BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicular lamp such as a map lamp or a console lamp which emits spot light, and can emit particularly long and narrow spot light. The present invention relates to a vehicle lighting device capable of preventing the generation of glare light.

[0002]

2. Description of the Related Art A conventional vehicle lamp of this type is generally
A lamp chamber is defined by a housing and a cover, a light source bulb is arranged in the lamp chamber, a circular through hole is opened in the cover, and a convex lens is provided in the circular through hole of the cover. When the light source bulb is turned on, the light from the light source bulb is emitted from the convex lens to the outside of the lamp chamber as a circular spot light in a predetermined direction to illuminate a predetermined place.

[0003]

However, the above-described conventional vehicle lighting device has a problem in that only a circular spot light can be obtained because the cover is simply provided with a convex lens.

An object of the present invention is to provide a vehicular lamp capable of obtaining a long and narrow spot light and preventing the generation of glare light.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a slit defining a cover defining a lamp chamber, while a lens is provided with light from a light source bulb as an elongated spot light outside the lamp chamber. Providing a convex portion for irradiating in a predetermined direction, inserting the convex portion of the lens into the slit of the cover, and providing a light diffusing element on the outer surface of the convex portion of the lens and the inner surface of the slit of the cover. Characterize.

[0006]

According to the present invention, with the above construction, the light from the light source bulb can be emitted as a long and narrow spot light through the convex portion of the lens inserted into the slit of the cover. Moreover, the light diffusing elements are provided on the outer surface of the convex portion of the lens and the inner surface of the slit of the cover even though the glare light may be conspicuous due to the elongated spot light. When reaching the outer surface of the section and the inner surface of the slit of the cover, the light is diffused by the light diffusing element. Therefore, the glare light is inconspicuous, and there is no fear that it will be given to the driver or the passenger as glare light.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vehicular lamp according to the present invention will be described below with reference to the accompanying drawings. This example describes an interior light equipped with a map lamp and a console lamp. In the figure, 1 is a housing. The housing 1 includes a horizontal portion 10, a recess 11 for a console lamp provided in the horizontal portion 10, and an opening 12 formed on one surface of the recess 11. In the figure, 2 is a cover. A quadrangular pyramid-shaped recess 20 for illuminating the spot light of the console lamp is provided in the center of the cover 2, and a small rectangular slit 21 is provided at the bottom of the recess 20, and a crimping pin is provided at the edge of the slit 21. 22 is integrally projected inside. A switch 23 for a console lamp is arranged adjacent to the recess 20 of the cover 2. A standing wall 24 is formed on the back surface of the cover 2 and is formed in the recess 1 of the housing 1.
One of the openings 12 is integrally projected. The cover 2 is mounted on the housing 1, and the standing wall 24 of the cover 2 is fixed to the opening 12 of the recess 11 of the housing 1. As a result, the lamp chamber 4 is defined by the housing 1 and the cover 2. In addition, 25 is a lens for a map lamp provided on the left and right ends of the cover 2,
Reference numeral 26 is also a switch for map lamps provided on both left and right ends of the cover 2. In the figure, 3 is a lens. The lens 3 has a partially cylindrical surface shape. Small through holes 30 are provided at both ends of the lens 3 and the lens 3
At the center of the front surface (convex side) of the collar, a flange-shaped convex portion 31
Through the slit 21 of the cover 2,
It projects integrally in a small rectangle. The convex portion 31 of the lens 3 is inserted into the slit 21 of the cover 2, the step portion 32 of the lens 3 is set to the edge of the slit 21 of the cover 2, and the cover 2 is inserted into the small through hole 30 of the lens 3. Insert the pin 22 of the
Is fixed to the cover 2. In the figure, 5 is a socket provided inside the recess 11 of the housing 1. By holding the light source bulb 50 for the console lamp in the socket 5 in a detachable manner, the light source bulb 50
Is disposed in the lamp chamber 4, and the convex portion 3 of the lens 3 is
1 will be opposed. In the figure, reference numeral 6 denotes the interior ceiling of an automobile equipped with the vehicle lamp (interior light) of the present invention. The vehicle lamp (indoor lamp) of the present invention includes the cover 2
The interior surface of the slit 21 and the longitudinal surface of the outer surface of the convex portion 31 of the lens 3 are installed in the room so as to face the driver or passenger side.

Thus, the light diffusing element 7 is provided on the entire inner surface of the slit 21 of the cover 2 and the entire outer surface of the convex portion 31 of the lens 3 by, for example, honing. Since the vehicular lamp of the present invention in this embodiment has the above-mentioned configuration, when the light source bulb 50 is turned on by operating the switch 23, the light from the light source bulb 50 passes through the convex portion 31 of the lens 3 and the lamp chamber. 4 is emitted in a predetermined direction as an elongated spot light to illuminate a predetermined place. In addition, the light diffusing element 7 is provided on the outer side surface of the convex portion 31 of the lens 3 and the inner side surface of the slit 21 of the cover 2 although the glare light may be conspicuous due to the elongated spot light. When the light from the bulb 50 reaches the outer surface of the convex portion 31 of the lens 3 and the inner surface of the slit 21 of the cover 2, the light is diffused by the light diffusing element 7, so that the glare light becomes inconspicuous and the driver or There is no possibility of giving glare to the passenger.

In the above embodiment, the interior lamp equipped with the map lamp and the console lamp has been described, but the present invention can be applied to other vehicle lamps. Further, in the above-described embodiment, the light diffusing element 7 is provided on the entire inner surface of the slit 21 of the cover 2 and the entire outer surface of the convex portion 31 of the lens 3.
The slits 21 may be provided on the inner surface of the slit 21 in the longitudinal direction and on the outer surface of the convex portion 31 of the lens 3 in the longitudinal direction.

[0010]

As is apparent from the above, the vehicular lamp of the present invention is provided with a slit in the cover that defines the lamp chamber, while the light from the light source bulb is provided in the lens as a narrow spot light outside the lamp chamber. Provided with a convex portion for irradiating in the direction, since the convex portion of the lens is inserted into the slit of the cover, through the convex portion of the lens inserted into the slit of the cover, the light from the light source bulb as an elongated spot light Can be irradiated. Moreover, the vehicular lamp of the present invention is provided with the light diffusing element on the outer surface of the convex portion of the lens and the inner surface of the slit of the cover, though the glare light may be conspicuous due to the elongated spot light. When the light from the bulb reaches the outer surface of the convex portion of the lens and the inner surface of the slit of the cover, the light is diffused by the light diffusing element. Therefore, the glare light is inconspicuous, and there is no fear that it will be given to the driver or the passenger as glare light.
