A half mirror 15 is disposed in the head lamp opening 8b so as to cover the opening 8b, and the half mirror 15 is engaged and supported by an engagement recess 3c formed in the rear vertical wall 3b of the housing 3. ing. The half mirror 15 has a function of transmitting light from the headlamp bulb 12 and reflecting external light incident through the lens 4. For example, chromium or aluminum is provided on one main surface of the resin sheet. And a semi-transparent mirror in which the deposited layer is covered with a protective film.
[0019]
A reflecting plate (mirror) 16 is disposed in the head lens chamber B. The reflecting plate 16 is disposed so as to be inclined so as to reflect the light from the headlamp unit 6 that has passed through the half mirror 15 and to irradiate the light through the lens 4 to the outside. The lens chambers A and B are engaged and supported at the edge of the partition wall 8c.
[0020]
A turn lamp chamber A1 is formed on the back side of the reflector 16 in the head lens chamber B. The turn lamp chamber A1 is surrounded by the reflector 16, the rear vertical wall 3b of the housing 3, and the partition wall 8c of the extension 8, and is formed independently below the turn lens chamber A.
[0021]
A turn lamp opening 8d that connects the turn lens chamber A and the turn lamp chamber A1 is formed at the rear of the partition wall 8c, and the turn lamp unit 7 faces the head lamp opening 8d in the turn lamp chamber A1. Is arranged.
[0022]
The turn lamp unit 7 is configured such that a socket 19 is fixed to a bottom portion 18a of a substantially bowl-shaped multi-reflector 18 in which a plurality of reflecting surfaces for light distribution are compositely formed, and the turn lamp bulb 20 is detachable from the socket 19. Installed and configured.
[0023]
A half mirror 21 having the same function as the half mirror 15 is disposed in the turn lamp opening 8d so as to cover the opening 8d, and the half mirror 21 is formed on the rear vertical wall 3b of the housing 3. The engagement recess 3d is engaged and supported. Reference numeral 3e denotes a valve mounting hole.
[0024]
A reflective plate 22 is disposed in the turn lens chamber A. The reflection plate 22 is disposed so as to be inclined so as to reflect the light from the turn lamp unit 7 that has passed through the half mirror 21 and to radiate the light through the lens 4 to the outside. 8e is engaged and supported.
[0025]
Next, the effect of this embodiment is demonstrated.
According to the headlamp device 1 of the present embodiment, the inside of the housing 3 is divided into the turn lens chamber A and the head lens chamber B by the extension 8, and the head lens chamber B and the headlamp chamber B1 are separated by the bottom wall 8a of the extension 8. In addition, a lamp opening 8b is formed at the rear of the bottom wall 8a, and a headlamp unit 6 is disposed in the headlamp chamber B1 so as to face the lamp opening 8b. Since it is covered with the mirror 15, when the headlamp device 1 is viewed from the outside of the vehicle, it looks like a lamp, and the headlamp chamber 6 has a depth, but the headlamp unit 6 cannot be seen through the lens 4. Appearance. As a result, it is possible to produce a completely new and mysterious appearance in terms of design, and to stimulate demand.
[0026]
In the present embodiment, a reflecting plate 16 is disposed in the head lens chamber B, and light from the head lamp unit 6 (see a mark a in FIG. 1) transmitted through the half mirror 15 by the reflecting plate 16. Since the light is transmitted through the lens 4 to the outside, the front of the vehicle is irradiated when the lamp unit 6 is turned on, and the function as a headlamp can be exhibited.
[0027]
In the present embodiment, the reflector 16 forms a turn lamp chamber A1 at the rear of the head lens chamber B independently of the turn lens chamber A, and the turn lamp unit 7 is disposed in the turn lamp chamber A1, Since the half mirror 21 is disposed in the lamp opening 8d of the partition wall 8c, it has an appearance that the turn lamp unit 7 cannot be seen through the lens 4 and can produce a mysterious appearance as described above. Further, since the light from the turn lamp unit 7 is transmitted through the lens 4 by the reflecting plate 22 and is irradiated to the outside, the function as a turn lamp can be exhibited.
[0028]
In the present embodiment, the headlamp chamber B1 in which the headlamp unit 6 is disposed is provided below the head lens chamber B, and the turnlamp chamber A1 in which the turnlamp unit 7 is disposed below the turn lens chamber A is provided. Since it is provided, the longitudinal dimension of the entire apparatus can be reduced while ensuring the depth of each of the lens chambers A and B, and a compact configuration can be achieved.
[0029]
Furthermore, since the turn lamp chamber A1 is provided by effectively utilizing the space behind the head lens chamber B formed by the reflecting plate 16, the entire apparatus can be made compact in this respect as well.
[0030]
In the above embodiment, the case where the turn lamp chamber A1 and the head lamp chamber B1 are respectively provided below the turn lens chamber A and the head lens chamber B has been described. However, in the lamp device of the present invention, the lamp chamber is the lens chamber. May be provided on the side of the lens chamber.
[0032]
Furthermore, the lamp device of the present invention is not limited to a headlamp but can be applied to a rear lamp.
