Abstract

(57) [Summary] [Purpose] The purpose of the present invention is to increase the illuminance, reduce the power consumption, and enable the lamp to be replaced by one person, with the same size as the conventional body. A light source having a socket (1), a fluorescent lamp (2), a socket (1), a socket (1), a fluorescent lamp (2), and a socket (1) arranged linearly and closely in order in the main body. A reflector (3) having a mirror-finished reflection surface is provided above each light source, and a power supply (4) driven at a lamp rated power consumption or less is provided in the main body.

Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 This invention relates to a ceiling light.

[0002]

[Prior art]

 Conventional ceiling fluorescent lamp luminaires include one for providing one bar-shaped fluorescent lamp and two for providing two bar-shaped fluorescent lamps in parallel.

[0003]

[Problems to be solved by the invention]

 This has the following problems. (B) When the power consumption of the lighting equipment is reduced, the illuminance is reduced. (B) Light emitted upward from the light source hits the ceiling, or is reflected by the reflector and hits the light source, and effective brightness is not obtained. (C) In order to attach and detach a fluorescent lamp with a length of 2 m or more, it is difficult for one person to position the socket relative to the socket. The present invention has been devised to solve the above-mentioned problems. Compared with the conventional system, the main unit has the same size, increases the illuminance, reduces the power consumption, and allows the lamp to be replaced by one person. It is intended to be.

[0004]

[Means for Solving the Problems]

 The ceiling fluorescent lighting device of the present invention includes a fluorescent lamp, a socket, a reflector, a power supply unit, and a main unit.

[0005]

[Action]

 The light emitted radially upward from the fluorescent lamp is reflected by each of the bent planes and is irradiated downward without hitting the fluorescent lamp. Each fluorescent lamp is driven by the inverter of the power supply at the lamp rated power consumption or less.

[0006]

【Example】

 Hereinafter, embodiments of the present invention will be described. The socket (1), the fluorescent lamp (2), the socket (1), the socket (1), the fluorescent lamp (2), and the socket (1) are sequentially and closely arranged in a straight line. Two reflectors (3) are arranged in parallel, and the reflection surface is mirror-finished above each light source. The power supply (4), which operates at less than the rated power consumption of the lamp, is provided in the body. The reflector has one bent protrusion, two or more reflecting surfaces, and two or more bent recesses, and a straight line that passes through the center of the fluorescent lamp, connects each bent part, and passes through each bent part to the fluorescent lamp. A plane following each bent part shall be provided at right angles to a straight line that halves the intersection angle with the tangent straight line. Each fluorescent lamp is driven by the inverter in the power supply at the rated power consumption or less. Each fluorescent lamp is composed of a rod-shaped fluorescent lamp that is about half as long as the conventional rod-shaped fluorescent lamp and about half the rated power consumption.

[0007]

[Effect of the invention]

 It has the same size as a conventional ceiling lighting fixture body, and can reduce power consumption and increase illuminance. Fluorescent lamp positioning and replacement is possible by one person.
