Surround it with a reflective surface and cover the top of the light-emitting diode with a translucent cover,
Since the light guide portion integrally formed on the light transmitting cover is brought into contact with the light reflecting surface of the reflector, the light of the light emitting diode can be scattered by the light reflecting surface of the reflector and the light transmitting cover. Thus, it is possible to make the light emission form close to the surface light emission, and when the light emitting device is installed on the ground surface or the outer wall of a building, the traffic light can be visually recognized by a visitor very easily. Furthermore, since the light guide part of the translucent cover is in contact with the light reflecting surface of the reflector, it is possible to disperse the stress even when a load is applied to the translucent cover and to firmly support it, which is excellent in reliability. It is possible to provide a light emitting device.
