Embodiment Construction

[0027] First, see figure 2 , figure 2 A schematic diagram showing an embodiment of the light source device of the present invention, the light source device 200 has a DC power supply DC, a single control unit 201, a transformer 202, a light emitting unit 203, and a switch SW.

[0028] Wherein, the transformer 202 has a coil N1 and a coil N2, and the coil N1 and the coil N2 are arranged on the primary side and the secondary side of the transformer 202 respectively, and the coil N1 is formed by connecting a plurality of sub-coils N11-N1N in series. Correspondingly, the coil N2 It also has a plurality of sub-coils N21 to N2N.

[0029] The first end of the coil N1 is coupled to the DC power supply DC, the second end is coupled to the switch SW, one end of the sub-coils N21 ˜ N2N of the coil N2 is respectively coupled to the light emitting unit 203 , and the other end is respectively coupled to the low potential G.

[0030] In this embodiment, the control unit 101 is realized b...

Abstract

The present invention discloses a light source apparatus which utilizes the coils of a transformer to enable a single control unit to simultaneously control a plurality of groups of light emitting units so as to keep the currents in the sub-coils that are respectively coupled to the plurality of groups of light emitting units at a preset proportion. Meanwhile, output current is made more stable to enhance the usability of the light source apparatus.

Description

technical field [0001] The present invention relates to a light source device (ligjting device). The number of light sources is increased through transformer design, and the current coupled to the sub-coils of each group of light-emitting units can be adjusted to a preset ratio. Background technique [0002] Please refer to figure 1 , the general light source device 100 usually has a single direct current power supply DC and a single control unit 11, and in the case of a single control unit 11, it is used to control a single group of light-emitting units 12, so that the light-emitting units 12 generate light sources. In other words, the This light source device can only operate one group of light emitting units 12, and a single control unit 11 can only control the current on one group of light emitting units 12. [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 i...
