As a local television station, relative to the central and provincial TV stations, the frequency of use of studio is very low, with the stage lighting equipment and operator is pitiful. The use of good, good use of the existing equipment, with less people and produce high quality and good effect of art shows, is our common responsibility of local television station, studio recording personnel. Stage lighting equipment referred to in here refers to the computer lights, smoke machine, snow machine, bubble machine, colorful gun etc..
Using a computer and console lights. The city television station Limited financial resources, funding constraints, in the purchase of computer lights and console equipment is often purchased in batches repeatedly, often causing computer lamp configuration quantity are few, but the hybrid models, product performance is uneven, caused some trouble and difficulties to use. Especially the control part is often a special type computer lamp matching and to console the first purchase, the computer light control of other types of type is not very effective. In the long-term use of the process, we explore a set of how to adjust the special simple console method to realize the control of different types of computer lamp.
There are three reasons:
(1) there is only one DMX512 signal output to the console port, not divided into a plurality of control line to control different lamps;
(2) computer lamp of the console originally only control type, address code setting as long as the lamp set can be added the number of channels, the number of channels such as different lamps with the original lamp case, there will be covered or the original light channel cover may;
(3) special console built-in lamp base does not support the new lamp, cannot correctly display control channel number and the name of the new lamp, is not conducive to the maintenance and use. Our original 4 scanning computer lamp, then bought 8 sets of domestic head light. Due to financial reasons, we can not buy new general-purpose computer console lights, in order to solve this problem, we have adopted the following methods: No. 4 by the original US computer lamp (both the last scan light) leads to a signal line to the new lamp lights out 1, 12 computer lights all series together, controlled by a signal line, solve the problem of DMX512 signal output; then we took a two lamp channels as the standard to set the address code, the original lamp is a 16 channel, new light is 8 channel, we will address code between interval is set to 16. This will ensure that each lamp are controlled without channel covered problem; finally, we prepare the new lamp base in accordance with the new lamp each channel function, enable the console can identify new fixtures. So that we can correctly use lamps, various programming. Of course, this is only in conditions of limited circumstances after all a matter of expediency, relatively cumbersome in use, conditional word or the choice of general-purpose computer console lights for the benefit. Two control computer lamp power use.
As we all know, the computer lamp life is 750 hours, not hot trigger (start), after burning to be the light bulb cooling can restart. According to the characteristics of it, we in the arts program rehearsal video, as far as possible will need to use computer lamp to heighten the atmosphere of song and dance show centralized recording, to shorten their time of use. In order to avoid sudden blackouts, quickly call or instant power failure brought to the computer lights since the start of the (hot start) impact damage, we have taken measures, below the air switch supply computer lamp power supply, installation of AC contactor. The control of AC contactor closed push button switch, leading to the lighting control room. This is to avoid self starting power outage calls after the computer lights, and reduce personnel back and forth shut off the power of toil.
Three. Use smoke machine and bubble machine
We XX TV two Taiwan hood, was purchased in 1996, the line of control each hood is only 5 meters long. When using, need two people control on the stage. It is difficult to communicate and director, and the two hood smoke rate is not consistent. In view of this situation, we made the following improvements, lengthened the line of control, measure is: two for five core cable 30 meters, welding on the five core head (control line hood is a five core). Along both sides of the stage wall led to the device layer, one side again by the equipment layer lead to light up, find another two is about 6 meters long work core cable. In the female head welding five core head, first find out the smoke point control line (control line hood consists of five core, respectively is 1 ground 2 point control of 3 timer 4 normally open 5 of public power and public power line), together with the welding welding. Two of 2 core cable. After welding and the original controller for inserting, welding the two 2 core. On the other end is connected to a double control switch cable. It must be noted that, from two in 2 core cable two smoke control line and out, can only be received in a double control switch four contacts, so as to avoid phase sequence power of two hood connecting different, cause a short-circuit fault. Double control will control the hood switch is fixed on the handle light bulbs, the two original controller hood fixing lamp frame in light up on the. So, in the operation of light up at the same time, can also manipulate the hood. When need two hood also smoke, double control switch on the handle point you light up. When in need of a range hood smoke, on the point of the controller that Taiwan hood, very convenient. |
