The pleunm anti-static insulated material housing prevents short circuit led by the contact of welding spot and the metal channel of word sign. At the same time, the circuit uses particular constant current design and lightning arrester. Silicon rubber leads between modules of anti-aging and anti-cracking guarantee the long-term work in bad environment of open area while the low resistance of lead reduces the affection to the emitting brightness of LED by voltage drop.

其外壳采用阻燃防静电绝缘材料，可防止 PCB焊点与金属字槽壳的接触而产生短路，同时电路采用独特恒流电路设计及雷电吸收装置，模组间连接线采用软硅橡胶导线，在恶劣的户外恶劣环境下长时间使用，导线不会老化脆裂，同时导线内阻比较小，降低压降对LED发光亮度的影响。

The powers of each line of spectrum were measured and the wavelengths were calculated. Th
