Abstract
The utility model discloses an illumination control switch which can display the correct position of an illumination switch in the night. Compared with the existing product capable of displaying the position of the illumination switch, the illumination control switch is characterized in that an indicting lamp of the illumination control switch does not work when lights exist in the day and in the night and only emits lights to display the position of the illumination switch in the night. The utility model aims at providing an illumination switch with simple structure, low manufacturing cost, low power consumption, small volume and convenience for installation; and the illumination switch can be used the same as a common switch, facilitate turning on an electric lamp in dark and can be widely applied in various occasions needing illumination lamp control.
Description
Relate to the field
The utility model relates to a kind of device of bull switch, especially can be at the accurate position of display lighting at night switch breath.
Background technology
At present, existing general lighting switch can not show its switch installation site at night.It is following several that but existing display lighting switch bit is equipped with, a kind of is brushing fluorescent material on lighting switch panel, this kind mode is to utilize fluorescent material to adsorb light by day to discharge the purpose that reaches display position at night, a kind of is with direct display switch position, neon bulb crosstalk resistance back, though this dual mode method is short simple useful life; Even the switch made with electronic component is arranged individually but its method complex structure, cost height, power consumption should not be applied greatly on the general lighting switch, obviously can not well satisfy instructions for use, therefore brought inconvenience to opening electric light night.
Summary of the invention
The utility model aim to provide a kind of can be in the accurate position of display lighting at night switch, but be with the product difference of the present existing display lighting position of the switch: this product indicator light is not worked when with evening illumination being arranged by day, only in the noctilucence display lighting position of the switch.And simple in structure, cost is low, little power consumption, volume are little, easy for installation, is widely used in various lightings controls field.
Circuit of the present utility model is formed: controllable silicon VS and electric light H constitute the illumination main circuit; Control circuit is made of the voltage divider that rectifier diode VD resistance R 1R2 and photo resistance RG form.The effect of rectifier diode VD is to provide DC power supply for control loop.
The utility model is provided with the photo resistance light measurer.Described device be can be by day or night light can record its signal when opening, and for the control of light-emitting diode provides signal, described photo resistance light measurer is installed on the lighting switch panel.
The utility model is provided with light emitting display device.Described light emitting display device is being received photo resistance photometry signal and luminous under silicon controlled control, and described light emitting display device is installed on the lighting switch panel.
The utility model is such display lighting position of the switch: daytime is when the light of natural daylight is strong or when indoor illumination is bright at night, photo resistance RG is low resistance, the dividing potential drop result of it and resistance R 1, R2 makes the gate voltage of controllable silicon VS be in low level, controllable silicon VS turn-offs, and light-emitting diode H does not work; When photo resistance at night RG go up unglazed according to the time, or be radiated on the RG available light a little less than, RG presents high resistance, so make the gate voltage of VS be in high level, controllable silicon VS makes light-emitting diode H bright because of the conducting of acquisition forward trigger voltage.
The resistance of change resistance R can be adjusted starting to control of circuit a little makes electric light begin to light luminous under suitable illuminance.
Another characteristics of the present utility model are that it has soft start function.Because when night came, natural daylight is that gradual slow dies down, so the resistance of photo resistance RG increases gradually, VS gate pole level also is to raise gradually, so, the controllable silicon blocking-up becomes conducting state will experience the weak conducting phase of a lightly conducting, so bulb has a soft start-up process that brightens gradually.When the complete conducting of VS, the electric current electricity of the H that flows through also is the half-wave alternating current, and promptly light-emitting diode is to be in the under voltage operating state, and these two factors are very favourable to the life-span that prolongs light-emitting diode.The also applicable control bulb of this circuit can be removed the trouble that frequently more changes the bulb from, can economize on the use of funds again.

Fig. 2 is the embodiment installation diagram
Embodiment
As shown in Figure 1, controllable silicon VS, rectifier diode VD, resistance R 1 three element are encapsulated in the plastic cylinder pipe of Φ 10mm (as among Fig. 2 4); R2 and photo resistance RG series connection back and light-emitting diode H are loaded on the lighting switch behind respectively, and photo resistance RG and light-emitting diode H top are loaded in the hole of switch panel (as 2 among Fig. 2 and 3).
This circuit ordinary circumstance need not be debugged and can be come into operation.Ifs circuit starts to control a little improper, can suitably adjust the resistance of resistance R 2.The R2 resistance is big more, and it is low more to start to control sensitivity, and more little then sensitivity is high more.
As shown in Figure 2,1 is the general lighting switch among the figure, and 2 are photo resistance RG, and 3 is light-emitting diode H, and its bore dia is 5mm; 4 are encapsulated in the plastic insulating tube of Φ 10 * 20mm for controllable silicon VS, rectifier diode VD, resistance R 1, three element.
Selection of components and making:
Below provide the model and the parameter of device among Fig. 1:
VS adopts the less small-sized plastic packaging one-way SCR of trigger current.As 2N6565, MCR 100-8 type etc.VD 1N4007 type silicon rectifier diode.
RG can use the photo resistance of MG45 type non-tight type, requires bright resistance and resistance in the dark to differ figure place and is the bigger the better; R1, R2 1/4 fixed carbon resister; H adopts common light-emitting diode (LED).
Claims (4)
