LED Semiconductor Lighting Network News With the development of social economy and the improvement of people's quality of life, people also put forward higher and higher requirements for the urban environment. As a symbol of urban development, urban landscape lighting has also attracted more and more attention. Landscape lighting is an important part of the public lighting system. A good public lighting system helps to form a positive urban image, which not only beautifies the urban environment, but also reflects the economic strength and modernization level of the city.
People-oriented, in landscape lighting places, personal safety should be taken as the first factor, and the selected drive power must meet the corresponding safety standards. In the process of installation and construction, it must be standardized in strict accordance with the manufacturer's instruction manual and relevant operating guidelines. operation and construction; when the lighting circuit and LED driving power supply have electrical failure, in order to prevent personal electric shock, electrical circuit damage and electrical fire, short-circuit protection, overload protection and grounding protection should be provided to cut off the power supply or issue an alarm signal . For this purpose, fuses, circuit breakers and residual current protectors are generally used for protection.
The following aspects should be paid attention to when choosing the corresponding LED driver power supply:
⑴, try to choose the LED drive power with electrical isolation.
(2) The insulation resistance of the live part of the LED drive power supply and the ground terminal is greater than 2MΩ.
(3) The metal shell part of the LED driving power supply must be grounded reliably and clearly marked.
