The embedding lighting section 110 is a member embedded in the ceiling 200 and functioning as an illumination.

Here, the embedding lighting section 110 may include, for example, a housing section 111, a light emitting section 112, and a window section 113. The housing part 111 is embedded in the ceiling 200 and functions as a main body and may have a receiving part 114 therein. The light emitting portion 112 can be received in the receiving portion 114 of the housing portion 111 and the housing portion 111 functions as a reflector so that the light from the light emitting portion 112 can be effectively radiated to the outside can do. Meanwhile, the housing part 111 may include a separate reflection shade, and the reflection shade may have a shape of, for example, a collimated light and effectively reflect the light of the light emitting part 112 downward.

The light emitting unit 112 may include a power supply unit provided on the printed circuit board, for example, a rectifier smoothing circuit for rectifying and converting an AC voltage into a DC output voltage, a DC-DC converter, and a DC- An AC / DC converter such as a high-frequency transformer, an output smoothing circuit, etc., and can supply power to a light emitting element such as an LED by changing an AC power source to a DC power source.

On the other hand, the window 113 may be located on the opposite side of the housing part 111 with respect to the light emitting part 112 and may protect the light emitting part 112 from the outside. Accordingly, the light emitting portion 112 can be protected without being exposed to the outside by the housing portion 111 and the window portion 113. The window 113 may be exposed to the outside of the ceiling 200 and may be parallel to the ceiling 200 or partially protruded to the outside of the ceiling 200. In addition, the window 113 may be made of transparent or semitransparent material so as to effectively transmit the light of the light emitting unit 112 to the outside, and may have light diffusion characteristics, for example, glass or plastic. Such a window 113 can be used for the purpose of improving glare and uneven illumination while preventing the light of the light emitting portion 112 from being excessively focused. However, the present invention is not limited to this, and the window 113 may be provided with a frame having an opening and a transparent or translucent window provided in the opening.

Fig. 3 is a block diagram for explaining the embedding lamp 100 having the dimming function shown in Fig. Hereinafter, the dimming unit 120 of the embedding lamp 100 having the dimming function according to the present embodiment will be described in detail with reference to FIG.

As shown in FIGS. 1 to 3, at least a part of the dimming unit 120 may be installed in the window 113 of the buried lighting unit 110 and exposed to the outside. For example, the dimming unit 120 may include a dimming input unit 121 for receiving a dimming level value from a user and a dimming control unit 122 for controlling the illuminance of the light emitting unit 112 according to a dimming level value input to the dimming input unit 121 At least some of the dimming input unit 121 may be installed in the window 113 and exposed to the outside.

This is important in relation to the features of the present invention. The buried lighting part 110 is embedded in the ceiling 200 and is not exposed to the outside of the ceiling 200 except for a part like the window part 113. Therefore, if the dimming input unit 121 is installed in the buried area, for example, the housing unit 111 or the light emitting unit 112, the user can easily adjust the illuminance of the light emitting unit 112 only when the buried light 100 is installed for the first time. Can be adjusted. Of course, the dimming input unit 121 may be operated after the installation, but in such a case, the ceiling 200 is torn out to expose the housing unit 111 and the light emitting unit 112 to the outside, . However, since the dimming input unit 121 is installed in the window 113 and is exposed to the outside of the ceiling 200, the embedding lamp 100 having the dimming function according to the present embodiment is not limited to the case of installing the embedding lamp 100 for the first time, The illuminance of the light emitting unit 112 can be easily adjusted by operating the dimming input unit 121 exposed to the outside. The distance between the dimming input section 121 and the light emitting section 112 can be reduced by providing the dimming input section 121 on the window section 113. This makes it possible to shorten the electrical path compared to the case where the dimming input section 121 is installed on the wall, To provide convenience.

Here, the dimming level value input to the dimming input unit 121 may be represented by, for example, a luminance (Lx) or a relative value with respect to the reference illuminance value by 100%, 75%, 50%, 25% Can be. The dimming control unit 122 controls the power supply unit power supply of the light emitting unit 112 according to the dimming level value input to the dimming input unit 121 and supplies the power to the light emitting unit 112 using, The brightness of the light emitting portion 112 can be controlled by adjusting the value of the voltage or the current or by using a PWM (Pulse Width Modulation) signal known in the art. The dimming control unit 122 may be installed in the window 113 together with the dimming input unit 121 and may be exposed to the outside or may be located inside the window 113 and connected to the dimming input unit 121 through a separate lead .

The dimming level value may be changed according to the direction of the first switch 121a and the second switch 121b and the dimming control unit 122 may transmit the dimming level value to the light emitting unit 112 according to the four different dimming level values. The illuminance of the light emitting portion 112 can be adjusted by varying the current or voltage.

For example, when both the first switch 121a and the second switch 121b face the first direction (Fig. 4A), the first switch 121a is turned off The light emitting portion 112 is illuminated with the illuminance corresponding to 75% as compared with the illuminance when the second switch 121b faces the second direction (Fig. 4 (b)), The first switch 121a is directed to the second direction and the second switch 121b is directed to the first direction (Fig. 4 (c)), compared with the illuminance of Fig. 4 (a) The light emitting portion 112 can emit light with an illuminance corresponding to 50%. When the first switch 121a and the second switch 121b are all directed in the second direction (Fig. 4 (d)), compared with the illuminance in Fig. 4 (a) The light source 112 can emit light. However, the operations of the first switch 121a and the second switch 121b are illustrative and those skilled in the art will readily be able to implement embodiments having the same technical idea using such technical ideas. It is a technical idea included in the invention.

The user can easily change the illuminance of the light emitting portion 112 while moving the first switch 121a and the second switch 121b used as the dimming input portion 121 and thus can be very convenient.

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 the embedding and the like having a dimming function according to the present invention are not limited thereto. It will be apparent that modifications and improvements can be made by those skilled in the art.
