Abstract

A colored or clear transparent diode lens to be covered around an LED includes a cover body and plural clamping walls formed to extend down from the over body. The cover body is formed with an accommodating cavity with a downward opening to be stuck with the upper side of the sealed body of the LED. The clamping ribs extend from the outer side of the groove opening and their inner sides are flush with the outer side the LED. Each clamping walls has the lowermost end formed with a projecting-inward edge to be stuck on the lower side of the LED. The clamping walls and the lower side of the LED and a printed circuit board are combined together with dissolved gum, able to be stably combined with an LED for emitting different-colored warning lights, and having functions of water prevention and heat dissipation.

Claims

1. A colored and transparent diode lens comprising:

A cover body covered around a sealed body of a led, said cover body having its interior formed with a cylindrical accommodating cavity with a downward opening, said downward opening of said accommodating cavity stuck with the upper side of the sealed body of said led; and

A plurality of clamping walls extending from the opening of said cover body, the inner side of each said clamping wall being flush with the outer side of the sealed body of said led, each said clamping wall having the lowermost end formed with a projecting-inward edge, said projecting-inward edge able to be stuck on the lower side of the sealed body of said led.

2. The colored and transparent diode lens as claimed in claim 1, wherein said clamping walls and the lower side of the sealed body of said LED and a printed circuit board are combined together with dissolved gum.

3. The colored and transparent diode lens as claimed in claim 1, wherein a plurality of supporting members extend from the said clamping walls of said cover body, respectively having the lowermost end formed with a projecting-outward edge to be engaged and stuck in the engage hole of said printed circuit board.

4. The colored and transparent diode lens as claimed in claim 1, wherein said cover body could be of any shape for producing different refracting lights.

5. The colored and transparent diode lens as claimed in claim 1, wherein said cover body and said clamping walls are transparent.
