Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is further described.
As Figure 1-4, a kind of blind area Warning indicator for automobile outer rear-view mirror, including mirror supporting plate 5, it is arranged on
Looking glass 1 on mirror supporting plate 5 and indicator, described indicator is by for launching the light source assembly of instruction light source and by transparent base
Material is made and for being constituted to the light guide plate 3 of minute surface tag slot by instruction source reflection, described light source assembly by pcb board 4 and
The multiple LED lamp bead 6 being arranged on pcb board 4 form, and described mirror supporting plate 5 is provided with for accommodating described light source assembly and leads
The installation cavity 5.1 of tabula rasa 3；It is characterized in that: on described light guide plate 3, be provided with the multiple wedge shape boss arranged along axis y side by side,
And the side of each wedge shape boss is equipped with the straight end face 3.4 for matching with corresponding LED lamp bead 6, certain adjacent certain
The upper surface of two wedge shape boss is the arc surface I that radius is R1 epirelief, and the upper surface of outermost wedge shape boss is by substantially
The flat face 3.5 that be arranged in parallel with minute surface and arc surface II composition that radius is R2 epirelief, and R2 > R1.
Described arc surface I is the most transversely provided with, with arc surface II upper surface, the ripple trace that the pitch of waves is equal.So, light guide plate
Reflection be more uniformly distributed, reflecting effect is more preferable.
Described multiple wedge shape boss include first wedge shape boss the 3.1, the second wedge shape boss 3.2 being set up in parallel and are located at
Outermost 3rd wedge shape boss 3.3, the first described wedge shape boss 3.1 and length L1 of the second wedge shape boss 3.2 are equal, and
First wedge shape boss 3.1 and the second wedge shape boss 3.2 upper surface are equipped with the arc surface I that radius is R1 epirelief；Described the 3rd
The cross section of wedge shape boss 3.3 is sector, and length L2 of the 3rd described wedge shape boss 3.3 is more than L1.So, three wedge shapes are convex
The layout of platform is the most reasonable, and structure closely, reflects highly uniform, and the 3rd wedge shape boss 3.3 not only extends illumination
Region, and optimize the angle of emergent light, add a range of light-emitting uniformity, can meet should in terms of driver's angle
Emergency warning lamp should be the brightest, requirement that should be the darkest in other angles, and alarming effect is more preferable.
The width a of the end edge of the side of the close LED lamp bead 6 of the 3rd described wedge shape boss 3.3 is more than the end of opposite side
The width b on limit.As such, it is possible to effectively extend the region of illumination, optimize the angle of emergent light.
The side of described light guide plate 3 is extended with the first installation portion 3.6 for matching, and described with pcb board 4
The ending vertical of one installation portion 3.6 is provided with the second installation portion 3.7 for matching with binding post 7.So, whole assembly
Structure is the compactest, easy to assembly.
Corresponding minute surface mark it is additionally provided with on heating plate 2, and described heating plate 2 between described mirror supporting plate 5 and looking glass 1
The position in district is provided with through hole 2.1.So, printing opacity is easily facilitated.
The inwall of the installation cavity 5.1 of described mirror supporting plate 5 is provided with the convex tendon 5.2 for matching with light guide plate 3.So,
The installation of light guide plate is the most firm, is not susceptible to play, and emergent light is stable.
As it is shown in figure 5, optics indicating range schematic diagram, it can be seen that for left mirror at 60 ° at position of driver
～the instruction brightness requirement height in 75 ° of angles, high for right mirror instruction brightness requirement in 50 °～65 ° of angles.For left and right
Mirror brightness requirement in the angle of 120 °～140 ° is the highest.
Test result as shown in Figure 6 uses the light guide plate of above-mentioned material, and it can meet should in terms of driver's angle
Emergency warning lamp should be the brightest, requirement that should be the darkest in other angles.Specifically, it can meet, for left mirror at 60 °～75 °
Original intensity is met more than 5000cd/m in angle2, more than 3500cd/m after 30 minutes2Requirement.For right mirror at 50 °～65 °
Original intensity is met more than 5000cd/m in angle2, more than 3500cd/m after 30 minutes2Requirement.For left and right mirror at 120 °～
The angle planted agent of 140 ° meets less than 500cd/m2Brightness requirement.And test result of the present utility model is the most excellent.
As it is shown in fig. 7, much better than the measured result of prior art products of this utility model, it can meet from driver angle
Degree sees that this emergency warning lamp should be the brightest, requirement that should be the darkest in other angles.
Below only most preferred embodiment of the present utility model is described, but is not to be construed as the limit to claim
System.This utility model is not only limited to above example, and its concrete structure allows to change.All in this utility model independent right
The various changes made in the protection domain required are all in this utility model protection domain.
