Can be used to make double -colored temperature ceramic substrate of LED

The utility model discloses a can be used to make double -colored temperature ceramic substrate of LED, including ceramic substrate and setting a plurality of align to grid's on ceramic substrate double -colored temperature pad area, every double -colored temperature pad area include double circle silica gel dam, hinder and weld insulating strip, positive pole and bicathode altogether, double circle silica gel dam set up the intermediate position at double -colored temperature pad area, hinder and weld insulating strip and connect respectively on circular silica gel dam and extend to common positive pole and bicathode respectively, the bicathode set up respectively at the upper and lower both ends of double -colored temperature pad area with one side, common positive pole setting at the lower extreme of double -colored temperature pad area opposite side. In this way, the utility model provides a double -colored temperature ceramic substrate of LED, rational in infrastructure, the laminating is convenient, and the adhesion is good, and is high temperature resistant, and production efficiency is high, is difficult for appearing the rosin joint phenomenon, is provided with three polarity simultaneously, and one is total to positive pole and two negative poles, has reached the effect of double -colored temperature.
