Description

[0001] The present invention relates to an LED ceiling lights,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an LED ceiling fixedly mounted on a ceiling of a room such as a home or an office, and more particularly, to a heat radiating plate having an LED light source plate and a cover member using a cover frame, Since the members are mutually coupled and fixed to each other by the pressing force of the cover frame, it is very easy to assemble and manufacture the ceiling and the like, and the separation and reassembly of the cover member or the LED light source plate is very quick and easy And the LED ceiling that can be made.

Generally, in a home such as a single-family house or a multi-family house, an illumination lamp for illuminating the interior is essentially installed, and a lighting lamp for securing excellent interior illumination in an office, an office building, It should be.

Most of these lighting fixtures are fixedly installed or installed in the ceiling of the room. Depending on the installation method, they will be divided into ceiling fixture and ceiling fixture, and they will be divided into ceiling fixture or ceiling fixture depending on the installation type. A fluorescent lamp, an incandescent lamp and an LED according to the type of the lamp built in the lamp.

In this case, a lamp, a socket, a stabilizer, and the like are installed inside a fixed body formed by bending a metal plate in a circular or rectangular shape most commonly, and the bottom of the fixed body is provided with a milky white synthetic resin Or an illumination cover made of glass. Accordingly, when power is applied to the lamp coupled to the fixing body, the lighting light of the lamp is transmitted and diffused through the lower lighting cover, thereby illuminating the entire room.

In addition, in the case of ceiling hanging or the like as described above, it is composed of a fixing plate which is installed in close contact with the ceiling front surface and a single or a plurality of lighting lamps which are fixedly installed and fixed to the indoor side by using wires or the like from the fixing plate. When the lamp or the LED located inside the cover body is turned on, the lighting light is irradiated toward the room through the lower part of the opened cover body . Such ceiling hangers are not used as lighting means for a large area but are used for brightly illuminating a limited area of a local area such as a dining table.

However, the above general ceiling light fixture maintains the basic structure of the fixed body and the light cover for a long time, and almost all of the ceiling light fixtures are similar in shape and design, so that they are tender and have little interior effect.

As a result, the structure of the ceiling light for the near future is being improved, or the design or the form is being changed. It is not merely a combination of the fixed body and the light cover, but a more simplified fixing And a combination structure of multi-divided illumination covers for the main body, and so on.

In addition, most of the illuminating lamps function to illuminate the room through the lower side of the fixed body, and the illuminating light of the inner lamp is diffused through the lower surface of the illuminating lamp. As for the recent improved illuminating lamp, So that the light of the inner lamp is transmitted through the decorative plate to improve the decorative property of the illumination lamp.

That is, through the side plate of the fixed body, the penetrating portion is formed with a transmissive decorative plate such as milky white acrylic from the inside of the fixing body, and when the internal lamp is lit, the decorative plate is indirectly lit, It is producing a lighting effect.

However, since the ceiling lamp having the above-described decorative lighting unit is required to pass through the side plate to which the decorative plate is attached, the appearance is unfavorable. In addition, the user can use the decorative plate illuminated by the translucent decorative plate attached to the inner surface of the side plate, It can be predicted that it will be done. Therefore, it is not possible to expect freshness and differentiation in comparison with the conventional illumination lamp because the curiosity is induced or the interest in the lighting state is greatly reduced.

In addition, the ceiling light of various structures as described above has a problem that the economical efficiency is not high because the decorative or the beauty is not so high as compared with the high production cost.

In addition, the conventional ceiling light fixture has a very complicated and various structure for combining and separating the illumination cover for the fixture main body, which is very inconvenient to use. In the case of such an illumination cover, And the lighting cover must be connected to the fixed body after the fixation of the fixture body in the process of installing the lighting fixture. Therefore, it is necessary to perform a conventional method of combining and separating The ceiling lights are not only inconvenient to use, but also cost a lot of production costs, resulting in extremely low productivity and productivity.

That is, in the case of the rotary lever structure, the lever is exposed from the room, so that the appearance is not simple or beautiful. Also, the pressing structure by the spring elastic sphere has a disadvantage in that the elastic sphere is entirely exposed to the room. The structure of the structure is exposed to the inside of the room, and the working time due to assembly and disassembly is prolonged.

In addition, the conventional coupling means as described above for the illumination cover is inconvenient to use both hands in the process of reassembling or mounting the illumination cover. In a state in which the illumination cover is supported from the bottom by one hand It is necessary to operate the binding means of each other by using the other hand and to fix the lighting cover to the fixing body so that the operation is very cumbersome and difficult and the lighting cover is dropped to the floor and is damaged or injured Are frequently occurring.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems described above, and it is an object of the present invention to provide a liquid crystal display device and a liquid crystal display device, which are formed by combining a cover member made of a translucent material and a heat sink having upper and lower LED light source plates, , The heat radiating plate and the cover member are structured so as to be firmly engaged and fixed to each other through the elastic force of the pressing force of the cover frame without any separate fastening means,

It is very easy and quick to assemble and manufacture various types of lighting lamps such as a ceiling direct lighting lamp, a ceiling lighting lamp or a wall, etc., and it is easy to separate and cover the cover member and the LED light source plate, The present invention is also directed to a press-clamped LED ceiling having a simple fastening structure that greatly simplifies aspects of maintenance.

The cover frame 10 has a locking protrusion 11 protruded on the inner side and an insertion groove 12 formed on the lower side in a downwardly opened manner. Are formed in the receiving groove portions 13 and 13 '.

The heat-radiating plate 20 is extruded and produced by using a heat-dissipating material such as aluminum. The heat-radiating plate 20 is formed with outwardly curved planar portions 21 and 21 ' .

The LED light source plate 40 is closely fixed to the bottom surface of the heat sink 20 so that the LED light source plate 40 having a plurality of LEDs soldered toward the room is mounted on the bottom surface of the heat sink 20 They can be firmly fixed to each other by using fastening bolts or the like in a state of close contact.

The cover member 30 is a semitransparent material having an open upper portion. The cover member 30 hides the LED light source plate 40 from the indoor side, and diffuses the light emitted from the LED light source plate 40 evenly, So that the entire room can be illuminated evenly.

The heat sink plate 20 having the LED light source plate 40 is fixedly coupled to the cover frame 10 from above and the cover member 30 is inserted and fixed from the lower side. So that a firm engagement state can be maintained by the mutual elastic force due to the pressurization without the fixing means.

5, the heat-radiating plate 20 is formed with the protruding portions 21 and 21 'on both sides of the bottom, so that the heat-radiating plate 20 is placed on the upper side of the cover frame 10, The pressing portions 21 and 21 'interfere with the engaging jaws 11 of the cover frame 10 to cause a momentary deformation inward and then return to the original positions while passing the engaging jaws 11, And a fixing force.

6, the cover member 30 is pushed up from the lower side of the cover frame 10 with an artificial force. The cover member 30 is formed in the insertion groove portion 12 of the cover frame 10 And an elongated rod-like rod 50 'or 50' is placed in the receiving groove 13 or 13 '. The rod 50' or 50 ' As shown in Fig.

Accordingly, when the cover member 30 is pushed upwards, the tip of the cover member 30 will interfere with the tacking rods 50 and 50 ', and the tacking rods 50 and 50' Is temporarily expanded due to the deformation. By this extension, the cover member 30 can be completely inserted into the inner deep portion of the insertion groove portion 12, and the elastic rods 50 and 50 ' And is brought into close contact with the side surface of the cover member 30 to provide a constant pressing force. Therefore, the cover member 30 is firmly fixed to the cover frame 10 by the pressing force of the tumblers 50 and 50 '.

In this case, the inner width of the insertion groove 12 should be wider than the width of the insertion end, which is the tip of the cover 30, and the inner side of the insertion groove 12, When the cover member 30 is inserted, the interference with the rod rods 50 and 50 'is generated first, and the continuous pressing force is applied to the rod rods 50 and 50' So that the end portion of the cover member 20 can be inserted deeply into the inside of the insertion groove portion 12. In addition,

Although it has been described that the heat radiating plate 20 is coupled to the cover frame 10 from above and the cover member 30 is engaged from the lower side, if necessary, the cover frame 10 may be turned upside down to cover the cover member 30 It may be possible to fix the heat sink 20 by pressing downward and fixing the heat sink 20 again by pressing them down again and work in the order and direction desired by the operator without stipulating the operation mode, method and order.

Further, the rods 50 and 50 'may be made of a metal rod or made of synthetic resin, and may be made of rubber or silicone if necessary, The protruding portion may integrally protrude from the inner side of the protruding portion 12 so as to perform the role of the rods 50 and 50 '.

In the present invention, in order to stably accommodate the tacking rods 50 and 50 'in the process of placing the tacking rods 50 and 50' in the receiving troughs 13 and 13 ' As shown in FIG. 7, a trench 14 is formed on the inner surface of the receiving groove 13 or 13 'and an adhesive 15 is applied to the trench 14 to prevent the trench 13' from becoming too wide. When the rod 50 or 50 'is placed in the receiving groove 13 or 13' in the state of being injected or applied, the solid rod 50 'or 50' Can be achieved.

At this time, the adhesive may be directly applied to the inner surfaces of the receiving grooves 13 and 13 ', but adhesive bonding using the wire grooves 14 may be more effective in view of problems such as flowing of the liquid adhesive, It is possible to minimize the inner surface area of the receiving grooves 13 and 13 'due to adhesion and fixing of the tacking rods 50 and 50' by the troughs 14 and to form the receiving grooves 13 and 13 ' It is possible to prevent the irradiation range of the LED light source plate 40 from being lost due to an increase in the cross section of the cover frame 10. [

8 shows another embodiment for securing a stable supporting force of the elastic rods 50 and 50 'while increasing the fixing force to the cover member 30 as shown in FIG. The tongue 16 and the receiving tongues 13 and 13 'protrude in the horizontal direction or the upward tilted form toward the insertion groove 12 so that the tongue bar 50 ') Can be inserted stably.

In this state, when the cover member 30 is pressed to the inside of the insertion groove 12, the end surface of the cover member 30 is guided to the insertion groove 12 and pushes the elastic parts 21 and 21 ' And the bent portion 16 is bent downward while interfering with the folded portion 16.

Since the bent portion 16 bent in this manner will have a force for restoring the original shape continuously, the surface of the cover member 30 is strongly pressed and the fixing force to the cover member 30 can be further improved. This allows the cover member 30 to maintain a strong and firm fixed state with respect to the cover frame 10 due to the pressing by the rods 50 and 50 'and the pressing by the bent portion 16 .

Therefore, the LED ceiling of the present invention can quickly and easily manufacture the illumination lamp through its own shape and the tongue structure without any separate fastening and fixing means. The high temperature at the time of lighting, which is generated in the LED light source plate 40, It is possible to prevent the efficiency of the LED light source plate 40 from being lowered due to rapid heat dissipation through the heat sink 20.

It may be directly fixed to the ceiling using the heat sink 20, or may be installed in the form of a wire or the like connected to the heat sink 20 to hang.

Also, when the LED light source plate 40 located inside is required to be inspected or replaced, an artificial force is applied to detach the cover member 30 from the cover frame 10 to completely expose the LED light source plate 40 It is very easy to install and maintain the lighting fixtures and is very remarkable in terms of maintenance.
