Abstract

An LED lamp apparatus comprises a plurality of LED lamps including at least one LED chip mounted on a printed circuit board, on which a driver circuit and/or a control circuit are provided in a printed circuit pattern to drive and/or control the LED chip, at least one female lead electrode terminal constituted as a hollow coupling pin to be inserted into at least one through holes for at least one power source terminal and a control signal tenninal and a body made into a unit of the LED lamp, using transparent or translucent epoxy resin, in which the LED lamps are arranged in series or parallel to form a predetermined block, the driver and control circuits are respectively or collectively provided in the block, and one block or a plurality of blocks arranged in series or parallel are made into a body to be molded into transparent or translucent epoxy resin to form a case.

Claims

1. An LED lamp apparatus comprising:

an LED lamp including at least one LED chip mounted on a printed circuit board, at least one female lead electrode terminal fitted into at least one through hole which is perforated on the printed circuit board, into which a metal power source terminal is formed or a hollow coupling pin is inserted and a body forming an unit of the LED lamp with transparent or translucent epoxy resin;

a driver circuit mounted on the printed circuit board and electrically connected to the female lead electrode terminal to drive the LED chip;

a control circuit mounted on the printed circuit board to control the operation of the LED lamp adjacent to the driver circuit or driven LED lamp; and

at least one case including a plurality of blocks, each of which includes a plurality of the LED lamps connected in series and parallel to each another, the block being scaled in the case with transparent or translucent epoxy resin, in which the driver and control circuits are provided in the block by a number set for the use purpose of the LED lamp apparatus to enable various applications.

2. The LED lamp apparatus as claimed in claim 1, wherein:

the LED lamp apparatus further comprises a plurality of cases in which a number of the LED lamps having the driver circuit and a number of the LED lamps having the control circuit are mounted at the same time.

3. The LED lamp apparatus as claimed in claim 1, wherein:

the driver circuit includes driver elements related to the LED chips.

4. The LED lamp apparatus as claimed in claim 1, wherein:

the control circuit is mounted adjacent to the LED lamp having the driver circuit to be operated at the time of driving the driver circuit and forces its LED chips to be delayed for a predetermined time, thereby representing the moving image and picture of characters and graphics.

5. The LED lamp apparatus as claimed in claim 3, wherein the control circuit is mounted adjacent to the LED lamp having the driver circuit to be operated at the time of driving the driver circuit and forces its LED chips to be delayed for a predetermined time, thereby representing the moving image and picture of characters and graphics.
