Multi-function hall speaker lighting lighting system application function request can meet the needs of a variety of comprehensive performance activities. Due to the rapid development of modern science and technology, it is necessary to fully consider the future development needs, multi-function hall speaker lighting design plan must be forward-looking and scalable, full application of modern latest technology, in order to make the system in the longest possible time with the social development of compliance.
The multifunctional hall speaker adopts multiple intelligent professional power amplifiers and multiple pairs of professional speakers, which can meet the needs of the large area of the venue in the use of more people, the sound field distribution is average, each listening point is balanced and clear. The participation of the response suppressor can effectively inhibit the sound response, and the independent conditioning of the external and internal organ makes the middle and high pitch clear and clean, the low frequency plump, and the energy strong. The application of the peripheral equipment of the power sequencer not only increases the effect, but also provides the maintenance of the system equipment, the application of professional wireless microphone, good anti-interference and strong frequency response, and high voice recovery.
Main + auxiliary sound equipment collocation, meeting sound field spread average, sound clear, plump. Noise prevention, meeting daily work meeting, video recording meeting, teaching and training meeting, etc. The whole equipment system has stable operation, comprehensive and reasonable application, simple operation and easy maintenance.
Detailed design criteria for lighting:
I. luminance index: the maximum luminance in the starring area is greater than 1200IX; A 1024 channel dimmer and a 1024 light channel. Power supply and through circuit for backup dimmer box are provided in different positions.
Two, dimming way: 384 way silicon box. To meet the needs of omnidirectional continuous lighting; Each performance position has at least four directions of light projection Angle.
Three, to provide as much as possible light position. The sense of plane with light. Avoid glare, reflection and unwanted spots.
Iv. All indexes shall not be lower than the relevant standards of the theater in the standards for the design of theater buildings in the standards for the electrical design of civil buildings established by the ministry of culture.
The selection of stage lighting equipment in the auditorium will be discussed in the following four aspects
1. Stage lighting control system
Must satisfy each kind of comprehensive artistic performance and the conference application request. To be in line with the international advanced technology, the dimming table set in the lighting control room is the control center of the entire stage lighting system. Want again appropriate Chinese national condition and the operation habit of illuminator.
2. Dimming silicon cabinet
High anti - interference, dimming silicon cabinet should think of high reliability. High stability, the request chooses the international advanced technology design the full number word dimming silicon cabinet. Less interference to audio and video; At room temperature, 220V voltage, full load, anti - interference can be strong. Within the range of 10% and 90% dimming, the filtering time of the magnetic ring is greater than 230 microseconds.
3. The lamps and lanterns
In the light of advanced performance, energy saving, long life, moderate price, lamps and lanterns configuration reasonable request. Meeting the needs of function and variety shows for the criterion. Compared with the advanced energy-saving cold beam lamps and lanterns in China, the selection of lamps and lanterns requires full consideration of opera house performance and conference function. And this luminaire can be used as both conference lighting and performance lighting. High light efficiency lens with coated optical glass lens, fitting CE standard. The beam has high quality and no distortion. With lens protection net, color frame, light hook, fit the national testing standards. Each index of domestic lamps and lanterns should be in domestic advanced. Choose high quality medium long focus spotlight, focus spotlight, ellipsoid spotlight. Other position cloth light, face light, box on the ear, side light. Use homebred spotlight, ellipsoid spotlight is replaced. Meet the stage lighting can not make the actor's clothing and stage set color distortion, meet the television video or broadcast of the light source color temperature requirements.
4. The amount of
The initiative to use the headshaking color computer lights, computer lights configuration theater can be based on the investment and then for the staging investment. With the CYM three-base color mixing system, the common patent optical design makes the optical output 50% more than ordinary computer lamp without fan cooling system, a variety of fog light, soft light effect, two-way beam spin, different beam appearance, excellent effect; Automatic overload maintenance, advanced promotion and fault finding function, lamp face plate programming, internal preset memory make this lamp use and convenient.
In a word, the first premise of multifunctional hall speaker, with modern information conference, rich functions, strong sense of experience. Meeting waiting time reduced, namely open and use, easy worry, energy saving and environmental protection.
