Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an LED frame,

[0001] The present invention relates to an LED frame which is used in combination with a wiring duct integrated luminaire. More particularly, the present invention relates to an LED frame which is installed in a large indoor space and which is superior in luminous efficiency to fluorescent light, It is possible to use the lighting device in combination with the integrated lighting device, and at the same time, it is possible to further reduce the time cost for construction and maintenance by extremely easy detachment of the lighting device, And to use the half of the LED illumination according to need, so that the power saving effect can be achieved.

       Modularized raceway lighting is generally installed for large-scale indoor lighting systems because of the large number of lighting systems that must be installed collectively. The conventional raceway module goes through a five-step process consisting of installing a hanger that can put the lighting system on the ceiling, cutting the site, installing the wiring body, installing the luminaire, and inspecting the wiring and wiring. This has complicated processes, time consuming and labor cost. In addition, there is also a problem of inefficiency of installation space due to the loss of electrical equipment due to leakage of water and separation of wiring modules and lighting devices when rain is generated during the construction period. In particular, Frequently, the height of a vehicle that can be used in a parking lot is severely limited.

       In order to solve such a problem, the present applicant has previously proposed a method of manufacturing a lighting system through a plurality of applications including an application number 10-2005-0093460 wiring duct, an application number 10-2005-0093461 duct connection apparatus, an application number 10-2004-0086297, And a wiring duct integrated luminaire for a connection installation. In order to compensate for the disadvantages of the conventional raceways, the luminaire device can be assembled directly to the lower part of the wiring body without a separate connecting clip or the like, and the wiring between the wiring body modules is electrically connected with the connector and mechanically coupled with the coupling This eliminates the need for a process such as field cutting and installation of a separate luminaire, thereby eliminating the troublesome process of the process. In addition, by taking the watertight structure in the upward direction, the problem of facility loss due to leakage in the rain is eliminated at the time of construction, and the volume is minimized by integrating the lighting device, thereby making it possible to utilize more free space.

       However, in order to maximize the merits of the new method, it is necessary to minimize the volume of the lighting device, and to simplify the construction and improve the form of the module for easier maintenance .

       Similar techniques for solving the problem of the conventional raceway type indoor lighting system have been disclosed in recent related technologies such as the registration utility model 20-0462138, the registration utility model 20-0333042, the patent invention 10-1005279, and the patent invention 10-0933489. . These techniques are effective in eliminating the hassle of the process, which is a problem of the conventional raceway method. However, there is a problem in that there is no wiring storage structure or is too narrow, and the number of components is large, so that the assembling process and manufacturing cost are expensive, or replacement and removal of parts for maintenance are difficult.

       In recent years, LEDs have been widely used as lighting devices in place of fluorescent lamps and incandescent lamps. Since LEDs are directly converted into optical energy, the LEDs have advantages in terms of light efficiency, power consumption and life span, There is an advantage that it can be selectively projected. In this regard, it will be necessary to manufacture luminaires that can utilize the optimal space while enhancing the efficiency of the lighting by adopting the LED in the wiring duct integrated luminaire. However, in addition to the conventional raceway method, a new technology such as a wiring duct integrated lighting device also requires the installation of a fluorescent lamp, so it is urgent to disseminate the technology related to the lighting module using the LED.

Accordingly, it is possible to easily attach and detach but also to be stably engaged, thereby reducing the time and cost required for installation and maintenance. Also, it is necessary to install the entire lighting system with only a minimum number of parts, It is possible to accommodate space other than communication and other electric wiring, and it is possible to solve the simultaneous request to be able to partly turn off the power as needed while improving the power saving and optical efficiency by adopting the high efficiency LED module New technologies are required.

The present invention relates to a wiring duct integrated lighting device which is easy to construct and maintain and which has a light-efficient and power-efficient LED, but adopts a structure that enables more effective space utilization and reduces power consumption And to provide an LED frame used in a wiring duct integrated type lighting apparatus.

       An LED frame 10 having a longitudinally elongated cross section is convex upward and a center of the convex surface is formed as a horizontal plane D and the LED frame 10 takes a shape vertically downward from both left and right ends 12 of the frame 10 includes an LED substrate mounting part for connecting the LED substrate 60 in parallel under the horizontal surface D of the frame 10 and a diffusion plate 40 at both left and right ends of the frame 11 And a wiring duct coupling portion 13 coupled to the wiring duct on an upper outer surface adjacent to the diffusion plate coupling portion 12, wherein the LED frame 10 is an integrated type wiring duct And is used for a luminaire.

       The coupling between the LED substrate 60 and the LED frame is achieved by a method in which the projections 11 projecting downward from the horizontal surface of the LED substrate are bent in the lateral direction of the LED substrate, The LED substrate may be coupled to the LED substrate in a manner that the LED substrate is coupled to the LED substrate by a fastener, or may be coupled with an adhesive.

      The diffusion plate coupling portion 12 is provided with grooves whose opposite sides are opposite to each other at the left and right ends of the frame so that the diffusion plate 40 is coupled in an interference fit or sliding manner, And has a shape corresponding to both left and right ends 21 of the open lower part of the wiring duct frame 20 which is connected to the upper part of the LED frame and is adjacent to the diffusion plate coupling part above the diffusion plate coupling part 12, Or sliding manner.

A separate power supply unit 50 is provided between the LED frame and the wiring duct so that the power supply can be cut off for each of the LED substrates 60 installed in parallel. The distance between the reflector plates on both the left and right sides increases as the reflector 70 moves from the upper part to the lower part between the plate coupling parts 12 or between the LED board mounting part 11 and the diffusion plate coupling part 12, A surface coating is formed on the inner wall of the frame by a metal, a resin, or a composite of metal and resin having a high reflectance, so that the inner wall of the LED frame itself can serve as a reflector.

       The LED frame according to the present invention can be applied to an integrated lighting device having a higher luminous efficiency than that of a wiring duct integrated with a lighting device. Since the shape of the LED frame is completely inserted into the wiring duct, the space occupied by the integrated wiring- At the same time, wiring ducts, lighting, lighting, communication wiring and electrical wiring are accommodated at the same time, thereby achieving the best space efficiency. Accordingly, it is possible to solve the problem of damage to the lighting facility due to the height of the vehicle, which is problematic in the indoor parking lot, while having a simple and simple appearance.

FIG.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is an exploded perspective view of an LED frame of the present invention coupled to a wiring duct. FIG. 2 is a cross-sectional view of the present invention when it is coupled to a wiring duct, and FIG. 3 is an exploded perspective view thereof.
An LED frame used in a wiring duct integrated luminaire of the present invention refers to a rigid structure referred to as symbol 10 in Figs. 1 and 2. As shown in the drawing, the LED frame 10, which is formed long in the longitudinal direction, is convex upward when viewed in a sectional structure, the center of the convex portion is formed in a horizontal plane, Shape. Here, the horizontal plane is a section represented by 'D' in FIG.
In the detailed configuration, an LED substrate mounting portion 11 that is coupled to the LED substrate at the bottom surface of the horizontal plane D, a diffusion plate coupling portion 12 at both left and right ends to be coupled with the diffusion plate, And a duct coupling portion 13.
More preferably, the LED substrate 60 is disposed in parallel with the LED substrate mounting portion 11, and the mounting method is preferably such that the left and right sides of each LED substrate 60 in the width direction are formed as protrusions And the LED substrate is forced or slidingly coupled to the substrate. However, it is also possible that the LED substrate 60 and the LED frame 10 are coupled to each other through a fastener or a double-sided tape or an adhesive.
2, the left and right ends of the LED frame 10 are bent so that their concave portions are opposed to each other, and both ends of the translucent diffusion plate 40 are connected to the LED frame 10, (10) at both left and right ends thereof in a sliding manner. At this time, the shape of the translucent diffusion plate 40 is not limited, but is preferably a planar shape.
This is because the wiring duct 20 to which the LED frame 10 of the present invention is coupled is connected in such a manner that the lower portion thereof is opened and the LED frame 10 is inserted into the lower portion of the wiring duct 20, The space occupied by the luminaire formed by the LED frame 10 and the wiring duct 20 is coincided with the space occupied by the wiring duct 20 so that both the wiring and the lighting device are housed inside the wiring duct 20 In particular, parking lot lighting facilities, which are problematic, can solve the problems of collision due to vehicle height and damage to lighting facilities.
That is, the wiring duct coupling portion 13 is located near the left and right ends of the lower portion of the LED frame, and the corresponding wiring duct coupling portion coupling protrusions 21 at the right and left ends inside the wiring duct 20 are also connected to the wiring ducts 20 And the LED frame 10 is inserted into the wiring duct 20 so that the height of the LED frame 10 can be reduced.
The connection of the wiring duct 20 and the LED frame 10 has a shape in which the left and right ends of the wiring duct 20 have a circular engagement hook shape and form a curved part of a semicircle while coming in. The wiring-duct connecting portion 13 of the connecting portion 13 is coupled in a tight fitting manner.
In general, even when the interference fit method is planned, only the rigidity of the joint is taken into consideration. In addition, the protrusion of the engagement protrusion formed for the interference fit is so great that only the sliding engagement is possible in many cases. In this case, So that it can be easily engaged and dismounted, and at the same time, it is possible to make a strong connection so as to withstand the self-load of the LED frame, (13).
Like the shape of the LED frame 10, the LED substrate 60 is long in the longitudinal direction and is coupled to the LED substrate mounting portion 11 on the bottom of the central horizontal surface D of the LED frame. The LED power supply unit 50 is installed separately for each column in order to independently cut off the power supply to the respective rows, and the installation position of the LED power supply unit 50 is installed separately from the wiring duct and the LED And is positioned between horizontal planes D of the frame.
In order to save power, it is possible to cut off the power for each area by lighting level, but it is more common to adjust the lighting level by time by lowering the overall illumination level rather than powering off the power for each subdivision. In the case where the LED substrate 60 and the LED power supply 50 are simultaneously installed in parallel, only one row is turned on and the two rows are turned off, thereby achieving both the partial illumination and the power saving.
Meanwhile, the inner wall of the LED frame 10 itself may serve as the reflector 70, but a separate reflector 70 may be provided.
If a separate reflector 70 is provided, a means by which the reflector can be combined is needed.
As shown in FIG. 2, the means by which the upper end of the reflector is coupled is protruded from the end of each of the protrusions at both ends of the plurality of protrusions forming the LED substrate mount 11 in the direction of the diffusion plate engaging portion 12 And a first protrusion 14 for the reflector which is newly formed.
2, the means by which the lower side end of the reflector is coupled includes a second protrusion for the reflector 15 protruding from one end of the diffusion plate engaging portion 12 in the direction of the first protrusion 14 for the reflector, )to be.
Accordingly, the reflector 70 is disposed between the two protrusions 14 and 15, and the two reflectors 70 are coupled symmetrically with respect to the center of the LED frame 10. In this case, since the left and right reflectors 70 are coupled with each other at an angle which widens the distance between the left and right reflectors from the upper part to the lower part, efficient lighting can be used with higher illuminance than the applied power.
In this case, the inner wall of the portion between the LED substrate mounting portion 11 and the diffusion plate coupling portion 12 may be formed of a metal or a metal having a high reflectance. Resin or a resin. There is no limitation on the coating method, and it is preferable to use a pure silver coating, but it is also possible to coat the resin with aluminum or to replace it with a white paint coating or stainless steel considering cost and efficiency appropriately.
The LED frame of the present invention can be coupled to other wiring ducts, and is most preferably used in a wiring duct integrated lighting fixture previously proposed by the present applicant.
It is necessary to perform an additional process such as opening the lower surface of the raceway. However, in addition to the interference fit between the wiring duct and the LED frame, a separate clip It is possible to construct even a simple process at a minimum, and it is also possible to simultaneously store communication and other electric wiring other than the lighting wiring, and at the same time, The occupancy can be reduced to one third or less of that of the conventional raceway system, and thus can function as an optimal lighting system.
