Embodiment Construction
[0021] The present invention will be described in detail below with reference to the accompanying drawings: the general-purpose light-emitting diode described in the present invention is mainly composed of a light-emitting diode chip 11 and a metal base for mounting the chip. The metal base is composed of at least one hollow metal tube 12 with high thermal conductivity, and at least two LED chips 11 are fixed on one end or the center of the metal tube 12 . As shown in Figure 2, 12 light-emitting diode chips 11 are directly welded on the tube wall surface of the metal tube 12 by using high thermal conductivity gold-tin alloy or tin sheet, or are bonded on the tube wall surface of the metal tube 12 by using high thermal conductivity silver paste or organic or inorganic glue. On the tube wall, a diode chip ring is formed; the LED chips 11 are evenly distributed on the annular tube wall of the metal tube 12, and they are electrically connected to each other by gold wire 13 ball wel...
