Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture with a sensor.

[0002]

2. Description of the Related Art Conventionally, there is an illumination device with a sensor that turns on a lamp as a light source when an infrared sensor detects a movement of a person. One example is shown in FIG.
An embedded lighting fixture 30 and the like disclosed in Japanese Patent Application Laid-Open No. 2000-188012 shown in (b) are known. This lighting fixture 30 includes a cylindrical fixture body 31 having an outer flange at an opening 32, a lamp 33 as a light source housed inside the fixture body 31, a circular body cover 34 covering the opening 32, and a body. The cover 34 includes a translucent opening 35 and a sensor detector 36. The translucent opening portion 35 and the sensor detection portion 36 are arranged side by side in the diameter direction of the main body cover 34.

[0003]

However, the above-described conventional lighting device with a sensor 30 has the following problems.

In the conventional example shown in FIG. 11, in order to give priority to the reliable operation of the sensor, a translucent opening 35 and a sensor detector 36 are provided in the diameter direction of a main body cover 34 that covers the opening 32 of the instrument main body 31. Since they are arranged side by side, the device body 3
Compared with the width of the first opening 32, the light-transmitting opening 35 actually irradiated with light becomes extremely narrow. Therefore, when it is attempted to make the sensor-equipped lighting fixture the same size as the sensor-equipped lighting fixture, the translucent opening 35, which serves as a light irradiation port of the sensor-equipped lighting fixture, irradiates the light of the sensor-less lighting fixture. Since it is smaller than the opening 32 serving as a mouth, there is a problem in that the amount of light changes. On the other hand, when trying to obtain the same amount of light with the sensor-equipped luminaire with respect to the sensor-less luminaire, the sensor-equipped luminaire is adjusted to align the translucent opening 35 of the sensor-equipped luminaire with the opening 32 of the sensor-less luminaire. There is a problem in that the size of the main body of the luminaire must be increased, the shape of the luminaire is changed, and when a large number of luminaires are used in combination, the overall unity of appearance is impaired, which is not preferable.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a lighting fixture having a sensor function and having substantially the same shape as the sensorless lighting fixture.

[0006]

In order to achieve the above-mentioned object, the present invention provides a device main body provided with a light source and a control block for controlling the lighting of the light source, and a device body which covers the periphery of the light source and is attached to and detached from the device main body. In a lighting fixture including a reflector that is movably attached and a sensor detection unit that transmits a signal for operating the control block, the sensor detection unit is arranged so that the sensor light receiving unit faces the space facing the light transmitting opening. It is provided near the periphery of the translucent opening of the reflection plate, and the sensor detection unit and the control block are detachably connected by wiring, and the sensor detection unit is detachably attached to the instrument body. It is a feature.
