Abstract

PROBLEM TO BE SOLVED: To make attachment and detachment of a lamp easy and eliminate possibility of damaging a lamp cap, etc., by providing a lamp having lamp lead terminals, a luminaire main body having a lamp socket, and a lamp support fixture to hold a lamp. SOLUTION: A lamp support fixture 3 is to hold a lamp 1 at a position where lamp lead terminals 4 and socket lead terminals 7 are brought into contact and constituted of a pair of wrapping pieces 10 extended out of the tip ends of the lamp sockets 8 to wrap the outer circumferential face with a round cross-section of a cap 5. The wrapping pieces 10 are widened due to elasticity of resin by pushing a cap 5 of the lamp 1 between the wrapping pieces 10 of the supporting tool 3 and wrap the cap 5 of the lamp 1 and based on the elastic force, a recessed part 6 is fitted in a projected part 9 and at the same time terminals 4 are brought into contact with terminals 7 and electric communication can be carried out. The contacting state of the lamp 1 is retained by the supporting tool 3, so that electric communication is carried out and the contacting state of the lamp 1 is released by the supporting tool 3, so that the lamp 1 can be detached.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to FIG. That is, this lighting fixture has a lamp 1, a fixture main body 2, and a lamp support 3 made of resin. The lamp 1 has a contact conductive lamp terminal 4.
The lamp 1 according to the embodiment is a ring-shaped fluorescent lamp. And the exposed surface is flush with the bottom surface.

The fixture main body 2 has a resin lamp socket 8 provided with a socket conductive terminal 7 for contacting and supplying power to the lamp conductive terminal 4. Lamp socket 8 of embodiment
The base end 8a is attached to the instrument main body 2 and the tip end hangs down from the instrument main body 2, and the tip end is provided with a convex portion 9 fitted into the concave portion 6, and the socket conductive terminal 7 is embedded on the surface of the convex portion 9. The exposed surface is flush with the surface of the projection 9.

The lamp support 3 maintains the lamp 1 at a position where the lamp conductive terminal 4 and the socket conductive terminal 7 are in contact with each other. In the embodiment, the lamp support 3 extends from the tip of the lamp socket 8 and has a cross section of the base 5. It is formed by a pair of holding pieces 10 holding a circular outer peripheral surface. When the base 5 of the lamp 1 is pushed between the pair of holding pieces 10 of the lamp support 3, the holding piece 10 spreads due to resin elasticity and is held by the base 5 of the lamp 1, and the elasticity causes the recess 6 to be convex. The lamp conductive terminal 4 is brought into contact with the socket conductive terminal 7 while being fitted into the portion 9, so that power can be supplied.

The lamp 1 is held by the fixture body 2 by a lamp support spring or the like (not shown) in addition to the lamp support 3. According to this embodiment, power is supplied by contacting the lamp conductive terminal 4 of the lamp 1 with the socket conductive terminal 7 of the lamp socket 8 and maintaining the contacted lamp 1 with the lamp support 3. By releasing the maintenance of the lamp 1 with the lamp support 3, the lamp 1 can be attached and detached. Further, since the lamp pin is not used unlike the related art, the lamp pin is not damaged, and the lamp can be easily attached and detached without troublesome alignment between the pin and the hole.

Further, the fitting of the concave portion 9 and the convex portion 6 can prevent the lamp 1 from rotating in the annular circumferential direction and also prevent the lamp 1 from rotating in the circumferential direction in the cross section. FIG. 2 shows a second embodiment of the present invention. That is, in this lighting apparatus, in the first embodiment, the concave portion 6 of the base 5 of the ring-shaped lamp 1 is formed by a cutout concave portion obtained by cutting a cross section of the cylindrical base of the lamp 1 in the circumferential direction. 6
Is provided with a lamp conductive terminal 4. In opposition to this, the lamp socket 8 has a width dimension that fits into the concave portion 6, and a socket conductive terminal 7 is provided at the tip thereof. The lamp support 3 is provided adjacent to the lamp conductive terminal 4 of the recess 6 and the socket conductive terminal 7 of the lamp socket 8, respectively. And the magnet 12 serving as the main body.

When the lamp socket 8 is inserted into the concave portion 6 of the base 5 of the lamp 1, the magnets 11 and 12 are attracted to each other, and the lamp conductive terminal 4 and the socket conductive terminal 7 are brought into phase contact with each other, so that power can be supplied. The lamp socket 8 is attached to the fixture main body 2 by a lead wire 13, and is mounted in the concave portion 6 of the base 5 of the lamp 1. Further, the lamp 1 is held on the fixture body 2 by a lamp support spring or the like (not shown).

This embodiment has the same functions and effects as those of the first embodiment, and further, because it is attracted by the magnets 11 and 12,
The force for expanding the lamp support 3 is unnecessary, and the lamp support 3 can be easily mounted. 3 to 5 show a third embodiment of the present invention. That is, in this lighting apparatus, the lamp support 3 includes a magnet 12 provided on the lamp socket 8 and a steel piece 15 which is provided on the base 5 of the lamp 1 ′ and is a magnetic piece that is attracted to the magnet 12. Further, a side recess 16 is formed on the side surface of the recess 6, and a side protrusion 17 that fits into the side recess 16 is formed.
Fits into the side recess 16 and prevents the lamp 1 'from sliding in either the circumferential direction or the radial direction. The lamp 1 'is a ring-shaped fluorescent lamp. The lamp 1' comprises a substantially C-shaped inner arc tube 18 and an outer arc tube 19. A filament is provided at one end and a connecting portion for communication is provided at the other end. The part is covered with a base 5.

According to this embodiment, in addition to the effects of the second embodiment, the lamp conductive terminal 4 and the socket conductive terminal 7 are attracted by the attraction of the magnet 12 of the lamp socket 8 and the steel piece 15 of the lamp 1 '. Can be maintained, and since the steel piece 15 is provided on the lamp 1 ', the cost can be reduced as compared with the case where a magnet is provided. Also,
Since the steel piece 15 is provided on the lamp side, which is a consumable part, and the magnet 12 is provided on the lamp socket 8 side, it is more economical than the opposite case. In addition, since the side projection 17 is fitted into the side recess 16, it is possible to reliably prevent the lamp socket 8 and the base 5 from sliding in any direction.

In the present invention, any material other than the magnet can be used as long as it can maintain the contact state between the lamp conductive terminal 4 and the socket conductive terminal 7.

[0017]

According to the lighting apparatus of the first aspect, power is supplied by contacting the lamp conductive terminal of the lamp with the socket conductive terminal of the lamp socket, and maintaining the contacted lamp with the lamp support. The lamp can be detached by releasing the maintenance of the lamp with the lamp support. Further, since the lamp pin is not used unlike the related art, the lamp pin is not damaged, and the lamp can be easily attached and detached without troublesome alignment between the pin and the hole.

According to the lighting apparatus of the second aspect, in addition to the effect of the first aspect, the contact state between the lamp conductive terminal and the socket conductive terminal is maintained by the attraction between the magnet of the lamp socket and the magnetic piece of the lamp. can do. If the magnetic piece provided on the lamp is a steel piece, the cost can be reduced as compared with the case where a magnet is provided.
