Abstract
Flexible rod light device containing a string of chip on board (C.O.B.) based LED lamps and manufacturing method thereof are disclosed. The device comprises an inner layer including two parallel upward flanges on sides and a lengthwise top groove between the flanges; a string of C.O.B. based LED lamps comprising a plurality of series connected units each including a C.O.B. based LED lamp secured on the groove and between the flange, one or more conductor means, and a resistor; a pair of main wires parallel disposed within the flanges; and a jacket wrapped up the inner layer and the string of lamps. All lamps are secured and have the same orientation for achieving an increased illumination.
Claims27
A method of manufacturing a flexible rod light device comprising the steps of:
- (a) wrapping a parallel pair of main wires in sides of an inner layer formed of a flexible elongate plastic material by molding wherein the inner layer includes two parallel upward flanges on the sides and a lengthwise top groove between the flanges;
- (b) connecting a first end of an C.O.B. based LED lamp to a first conductor section, a second end thereof to a second conductor section, and interconnecting the second conductor section and the adjacent conductor sector by a first resistor so as to form a connection unit;
- (c) continuing step (b) to form a string of C.O.B. based LED lamps including a plurality of units each including the C.O.B. based LED lamp, two conductor sections, and the resistor.
- (d) placing the string of C.O.B. based LED lamps on the groove and securing the same between the flanges;
- (e) disposing a front most and a rearmost conductor sections on the main wire in a front side and a rear side of the inner layer respectively;
- and
- (f) wrapping up the inner layer and the string of C.O.B. based LED lamps by a material the same as the inner layer by extruding to form a jacket.
A flexible rod light device having concentrated light and increased flexibility to withstand a pulling thereof, the light device comprising:
- a flexible elongate plate-shaped inner layer formed of a transparent or half-transparent plastic material including two parallel upward flanges on sides and a lengthwise top groove between the flanges;
- a string of C.O.B. based LED lamps comprising a plurality of series connected units each including a C.O.B. based LED lamp, a first conductor section and a second conductor section coupled to a first end and a second end of the C.O.B. based LED lamp, respectively, and a first resistor interconnecting the first conductor section of a unit and the second conductor section of an adjacent unit so that the string of C.O.B. based LED lamps are secured on the groove by clinging between the flanges;
- a pair of main wires disposed within the flanges wherein a front most and a rearmost conductor sections are rested on the main wires in a front and a rear sides of the inner layer respectively;
- and
- a jacket, formed of the same material as the inner layer, wrapped up the inner layer and the string of C.O.B. based LED lamps.
