A conventional roof lamp using a filament bulb has a problem that the power consumption of the filament bulb is large and the life of the bulb is short. In addition, the inside of the cover (closed space) is easily heated to a high temperature by the heat of the filament bulb, so that the cover made of plastic is likely to be thermally deteriorated, and there is a problem that the replacement life of the cover is short.
In Patent Documents 1, 2, and 3 described above, although LEDs are used, all of them use conventional LEDs with a very narrow irradiation angle, so that a special configuration or auxiliary member is required for use as an indicator lamp. Thus, there is a problem that the structure of the indicator lamp itself becomes complicated.

  Therefore, the present invention solves the above-described conventional problems, and in a rooftop display lamp using LEDs, it is possible to connect the display cover body to the outside with a simple configuration without using complicated auxiliary members or arranging a large number of LEDs. An object of the present invention is to provide a rooftop display lamp that has a bright transmitted light intensity, and that makes it easy for a user to identify an empty vehicle or the like by lighting the rooftop display lamp. It is another object of the present invention to provide a rooftop indicator lamp that can reduce the thermal deterioration of the display cover body due to heat and can sufficiently extend the life of the display cover body made of translucent plastic or the like.

In order to solve the above problems, a rooftop indicator lamp of the present invention is a rooftop indicator lamp that is installed on a vehicle rooftop such as a taxi and informs an empty vehicle by lighting, and includes a display cover body and a base on which the display cover body is fitted. A light source seating portion provided on the base, and a light source control circuit for controlling the LED of the wide irradiation angle and a light source control circuit for controlling the LED of the wide light irradiation angle. The first feature is that the light emitted from the LED with the wide irradiation angle of the part spreads at a high angle and is transmitted from the inside of the display cover body to the outside.
In addition to the first feature, the wide-angle LED has a flat shape and has a light emitting portion on the top surface, and one or more rooftop indicator lamps of the present invention are mounted on the base. The second feature is that the light source is attached to the upper surface of the light source seat by upward light emission.
In addition to the first or second feature, the rooftop indicator lamp of the present invention has a third feature that the LED having a wide irradiation angle is a high-intensity LED.
Moreover, in addition to any of the first to third features, the rooftop indicator lamp of the present invention has a fourth feature that the light source seating portion is attached with an emergency light that is turned on in an emergency. .

Power consumption can be reduced compared to conventional filament bulbs. In addition, the life of the light source can be extended and replacement can be reduced. In addition, since the generation of heat is small, the thermal deterioration of the cover body is reduced, so that the replacement life can be extended.
Of course, by using LEDs with a high irradiation angle, it is not necessary to arrange a large number of LEDs in a bundle, and a large number of LEDs are arranged compared to a conventional roof lamp using LEDs. There is no need for extra equipment necessary for the display, and no need for equipment such as a reflector for reflecting light emitted from a large number of LEDs in a predetermined direction. It is possible to provide a rooftop indicator light that allows light to pass through a wide range to the outside.
In addition, by installing LEDs with a wide illumination angle, the entire inside of the display cover body can be sufficiently irradiated with a small number, and the entire display cover body can be brightened. Characters and figures can be clearly confirmed from the outside. Of course, it becomes easy for the user to identify an empty vehicle or the like, and the function as an indicator light for a taxi or the like can be improved.

Moreover, according to the rooftop indicator lamp of Claim 2, in addition to the effect by the structure of Claim 1, LED of wide irradiation angle shall have a flat shape, and shall have a light emission part on the upper surface. 1 or more are attached to the upper surface of the light source seating portion on the base by upward light emission,
The flat, wide-angle LED mounted on the upper surface of the light source seating part on the base will be placed at a low position in the rooftop indicator light, and the light emitted upward from the low position is The display cover body can be sufficiently expanded with a sufficient space. Therefore, firstly, the emitted light is sufficiently spread to reach the display cover body, and stable transmitted light can be emitted to the outside from the entire display cover body. Secondly, by setting the position of the LED light emitting part in the rooftop indicator lamp to be sufficiently lower than before, sufficient space can be secured between the LED light emitting part and the display cover body. It is possible to sufficiently suppress the display cover body from being heated to a high temperature by heat generated by light emission. That is, even when a higher-brightness LED is used, it is possible to suppress deterioration of the display cover body due to the heat generated by the LED.

Moreover, according to the rooftop indicator lamp of Claim 3, in addition to the effect by the structure of the said Claim 1 or Claim 2, since LED of a wide irradiation angle is high-intensity LED,
The entire display cover body can be further brightened by the brighter light, and characters, figures, etc. displayed on the display cover body can be seen more clearly from the outside.

Moreover, according to the rooftop indicator lamp of Claim 4, in addition to the effect by the structure in any one of the said Claims 1-3, a light source seating part is attached along with the emergency light to light in an emergency Because
In the event of an emergency such as a burglary in the vehicle, the switch on the driver's seat can flash the rooftop indicator light in red or the like to inform the outside that it is an emergency.
