Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a lighting fixture, and more particularly, to an improvement in a lamp support structure in the lighting fixture.
[0002]
[Prior art]
Conventionally, as a lighting fixture equipped with a compact fluorescent lamp, a socket is fixed sideways inside the lighting fixture body, a base of the compact fluorescent lamp is attached to the socket, and the compact fluorescent lamp is supported in the socket. For example, there is Japanese Patent Publication No. 62-17358.
In general, the socket has a rotating structure that allows easy attachment and detachment of compact fluorescent lamps.
[0003]
[Problems to be solved by the invention]
By the way, according to the lighting fixture having the conventional structure described above, it is easy to attach and detach the compact fluorescent lamp to / from the socket. However, the compact fluorescent lamp has a drawback that the light distribution changes due to its own weight and tilts with use.
In addition, if a lighting fixture is used indoors or outdoors with vibration, there is a risk that the compact fluorescent lamp will easily fall out of the socket. If the compact fluorescent lamp is securely screwed into the socket, the compact fluorescent lamp will not fall off because it is locked, but the compact fluorescent lamp may fall off if the screwing is not secure.
[0004]
The present invention has been invented in view of the above points, and has a relatively simple structure, and allows a compact fluorescent lamp to be easily attached to and detached from the socket. Further, the compact fluorescent lamp is securely supported by the socket, and light distribution is achieved. It aims at providing the lighting fixture which does not change.
[0005]
[Means for Solving the Problems]
The present invention has the following configuration in order to solve the above problems. According to the first aspect of the present invention, a socket support base is disposed inside the luminaire main body, the socket is fixed to the socket support base, and a light source having the same socket and a regular polygonal light source case is mounted. The light source is configured such that the top portion of the light source case is in contact with the socket support in a state where the light source is mounted on the socket.
In addition, the support having elasticity is configured so that the light source is in contact with a surface smaller than the maximum number of polygonal surfaces of the light source case while the light source is supported, and the light source further has a hook-shaped engagement portion at one end. It is a support that has a hooked bent piece and has elasticity, and is wrapped around the light source case and supported by a socket support base, and the hooked bent piece of the support is removed from the socket support and the light source is removed. It is.
[0006]
According to a second aspect of the present invention, the light source case in the luminaire according to the first aspect is formed of any one of a regular square, a regular hexagon, and a regular octagon.
[0008]
According to the luminaire described above, the compact fluorescent lamp is securely supported by the socket, the light distribution does not change, and the compact fluorescent lamp can be easily attached to and detached from the socket. it can.

DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to FIGS. In FIG. 1, 1 is a luminaire main body, and 2 is a translucent glove that is provided on the translucent surface of the lower half of the luminaire main body 1 so as to be freely opened and closed. Reference numeral 3 denotes a socket support base arranged at one end inside the luminaire main body 1 and is formed in a plate shape. Further, as shown in FIGS. 2 and 4, the socket support 3 has a latching hole 4 at one end and a bent piece 5 at the other end.
Reference numeral 6 denotes a socket fixed to the socket support 3, and a socket is provided inside the socket body to mount and support a compact fluorescent lamp.
[0010]
A light source 10 is mounted on the socket 6 and is configured using a compact fluorescent lamp. The compact fluorescent lamp has a regular polygonal light source case 11 at one end. The light source case 11 shown in FIG. The light source case 11 shown in FIGS. 2 to 5 is formed in a regular hexagon. The light source case 11 shown in FIG. 7 is configured in a regular octagon.
[0011]
Reference numeral 20 denotes an elastic support, which is configured so as to come into contact with a surface smaller than the maximum number of polygonal surfaces of the light source case in a state where the light source is supported. The non-contact surface is elastically deformed, and the support can be removed from the socket support and the light source can be removed from the socket.
For example, the light source case when the light source case 11 is a regular hexagon will be described with reference to FIGS. As shown in FIGS. 3 and 5, the support 20 has a hook-like engagement portion 21 at one end and an engagement bent piece 22 at the other end. Further, the support 20 is configured to be in contact with the three surfaces 23, 24, and 25 of the light source case 11 and not to be in contact with the other surfaces 26. The non-contact surface 26 is elastically deformed by applying an external force, the support body can be removed from the socket support base, and the light source can be removed from the socket. FIG. 3 shows a state in which the light source is mounted on the socket, and the top portion of the light source case 11 is in contact with the surface of the socket support base.
[0012]
Next, attachment / detachment of the light source to / from the socket in the above-described lighting fixture will be described.
[Work to install the light source]
(1) The light source 10 is mounted on the socket 6 in a state in which the hooked bent piece 22 at one end of the support body 20 hooked on the bent piece 5 of the socket support 3 is opened .
(2) With the light source 10 mounted on the socket 6, the hooked bent piece 22 of the support 20 is hooked on the bent piece 5 of the socket support base 3, and the mounting operation of the light source is completed.
[Work to remove the light source]
(1) the engaging bent piece 22 of the upper end of the support member 20 be out of the bent piece 5 of the socket support table 3.
(2) With the hooked bent piece 22 at the upper end of the support body 20 detached from the bent piece 5 of the socket support base 3, the light source is taken out and replaced with a new one.
(3) After that, the hooked bent piece 22 of the support 20 is hooked on the socket support base 3, and the replacement work of the light source 10 on the socket 6 is completed.
[0013]
【The invention's effect】
According to the present invention described above, there is a special effect that the compact fluorescent lamp is securely supported by the socket, the light distribution is not changed, and the compact fluorescent lamp can be easily attached to and detached from the socket. Also, even if the compact fluorescent lamp is not inserted until it is locked in the socket, there is an effect that the risk of the compact fluorescent lamp falling off from the socket is eliminated.
