Description

차량용 엘이디램프{LED LAMP FOR AUTOMOBILE}Vehicle LED lamp{LED LAMP FOR AUTOMOBILE}

본 발명은 각종 차량의 실내등이나 넘버등으로 이용되는 차량용 엘이디램프에 관한 것이다.The present invention relates to a vehicle LED lamp used as an interior light or number of various vehicles.

일반적으로 각종 차량의 실내등이나 넘버등(일명 Festoon Bulb) 등으로 이용되는 엘이디램프(Light Emitting Diode Lamp)는 공개특허 10-2017-0102611호 '자동차 실내등용 엘이디램프 및 그 제조방법' 및 등록특허 10-1840449호 '차량용 엘이디램프 유니트' 등과 같이 인쇄회로기판의 상부에 엘이디소자를 실장하여 엘이디램프를 얻은 다음 인쇄회로기판 하부에 갖는 접속부를 이용하여 소켓에 꽂아서 전원공급이 이루어지도록 구성된다.In general, the LED lamp (Light Emitting Diode Lamp) used as an interior light or number lamp (aka Festoon Bulb) of various vehicles is disclosed in Patent Publication No. 10-2017-0102611'LED lamp for automobile interior light and its manufacturing method' and Registered Patent 10 Like -1840449'Vehicle LED Lamp Unit', an LED element is mounted on the upper part of a printed circuit board to obtain an LED lamp, and then power is supplied by plugging it into a socket using a connection part under the printed circuit board.

그러나 상기한 차량용 엘이디램프는 인쇄회로기판이 갖는 접속부가 인쇄회로기판 고유의 매끈한 판형으로 이루어져 있어 소켓에 꽂아줄 시 단순히 소켓이 갖는 탄성단자의 탄성에 의해서만 결합력이 주어지게 되므로 차량운행시 엔진이나 또는 불규칙한 노면 등에 의해 진동이 주어지게 되면 소켓으로부터 엘이디램프가 쉽게 분리되어 제기능을 상실하게 된다.However, in the above-described vehicle LED lamp, the connection part of the printed circuit board is made of a smooth plate shape unique to the printed circuit board, so when it is inserted into the socket, the coupling force is given only by the elasticity of the elastic terminal of the socket. When vibration is applied by irregular road surfaces, the LED lamp is easily separated from the socket, and its function is lost.

따라서 엘이디램프를 소켓에 꽂아줄 시 소켓과의 결합이 견고하게 이루어질 수 있도록 하기 위한 엘이디램프에 대하여 이미 등록실용신안 20-0461954호 '차량용 엘이디램프의 광확산커버'가 제공된바 있으나, 이는 인쇄회로기판의 접속부에 걸림홈과 접속단자를 갖는 별도의 걸림구를 결합고정하여 상기 걸림구를 이용하여 소켓에 꽂아주게 되면 걸림구가 갖는 걸림홈과 소켓이 갖는 탄성단자의 걸림으로 강한 결합력이 주어지도록 구성되므로 이는 인쇄회로기판의 접속부에 걸림홈과 접속단자를 갖는 별도의 걸림구를 결합고정하여 사용하는데 따른 제조원가상승으로 제품의 가격경쟁력이 떨어지게 되는 등의 문제점들이 있는 것이다.Therefore, registration utility model 20-0461954'Light diffusion cover for vehicle LED lamps' has already been provided for LED lamps to ensure a solid connection with the socket when the LED lamp is inserted into the socket, but this is a printed circuit. When a separate locking hole having a locking groove and a connection terminal is coupled and fixed to the connection part of the board and inserted into the socket using the locking hole, a strong coupling force is provided by locking the locking groove of the locking hole and the elastic terminal of the socket. Since it is configured, there is a problem in that the price competitiveness of the product decreases due to an increase in manufacturing cost due to the use of a separate locking hole having a locking groove and a connection terminal in the connection part of the printed circuit board.
