[High-tech LED News] Jining Municipal Department has ordered 1800 ç› LED material new street lamps according to the requirements of roads for street lamps and a supplier in Taiwan. It has been gradually installed.
At present, street lamp manufacturers have proposed several programs, and the street lamps on both sides of Taibailou Road have also become key projects for transformation. The relevant department is under review. According to the preliminary plan, 310 sets of LED street lights will be installed in the south section of Huoju Road, each set worth about 16,000 yuan; more than 1,000 street lights will be built in the section of the West Outer Ring and the airport connecting line nearly 20 kilometers. The current 20,000 street lamps in the urban area will be upgraded and replaced in 5 years, and replaced with new LED street lamps.
According to reports, the replacement LED street light source has an average life of more than 50,000 hours. Each 185 watt LED street lamp saves about 360 kWh per year compared to a 250 watt high-pressure sodium lamp, and reduces carbon dioxide emissions by about 230 kg.

Two - way trigger diode, also known as two - end ac device (DIAC), and two - way thyristor at the same time.Because of its simple structure and low price, it is often used to trigger the bidirectional thyristor, and can also constitute overvoltage protection circuits.Construction, symbol and equivalent circuit of a bidirectional trigger diode.
Also commonly used in the overvoltage protection, timing, shift equal circuit, Figure 2 is the overvoltage protection circuit composed of bidirectional trigger diode and bidirectional thyristor.When the transient voltage exceeds the DIAC and Ubo, the DIAC quickly conducts and triggers the bidirectional thyristor to also conduct, so that the following load is protected from overvoltage damage.
