技术及工艺创新要点：

全被动元件：被动式LED电源完全由陶瓷功率电容、电抗器、整流桥、电阻、薄膜电容等视为无限寿命的被动式元件组成，不含电解电容、逻辑IC、三极管、MOS管、光耦等在开关电源中必需的易损器件。因此可以在恶劣环境中保证高可靠性和极低故障率，为用户节约维护维修成本。

元件备份脱离技术：被动式LED电源严格遵循电力系统中“N-1”法则设计，任意元件故障不影响整个电源工作，即使出现陶瓷功率电容击穿、电抗器短路等极端情况，仍可维持亮灯，从而保证了极端情况下的亮灯率。
等场强绝缘技术：我公司结合电力高压技术，采用复合RTV材料的包裹型绝缘料件，结合特殊横断面的壳体与灌封工艺，使得电源主体与壳体间的电场强度实现如同电力高压套管一样的均匀分布，实现电源主体与外壳交流12kV的耐压与相地、相间20kV的浪涌耐受能力，从根本上解决了驱动电源难以克服的雷击损坏问题。

Fully passive components: Passive LED power supplies are completely composed of ceramic power capacitors, reactors, rectifier bridges, resistors, film capacitors and other passive components with unlimited life expectancy, without electrolytic capacitors, logic ICs, transistors, MOS tubes, optocouplers, etc. The necessary fragile components in switching power supply. Therefore, high reliability and extremely low failure rate can be guaranteed in harsh environments, saving maintenance and repair costs for users.

Component backup separation technology: The passive LED power supply strictly follows the "N-1" rule design in the power system. Any component failure does not affect the entire power supply. Even if the ceramic power capacitor breakdown, reactor short-circuit and other extreme conditions, it can still keep on lighting , So as to ensure the lighting rate under extreme conditions.
Equal field strength insulation technology: Our company combines power high voltage technology, uses composite RTV material wrapped insulating materials, combined with special cross-sectional shell and potting technology, so that the electric field strength between the main body of the power supply and the shell is as high as electric power The bushings are uniformly distributed to achieve the 12kV AC withstand voltage of the main body and the shell and the surge withstand capability of 20kV between phases and phases, which fundamentally solves the problem of lightning damage that the drive power supply cannot overcome.

实际运用案例和用户评价意见：

山西路桥集团：被动式LED电源产品的初代产品已在我公司隧道运行多年，至今无失效案例，其节能性好，尤其是容性负载特点，为缓解隧道线损问题发挥了极好的节能作用，对我公司隧道照明运维成本的降低提供了极好的帮助。

隧道照明强调二次节能，很多电源标注效率很高，但调光深度大的时候效率不佳，夜间35%亮度传统开关电源的效率只有80%不到，但被动式电源可以做到95%以上，这点我们非常看重。
经过13条隧道的使用，我们对效果非常满意，准备在年底申报成果并发表论文，大力推广基于被动式LED驱动电源新型照明方案。上海市优秀发明选拔赛组委会：该项目产品原理新颖、创新力度大，提供了一种全新思路的LED 电源设计方案，由于其简单巧妙的结构，可以认定其确实具备良好的可靠性寿命优势，建议推广并批量生产。

Shanxi Road and Bridge Group: The first generation of passive LED power products have been running in our tunnel for many years, and there have been no failure cases so far. Its energy-saving performance, especially the capacitive load acteristics, has played an excellent energy-saving role in alleviating the tunnel line loss problem. It provides excellent help to reduce the operation and maintenance cost of our tunnel lighting.

Tunnel lighting emphasizes secondary energy saving. Many power supplies are marked with high efficiency, but the efficiency is not good when the dimming depth is large. The efficiency of traditional switching power supplies with 35% brightness at night is only less than 80%, but passive power supplies can achieve more than 95%. We take this very seriously.
After the use of 13 tunnels, we are very satisfied with the effect, and we are ready to the results and publish papers at the end of the year to vigorously promote the new lighting scheme based on passive LED drive power. Shanghai Excellent Invention Trial Organizing Committee: The product principle of this project is novel and innovative, and it provides a new idea of ??LED power supply design. Due to its simple and ingenious structure, it can be determined that it does have a good reliability and life advantage. Recommend promotion and mass production。
