西德 DAT 公司由于采用最先进的粘接工艺得以生产直径16毫米的大型发光二极管,它比通常的发光二极管大几倍。发光二极管的顶端设计成半球形,因此读出角度极大,直至180度。由于这种发光二极管的发光强度高,均匀性好,既使在很远的距离也能清楚地辨读。这种大型发光二极管有单色(红色或绿
Due to the state-of-the-art bonding process, West Germany DAT produces large 16 mm diameter LEDs that are several times larger than typical LEDs. The top of the LED design hemispherical, so the reading angle is great, until 180 degrees. Because of this light-emitting diode high luminous intensity, good uniformity, even at great distances can be clearly read. This large light-emitting diode has a monochrome (red or green
