Penetrate the scattering netted dot of site or wedge shape.
In present embodiment, due to using symmetric double light source（Include the first illuminating part 130 and the second illuminating part 140）, two
The characteristics of attenuation curve of individual light source should meet balance attenuation, the Overlay of two such light source can obtain uniform defeated
Light extraction.
It is to be appreciated that the attenuation curve of single light source：
P(x)=P0e-cx
Wherein, C is the density of scattering netted dot.Consider the factor in terms of technique and processing, uniform density can be used.
Scattering netted dot maximal density is：
Cmax=lg(1-PC/P0)/xmax
Wherein, PC is that transmission of materials light loss is relevant with material, and xmax is light guide plate length.
The size for scattering network interface card is the smaller the better in principle.It is contemplated that technology difficulty, typically left in 0.01 ~ 0.007mm
The right side.
In one embodiment, the density that the scattering netted dot 108 is distributed on the light reflection surface 106 can with light source
The change of distance and change.It is preferred that during due to neighbouring illuminating part, luminous flux is larger, the density that the scattering netted dot 108 is distributed
Can be smaller；And during away from illuminating part, luminous flux is smaller, the density that the scattering netted dot 108 is distributed can suitably increase, and then can make
The light extraction for obtaining the guiding device 10 is more uniform, can reduce it because of the influence brought with illuminating part distance.

Filter circuit.The low-pass filter circuit is used to carry out low-pass filtering operation to the control signal, to cause the driving core
Piece U1 feedback pin FB receives linear control signal.When receiving linear control signal, the driving chip U1
Can the first luminous light of the first illuminating part 130 described in Linear Control, may be such that output is more stable, ensureing what efficiency was utilized
Under the premise of so that the stroboscopic of light is lower.
In present embodiment, the switching signal can be 0,1 switching signal.For example, when the switching signal is 0,
Represent the driving chip U1
In present embodiment, the support member 60 can be aluminium base, and the support member 60 can be additionally used in the heat produced to illuminating part
Amount is radiated.
The heat abstractor 50 includes two fin 503.Two fin 503 sets the side of two support members 60 respectively
Face.Specifically, the fin 503 may include the contact surface 505 extended downwardly.The contact surface 505 of the fin 503 can be with
The side of the support member 60 is in contact, and when the fin 503 is in contact with the support member 60, the fin
503 are located at the lower section of correspondence illuminating part, to be radiated to the heat that illuminating part is produced.The contact surface 505 of the fin 503
Available for expansion area of dissipation.In present embodiment, the heat abstractor 50 also includes two heat conductive silica gels 505.Each thermal conductive silicon
Glue 505 is arranged between correspondence fin 503 and support member 60, to transmit the heat of the fin 503.In other embodiment party
In formula, the heat abstractor 50 can only include the fin 503, in this way, the fin 503 can be supported directly with corresponding
Part 60 is contacted, to realize distributing for heat.In present embodiment, coordinate by using aluminium base and fin and heat conductive silica gel
Radiating mode, makes the fast export as far as possible of heat that luminous original paper produces, and structure takes into account difficulty of processing and area of dissipation as follows.Dissipate
Fin material is the low material of thermal resistance, can be aluminium, also or be copper.
Above-mentioned guiding device and vanity mirror with the guiding device by setting luminous respectively at the two ends of light guide body
Body, and then the light that distribution body of light is produced is transmitted in opposite directions by the different ends of light guide body, reach the equal of lifting emergent ray
The purpose of evenness.In addition, by setting light reflecting device in the light reflection surface for closing on light guide body and setting soft in light-emitting face
Electro-optical device, is conducive to the uniformity of further increase emergent ray.
