Description

LED lighting of connector type having a separated converter and method for installing it}

The present invention relates to a connector type LED luminaire with a separate converter and a method of installing the same.

LED lighting fixture is a fixture that uses the light emitted from the LED light source indoors or outdoors. In general, LED lighting fixtures are characterized by being more efficient than general lighting fixtures using other light sources.

1a to 1c is a view showing the LED lighting fixture installation process according to the prior art. 1A to 1C, the ceiling 110, the bracket 120, the bracket bolt 121, the coupling nut 122, the back box 130, the supporter pin 131, the converter 132, and the printed circuit The substrate 133, the LED 134, the DC wire 135, the ceiling support 136, and the light emitter 140 are shown.

According to the prior art, since the printed circuit board 133 is formed integrally with the light box 130 in the side of the appearance of the light emitting surface emitting light, the bracket bolt (when fixing the light box 130 to the ceiling 110) In order to insert the coupling nut 122 into 121, the distance between the printed circuit boards 133 should be at least greater than the width of the coupling nut 122. This structure results in dark areas where LED light is not sufficiently emitted. That is, referring to FIG. 2D, which is made of a line-type light source in which the entire light emitting surface of the lighting fixture does not emit uniformly, the portion where the LED is located is bright and the remaining lighting fixture portion is dark. Here, FIG. 2 is attached to the ceiling bracket (A) of the lighting fixture to which the printed circuit board is partially coupled (B), the power is applied to the LED (C) and then the light transmitting portion 140 through which light passes is installed The process D is shown. Such lighting fixtures have a problem of causing glare because light is concentrated in a specific area.

In addition, referring to FIG. 3, a dark part also occurs in a circular LED luminaire. That is, referring to FIG. 3, a gap necessary for manually coupling the nut and the bolt to connect the luminaire to the bracket is formed between the printed circuit board 133 to generate a dark portion. Here, Figure 3 is after inserting the bracket bolt 121 to the LED lighting fixture (A and A-1), the user manually joins the coupling nut 122 to the bracket bolt 121 (B), the LED The process (D) which installed the cover which light passes after applying power (C) is shown. That is, in the case of the surface light, not the line type, even roughness surface is possible, but when the construction is mounted with the printed circuit board, in order to use the bracket 120 attached to the existing ceiling, the space between the printed circuit boards cannot but be increased. When covering the miner 140 there is a problem that the dark portion occurs in the space.

In addition, in terms of production, installation, AS, etc., the user supports the printed circuit board 133 with one hand in the process of coupling the coupling nut 122 to the bracket bolt 121 to weigh the entire back box 130. The printed circuit board 133 may be damaged because it is in a supported state. In addition, when reducing the gap formed between the printed circuit board 133 to eliminate such a dark portion, there is a problem that the user does not eliminate the gap that generates the dark portion because it is difficult for the user to turn the coupling nut (122).

In addition, in case of using the printed circuit board 133 having a planar shape, the size of the ceiling fixing bracket 120 should be appropriately determined according to the shape and size of the lighting fixture, and the spacing between the bracket bolts 121 coupled to the bracket 120. It should be able to be adjusted wide or narrow. In this case, in the lighting apparatus according to the related art, since the printed circuit board 133 is previously attached to the lighting apparatus, the coupling nut 122 may be coupled to the bracket bolt 121 or the printed circuit board 133 by using the above-mentioned gap. In order to form a predetermined hole, there is a problem in that a separate work time and cost are required, such as manufacturing a customized printed circuit board 133 or modifying a circuit.

In addition, the lighting fixture according to the prior art attaches a plurality of supporter pins 131 in consideration of the thickness of the converter 132 to the back box 130 in view of the manufacturing side and the supporter pins using the printed circuit board 133 using bolts. After fixing on the 131, the DC wire 135 derived from the converter 132 is installed in accordance with a very cumbersome process of connecting the printed circuit board 133 one by one. In addition, in the case of replacing the LED134 in the future in accordance with the user's preference, or when replacing the converter 132, there is a similar inconvenience.

Further, according to the related art, when the printed circuit board 133 and the back box 130 are integrated with the piece fixing and the DC wire 135, the DC wire 135 should be directly connected to the printed circuit board 133. By using the fixing piece 137, there is a need for a hand process of coupling the printed circuit board 133 to the back box 130. This manual process is not only required for the initial construction but also requires a process of disassembling inversely during AS, which causes troublesome installation and disassembly.

That is, when explaining the disassembly process when repairing the lighting fixture, first, after removing the light transmitting portion 140, the coupling nut 122 for fixing the entire lighting fixture is removed from the LED lighting fixture. In order to repair the printed circuit board 133, the fixing piece 137 used to fix the printed circuit board 133 to the back box 130 is removed and removed by a manual process. In addition, when the converter 132 is defective, the entire luminaire is separated from the ceiling 110 to repair or replace the converter 132. LED lighting fixture and ceiling 110 may be coupled by a separate fixing bolt. The assembly process may proceed in the reverse order of this process.

In terms of appearance, thickness and reliability of the luminescent light emitting surface, referring to FIG. 1D, the LED luminaire may include a thickness for accommodating the converter 132 and an LED 134 and a floodlight to prevent glare of the LED 134 light. It becomes thicker by the total thickness T that sums the spaced distance between the 140. This thickness has a problem that the user feels that the thickness of the LED lighting fixture than the general lighting, and also, the heat generated by the mutual heat generated by the converter 132, which is a heating element coexist close to one space with the LED 134, which is another heating element It can be damaged.
