Abstract
The present invention discloses an electronic lighting device. The device comprises a plurality of light-emitting diodes mounted on a thermal dissipation base and protected by a translucent cover; said device is specially designed to replace fluorescent tubes, i.e., in relation to its general construction; the electronic lighting device of the present invention has an external shape similar to the standard shapes of conventional fluorescent tubes, and an internal electronic circuit responsible for converting the electrical signal from any reactor into an electrical signal applied to light-emitting diodes. The present invention is free from a printed circuit board, and does not require the use of heat dissipation paste.

A high-power light emitting device comprising:
- a thermal dissipation base having a heat sink with a dielectric layer onto which a metal track and a plurality of metal islands are fixed;
- a plurality of light-emitting diodes having electrical terminals, each one fixed to at least one of said plurality of metal islands and electrically connected through said metal track forming an electronic circuit;
- a translucent lens attached to said thermal dissipation base;
- a pair of circular side covers having metal pins on their outer faces wherein both of the pair of circular side covers have a circumferential dimension allowing said pair of circular side covers to fit over a circular profile formed by a junction of said heat sink and said translucent lens.
A high-power LED lighting device comprising:
- a thermal dissipation base comprising a heat sink having an oxide layer onto which a metal track and a plurality of metal islands are fixed;
- a plurality of light-emitting diodes having electrical terminals, each one fixed to one of said plurality of metal islands and electrically connected through said metal track forming an electronic circuit;
- a translucent lens attached to said thermal dissipation base;
- a pair of circular side covers having metal pins on their outer faces wherein both of the pair of circular side covers have a circumferential dimension allowing said pair of circular side covers to fit over a circular profile formed by a junction of said heat sink and said translucent cover.
