Problems solved by technology

If this device is used in a 2-lamp structure, under the same front projected area, to obtain a brighter headlamp, there must be a high-voltage generating circuit for lighting the discharge lamp, and on the existing basis, each lamp needs to be added 1 circuit will inevitably lead to an increase in weight and cost

Embodiment Construction

[0041] Below, the embodiments of the present invention are described with reference to the drawings, and the drawings are directed by symbols.

[0042] figure 1 It is a perspective view of a two-wheeled motor vehicle with a headlight device of the present invention. The vehicle body of this two-wheeled motor vehicle 1 has front wheel 3 and rear wheel 4 in front and rear; The upper part is also provided with fuel tank 5 and vehicle seat 6 successively; 10.

[0043] figure 2 (a) and (b) are comparison diagrams of the conventional example and the first embodiment of the present invention.

[0044] (a) shows the conventional 1st comparative example. Since this figure is the same as that explained in FIG. 12, the symbols are used and the explanation is omitted. And the height (longitudinal dimension) of upper reflector 104 is determined as h1, the height (longitudinal dimension) of lower reflector 105 is determined as h2, and the total height of two reflectors 104,105 is dete...

Abstract

A head lamp device for motor driving bicycle has a structure in which a discharge lamp having a discharge bulb and a reflector of a substantially hemispheric shape is arranged in an upper part of a housing; a filament having a filament bulb and a reflector of a substantially hemispheric shape is arranged in a lower part of the housing; and the front opening of the lamp housing is covered by a front lens. The discharge bulb can generate two to three times as much luminous flux as a conventional filament bulb. As a result, it is possible to reduce the size of the discharge bulb, compared to the filament bulb. This makes it possible to reduce the overall size of the head lamp device.

Description

technical field [0001] The invention relates to a headlamp device for a motor vehicle Background technique [0002] A headlight device is arranged in the center of the front part of a motorcycle on two wheels. However, such headlight devices are mostly single-lamp type headlamps, or multi-lamp type headlamps in which two or more lamps are juxtaposed on one vehicle. For example, in the headlight of a motorcycle disclosed in Japanese Patent Publication No. 63-9498, as shown in FIG. 5 , a pair of left and right lamp devices 16, 16 are arranged in this publication. [0003] Fig. 12 is a cross-sectional view of a conventional up and down 2-lamp type headlamp. The structure of this headlamp is: inside the lampshade 101, filament bulbs 102, 103 are installed up and down, and these filament bulbs 102, 103 are respectively surrounded by slightly hemispherical reflectors 104, 105. The front opening of the shade 101 is closed by a front lens 106 . [0004] Filament light bulbs 102,...
