Seat 1 arranges multiple photophores 2 positioned at different physical locations, each photophore 2 and light for positioning support in mounting base 1
The relative position learned between part is different from.
Optical element is used cooperatively with photophore 2, and the light that photophore 2 emits is reflected or reflected by optical element, positioned at not
It is different with the incidence angle between the light and optical element of the photophore 2 of physical location, by the physics characteristic of light it is found that light passes through
It crosses the refraction angle after optical element and angle of reflection is just different, therefore the light that the photophore 2 for being located at different physical locations emits is through light
Different light paths or distribution curve flux are formed after learning part refraction or reflection；Light path is the irradiating angle of light, and distribution curve flux refers to sky
Between all directions light distribution；And the luminance independent control of the corresponding each photophore 2 of same optical element, Mei Gefa
Whether light device 2 shines and the size of brightness can be adjusted individually, is not associated between other illuminating parts.
The utility model passes through the shooting angle of luminance light regulating that cooperates between different photophores 2；Light
It learns part and is generally centrosymmetric structure, if the photophore 2 at face optical element center shines, and the photophore of other positions is not sent out
Light, then emergent ray do not deflected towards front；Or the photophore 2 and other positions at face optical element center are in symmetrical
The photophore 2 of distribution shines simultaneously, then light is still towards front, but distribution curve flux is different.If it is only deviating from optical element
The photophore of the heart shines, and the photophore of other positions does not shine, then emergent ray is deflected towards the opposite direction of center line, example
If the optical element only positioned at central right shines, then the light by optical element outgoing is deflected towards left side, light after deflection
Light path and distribution curve flux be different from, have the function that adjust light path and distribution curve flux.The adjusting process of light only relates to more
The change of a itself working condition of photophore 2, does not have mechanical adjustment process, therefore would not wear, remains higher
Precision；Do not include motor in overall structure, can greatly save space, effectively compress the volume of big lamp group, set for other
It is standby to reserve more spaces.
