Disclosed is a lighting device using LED elements as light sources, said lighting device having improved safety due to a reduction in weight and also due to prevention of use in incorrect fixtures. A plurality of lighting devices can be seamlessly put together, thereby illuminating a large area without creating shadows. The lighting device (A) is provided with: LED elements (1); a base member (3) in which the LED elements (1) are arranged and mounted; a cover member (4) inside which the base member (3) is fitted and through which light emitted from the LED elements (1) passes; and a fixture (5) into which the cover member (4) is slid and attached, said sliding taking place in the direction in which the LED elements (1) are arranged. The cover member (4) is supported by the fixture (5) along the entire range of movement through which the cover member can slide against the fixture (5). This results in the cover member (4) being securely supported by the fixture (5), so the danger of the cover member coming loose from the fixture (5) and falling, due to the weight of the cover member or vibration, is low.
The present invention relates to an illumination device using an LED element as a light source.
Fluorescent lamp-type lighting devices have been widely used in homes and offices. In general, a fluorescent lamp is a light source in which an electrode is disposed in a glass tube filled with a predetermined gas, and ultraviolet rays generated by discharge are applied to a fluorescent material applied on the inner surface of the glass tube to convert it into visible light. In many cases, circular fluorescent tubes are mainly used in homes, and rod-shaped fluorescent tubes are used in offices.
The rod-like fluorescent tube is also called a straight tube type, and includes a glass tube coated with a fluorescent material on the inner surface and electrodes attached to both ends of the glass tube in the longitudinal direction. Two electrodes protrude outward from both ends of the glass tube and are connected to the base of the fluorescent lamp fixture. The fluorescent tube obtains electric power from the fluorescent lamp fixture through these electrodes and the base.
On the other hand, since a light emitting diode (hereinafter referred to as LED) can irradiate light with low voltage and high efficiency, its use in a lighting device has been attracting attention in recent years. An illumination device using an LED can reduce power consumption as compared with a light bulb using a fluorescent lamp or a filament.
An example of a lighting device using LEDs as described above can be seen in Patent Document 1. The LED-type fluorescent lamp illumination device described in Patent Document 1 is an illumination device that is structurally compatible with a conventional straight tube fluorescent lamp using an LED as a light source. The structure corresponding to a conventional fluorescent tube has a rod-shaped cylindrical housing in which a plurality of LED elements are arranged and mounted, and a print base member is provided, and electrodes protrude from both ends to the outside.
Japanese Patent No. 4156657 (5th page, FIG. 1)
As described above, an illuminating device that is structurally compatible with a conventional straight tube fluorescent lamp, such as the LED type fluorescent lamp illuminating device described in Patent Document 1, has electrodes on both ends of the fluorescent tube as described above. However, the base corresponding to the electrode of the fluorescent tube of the lighting fixture that supports the fluorescent tube is provided. Accordingly, when a plurality of the lighting devices are arranged on the ceiling or the like in a row in the longitudinal direction of the fluorescent tube, there is a high possibility that the amount of light at the base portion is reduced and shadows are formed.
Also, the straight tube type fluorescent tube constructed using LEDs is heavier than the conventional fluorescent tube. And since this LED type fluorescent tube is supported only at the location of the two caps of the instrument, there is a concern that the risk of falling becomes high. In particular, a fluorescent tube exceeding 2 m used in a large room has a higher risk of dropping.
Also, when LED fluorescent tubes are used with conventional fluorescent lamp fixtures, work may be performed to remove ballasts necessary for conventional fluorescent lamps. Although the conventional fluorescent tube cannot be used for the appliance subjected to this construction, there is a possibility that the conventional fluorescent tube is erroneously attached. In addition, there is a possibility that the LED fluorescent tube is mounted on a conventional fluorescent lamp fixture equipped with a ballast.
The present invention has been made in view of the above points, and is an illuminating device using an LED element as a light source. The use of a wrong instrument prevents and reduces the weight, thereby improving safety.

It was decided to be supported by the instrument over the entire area or at multiple locations.
According to this configuration, since the cover member is firmly supported by the instrument, the risk of falling off the instrument due to weight or vibration is low. It is also possible to prevent erroneous use such as mounting an LED illumination device on a conventional fluorescent lamp fixture. Furthermore, since the use of electrodes and bases seen at both ends in the longitudinal direction of conventional fluorescent lamps and fluorescent lamp fixtures can be eliminated, weight reduction can be achieved and seamlessness can be expected when a plurality of lighting devices are arranged in series.
Further, in the illumination device having the above-described configuration, the cover member includes a groove portion on an inner surface thereof, and the base member is mounted by being slid along the groove portion.
According to this configuration, the base member can be easily attached and detached by sliding the groove with respect to the cover member, and the replacement work is simple.
Further, in the illumination device having the above-described configuration, the cover member has a bowl shape.
According to this configuration, the back side of the base member can be opened, and heat generated from the LED element itself or the power supply unit that supplies power to the LED element can be released from the back side of the base member. Further, it is possible to further reduce the glare feeling by increasing the distance between the cover member and the LED element.
Further, in the lighting device having the above-described configuration, the cover member includes a support portion that engages with the instrument over the entire surface in the sliding direction or at a plurality of locations on the outer surface thereof.
According to this configuration, the cover member can be easily attached to and detached from the instrument using the support portion, and the replacement work is simple.
Further, in the lighting device having the above configuration, the support portion is formed in a groove shape.
Further, in the lighting device having the above configuration, the support portion is formed in a ridge shape.
Further, in the illumination device having the above-described configuration, the tip of the support portion is formed in a U shape that is bent toward the cover member main body.
According to this configuration, the cover member can be securely held by the instrument.
Further, in the lighting device having the above-described configuration, the cover member and the appliance are configured as a single unit.
According to this configuration, it is possible to further reduce the weight of the lighting device. Since the appearance shape is clearly different from that of the conventional fluorescent lamp, there is less risk of mistakenly mounting the conventional fluorescent lamp or mounting the conventional fluorescent lamp. In addition to these, a wide space can be secured on the back surface side of the base member, and adverse effects due to heat generated from the LED element itself or the power supply unit can be avoided.
According to the configuration of the present invention, in an illuminating device using an LED element as a light source, the safety is enhanced by preventing the use of an incorrect instrument and reducing the weight, and the plurality of them are seamlessly arranged. Thus, it is possible to provide an illuminating device capable of irradiating light over a wide range without creating a shade.
