Description

[Detailed Description of the Invention] Industrial Field of Application The present invention relates to a vehicle lamp installed in an automobile, etc., and particularly to one in which the light source is an LED light emitting element.

<Conventional technology> Conventionally, a vehicle lamp using this type of LED light emitting element as a light source has an LED light emitting element 11 as shown in FIG.
is arranged on a printed circuit board 12, and this board 1
The lens 14 is fixed to the housing 13 of the vehicle lamp by heat caulking or the like, and since the LED light emitting element 11 is expected to have a semi-permanent life in practical use, the housing 13 is equipped with the lens 14. is attached by adhesive or other means to improve water resistance, and a lead wire 15 for feeding power to the LED light emitting element 11 is also introduced into the housing 13 via a grommet 16. With this structure, the LED The light emitting element 11 (including the substrate 12) is sealed and cannot be replaced.

〓Problem that the invention aims to solve〓 However, unlike other lighting equipment, vehicle lighting equipment has a much higher possibility of being damaged due to collisions with other vehicles, etc. In such cases, it is natural that they require repair. However, since the amount of light emitted by each LED light emitting element 11 is small, a plurality of LED light emitting elements 11 are used as a light source for this type of vehicle lamp, and compared to those using a conventional light bulb as a light source. In general, the light source becomes expensive, and when the lens 14 etc. is damaged due to the above-mentioned accident, the LED
Conventional LED that replaces everything including light emitting element 11
The structure of vehicle lighting equipment causes the problem of forcing the vehicle user to bear more costs than necessary, and at the same time, the same problem occurs in the unlikely event that the LED light emitting element 11 does not light up. It was something that caused

〓Means for Solving the Problems〓 The present invention is a specific means for solving the above-mentioned conventional problems. The light source section is removably attached to an insertion hole provided in the housing of the vehicle lamp via a one-touch holder that engages with a bayonet structure, and a lens is attached to the housing. The present invention solves the above-mentioned conventional problems by providing an LED vehicle lamp characterized in that the LED light emitting element is fixed and has a structure in which the LED light emitting element is replaceable.

〓Example〓 Next, the present invention will be explained in detail based on an example shown in the drawings.

What is indicated by the reference numeral 1 in FIG. 1 is an LED light emitting element, and a plurality of these LED light emitting elements 1 are arranged on a printed circuit board 2 and wired to form a light source part 3. An appropriate number of notches 2a are provided to allow engagement with the one-touch holder 4.

The one-touch holder 4 is formed of a material such as resin and has a generally cylindrical tube portion 4a and a lid portion 4b protruding from the bottom. A hook 4 that engages with the portion 2a
c and a locking claw 4d similar to the bayonet type used for exchanging camera lenses, and the lid 4b is provided with a ring-shaped locking claw 4d made of a highly elastic material such as rubber. Patsukin 5
is installed.

On the other hand, the bottom of the housing 6 of this LED vehicle light has a mounting hole 6a into which the cylindrical portion 4a can be inserted.
A slot 6b is provided on the periphery of the insertion hole 6a and fits in shape and position with the locking claw 4d, and a protruding stopper 6 is also provided on the periphery of the insertion hole 6a.
c is provided.

By doing this, in the LED vehicle lamp of the present invention, the light source section 3 consisting of the LED light emitting element 1 and the substrate 2 is first attached to the one-touch holder 4 using the cutout section 2a and the hook 4c, and then the housing 6 The housing 6 and the one-touch holder 4 are engaged by inserting the cylindrical portion 4a into the insertion hole 6a and rotating until the engagement claw 4d comes into contact with the stopper 6c.
Now that the LED light emitting element 1 has been attached to the LED vehicle lamp, it can be removed by reversing the procedure described above, thereby making it easy to attach and detach.

What is shown in FIGS. 2 and 3 is an example of a means for arranging a lead wire for supplying power to the LED light emitting element 1 on the lid portion 4b of the one-touch holder 4. As shown in FIG. 3, a hole may be provided in the lid portion 4b and a grommet 7 may be used to improve waterproofness. Alternatively, as shown in FIG. 3, a female socket may be formed by the connector terminal 8 and the frame portion 41b, and a male socket 9 may be used to make the electrical connection, and the means for doing so may be freely selected.

The lens 10 is attached to the housing 6 as described in the conventional example, but since this is not the gist of the present invention, a detailed explanation will be omitted here.

〓Effects of the invention〓 As explained above, according to the present invention, the LED light emitting element is arranged on a printed circuit board to serve as a light source, and the light source has a bayonet structure in an insertion hole provided in a housing of a vehicle lamp. Since the light source is attached to a one-touch holder that is attached to the lens, the light source can be attached and detached, allowing the relatively expensive light source to be reused even if the lens or other parts are damaged due to an accident. This has the excellent effect of not placing an unnecessary economic burden on the vehicle user, and also enables the light source section to be shared and standardized on the lighting equipment manufacturer's side, which is effective in streamlining production. becomes.
