Embodiment Construction
[0023] The principle and structure of the present invention will be further described below in conjunction with the accompanying drawings.
[0024] Such as figure 1 Shown is a top view of the aluminum substrate used for LED packaging in the embodiment of the present invention. According to the number of LED chips to be packaged, round holes are punched on the common aluminum plate 1 . The mirror aluminum plate 2 with the same length and width as the ordinary aluminum plate 1 is taken, and it is pressed at high temperature to become one body after pressing. The holes of the ordinary aluminum plate 1 and the mirror aluminum plate 2 form a circular groove 3 .
[0025] The ordinary aluminum plate 1 and the mirror aluminum plate 2 have the same shape and size.
[0026] The thermal conductivity of the mirror aluminum plate 2 is 1.3 times that of the ordinary aluminum plate 1, and has a good reflective effect, with a reflectivity of 85% and high tensile strength.
[0027] Such as ...
