Q:What is the difference between solar LED street lamp and ordinary energy-saving street lamp?: LED solar street lamps use solar photovoltaic cells to provide electricity, solar energy as a new green energy, "inexhaustible" and "endless"".

Q:What are the components of a LED street lamp?: LED lights a lamp, road lamp, aluminum, and mirror (or mirror). Now, large W is the integration of LED lamp, lamp shell and heat radiating aluminum design beautiful integration and good, suitable for high power LED lamp is used. Professional integration of high-power LED street lighting manufacturers, telephone contact below.

Q:LED street lamp, glass lens, mold opening, research and development: LED based two time light distribution design is critical to the performance of final lighting devices and products. The first part of the light, failed to achieve the effective illumination range resulting in energy loss, need high numerical aperture optical system of light gathering, further improve the utilization rate of light energy; second, after packaging, image illumination uniformity can not meet the design requirements, to the lowest illuminance is greater than the value required in the choke each point of illumination, which require the LED two optical design. Ying

Q:Please use LED lamp beads with other lamp beads is not the same?: Are the same, but the quality requirements of the lamp beads more high.

Q:Is the power LED lamp constantly flashing? Is it a power supply problem?: Maybe the driving power is broken, so long as you put on another good driving power, it will not flash.

Q:22 km road, every 33 meters to install a street lamp, street light power 120W, attached to the LED display 60W, a total of 180W, seeking the best laying line program: If there are 20 or so parallel units. Each unit of parallel =0.18x30=5.4KW, 6mm - 10mm - copper or aluminum wire. Light controlled single-phase AC contactor 50A.

Q:Location of constant current source for LED street lamp: Solar street lighting controller is divided into two buck and step-up, Buck 50 yuan, step-up 80 yuan, the warranty for three years. Now the conventional 6 meter 30W power solar energy set price is about 1260 yuan, the detailed price ha needs to calculate according to the lighting time and the rainy days.

Q:Why solar energy centralized power supply street lamp must be supplied by AC LED lamp?: 1: DC transmission distance is limited, the pressure drop is very high2: DC voltage - protection switch, controller parts and other technologies immature or cost slightly higher3: DC wiring voltage is not very high, but the street lamp power is not small, the current will be very high, the cable cost

Q:What is the distance between the usual street lights?: There is no standard, and some are required to achieve the value of illumination, there is no hard and fast requirements, generally speaking, the distance between the street lamp and the lamp height and the number of watts.

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.
