Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recessed lighting fixture whose irradiation direction can be freely adjusted, and particularly aims to reduce the depth of embedding.

When using spot lights embedded in the ceiling for bedlights in hospitals, local lighting (spot lighting) in shops and homes, it is necessary to make the irradiation direction flexible. Since the device is driven by a motor or the like, the device has to be buried deep, which sometimes makes it difficult to install it in construction materials in the ceiling. In addition, since the spot light itself is rotated, if the fulcrum B is moved upward in an attempt to reduce the deflection of the instrument A as shown in Figure 1, the light emitting side will deflect significantly and the opening D provided in the bottom panel C will have to be enlarged. On the other hand, if you try to make the aperture smaller, as shown in Figure 2, you will have to move the fulcrum point B downward, which will increase the swing of the instrument A. Normally, in order to equalize the motor torque, the center of the instrument will be lowered. However, the opening in the bottom panel was still large and the ceiling surface could not be finished with a sharp finish.

The present invention has been made in view of these points, and it is an object of the present invention to provide a recessed lighting fixture with a shallow embedding depth and a small opening in the lower panel.

Figure 3 shows an embodiment of the recessed lighting fixture of the present invention. It is installed by Reference numeral 2 denotes a light-gathering spotlight attached to the bottom of the instrument body 1 via a mounting arm 3, which can be rotated vertically with a thumbscrew 4.
When the device is in use, it is fixed so that it emits light approximately horizontally. 5 is a lead wire that supplies electricity to the spotlight 2. Next, 6 is a reflector, and rotating arm 7
The rotary arm 7 is rotated in the horizontal direction by a horizontal rotary motor 8, and the reflector 6 pivotally supported by the rotary arm 7 is rotated in the vertical direction by a vertical rotary motor 9. Rotate to. Therefore, the reflecting mirror 6 can be adjusted to a desired angle with respect to the irradiation of the spotlight 2 by appropriately driving the horizontal rotation motor 8 and the vertical rotation motor 9. In addition, each rotating motor 8, 9
is designed to be driven by well-known remote control.
Reference numeral 10 denotes a light-impermeable lower surface panel having an opening 11 below the reflecting mirror 6, and is configured to cover the lower surface opening of the instrument body 1 in a removable manner using an appropriate method. 12 is the ceiling.

An example of using such an embedded lighting device as a bed light in a hospital is shown in FIG. 4, in which a person 14 sleeping on a bed 13 operates a switch 16 for blinking and changing the direction of illumination provided on a wall surface 15.
For example, a book 17 to be read while sleeping can be appropriately irradiated.

Next, Figure 5 shows the state when replacing the lamp.Since the conventional type has a configuration in which the spot light itself rotates, a gear etc. for driving the spot light is required near the lamp, so it is difficult to replace the lamp. Although it is not easy, when the spotlight 2 does not rotate and only the reflector 6 is rotated as in the present invention, it is easier than the conventional one. If the lamp 18 is pivotally supported by the lamp body, maintenance and inspection are extremely easy because all that is required is to loosen the thumbscrew 4, rotate it, and pull out the lamp 18 from the rear of the lamp body to replace it.

As described above, the present invention allows the irradiation direction to be freely controlled by rotating a smaller and lighter reflector without rotating the spotlight itself, and therefore requires a drive device to move the reflector by remote control compared to when moving a spotlight. The height of the fixture can be reduced by making it more compact, and by making the spotlight almost horizontal, and by attaching the remotely controlled reflector and the spotlight to the fixture itself, the lamp can be When replacing the spotlight, it is easy to handle if you only target the spotlight, and the thermal influence from the spotlight's lamp on the drive unit that moves the reflector can be reduced, reducing the risk of failure of the drive unit. Since the light reflected by the mirror is displaced by an angle twice the displacement angle of the reflecting mirror, the response speed to operations can be increased, and the opening provided in the bottom panel can be made smaller, making it possible to create a clear ceiling surface. There is.
