Description

A lighting device using LED}

[0001] The present invention relates to an LED lighting lamp, and more particularly, to an LED lighting lamp that can enhance a lightness by reducing a shading section and provide a decorative effect by giving a point to a specific area and having a beautiful appearance.

In general, LEDs have longer lifespan and lower power consumption than fluorescent lamps, and they do not contain harmful substances such as mercury or lead. They are harmless to the human body and are environmentally friendly. It is widely used.

When the LED is used as an illumination light, a mounting substrate on which an LED is mounted on a ceiling or a wall mounted on the wall, and a converter for lighting and controlling the mounting substrate are mounted, and a light emitting cover is attached to the housing to diffuse the LED light.

FIG. 1 shows an example of a conventional LED lighting fixture. The LED lighting fixture is installed in a ceiling 1 and has a converter mounting portion 3 and a plurality of LED mounting portions 4 formed on a bottom surface thereof, A pair of mounting substrates 6 mounted on LED mounting portions 4 of the housing 2 and having a plurality of LEDs 7 mounted thereon and a pair of mounting substrates 6 mounted between the LED mounting portions 4 A plurality of light projecting covers 9a mounted on the lower surface of the LED mounting portion 4 of the housing 2 and a plurality of projectors 9a mounted on the lower surface of the converter mounting portion 3 to be connected to the converters 8 And an opaque cover 9b for concealing the opaque cover 9b. At this time, one end of the light-transmitting cover 9a and the end of the opaque cover 9b are directly or indirectly coupled to the partition 5 of the housing 2.

However, in the conventional LED lighting lamp as described above, illumination is performed through the light-transmitting cover 9a only at the LED mounting portion 4 and light is not illuminated at all by the opaque cover 9b and the partition 5 in the converter mounting portion 3 There is a problem that the overall illuminance is lowered due to the shaded section.

The objects, features and advantages of the present invention will become more apparent from the following detailed description. Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 2 is an exploded perspective view showing an LED lighting lamp according to a preferred embodiment of the present invention, and FIG. 3 is a side sectional view of the installed state of the LED lighting lamp.

As shown in the figure, the LED illumination lamp according to an embodiment of the present invention includes a body 10 installed on a ceiling 1 or a wall and having an LED 41 and a converter 70, And includes a light-transmitting cover 50 and an auxiliary cover 60 which cover the light-

The body 10 includes a central mounting bracket 20 and a plurality of LED mounting portions 30 extending in a row, a radial or a cross shape at a side of the mounting bracket portion 20, And a side wall 25 protruding downward to partition the LED mounting portion 30.

Although the side wall 25 is integrally protruded from the mounting bracket portion 20 and the mounting bracket portion 20 and the LED mounting portion 30 are formed separately from each other in the illustrated embodiment, The bracket portion 20 and the LED mounting portion 30 may be integrally formed.

Preferably, the mounting bracket 20 is injection-molded with a synthetic resin to reduce the weight of the entire lighting lamp. A converter accommodating groove 21 is formed in the center of the lower surface of the mounting bracket 20 for accommodating the converter 70. The converter accommodating groove 21 is concealed by the cover member 22. [ A plurality of through holes 23 through which screws 2 to be fixed to the ceiling 1 and the wall are passed and a fitting hole 24 to which the auxiliary cover 60 is coupled are formed at the periphery of the converter accommodating recess 21, As shown in FIG.

Semicircular side walls 25 are downwardly protruded on four cross-shaped side surfaces of the mounting bracket portion 20 and bent edges 26 are formed on the edges of the side walls 25 to bend outward. A through hole 27 is passed through the side wall 25 in the forward and backward directions.

The plurality of LED mounting portions 30 are extruded into aluminum for effective heat dissipation of the LEDs 41 and are coupled to four sides of the mounting bracket portion 20 by unshown brackets. In addition, a strip-shaped PCB 40 having a plurality of LEDs 41 mounted thereon is mounted on the lower surface of the LED mounting portion 30. [

The light-transmissive cover 50 has a downwardly convex shape by curving the plate, and covers the lower surface of the LED-mounting portion 30 to diffuse the light of the LED 41. In the illustrated embodiment, the cross section is curved in a semicircular shape so that one end thereof is caught by the bent end 26 of the side wall 25 of the mounting bracket portion 20 of the body 10. At this time, the other end of the light-transmitting cover 50 is fixed to the other end of the LED mounting portion 30 by the fixing means 31 and is closed.

The auxiliary cover 60 is convex downward and covers the lower surface of the mounting bracket 20 of the body 10, and a transparent portion 61 is formed at the center. Preferably, the transparent portion 61 is made of various colors different from the transparent cover 50. The auxiliary cover 60 is provided with an elastic coupling protrusion 62 which is detachably coupled to the fitting hole 24 of the mounting bracket 20 at the periphery of the transparent portion 61.

In the LED illumination lamp according to the embodiment of the present invention, most of the light emitted from the LED 41 is diffused through the light-transmissive cover 50, but a part of the light is transmitted through the side wall 25 of the body 10 Through the through hole 27 of the mounting bracket portion 20. Accordingly, since the introduced light is illuminated to the outside through the transparent portion 61 of the auxiliary cover 60, the shaded region can be reduced as compared with the conventional method, and the illuminance can be further increased.

At this time, the center portion of the LED illumination light is illuminated with a low-illuminance light, so that it can give a point to a specific region, which can give an appearance and a decorative effect. In particular, when the transparent portion 61 is changed in various colors, light of various colors is lightly illuminated, so that the beauty and decoration effect can be further enhanced.

4 is a side sectional view of an LED lighting lamp according to another embodiment of the present invention in an installed state. The light guide plate 80 is provided on the lower surface of the cover member 22 covering the converter housing groove 21 of the mounting bracket 20 and the light guide plate 80 is fixed to the light- (61). The LED light introduced into the mounting bracket portion 20 through the through hole 27 of the side wall 25 of the body 10 is more concentrated by the light guide plate 80 to the light projecting portion 61 , It is possible to further enhance the illuminance of the central portion of the LED lighting lamp, thereby effectively reducing the shading section.

5 is a perspective view illustrating an LED lighting lamp according to another embodiment of the present invention. As shown in the figure, in the present embodiment, a bar-shaped LED lighting lamp formed integrally with a rod-like body constituting the LED mounting portion 30 on both sides of a body 10 in which aluminum is extruded by a rod- 20 are formed in a '∪' shape projected by a synthetic resin, and are installed at a central portion of the body 10 to divide the two LED mounting portions 30. At this time, side walls 25 are formed on both sides of the mounting bracket portion 20, and the internal structure and operation effects are the same as in the previous embodiment.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
