Abstract:
1. A tube elementary light-emitting diode (“LED”) comprising: an elementary glass tube, through which light can be transmitted, the elementary glass tube comprising two sealed ends with a power plug and a power socket, respectively; at least one LED light emitting base plate disposed in the elementary glass tube that is powered by the power plug and the power socket, wherein a plurality of LED chips for emitting light are mounted on one surface of the LED light emitting base plate, wherein bodies of the LED chips are made from microcrystalline LED chips, and PN junctions of the LED chips are first connected in series respectively and then connected in parallel by leads to form an anode lead terminal and a cathode lead terminal, further wherein the LED light emitting base plate is shaped as a strip with a combination of two phosphors with broadband emissions; a plurality of affixing supports affixing the at least one LED light emitting base plate in an internal chamber of the elementary glass tube, wherein the plurality of affixing supports are made of metal; and a reflector attached on the elementary glass tube reflects light emitted from the at least one LED light emitting base plate to outside of the elementary glass tube; wherein, the PN junctions of the LED chips contact with the reflector at a plurality of points through the plurality of affixing supports.
