Description

  The present invention relates to a decorative lamp for a taxi used by being mounted on a taxi roof.

  On the roof of the taxi, an on-roof indicator light (that is, a row lamp) in which a light source is disposed inside a translucent synthetic resin case on which a company mark or the like is displayed is attached.

  This roof lamp not only enables taxi passengers to recognize taxis on the street, but also serves as an advertisement for each taxi company, so each taxi company is molded into a unique shape and used. The company can be appealed to customers.

Conventionally, a lamp using a filament has been used as a light source of a taxi rooftop display lamp. However, the lamp has a problem that the filament easily breaks and must be frequently replaced. For this reason, taxi rooftop indicator lamps have been developed that use low power consumption and long-life LEDs (light emitting diodes) as light sources to replace the lamps (see, for example, Patent Document 1).
JP 2007-114366 A

  By the way, as described above, each taxi company uses a taxi rooftop indicator light that has been shaped into its own shape to appeal to its customers for its own taxi. Even if it is turned on, the brightness is dark compared to the brightness of the taxi headlight, so the difference in the shape of the indicator light on the roof of the taxi is buried, and the appeal effect to the passengers is diminished. there were.

  Here, by attaching a small light source such as an LED to the taxi rooftop indicator lamp and lighting it, it is possible to improve the appeal effect to customers, but it is superior to the brightness of the headlight and attracts customers. In order to perform highly-designed electrical decoration that can be improved, a large number of LEDs must be arranged on the entire surface of the taxi rooftop indicator lamp, and there is a problem that the apparatus becomes complicated and large-scale. It was.

  Moreover, the above-mentioned taxi rooftop indicator lamp using the LED is merely a replacement of the light source from the conventional lamp to the LED, and the effect of attracting customers at night cannot be improved.

  Therefore, the main problem of the present invention is that, although the amount of LED used is small, it is possible to emit light with high design and excellent visibility from a distance, and to improve the effect of attracting customers at night. It is possible to provide a decorative light for a taxi.

  The invention described in claim 1 is described as follows: “A light emitting portion (14) in which a plurality of LEDs (22) are arranged in an arch shape on a plate-like main body (20) made of a transparent synthetic resin; Is formed into an arch shape corresponding to the arrangement shape of the LED (22), and the surface thereof is set to face the light exit surface of the LED (22) and in the optical axis direction of the LED (22). It is composed of one or a plurality of light guide members (18) installed at intervals.

  In this invention, the light emitted from the LED (22) arranged in an arch shape passes through one or more transparent light guide members (18) installed in the optical axis direction of the LED (22). However, at that time, a part of the light passing through the light guide member (18) is scattered. Here, since the light guide member (18) is disposed at a distance from the light exit surface of the LED (22) or the light guide member (18) provided adjacent thereto, the decoration for taxi in which the LED (22) is lit. When the lamp (10) is observed from the direction of the optical axis of the LED (22) (front and rear direction of the taxi when installed on the taxi roof), the LED (22) is provided on each of the light guide members (18). Can be visually recognized. In other words, when the taxi decoration lamp (10) with the LED (22) turned on is viewed from the optical axis direction side, the arch-shaped light emitted from the LED (22) overlaps several times so that a light tunnel appears. become.

  In particular, as described in claim 2, when the “LED (22) is a bullet-type LED”, the bullet-type LED has high directivity (that is, the light irradiation angle is narrow, the optical axis Because it can irradiate more light in the direction), it is possible to see the tunnel of light emitted from the taxi lamp (10) even from a distance.

  In addition, by using the LED (22) as a light source, an inverter or the like is not necessary at the time of lighting, and the apparatus can be easily configured, and the power consumption is low and economical.

  The invention described in claim 3 is the taxi decoration lamp (10) according to claim 1 or 2, wherein “a blinking pattern or color tone of the LED (22) is mounted on the substrate (24) on which the LED (22) is mounted”. Incorporating such control means, for example, attaching a decorative lamp for taxi (10) to an existing taxi rooftop indicator light (12), Even if the lead wire (26) of the taxi decoration light (10) is connected to the lead wire of the indicator light (12), the lighting pattern and color tone of the taxi decoration light (10) are displayed on the taxi roof. It can be controlled independently from the lighting pattern of the lamp (12). For this reason, more highly designable light can be emitted from the decorative lamp for taxi (10).
