Abstract

一种使汽车内饰背景光源均匀的标识面板,包括带有数字,或字符,或标识的标识面板和标识面板后的LED光源,其结构要点在于:标识面板的内侧增加一弧面。本实用新型优点在于,扩大了LED光源照射范围,使汽车内饰用标识显示更均匀。

Description

一种使汽车内饰背景光源均匀的标识面板
所属领域
本实用新型涉及的是汽车内饰用标志面板,尤其是使汽车内饰背景光源均匀的标识面板。
背景技术
现有技术中,汽车内饰:仪表盘、中控台上的数字、字符和标识能显示更醒目,都用LED作为背景光源,不仅达到突出显示的效果,并且使汽车内饰美观。但由于LED的发光特性是发射角度越小,亮度越大。LED照射的最佳发射角度A是30度,如图1所示。因此LED照射到标识面上达到最佳显示效果的范围受到限制。当所要照亮的标识面超出LED照射范围时,显示亮度就不均匀。为了增大照亮范围,如果增加LED到标识面的间隔距离,虽可扩大照射范围,达到一定的效果,但该方法用于汽车内饰上显然是存在一定难度的。
实用新型内容
本实用新型的目的在于克服现有技术的不足之处而提供一种使汽车内饰背景光源均匀的标志面板。
本实用新型是通过以下途径来实现的:
汽车内饰背景光源均匀的标志面板,包括带有数字,或字符,或标识的标识面板和标识面板后的LED光源,其结构要点在于:标识面板的内侧增加一弧面。
这样,标识面板中间的厚度加厚,通过光线反射、折射,减少中间的光线的透过率,避免了中间光线过于集中。这样,光线向标识面板薄的部位扩散,扩大了照射面,达到标识面亮度均匀的效果。
本实用新型可以进一步具体为:标识面板内侧的弧面高度为0.1-0.3mm。
这样,汽车内饰标识面亮度可控制在4±0.8cd/m2   
附图说明
图1是LED光线发射示意图
图2是本实用新型结构示意图
下面结合实施例对本实用新型做进一步描述。
具体实施例
最佳实施例:
如图2,汽车内饰背景光源均匀的标识面板,包括带有数字的标识面板1和标识面板后的LED光源2,其标识面板的内侧弧面高度为0.2mm。
本实用新型未述部分与现有技术相同。
