Description
Technical field
The utility model belongs to automobile lamp technical field, is related to automobile room lamp, especially a kind of atmosphere lamp.
Background technique
Automobile atmosphere lamp is a kind of headlamp played role in decoration, can render interior atmosphere, moreover it is possible to improve the class of vehicle, more
It is also become more and more popular come more popular, slowly from luxury car, exclusive characteristic has entered popular car ranks.Currently, vapour
Vehicle atmosphere lamp uses LED light source substantially, and moulding is mostly different elongated shape and panel-shaped, and elongated shape utilizes light guide direct projection more
Or reflection, panel-shaped mostly use greatly scattering material.Panel-shaped atmosphere lamp mostly uses LED direct projection scheme, and uniformity difference is that one is big
Difficult point.To realize uniformly light-emitting, it is necessary to increase LED and panel spacing and arrange LED closeer, the former is limited to whole lamp thickness
Degree, latter increases cost, and when program is lighted still will be obvious that the non-uniform phenomenon of LED location local luminance,
Such uniformity is not able to satisfy the higher and higher evaluation requirement of automobile industry.The high poor diffusivity of scattering material transmitance, thoroughly
It is low to cross the low light efficiency of rate, may require that panel using transparent material, also has more when panel-shaped atmosphere lamp is combined with indoor lamp function
Main engine plants directly require panel using transparent material, at this moment it is contemplated that plus a structure go to block LED direct light, use light guide
Plate is simultaneously designed requirement to realize brightness uniformity to it.
Utility model content

There is the phenomenon that obvious bright wisp and filaments of sun in atmosphere lamp light transmission part when peripheral position is lighted in turn, obtains uniform area source, mentions
Height is incident on the uniformity of the light in lampshade.
Further, there are gaps with decorative circle and lampshade lightproof part respectively for the side wall of the lampshade light transmission part, keep away
Exempt from zero touch zero it is connected when decorative circle and lampshade lightproof part can absorb the light got on side wall in lampshade, to improve light efficiency.
Further, lampshade transmittance section facet is equipped with the decorative pattern tooth that size is identical, spacing is equal, flower when not lighting
Line is evenly distributed on atmosphere lamp transparent area, and decorative pattern tooth can destroy total reflection of the light in lampshade so that light occurs in the position of tooth
Refraction realizes that decorative pattern tooth is uniformly lighted when atmosphere lamp is lighted.
Further, the decorative pattern tooth on the lampshade light transmission part is concave tooth or double wedge, and facewidth 0.1-0.3mm, tooth depth is small
In 0.2mm.
Further, the decorative circle selects the material with reflection characteristic, can increase the overall brightness of atmosphere lamp, can also
Improve uniformity.
Further, the LED light source includes at least one LED lamp bead, and the entering light face of the optical plate is equipped at least
One arcuate structure groove to concave, LED light source described in the arcuate structure groove face and in corresponding layout type,
The light that this layout type can be such that LED light source issues improves optical plate light-emitting surface by spreading when optical plate entering light face
The uniformity of light obtains approximate area source, to improve the uniformity of lampshade decorative pattern tooth when lighting.
