[0016] Example 1
[0017] Such as figure 1 As shown, the integrated high thermal conductivity substrate LED lamp includes a thermally conductive lamp body 10 and an LED light bar 20. The outer side wall of the thermally conductive lamp body 10 is provided with a plurality of receiving grooves 11 for accommodating the LED light bar 20. The LED light bar 20 includes a high thermal conductivity aluminum substrate and LED lamp beads 21 arranged in an array on the front surface of the high thermal conductivity aluminum substrate. The high thermal conductivity aluminum substrate includes a circuit layer, a high thermal conductivity insulating layer, and a copper plate layer. The lamp beads 21 are electrically connected, the high thermal conductivity insulating layer is fixed between the circuit layer and the copper plate layer; the copper plate layer and the containing groove 11 are encapsulated with high thermal conductivity LED packaging glue.
