Description

[Detailed Description of the Invention] [Purpose of the Invention] Industrial Application Field The present invention relates to an interior light for an automobile that is installed in the lower part of an instrument section to provide downward illumination.

BACKGROUND TECHNOLOGY Conventionally, lighting fixtures have been seen in which a lamp is installed in a cylindrical body and a reflector having a reflective surface is installed between the lamp and the body. Due to the extremely compact size and high density of equipment, it is extremely difficult for the operator to remove the lamp with his or her hands when replacing the lamp, and special tools are required for such removal work. However, maintenance is poor, especially for devices that are installed below the instrument section and illuminated downwards, forcing the user to crawl downwards and work in a cramped position when removing the device. This is the current situation, and it has the drawback of making the above-mentioned replacement work even more difficult.

Problems to be Solved by the Invention This invention enables lamp replacement of lighting equipment installed in the lower part of the instrument section to provide downward illumination, without making the working posture worse, and without requiring special tools when replacing the lamp. It is an object of the present invention to provide an interior light for automobiles that allows easy lamp replacement.

[Structure of the idea]

Means for Solving the Problems In view of the above, the present invention provides a cylindrical body having an intermediate wall and a female connector for attaching a lamp to the intermediate wall. In a lighting device in which a cylindrical reflector with a bottom is attached so as to be biased in the axial direction by a means and to be regulated within a predetermined operating range, a through hole having a diameter larger than the outside diameter of the lamp is protruded in the bottom of the reflector. For automobiles, a locking piece is provided at a position opposite to the bottom peripheral surface of the through hole to lock the outer peripheral surface of the lamp along with the reflector when the reflector is removed, thereby allowing the lamp to be removed. It is an attempt to overcome the above-mentioned drawbacks by providing an interior light.

Effects In this invention, when removing the lamp,
The reflector, which is biased in the axial direction by elastic means, is removed from the body, and as the reflector is removed, the cylindrical outer peripheral surface of the lamp is locked by the locking piece. This allows the lamp to be removed from the female connector at the same time.

Embodiment An embodiment of the present invention will be described below based on the drawings. Reference numeral 1 is an interior light for an automobile that is attached to the lower part of the instrument section 2 of the automobile to provide spot illumination of any location such as the center console or footwells.

Numerals 32 and 32a are engagement pieces that lock the cylindrical outer circumferential surface of the lamp 11, and project inward protrusions 33 and 33a at the tip at opposing positions on the circumferential surface of the bottom 27 of the through hole 26. It is provided so as to protrude in the axial direction of the cylindrical portion 28.

Reference numeral 34 denotes a cylindrical portion 2 on the surface of the bottom portion 27, which is the relevant position for pressing the operating rod 15 of the switch 14.
This is a pressing portion that protrudes in the axial direction of 8.

35, 35a are engagement protrusions disposed at positions relative to the protrusions 22, 22a of the engagement parts 17, 17a;
Protrusions 37, 3 having a triangular cross section are provided to protrude in the axial direction of the cylindrical portion 28 by a predetermined length from the surface of the cylindrical portion 28.
7a is provided to protrude outward.

In addition, the engaging parts 17, 17a and the engaging protrusions 35, 35
The attachment/detachment structure of a is not limited to the above-mentioned structure, and in short, any structure may be used as long as it allows the reflector 4 to be freely attached to and detached from the body 3, and also restricts the operating range in the axial direction when attached. For example, although not shown, a commonly used J-throttle groove may be provided in the body 3, and a protrusion that is guided and engaged with the J-throttle groove may be provided in the reflector 4 to provide an attachment/detachment structure.

In the figure, 38 is a positioning recess, and 39 and 39a are fitting protrusions for the condenser lens 5.

The condenser lens 5 is attached to the condenser lens unit 30 of the reflector 4 to cover the opening 29 and form a lens 40 that condenses light in a predetermined direction.

In addition, 41 is a positioning protrusion, and 42 is the above-mentioned fitting protrusion 3.

[Effect of idea]

In short, the present invention has a cylindrical body 3 which has an intermediate wall 7 and a female connector 10 for attaching a lamp 11 to the intermediate wall 7. In a lighting device, a cylindrical reflector 4 with a bottom is attached so that the lamp 1 is energized and regulated within a predetermined operating range.
A through hole 26 having a diameter larger than the outer diameter of 1 is bored,
At opposing positions on the circumferential surface of the bottom 27 of the through hole 26 are locking pieces 32, 32a that lock the outer surface of the lamp 11 with the reflector 4 when the reflector 4 is removed, thereby allowing the lamp 11 to be removed. Since the lamp 11 is provided in a protruding manner, when the lamp 11 is removed, the reflector 4, which is biased in the axial direction by the elastic means, is moved from the body 3.
As the reflector 4 is removed, the lamp 11 is simultaneously removed from the female connector 10 with the cylindrical outer peripheral surface of the lamp 11 being locked by the locking pieces 32, 32a. Because it can be removed, the lamp is particularly suitable for lighting equipment that is installed in the lower part of the instrument section 2 in the vehicle interior, in other words, in the place where the footwells, map, etc. on the center console are placed. 11, the lamp 11 can be easily removed together with the reflector 4, even if the attachment point is very difficult to see, if the operator can reach it, and the lamp 11 can be easily removed together with the reflector 4. Compared to having to remove the lamp using a special tool while checking the installation location by the worker himself, this improves the work efficiency of lamp replacement without worsening the working posture and eliminating the need for a special tool. Its practical effects are enormous.
