Q: How many kinds of power do LED street lights have? How much brightness can it replace the high pressure sodium lamp? What kind of power does the general main road need?: Generally have 20W, 30W, 50W, brightness can be replaced by 100W, 150W, 200W power high-pressure sodium lamp 30W~50W power is enough for a common trunk road.

Q: Does the LED street lamp need a starter?: LED light is not a starter, is a constant current source module, is 220V city power rectifier, with constant current circuit to each LED lamp power supply; LED lights can be connected in series, and then parallel. There is also not constant current, but in each series of branch current limiting resistors, to consider the range of voltage fluctuations, select the current resistance resistance value and power.

Q: What are the parts of a LED street lamp?: The working principle and design of solar street lamp LED 2008 01 Friday 25 March 22:28 with the world energy crisis intensifies, countries are seeking a solution to the energy crisis, a road is used for new and renewable sources of energy; the other one is looking for new energy-saving technologies, reduce energy consumption, improve the utilization efficiency energy.

Q: What are the 6 main disadvantages of LED street lights? What are the 6 major disadvantages?: Light LEDAfter a period of illumination, the light intensity of LED will be lower than that of the original light

Q: What's in the lamppost of the LED street light? What is the function?: Light emitting diodes (LightEmittingDiode, abbreviated as LED) is a semiconductor pn junction formed with weak electricity can light high efficiency solid-state light source based on the forward bias voltage and the injected current, injected into the P region of the hole and injected into the N region electron in diffusion into the active region after radiation and emit a photon, electric can be directly converted into light energy.

Q: Is there a place where trees can hold LED solar street lamps?: Yes, solar street lights are not covered by trees

Q: What is the heating temperature at the LED street lamp?: Our street light is more than 50 degrees, preferably no more than 60 degrees

Q: How much is the price of the LED street lamp?: It depends on the customer's specifications

Q: High frequency jet lamp, LED lamp, xenon lamp, which is suitable for street lamps: LED light color and soft, to capture and analyze details of road condition eye to night lighting, but due to the LED light emitting chip is heat sensitive, so the steady flow module and a heat dissipation module as big and complex, weight big, cost is very high, but from the actual situation, life did not claim so long. Even the shortest in several light sources. Many places use this as a source of care for the local light source industry.

Q: The power supply of LED street lamp has no influence on the grounding power. The possibility that the power supply will burn out is not big enough: Ungrounded electricity generates static electricity and shortens the life of the lamp.
