Q:What is the heat dissipation principle of a LED street lamp?
Mainly include: natural convection heat dissipation, fan cooling, heat pipes and loop heat pipes, heat dissipation, etc.. The fan is forced to heat, the system is complex, the reliability is low, and the heat pipe and the loop heat pipe have a high cost of heat dissipation.
Q:Is there any difference between intelligent street lamp and intelligent LED street lamp?
LED light is generally used as a light source, there is no difference between open and close appliances intelligent streetlights.
Q:What are the necessary tests for the factory inspection of the LED street lamp?
High power LED light source (1W-200W), and heat radiation aluminum housing, as well as LED constant current source (power supply). At present, the market LED street lamps are divided into two major categories
Q:Excuse me, LED experts. How many watts do LED street lights usually have on the roads?
Choose different power or combinations according to the width of the road, the density of the street lights and the required illuminance
Q:Why is the higher the current, the lower the light efficiency?
What I know is: junction thermal resistance, spectral distribution drift
Q:What are the parts of a LED street lamp?
Solar energy is one of the most direct the most clean energy, solar energy is a huge amount of renewable energy, each day to reach the earth's surface radiation can be approximately equal to 2.5 millions of barrels of oil, can be said to be inexhaustible. The LED spectra of almost all concentrated in the visible light spectrum, so high luminous efficiency, is generally believed that energy-saving lamp energy-saving 4/5 is a great initiative, but also energy-saving energy-saving lamp LED than 1/4, this is a great reform of solid light source. Solar LED lighting integrates the advantages of solar energy and LED.
Q:How much is a full set of solar street lamps?
Guangya lighting prompts you! A full set of solar street lamps cost between $2500 and $10000, with power ranging from 15W to 100w.There is relationship between the specific price and the solar street lamp solar street lamp configuration, and the solar street lamp is composed of solar panels, batteries, LED light source, controller, main poles and some auxiliary parts prices but also their price and.
Q:How much is the rated voltage of the LED street lamp? Is it direct current?
It is worth noting that, if the solar LED street lights, then certainly the input DC, and as many volts, still depends on the situation.
Q:What is the reason that the longer the wire pulls on the LED street lamp, the lower the voltage?
Resistance will block the passage of electricity; the greater the resistance, the greater the loss of electrical energy in the line.
Q:Does LED street lights save electricity?
The white LED: in 1998, light white LED is only 5 LM / W, in 1999 has reached 15 LM / W, this index is similar to general household incandescent lamps, and in 2000, light efficiency of white LED has reached 25 LM / W, the index and the tungsten halogen lamp is similar. In 2005, the light efficiency of LED was up to 50 lumens / watt. In 2010, the light efficiency of LED reached more than 100 lumens / watt. The working current of white light LED can reach ampere level. Thus, the development of white LED writers using lighting sources, will become possible reality.
