Description
Technical field
This utility model relates to light-use field, particularly relates to a kind of light modulating device.
Background technology
In school, the when of often there is daytime, draw the curtain together and but open the situation of daylight lamp in classroom, and winter is this existing
As becoming apparent from.Obviously do so wastes substantial amounts of electric energy.Tracing it to its cause, if being because giveing up the curtain, sunlight can direct projection
The classmate in south on the face or desktop, no matter which kind of situation, they can feel the most dazzling, it is therefore desirable to draws the curtain together；But draw
After upper curtain, the brightness in classroom is inadequate, so daylight lamp to be opened.This shielding nature light is but wasted the energy and is used artificial
The way of light is the most unscientific, therefore devises a kind of classroom automatic light control system.
Utility model content
The purpose of this utility model is to provide a kind of simple in construction, light modulating device easy to use, can effectively and reasonably
Utilize natural energy resources, environmental protection and safety.
To achieve these goals, the technical solution of the utility model is:
A kind of light modulating device, including framework, reflector and driving means, described driving means drives described reflector to turn
Dynamic；Described reflector is connected on said frame by rotary shaft；Described driving means includes gear, power supply and motor, institute
State power supply and provide power supply for motor, pinion rotation described in described motor-driven；Described gear is connected to described rotary shaft, drives
Dynamic described rotary shaft rotates, and then drives described reflector to rotate.
Further, described power supply includes solar panel and accumulator.
Further, described power supply is supplied to described motor after double-direction control switch is connected to voltage changing module transformation,
Described gear is arrived in the output after timing gear wheels regulation moment of torsion and rotating speed of the power of described motor output.
Further, described reflector is multiple, and the quantity of described gear is identical with the quantity of reflector, is respectively used to drive
Dynamic corresponding reflector rotates, and is connected by chain between multiple described gears.
This utility model has the advantage that relative to prior art
This utility model, by regulating the angle of reflector, makes the sunlight shining on reflector reflex to the roof of indoor
On, then the diffuse-reflectance through roof illuminates classroom uniformly, thoroughly solve position near the window due to direct projection brightness too high, away from window
The situation of the position luminance shortage at family.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
Refer to Fig. 1, a kind of light modulating device, including framework 1, reflector 2 and driving means, described driving means drives
Described reflector 2 rotates；Described reflector 2 is connected on described framework 1 by rotary shaft 3；Described driving means includes gear
4, power supply and motor 9, described power supply provides power supply, described motor 9 to drive described gear 4 to rotate for motor 9；Described tooth
Wheel 4 is connected to described rotary shaft 3, drives described rotary shaft 3 to rotate, and then drives described reflector 2 to rotate.
Preferably, described power supply includes solar panel 6 and accumulator 12.
Preferably, described power supply is supplied to described motor 9 after double-direction control switch 7 is connected to voltage changing module 8 transformation,
The power of described motor 9 output exports described gear 4 after timing gear wheels 10 regulate moment of torsion and rotating speed.
Preferably, described reflector 2 is multiple, and the quantity of described gear 4 is identical with the quantity of reflector 2, is respectively used to
Driving corresponding reflector 2 to rotate, connected by chain 5 between multiple described gears 4, the size of reflector 2 and quantity are by frame
Frame 1 determines to distance and the window areas of window, just blocks whole window when reflector 2 is all in vertical direction, and anti-
Window can not be encountered when tabula rasa 2 is vertical with framework 1.
Preferably, described voltage changing module 8, motor 9 and gear teeth wheels 10 are provided above rain cover.
When this utility model uses, power supply being that reflector 2 is powered, many set reflectors 2 can be with public a set of electric supply installation.
During use, by controlling the angle of switch-mode regulation reflector 2, make to shine the sunlight on reflector 2 and reflex on the roof of indoor,
Classroom is illuminated in diffuse-reflectance through roof uniformly again, do not have position near the window due to direct projection brightness too high, away from window
The situation of position luminance shortage.If needing to use multimedia equipment, then can completely close all or part of reflector, than
Curtain effect is more preferable.If system is in electroless state, a manually adjustable reflector, other reflector will same step
Joint.
What this utility model can avoid that present classroom generally exists draw the curtain together turn on light this waste energy helpless it
Lift.Meanwhile, compared to hanging curtain, this dimming mode can reflect more sunlight winter enters the classroom；Summer then well-ventilated,
Can effectively reduce classroom temperature, have energy-conservation effect equally.Sunlight and the health to student of ventilating also are beneficial to.
This utility model simple in construction, solar panel is powered and can be avoided connecing indoor power supply, environmental protection and safety, indoor
Only two-way switch, takies the interior space the least.
This utility model simple in construction, easy to use, natural energy resources, environmental protection and safety can be utilized effectively and reasonably.
