Abstract
The utility model relates to a mini lighting device for night use, which is used for illumination at night, comprising a one way controlled silicon SCR, an LED, a photoresistance MG, a current-limiting resistance R1 and a partial pressure current-limiting resistance R2, wherein, the current-limiting resistance R1, the LED and the one way controlled silicon SCR are connected in series; both ends of the series unit are connected with both poles of an alternating current power supply of 220V; the photoresistance MG is connected between the triggering end and the cathode output end of the one way controlled silicon SCR; the partial pressure current-limiting resistance R2 is connected between the triggering end and the anode output end of the one way controlled silicon SCR. The device is mainly used for the illumination with the mini light for families and public places at night or the decoration for commercial advertising, marks, decorations, etc.
Description
The utility model relates to a kind of lighting device, especially a kind of low-light lighting device that is exclusively used in night illumination.
The existing lumination of light emitting diode lighting device that utilizes adopts the low-voltage dc power supply power supply more, and is very inconvenient to the long-time articles for use that use of need.Adopt the 220V ac power supply, generally need add the resistance current limliting, realize circuit complexity when light-operated, the cost height with transformer step-down rectifier or diode rectification.
The purpose of this utility model is exactly the weak point that overcomes above-mentioned prior art, and a kind of simple and reliable low-light lighting device that is used for night illumination is provided.
The utility model includes unidirectional controllable silicon S CR, LED, photo resistance MG, current-limiting resistance R
1And current-limiting resistor voltage divider R
2
Unidirectional controllable silicon S CR, LED, current-limiting resistance R
1Series connection, and two ends that should the series connection group join with 220V AC power the two poles of the earth, and photo resistance MG one is terminated at the trigger end of unidirectional controllable silicon S CR, and the other end is connected to the optional position of unidirectional controllable silicon S CR cathode end, current-limiting resistor voltage divider R
2One is terminated at the trigger end of unidirectional controllable silicon S CR, the other end is connected to the optional position of unidirectional controllable silicon S CR anode output end, LED can be one or more, can be organized by the LED that a plurality of LED connection in series-parallel constitute in the same position attaching.
The utility model can be used for low-light illumination at night, or is loaded on existing decorative effect on the family daily necessity, plays the low-light illuminating effect again, or is used for playing the decorative lighting effect on sign and the billboard.
Be described further below in conjunction with accompanying drawing:
Fig. 1 is a kind of circuit diagram of the present utility model.
Fig. 2 is for being contained in LED of the present utility model and photo resistance MG in the mounting structure schematic diagram on the clock and watch card.
Among the figure: 1, dial; 2, photo resistance MG; 3, LED.
Current-limiting resistance R
1Value be to select according to the quantity and the connecting mode of selected LED, general R
1＜20K Ω.Current-limiting resistor voltage divider R
2Value select general R for use according to the model of unidirectional controllable silicon S CR and photo resistance MG
2＞1M Ω.Unidirectional controllable silicon S CR can replace with the tandem compound of bidirectional triode thyristor and unilateral diode in this device, and photo resistance MG can replace with the tandem compound of photodiode or phototriode and unilateral diode.This device circuit directly is connected on the 220V AC power, need not step-down rectifier again.The break-make of photo resistance MG control circuit, the light around photo resistance MG secretly arrives to a certain degree, and this circuit is just connected automatically, otherwise just cuts off automatically.
The utility model is compared with the light emitting diode illuminating apparatus of the existing 220V of utilization ac power supply, need not to adopt transformer, and circuit is simple and reliable, and used element is few, and cost is low, the power consumptive province, and long service life, and can realize automatic light control switch. Be used for family's low-light at night illumination, neither affect people's sleep, the low-light illumination can be provided for people's nocturnalism again. Can be used in addition public place low-light at night illumination or commercial advertisement decoration and illumination.
