Description

A DETACHABLE TYPED LED FACTORY LAMP

The present invention relates to an LED factory and the like, and more particularly, to an LED factory and the like which are suitable for detachably mounting a reflector so as to facilitate storage and transportation and reduce logistics costs.

In general, a luminaire used for lighting is used in various forms such as a fluorescent lamp, an incandescent lamp, a factory lamp, a street lamp, and a security lamp. In recent years, LEDs have been widely used because of their advantages such as low power consumption and semi-permanent lifetime.

The lighting device using the LED mainly uses a substrate on which a plurality of LEDs are mounted. However, since the LED generates a large amount of heat due to a high heat generated by the LED, there is a limitation in increasing the power consumption, there was. For this reason, a lighting device using a conventional LED basically adopts a heat dissipation structure.

These LEDs are widely used for general lighting, building decoration, mood, traffic lights, indoor and outdoor signs, guidance lights, warning lights, light sources for various security devices, and light sources for sterilization or disinfection.

On the other hand, factory lamps are hung from used ceilings in factories (factory assembly lines), large warehouses, sports facilities or large-scale marts and facilities, and illuminate the interior by illuminating the lower part. There are many cases where LEDs are applied to factories.

As a conventional technology related to such an LED factory and the like, there are known a registered patent publication No. 10-1541522 (Publication date: 2015.08.03) and Published patent publication No. 10-2016-0066569 (publication date: June.06, 2013).

First, the technology according to the above-mentioned Japanese Patent Application No. 10-1541522 can reduce the weight by integrating the main body and the heat dissipating portion. The heat dissipating portion is exposed to the outside to sufficiently dissipate the heat generated from the LED module, And the LED module and the reflector can be replaced according to the required brightness and the irradiation angle.

In addition, in the technique disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 10-2016-0066569, a flexible PCB substrate is applied and mounted on a brass PCB substrate, and chip pads and LED die chips are connected in parallel on both sides with a wire made of gold The remaining die chips are electrically energized to illuminate, and a mixture of a mixture of a liquid epoxy and a phospho (phosphor material) is first applied to the die chip, and the second die is coated with the entire flexible PCB substrate And it is a technical object to extend the lifetime of the lighting module for a long time by waterproofing the lighting module.

However, all of the above-described conventional technologies have a disadvantage in that the reflector is fixedly mounted on the heat sink, so that the reflector is integrally joined and the product is completed and packaged and transported in a bulky state.

As described above, since the reflector is integrally provided, the product is bulky and inconvenient for packaging and transportation as well as the cost of logistics is increased.

In addition, there are some luminaire which do not need a reflection goggle. In this case, there is a problem that it can not meet the demand of the consumer because of the configuration of the unnecessary reflection goggle.

In a detachable LED factory or the like according to an embodiment of the present invention, a seating groove 125 is formed upwardly from the bottom of the heat sink 120, and the screw groove 125a is formed in the inner peripheral surface of the seating groove 125 And a neck 191 in the form of a circular tube is formed on the upper end of the reflector 190. The thread 191a is formed on the outer circumferential surface of the neck 191. [

An LED module 110 mounted on an upper surface 125b of a seating groove 125 of the heat sink 120 and having a plurality of LEDs 111 mounted thereon, A heat sink 120 provided on the upper surface of the LED module 110 and a cable 120 connected to the LED module 110 so as to penetrate through the center of the heat sink 120 and radiate heat generated from the LED module 110. [ A first cable passing hole 122 through which the first cable passing hole 122 passes and a first mounting hole 122 formed in the center of the heat dissipating plate 120 and communicating with the first cable passing hole 122, And a second cable passage hole 140a through which the cable Ca passes are formed in the longitudinal direction so that the flange portion 143 protrudes outward in the radial direction And the first mounting hole 132 and the screw hole 143 are formed below the flange portion 143 with respect to the flange portion 143, A waterproof bolt 140 having an upper threaded portion 142 formed on the upper side of the flange portion 143 and a waterproof bolt 140 formed on one side of the waterproof bolt 140 or the heat sink 120 (Not shown) or hangers 181 and 182 for medals in a fixed body (not shown).

At this time, a cable Ca connected to the LED module 110 is inserted through the first and second cable passing holes 122 and 140a and the lower screw portion 141 is inserted into the first mounting hole 132, The flange 143 is closely attached to the upper surface 130a of the boss 130 to prevent rainwater or moisture from penetrating into the first mounting hole 132 and the first cable passage hole 122 .

According to this, there is an advantage that the waterproof function can be implemented by the simple structure of the waterproof bolt 140. [

Needless to say, the cable Ca has a plurality of electric wires C1.

In the detachable LED factory or the like according to an embodiment of the present invention, the first mount hole 132 has a ring-shaped mount 134 formed to step outward from the inner circumferential surface of the first cable through hole 122 Is formed.

The LED module 110 may be a detachable LED factory according to an embodiment of the present invention. The LED module 110 may include a cable Ca (not shown) interposed so as to pass through the first mounting hole 132 and the first cable passing hole 122, The lower end of the waterproof bolt 140 is installed in the first mounting hole 132 so that the lower end of the waterproof bolt 140 is mounted on the mounting stage 134 and the upper end thereof is closely attached to the lower end of the waterproof bolt 140, When the LED module 110 descends downward while being screwed to the first mounting hole 132, the waterproof bolt 140 is deformed in the radial direction by pressing in the vertical direction, And a compression tube 150 made of a stretchable material for compressing the cable Ca and the inner circumferential surface of the first mounting hole 132 at the same time by deforming in the horizontal direction.

According to the compression tube 150 made of a stretchable material as described above, it is possible to completely block the rainwater or moisture penetrating through the second cable passage hole 140a by the deformation in the horizontal direction, ), It is possible to block the penetration of moisture.

In addition, since the compression tube 150 compresses the cable Ca on which the electric wire C1 is installed, moisture penetrated through the cable Ca can be cut off.

Accordingly, rainwater or moisture can be prevented from permeating between the waterproof bolt 140 and the first mounting hole 132 more reliably.

In the detachable LED factory or the like according to an embodiment of the present invention, a third cable passage hole 170a, which is closely attached to the second cable passage hole 140a and through which the cable Ca passes in the longitudinal direction, And the cable Ca is inserted into the third cable passage hole 170a so as to be inserted into the second cable passage hole 140a, The tube 170 closely contacts and holds the cable Ca by elasticity due to the elasticity, and at the same time, completely seals the space between the second cable passage hole 140a and the cable Ca to block penetration of moisture or rainwater .

According to the above configuration, since the insert tube 170 holds the cable Ca by elasticity, there is an advantage that it can catch the flow of the cable Ca.

Further, below, the compression tube 150 holds the cable Ca by compression, and the insert tube 170 at the top holds the cable Ca by elasticity, so that the cable Ca becomes more rigid There is an advantage that the heat sink 120 can be stably supported.

In the detachable LED factory or the like according to an embodiment of the present invention, the insert tube 170 is made of resin or rubber.

1, 3, 4, 6 and 11, in a detachable LED factory or the like according to an embodiment of the present invention, the hanger 181 is fixed to an upper screw portion of the waterproof bolt 140, And a waterproof hanger 181 formed with a second mounting hole 181a to be screwed to the body 142 and formed with a ring 181 for medals in a ceiling or a fixed body (not shown).

Hereinafter, a method of manufacturing a detachable LED factory or the like according to an embodiment of the present invention will be described.

The cable is inserted into the LED factory or the like. That is, the cable Ca is inserted so as to pass through the first and second cable through holes 122 and 140a.

The waterproof bolt 140 is screwed into the first mounting hole 132 while the compression tube 150 is inserted into the first mounting hole 132 of the boss 130 (see FIG.

When the lower threaded portion 141 of the waterproof bolt 140 presses the compression tube 150 downward in the process of screwing the waterproof bolt 140 to the first mounting hole 132, the compression tube 150 is compressed The cable Ca and the inner peripheral surface of the first mounting hole 132 are simultaneously pressed by deformation (distortion) in the horizontal direction due to deformation (i.e., horizontal distortion) in the radial direction.

The waterproofing between the cable Ca and the waterproof bolt 140 is realized by simultaneously pressing the inner circumferential surface of the first mounting hole 132 while the compression tube 150 is crushed in the horizontal direction, It is possible to realize waterproofing of the cable Ca itself, that is, waterproofing of the inside of the cable.
