Described optoelectronic switch 6 comprises the stationary contact 61 that is electrically connected with contact chip 3, bimetal leaf 1, quick-action spring 63, bimetal leaf 2 64, and photo resistance 65 and thermal resistance 66, described bimetal leaf 1, the stiff end of bimetal leaf 2 64 rivets together by spacing successively, described quick-action spring 63 is riveting in bimetal leaf 1, between the bimetal leaf 2 64, and be close to bimetal leaf 2 64, the three is parallel to each other, described thermal resistance 66 is located on the bimetal leaf 1 by spring clip 67, described outer ring 4, lamp ring 2, photo resistance 65, thermal resistance 66, center contact 5 is electrically connected successively, described quick-action spring 63 is provided with the movable contact 631 of an adaptive stationary contact 61, this movable contact 631 is electrically connected with center contact 5, and the spacing of described movable contact and stationary contact 61 is 0.1mm～0.3mm; Flexibly connect by metal soft wire 68 between described photo resistance 65 and the thermal resistance 66; Described quick-action spring 63 comprises movable contact spring 632, supporting spring 633, this supporting spring 633 is close to bimetal leaf 2 64, described movable contact spring 632 is fixed on the supporting spring 633 by spot welding, described movable contact spring 632 is provided with the ditch seam 6321 of two symmetries, described movable contact 631 is located at an end of movable contact spring 632, and the other end of this movable contact spring 632 constitutes free end 6322 to bimetal leaf one direction perk; The free end of described bimetal leaf 1 is provided with an adjusting that matches with movable contact spring free end 6322 and promotes screw 6323; Described movable contact 631 is 0.2mm with the spacing of stationary contact 61; Described bimetal leaf 1 is 0.1mm～0.3mm with the spacing of quick-action spring 63; Be folded with ceramic insulation sheet 68 between the stiff end of described bimetal leaf 1, bimetal leaf 2 63;
Described thermal resistance 66 adopts thick-film resistor.
In the present embodiment, housing 1 is involuted by a loam cake 11 and a lower cover 12, and a pin 661 of thermal resistance is electrically connected with the stiff end of bimetal leaf one, and this stiff end is electrically connected with center contact again, and bimetal leaf 1 is 0.5mm with the spacing of quick-action spring 63; In order to be suitable for screw lamp holder and bulb, loam cake 11 can add lamp holder, and 12 of lower covers can add lamp ring, and loam cake 11 and lower cover 12 can use shades of colour and profile, and can stick on or print additional relevant sign.
When inactive state, movable contact touches mutually with stationary contact, in order to make quick-action spring commutation circuit apace, is provided with on the free end of bimetal leaf one and regulates the promotion screw, this screw can be regulated the actuating length between bimetal leaf and quick-action spring according to the flexural property of bimetal leaf; Consider that the bimetal leaf state is different because of environment such as geographical position, season, application apparatus conditions, the bimetal leaf two of present embodiment can ambient temperature compensation, be folded with two insulating trips between the stiff end of two bimetal leafs, thermal insulation and insulating properties are better, reduced unnecessary caloric value, security and reliability promote to some extent.
The ditch of two symmetries on movable contact spring seam is divided into three with movable contact spring one, but its two ends still in succession, and the mid portion bending is extended again, make its than two length of sides some, cause the imbalance of movable contact spring tension force; This moment, when acquiring a certain degree, movable contact just left stationary contact in the free end reinforcing of movable contact spring, and bullet is to supporting spring.
In the time of bimetal leaf one heated bending, can drive thermal resistance together moves, then spurred metal soft wire and made its stretching, extension, because metal soft wire has better elastic, electric contact performance is also better, make that being connected between photo resistance and the thermal resistance is a kind of flexibly connecting, therefore its elastic pulling force can not influence thermal resistance and follows moving of first bimetal leaf, the freedom of movement of thermal resistance strengthens greatly, when mobile and bimetal leaf one remain certain coverage, guarantee good heat-conductive characteristic between the thermal resistance and first bimetal leaf, thereby guaranteed the work that whole light-controller can be stable.
Photo resistance in the present embodiment, thermal resistance is connected with lamp holder outer ring and center contact all the time, optoelectronic switch also is in and the lamp holder center in original state, the state that contact chip is connected, when illuminance becomes big, the resistance of photo resistance diminishes, the electric current of thermal resistance of flowing through becomes big, the thermal resistance heating, after being heated, the bimetal leaf of to a certain degree being close to thermal resistance produces deformation when generating heat, the adjusting that is arranged on bimetal leaf this moment promotes the movable contact spring (free end) that screw just promotes the quick-action spring, and movable contact and stationary contact on the movable contact spring are broken away from, and switch in opened condition, circuit does not form path, lamp is closed, and when illuminance diminishes, it is big that the resistance of photo resistance becomes, the electric current of thermal resistance of flowing through diminishes, thermal resistance does not generate heat gradually, and this moment, bimetal leaf returned to the original form, and the movable contact spring in the quick-action spring also returns to original state after breaking away from thrust, this moment in the movable contact spring movable contact and the stationary contact closure in the lower cover, switch also is closure state, makes circuit form path, and lamp is lighted.Maximum delay according to the advance copy light-controller is 120 seconds, has the function that anti-high light disturbs.
