According to the piano key effect atmosphere lamp light guide structure, a light guide is integrally formed based on the double-shot molding process, the light guide effect is very good, through the alternate design of protruding and light-transmitting white key protrusions and light-proof black key blocking strips, the stereoscopic impression of the overall modeling of the thick-wall light guide is improved, the appearance effect of black and white piano keys is achieved, and the light guide effect is good. The overall aesthetic feeling is further improved by adopting black and white contrast color matching; moreover, by arranging the strip-shaped light receiving and diffusion patterns, light can be received efficiently, the overall brightness of the light guide is improved, light diffusion can be conducted quickly, the overall lighting effect of the light guide is more uniform, meanwhile, every two white key protrusions form a group, each group of white key protrusions is provided with one LED lamp bead, the lighting brightness of the light guide can be guaranteed, and the light guide is more attractive in appearance. According to the utility model, the LED lamp beads are arranged on the white keys, the white keys can be effectively prevented from protruding to generate high-brightness bright spots, the number of the LED lamp beads is reduced by half, the cost is greatly reduced, and the wiring difficulty and the manufacturing difficulty of the PCBA are greatly reduced.

    本发明公开了一种钢琴键效果氛围灯导光结构,光导基于双色注塑工艺一体成型,不仅导光效果非常好,而且通过凸出且透光的白键凸起同不透光的黑键挡条的交替设计,既提升了厚壁光导整体造型的立体感,构成黑白钢琴键的外观效果,又通过采用黑白对比的配色,进一步提升了整体美感;并且,通过设置条形收光扩散花纹,不仅能够高效地收光,提升了光导整体的亮度,而且能够快速地进行扩光,使光导整体的点亮效果更加均匀,同时,每两个白键凸起为一组,每组白键凸起配置一颗LED灯珠,不仅能够保证光导的点亮亮度,而且能够有效避免白键凸起出现高亮亮斑的情况,同时LED灯珠减少了一半的数量,既大幅降低了成本,又大幅降低了PCBA的走线难度和制造难度。
