Abstract
A LED illuminating arrangement with a plurality of illuminating devices connected in parallel with wires aligned at a one-plane manner. The illuminating device comprises a shell formed by injection molding of ABS plastic, an illuminating unit and a sealing arrangement. The shell has a top side, two sidewalls defining two guiding slots for wires passage and one or more chambers indented from the top side. The illuminating unit includes a printed circuit board and one or more diodes mounted on an exposed portion of the circuit board within the chamber in series for providing illumination. The sealing arrangement is made of thermosetting polymer sealing at each chamber, protecting the diode and the exposed portion of the circuit board against water.
Claims22
A LED illuminating device, comprising:
- an illuminating unit which comprises a circuit board, one or more diodes electrically mounted on said circuit board, and a plurality of wires electrically extending from two side edges of said circuit board respectively to electrically connect with said diodes;
- a shell sealing and enclosing said illuminating unit to form a waterproof casing of said illuminating unit, wherein said shell has a top side, a bottom side, and one or more chambers indented from said top side to align with said diodes respectively, wherein said shell forms an integrated enclosure to seal said circuit board therewithin at a position that said circuit board is sealed between said top and bottom sides of said shell, and to seal connections between said wires and said circuit board;
- and
- a chamber seal sealing at each of said chambers of said shell to seal and enclose said respective diodes therewithin, wherein each said chamber seal protects said corresponding diode within said chamber in a waterproof manner.
A LED illuminating arrangement, comprising a plurality of LED illuminating devices being electrically connected by wires, wherein each of said LED illuminating devices comprises:
- an illuminating unit which comprises a circuit board, and one or more diodes electrically mounted on said circuit board, wherein said wires are electrically extending from two side edges of said circuit board respectively to electrically connect with said diodes;
- and
- a shell sealing and enclosing said illuminating unit to form a waterproof casing of said illuminating unit, wherein said shell has a top side, a bottom side, and one or more chambers indented from said top side to align with said diodes respectively, wherein said shell forms an integrated enclosure to seal said circuit board therewithin at a position that said circuit board is sealed between said top and bottom sides of said shell, and to seal connections between said wires and said circuit board;
- and
- a chamber seal sealing at each of said chambers of said shell to seal and enclose said respective diodes therewithin, wherein each said chamber seal protects said corresponding diode within said chamber in a waterproof manner.
A method of manufacturing a LED illuminating device, comprising the steps of:
- (a) electrically coupling one or more diodes on a circuit board and electrically extending a plurality of wires from said circuit board to electrically link with said diodes in order to form an illuminating unit;
- (b) mold-injecting a shell sealing and enclosing said illuminating unit to form a waterproof casing of said illuminating unit, wherein said shell has a top side, a bottom side, and one or more chambers indented from said top side to align with said diodes respectively, wherein said shell forms an integrated enclosure to seal said circuit board therewithin at a position that said circuit board is sealed between said top and bottom sides of said shell, and to seal connections between said wires and said circuit board;
- and
- (c) applying a chamber seal for sealing at each of said chambers of said shell to seal and enclose said respective diodes therewithin, wherein each said chamber seal protects said corresponding diode within said chamber in a waterproof manner.
