Abstract
The utility model relates to a full automatic optical control switch, which belongs to the technical field of electric switches. The full automatic optical control switch is mainly used on various occasions in the public illuminating devices, such as lighthouses, navigation marks, long distance electricity utilization control, etc. The switch is characterized in that the switch is composed of a cover body, photoresistors, an insulating cover, a heating element, a thermal relay and a base. The heating element and the thermal relay can be replaced respectively by a thyristor and an ordinary relay or a bimetallic strip, which enables the switch to become another two kinds of full automatic switches. The utility model fully utilizes the brightness of natural light to automatically switch on and off, without the limitation of season and region, and has the advantages of sufficient utilization of power, power saving, simple structure, low cost, long service life, high safety, wide purpose, etc.
Description
A kind of light-operated full-automatic switch belongs to the appliance switch technical field.Be mainly used in public illumination equipment, beacon, navigation mark, far away under the various occasions on the way with energising and outages automatically such as electric control.
Switch commonly used in prior art is broadly divided into manual control switch and this two big class of mechanically controlled switch.The former is as hand-pulling switch, key switch, pulling switch and various knife switches etc.; The latter such as relay switch, air delay switch etc. are not seen full-automatic switch as yet.Above-mentioned existing switch, no matter which kind of, all need hand control or setting, often because artificial carelessness or be subjected to restriction or other accidental causes of objective condition, can not in time cut off the electricity supply and the daytime occur and still display a light, cause the significant wastage of electric energy and power consumption equipment, very cause and human casualty accident to occur.Undergo mutation when being badly in need of wanting light when weather on the other hand, but can not in time switch on, thereby cause shut-down, suspend classes, phenomenon such as traffic order confusion, particularly can not in time switch on, can cause the serious consequence that can't remedy owing to the light on the operating table.For electrical energy saving with guarantee Electrical Safety and can must solve the full-automatic switch problem according to people's desirable switching lamp in time.
The purpose of this utility model be to provide a kind of simple in structure, small volume and less weight, esy to use, safe and reliable, do not need Artificial Control and manipulation, also not normal maintenance, fully by the i.e. switch voluntarily of the shading value of available light, electrical energy saving is not limited by season and region again, broad-spectrum light-operated full-automatic switch.
According to the basic principle of illumination purposes and appliance switch and the characteristic of photo resistance, at the subject matter that exists in the prior art, basic design of the present utility model is: utilizing one of photo resistance control is the thermal relay of its heating by heating element, changes according to the available light light and shade fully and opens automatically or powered-down.
Of the present utility modelly be characterised in that described light-operated full-automatic switch, constitute by a cover body, a photo resistance, an insulating lid, one group of heating element, a thermal relay and a base; Above-mentioned photo resistance, heating element and thermal relay are installed on the above-mentioned base and (are that above-mentioned photo resistance, heating element and thermal relay connected successively by the circuit shown in the accompanying drawing 2, the other end of photo resistance is connected with one power line of straight-through load, another strand of termination power line that heating element and thermal relay are in series, another another strand of termination load line of thermal relay), with lead said elements is coupled together.Feature of the present utility model is that also above-mentioned heating element replaces with controllable silicon, and thermal relay replaces with common relay and install a diode additional between above-mentioned photo resistance and controllable silicon, is the light-operated full-automatic switch of electronic type.Above-mentioned again thermal relay replaces with bimetal leaf, is the light-operated full-automatic switch of bimetallic contact type.
The utility model has the advantages that: utilize the available light shading value to open or close power supply in the lighting apparatus automatically fully, neither be subjected to the influence of seasonal variations, be not subjected to the restriction of region yet, can turn off the light to arbitrary the turning on light of the needs of illuminating ray according to people fully, electricity its usefulness to the greatest extent can be made, electric energy can be fully saved again; This construction of switch is simple, cost is low, volume is little, attractive in appearance, easy to install, the life-span is long, key element can reach more than 100,000 hours, need not keep in repair, safe and reliable, applied range, public place illuminating lamps such as all kinds of exhibition show windows in lavatory, family corridor, shop, propaganda board, notice board, various decorative lamp, station, harbour, each industrial and mining enterprises produces upward used work light, street lamp, beacon, navigation mark and way far away and all can use with electric control or the like.
Accompanying drawing 1 is one of the utility model most preferred embodiment assembling back overall structure vertical profile schematic diagram, and Fig. 2 is each components and parts connection line figure, 1 cover body among the figure, 2 photo resistance, 3 insulating lids, 4 heating elements, 5 thermal relays, 6 bases.
Change as present embodiment:
1, replaces heating element with controllable silicon, replace thermal relay and between photo resistance and controllable silicon, install a diode additional, be the light-operated full-automatic switch of electronic type with common relay;
2, replace thermal relay with bimetal leaf, be the light-operated full-automatic switch of bimetallic contact type.
Claims (4)
1, a kind of light-operated full-automatic switch of the present utility modelly is characterised in that described light-operated full-automatic switch is made of cover body 1, photo resistance 2, insulating lid 3, heating element 4, thermal relay 5 and base 6; Above-mentioned photo resistance 2, heating element 4 and thermal relay 5 are installed on the base 6 and by certain circuit and are interconnected by lead, and above-mentioned insulating lid 3 covers on heating element 4, cover body 1 be buckled in above-mentioned all above the element.
2, light-operated full-automatic switch according to claim 1, it is characterized in that above-mentioned certain circuit is: photo resistance 2, heating element 4 and thermal relay 5 are connected successively, the other end of photo resistance 2 is connected with one power line of straight-through load, another strand of termination power line that heating element 4 and thermal relay 5 are in series, another another strand of termination load line of thermal relay 5.
