The light source unit includes a power source that supplies power to the light source.

  FIG. 7 shows a perspective view of a road sign cone equipped with a power supply unit (0701). The power supply unit is installed near the tops of the cone body (0702) and the cone cover (0703). In FIG. 7, as an example, a road sign cone using a solar cell (0704) as a power source is shown.

  The “power supply unit” includes a light source and a battery for supplying power to the light source. The light source arranged in the battery unit is a light bulb, a fluorescent lamp, an LED, or the like. The power supply to the light source may be supplied from the outside in addition to a storage battery, a dry battery, or a solar battery. When power is supplied from the outside as a power source, it is not necessary to arrange a storage battery, a dry battery, a solar battery, or the like in the light source unit. In addition, when power is supplied to the light source by a solar battery, a storage battery for storing the power generated by the solar battery is arranged assuming that power generation by the solar battery cannot be performed for a long time such as at night. In addition, when a large amount is used in outdoor road construction or the like, it is troublesome to turn the power on and off one by one. Therefore, an illuminance sensor or the like for automatically detecting the brightness may be disposed in the power supply unit, and the power supply may be automatically turned on or off depending on the illuminance.

  FIG. 8 shows an enlarged view of an example of a power supply unit in which the power source is a solar cell (0801). The power supply unit is covered with a transparent cover made of resin (0802), the upper part is a solar battery, the lower part of the solar battery is a storage battery (0803) for storing power supplied from the solar battery, and the vicinity of the outer periphery of the power supply unit A large number of LEDs (0804) are arranged in the downward direction. The LED is arranged in accordance with the concave groove of the cone body in which the power supply unit is mounted. In addition, an illuminance sensor (0805) for automatically turning on the LED is mounted.

  As shown in FIG. 8, the “light source” is configured to be supplied with power from the power supply unit, and is configured to be disposed between the cone body and the cone cover in accordance with the concave groove of the cone body. Has been. Specifically, the light source is arranged in the power supply unit, and when the power supply unit is mounted on the road sign cone, the light source is arranged near the center of the concave groove of the cone body. The light source may be a light bulb in addition to the LED, but an LED with low power consumption is preferable when power is supplied from a solar cell. When an external power source is used, there is no problem even with a light bulb or the like, but wiring from the power source to the road sign cone is required up to each road sign cone. When the power source is a solar cell, no wiring is required, so the road sign cone can be placed at any position without being affected by the position or length of the wiring.

  Note that the power supply unit and the cone cover may be configured integrally in consideration of electric leakage due to rainwater or the like, or may be separately configured in consideration of maintainability.
