Embodiment Construction
[0025] The content of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments thereof, but should not be construed as limiting the invention.
[0026] figure 1 It is a schematic diagram of the three-dimensional structure of the alumina ceramic substrate in the ultraviolet LED packaging device of the present invention. From the bottom surface of the groove of the alumina ceramic substrate 111 to the top layer of the substrate, there is a narrow strip symmetrical to the center line, which belongs to the area without copper plating as the insulating area. In this way, the insulating property of the alumina ceramic 111 itself divides the conductive copper plating layer 131 into two insulating parts.
[0027] Figure 2-Figure 5 Respectively, the structure I, II, III and IV of the ultraviolet LED packaging device of the present invention are figure 1 Schematic diagram of the longitudinal section structure along ...
