Light emitting diode backlight package
In a light emitting device including a transparent covering, a fastener having a vertical member and a horizontal member, a light-emitting chip disposed on one face of the vertical member and encased by the transparent covering, a circuit board disposed on one face of the horizontal member, at least one conductive means connecting the light-emitting chip to the circuit board, and at least one heat-dissipating plate perpendicularly disposed on the other face of the horizontal member, light may be emitted longitudinally along a light-guiding plate, thus optimizing the travel path of the emitted light, while maintaining a compact shape by enabling placement of the printed circuit board and heat dissipating plates away from a longitudinal axis of the light-guiding plate.
1. A light emitting device, comprising:
a transparent covering;
a fastener having a vertical member and a horizontal member disposed perpendicular to each other;
a light-emitting chip disposed on one face of the vertical member and encased by the transparent covering;
a circuit board disposed on one face of the horizontal member;
at least one conductive means connecting the light-emitting chip to the circuit board; and
at least one heat-dissipating plate perpendicularly disposed on the other face of the horizontal member.
2. The light emitting device as claimed in claim 1 , wherein the fastener comprises a substantially L-shaped structure.
3. A backlight package comprising:
a light guiding plate having a first side;
a first fastener having a first portion and a second portion, the first portion disposed adjacent to the first side of the light guiding plate, wherein the first portion and the second portion are arranged in a substantially perpendicular relationship to form a substantially L-shaped structure; and
a light emitting device disposed on the first portion of the first fastener for emitting a light toward the light guiding plate.
4. The backlight package as claimed in claim 3 , wherein the second portion extends above the light guiding plate.
5. The backlight package as claimed in claim 3 , further comprising a circuit board and a conducting wire, the circuit board connecting the second portion, and the conducting wire electrically coupling the light emitting device to the circuit board.
6. The backlight package as claimed in claim 3 , further comprising a circuit board and a heat dissipating means, the circuit board connecting the second portion, and the heat dissipating means attached onto the surface of the circuit board for conducting a heat generated thereon.
7. A backlight package comprising:
a light guiding plate having a first side;
a first fastener having a first portion and a second portion, the first portion extending along the first side of the light guiding plate, and the second portion extending above the light guiding plate wherein the first portion and the second portion are arranged in a substantially perpendicular relationship to form a substantially L-shaped structure;
a light emitting device disposed on the first portion of the first fastener for emitting a light toward the light guiding plate; and
a circuit board connecting the second portion of the first fastener; and
a conducting wire electrically coupling the light emitting device to the circuit board.
8. The backlight package as claimed in claim 7 , wherein the first portion is substantially perpendicular to the second portion.
9. The backlight package as claimed in claim 7 , further comprising a heat dissipating means attached onto the surface of the circuit board for conducting a heat generated thereon.
