In KTV we all know that different lights give people different feelings, so how to control the lights and how to debug the lights to customers is the current major issue:
KTV lighting control is mainly reflected in two aspects: the brightness of the lighting and the color of the lighting stage lighting.
We control the brightness of the general species: a method called mechanical addition and subtraction, that is, by controlling the number of lighting lamps, to achieve the total intensity of light to increase or decrease control. For a single lamp, a light plate or an iris can be used to change the amount of light transmitted by the lamp. Another method is the electrical control method, which uses different dimmer devices to change the operating voltage of the lamp to adjust the light emission of the lamp. Brightness, both methods have their own advantages and disadvantages, the advantage of the first method is that it does not affect the color temperature, but the adjustment is not convenient. The second method is simple, and can achieve automatic and program-controlled operation, the disadvantage is that while changing the luminous intensity, color temperature and color rendering has a greater change, not easy to control, so choose carefully!
If the principle of electrical control of light, it can be divided into two kinds of luminous intensity control and on-off control, corresponding to the switch control and dimming control two methods.
First, use the switch control
The general lighting switch control device refers to the control of the lighting circuit on and off, that is, various switchgears that control lighting and extinguishing of the lamps, including knife switches, contactors, and air switches. Among them, the air switch is widely used as the on-off control and lighting master switch of high-power lamps in dance halls due to its good protection function.
The use of toggle switches or air switches to control light on and off is the most common manual switch control device. For example, the L1151012-type 12-circuit switchboard is composed of twelve groups of fifteen-A ship-shaped switches and fuses, which can control twelve lights respectively. It is suitable for lamps with a current less than 15A, such as various types of laser lights, rotating lights, violet lights, glass balls, strobes, and most lens-action lamps. For high-power spotlights, floodlights, and follow-up lights, DZ-type air switches or CJ10 contactors with strong arc extinguishing capability are suitable.
Since KTV needs to exhibit rich and varied lighting art effects, in addition to using manually operated switchgear, sound control, program control, and even computer-controlled switch control devices with various special functions are used.
The voice-activated lighting device can make the light flash, swing or rotate with the beat of the music. There are two ways to control the sound of a light: First, there is a voice control function on the luminaire. The luminaire is equipped with a microphone, amplifier, relay, or thyristor (thyristor). It directly senses the sound of the outside world and controls the action of the motor, causing the luminaire to scan or swing. Rotate and other actions. The other is that the light console itself has a voice control function. The principle is to send the sound signal of the mixer to the sound control circuit of the light console (light control station) to control the on and off of each group of lights. This method is particularly suitable for controlling the lighting action of a large number of groups, causing them to ignite in turn as music beats to create a flickering effect.
Program-controlled lighting control equipment is the use of touch-button, through the digital control circuit to trigger the SCR on and off, in order to control the grouping of the various lamps in accordance with a certain program in turn ignited and extinguished, resulting in a certain artistic effect. It is particularly suitable for lighting fixtures that require continuous rounds of circulation in order to achieve a change of color, pattern, and effect in the frontier, such as rain lamps, spotlights, and boundary lights.
