Abstract

The utility model relates to a photoelectric controller, in particular to a photoelectric controller for lighting lamps in a corridor. The photoelectric controller comprises a power circuit, a detecting circuit and a control circuit; a photosensitive resistor RG of the detecting circuit is connected to the inverted input terminal of a comparer A; the output terminal of the comparer A is connected with the base electrode of a crystal triode T of the control circuit; and the output terminal of a relay J, which is connected with the collecting electrode of the crystal triode T, is connected with a load lamp. The photoelectric controller is used for controlling the continuous night lighting of the light lamps in the corridor, and people frequently lighten the lamps without making sounds, so that the rest of residents and the physical and psychological health of the aged cannot be affected. Therefore, the good lighting effect of the corridor can be achieved, the waste of electric energy can be reduced, and the energy saving effect is remarkable.

Description

Photoelectric controller

Technical field

The utility model relates to a kind of electronic controller, specifically a kind of photoelectric controller of corridor lighting.

Background technology

In daily life, people in the dark corridor of night or light, often see and what use is the acoustic control lamp of installing in the corridor.This acoustic control lamp is to be made of acoustic control lamp holder and incandescent lamp, and when light dark (darkness), people enter corridor needs illumination, and this lamp is the sound such as clapping hands or stamp one's foot that sends by the people, lights acoustic control lamp.Normally in the building every layer this acoustic control lamp all is installed because this lamp need be sounded and just can be lighted, after night, people had a rest, the sound that sends can influence resident's normal rest, and can bring the body and mind injury to resident old or that have a heart disease.And can be because the frequent starting of acoustic control lamp holder easily causes the high and lighting damage of failure rate.This acoustic control mode, even when lamp is not lighted, because self power consumption of acoustic control lamp also causes certain waste of energy,

The utility model content

The purpose of this utility model provides a kind of sound that need not to send, and just can realize the lighting device of brightening effect in the corridor.

The utility model is to utilize natural daylight in the corridor, design according to the photo-electric control principle, it comprises power circuit, testing circuit and control circuit, the photo resistance RG of testing circuit is connected to the inverting input of comparator A, the transistor T base stage of the output connection control circuit of comparator A, the collector connection relay J coil of transistor T, control relay coil break-make, relay J output termination load lamp tool.

Do not interrupt illumination the night that the utility model can be used for controlling the illuminating lamp in the corridor, do not need people to send the sound and frequently light light fixture, can not influence resident's rest and the elderly's physical and mental health.Can realize brightening effect preferably in the corridor, and can reduce waste of electric energy, energy-saving effect is remarkable.

Fig. 2 is a scheme of installation of the present utility model.

Embodiment

Mounting means of the present utility model as shown in Figure 2, the R termination 220V power supply of photoelectric controller G, C end links to each other with commercially available energy-efficient lamp.

Its operation principle as shown in Figure 1, the transformer B output AC voltage of power circuit provides DC power supply through bridge rectifier Q, is the power supply of testing circuit and control circuit.Resistance W1, the R1 of testing circuit, R2, W3 provide the reference voltage of a homophase input for comparator A, and resistance R 3, W2 are used for cooperating photo resistance RG to adjust the critical illuminance value of illuminating lamp.When illuminance is big (greater than 20Lx), photo resistance RG resistance reduces, and photoelectric current increases, and comparator A is output as low level, and triode T is in cut-off state, not adhesive of relay J, and the corridor lamp outage is extinguished.When illuminance decline, when being lower than comparator A in-phase input end preset threshold voltage, comparator A output switching activity is a high level, after the triode T conducting, and the relay J adhesive, power connection, corridor lamp is lighted.Regulate W2, can adjust the B.C.D. value of lighting corridor lamp.For the generation repeatedly that prevents that relay J is beated when the B.C.D., can be by adjusting the hysteresis amount that the W3 that is connected in series with R5 regulate comparator A.

Claims

1. photoelectric controller, the DC power supply that provides by power circuit, it is characterized in that: the testing circuit photo resistance RG that gets illuminance is connected to the inverting input of comparator A, the transistor T base stage of the output connection control circuit of comparator A, the collector connection relay J coil of transistor T, relay J output termination load lamp tool.

2. according to the described photoelectric controller of claim 1, it is characterized in that: resistance W1, the R1 of testing circuit, R2, W3 provide the reference voltage of a homophase input for comparator A, and resistance R 3, W2 are used for cooperating photo resistance RG to adjust the critical illuminance value of illuminating lamp.
