Description

[Detailed description of the invention] This invention relates to a downlight for indoor lighting.

Conventional downlights of this type have a reflector fixed inside the outer casing, so to change the irradiation direction, remove the reflector each time, adjust the irradiation direction of the reflector, and reinstall it inside the outer casing. The need arose.

Therefore, with conventional downlights, it is very time-consuming and troublesome to change the irradiation direction, and if the irradiation direction is incorrectly adjusted, it is necessary to remove the reflector and re-adjust it, making the adjustment time consuming. There was an inconvenience that seemed strange.

In order to eliminate this inconvenience, for example,
- As disclosed in Publication No. 5208, a recessed lighting device has a configuration in which a bowl-shaped reflecting mirror is attached to a rotating cover in an inclined state, and the direction of reflection of the reflecting mirror is changed by horizontally rotating the rotating cover. is proposed.

However, in this type of lighting fixture, the tilted opening of the reflector is simply rotated by horizontally rotating the rotating cover, so the light beam from the light source lamp is oriented at a constant angle with respect to the axis of the light source lamp. Therefore, there is a problem in that the elevation angle of the irradiation light beam cannot be adjusted at the stop position of the rotating cover.

This proposal aims to provide a downlight that can eliminate such inconvenience.

The downlight according to the present invention will be explained below with reference to the attached drawings. Fig. 1 is a longitudinal sectional front view showing the inside of the downlight according to the present invention, and in the figure 10 is an outer cylinder with one side open;
20 is a lower reflector, 30 is a holder, 40 is an upper reflector, 50 is a socket, and 60 is a light source lamp.

The outer cylinder 10 is inserted into the ceiling through a mounting hole formed in the ceiling R with the opening facing down. Fixing means for fixing the outer cylinder 10 to the ceiling, for example, a vertical hole 1
1, and a locking means protruding to lock the holding stand 30 on the inner wall of the outer cylinder and prevent it from falling, such as an elastic protrusion made by bending a plate spring. 13, and a decorative edge 14 that abuts the outer surface of the ceiling, and the locking means includes:
The locking means is constructed so as not to hinder rotation of the holding base 30 in the circumferential direction.

In the above embodiment, the locking means is the elastic protrusion 13
However, this locking means may be configured as desired, for example, contrary to the embodiment, a protrusion may be provided on the holding base 30 side, and a groove may be provided on the outer cylinder 10 side. Alternatively, a frame body may be provided on the outer cylinder side to which the holding base 30 is fitted around the entire outer circumference.

The lower reflector 20 is made by obliquely notching a lattice-shaped mirror body on its reduced aperture side, and is attached to the outer cylinder 10 with its enlarged aperture side facing downward. A cylindrical holding stand 30 with upper and lower openings having a groove 31 formed in the circumferential direction so as to engage with the holding stand 30 is fitted onto the outside of the holding stand 30.
are connected and fixed by a fixing piece 21.

The upper reflecting mirror 40 is connected to the holding table 30 by a connecting mechanism 70, and the lower reflecting mirror 2
It is configured to rotate towards and away from the upper opening of the light, and is provided with a hood 41 and a light-shielding holder 42, similar to known downlights.

The connection mechanism 70 includes an upright support piece 71 fixed to the holding base 30 along the high side of the lower reflector 20.
A rotating piece 72 is pivotally attached to the tip of this upright branch 71 and is held in a rotating position by a friction means with high frictional resistance such as a wave washer; It is provided with a mounting piece 73 extending from the rotating end in the direction crossing the axes. Reflector 4
It is configured to move 0.

A socket 50 is fixed to the mounting piece 73, and a light source lamp 6 attached to this socket 50 can be attached to the mounting piece 73.
0 protrudes into the hood 41.

A cord 80 is drawn out from the socket 50, connected to a terminal board 81, and connected to an external power cord via the terminal board 81.

The cord 80 is relaxed in the outer cylinder so as not to interfere with the horizontal rotation of the holding base 30 and therefore the lower reflector 20, so that the grommet 82 and the socket 50 are not located on the same axis. It is desirable to place it.

The downlight of this plan has a lower reflector 20 like this.
A holding stand 30 is fixed to the holding stand 30, and an upper reflecting mirror 40 is rotatably connected to this holding stand 30.
0 is horizontally rotatably locked in the outer cylinder 10, so both the upper and lower reflecting mirrors 20, 40 can be horizontally rotated as one body, as shown in FIGS. 2 and 3.
It has the advantage of being able to freely change the irradiation direction of the downlight, and at the same time, the angle of elevation of the irradiation beam can be changed by rotating the upper reflector 40 at the position where the irradiation direction is set, as shown in Figures 1 and 2. There is also the advantage of being able to adjust the
Since the socket 40 and the socket 50 are constructed as one unit, there is also the advantage that it is easy to install and remove the internal structure within the outer cylinder.

Therefore, when using the downlight of the present invention, there is an advantage that changing and adjusting the irradiation direction is extremely simple and easy, and the internal structure can also be easily handled.
