Figure 1 (A) shows a view from above the frame according to an embodiment of the present invention, Figure 1 (B) shows a view from below the frame according to an embodiment of the present invention. Referring to the drawings, the recessed lighting device according to an embodiment of the present invention is installed by embedding in the ceiling of the facility, and includes a printed circuit board, a body and a diffusion plate.

In the recessed lighting apparatus, a panel support frame having a rectangular shape in a matrix shape is installed on a ceiling of a facility, and a panel is attached to a rectangular area defined by the panel support frame. Here, the size of the square shape depends on an unspecified standard.

The printed circuit board 100 has a wiring pattern for supplying electricity to at least one LED on one surface thereof, and at least one LED (LED) is electrically connected to an end of the wiring pattern. On one surface of the printed circuit board on which the wiring pattern is formed, an insulating layer for additionally shorting and protecting the wiring patterns is additionally formed. When electricity is supplied to the LED which is the light source, the LED generates heat together with the emitted light. Therefore, it is desirable to select a material having a relatively good thermal conductivity for the printed circuit board.

The LED mounted on the printed circuit board includes a light emitting diode chip that emits light therein and a resin including a phosphor formed on an upper side of the light emitting diode chip. Light generated by the light emitting diode chip passes radially through the resin. Here, the presence or absence of the phosphor and the color type of the phosphor may be selected according to the needs of manufacturers and users. In general lighting, it is possible to select a light source that emits white light.

The diffusion plate 200 is positioned below the LED, and is formed of a transparent material such as polymethly methacrylate (PMMA), polycarbonate (PC), glass, and diffuses light emitted from the LED. In the present invention, as the diffusion plate, a material having flexibility is selected.

The frame 300 includes an inner protrusion 310 to which a printed circuit board is coupled, a main body 320 having a recess, an expansion body 330, and a coupling part 340 fixed to the ceiling. The protruding portion, the main body portion, the expansion body portion and the coupling portion are successively formed integrally. The body may be formed of a plastic material such as PMMA, PC, ABS, PS, or the like, and may be integrally formed by vacuum forming.

The main body portion 320 has a rectangular cylindrical shape and has a shape that gradually widens from the upper side to the lower side. In addition, the upper end of the main body portion is provided with an inner protrusion 310 protruding at right angles in the inner direction. The inner protrusions are formed by four inner protrusions bent inward toward the center of the main body portion.

In the exemplary embodiment of the present invention, the main body portion is formed to be gradually widened from the upper side to the lower side, but the upper side and the lower side may have the same size. When formed in this way, it is obvious that the main body has a rectangular cylindrical shape perpendicular to the ground.

The printed circuit board is coupled to the upper end surface 311 of the inner protrusion 310. Herein, the coupling between the inner protrusion and the printed circuit board may be formed by screw coupling. To this end, one or more screw holes may be formed in the inner protrusion.

The printed circuit board is a part of the energy that is not converted to light by the operation of the LED appears as heat. Heat generated in the LED may be transferred to the inner protrusion through the printed circuit board. Although not shown, in order to prevent this, the inner protrusion and the printed circuit board may be coupled through a heat shield plate. In addition, a heat sink having a heat dissipation fin may be coupled to an upper side of the printed circuit board for rapid heat dissipation.

In addition, the lower side of the main body portion is provided with a groove portion 321 for fixing the diffuser plate for diffusing the light emitted from the LED. The recess is fixed to the diffusion plate. The groove size of the groove is the same as that of the diffuser plate. In the state in which the frame is disposed perpendicular to the ground, the diffusion plate is fixed by being inserted upward from the lower side of the main body of the body. The fixing of the diffusion plate is possible because the diffusion plate is a flexible material. 2 (B) and 2 (C) are diagrams showing the T portion of FIG. 2A in detail.

Referring to the portion indicated by the arrow in Fig. 2C, the portion raised on the lower side of the groove portion is somewhat inward compared to the portion shown by extending the inner side of the main body portion. Therefore, the diffusion plate can be easily fitted in a somewhat bent state.

The expansion body portion 330 has a predetermined inclined angle in the outward direction from the main body portion. It is preferable that the angle A formed by the expansion body part and the main body part forms an obtuse angle. Preferably it has an angle of 95 degrees to 110 degrees. If it is larger than vertical and smaller than 95 degrees, the lower end of the groove portion of the main body portion protrudes and becomes prominent, causing visual discomfort. The illumination efficiency is lowered away from the dimming target.

On the other hand, the ceiling of the facility is formed with a panel support frame in a matrix shape, the panel support frame has a defined rectangular installation area. The light emitting region, which is a region defined by the plurality of LEDs mounted on the printed circuit board, is the same as the diffusion region. Here, the diffusion region refers to the size of the diffusion plate. The diffusion body means a component provided in a region other than the diffusion region in the installation region.

Hereinafter, referring to FIG. 3, the coupling part of the frame of the present invention will be described. FIG. 3B is a view showing part E of FIG. 3A in detail. The coupling part 340 is fixed to the panel support frame (PM) and / or panel (P) is installed in the facility, and performs a function of firmly fixing the lighting device to the fixed object.

Coupling portion according to an embodiment of the present invention includes a flat portion 341, the coupling portion fixing groove 342 and the finishing protrusion 343. Referring to FIG. 3, four coupling part fixing grooves are formed in the flat part of the coupling part, and the coupling part may be coupled to the panel by using screws, or the coupling part may be screw-coupled with the panel support frame and the panel. In this case, the coupling part fixing groove is formed to be recessed inwardly so that the screw head is embedded in the fixing groove, and may include a screw hole for screwing. In addition, the edge of the coupling portion is formed with a closing protrusion in an upward direction to achieve a complete sealing with one surface of the panel. The finishing protrusion has an advantage of preventing the inflow and outflow of foreign substances such as dust.

4, a lighting apparatus according to another embodiment of the present invention will be described. Compared to the above embodiment, only the structures of the printed circuit board and the frame are different, and the diffusion plates are the same.

First, the printed circuit board of the lighting apparatus according to the embodiment of the present invention has a quadrangular shape, and a central LED and a peripheral LED are mounted. The light emitted from the center LED is transmitted through the diffuser plate and emitted in the direct direction ML. Light emitted from the peripheral LED is emitted in a lower direction SL through the inside of the frame. The light path of the light from the peripheral LED is described in detail in the description of the frame for the lighting device.

On the other hand, the peripheral LED changes the light based on the signal detected by the illumination sensor (not shown) provided separately. Specifically, when the illuminance sensor is installed in the ceiling adjacent to the lighting device and the signal detected from the illuminance sensor is lowered, the amount of light emitted from the peripheral LED is increased. On the contrary, when the signal detected from the illuminance sensor becomes high, the amount of light emitted from the peripheral LED is reduced.

In contrast, the central LED always emits a uniform amount of light. Therefore, the central LED emits uniform light, and the peripheral LED emits light that changes according to the surrounding environment.

On the other hand, the frame for an illumination device according to an embodiment of the present invention is formed of a material capable of transmitting light to the inside. For example, the material capable of transmitting light to the inside may mean that the light guide plate may be manufactured.

Compared to the frame of the embodiment, the frame for a lighting device according to another embodiment of the present invention, the LED insertion groove is further formed on the end surface of the inner protrusion. In the LED insertion groove, a peripheral LED of the printed circuit board is inserted to emit light into the inside of the frame.

Reflective material is formed on all surfaces of the frame except for the lower surface of the LED insertion groove and the expansion body formed on the end surface of the inner protrusion of the frame. The reflective material may be formed by a coating method. Light emitted from the peripheral LED passes through the inside of the frame and exits to the lower side of the extension body.

Hereinafter, the installation of a lighting device having a frame according to the present invention on the ceiling will be described.

Referring to the drawings, the square-shaped diffusion plate is fitted to the groove formed in the lower side of the main body of the frame. The diffuser plate is a flexible material and can be easily combined by a worker.

Subsequently, the printed circuit board on which the LED is mounted is positioned on the upper surface of the inner protrusion, and is coupled to each other using a screw.

As such, the lighting device in which the body, the diffusion plate and the printed circuit board are integrally fixed is fixed to a panel provided in the ceiling of the facility.

On the ceiling of the facility where the lighting device is installed, the panel support frame is partitioned horizontally and vertically in a matrix shape. The lighting device is embedded in the rectangular installation area thus partitioned. More specifically, at least one panel is attached to the panel support frame, respectively. The panel is removed from the panel where the lighting device is installed, and only one installation area is provided to the operator.

Referring to FIG. 4, the recessed portion of the coupling portion of the frame and the end of the finishing protrusion are in surface contact with the lower side of the panel P provided below the panel support frame PM. At this time, use a screw provided separately to fix the screw in the coupling groove. In the present invention, the installation of the lighting device by screw coupling, but the embodiment, it is also possible to install the lighting device via the T-bar.

In the present invention, a lighting device including a rectangular frame and a rectangular diffuser plate is used as an embodiment, but various shapes such as a circle and a polygon can be formed. Although the frame and the diffuser plate form a shape of various shapes such as a circle and a polygon, the coupling portion of the frame may be configured in a shape defined by the installation area.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the present invention is not limited to the disclosed exemplary embodiments, but various changes and modifications may be made by those skilled in the art without departing from the scope of the present invention.
