Abstract
The utility model relates to a light-sensitive automatic control lamp holder comprising a lamp holder body and a light-sensitive resistance in the lamp holder body, wherein a light source interface lamp holder is arranged on the lower end of the lamp holder body, an automatic control mechanism controlling the make-and-break between an external power source and a light source interface lamp holder is arranged in the lamp holder body, the automatic control mechanism is connected with the light-sensitive resistance, the automatic mechanism comprises a bimetallic plate, a fixed contact blade and a movable contact blade, wherein contacts on the fixed contact blade and the movable contact are opposite, the bimetallic plate is matched with the movable contact blade, a limit resistance is connected between the bimetallic plate and the light-sensitive resistance in series, the limit resistance clings to the bimetallic plate, the movable contact blade is an elastic rocking structure, the middle portion of the movable contact blade is fixed on a support, and the support also adopts the bimetallic plate. The lamp holder can overcome the defect that a common electronic lamp holder is not suitable for a fluorescent lamp in the prior art, through the design, the lamp holder is suitable for a filament lamp and the fluorescent lamp, and has the advantages of simple structure, high sensitivity, long service life and strong reliability.
Description
Affiliated technical field
The utility model relates to a kind of photosensitive automatic control lamp holder.
Background technology
Traditional electronic type lamp holder, and be not suitable for fluorescent lamp and use, its reason is that the electronic type lamp holder controls by controllable silicon, and the circuit in fluorescent lamp such as the electricity-saving lamp is an oscillating circuit, both also do not match, as being used in combination by force, the ghyristor circuit phase place can be destroyed the oscillating circuit in the electricity-saving lamp, electricity-saving lamp is constantly glimmered even burns out.
Summary of the invention
Common electrical minor lamp holder is not suitable for the problem that fluorescent lamp uses in the prior art in order to overcome, and the utility model provides a kind of photosensitive automatic control lamp holder, simple in structure, the good reliability, highly sensitive of this photosensitive automatic control lamp holder; Be not only applicable to incandescent lamp, and be applicable to fluorescent lamp.
The technical scheme that its technical problem that solves the utility model adopts is: comprise the photo resistance in body and the body, the lower end of body is provided with the light source interface lamp socket, be provided with the automatic control mechanism of break-make between control external power supply and the light source interface lamp socket in the body, automatic control mechanism links to each other with photo resistance.
Automatic control mechanism is made of bimetal leaf, static contact and movable contact spring, and static contact is relative with contact on the movable contact spring, and bimetal leaf matches with movable contact spring.
Series limiting resistor between bimetal leaf and photo resistance, current-limiting resistance is close to bimetal leaf.
Movable contact spring is the elastics wing structure, and its middle part is fixed on the support, and support is with adopting bimetal leaf.
Be connected and fixed by screw and insulating part between the bimetal leaf of static contact and both sides, the support.
The utility model is by above-mentioned specific design, not only is suitable for incandescent lamp and uses, and be applicable to fluorescent lamp, has the advantage of simple in structure, highly sensitive, long service life, good reliability.
Description of drawings
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Accompanying drawing is a structural representation of the present utility model.
Embodiment
As shown in the figure, the utility model comprises the photo resistance 2 in body 1 and the body 1, the lower end of body 1 is provided with light source interface lamp socket 3, is provided with the automatic control mechanism of break-make between control external power supply and the light source interface lamp socket 3 in the body 1, and automatic control mechanism links to each other with photo resistance 2.Automatic control mechanism is made of bimetal leaf 4, static contact 5 and movable contact spring 6, and static contact 5 is relative with contact on the movable contact spring 6, and bimetal leaf 4 matches with movable contact spring 6.Series limiting resistor 7 between bimetal leaf 4 and photo resistance 2, current-limiting resistance 7 is close to bimetal leaf 4, and current-limiting resistance 7 generates heat under user mode, can improve the reliability that bimetal leaf 4 temperature distortions trigger movable contact spring 6 actions.Movable contact spring 6 is the elastics wing structure, and its middle part is fixed on the support 8, and its fixed form can adopt spot-welded structures, and the support 8 same bimetal leafs that adopt have the ability that temperature distortion makes movable contact spring 6 actions too.Be connected and fixed by screw 9 and insulating part 10 between the bimetal leaf 4 of static contact 5 and both sides, the support 8.In working order down, when illumination was big in daybreak, the resistance of photo resistance 2 reduced, electric current passes through, and current-limiting resistance 7, bimetal leaf 4 and support 8 all generate heat, and bimetal leaf 4 and support 8 flexural deformations make movable contact spring 6 actions, movable contact spring 6 separates with contact on the static contact 5, and circuit disconnects; Otherwise when It is getting dark when illumination diminishes, the resistance of photo resistance 2 increases, limited passing through of electric current, current-limiting resistance 7, bimetal leaf 4 and support 8 generate heat hardly, and bimetal leaf 4 and support 8 reset and make movable contact spring 6 actions, contact on movable contact spring 6 and the static contact 5 is fitted, circuit turn-on.
