[Detailed description of the device] [Industrial applications]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle lamp, and more particularly to a license lamp for illuminating a license plate.

[Prior art]

FIGS. 3 and 4 show examples of the structure of the conventional license lamp 90. The license lamp 90 is usually arranged in the vicinity of the license plate 10, and the light distribution characteristic is shown. If no measures are taken for the above, as shown in FIG. 5, an extreme illuminance difference is generated on the surface of the license plate 10 and the readability is impaired. A hood 92 that shields the reaching light is provided to obtain a light distribution characteristic in which the illuminance on the surface of the license plate 10 is made uniform. In addition, since the irradiation direction of the license lamp 90 is the same as the attaching / detaching direction of the light bulb 91, in preparation for disconnection of the light bulb 91, the license lamp 90 is attached / detached by screwing the hood 92 and the lens 93 together. It is supposed to be fixed by a free structure, and when replacing the light bulb 91, both the hood 92 and the lens 93 are removed.

However, it is very complicated to require removal of both the hood 92 and the lens 93 when replacing the light bulb 91, and, for example, the hood 92 is easily lost,
When this loss occurs, the above-mentioned light distribution characteristics cannot be obtained at all, and there arises a problem that the function itself of the license lamp 90 is lost, and a solution to this point is a problem. It was.

[Means for Solving the Problems]

The present invention, as a specific means for solving the above-mentioned conventional problems, shields a part of the irradiation light for irradiating the license plate with a uniform illuminance, in which the irradiation direction of the lamp and the attaching / detaching direction of the light bulb are substantially the same. In the license lamp in which the hood is disposed in the vicinity of the light bulb, the hood is pivotally supported at one end in a direction parallel to a direction orthogonal to the irradiation direction. By providing a license lamp, the above-mentioned conventional problems are solved.

【Example】

Next, the present invention will be described in detail based on an embodiment shown in the drawings. Reference numeral 1 in FIG. 1 denotes a license lamp according to the present invention (hereinafter abbreviated as lamp 1).
Is formed so that the irradiation direction and the attachment / detachment direction of the light bulb 2 are the same direction Z, and the hood 3 is arranged adjacent to the irradiation direction side of the light bulb 2, that is, in a state orthogonal to the direction Z, and further arranged in front. The license plate 10 is configured to irradiate the license plate 10 with a uniform illuminance in the same manner as the conventional example, but according to the present invention, as shown in FIG.
Is a highly elastic member such as a steel plate, and is the housing 5 of the lamp 1.
The upper contact piece 3a and the lower contact surface 5b are formed in a substantially U shape so as to have an upper contact piece 3a and a lower contact piece 3b, and the upper contact piece 3a and the lower contact piece 3b are formed. Shafts 3c, 3c are provided in a boss shape by, for example, press working at the end on the free end side with respect to, that is, the end on the side orthogonal to the direction Z, and at the same time the upper surface 5
a and the lower side surface 5b, or one of them, for example, the lower side surface 5b
When the hood 3 is fitted into the receiving hole 5c provided in the housing 4 and is rotatably supported by the housing 4 from a position orthogonal to the direction Z to a position parallel thereto, It is supposed to be retracted from the front surface of the light bulb 2. It should be noted that the above-described configuration for rotating is merely an example, and in actual implementation, the hood 3 is cantilevered and rotatable by using an appropriate engaging means such as an eyelet. It may be supported, and in order to securely fix the hood 3 in a predetermined position when the lamp 1 is used, a screw hole 3d or the like is provided as shown in FIG.
It is also possible to fix it to the housing 5 with. Next, the operation and effect of the lamp 1 having the above structure will be described. Since the hood 3 is rotatably supported by the housing 5 at one end, the lens 4 is detached when the bulb 2 is replaced. The hood 3 is retracted from the attachment / detachment direction of the light bulb 2 by being rotated after it is rotated, and the hood 3 can be replaced very easily, and the configuration is such that the hood 3 is rotated and retracted. Are not separated, and therefore there is no risk of losing the hood 3.

[Effect of device]

As described above, according to the present invention, the hood is rotatably attached to the housing so as to be retracted from the attachment / detachment direction of the light bulb, so that the hood also needs to be removed when replacing the light bulb as seen in the conventional example. Thus, it is possible to avoid the complexity and to make the handling easy, and at the same time, it is possible to solve the problems such as the loss of the hood at the time of the replacement, and it is possible to ensure the performance.
