20150062865 | INDICATING LIGHT FOR TRANSPORTATION - An indicating light for transportation has a circuit board, a reflective layer and a light guide plate sequentially attached. Multiple LEDs are mounted on the circuit board and emit light. The light guide plate has an inner surface and an outer surface, wherein at least one indicating portion is formed on the inner surface for reflecting or refracting light of the LEDs to the outer surface. The reflective layer further prevents light leakage. Therefore, the indication portion generates a surface light effect for reducing glare and providing an enlarged illuminating area. | 03-05-2015 |
