Problems solved by technology

These dimming power supply modules are designed for traditional professional lighting power supply systems. The modules cannot be connected in series, which cannot meet the needs of the next generation of professional lighting power supply systems to flexibly build regional power distribution networks.
[0005] On the other hand, the current dimming power supply module must provide a separate power supply (single-phase and three-phase can be used, manufacturers recommend using three-phase power supply), one power supply can only be used by a group of dimming modules, the existing dimming The optical power supply module has a maximum of 8 channels, which means that a group of power supplies can only be used by 8 lamps at most. In actual engineering, these independent power lines are a considerable number
[0006] In addition, what is more serious is that the current air switch on these dimming power supply modules is manual. Once the dimmer (silicon block) inside the module is broken down, the dimming power supply module may be set at any position on the stage. In most cases, the staff cannot reach the position of the module in time to manually turn off the air switch, so that during the performance, the lamp corresponding to the damaged dimmer remains always on, resulting in a performance accident
During the performance, individual lamps are allowed to be constantly off, but individual lamps are never allowed to be constantly on. If the lamps are not controlled and always on, this is a performance accident during the performance and is absolutely unacceptable
[0007] Furthermore, most of the existing dimming power supply modules are 2, 4, or 8 channels. Although a three-phase power supply is used, it is difficult to achieve three-phase balance
There is no leakage protection switch in all circuit units, which poses a safety hazard

Embodiment 1

[0058] Such as Figure 1 to Figure 3 As shown, this embodiment provides a dimming power supply module. The dimming power supply module includes: a housing (not shown in the figure), several cables placed in the housing, set on the housing and respectively connected to two ends of the several cables. The first connector 16 and the second connector 17, the interface unit, and a set of dimming socket assemblies, the dimming socket assembly includes lamp sockets 61, 62, 63 connected to several cables to supply power to lamps, The dimmer 52 and the control unit 40 for performing dimming control on the dimmer 52 according to the control signal received by the interface unit.

[0059] The types of the above-mentioned first connector and the second connector are male socket or female socket, and the first connector and the second connector may adopt the same type of socket or different types of sockets. This makes it possible to connect different dimming power supply modules through ...

Embodiment 2

[0076] This embodiment provides a dimming power supply module. The difference between this embodiment and Embodiment 1 is that the interface unit of this embodiment receives data containing / encapsulating DMX data packets through the network signal input interface 33 . Such as Figure 7 Shown is a receptacle power module with a phase A lamp receptacle 61, as Figure 8 Shown is a receptacle power module with phase B lamp receptacle 62, as Figure 9 Shown is a socket power supply module with a C-phase lamp socket 63, all of which use the network signal input interface 33 to receive external control signals.

[0077] In addition, the dimming power supply module of this embodiment also includes a DMX network decoding module 34 for decoding and converting data containing / encapsulating DMX data packets into DMX data packets. The network decoding module can be integrated into the interface unit or control unit, or Independent of interface unit and control unit. Such as Figure 10 ...

Embodiment 3

[0086] Such as Figure 13 , Figure 14 As shown, this embodiment provides a dimming power supply module, the dimming power supply module includes: a housing (not shown in the figure), a number of cables placed in the housing, arranged on the housing and connected to two The first connector 16 and the second connector 17 at the end, the interface unit, and two or more groups of dimming socket assemblies, each group of dimming socket assemblies includes lamp sockets 61, 62, 63. The dimmer 52 connected to the lamp socket and the control unit 40 for dimming and controlling the dimmer according to the control signal received by the interface unit.

[0087] Since the dimming power supply module of this embodiment is provided with a first connector and a second connector, two groups of dimming power supply modules can be connected in series through connection cables with male plugs and female plugs at both ends. The female plug of the connection cable is mated with the first connec...

Abstract

The invention relates to the technology of stage, movie and television lighting, and in particular relates to a light-regulating power supply module used for a professional light power supply system and a control method thereof. The module comprises a shell, a plurality of cables arranged in the shell, a first connector and a second connector which are arranged on the shell and are respectively connected with the two ends of the plurality of cables, an interface unit and at least one light-regulating socket assembly, wherein each set of the light-regulating socket assembly comprises a lamp socket connected with the plurality of cables to supply power to a lamp, a light regulator connected with the lamp socket, and a control unit for performing light regulation control on the light regulator according a control signal received by the interface unit. According to the method, when breakdown occurs in the light regulator, the lamp can be turned off in a remote way via the control unit, so that safe and reliable performance is ensured. The light-regulating power supply module can be connected in series, and has the characteristics that the forced safety standards are met and use is convenient and flexible, so that problems of a power supply network in a flexible construction area of the professional lighting power supply system for the movie, the television and the stage in the next generation can be solved.

Description

technical field [0001] The invention relates to stage and film and television lighting technology, in particular to a dimming power supply module and a control method. Background technique [0002] The traditional film and television and stage lighting power supply system (also called professional lighting power supply system) adopts the loop power supply method, and the number, location, specification and nature of each power consumption circuit have been installed and fixed in advance, which cannot be used in actual use according to the actual situation. Reasonable system adjustment of the situation, resulting in the above problems such as inconvenient use, heavy installation workload, serious waste of resources, violation of electricity safety regulations, etc., hindering the development and application of stage lighting.
