Abstract
The invention aims to provide car lamp light guide with a large light-emitting area. Light enters an optical collimation plane from a light source for being collimated, and then is radiated on a toothed surface to turn back in a travelling direction after being downwards turned back through a reflecting surface; the reflecting surface is mutually matched with the toothed surface; an arc-shaped surface is arranged at the top end of the toothed surface; by regulating radian, a light-emitting angle in the horizontal direction can be controlled; and finally, light is homogenized through a light homogenizing surface, and light distributing requirements are realized, so that large-area light emitting of a light guide surface is realized. The car lamp light guide provided by the invention is simple and compact in structure, realizes light emitting of larger area, is uniform in light emitting, is novel in modeling, and brings more science and technology feelings to a car lamp.
Description
Technical field
The present invention relates to automobile lamp signal lighties field, the car light of more particularly, to a kind of big light-emitting area for signal lighties
Photoconduction.
Background technology
Automobile lamp technology is maked rapid progress, the requirement to signal lighties also from most original single meet suggesting effect, to existing
Also to meet the novel esthetic requirement of air attractive in appearance.And to moulding with the requirement more and more higher of lighting effect.Most common
Signal lighties be bulb reverberation bowl formula, its light-emitting area is big, but its center filament position, speck, uniformity of luminance easily
Affected by light-emitting area.And receiving the restriction of the other conditions such as calorifics, the signal lighties of bulb reverberation bowl formula gradually decrease.Take and generation
Be the cylinder light guide formula signal lighties occurring in the last few years.Handsome in appearance uniformly with it, receive main frame manufacturer and consumer
Welcome.But the luminous width of cylinder light guide receives the restriction of its post diameters it is more difficult to realize efficient output.
Content of the invention
For solving the above problems, the present invention provides a kind of car light photoconduction of big light-emitting area, and light sends entrance from light source
Optical alignment face is collimated, and by reflecting surface, light is turned down afterwards, beats afterwards and turns back to direction of traffic on the flank of tooth,
Reflecting surface is cooperated with the flank of tooth, and the flank of tooth is cambered surface on top, by adjusting radian, can control horizontal direction lighting angle,
Eventually pass through light faced by even light to carry out homogenization and realize light distribution requirements it is achieved that large-area photoconductive surface lights.
It is an object of the invention to provide a kind of car light photoconduction of big light-emitting area, include optical alignment face, described optics
Collimation plane right-hand member is optical coupled face, is arranged with three light sources in optical coupled face；Described optical alignment face left end is for 45 ° down
The reflecting surface of 45mm；Below described reflecting surface, inner side is the flank of tooth, and being located at below reflecting surface outside the flank of tooth is even bright finish.
Further improvement is that：Described optical alignment face width 30mm, thickness is 6mm.
Further improvement is that：The grid array cambered surface being provided with 2mmx2mm outside described even bright finish provides even light and expires
Sufficient luminous intensity distribution.
Further improvement is that：Described flank of tooth upper horizontal part is cambered surface, and the radian scalable of cambered surface is such that it is able to control
Lighting angle processed.
Beneficial effects of the present invention：Light sends entrance optical alignment face from light source and is collimated, and passes through reflecting surface afterwards
Light is turned down, beats afterwards and turn back to direction of traffic on the flank of tooth, reflecting surface is cooperated with the flank of tooth, the flank of tooth on top is
Cambered surface, by adjusting radian, can control horizontal direction lighting angle, eventually pass through light faced by even light and carry out homogenization reality
Existing light distribution requirements are it is achieved that large-area photoconductive surface lights；Present configuration simply compact it is achieved that greater area of go out light,
And uniform in light emission, modern design, and bring more technology senses to car light.
Brief description
Fig. 1 is the schematic diagram of the present invention.
Fig. 2 is the perspective view of the present invention.
Wherein：1- optical alignment face, the optical coupled face of 2-, 3- light source, 4- reflecting surface, the 5- flank of tooth, the even bright finish of 6-, 7- grid
Array cambered surface.
Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment, the invention will be further described, this embodiment
It is only used for explaining the present invention, do not constitute limiting the scope of the present invention.
As illustrated in fig. 1 and 2, the present embodiment provides a kind of car light photoconduction of big light-emitting area, includes optical alignment face 1,
Described optical alignment face 1 right-hand member is optical coupled face 2, is arranged with three light sources 3 in optical coupled face 2；Described optical alignment face 1
Left end down 45 ° of reflectings surface 4 for 45mm；Inner side is the flank of tooth 5 to described reflecting surface 4 below, and reflecting surface 4 is located at outside the flank of tooth 5 below
Side is even bright finish 6.Described optical alignment face 1 width 30mm, thickness is 6mm.It is provided with 2mmx2mm's outside described even bright finish 6
Grid array cambered surface 7 provides even light and meets luminous intensity distribution.The described flank of tooth 3 upper horizontal part is cambered surface, the radian scalable of cambered surface
Such that it is able to control lighting angle.
Light sends entrance optical alignment face 1 from light source and is collimated, and by reflecting surface 4, light is turned down afterwards,
Reflecting surface 4 is cooperated with the flank of tooth 5, and the flank of tooth 5 is cambered surface on top, by adjusting radian, can control horizontal direction light emitting anger
Degree, eventually passes through even bright finish 6 and light is carried out with homogenization and realizes light distribution requirements it is achieved that large-area photoconductive surface lights；This
Example structure simply compact it is achieved that greater area of go out light, and uniform in light emission, modern design, and bring more to car light
Many technology senses.
