Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture in which a base installed on an installation surface and a lamp body detachably attached to the base are combined.

[0002]

2. Description of the Related Art Conventionally, when a general downlight is installed as a lighting fixture, for example, a step of removing a lamp and a reflector from a downlight fixture main body is previously formed on an installation surface such as a ceiling surface. A step of connecting the power line drawn from the embedding hole to the terminal block of the instrument body,
Step of inserting the instrument body into the embedding hole, pull down the holding piece placed on the side surface of the instrument body with the fingertip inserted into the inside of the instrument (inner space for mounting the lamp and reflector), and engage with the back edge of the embedding hole. The step of combining and the step of attaching the reflector and the lamp to the instrument body are sequentially performed.

However, in such a downlight, it is necessary to push down the instrument body with one hand while pulling down the holding piece from the inside of the instrument with the other hand, and further pulling down the holding piece. In this case, the lamp and the reflection plate must be attached and detached, which causes a problem that it takes time and effort for the construction.

Also, after connecting the power supply line drawn out from the embedding hole formed in advance on the installation surface to the terminal block of the instrument body, the instrument body is inserted into the embedding hole to insert it into the embedding hole. There is a downlight having a structure in which a leaf spring is projected from a side surface of an instrument body in response to an operation and is engaged with a rear edge portion of an embedding hole. With this structure, since the locking to the installation surface can be performed at the same time as the insertion operation of the instrument body, the labor and time required for construction can be reduced as compared with the structure in which the holding piece is used for locking.

[0005]

In the structure in which the leaf spring is engaged as described above, the labor and time required for construction are reduced as compared with the structure in which the sandwiching piece is engaged. When stopped, the locked state tends to become unstable. If the elasticity of the leaf spring is strengthened and the locking is strengthened, it becomes difficult to pull out the leaf spring against the elasticity of the leaf spring when removing the instrument body from the embedding hole for maintenance or instrument replacement. Further, if the device body is forcibly pulled out against the leaf spring, the leaf spring may be depressed and it may be difficult to reattach it.

The present invention has been made in view of the above points, and an object thereof is to provide a lighting fixture which can reduce the labor and time required for construction and can stabilize the locked state on the installation surface. To do.
