Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a ceiling light fixture for ceiling mounting,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling mount line light fixture in which a diffuse light plate is assembled in a fixed frame, And a line lighting lamp for ceiling mounting which is improved in stability by improving a prefabricated structure so as not to fall off from the frame without depending on a disassembling operation.

In general, stores that handle various products such as department stores, large stores, and small marts are equipped with light fixtures to enhance the display effect of various products displayed on display shelves and display shelves, and the light fixtures installed in the stores are provided with shelf space And on the ceiling as a means to secure a wide range of passageways for customers.

Also, when a ceiling lamp is to be installed, a large number of lighting lamps are installed at regular intervals to illuminate the interior of the store.

However, if a large number of lighting fixtures are to be installed at regular intervals on the ceiling of a store, a hanger structure such as an anchor that can suspend the respective lights should be installed, and a wire for supplying power to each lighting fixture should be connected like a web In addition, the ceiling structure of the store becomes very complicated due to the large number of light fixtures installed at a certain interval on the ceiling of the store and the wires connecting them, It is pointed out that it is difficult for the worker to replace the lighting lamp installed in the ceiling by using a ladder and the like and the risk is followed.

In order to solve the above-described drawbacks of the related art, there is a tendency recently to install line lights on the ceiling in shops handling various goods.

Therefore, the applicant of the present invention has proposed a line lighting lamp for ceiling installation of Patent Application No. 2015-29539, which has been commercialized and provided on the market.

10, a frame 200 such as a line lighting lamp is installed in a suspended state on an anchor 110 installed at regular intervals in an M bar 100 fixedly installed on a ceiling of a store And a plurality of LEDs 300 for emitting illumination light are installed to be interchangeable in the upper part of the frame 200. The upper surface of the frame 200 is closed and the upper surface of each of the side walls 210 A locking protrusion 230 protrudes from the inner surface of the locking end 220 formed at the lower end of the LED 300 and light is emitted from the LED 300 to the locking ends 220 formed at the lower end of the both side walls 210. [ And a diffusion illumination plate 400 for illuminating the interior of the room 200 is installed on both sides of the diffusion illumination plate 400 in the width direction. At the bottom of each The both side resilient pieces 410 having the inclined protrusions 411 and the engagement grooves 412 formed to face each other symmetrically so as to be able to be elastically bonded to the protrusions 230 formed on the inner surface of the formed locking end 220 Structure.

The prior art constructed as described above can be installed so that neighboring line lights are parallel to each other according to the characteristics of the store, and that the line lights can be installed at right angles, However, in the above-described prior art, when a certain period of time has elapsed, a line lighting lamp installed on a ceiling of a store is used to illuminate the ceiling of a store 200, It has been found that there is a danger that the diffusion illumination plate 400 which is assembled in a state of being elastically hooked on the engagement end 220 formed at the lower end may fall down. The greater the weight, the greater the probability that the frame 200 is separated from the lower ends of both side walls 210 It was found that there is a risk that would be.

This is because the diffusion illumination plate 400 is formed of a synthetic resin (for example, acrylic resin) containing a diffusing agent for diffusing blue light and is formed to a thickness of 1 mm or more, so that the diffusion illumination plate 400 itself has a considerably heavy weight And the frame 200 such as a line illumination where the diffusion illumination plate 400 is installed is extrusion-molded from aluminum. In view of the fact that both side walls 210 are formed to have a thin thickness of about 1 mm or so, (See the imaginary line portion shown in FIG. 10) and that the diffused illumination plate 400 is also capable of being bent at the room temperature of the store (See the imaginary line portion shown in FIG. 10), and the like, the diffused illumination lamp 400 may be provided with a light source Because it appears to be a problem that the frame 200 of the both side wall surfaces 210 also cause the risk of fall is separated from each bottom of a situation which is a great need to improve the problem urgently.
