Problems solved by technology

[0006] In the lamp device described in Patent Document 1, although the number of light-emitting diodes when the lamp device is viewed from the front can be seen to be larger than the actual number by arranging a plurality of reflective surfaces, there is no special consideration for viewing the lamp from an oblique direction.

Embodiment Construction

[0067] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. figure 1 It is a side view of the motorcycle 1 provided with the lamp device 30 according to the first embodiment of the present invention and the lamp device 90 according to the second embodiment of the present invention. A pair of left and right front forks 3 that rotatably pivotally support a front wheel WF are attached to the front side of the vehicle body of the vehicle frame 2 , and are steerable by operating a handle 4 . A meter unit 6 and a headlight 7 are attached to the front of the vehicle body of the joystick 4 , and a lamp device 30 is installed at a position between them. The lamp device 30 functions as a signal lamp for recognizing the presence of the motorcycle 1 by other vehicle occupants or pedestrians using light emitted from a light source such as a light emitting diode. In addition, in this illustration, one lamp device 30 is prov...

Abstract

The present invention provides a vehicle lighting device which can keep the visibility of the light even at a state of seeing in an oblique direction with a preset angle relatively to the irradiation direction of the light device. The light device (30) comprises a substrate (32) which is formed with an array of 2 lines * 4 rows and is distributed with light sources (11-14, 21-24), and walls (31T), (31U), (31L) and (31R) which extend from the end surface of the substrate (32) to the irradiation direction of the light source and surrounds the substrate (32). The surfaces at the light source side of the wall part are reflecting surfaces (31TN), (31UN), (31LN) and (31RN). Supposing the light sources in a same line are configured with a same interval D1, and supposing the distances from the light sources at two ends of the line to the adjacent reflecting surface are respectively D2, the D2 is set to larger than (1 / 3)*D1 and less than (2 / 3)*D1. Supposing the light sources in a same row are configured with a same interval S1, and supposing the distances from the light sources at two ends of the row to the adjacent reflecting surface are respectively S2, the S2 is set to larger than (1 / 3)*S1 and is less than (2 / 3)*S1.

Description

technical field [0001] The present invention relates to a vehicle lamp device, and particularly to a vehicle lamp device capable of maintaining the visibility of the lamp even when viewed from an oblique direction having a predetermined angle with respect to the irradiation direction of the lamp device. Background technique [0002] Conventionally, with regard to lamp devices installed on motorcycles and other vehicles to emit light to occupants of other vehicles or pedestrians, various methods for improving the visibility and design of the lamps and achieving low manufacturing costs have been investigated. structure. [0003] Patent Document 1 discloses a vehicle lamp device in which a plurality of reflective surfaces are arranged around a light source mounting surface on which light emitting diodes as light sources are mounted, thereby reducing the number of light emitting diodes when viewed from the irradiation direction of the lamp device. Appears to be more than it act...
