Description

  The present invention relates to a downlight device. In particular, the present invention relates to a structure of a component base of a downlight luminaire in which the component base and the lighting component are separated so as not to touch the ceiling material and a member for connecting the two is not provided.

  Since the structure of the component base of this type of conventional device is parallel to the ceiling material, the distance between the center of gravity and the fulcrum of the downlight illuminator is increased, and at the same time the rotational moment is increased. In some cases, there was a gap between the reflector and the ceiling material. Therefore, it is necessary to provide a member that connects the component base and the ceiling material. When the member is provided on the component base, there is a problem that it is difficult to attach the downlight lighting fixture.

  Therefore, by bending the component base diagonally downward at an arbitrary angle from the edge of the socket base, the distance between the fulcrum and the center of gravity is shortened, and at the same time, the rotational moment is reduced, so that the member connecting the component base and the ceiling material is Even without this, it is possible to prevent the generation of a gap between the reflector and the ceiling material. As a result, it is not necessary to provide a member for connecting the component base and the ceiling material, and the downlight lighting apparatus can be easily attached.

  The object of the present invention is not to provide a member for connecting the component base and the ceiling material for preventing the gap between the reflector and the ceiling material in the downlight lighting device, and it is easy to mount the downlight lighting device. It is to be.

  In the present invention, in order to solve the above problems, the component base is bent obliquely downward at an arbitrary angle from the edge of the socket base.

  The present invention reduces the rotational moment by bending the component base obliquely downward at an arbitrary angle from the edge of the socket base, thereby preventing the occurrence of a gap between the reflector and the ceiling material. There is no need to provide it. As a result, it is possible to facilitate the installation of the downlight luminaire and to reduce the part cost and the part mounting man-hours.

  An embodiment of the apparatus of the present invention will be described with reference to FIGS. As shown in FIG. 1, the downlight illuminator according to the present invention includes a component base 1, and includes a reflector 2 having an opening on the lower surface side and a lamp introduction hole 7 formed on the side surface in a front portion of the component base 1. 1 is provided with a socket base 4 that is fixed substantially perpendicular to the socket base 1, a socket 5 that is fixed to the socket base 4 is provided, the socket 5 is disposed so as to face the lamp introduction hole 7, and is disposed on the lower surface side of the component substrate 1. And a terminal block 10 disposed on the right side of the lighting component 3, and a pair of convenient support columns 6 fixed on one side lower side and the other side lower side of the reflector 2. The pair of support posts 6 are arranged so as to be asymmetric with each other toward the component substrate 1, and a mounting bracket 11 that can slide up and down is provided in the groove of the support posts 6.

  As shown in FIG. 2, since the lighting component 3, the terminal block 10, the socket base 4 and the socket 5 are mounted, a load MG2 is applied downward to the center of gravity A2 behind the component base 1 and rotates around the fulcrum B2. A moment M2 is generated. For this reason, a force acts downwardly on the rear side of the reflecting plate 2, and a gap is generated in a portion C <b> 2 between the ceiling material 8 and the reflecting plate 2. In order to solve such a problem, conventionally, as shown in FIG. 3, a member 9 connected to the ceiling material 8 is provided at the rear part of the component base 1 to reduce the load MG3 applied downward to the rear of the component base 1. The rotational moment M3 generated around the fulcrum B3 was reduced, and the generation of a gap generated in the C3 portion was prevented. However, if bending is provided at an arbitrary angle from the edge of the socket base 4 as shown in FIG. 1, the distance L1 between the center of gravity A1 behind the component base 1 and the fulcrum B1 becomes shorter than L2 shown in FIG. The rotational moment M1 generated around the fulcrum B1 is smaller than M2, and the generation of a gap in the C1 portion can be prevented, and the member 9 is not required.

  As described above, the structure of the downlight illuminator that does not use the method of providing the member 9 that connects the component base 1 and the ceiling material 8 is provided in order to prevent the occurrence of a gap between the ceiling material 8 and the reflector 2. Can do.
