Description

  The present invention particularly relates to a lighting fixture that is installed on a mounting surface using an LED as a light source.

Incandescent bulbs and fluorescent lamps have been widely used for ordinary household lighting because of their high illuminance and economy. However, in recent years, the large power consumption has become a problem. For this reason, instead of incandescent bulbs and fluorescent lamps, illumination using LED (Light Emitting Diode) elements that can obtain illuminance equivalent to these with low power consumption has become widespread.

In a fluorescent lamp, for example, electrodes are provided at both ends of a glass tube having an elongated cylindrical shape (straight tube type), and light is emitted by applying an AC 100 V of a commercial power source between the electrodes. For this reason, two pins are provided at both ends, and these pins are locked to terminals provided on the fixture of the fluorescent lamp, whereby the fluorescent lamp is fixed to the fixture. At this time, a commercial power source is connected to the terminal of the fixture, and this pin plays two roles of energizing the fluorescent lamp and mechanically fixing the fluorescent lamp. The electrodes and pins at both ends of the fluorescent lamp are directly connected, and the elongated area between the electrodes at both ends emits light substantially uniformly.

On the other hand, it is a small LED element of about several square mm that directly emits light in the LED lighting apparatus. However, it is preferable that the form of the lighting fixture or the light emitting area has the same extent as that of the fluorescent lamp. For this reason, in LED lighting fixtures, a large number of LED elements are arranged in a direction corresponding to the longitudinal direction of the straight tube in the fluorescent lamp. Unlike a fluorescent lamp, an LED element operates with a low-voltage direct current, whereas it is preferable to use a commercially available power supply (AC 100 V) as a power supply for LED lighting fixtures. For this reason, the LED lighting apparatus generally includes a power supply circuit that converts AC 100V of commercial power into a lower DC voltage. Further, since each LED element and power supply circuit generate heat during operation, a heat radiating plate or the like for performing this heat dissipation is also used.

Since it comprises such a configuration, the LED lighting apparatus is heavier than a fluorescent lamp as a whole. On the other hand, fluorescent lamps and LED lighting fixtures are generally often installed on the ceiling in a house. In such a case, there is a problem that installation of heavy LED lighting fixtures on the ceiling is difficult compared to conventional fluorescent lamps.

In consideration of such points, Patent Document 1 proposes an LED lighting fixture mounting structure. Specifically, an instrument main body having an attachment portion at the end and an end cover for opening and closing the attachment portion of the instrument main body are provided. With such a structure, there is provided a lighting fixture that can have a good appearance and can have good workability with a simple configuration.

JP 2012-66610 A

  However, in the conventional lighting fixture according to Patent Document 1, no consideration is given to the power supply mounting portion. As described above, LED lighting fixtures generally include a power supply circuit that converts AC 100 V of a commercial power source into a DC voltage lower than this, and it is necessary to secure a power supply mounting portion. When it is going to secure a power supply mounting part separately in the conventional lighting fixture which concerns on patent document 1, a favorable external appearance will be inhibited.

The present invention has been made in view of such problems, and an object thereof is to provide a device for solving the above problems.

In order to solve the above problems, the present invention has the following configuration. That is, the lighting fixture according to the present invention includes a long fixture body having a mounting portion, a body cover that covers a light emitting element disposed in the longitudinal direction of the fixture body, and an area outside the mounting portion of the fixture body. A power supply for supplying electricity to emit light from the light emitting element and an end cover that is slidable in a longitudinal direction of the instrument main body and covers the mounting portion and the power supply, the end cover being the instrument main body When the slider is slid in the direction opposite to the center in the longitudinal direction, the attachment portion is exposed, but the movable range of the end cover is limited so that the power source is not exposed.

  Since the present invention is configured as described above, it improves workability when attaching lighting fixtures to ceilings and walls, provides a good appearance, and also considers safety during work. Lighting equipment can be provided.

It is the perspective view which looked at the lighting fixture which concerns on this invention from diagonally lower side. It is AA sectional drawing of the lighting fixture which concerns on this invention. It is the perspective view which removed the edge part cover of the lighting fixture which concerns on this invention. It is the figure which looked at the lighting fixture which concerns on this invention from the lower side. It is the figure which looked at the lighting fixture which concerns on this invention from the installation surface side to a ceiling etc. (A) is a state in which the end cover is closed, and (b) is a state in which the end cover is open.

FIG. 1 is a perspective view of a lighting fixture 1 according to the present invention as viewed obliquely from below. In the direction of the arrow in FIG. 1 (upper side), for example, a ceiling exists if indoors, and the direction opposite to the arrow (lower side) is the ground side. The lighting fixture 1 is attached to the ceiling or wall surface which exists in the direction of the arrow in FIG.

The structure of the lighting fixture 1 includes a main body cover 4 having translucency in the fixture main body 2. And the end cover 3 which does not have translucency is provided in the both ends of the instrument main body 2. FIG.

A cross-sectional view taken along the line AA of FIG. 1 is shown in FIG. The upper side of FIG. 2 is a side to be attached to a ceiling or a wall (an installation surface on the ceiling or the like). The fixture body 2 is provided with a substrate 12 on which the light-emitting element 5 is mounted. Light emitted from the light-emitting element 5 passes through the light-transmitting main body cover 4, and the lighting fixture 1 emits light.

Next, the structure and function of the end cover 3 that is an essential part of the present invention will be described with reference to FIGS.

FIG. 3 is a view showing a state in which the end cover 3 of the lighting fixture 1 according to the present invention is removed. When the luminaire 1 is actually used, the end cover 3 is structured so as not to be removed. Here, in order to explain the internal structure, a description will be given with reference to a state in which the end cover 3 is removed. A power source 6 is disposed at a location covered by the end cover 3, that is, at the end of the instrument body 2. Further, in the region sandwiched between the power source 6 and the main body cover 4, an instrument main body attachment hole 7 is formed as an attachment portion for attaching the instrument main body 2 to the ceiling or the like, and a cable through hole 8 is formed next to the instrument main body attachment hole 7. A connector 9 is installed between the power source 6 and the cable through hole 8.

When the lighting fixture 1 is attached to the ceiling or the like, it is attached to the fixture main body attachment hole 7 using a bolt or the like. The cable through hole 8 is a hole through which a cable (not shown) is passed in order to take in a commercial 100 V AC voltage applied to the power source 6 from the outside of the lighting fixture 1, and the cable is connected to the connector 9. The power source 6 converts a commercial 100 V AC voltage taken from the outside into a DC low voltage, and causes the light emitting element 5 to emit light via the substrate 12.

FIG. 4 is a view of the luminaire 1 according to the present invention as viewed from below, and shows a state in which the end covers 3 at both ends are opened. The end cover 3 can be opened and closed by sliding in the longitudinal direction of the instrument body 2. Note that when the end cover 3 is slid in the direction opposite to the center of the instrument body 2 in the longitudinal direction, the end cover 3 is opened. On the other hand, when the end cover 3 is slid toward the center of the instrument body 2 in the longitudinal direction, the end cover 3 is in a closed state. In the closed state, as shown in FIG. The edge of the end cover 3 is closed so as to cover the edge of the main body cover 4.

As shown in FIG. 4, even when the end cover 3 is fully opened, the power source 6 disposed at the end of the instrument body 2 is not exposed to the outside. Exposed to the outside are a part of the fixture body mounting hole 7, the cable through hole 8, and the connector 9 used when the lighting fixture 1 is attached to the ceiling or the like. On the other hand, the power source 6 is kept covered by the end cover 3. By doing so, it is possible to avoid a risk that an operator who tries to attach the lighting device 1 to the ceiling or the like touches the power supply 6 accidentally and is injured.

FIG. 5 shows the structure of the slide portion of the end cover 3 as seen from the installation surface side of the lighting fixture 1 according to the present invention on the ceiling or the like. FIG. 5A shows a state in which the end cover 3 is closed, and FIG. 5B shows a state in which the end cover 3 is slid and opened. When viewed from the installation surface side on the ceiling or the like, the end cover 3 is formed with a long hole 10. On the inner edge side of the long hole 10, for example, a screw 11 is arranged as a slide control unit that is fixed to the end of the instrument body 2 and stops the slide of the end cover 3.

When the end cover 3 is in a closed state, the screw 11 is located at one end in the long hole 10 (that is, the right side in FIG. 5A), but the end cover 3 is opened. 5b, as shown in FIG. 5 (b), the slide of the end cover 3 stops by contacting the other end of the long hole 10 (that is, the left side in FIG. 5 (b)). It has become. This structure prevents the end cover 3 from opening too much and exposing the power source 6.

The long hole 10 is thin enough to prevent the operator's finger from being completely inserted, and care is taken so that the operator does not accidentally insert the finger into the long hole 10 and touch the power source 6.
