Preferably, support bar is preset with the microcontroller, one end of the support bar connects the microcontroller,
The other end is fixed on umbrella-type reflection shield, can pass through the microprocessor control umbrella-type reflection shield contracting Zhang Shiji.
Preferably, the intensity adjustable light fixture also includes a luminance meter, and the luminance meter is fixedly installed on the umbrella
The outer top of formula reflection shield, can measure the brightness of light.
Preferably, a gear is fixedly installed on light source, and a rack is fixed in the lower end of the connecting rod, institute can be made
State umbrella-type reflection shield and light source while adjust.
Preferably, the upper gear of the rack away from undergear away from than for 1 to 0.69.
Compared to the prior art, beneficial effect caused by the utility model is:
The utility model is simple in construction, ingenious in design, by set a microcontroller with support bar, support bar it is another
End is fixed on umbrella-type reflection shield, and umbrella-type reflection shield contracting Zhang Shiji is can control with microcontroller, with the size of adjustment reflection angle
Mode, automatically adjust the intensity of light, reach power saving, and protect the effect of eyesight.

It is some embodiments of the utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the side structure schematic diagram of the utility model embodiment one.
Fig. 2 is the use state of the utility model embodiment one with reference to figure one.
Fig. 3 is the use state of the utility model embodiment one with reference to figure two.
Fig. 4 is the use state of the utility model embodiment two with reference to figure one.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clear, complete description, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on embodiment of the present utility model, those of ordinary skill in the art institute under the premise of creative work is not made
The every other embodiment obtained, belong to the scope of the utility model protection.
Embodiment one
Reference picture 1, Fig. 2 and Fig. 3.A kind of intensity adjustable light fixture, its structure include：One fix bar 21, a connection piece
22nd, a umbrella-type reflection shield 23, a connecting rod 24, a light source 25 and a microcontroller 26.
The upper end of fix bar 21 is fixed on the ceiling, the affixed connector 22 in lower end.
A umbrella-type reflection shield 23 is connected on the connector 22, light source can be reflected, fixes and sets in the lower end of connector 22
A connecting rod 24 is put, and the light source 25 is hung with the end of the connecting rod 24.
The microcontroller 26 is movably arranged on the upper end of the connecting rod 24, is preset on the microcontroller 26
There is support bar 261.One end of the support bar 261 connects the microcontroller 26, and the other end is fixed on umbrella-type reflection shield 23,
The contracting Zhang Shiji of umbrella-type reflection shield 23 can be controlled by the microcontroller 26.
The intensity adjustable light fixture also includes a luminance meter 27, and it is anti-that the luminance meter 27 is fixedly installed on the umbrella-type
The outer top of light shield 23, can measure the brightness of light.
Reference picture 1, Fig. 2 and Fig. 3.When needing illumination, user can open light source 25, and make its light reflective from umbrella-type
The reflection of cover 23 is cast, and the intensity of surrounding environment light can be measured by the luminance meter 27 on the umbrella-type reflection shield 23, and will letter
Number microcontroller 26 is transferred to, if light intensity is too strong, microcontroller 26 will start, and adjust weak current, and drive support bar
261 open umbrella-type reflection shield 23, increase reflection angle, and the light for allowing light source 25 to be cast out is more micro- after reflection
It is weak, too strong light can be adjusted to moderate；On the contrary, if the intensity that luminance meter 27 measures surrounding environment light is more faint
When, microcontroller 26 will also start, strengthening electric current, and drive support bar 261 to allow umbrella-type reflection shield 23 to be condensed, and become reflection angle
It is small, because reflection angle reduce, light becomes more to assemble after reflection, can will too decreased light be adjusted to it is moderate.
Embodiment two
Reference picture 4.The embodiment of the present embodiment is substantially the same with embodiment one, and its difference is, in light source 25
One gear 3 of upper fixed setting, and fixes a rack 31 in the lower end of the connecting rod 24, can make the umbrella-type reflection shield 23 with
Light source 25 adjusts simultaneously.The upper gear of the rack 31 away from undergear away from than being best use effect for 1 to 0.69.
In use, can adjust automatically light intensity, also can power saving, and protect user's eyesight.
The utility model is simple in construction, ingenious in design, the advantage is that, by setting a microcontroller with support bar,
The other end of support bar is fixed on umbrella-type reflection shield, and umbrella-type reflection shield contracting Zhang Shiji is can control with microcontroller, anti-with adjustment
The mode of the size of firing angle degree, the intensity of light is automatically adjusted, reach power saving, and protect the effect of eyesight.
A kind of intensity adjustable light fixture provided by the utility model is described in detail above.It is used herein
Specific case is set forth to principle of the present utility model and embodiment, and the explanation of above example is only intended to help
