Description

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to automobile lamps such as headlamps, and more particularly to a method for forming a socket holder, which is a part for inserting a light bulb into the lamp. K. Prior Art Conventionally, when a design change is made, such as changing the type of light bulb, such as brightness, in order to improve performance, users have to take precautions to prevent them from accidentally inserting the old type. This was dealt with by changing the type of light bulb base, and by doing this, different types of light bulbs, including old type light bulbs, did not have to be inserted repeatedly. [Problems that invention K aims to solve] However, in recent years, the demands of users have become more sophisticated.
When design changes are made to improve performance as described above, improvements are often made to improve color rendering properties, not just to make them brighter, and specifically, new types of light bulbs such as halogen light bulbs are adopted. At the beginning of the change, it took some time for this new type of light bulb to reach the end repair market, such as gas stations, and for this reason, there were cases where core breakage occurred in the early stages. This caused major problems, such as difficulty in obtaining repair parts and, for example, the automobile itself becoming unusable.

[Means to solve the problem]

The present invention provides a method for forming a socket holder for an automobile lamp when a lamp base to be used is changed, such as a specification change, as a specific means for solving the conventional problems described above. It has a structure that is compatible with the base, and has a holding mechanism that adjusts the position of at least one filament relative to the reflector for the old type of light bulb base, so that both the new and old types of light bulbs can be used. The above-mentioned conventional problems are solved by providing a method for forming an automobile lamp socket holder characterized by the following. K Embodiment Next, the present invention will be described in detail based on an embodiment shown in the drawings. The ones shown in FIGS. 1(A) and 1(B) are general light bulbs 1, including those used before the design change was implemented, and are specifically defined in P15D-25 by JIS JJIm, A 25W main filament 13 is attached to a cap 11 having a flange 12 provided with a positioning part 12a, and a 25W main filament 13 is placed in a valve filled with gas at normal pressure (1 atmosphere or less).
This type of light bulb will be collectively referred to as the old type light bulb 1 below and will be described below. What is shown in Figure 2 (A) and (B) is the light bulb 2 used after the design change, which also conforms to JIS standard 515.
D-24, three positioning parts 22a, 22
It is equipped with a cap 21 having a flange 22 provided with b and 22c, and has a 35W main filament 23 and a 30W sub-filament 24 inside a valve filled with high-pressure gas (1 atm or more). This light bulb has increased brightness and better color rendering than the new type light bulb 1, and will be described below as a new type light bulb 2. 3(A), (B), and (C) show a socket holder 3 according to the present invention, which is basically a JIS standard 815D-24 which is inserted into the new type of light bulb 2.
It is formed in a shape that fits the cap 21 of the vehicle and is attached to the reflector of the automobile lamp, and the three positioning portions 22a, 22b, 22c provided on the cap 21 are
a notch 31a formed with a corresponding J slot, respectively;
31b and 31c, and the new type of light bulb 2 is inserted into the socket holder 3 by fitting the respective positions and rotating them slightly. At this time, the main filament 23 and the sub-filament 24 Needless to say, it is arranged at a predetermined position on the above-mentioned reflecting mirror. Furthermore, according to the present invention, projections 31d and 31e are provided on the inner surface of the socket holder 3 as holding portions by processing means such as pressing, so that it is possible to mount an old type light bulb 1. At the time of this installation, the positioning part 1 provided on the flange part 12 of the base 11 of the old type light bulb 1 is used.
2a corresponding to the notch 31a and inserted, the old type light bulb 1 has the positioning part 12a, the notch 31a1, the flange 12, and the projections 31d, 31.
It is attached to a predetermined plane defined by the three points e and At this time, the projection 31d according to the present invention. 31 (3 refers to the main filament 13 of the old type light bulb 1 by adjusting the position indicated by the reference numeral in the figure and tilting the above-mentioned predetermined plane appropriately).
Alternatively, the position of the sub-filament 14 with respect to the reflecting mirror may be adjusted to obtain light distribution characteristics that do not impede practical driving. FIG. 4 shows this adjustment. A socket holder 3 according to the present invention is attached to the reflecting mirror 4 by means such as caulking, and the old type light bulb 1 is attached to the socket holder 3. Installed as described.
Here, the point P is a reference point determined by the positioning portion 12a and the notch 31a, and the protrusion 31
By adjusting the position of d (or 31e), the old type light bulb 1 is installed with an upward tilt, for example, the position of the sub-filament 14 is appropriately positioned above the focal point F of the anti-tJJM 14. This is to avoid dazzling oncoming vehicles. The above explanation is just an example, and the point is to use a non-standard light bulb to obtain light distribution characteristics that do not hinder practical driving. Needless to say, it is more preferable if it can be applied to both filaments 13 and 14. By doing so, the automobile lamp to which the socket holder 3 of the present invention is attached can obtain orientation characteristics that allow it to run with at least two types of light bulbs, old and new. Note that this type of cap has various shapes other than those explained in the above embodiments, and the present invention is not limited to these embodiments, but can be modified by appropriate means for each shape. It goes without saying that this modification does not detract from the gist of the present invention.

【Effect of the invention】

As explained above, according to the present invention, the socket holder has a structure that is compatible with the new type of light bulb base, and has at least one filament for the old type of light bulb base.
By having a holding mechanism that adjusts the position relative to the reflector, it is possible to use a light bulb that was developed using new technology and is not widely available in the end repair market. This has the excellent effect of making it possible to run a car by installing an old type of light bulb that is easily available even when it is not available.
