An existing dome light control mode is redesigned, intelligent detection and control are achieved, whether a person lies on the back or not is judged by achieving intelligent detection below the dome light, then the coverage proportion of the eyelids to the pupils is detected, and therefore real-time intelligent adjustment is achieved for working of a light source, the illumination brightness of the dome light can be automatically adjusted along with feeling of the human eyes. The whole design method takes the comfortable feeling of the eyes of users into full account in the designing process, and the humanized design concept is embodied.
Description
Technical field
The present invention relates to a kind of ceiling light illuminates autocontrol method, belong to light source technical field of automatic control.
Background technology
Lamp is a kind of common illuminations, with the continuous development of technology and the continuous improvement of living standard, lamp
There is earth-shaking change, whether outer shape, or function, the design of lamp is all being constantly modified, continuous quilt
Innovation, to meet people to use, to requirement attractive in appearance, and the continuous improvement that this trend requires with people is also continuing
, such as the patent No.：201220177191.5, disclose a kind of ceiling lighting, including ceiling lighting body and ceiling frame, described
Ceiling sets up the installation portion being equipped with for being installed on described installation site, and the side bending to described ceiling lighting body, and
For the kink being connected with described ceiling lighting body；The ceiling lighting of technique scheme design, will be inhaled by installation portion
Upper frame is installed on installation site, then connects the kink of ceiling lighting body and ceiling frame, that is, achieves the peace of ceiling lighting
Dress, compared with prior art, need not remove the light fixture cover of ceiling lighting in the installation process of ceiling lighting, simplify lamp affixed to the ceiling
The installation of tool；Meanwhile, this ceiling lighting need not arrange mounting flange, and that is, the profile of ceiling lighting body need not change so that inhaling
The transport of washer luminaire is more convenient, and above prior art is directed to transport and the installation just Curve guide impeller of ceiling lighting, allows reality to answer
With convenient.
Also has number of patent application：201210217170.6, disclose a kind of ceiling lamp attachment structure, for hanging ceiling lamp
It is contained on attachment, the periphery of ceiling lamp is provided with flange, and ceiling lamp attachment structure includes at least two fixtures, is evenly spaced in
The surrounding of ceiling lamp；Backing pin, along itself being in axial sliding connection in fixture, its one end is away from attachment one for gear in flange
The screens end of side, and end face is inclined-plane；And elastic component, it is arranged between fixture and backing pin, for limiting backing pin to away from hanging
Slide in the direction of ceiling light；First fixture is fixed on attachment, then by ceiling lamp upwardly, using the edge of ceiling lamp
With the cooperation on inclined-plane, backing pin is made to move to the direction away from ceiling lamp；When flange moves to the top of backing pin, in elastic component
Under elastic force effect, screens end moves to the lower section of flange, completes the installation of ceiling lamp；When pulling down ceiling lamp, make backing pin to away from
The direction of ceiling lamp is moved, and staggering flange in screens end, can take off ceiling lamp, easy installation and removal is quick.Technique scheme
Installation for pendent lamp proposes specific attachment structure, for improving the installation of existing pendent lamp, allows actual installation process more
Convenient.
Moreover, the patent No.：201210253729.0, disclose a kind of LED lamp affixed to the ceiling, including lamp affixed to the ceiling light fixture, inhale
Ceiling light light fixture includes ceiling lamp pedestal and radiator, and ceiling lamp pedestal is provided with bulb installation interface, and bulb installation interface sets
There is radiator；The centrally disposed installation interface of bottom radiator (AZM) is fixedly mounting LED bulb；This LED lamp affixed to the ceiling heat-sinking capability
By force, structure is simple, low cost, installation, use, safeguard and quickly cheaply facilitate it is achieved that the bulb of LED lamp affixed to the ceiling, light fixture and photograph
Bright control independence in production and use for the product, significantly reduces production link, achieves the mass of production, is conducive to
The application of LED energy-saving illumination product and industrial scale；Above technical scheme is the peace of the radiating by light source and overall lamp affixed to the ceiling
It is filled with handss, improve design so that light source heat radiation ability is higher, overall structure is easier for installation.
Make a general survey of above prior art it can be seen that the improvement that prior art is directed to lamp really covers each face of each side of lamp,
But during actual use, still can find some problems, the design of some impersonalities, update with lamp
With design, the brightness of light source can be conditioned in real work, controls the change of its brightness, but for this function, existing
There is the lamp on market mostly also to rest on the artificial manual work stage, that is, need artificially to be gone by rotation according to the subjective demand of oneself
The brightness that button etc. is directed to light source is adjusted, and is not carried out automatization, and, in actual use, the brightness of light source be mostly with
The higher the better for brightness, and brightness height can improve illumination efficiency, but for some situations, with regard to impersonalityization design, such as pushes up
Lamp, for being illuminated from the top down, with the size in space, people select the light source of different capacity, to adapt to the photograph in space
Bright, but in actual applications, if someone comes back, strong light-source brightness will cause to the eyes of people to stimulate, and allows people to feel
To discomfort, but in this case, existing ceiling light but can not solve, the automatically controlling of impersonality.
