DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device for a motorcycle.

[0002]

2. Description of the Related Art Recently, in a motorcycle, a headlight is turned on even in the daytime to improve the visibility of a vehicle ahead (lighting in the daytime, see JP-A-60-93701).

[0003]

By the way, turning on the headlight even in the daytime consumes a large amount of electricity, which causes a problem that a large-capacity battery is required especially in a so-called electric vehicle using electric power as a driving source. Also, the color of the headlight is similar to that of daytime sunlight because it is white.However, in order to obtain better visibility, the light color of the lamp is different from that of sunlight. Color is desirable. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a lighting device for a motorcycle which can obtain good visibility and consumes less power.

[0004]

According to the present invention, in order to achieve the above object, a reflecting film and a phosphor are sequentially formed on the inner surface of a glass tube constituting a lighting device from the outside while leaving a part of the glass tube. The configuration was such that vapor deposition was performed in a C-shaped section.

[0005]

The driver of the vehicle facing the vehicle equipped with the lighting device according to the present invention will see the inside of the lighting device from the portion of the glass tube without the phosphor and the reflective film. The emitted light is irregularly reflected and has extremely high brightness. For this reason, sufficient recognition can be obtained.

[0006]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a front view of a so-called scooter type motorcycle equipped with a lighting device according to the present invention. In the drawing, reference numeral 1 denotes a leg shield cowl that covers a head pipe, a front fork, and the like, 2 denotes a handle cover that covers a central portion of a handle 3, 4 denotes a front wheel, and 5 denotes a front fender that covers the front wheel 4.

Lights 7, 8 according to the present invention are mounted on the upper part of the leg shield cowl 1 and the upper part of the headlight 6 of the handle cover 2, respectively. Lights 7, 8
Are basically the same, only the lighting device 7 attached to the leg shield cowl 1 will be described here, and the description of the lighting device will be omitted.

FIG. 2 is an exploded perspective view of the lighting device 7. As shown in the figure, a concave portion 10 extending in the horizontal direction is formed on the upper portion of the leg shield cowl 1, and mounting portions 11, 12 for mounting a lens 20, which will be described later, are mounted on both ends of the concave portion 10. The fluorescent lamp 13 is fixed to the recess 10 by fixing means (not shown). Reference numeral 14 denotes an anti-vibration rubber provided at the center of the concave portion 10, and reference numerals 15 and 15 denote anti-vibration rubbers fixed to both ends of the fluorescent lamp 13, respectively. It is difficult to transmit to the light 13. Also, 16
Is an electric cable extending from the fluorescent lamp 13, one end of which is connected to a power supply mounted on the vehicle body through a hole also received in the rec shield cowl 1. The drive source of this motorcycle is a type in which a motor is directly driven to rotate by a battery instead of an internal combustion engine, and a 48 V battery is used as a power source.

As shown in FIG. 3A, a reflection film 18 and a phosphor 19 are sequentially formed on the inner surface of the glass tube 17 outside the fluorescent lamp 13 from the inner surface side of the discharge tube, as shown in FIG. Is deposited in a C-shaped cross section. The fluorescent lamp 13 is attached so that the undeposited portion 17a of the glass 17 that can see through the inside of the fluorescent lamp 13 faces the front of the vehicle body.
For example, a metal such as aluminum is used for the reflective film 18, and various fluorescent materials are used for the fluorescent material in addition to the calcium phosphate fluorescent material. Further, filaments (not shown) are attached to both ends of the fluorescent lamp 13.

FIG. 6 shows a cross-sectional structure of an ordinary fluorescent lamp. This conventional fluorescent lamp as the only was merely deposited phosphor 19 to the inner surface of the glass tube 17, undeposited portion of the reflective film and the glass tube is not provided.

In the lamp having the above-described structure, the inside of the lamp 17 has a very high brightness due to irregular reflection of the light emitted from the phosphor 19, and this light is applied to the undeposited portion 17a of the glass tube. Emitted from forward. Therefore, sufficient recognizability from the driver of the oncoming vehicle is secured. Also,
Since the above-described lighting device uses a fluorescent lamp as a light emitting source, the lighting efficiency is higher and the current consumption is smaller than that of a normal incandescent lamp.

In this embodiment, the lighting devices 7 and 8 using fluorescent lamps are connected to the handle cover 2 and the leg seal 1 in two.
Although it is provided at a location, the present invention is not limited to this, and it may be configured to provide only one of them.

FIG. 4 shows a second embodiment of the present invention. This embodiment is an example in which the present invention is applied to a motorcycle of a normal sports type, in which a lighting device 31 of the present invention is mounted on a front of a front cowl and above a headlight 30, and on a front of a rear-view mirror body 32. The lighting device 33 according to the present invention is also mounted. Light 3
1 has the same configuration as that shown in the first embodiment,
The description here is omitted.

As shown in FIG. 5, the lighting device 33 has a u-shaped fluorescent lamp 35 mounted in a concave portion 34 formed on the front surface of the rearview mirror body 32, and a lens 36 is covered from the outside. As described in the above embodiment, the reflection film and the phosphor are deposited on the inner surface of the glass tube 17 in the C-shaped cross section of the fluorescent lamp 35 except for a part.

In this embodiment, the same effect as that of the above-described embodiment can be obtained in that a part of the vehicle can be efficiently illuminated with a small amount of electricity consumption, and as shown in FIG. To any shape. In the above embodiment, the lamp of the present invention has been described by taking a fluorescent lamp as an example. However, the present invention is not limited to this, and the present invention can be applied to a lamp using a cold cathode tube.

[0016]

As described above, according to the present invention, the following excellent effects can be obtained. (1) The inside of the lamp has a very high brightness due to the diffused reflection of the emitted light, and the light is emitted to the outside through the undeposited part of the glass tube, so that the oncoming vehicle's recognizability is extremely excellent. Become. (2) By using a fluorescent lamp, the shape of the glass tube can be set arbitrarily, and the shape can be easily adjusted to the curved surface of the cowl. (3) Since the color of the fluorescent lamp can be easily changed by changing the color of the phosphor on the inner surface, it is possible to make the color most advantageous in viewability. (4) Since it is easy to apply a color to the outer periphery of the fluorescent lamp, it is possible to use an arbitrary color according to the vehicle body color, and the design is not spoiled. (5) Light emission efficiency is higher and current consumption is smaller than when a normal light bulb is used, so that a burden on a battery or the like is small. (6) Since the diameter of the glass tube is small and the reflection film is built-in, a compact arrangement is possible without taking the depth and height unlike other lighting devices. (7) Since it generates little heat, it can be built in a narrow part such as a rearview mirror or a resin member. (8) Since the light is emitted from the surface, uneven light emission does not occur unlike a lamp using a bulb, which is advantageous in design, and the brightness is uniform, so that there is no visibility directionality.
