Embodiment Construction
[0027] Figure 4 What is shown is a top view of an LED chip structure according to the present invention. Such as Figure 4 As shown, the LED chip includes a P electrode and an N electrode, wherein the N electrode is located (or approximately located) at the geometric center of the chip, and the P electrode includes a transparent electrode and a thickened electrode, wherein the transparent electrode is located around the N electrode. As mentioned earlier, when the LED is working, the current flowing into the P electrode tends to choose the conduction path with the least resistance to reach the N electrode. Therefore, it is better to enter the N-type material layer from the boundary of the "hollow" ring in the transparent electrode. , and the effect of entering the N-type material at a distance from the boundary of the central ring is secondary. Therefore, it can be considered that the luminous effect of LEDs in a certain place is negatively correlated with the "distance to t...
