Abstract
The utility model discloses an automatic dimming desk lamp, which comprises a control unit, a light sensor and a brightness control unit; the light sensor is used for sensing the light intensity of the environment, and transforming an optical signal into an electrical signal and sending the electrical signal to the control unit; the control unit receives the electric signal, and drives the brightness control unit to change the current in the circuit according to the electric signal, so as to control the light intensity of the desk lamp. The automatic dimming desk lamp provided by the utility model can sense the environment around the desk lamp by setting the light sensor, wherein the control unit can control the light intensity in accordance with the electric signal transformed from the surrounding environment, thereby protecting the eyes of users as well as saving the energy.
Description
Technical field
The utility model relates to a kind of desk lamp, relates in particular to a kind of desk lamp that can be with an automatic light meter.
Background technology
Illuminating ray, the illuminating ray when especially reading too by force or that eyes are produced is tired, cause that easily eyesight descends, particularly to students in middle and primary schools.
Existing lamp dimmer all is that irradiation brightness is adjusted in the moving light modulation of armrest, makes it to reach certain intensity.This mode relies on the judgement of people to the demand luminous intensity fully, and it has been generally acknowledged that Ning Liang is not dark.Because people's judgement is subjective, has some gaps with right normal brightness; So, this mode also can consume the too much energy when may destroying people's eyesight.
The utility model content
Technical problem to be solved in the utility model is: a kind of desk lamp that can be with an automatic light meter is provided, and it can regulate desk lamp brightness automatically according to the luminous intensity of environment.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of desk lamp with an automatic light meter, it comprises control module, optical sensor, brightness adjusting unit; Described optical sensor is converted into optical signal the signal of telecommunication and is sent to described control module in order to the luminous intensity of induced environment; Described control module receives above-said current signal, and according to the electric current in this signal of telecommunication driving brightness adjusting unit change circuit, with the intensity of control desk lamp light.
As a kind of preferred version of the present utility model, described ambient light intensity institute signals converted, be inversely proportional to the intensity of control module control desk lamp light.
As a kind of preferred version of the present utility model, described control module is MCU or is single board computer.
As a kind of preferred version of the present utility model, thereby described brightness adjusting unit is regulated lamplight brightness by the resistance change electric current of change self place in circuit.
As a kind of preferred version of the present utility model, the form of one ambient light intensity and desk lamp lamplight brightness corresponding relation also is set in the described control module, lamplight brightness is divided into some shelves, in the some shelves of the equal corresponding lamplight brightness of each signal of telecommunication that ambient light intensity transformed one.
As a kind of preferred version of the present utility model, described brightness adjusting unit comprises a whirligig, in order to the manual adjustments lamplight brightness.
As a kind of preferred version of the present utility model, described brightness adjusting unit comprises a brightness selecting arrangement, comprises some brightness options buttons, in order to the manual adjustments lamplight brightness.
The beneficial effects of the utility model are: but desk lamp with an automatic light meter of the present utility model by the ambient conditions of optical sensor inductive desk lamp periphery is set, control module wherein is according to surrounding enviroment institute signals converted control intensity of light; In protection eyes of user health, saved the energy.
Description of drawings
Fig. 1 is the composition schematic diagram of the utility model desk lamp with an automatic light meter.
The specific embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
See also Fig. 1, the utility model provides a kind of desk lamp with an automatic light meter 10, and it comprises control module 11, optical sensor 12, brightness adjusting unit 13; Control module 11 is connected with optical sensor 12, brightness adjusting unit 13 respectively.Described control module is MCU or is single board computer.
Described optical sensor 12 is converted into the signal of telecommunication to optical signal and is sent to described control module 11 in order to the luminous intensity (being brightness) of induced environment; Described control module 11 receives above-said current signal, and drives the electric current that brightness adjusting unit 13 changes in the circuit according to this signal of telecommunication, with the intensity of control desk lamp light.Thereby described brightness adjusting unit 13 changes electric current adjusting lamplight brightness by the resistance of change self place in circuit.Described ambient light intensity institute signals converted, be inversely proportional to the intensity of control module control desk lamp light.The ambient brightness of desk lamp periphery is bright more, and the intensity of light of desk lamp is weak more; The ambient brightness of desk lamp periphery is dark more, and then the intensity of light of desk lamp is strong more.
The form of one ambient brightness and desk lamp lamplight brightness corresponding relation can also be set in the described control module 11.As lamplight brightness being divided into 10 shelves, one in 10 shelves of the equal corresponding lamplight brightness of each signal of telecommunication that ambient brightness transformed.
In the present embodiment, brightness adjusting unit 13 all right manual adjustments; As a whirligig is set, a brightness selecting arrangement perhaps is set,
In sum, but desk lamp with an automatic light meter of the present utility model by the ambient conditions of optical sensor inductive desk lamp periphery is set, control module wherein is according to surrounding enviroment institute signals converted control intensity of light; In protection eyes of user health, saved the energy.
Here description of the present utility model and application are illustrative, are not to want with scope restriction of the present utility model in the above-described embodiments.Here the distortion of disclosed embodiment and change are possible, and the various parts of the replacement of embodiment and equivalence are known for those those of ordinary skill in the art.Those skilled in the art are noted that under the situation that does not break away from spirit of the present utility model or substantive characteristics, and the utility model can be with other forms, structure, layout, ratio, and realize with other elements, material and parts.Under the situation that does not break away from the utility model scope and spirit, can carry out other distortion and change here to disclosed embodiment.
