Abstract

The utility model relates to an automatic switching electricity-saving lamp. A relay seat is arranged between a lamp bulb and a lamp holder. A relay tenon is extended out of one side of the relay seat. A photoresistor and relevant circuits are arranged. The switch of the on and off of the lamp bulb can be automatically realized by the luminosity change of the photoresistor of the relay seat along with the environment. Thus the power saving effect is further obtained.

Description

Automatic switching electricity-saving lamps and lanterns

The utility model relates to the control to light fixture, particularly relates to a kind of power saving light fixture that can do automatic switchover with the bright and dark light variation.

The particularly invention of electric light of throwing light on is prolonged the activity of human beings time.Yet, because forgetting easily with daybreak, people turn off the light (the particularly street lamp on garden or doorway and decorative lamp etc.), can form the unnecessary waste of electric power.

Usually people are self-consciou or turn off the light with promptings such as indicator light, photo-electric control signals, perhaps establish the special messenger to manage, and cause the waste of the unreliable or manpower of effect.

The purpose of this utility model is to provide at above problem a kind of power saving light fixture of simple and effective automatic switchover, it can with night on daytime light light and shade change and close and open light fixture automatically, to reach energy savings.

The purpose of this utility model is achieved in that between traditional lamp socket and bulb, and a relay seat is set, and the one side is extended a relaying tenon that a photo resistance is arranged and be connected with power circuit in it.Because photo resistance can make it impedance and reduces or increase with the luminosity of light is strong and weak, so the may command bulb is not luminous or luminous.This photo resistance can be with silicon controlled rectifier and commutator circuit cooperating and light fixture is automaticallyed switch.

The utility model is because only need install the relay seat that constitutes with a few components additional between prior lamp holder and bulb, easy to use so it is simple and reliable, with low cost.

Concrete structure of the present utility model and circuit are provided by following examples and accompanying drawing.

Fig. 1 is the three-dimensional part exploded view of the utility model light fixture;

Fig. 2 is the combination schematic perspective view of the utility model light fixture;

Fig. 3 is the circuit diagram of the utility model light fixture.

As shown in Figure 1, the utility model light fixture is combined by traditional lamp socket 1, one relay seat 2, one bulbs 3 basically.

Wherein, lamp socket 1 is a known device, and former purpose is for bulb 3 solid locks, but in the utility model, for the usefulness of interlocking relay seat 2, so its upper end inwall is provided with a line 11, remainder is the same with existing lamp socket, so do not give unnecessary details at this.

Relay seat 2 is a tube, and its lower end is provided with relaying ring grain 21, and can be sealed with it corresponding to aforementioned seat line 11, and the inwall of upper end also is provided with relaying end grain 22, so that it can be sealed with bulb 3.And the one side is then extended a relaying tenon 23, sets a photo resistance (CDS) 24 in it, and makes outside its inductor is exposed to, and circuit as shown in Figure 3 is set therebetween.

Bulb 3 also is a known device, and its lower end is a lamp holder 31, and its size is corresponding to aforementioned relaying end grain 22, makes it can be sealed mutually.

Please consult all figure again.When implementing the utility model, after its assembling promptly as shown in Figure 2.When switch switches to when connecting, then since photo resistance 24 have with the strong and weak characteristic that changes resistance of the luminosity of light, so in the daytime or when sunny, its impedance is very low, makes bulb 3 not luminous, but when night or light are lower than default luminosity, then impedance this moment becomes big, and bulb 3 is promptly luminous.If not the time spent, then relay seat 2 need only be removed, again bulb 3 is locked on the lamp socket 1, be the general lighting utensil.

Please consult the circuit diagram of the present utility model of Fig. 3 again.Under normal brightness, the voltage that A is ordered (by the internal driving dividing potential drop of resistance R 1 and CDS) deficiency is so that Zener diode ZD punctures, and silicon controlled rectifier SCR does not work; And during the brightness deepening, the CDS impedance increases, and the A point voltage improves, when reaching the ZD breakdown point, trigger SCR simultaneously, and make the SCR conducting, make circuit be channel status, at this moment, bulb by photo resistance 24 controls is promptly luminous, so, as long as change resistance value or the ZD of R1, can adjust suitable bulb brightness.

For overcoming the bulb brightness deficiency, the utility model light fixture can add after the power supply input to be put commutator and is full-wave rectification.

Therefore, when implementing this case, it can be in automatic bright lamp and cut off daytime voluntarily at night, and the wasting phenomenon of turning off the light is forgotten in the daybreak of avoiding turning on light frequent evening.
