Abstract

<P>PROBLEM TO BE SOLVED: To provide a luminaire used as a substitute light source for a round fluorescent lamp, and small in environmental burdens. <P>SOLUTION: The EL luminaire uses, as a power source, a battery housed in a tube having the same shape as that of a round fluorescent lamp, makes both surfaces of EL of a diffusion surface light source arranged on the front and back curved surfaces of the tube and excelling in luminous efficiency emit light at the same time or makes only one surface thereof emit light separately, and is characterized by being repeatedly used, having a long service life and being small in environmental burden. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to an EL lighting apparatus that has the same shape as a round fluorescent lamp, can be carried as a substitute for a power failure using a stored battery as a power source, and can emit light separately on the front and back curved surfaces.

  Conventionally, a round fluorescent lamp using an AC power source has been widely used as a lighting fixture. In particular, it has become a common light source for general illumination such as a ceiling light with a milky white cover on a fluorescent lamp. As a new diffused light source, an EL technology that emits surface light has been proposed.

There were the following problems.
(B) Since it emits light with an AC power supply, it could not be used in the event of a power failure or failure of equipment such as a ballast.
(B) Because it requires power cords and parts for light emission, it was not suitable for moving and carrying.
(C) The light emitted from the fluorescent lamp was sharper than natural light and could not be seen directly, and was not kind to the eyes.
(D) The glass tube generated heat with light emission, and the light emission efficiency with respect to power consumption was poor.
(E) Fluorescent lamps with a short product life and a long life had to be replaced and discarded.
(F) Fluorescent lamps contain mercury vapor, which has a large environmental impact during disposal.
The present invention is intended to solve the above problems.

  This is an EL lighting fixture that uses a battery housed in a tube having the same shape as a round fluorescent lamp as a power source and emits light on both the front and back surfaces of the tube simultaneously or separately on only one surface.

  The present invention is an EL lighting device having the same shape as that of a round fluorescent lamp, and uses a battery housed in the tube as a power source, so that it can be used as a substitute for a round fluorescent lamp even in the event of a power failure. Can be carried around. In addition, EL illumination does not generate heat during light emission, has good light emission efficiency with respect to power consumption, and is friendly to the eyes with a diffused light source that is closer to natural light. Since the front and back sides can emit light separately, they can be used as lighting fixtures that can further contribute to power saving and as indirect lighting fixtures. EL lighting fixtures that use batteries as a power source can contribute to a recycling-oriented society as a light source that can be used repeatedly and that has a low environmental impact.

Hereinafter, an embodiment of the present invention will be described with reference to FIG.
(A) The EL light emitter (2) is fixed and sealed inside the optical cover (1) having the same front and back curved surfaces as the round fluorescent lamp.
(B) A stopper cover (5) equipped with a stopper (4) having a mechanism for opening and closing and fixing each battery housing for front and back light emission is joined to the frame (3).
(C) The structure of the frame (3) by connecting the front light emitting battery housing (6a) and the back light emitting battery housing (6b) to the switch portion (7) with a power button for lighting and front / back light emission switching. To join.
(D) A battery (8) is attached to each battery storage part (6a) (6b) for front and back light emission.
(E) Each light emitting part (1) (2) on the front and back surfaces is joined to the structure of the frame (3) with the battery attached, and connected to the electrode of the switch part (7). Join.
The present invention is constituted as described above.
When this is used, the battery storage unit with the light emitting battery is fixed with a stopper. When the power button is pressed, both the front and back lights up. Press again to turn off the back and enter power saving mode. If pressed further, the indirect illumination mode is activated by turning on only the back surface, and turns off when pressed once more.
