Description

[Detailed description of the invention]

[Technical field to which the present invention pertains] The present invention relates to an interior that is not suitable for ordinary incandescent lamps or fluorescent lamps, and is installed in a dark place such as a shelf furniture, a dressing room, a closet, a Buddhist altar, and the like. It relates to safe and long-life lighting equipment for lighting.

2. Description of the Related Art Conventionally, a light source used for a downlight is a 100 V, 30 W mini-reflex bulb shown in FIG. 7, a 100 V, 15 W or 20 W Natsume bulb shown in FIG. 8, or a commercial power supply 100 V. There were 12V and 10W xenon bulbs and 12V and 20W mini-halogen bulbs that required a transformer to transform the voltage to 12V, all of which were large in size and used a single point light source.

[Problems to be Solved by the Invention] Conventional downlights are all large in size and have a single point light source. Since the light beams are strong and the dark shadows are dark, articles on the dark side are difficult to visually recognize. In addition, there is a problem that the light source may generate heat due to power consumption and may be overheated, and the bulb used is short, and its life is short, which is uneconomical. In the case of a conventional light source, a downlight that uses a Natsume electric bulb with a commercial power supply of 100 V has a large size, and it is difficult to replace it because the light bulb is in a horizontal position. high. In addition, conventional downlights using xenon bulbs and mini-halogen bulbs require a transformer. For downlights using G4 type mini-halogen bulbs or downlights using G4 type xenon bulbs, 12V specifications are required. Therefore, a transformer for transforming the voltage to 12 V is required, and the illuminance is high, but high heat is generated.

[Means for Solving the Problems] The downlight using a light-emitting diode according to the present invention does not require a transformer, can be directly connected to a commercial power supply of 100 V AC, and has extremely low power consumption. It is the smallest illuminator formed on a planar light source using many energy-saving, long-life light emitting diodes that generate little heat.

That is, according to the present invention, a reflector having a plurality of columns is provided with a number of concave cone-shaped reflection surfaces, and a support cylinder fitting hole is provided in a deep portion of the cone-shaped reflection surface. The diode support cylinders each fitted with a light emitting diode at the tip are fitted into the fitting holes. The reflecting plate is connected to a substrate to which a power line connected to a commercial power supply of AC 100 V is connected by the plurality of columns 6, and is fitted in a main body case having a mounting edge with the light emitting diode facing. Things.

Embodiment of the Invention As shown in FIG. 1 and FIG. 4, the present invention relates to fitting of support cylinders, which are respectively formed in a deep part of a large number of concave cone-shaped reflecting surfaces 4 provided on a reflecting plate 3. The light emitting diodes 7 mounted on the diode support tube 8 are fitted into the holes 5, respectively, and connected to the substrate 9 connected to the electric wire 10 leading to the commercial power supply by the plurality of columns 6 protruding from the reflector 3. In this state, the light emitting diode 7 is housed in the main body case 1 with the light emitting diode 7 facing the front side. Therefore, since a large number of light emitting diodes 7 are used as the light source, a planar light source is formed, and the illuminance is not inferior to that of a conventional light source such as a Natsume bulb. Also, since the light source is the light emitting diode 7, it is safe because there is almost no heat generation, and it does not break like a conventional bulb, so it has a long life and can be used semi-permanently without replacing the bulb. It is economical.

[Embodiment] A front view of FIG. 1, a right side view of FIG. 2, and a rear view of FIG. 3 show an embodiment of the present invention. According to the present invention, as shown in FIGS. 5 and 6, a large number of concave cone-shaped reflecting surfaces 4 are provided on a reflecting plate 3 having a plurality of columns 6, and a support tube is fitted into the deep portion of the cone-shaped reflecting surface 4. Drill holes 5. As shown in FIGS. 1 and 4, a diode support tube 8 having a white light emitting diode 7 mounted at the tip thereof is fitted into the support tube fitting hole 5. As shown in FIG. 4, the reflecting plate 3 in this state is connected to the substrate 9 to which the electric wire 10 connected to the commercial power supply of AC 100 V is connected by the column 6, and the white light emitting diode 7 is placed on the surface side. The main body case 1 having the mounting edge 2 is fitted. The case body 1 has a ventilation hole 11 on the back surface, and a mounting hole 12 is formed in the peripheral edge of the front surface.

[Effects of the Invention] The present invention illuminates the interior of a shelf furniture, a wardrobe, a closet, a Buddhist altar, and the like. It is the smallest downlight configured for the light source. Therefore, unlike conventional bulbs, the light beam is soft, there is almost no heat generation, and there is no danger and safety. It is a downlight that is particularly suitable for use in homes for the elderly.
