Description

[Detailed description of the invention] ≪Technical field of the invention≫ The present invention is a preliminary wedge base bulb for vehicle lighting devices such as parking lamps, side marker lamps, and clearance lamps that use wedge base bulbs as light sources. The present invention relates to a vehicle lamp equipped with a holding device.

≪Prior art and its problems≫ The built-in bulbs of vehicle lights are prone to breakage due to vibrations while driving, especially vehicle lights such as parking lamps, side marker lamps, clearance lamps, etc. that use wedge base bulbs. If the wedge base valve is left disconnected, it may cause a serious accident while parking or driving. Therefore, in the event that a valve is disconnected, it is necessary to immediately replace the valve, so it is necessary to keep a spare wedge base valve in the vehicle. Traditionally, the wedge base valve was stored in the vehicle by storing it in the glove box or in a bag containing tools. With this method, there are problems that other objects may hit the wedge base bulb during storage, damaging or damaging the bulb, and that the bulb is stored away from the lamp when replacing it. There was a problem that not only did it take a lot of time to do the work, but they also forgot where they were stored and ended up wasting time unexpectedly. To solve these problems, today's vehicle lighting equipment such as parking lamps, side marker lamps, and clearance lamps are equipped with spare wedge base bulbs for use in the event that the wedge base bulb breaks. There are some lamps that have a storage area in the main body of the lamp to secure the storage area and simplify the replacement work.

A conventional vehicle lamp provided with a storage area for this spare wet base bulb has a structure as shown in FIG. 1, for example. To explain this structure in more detail, this vehicular lamp has a main light source bulb c and a wedge base bulb l disposed as light sources in a lamp chamber defined by a housing a, a front lens b, and a back cover k. Become. The front lens b is fixed to an outer lens d having a fisheye prism e formed on its inner surface, and an inner wall surface of a joint leg m formed at the periphery of the outer lens d, and is attached to a refractive prism g and its outer periphery. reflective prism h
and an inner lens f having a so-called direct-light Fresnel prism, and this lens b is formed of acrylic resin or polycarbonate resin, respectively. Further, the housing a is open at both ends, and a groove n is provided at the periphery of the opening at one end. An adhesive x such as hot melt is applied to the groove n, and then an adhesive x is applied to the outer lens d. The joint leg m is press-fitted into the groove n and bonded, and the front lens b is attached so as to close the opening at one end of the housing a. A positioning protrusion p protruding from the inner wall surface is provided on the inner wall surface near the other end opening of the housing a, and the peripheral joint wall r of the back cover k is applied to the protrusion p with respect to the other end opening. The back cover k is attached and fixed in the closed position. This back cover
is made of a resin material, and is provided with a socket s for attaching the wedge base bulb l on the inside of the lamp chamber, a bulb fixing seat part t for fixing the main light source bulb c via the bulb holder member w, and a rear side.

A spare wedge base valve l' is housed in the elastic locking pieces B, B while pushing and expanding the space between the elastic locking pieces B, B. The wedge base valve l' will be held thereafter by the locking claws A, A, and if you wish to remove the spare wedge base valve l', you will have to push apart the elastic locking pieces B, B. It is therefore easily removable, and this arrangement provides a retaining device for the reserve wedge base valve.

The conventional vehicle lamp configured in this manner is attached to the vehicle body E via the rubber packing material D, but elastic locking pieces B, B are provided on the back of the back cover k, and the elastic locking pieces B, B In the case of a vehicle lamp equipped with a holding device for storing a spare wedge base bulb l', the spare wedge base bulb l' is exposed outside the lamp, so the lamp cannot be attached to the vehicle body. When installing on E, or when loading and unloading luggage from the trunk compartment inside the vehicle body E,
Not only did it often occur that the vehicle body E or the cargo collided with each other and caused damage, but also,
A problem has arisen in that the spare wedge base valve l' may fall off from the holding device and be lost or damaged during transportation for assembly into the vehicle body E or while the vehicle is running.

≪Purpose of the invention≫ The present invention was developed in view of the problems with conventional vehicle lights. The wedge base valve will not be damaged due to collision, damaged due to falling off, or lost due to falling off, and furthermore, the spare wedge base valve will not be lost or damaged due to falling off while the vehicle is running.
