Abstract

The utility model discloses an antifog mirror with an LED (light-emitting diode) lamp, which comprises a mirror, an electric heating plate adhered to the back of the mirror, a frame, an LED luminaire mounted at the top of the frame and a heating control circuit, wherein an illumination angle of the LED luminaire is rotatable; a temperature sensor and a humidity sensor mounted on the mirror are electrically connected with a heating controller to automatically control on and off of alternating current of the electric heating plate; and LEDs and the heating controller are powered by a power adapter. When the lamp is turned on to use the mirror, the illuminating angle is adjustable; once the humidity sensor identifies fogging of the mirror, the circuit automatically switch on the heating plate to work to remove condensed fog; the temperature sensor is used for acquiring heating data to prevent overheating; and the luminaire has a non-fogging function due to a heat-dissipation design of the LED lamp. The antifog mirror combines the mirror and the lamp into a whole, and is convenient to mount and use, energy-saving, and environment-friendly, and the service life of the whole antifog mirror can be prolonged.

Description

A kind of Anti-fog mirror with the LED lamp

Technical field

The utility model relates to a kind of anti-fogging mirror that uses in the places such as bathroom, Dressing Room, especially with the Anti-fog mirror of lamp.

Background technology

Because common mirror is running into when being chilled to heating temperature and changing, particularly the mirror in the bathroom is after shower, and mirror surfaces affects people's normal use because of the relatively cold water steaming mist vapour phenomenon of condensing that produces.Therefore on market and the invention technical elements some Anti-fog mirrors have appearred, as the patent No.: 201020033047.5.And a lot of Anti-fog mirrors are not with essential lamp lighting function, need another the purchase to install in use, trouble is installed like this and will connects two power lines, the poor while of overall appearance sense has also increased cost, and general light fixture does not all have anti-fog function to be easy to condensing water droplet.Existing a kind of band lamp Anti-fog mirror on market and for example, adopt the mercury lamp pipe to be entangled in the edge at the mirror glass back side, adding a heater forms again, due to lamp directly to the mirror front irradiation, very dazzling when looking in the mirror, not to be that energy-saving environmental protection lamp and mirror are very thick take up space greatly the mercury lamp pipe, and heater does not have automatic control function simultaneously, exist power consumption large, use inconvenience and easily caused the shortcoming of cause thermal damage mirror.

Summary of the invention

In order to solve existing Anti-fog mirror or not to be with lamp, the automatic control function that do not have with lamp, exist power consumption large, use inconvenience, use up the problems such as unreasonable, it is a kind of with the LED lamp that the utility model will provide, use up rationally, the compact conformation save space, and have intelligent control function, the anti-fogging mirror of energy-conserving and environment-protective, while LED lamp wherein also has anti-fog function.

The technical solution adopted in the utility model is: an electric boiling plate is pasted at the back side at a mirror, and embedding is installed on the base plate of framework, a temperature sensor and a humidity sensor are installed on mirror, and frame roof is installed the LED light fixture that there is rotating shaft at a strip two; Temperature sensor and humidity sensor are electrically connected to respectively two transducing signal inputs of a heating controller, the control output end of heating controller connects an on-off circuit that is used for controlling electric boiling plate, electric boiling plate connects the alternating current line ball by on-off circuit, LED is connected a power supply adaptor with heating controller generating positive and negative voltage end, power supply adaptor incoming transport pressure-wire, alternating current line ball input connects a power switch.Above-mentioned LED light fixture is welded on the strip aluminum-based circuit board by a plurality of paster LEDs, paste with strip aluminium heat sink strip and be contained in together in shell and light-passing board, and shell and light-passing board are close in strip aluminium heat sink strip edge, and purpose is to allow the heat that LED gives out be transmitted to the mist vapour effect of playing dispersing surface on shell and light-passing board.when using mirror when turning on light, can rotate on demand the LED lamp and form suitable lighting angle, in case there is a small amount of mist vapour to be condensed on mirror, humidity sensor triggers heating controller opening switch circuit, allow electric boiling plate pass into alternating current work heating, mist steam raising on mirror is gone out, after sensing dry signal, touches by humidity sensor heating controller closing switch circuit, allow electric boiling plate outage stopped heating, waste heat makes the mirror surfaces mist vapour that temporarily can not condense again, this process is carried out automatically repeatedly, temperature sensor is used for to controller sensing mirror temperature as heating parameters and prevents the minute surface superheating phenomenon, so not only dispersing fog is automatically convenient but also do not waste electric energy.

The beneficial effects of the utility model are: but due to the Anti-fog mirror top antifog LED lamp with gyration, and have the heating automatic control function, be installed to use from mirror and all become convenient, illumination is reasonable, auto-control heating and employing LED lamp have been realized energy-conserving and environment-protective, and light fixture can not tied mist yet.
