Description

[Detailed description of the invention] [Industrial application field] This invention relates to an indoor lighting lamp, and more specifically, an indoor lighting device in which the lighting of the lamp can be controlled by operating the lamp cover in conjunction with an external switch. It is about lights.

[Prior Art] Indoor lamps in vehicles, etc. are lighted in conjunction with the opening and closing of a door or by the operation of a switch, and the direction of the light beam can be fixed or varied to make it convenient for viewing a map from the driver's or passenger's seat. A spot lamp is installed.

As described in Japanese Utility Model Publication No. 59-268, interior lighting lights with these configurations are equipped with a lever or push-type switch for blinking the lamps, and depending on the position of this switch knob, the lights are turned off at all times regardless of whether the door is opened or closed. You can select from three modes: blinking or always on regardless of whether the door is opened or closed.

[Problems that the invention aims to solve] However, in the conventional example mentioned above, the switching switch for blinking the lighting light is separately provided, which increases the number of parts and requires space for installing the switch, which also increases the cost and space. It also had the disadvantage of being disadvantageous.

This invention reduces the number of parts and costs by providing a moderation part for switching between three modes on the lens and making a see-saw movement, which doubles as a switch knob, and also by providing a switching contact point integrated with the bulb holder to provide a switch function. The purpose is to make it possible.

[Means for Solving the Problems] The purpose of this invention described above is to attach the lamp cover attached to the outer case so that it can see-saw with respect to the outer case, and to prevent one end of the lamp cover from slightly entering the outer case. It's tilted to the left,
This can be achieved by enabling three modes, OFF, DOOR, and ON, to be performed with the lamp cover held horizontally and tilted to the right.

[Function] In the indoor lighting lamp of this invention, by inserting one lengthwise end of the lamp cover, which is attached so as to be able to seesaw with respect to the outer case, into the outer case, one end can be used as a door switch of the outer case. The first fixed contact piece connected in series is in contact with the first movable contact piece of the lamp cover, and at the other end, the third fixed contact piece of the outer case and the second movable contact piece of the lamp cover are disconnected. When the lamp cover is turned off and the lamp cover is placed horizontally, the relationship between the first fixed contact piece and the first movable contact piece does not change, and the relationship between the third fixed contact piece and the second movable contact piece on the other end side remains the same. When the door opens and closes, the lamp flashes.When the other end is inserted into the outer case, the second fixed contact piece and the first movable contact piece come into contact with each other on one end side, and the second fixed contact piece and the first movable contact piece touch on the other end side. Since the fixed contact piece No. 3 and the second movable contact piece are in contact with each other, the switch is in the on state.

As shown in a and b, a wiring 5 is also attached to this set screw.

The lamp cover 2 is shown in Figure 1b, Figure 2 and Figure 4.
As shown in Figures a and b, there is a rectangular box-like body large enough to be inserted into the first recess 11 of the outer case 1 with a gap corresponding to the height of the uneven plate and spacer protrusion, which will be described later. Lens portions 22 are formed near both longitudinal ends of the top plate 21, and the chevron-shaped longitudinal side plates 23 have a fulcrum 24 at the center and the above-mentioned protrusion between the fulcrum 24 and the ends. 16
Spacer protrusions 26 are protruded from both sides of the plate so that they are diagonally symmetrical and have the same height as the uneven plate 25 and the convex portion of the uneven plate 25 to obtain a snap action. .

In this lamp cover 2, as shown in FIGS. 1a and 2, a lamp socket portion 411 is attached to one side of the mounting piece 412 in a mounting groove 231 formed in the side plate 23, as shown in FIG. 4b. Twin contacts 413 on the side
