Abstract
The utility model relates to a separated quartz lamp light regulation power-supply box. A light regulation power-supply box and a quartz lamp are two independent parts, the light regulation power-supply box is provided with a plurality of groups of identical light regulation control circuits, the output power supply of each group of light regulation control circuits respectively controls the quartz lamp by conducting wires, and the brightness of each quartz lamp can be regulated at the same time in situ. The utility model has the advantage of convenient operation, and is very suitable for the occasions, such as indoor photograph, shooting, movie shooting, etc.
Description
The utility model relates to a kind of power supply box, specifically about a kind of quartz lamp light modulation power supply box.Light power when the utility model is applicable to photography, shooting, film shooting is regulated.
Existing quartz lamp dimmer is to be connected in series bidirectional triode thyristor in the quartz lamp power supply, control the operating voltage of quartz lamp by the angle of flow of regulating bidirectional triode thyristor, its adjusting control circuit and quartz bulb dress are one, be installed on the lamp bracket simultaneously, the shortcoming of this structure is: lamplight brightness will arrive the lamp bracket adjusted, need regulate the brightness of every light during photography back and forth, troublesome poeration.
The purpose of this utility model is a kind of quartz lamp light modulation power supply box that can regulate on-the-spot every lamplight brightness at same position of design.
The technical solution of the utility model comprises light modulation power supply box and quartz lamp, its light modulation power supply box and quartz lamp are independently two parts of difference, a group or more identical adjusting control circuit is arranged in a light modulation power supply box, and the power output interface of every group of adjusting control circuit is respectively by lead and different quartz lamp connections.
The utility model beneficial effect compared with prior art is many quartz lamps of a light modulation power supply box may command, and the light modulation power supply box arbitrarily can be moved, and the operator can regulate the brightness of each quartz lamp in the original place, uses flexible, convenient.
Fig. 1 is the schematic diagram of the split type quartz lamp light modulation of the utility model power supply box.
Now in conjunction with the accompanying drawings and embodiments the utility model is further described.Light modulation power supply box 1 of the present utility model and quartz lamp 2 are two independent parts, and light modulation power supply box 1 comprises casing, panel, adjusting control circuit, power input interface 3 and power output interface 4.Its adjusting control circuit is made up of the controllable silicon of connecting with bulb and silicon controlled trigger signal control circuit and switch, indicator light, fuse, and wherein switch, indicator light, fuse and silicon controlled trigger signal are regulated button and be installed on the panel.A group or more identical adjusting control circuit of dress in the casing, every group of adjusting control circuit all has a power output interface 4, and be connected with quartz lamp by lead respectively, respectively organize silicon controlled trigger signal adjusting button, the brightness of the quartz lamp that control is connected with this group by regulating.
Claims (1)
