Problems solved by technology

These straight-through power supply modules are designed for traditional professional lighting power supply systems, and 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] In addition, what is more serious is that the current air switches on these power supply modules are manual. Once the dimmer (if any) inside the module is broken down, and the power supply module may be set at any position on the stage, most of the staff will Under the circumstances, it is impossible to 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
[0006] Furthermore, most of the existing direct power supply modules are 2, 4, and 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

[0054] Such as Figure 1 to Figure 3 As shown, this embodiment provides a straight-through power supply module. The straight-through power supply module includes: a housing (not shown in the figure), a number of cables placed in the housing, a first The connector 16 and the second connector 17, the interface unit, and a set of through-socket assemblies comprising lamp sockets 61, 62, 63 connected to the plurality of cables for supplying power to the lamps.

[0055] The types of the above-mentioned first connector and second connector are male socket or female socket, and the first connector and the second connector can use the same type of socket or different types of sockets, which makes different direct power supply Modules can be connected by connecting cables. For example, if Figure 4 As shown, when the first connector and the second connector are of different types, connection cables 70 respectively provided with a male plug 71 and a female plug 72 can be used for seri...

Embodiment 2

[0070] This embodiment provides a power supply module. The difference between this embodiment and Embodiment 1 is that the interface unit of the power supply module of this embodiment receives data containing / encapsulated with DMX data packets through the network signal input interface 33, and the phase lines are connected to A dimmer 53 is provided on the cable. The control unit 40 is connected to the dimmer 53, and the control unit further includes a dimming module 42 for controlling the dimming of the dimmer 53 according to the control signal received by the interface unit.

[0071] Figure 7 Shown is a power supply module with a phase A lamp socket 61, Figure 8 Shown is a power supply module with phase B lamp receptacle 62, Figure 9 Shown is a 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.

[0072] In addition, the power supply module of this embodiment also includes a DMX ...

Embodiment 3

[0083] Such as Figure 13 , Figure 14 As shown, this embodiment provides a straight-through power supply module, the straight-through power supply module includes: a housing (not shown in the figure), a number of cables placed in the housing, a first A connector 16 and a second connector 17, an interface unit, and two or more sets of through-socket assemblies, each set of through-socket assemblies includes lamp sockets connected to several cables to supply power to lamps.

[0084] Since the straight-through power supply module in this embodiment is provided with a first connector and a second connector, two groups of straight-through power supply modules can be connected in series through connecting cables with male plugs and female plugs at both ends. The female plug of the connection cable is mated with the first connector of one of the direct power supply modules, while the male plug is mated with the second connector of the other direct power supply module to connect two...

Abstract

The invention relates to stage and film and television lighting technology, in particular to a direct power supply module and a control method. The straight-through power supply module includes a casing, several cables placed in the casing, a first connector and a second connector arranged on the casing and respectively connected to two ends of the several cables, an interface unit, and at least a straight-through socket assembly, Each group of straight-through socket assemblies includes lamp sockets connected to several cables so as to supply power to lamps, the first connector and the second connector are of a male socket or a female socket, and the first connector and the The second connector can use the same type of receptacle or a different type of receptacle. The straight-through power supply module of the present invention can be connected in series, and has the characteristics of compliance with mandatory safety regulations, convenient and flexible use, and can solve the problems encountered in the flexible formation of regional power supply networks for the next generation of film and television and stage professional lighting power supply systems.

Description

technical field [0001] The invention relates to stage and film and television lighting technology, in particular to a direct 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. [0003] The next generation of professional lighting power supply system for film and television and stage will adopt the regional power supply mode, an...
