In the description of the invention, it is to be understood that term " perforate ", " on ", " under ", " thickness ", " top ", " in ",
Indicating position or the position relationship such as " length ", " interior ", " surrounding ", it is for only for ease of the description present invention and simplifies description, without
It is that the component of instruction or hint meaning or element must have specific orientation, with specific azimuth configuration and operation, therefore not
It is understood that as limitation of the present invention.
As shown in figure 1, the invention provides a kind of down straight aphototropism mode set based on compound reflecting bowl, including by some squares
The horizontal and vertical reflector matrix rearranged of shape reflector 1, reflector matrix top is provided with diffuser plate 2, two neighboring anti-
Close-packed arrays between light bowl 1, the middle part of reflector 1 are provided with light source 3, light source can be commonly use backlight adopting surface mounted LED, CSP and other
Back light, formed when by the effect of reflector 1 and diffuser plate 2 light that light source 3 is sent can be made to be emitted from diffuser plate 2 uniformly
Area source, it is real by being controlled to the light source 3 in each reflector 1 due to the corresponding light source 3 of each reflector 1
Now to the bright dark control of corresponding region on reflector matrix, truly realize to display screen area controllable function.
As Figure 2-3, the inwall of reflector 1 by two diagonal be divided into four sizes, shape all same three
Angular first reflecting surface 11, the first reflecting surface 11 are the globoidal structure to lower recess, and the light projected to light source 3 reflects.
The middle part of reflector 1 is provided with the rectangular reflection lid 12 of hollow structure, and reflection cap 12 is covered on light source 3, in reflection cap 12
Portion is provided with light hole 13, there is provided the illumination directly over reflection cap 12, the issued section light of light source 3 are emitted directly toward through light hole 13
Diffuser plate 2, then through 2 uniform light extraction of diffuser plate.
The top plate of reflection cap 12 is inverted cone-shaped structure, and top plate lower surface forms the second reflecting surface 14, and the second reflecting surface 14 is
The globoidal structure to arch upward upwards, the top plate for most of light elder generation directive reflection cap 12 that light source 3 projects are anti-through the second reflecting surface 14
The inwall of rear directive reflector 1, then the directive diffuser plate 2 after the reflection of the first reflecting surface 11 are penetrated, is then uniformly gone out through diffuser plate 2
Light.
The side plate of reflection cap 12 is four vertical transparent panels 15, and the issued section light of light source 3 is anti-through the directive of transparent panel 15
The inwall of light bowl 1, the directive diffuser plate 2 after the reflection of the first reflecting surface 11, then through 2 uniform light extraction of diffuser plate.
The light propagation path of the present invention as shown in figure 4, spot light 3 launches light to surrounding, wear by a portion light
Cross light hole 13 and be emitted directly toward diffuser plate 2, then pass through transparent panel 15 before this through 2 uniform light extraction of diffuser plate, another part light
The inwall of directive reflector 1, the directive diffuser plate 2 after the reflection of the first reflecting surface 11, then through 2 uniform light extraction of diffuser plate, and it is big
The top plate of the first directive reflection cap 12 of some light, the inwall of directive reflector 1 after the reflection of the second reflecting surface 14, then through first
Directive diffuser plate 2 after reflecting surface 11 reflects, then through 2 uniform light extraction of diffuser plate, so as to which the light for sending spot light 3 passes through instead
The effect of light bowl 1 and diffuser plate 2 forms uniform area source.
According to actual light extraction needs, phase can be done to the inwall of reflector 1, the top cover of reflection cap 12 and the surface of diffuser plate 2 respectively
The processing answered such as sets site type boss or sets rib strip structure to reach the equally distributed effect of light shape.
The assemble method of down straight aphototropism mode set based on compound reflecting bowl, comprises the following steps：
Step S1, light source lamp bar group is fixed on corresponding position in module shell；
