Title:
LIGHT EMITTING STICK HAVING LED CHIPS
Document Type and Number:
WIPO Patent Application WO/2008/074218
Kind Code:
A1
Abstract:
A light emitting stick having LED chips (9) is disclosed. The light emitting stick comprises
a strip shaped frame (7), a circuit board (8) and a plurality of LED chips (9). The
upper part of the frame has a groove (701), and the lower part of the frame has a plurilty
of vertical holes (702). The top of each of the vertical holes (702) and the bottom
of the groove (701) are feedthrough. A negative pole plate (11) is placed on the
upper surface of the circuit board (8), and has a plurality of throughholes (111).
The position of the throughholes (111) corresponds to the position of the vertical
holes (702). The circuit board (8) has a pluralityof positive pole pads (12).
The positive pole pads (12) are exposed from the throughholes (111) on the negative
pole plate (11), respectively. The bottom surface of the frame (7) bonds to the
negative pole plate (11). The LED chips (9) are embedded into the vertical holes
(702) of the frame (7), respectively. The positive terminal wires (902) of the
LED chips (9) are connected to the positive terminal wires (902) of the positive
pole pad (12) one by one, and the negative terminal wires (901)of the LED chips
(9) are connected to the negative pole plate (11) of the circuit board (8) one by
one. The inner walls of the groove (701) form reflective walls.
