Abstract

PROBLEM TO BE SOLVED: To provide a luminous road sign with increased brightness of light emitted to the outside from its light emitting part. SOLUTION: A plurality of luminous units 5, in each of which a light-emitting diode 3 is placed opposite to the focal position of a convex lens 4 so that the light La of the light emitting diode is emitted while being refracted by the convex lens 4 into an almost parallel beam Lb, are aligned to form a light- emitting part 2, with the parallel beams Lb from the luminous units 5 being emitted to the outside from the light emitting part 2. Since the light emitted from the light emitting part 2 is parallel beams Lb, it has higher brightness than conventional diffused light, and since the plurality of luminous units 5 are aligned and the parallel beams Lb matching their number are emitted from the light emitting part 2, the brightness as a whole is greatly enhanced.

2. Description of the Related Art Various road signs are provided on roads to encourage drivers and pedestrians of running vehicles to promote traffic safety or to indicate driving directions. Conventionally, most of such road signs have a retroreflective sheet that is brightly shined by retroreflecting the light when irradiated with light from a headlight or the like in order to enhance visibility at night, and is attached to the surface. It is. However, since the retroreflective sheet does not shine unless light is irradiated, especially in places where traffic is intense, such as places where nighttime visibility needs to be further improved, light emitting diodes such as light emitting diodes and light bulbs are arranged. A self-luminous road sign is provided which emits light from a part to be visually recognized by a driver or a pedestrian of a vehicle.

As described above, in the self-luminous road sign, the light emitted from the light-emitting part to the outside is visually recognized by the driver or the pedestrian of the vehicle. If the value is low, the visibility decreases. In particular, since the light from the self-luminous body is diffused and emitted radially, if the light emission luminance is low, the visibility from a distance is extremely reduced. Therefore, in order to increase the light emission luminance, various measures have been taken such as increasing the light emission luminance by flowing a large amount of current through the self-luminous body, or increasing the size of the self-luminous body. However, when a large amount of current is applied to the self-luminous body, a long load is applied to the self-luminous body, so that the life is shortened. Further, since a large amount of current is consumed, a commercial power supply is required and the solar cell cannot be used. Therefore, there is a problem that the installation place is limited. On the other hand, if the self-luminous body is made large, there is a problem that the road sign itself becomes large and the cost increases.
