Introduction of works: DGS70/127B(G) Mine Explosion-proof Roadway Light is a long-lighting lighting fixture suitable for underground narrow roadways. It has beautiful appearance, long light exposure range and high reliability. The roadway light is composed of a housing module, an optical module, a driving module and a mounting module. The outer shell module consists of a triangular lower and upper shell and a wiring chamber cover forming a unique triangular pentahedron, from which light is emitted from two symmetrical faces. The optical module is composed of a light source, a lamp holder and a mirror. The mirror adopts a shape of a geese spreading wings, and the bulb is under the geese body, and the light is reflected to form a narrow light distribution. The drive module is composed of a ballast, capacitor and flip-flop using CWA form circuit, which has strong resistance to voltage fluctuation and high power factor. The mounting module consists of a lifting eye and a side wall mounting bracket to accommodate the lifting eye and side wall mounting.
Main technical indicators: EMI, EMC indicators are qualified, performance is excellent, and more stable. The energy distribution of the original working frequency point can be changed, thereby reducing the energy amplitude and satisfying the limit requirement. Compared with the conventional EMI suppression method, the debugging time can be saved, the number of EMI filtering original devices can be reduced, and the cost can be reduced.
The whole system consists of three parts: PC software, LED lamp wireless controller and LED lamp wireless control terminal. It adopts uC/OS-II embedded operating system based on ARM core and ZigBee and GPRS wireless technology. Network technology research involving wireless networks, intelligent wireless network coordinator components, node components, routing components, network center security component development, lighting centralized control wireless network system message protocol, routing algorithm software, channel access identification software, security policy Software, binding service software, temperature, circuit detection, PWM dimming and other technical points.
Mainly used in urban expressway, trunk road, secondary trunk road, branch road, factory, school, garden, various residential quarters, courtyard and other road lighting.
