IC).

[0029] The light emitting unit 103 is composed of a plurality of light emitting diodes 106. In this embodiment, the light emitting di...

Abstract

The invention discloses a light source device comprising a single control unit, at least one transformer, two groups of light-emitting units, at least four rectifying diodes and at least two capacitors, wherein the single control unit is used for generating a control voltage according to at least one signal; the at least one transformer is coupled with the control unit; the two groups of light-emitting units are respectively a plurality of serially-connected light-emitting diodes and are coupled with the transformer for generating light; the transformer comprises a first coil and a second coil; the first coil is coupled with the second coil according to the control voltage to generate a coupling voltage at the second coil; and two ends of the second coil are respectively coupled to two rectifying diodes and one capacitor, are used for rectifying the coupling voltage to form a direct current signal and outputting the direct current signal from two ends of the second coil so as to drive the light-emitting diodes. By using the coils of the transformer and various connecting modes, the single control unit can simultaneously control various groups of light-emitting units through the transformer.

Description

technical field [0001] The present invention relates to a light source device, in particular to a light source device that increases the number of light sources through transformer design. 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. However, in this way, not only the use of the circuit area is greatly increased, but also the volume increases, causing inconvenience to the use...
