Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a slim floodlight and the like, and more particularly, to a new slim floodlight and the like designed to have a completely waterproof structure at a portion where a power cord enters.
Generally, floodlights are installed indoors or outdoors so that light of desired brightness can be inspected in architectural structures, large monuments, various stadiums, various factory facilities, and industrial facilities. As a light source used in conventional floodlighting, metal halide lamps, sodium lamps such as sodium lamps, halogen lamps, etc. are used. These lamps are consumed in a large amount, have a short service life, It has high disadvantages such as polluting environment.
Therefore, recently, LEDs which require low power consumption and have a semi-permanent lifetime characteristic are widely applied as light sources in terms of improvement of illumination and energy saving. On the other hand, in a floodlight using an LED as a light source, heat is generated at the time of light emission of the LED, and a large amount of heat is generated in proportion to such heat generation. In order to satisfy such a heat dissipation function, a heat sink such as a heat sink is often laid on the back surface of the LED light.
Conventionally, there is a problem in that waterproofing between a power cord connected to apply a power source to a light source and a cord inlet part of a light-emitting case can not be properly performed. Conventionally, the sealing between the power cord and the cord entry portion of the light-emitting case is sealed by a sealing member such as a normal packing, but the outer cover of the power cord, two built-in power cord or signal cord and two built- There is no way to protect the rainwater infiltrating into the inside of the power cord when the rainwater penetrates between the lines, and as a result, the rainwater entering the inside of the power cord enters the inside of the light source and short- Causing problems.
SUMMARY OF THE INVENTION The present invention has been developed in order to solve the above-mentioned problems, and an object of the present invention is to provide a waterproof structure in which a waterproof structure is formed at a portion where a power cord is inserted, And to provide a slim floodlight of a new structure capable of preventing a serious problem in advance.
According to an aspect of the present invention, there is provided a display device including: a case having a light source therein; A cord insertion unit provided in the case to receive a cord for connection to the light source; A printed circuit board provided on the cord inlet; A coupling support portion for sealingly securing between the cord inlet portion and the printed circuit board; And a soldering joint for bonding a core wire (copper wire) inside the cord to the printed circuit board to block a gap between the core wire and the printed circuit board.
And a waterproof barrier which is filled in the cord inlet and blocks the soldering joint between the printed circuit board and the inlet end of the cord inlet and between the core wire of the cord and the printed circuit board.
A cord cap inserted from the inlet end is provided in the cord inlet portion, and the waterproof barrier is provided between the cord cap and the printed circuit board.
The waterproof barrier material is formed by filling an epoxy into the cord inlet portion, and the cord cap is integrally coupled to the waterproof barrier material.
Characterized in that the cord is coupled to the cord inlet portion before the epoxy is cured in a state where the epoxy is filled in the cord inlet portion so that the cord cap is integrally bonded to the epoxy when the epoxy is cured .
Wherein the printed circuit board is provided with a wire connecting hole communicated from the outer side to the inner side and the core wire having the cord covering the cord is inserted into the core wire fitting hole, And the space between the core wire and the wire connecting hole is blocked.
The printed circuit board is injection-molded by insert injection molding into the cord entry portion of the case to form the coupling support portion, and the coupling support portion is supported so as to be sealingly engaged with the cord entry portion of the printed circuit board.
The coupling support portion may include an outer sealing member and an inner sealing member that are held in contact with the outer surface and the inner surface of the printed circuit board to support the printed circuit board so as to be disposed inside the cord receiving portion.
Wherein the printed circuit board is attached to the cord entry portion of the case by a tape to form the coupling support portion by the tape and the coupling support portion is supported so as to be sealingly engaged with the cord entry portion of the printed circuit board have.
The coupling support part may include an outer tape and an inner tape which are held in contact with the outer surface and the inner surface of the printed circuit board to support the printed circuit board so as to be disposed inside the cord inlet.
According to another aspect of the present invention, A cord inlet for receiving a cord to be connected to the light source; A cable gland coupled to the cord inlet; And a waterproof barrier disposed between an upper portion of the cable gland and the cord inlet portion to seal the cord inlet portion and the cable gland.
The waterproof barrier material is composed of epoxy cured by filling the inside of the cord inlet part.
The slim projected light according to the present invention blocks only water such as rainwater entering the outside of the power supply cord for light emission of the light source and unlike the conventional one in which water penetrating the inside of the cord can not be blocked, Since the water can be completely blocked, it has an effect of achieving complete waterproofing of the portion where the cord comes in compared with the conventional one. The cord includes an outer sheath and an inner sheath enclosed within the outer sheath wrapped around the core sheath, wherein the inner sheath enters the outer sheath of the cord and rides on the inner sheath so that, even if water reaches the printed circuit board, Since the soldering joint connecting the circuit board completely blocks the gap between the joint between the core wire of the cord and the printed circuit board, it is possible to prevent the water coming in the cord from penetrating into the case through the printed circuit board You can. Unlike the conventional structure, it is a relatively simple structure, but the water entering the inside of the cord is totally prevented from penetrating into the inside of the case containing the light source such as LED and the main printed circuit board, It is possible to completely prevent a safety accident such as a shot or an electric shock by means of the present invention.
