下面结合附图对本实用新型的技术方案作进一步的详细说明:如附图所示,本实用新型的物理构成为三大模块:聚光罩3、电子线路板2及电子元件4、后罩1,聚光罩对光线进行方向性和均匀度的调整,电子线路板及电子元件作为本产品的光源,后罩则对聚光罩和电子线路板及电子元件起固定作用,以及作为本产品与灯具固定的介质。 Further in conjunction with the accompanying drawings for the detailed description of the technical solution of the present invention: As shown in the drawings, the present invention is configured physical three modules: polyethylene cover 3, the electronic circuit board 2 and the electronic component 4, the rear cover 1 poly photomask to light adjusting directivity and uniformity, electronic circuit boards and electronic components of the product as a light source, the reticle and cover the poly electronic circuit boards and electronic components from the fixed effect, as well as the product and fixed media lamps. 具体技术详述如下: Specific techniques are detailed below:

1、一体化凸透镜和漫反射聚光罩:该聚光罩3将点光源位于凸透镜的焦点上,点光源经过凸透镜后形成平行光束以及不平整表面对光线进行漫反射,形成完整光源的良好视觉效果,LED点光源在凸透镜的焦点上经过凸透镜后形成一束束同方向的平行光束,增强了光线的方向性和视觉强度,不平整表面对光线的漫反射使LED点光源在视觉上为一个均匀的平面光源,而不是一个个离散的点光源,具体结构是:聚光罩正面为一个个均匀分布的凸透镜,聚光罩背面为网纹状,凸透镜要尽可能设计大一些,主要目的是使通过聚光罩的每一束光束面积尽可能的大,在视觉上感觉没有光线的面积最小,而视觉上没有光线的位置则由聚光罩背面的网纹漫反射进行补充。 1, the integration of a convex lens and the diffuse reflection poly mask: the poly mask on the focal point light source 3 is located in the convex lens, the convex lens of the light source after the light diffusely reflected parallel beam and forming an uneven surface, a good source of complete visual effect, LED light source is formed parallel beam bundles in the same direction after the focus lens on the lens, the light directivity and enhanced visual intensity, uneven surface to diffuse light in the LED point light source is a visually a uniform planar light source, rather than a discrete point sources, the specific structure: poly reticle uniformly distributed positive for a convex lens, the rear surface is wavy poly mask, designed to be larger as the convex lens, the main purpose is each area of ​​the one beam passing through the reticle polyethylene as large as possible in the light of the visual sense no minimum area, and no light is visually by the position of the reticle back surface textured poly diffuse reflection supplement.

2、光源与凸透镜的一一对应关系结构:电子线路板2及电子元件4(即LED发光管)和聚光罩3在结构位置上一一对应,即电子线路板2上的LED发光管4与聚光罩3上的凸透镜一一对应,每一个LED发光管都对应一个凸透镜,并且LED发光管的发光点均位于聚光罩上对应凸透镜的焦点上,使LED点光源经过凸透镜后形成一束平行光束。 2, the light source and the lens-one correspondence between the structure: two electronic circuit boards and electronic components 4 (i.e., LED light tube) and poly 3-one correspondence reticle position on the structure, i.e., 4 LED light tube on the electronic circuit board 2 and the convex lens 3 on the polyethylene mask one correspondence, each LED corresponds to a convex arc tube, the arc tube and the LED light emitting points are located on the focal point corresponding to the condensing lens to cover the LED light source after the formation of a lens parallel beam bundle.

3、具有新老型号互换性的模块化结构:聚光罩、电子线路板及电子元件和后罩这三个物理实体构成LED交通信号灯,由于以前的很多交通路口需要改造,考虑改造的方便和尽可能的降低成本,因而把LED交通信号灯设计成模块式产品,改造旧交通信号灯时,只要把旧交通信号灯内的白炽灯及灯罩取下,换上LED交通信号灯即可。 3, old and new models with interchangeable modular structure: Poly reticle, electronic circuit boards and electronic components and the rear cover three physical entities constituting the LED traffic signal, because many of the former need to transform the traffic intersection, convenient to consider the transformation and when to reduce costs as much as possible, so that the LED traffic lights designed as a modular product, transforming the old traffic lights, as long as incandescent lamps and lampshades in the old traffic lights removed and replaced with LED traffic lights can be.

4、非对称和旋转定位结构:聚光罩上四个与后罩连接的定位固定柱,电子线路板的缺口、后罩上与聚光罩定位固定柱相对应的定位固定孔和与电子线路板缺口相对应的定位肋为非对称定位结构;后罩上用于与灯具连接的固定孔为旋转定位结构。 4, and the rotation asymmetric positioning structure: four posts positioned and fixed converging cover and the rear cover connected cutout electronic circuit board, after cover is positioned and fixed with a poly reticle posts corresponding positioning hole and fixing the electronic circuit the notch plate corresponding positioning rib asymmetric positioning structure; the lamp cover fixing holes for connecting the rotational positioning structure. 上述的非对称定位结构为生产安装提供了无需调整的方便,而旋转定位结构则有利于多相位灯(箭头灯)产品减少型号,方便生产。 The above-described asymmetrical structure is positioned to provide a convenient production installation without adjustment, and the rotary positioning structure is advantageous for a multi-phase lamp (light arrow) reducing the product model, to facilitate the production. 对于左转、直行、右转交通信号灯均可采用本实用新型的相同型号产品旋转安装定位即可。 For turn left, go straight, turn right at the traffic lights using the present invention may be the same type of product positioning can be swivel-mounted.
