Introduction to the LED street lamps and lighting design standard in tendering documents

Difference is LED street lamp with conventional street lamps, the LED light source adopts low voltage DC power supply, by GaN power type synthetic efficiency white light, blue light leds and yellow is efficient, safe, energy-saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, can be

LED street lights and the difference between the traditional street lamp, LED light source with low voltage DC power and gallium nitride based power synthesis efficiency white light, blue light emitting diode and yellow is efficient, safe, energy-saving, environmental protection, long service life, fast response speed, high color rendering index unique advantages, can be widely used in road. High temperature can reach 135 degrees, can reach - at low temperature 45 degrees. Led street lamp design has the following requirements: 1 using the path of light emitting diode lamps and lanterns should make full use of the characteristics of the directional light emitting diode lamps and lanterns of each light emitting diode can directly on the road will be lighting the light to the pavement in different regions, and then using auxiliary light distribution of reflector lamps and lanterns, to realize the reasonable comprehensive road lamps and lanterns light distribution. 2. LED street lamp power supply system is different from the traditional light source. Light-emitting diodes, especially need constant current drive power is the foundation of guarantee its normal work. Simple solutions tend to switch power supply damage to light emitting diode device. 3, light emitting diode drive circuit between each point and ground clearance should be kept in more than 7 mm, used to prevent electromagnetic interference of grounding capacitance and power circuit of the insulation strength should satisfy reinforced insulation ( 4V+2750V) Request, make the light emitting diode drive circuit has good ability to resist differential mode and common mode of lightning induction. Co-founder of the company is engaged in road lighting research and development and production has more than 10 years, the network marketing and management, and established the solar companies here. Focus on and stick to the Internet, we are committed to the Internet in China and the construction of a famous leading road lighting enterprise.
