The light rays inside the substrate 120 propagate to an appropriate distance, and the brightness of the illumination lamp 100 can be higher than expected. In one embodiment, the reflective microstructure 124 has a width to depth ratio of about 10-30, which adjusts the brightness distribution of the luminaire 100. In one embodiment, the reflective microstructure 124 has a width to depth ratio of about 13 to 27, thereby adjusting the luminance distribution of the luminaire 100.

As shown in FIGS. 1 and 2, the light source 130 of the illumination lamp is provided in the accommodation chamber 112 of the external housing body 110 and faces the side light incident surface 123 of the transparent substrate 120 to emit a light beam to the side.

The lighting device may include a circuit board housed in a box-shaped external housing and a circuit component mounted on the board. The lighting device is connected to a commercial AC power source through an adapter, and receives the AC power source to generate a DC output. Therefore, the lighting device can be electrically connected to the light source 130 and provides the direct current output to the light source 130 to control lighting of the light source 130. The lighting device may be mounted outside or inside the external housing body 110 (for example, inside the storage chamber 112).

FIG. 3 is a view showing a cross section of an illumination lamp fixed to a ceiling according to one embodiment of the present invention. In one embodiment, the outer housing body 110 may be fixed to a support surface (eg, a ceiling plate material or a wall) by screws 140. The external housing body 110 may be provided with a plurality of screw holes 113, and the screw holes 113 may be installed outside the external housing body 110. Therefore, the external housing body 110 can be fixed to the support surface by screwing the screw 140 and the screw hole 113 of the external housing body 110. However, the present invention is not limited to this. The external housing body 110 of the illumination lamp may be fixed to the support surface by other fixing elements or auxiliary elements (not shown).

When the lighting fixture is fixed to the ceiling, the outer housing body 110 of the lighting fixture can be mounted on the ceiling support frame, and the size of the outer housing body 110 or at least one length thereof is between adjacent support frames. It is larger than the width of the ceiling opening. Depending on the different specifications of the ceiling, the width of the ceiling opening between adjacent support frames may be 910 mm to 450 mm, for example 910 mm, 900 mm, 600 mm, 590 mm, 455 mm or 450 mm. In this manner, when the lighting fixture is mounted between the ceiling support frames, both sides or at least one side of the outer housing body 110 can contact the ceiling support frames, and both sides or at least one side of the outer housing body 110 are framed. Can be supported. Therefore, by fixing between the external housing body 110 of the lighting lamp and the support frame of the ceiling, the lighting lamp can be mounted on the ceiling, and the light emitting surface 121 where the opening 111 of the external housing body 110 is exposed is between the support frames. Located in the ceiling opening. In one embodiment, the size of the light emitting surface 121 of the luminaire is substantially equal to or slightly smaller than the size of the ceiling opening (or ceiling plate material), for example, 910 mm * 455 mm, 600 mm * 600 mm or 910 mm * 910 mm. There may be. Alternatively, the length of the light emitting surface 121 may be substantially equal to or slightly smaller than the width W of the ceiling opening, for example, 910 mm, 900 mm, 600 mm, 590 mm, 455 mm, or 450 mm. Therefore, the illuminating lamp of the present invention is mounted on the ceiling instead of at least one ceiling plate material, and can provide illumination at the same time.

When the illuminating lamp 100 of this embodiment is used for indoor lighting, for example, the external housing body 110 is mounted on the wall or ceiling of the room, the transparent substrate 120 and the light source 130 are placed, and only the light emitting surface 121 of the transparent substrate 120 is mounted. To expose. When the illumination lamp 100 provides illumination, the light generated by the light source 130 enters the transparent substrate 120 and is primarily reflected by a reflective microstructure 124 or a dot pattern (not shown) on the reflective surface 122, Internal light rays are emitted into the room (external environment) through the light emitting surface 121.

When the illumination lamp 100 provides illumination, the light emitted from the light source 130 passes through the side light incident surface 123 and enters the transparent substrate 120 and propagates inside the transparent substrate 120. The reflection fine structure 124 on the reflection surface 122 can destroy the total reflection propagation of the light beam, and the light beam inside the transparent substrate 120 is reflected outside the light emitting surface 121. At this time, the luminance distribution of the illumination lamp 100 can be adjusted by an appropriate width-to-depth ratio (W / D) of the reflective microstructure 124.

From the above, the illumination lamp of the present invention can be directly mounted on a support surface of a building, for example, a ceiling or a wall, and provides indirect illumination and avoids glare. Since the light beam of the light source is reflected only once and can be emitted as indirect illumination, the loss of light energy can be avoided, the utilization factor of the light beam can be improved, and further the energy saving effect can be achieved.
