Abstract
The purpose of this utility model is to provide a kind of car light light guide of big light-emitting area, light sends into optical alignment face from light source and is collimated, light is turned down by reflecting surface afterwards, beat afterwards and turned back to direction of traffic on the flank of tooth, reflecting surface cooperates with the flank of tooth, the flank of tooth is cambered surface on top, by adjusting radian, can eventually pass through even light and homogenized in face of light and realized light distribution requirements with controlled level direction lighting angle, the photoconductive surface for realizing large area lights；The utility model is simple and compact for structure, realizes greater area of light extraction, and uniform in light emission, modern design, and bring more technology senses to car light.
Description
Technical field
The utility model is related to automobile lamp signal lamp field, more particularly to a kind of big light-emitting area for signal lamp
Car light light guide.
Background technology
Automobile lamp technology is maked rapid progress, requirement to signal lamp also from most original it is single meet suggesting effect, to existing
Also to meet the novel esthetic requirement of air attractive in appearance.And to moulding and light the requirement more and more higher of effect.It is most common
Signal lamp be bulb reverberation bowl formula, its light-emitting area is big, but its center filament position, speck, uniformity of luminance easily occurs
Influenceed by light-emitting area.And the restriction of the other conditions such as calorifics is received, the signal lamp of bulb reverberation bowl formula is gradually decreased.Take and generation
Be the cylinder light guide formula signal lamp for occurring in the last few years.It is handsome in appearance uniform with its, receive main frame manufacturer and consumer
Welcome.But the luminous width of cylinder light guide receives the limitation of its post diameters, it is more difficult to realize efficient output.
Utility model content
To solve the above problems, the utility model provides a kind of car light light guide of big light-emitting area, and light sends from light source
Collimated into optical alignment face, light is turned down by reflecting surface afterwards, beaten afterwards on the flank of tooth to direction of traffic
Turn back, reflecting surface cooperates with the flank of tooth, the flank of tooth is cambered surface on top, by adjusting radian, can be luminous with controlled level direction
Angle, eventually passes through even light and is homogenized in face of light and realized light distribution requirements, and the photoconductive surface for realizing large area lights.
The purpose of this utility model is to provide a kind of car light light guide of big light-emitting area, includes optical alignment face, described
Optical alignment face right-hand member is optical coupled face, and three light sources are arranged with optical coupled face；The optical alignment face left end is down
45 ° is the reflecting surface of 45mm；Inner side is the flank of tooth below the reflecting surface, and it is even smooth surface that flank of tooth outside is located at below reflecting surface.
Further improvement is that：The optical alignment face width 30mm, thickness is 6mm.
Further improvement is that：The grid array cambered surface that the even smooth surface outside is provided with 2mmx2mm provides even light and expires
Sufficient luminous intensity distribution.
Further improvement is that：The flank of tooth upper horizontal part is cambered surface, and the radian of cambered surface is adjustable such that it is able to control
Lighting angle processed.
The beneficial effects of the utility model：Light sends into optical alignment face from light source and is collimated, afterwards by anti-
Penetrate face light turns down, beat turned back to direction of traffic on the flank of tooth afterwards, reflecting surface cooperates with the flank of tooth, the flank of tooth is on top
It is cambered surface to hold, and by adjusting radian, can be eventually passed through even light and homogenized in face of light with controlled level direction lighting angle
And light distribution requirements are realized, the photoconductive surface for realizing large area lights；The utility model is simple and compact for structure, realizes more large area
Light extraction, and uniform in light emission, modern design, and more technology senses are brought to car light.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Fig. 2 is perspective view of the present utility model.
Wherein：1- optical alignment faces, the optical coupled faces of 2-, 3- light sources, 4- reflectings surface, the 5- flank of tooth, the even smooth surfaces of 6-, 7- grids
Array cambered surface.
Specific embodiment
In order to deepen to understanding of the present utility model, below in conjunction with embodiment, the utility model is described in further detail,
The embodiment is only used for explanation the utility model, does not constitute the restriction to the utility model protection domain.
As illustrated in fig. 1 and 2, the present embodiment provides a kind of car light light guide of big light-emitting area, includes optical alignment face 1,
The right-hand member of the optical alignment face 1 is to be arranged with three light sources 3 in optical coupled face 2, optical coupled face 2；The optical alignment face 1
Left end down 45 ° of reflectings surface 4 for 45mm；Inner side is the flank of tooth 5 to the reflecting surface 4 below, and reflecting surface 4 is located at outside the flank of tooth 5 below
Side is even smooth surface 6.The width 30mm of the optical alignment face 1, thickness is 6mm.The outside of the even smooth surface 6 is provided with 2mmx2mm's
Grid array cambered surface 7 provides even light and meets luminous intensity distribution.The upper horizontal part of the flank of tooth 3 is cambered surface, and the radian of cambered surface can adjust
Such that it is able to control lighting angle.
Light is sent into optical alignment face 1 from light source and is collimated, and light is turned down by reflecting surface 4 afterwards,
Reflecting surface 4 cooperates with the flank of tooth 5, and the flank of tooth 5 is cambered surface on top, by adjusting radian, can be with controlled level direction light emitting anger
Degree, eventually passes through even smooth surface 6 and light is homogenized and light distribution requirements are realized, the photoconductive surface for realizing large area lights；This
Example structure is simply compact, realizes greater area of light extraction, and uniform in light emission, modern design, and bring more to car light
Many technology senses.
