Description

{CEILING MOUNTING LIGHTING DEVICE}

The present invention relates to a ceiling mount type illuminator, and more particularly to a ceiling mount type illuminator that adjusts the directionality of light emitted into a room after installation of the illuminator through a rotating plate rotatably coupled to a stationary plate attached to the ceiling To a ceiling mount type illuminating device capable of maximizing an aesthetic lighting effect through a light emitting portion which selectively emits light toward the outer peripheral portion side and the center portion side of the lighting device while improving workability and aesthetic effect.

LED (Light Emitting Diode) illumination is an illumination device using an LED that emits light having a predetermined wavelength by electric power supply. Currently, LEDs are being used in various fields such as signs for advertisement, indoor and outdoor interiors, etc. in place of conventional illumination lamps with an increase in light emitting lifetime. In particular, many LED lighting apparatuses for replacing fluorescent lamps, which are widely used as indoor lighting, have been developed. However, the LED lighting apparatus currently being used has limitations in various aspects.

Fig. 1 is a reference view for conventional edge illumination, and Fig. 2 is a sectional view along a-a 'in Fig.

Referring to FIG. 1, it is impossible to adjust the directionality of light once installed, regardless of whether it is a ceiling mount type or a pendant type. Conventionally, when the ceiling mount type LED edge light is mounted on the ceiling, It is necessary to fix the lighting position to the ceiling in advance after fixing the mounting position of the lighting in consideration of the shape of the ceiling and the space, and it is impossible to adjust the direction of the light once fixed to the ceiling. In particular, when the outer circumferential surface of the illumination is formed in a polygonal shape having a non-circular shape, the directionality of light is not uniform, so it is necessary to adjust an installation angle and the like according to the rotation of the illumination. However, Resulting in inconvenience of use.

In addition, the conventional LED edge illumination generally has a limitation in utilization of the light emitted from the light source part d in a radial pattern only to the outer periphery side of the illumination device, and the outer periphery side and the center side The center-side illumination is generally a straight-down type instead of the edge type. As a result, the thickness of the illumination becomes thick as a whole, resulting in a loss of aesthetics and a problem of glare.

In addition, in the conventional LED edge illumination, the connector c, which is connected to the electric wire, is located between the light source part d and the heat sink b, and the circuit board and the light source, which are in contact with the connector c, are in contact with the heat sink b It is not possible to achieve an optimized heat dissipation effect by the heat dissipating plate (b), and there is a problem that the light source portion (d) is damaged by heat due to the occurrence of a weak heat dissipation portion.

Another problem is that a protector (d) is provided on the outer circumferential surface of the light guide plate (e) in combination with the light guide plate (e) or the like for fixing the protector (d) There was a problem in the stability of the LED illumination.

Patent No. 10-1412134 discloses a slender pendant lighting device that separates a light source and a power source to attach the power source to the ceiling and suspends the light source and the light guide plate in a pendent form so as to make the shape of the light illumination slimmer, It is a slender pendant lighting device that can be safely suspended from the ceiling.

The ceiling mount type lighting apparatus includes a fixed plate 1 mounted on a ceiling, A light emitting portion 5 coupled to the rotary plate 3 and selectively emitting light toward the center portion side of the outer peripheral portion side of the illumination device, The lighting device can adjust the directionality of the light even after the ceiling mount of the lighting device is adjusted so as to harmonize with the space in the room where the lighting device is installed and to improve the workability and to selectively provide light to the outer peripheral side and the center side of the lighting device To a ceiling mount type illumination device capable of emitting an aesthetic lighting effect.

3 to 6, the fixing plate 1 is attached to the ceiling for installing the lighting device in the room. The shape of the fixing plate 1 is not limited. However, in the following embodiments, the fixing plate 1 is formed in a disc shape, and the examples do not limit the scope of the present invention.

However, this is merely an example, and the fixing plate 1 and the rotary plate 3 can be coupled to each other using various known means. Although there is no limitation on the number of the coupling means 13, the following description will be made on the basis that three coupling means 13 are formed. To this end, the coupling means 13 may include a seating portion 131 and a penetrating portion 133.

7, the seating part 131 is formed to extend downward from the lower surface of the fixing plate 1 in a predetermined shape so that the body of the fixing plate 1 and a rotating plate 3, which will be described later, So as to be coupled. That is, the lower end of the seat portion 131 is formed to have a size suitable for being seated on the upper surface of the rotary plate 3 without being inserted into the coupling means receiving hole 35, which will be described later. Therefore, since the body portion of the fixed plate 1 and the body of the rotating plate 3 can be separated from each other by the seating portion 131, the rotation of the rotating plate 3 can be easily performed without friction with the fixed plate 1 (See FIG. 5).

The penetrating part 133 is formed by extending downward from the lower end of the seat part 131 in a cylindrical shape to connect the fixed plate 1 and the rotary plate 3 with each other.

As described above, it is impossible to adjust the directionality of light according to the rotation of the illumination device after the illumination device is mounted on the ceiling. Particularly, there is a problem in that the lighting device is formed in a non-circular shape so that when the directionality of the light is not uniform, the lighting device needs to be released from the ceiling again and reattached. On the other hand, in the lighting apparatus according to the embodiment of the present invention, even after the lighting apparatus is installed on the ceiling, the rotation plate 3 and the light emitting unit 5 coupled to the rotation plate 3 rotate together at a predetermined angle There is an advantage that the directionality of light can be controlled.
