Abstract
The utility model discloses an optically controlled table lamp, which relates to an illuminative lamp with automatic light regulation, the utility model relates to a table lamp with a photosensor, comprising plug, a switch, a bulb and a spot light cover, powered with 220V AC. A photosensor with a photoresistor is arranged on the table lamp to regulate internal current with change of brightness on the table to regulate the brightness at a proper level; in case of the environmental brightness exceeding over certain limit, the table lamp may shut up automatically. In case of the environmental brightness being lower than a limit, the table lamp will switch on automatically. The utility model is mainly used for illumination with automatic regulation for protection of eyesight.
Description
Technical field
The utility model relates to a kind of novel illumination utensil, particularly relates to a kind of Light operated desk lamp of automatic adjusting illumination brightness.
Background technology
The student is vision protection when study, should adjust lamp brightness according to ambient conditions, but the brightness of existing common desk lamp can not be regulated brightness automatically according to the variation of ambient brightness.
Summary of the invention
In order to solve the problem of above-mentioned existence, a kind of Light operated desk lamp that the utility model provides according to the variation of ambient brightness, is regulated the brightness of desk lamp automatically by a light sensor, keeps academic environment to be under the optimum brightness, with vision protection.
The technical solution of the utility model is that this Light operated desk lamp comprises a desk lamp and a light sensor composition.Described desk lamp is made of attaching plug, switch, bulb and lampshade and light sensor, uses 220 volts alternating current.A light sensor is set on described Desk lamp feet, in photo resistance is arranged, photo resistance is serially connected with in the circuit that switch, bulb and power supply form.It can regulate the variation of internal current with the variation of brightness on the desktop photo resistance, thereby adjusts the variation of desk lamp brightness, makes desktop remain suitable brightness, neither can be bright excessively, can be not dark excessively yet, thus vision protection.And when the ambient brightness around the desk lamp surpassed certain limit, desk lamp can be closed automatically; When ambient brightness is lower than a certain limit, can open automatically.The switch of desk lamp can be controlled entire circuit.
The beneficial effects of the utility model are to use simply, automatic brightness adjustment, vision protection.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the electrical schematic diagram of the utility model embodiment;
Fig. 2 is the structural representation of the utility model embodiment.
Among the figure, 1. bulb, 2. attaching plug, 3. light sensor, 4. switch.
The specific embodiment
As shown in Figure 2, Light operated desk lamp is made up of a desk lamp and a light sensor.Described desk lamp is made of attaching plug 2, switch 4, bulb 1 and light sensor 3, uses 220 volts of alternating currents.In the light sensor 3 photo resistance is arranged, photo resistance is serially connected with in the circuit of switch 4, bulb 1 and power supply composition as Fig. 1.It can regulate the variation of internal current with the variation of brightness on the desktop photo resistance, thereby adjusts the variation of desk lamp brightness, makes desktop remain suitable brightness, neither can be bright excessively, can be not dark excessively yet, thus vision protection.And when the ambient brightness around the desk lamp surpassed certain limit, desk lamp can be closed automatically; When ambient brightness is lower than a certain limit, can open automatically.The switch 4 of desk lamp can be controlled entire circuit.
The utility model cost is low, simple in structure, be suitable for popularizing.
