  • LED positioning structure
    Patent number: 7322736
    Abstract: An improved LED positioning structure includes a retaining holder and a cover; multiple slots being disposed on one side of the retaining holder; a slope externally extending beneath each slot gradually and externally extending a slope; a hole connecting through each slot being formed on the bottom of the slope; a positioning channel at the top of the retaining holder for LED pins to respectively penetrate each hole, thus each pin being placed in a slot; a bent part of each pin being formed by the curvature located between the slot and the positioning channel to position the LED mask in the positioning channel; and the cover being positioned at top of the slot to secure the LED in place.
