Embodiment approach 1

[0053] according to Figure 1 to Figure 4 This embodiment will be described.

[0054] The lighting fixture of this embodiment is a ceiling-embedded LED lighting fixture, and includes: a plurality of (in image 3 In the example shown, 6) the light emitting part 2 is constituted by a light emitting element using an LED chip, that is, an LED element (not shown); the sensor part 3 (refer to image 3 ) has an infrared sensor element that detects infrared rays emitted from the human body; the lighting device (not shown) has a control circuit part (not shown) as a control unit, and the control circuit part is based on the output of the sensor part 3. The power supplied to the light emitting unit 2 is controlled to turn on and off the light emitting unit 2 ; and the device main body 10 has the light emitting unit 2 and the sensor unit 3 disposed therein. Furthermore, the lighting fixture according to this embodiment includes: a base substrate 1 formed in a circular plate shape in pl...

Embodiment approach 2

[0071] The lighting fixture of this embodiment is such as Figure 5 As shown, similarly to Embodiment 1, there is an opening 10a for the device main body 10 to take out visible light emitted from the light emitting unit 2 to the outside, and a translucent panel 32a is arranged to cover the opening 10a. On the other hand, the lighting fixture of this embodiment differs from Embodiment 1 in that the partition wall 41 is integrally formed continuously with the translucent panel 32a. In addition, the same code|symbol is attached|subjected to the same structure as Embodiment 1, and description is abbreviate|omitted.

[0072] The light-transmitting panel 32a is formed into a disc shape, and a through-hole 32c is provided through the central part, and the partition wall 41 is integrally formed with the periphery of the through-hole 32c of the light-transmitting panel 32a. One surface side of the direction protrudes. Here, the light-transmitting panel 32a and the partition wall 41 a...

Embodiment approach 3

[0076] Such as Figure 6 As shown in (a), the difference between the lighting fixture of this embodiment and Embodiment 1 is that the lighting fixture of this embodiment includes: a first base substrate 1 a formed in a disk shape, and a through hole is formed through the center portion. 1aa; and the second base substrate 1b, which is formed in a disk shape, has an outer shape smaller than the through hole 1aa, and is arranged inside the through hole 1aa; the light emitting part 2 is mounted on the first base substrate 1a, and the second base The sensor unit 3 is mounted on the substrate 1b, and the partition wall 41 holds the second base substrate 1b and is mounted on the first base substrate 1a. In addition, the same code|symbol is attached|subjected to the same structure as Embodiment 1, and description is abbreviate|omitted.

[0077] here, as Figure 6 As shown in (b), the partition wall 41 is formed of a material (for example, acrylic resin) whose transmittance is higher...

Abstract

To provide an illumination fixture including a fixture main body in which a light-emitting part and a sensor part that detects an infrared ray are disposed, the illumination fixture capable of reducing an erroneous operation by suppressing an increase in temperature of the sensor part and suppressing the occurrence of disturbance noise in an output from the sensor part due to a change in radiation heat according to the lighting and lighting-off of the light-emitting part. [Means for Settlement] An illumination fixture includes a light-emitting part 2 having an LED element (not shown), a sensor part 3 having an infrared sensor element (not shown), and a fixture main body 10 having the light-emitting part 2 and the sensor part 3 disposed therein. Between the light-emitting part 2 and the sensor part 3 inside the fixture main body 10, a barrier wall 41 that lets visible light emitted from the light-emitting part 2 pass and interrupts an infrared ray emitted from the light-emitting part 2toward the sensor part 3 is disposed, the barrier wall 41 being formed in a shape so as not to interfere with a sensing area of the sensor part 3.

Description

technical field [0001] The present invention relates to a lighting fixture including a lighting device and a light emitting unit having a light emitting element. The lighting device turns on and off the light emitting unit based on an output from a sensor unit having an infrared sensor element. Background technique [0002] In recent years, in response to the demand for energy saving of lighting fixtures, lighting fixtures and lamps having a light-emitting portion constituted by a white light source using a low-power-consumption LED element have been used. [0003] In addition, there is provided a lighting fixture installed in a building, which includes a lighting device for turning on and off a light-emitting part based on the output of an infrared sensor element such as a pyroelectric sensor. When there is no person in the detection area and there is no output from the infrared sensor element, the light emitting part is automatically turned off, thereby reducing power cons...
