DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention aims to provide a new vehicle marker light for reducing the number of parts and the number of assembly steps.

[0002]

2. Description of the Related Art A vehicular marker lamp is known which is disposed inside a rear window of a vehicle for the purpose of improving visibility of an intention to stop a following vehicle.

For example, Japanese Patent Application Laid-Open No. Sho 64-109142 discloses that a lamp disposed in a synthetic resin lamp body having an open front has upper, lower, and rear portions covered with a reflector. A lamp is disclosed which is supported by a protrusion protruding from a rear wall and has a configuration in which other parts than the support part are separated from the inner surface of the lamp body.

[0004] In a vehicle sign light a shown in FIG. 21, a lamp body b made of synthetic resin comprises a main part b1 and a hood part b2 detachably attached to a front part of the main part b1. Are connected by screws c and c.

A lens d made of a transparent synthetic resin is fitted inside the lamp body b near the front end of the hood b2 by bonding, welding, or the like.
It is fixed to.

A metal reflecting mirror f is disposed in a lamp chamber e defined by the lamp body b and the lens d. The reflecting mirror f has a mounting screw g partially inserted therethrough. The lamp body b is supported by the main part b1 by being screwed into a protrusion h formed on the main part b1.

[0007] i is a cylindrical lamp socket,
The lamp socket i is wound around a metal band j, and the mounting screws k, k are inserted through the insertion hole at the end of the metal band j and the insertion hole of the reflecting mirror f corresponding thereto, respectively. The bosses l, l formed in b are held by the bosses l, l by screwing into the pilot holes m, m.

Reference numeral n denotes a light bulb whose base o is detachably attached to a lamp socket i.

P is a rear window glass.

[0010]

In the above-described vehicle marker lamp a, the main part b1 and the hood part b2 of the lamp body b are connected by screws c and c. Since the reflecting mirror f is a separate member from the lamp body b and is attached to the main part b1 using the metal band j and the attaching screws k, k, the number of parts is large, and assembly is time-consuming. There's a problem.

[0011]

According to the present invention, there is provided a vehicle marker lamp comprising:
In order to solve the above-mentioned problem, a lamp body is formed from an upper body and a lower body which are vertically divided, and a hood surrounding a lens is integrally formed with the upper body or the lower body, and a reflection body is formed. The mirror is formed integrally with the upper body or the upper and lower bodies, and the light source bulb is mounted in a mounting hole of the reflecting mirror.

[0012]

Therefore, according to the present invention, since the hood portion is formed integrally with the upper body or the lower body and the reflecting mirror is formed integrally with the upper body or the lower body, the number of parts is reduced. The steps of attaching the hood to the main part of the lamp body and attaching the reflector to the lamp body can be reduced.

Mounting holes 28a, 29a and mounting hole 1 in upper body 2b
After being respectively inserted into the brackets 5 and 15, they are separately screwed into the screw holes 6 a and 6 a of the bosses 6 and 6 in the lower body 2 a, and are attached to the bracket 25.

In the high-mount stop lamp 1, the hood 3 is formed integrally with the lower body 2a of the lamp body 2, and the reflector 13 is formed integrally with the upper body 2b. As a result, the number of components is small and assembly is easy.

That is, when assembling the high-mount stop lamp 1 and attaching it to the vehicle body, first, the lens 20 is temporarily fixed to the hood portion 3 of the lamp body 2.
After attaching the bulb 18 to the reflector section 13, the upper body 2b is moved to the lower body 2a so as to cover the opening 5 of the lower body 2a.
And the upper body 2b and the boss portion 6 are fixed to the body mounting portion 26 of the bracket 25 by using screws 35, 35.
Together. Then, the vehicle body mounting portion 2 of the bracket 25
If you attach 7 to the predetermined position of the vehicle body with screws,
The work of mounting the high mount stop lamp 1 on the vehicle body is completed. In replacing the bulb 18, the bulb 18 is removed through the bulb insertion hole 16 formed in the upper body 2b, and then the new bulb 18 is inserted through the bulb insertion hole 16.
Is located in the lamp body 2 and the glass bulb 18a is simply inserted into the bulb mounting hole 14 from the back side of the reflector portion 13 and attached to the reflector portion 13, so that the work is easy.

In the above embodiment, the reflector 13 is formed integrally with the upper body 2b. However, as shown in FIG.
Of course, it may be formed integrally with a. Further, the hood portion 3 can be formed integrally with the upper body 2b.

[0047]

As is apparent from the above description, according to the first aspect of the present invention, the hood portion is formed integrally with the upper body or the lower body, and the reflecting mirror is formed on the upper body or the lower body. Since it is formed integrally with the first member, the number of parts and the number of assembling steps can be reduced.

According to the second aspect of the present invention, a heat radiating hole is formed in the upper body at a position above the light emitting portion of the light source bulb, and a metal made so as to cover the heat radiating hole from above. Since the bracket can be attached to the upper body and the lamp can be attached to the vehicle with this bracket, using the bracket as a heat sink and mounting member eliminates the need for a dedicated member for heat dissipation and reduces the number of parts. it can.

According to the third aspect of the present invention, an insertion hole for positioning the light source in the lamp body is formed in the upper body, and the light emitting portion of the light source is inserted into the mounting hole of the reflector through the insertion hole. By doing so, the replacement work of the light source can be easily performed.
