Principle and application of light control switch
Introduction to Optical switches
Optical control switch adopts advanced embedded microcomputer control technology, which is a multi-functional advanced time controller (time control switch) integrating optical control function and common time controller. According to the need of energy saving, you can enable the light control probe (function) and time control function at the same time to achieve the best energy saving effect. Light switch can be widely used in streets, railways, stations, waterways, schools, power supply departments and other places that need time control.
Application of optical switching principle
This series of intelligent light switch can control the power switch freely according to the time (illumination threshold) set by the user. Widely used in street lamps, neon lights, advertising lights and other electrical equipment that need to control the power switch according to the time. You can set four groups of switchover time as required to implement multi-period switchover. Users can also use the light control probe to collect local illuminance, according to the illumination to achieve the switch of lights.
Connection of optical switches
Light-controlled switches are widely used to improve work efficiency by controlling lighting. However, there is a contradiction between the current-carrying capacity of the contacts of the light-controlled switch and the high-power lighting current, because the current-carrying capacity of the contacts of the light-controlled switch is not large. In order to solve this problem, we often use the light control switch to control the contactor, and then use the contactor to control the lamp. When wiring, note that the light switch and contactor button must be in the same phase, and disconnect the contactor "self-protection wire". If you do not pay attention, it is likely to cause the control circuit short circuit or the contactor can not be released after pulling in.
The light-controlled lighting distribution box can not only be assembled by itself, but also save money. In addition, the light control lighting distribution box with indicator light can also help electricians to quickly determine the failure of lighting circuit components, effectively shorten the time to determine the failure, accelerate the maintenance speed. The contactor of the optical control lighting distribution box adopts the contactor whose coil voltage is 220 VOLTS, which is consistent with the operating voltage of the optical control switch. The led indicator light of the same operating voltage is also used as an indicator light. In order to facilitate wiring, lamps, light switches and other external devices are connected through terminals; Different grades of terminal boards are required to prevent incorrect wiring of the lamps and light switches.
Light switch lighting usually has two common failures: the floodlight is not on or the floodlight is always on. These two faults may occur in the light control state or in the manual control state. Under manual control, there are usually four kinds of failure, respectively: light control when the lamp is not bright, manual control when the lamp has been bright, manual control when the lamp has been bright.
Light control switch is widely used in street lamps, landscape lights, advertising light boxes, neon lights and other equipment, greatly saving people's workload, efficient and timely. The light control switch can time the system itself and set the light intensity itself. When purchasing optical switches, first read the instructions carefully to ensure that the connection of the optical switches is correct. When using the optical switch, pay attention to the use method to avoid premature damage to the switch.
