Abstract

PROBLEM TO BE SOLVED: To provide a luminaire that can avoid darkness. SOLUTION: The luminaire wherein a human body sensor 1 detecting an approaching person 2 to turn on a light source 3 is provided with a secondary light source 4 to steadily be lighted or to be lighted when the light source 3 is off. This luminaire is a down light embedded in a ceiling 5 provided with a fluorescent lamp as the light source 3, and the secondary light source 4 illuminates the fluorescent lamp 3. For secondary light source 4, either a visible light-emitting diode having far less quantity of light than the light source 3 or an ultraviolet light-emitting diode will do. Each human sensor 1 is installed in the undersurface of the ceiling 5 around both ends of a ball 6, respectively, one of which lights and controls every light source 4... all at once via a controller 7 upon detecting the person 2. A reflector 8 covers the light source 3 to lead the reflected lights downward.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a lighting fixture controlled by a human sensor.

[0002]

2. Description of the Related Art In a lighting fixture in which a light source is turned on by detecting the approach of a person by a human sensor, the light is turned off until the person approaches considerably. is there.

[0003]

Even when a person approaches, there is a slight time delay from when the human sensor detects the human body to when the light source is turned on. There was anxiety that had to be done. The present invention has been made in view of such a problem to be solved, and aims to eliminate a dark state.

[0004]

Means for solving the problems are as described in the claims.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described. However, this is merely an exemplary embodiment adopted based on the present invention, and the present invention will be described based on matters unique to the embodiment. Therefore, the technical scope of the present invention should be determined based on the matters stated in the claims and matters substantially equivalent to the matters.

In the illustrated embodiment, an auxiliary light source 4 is provided in a lighting apparatus in which a light source 3 is turned on by detecting that a person 2 has approached by a human sensor 1 and the auxiliary light source 4 is always turned on or the light source is turned on. 3 is turned on when it is not turned on. More specifically, the lighting fixture is a ceiling 5
The auxiliary light source 4 irradiates the fluorescent lamp 3 toward the fluorescent lamp 3. The auxiliary light source 4 may be a visible light emitting diode with a light amount much smaller than the light amount of the light source 3 or an ultraviolet light emitting diode. The human sensors 1 are installed on the lower surface of the ceiling 5 near both ends of the corridor 6, and when one of the human sensors 1 detects the person 2, the light sources 4 are simultaneously turned on through the controller 7. Things. Reference numeral 8 denotes a reflector which covers the light source 3 and guides the reflected light toward the lower surface.

[0007] According to this embodiment, there is no darkness at night or in a corridor where there is no external light, and walking can be performed with ease. Further, when the auxiliary light source 4 illuminates the fluorescent lamp, which is the main light source 3, the fluorescent lamp appears to have afterglow, and since the auxiliary light source 4 is not directly viewed by the person 2, there is an advantage that the user does not feel glare. When the auxiliary light source 4 is an ultraviolet light emitting diode, the fluorescent paint of the fluorescent lamp, which is the main light source 3, emits secondary light, and it looks as if the fluorescent lamp is lit slightly.
There is an advantage that the existence of the auxiliary light source is not conscious.
