Q:What is the reason that the range of the LED100W street lamp is not enough or the brightness is not enough?
The LED street lamp has a unique two optical design, illuminating the light of the LED street lamp to the area where the lighting is needed, and further improving the illumination efficiency so as to achieve the purpose of energy saving;
Q:What is the LED lamp light?
LED is English light emitting diode (light emitting diode) abbreviation, its basic structure is a electroluminescent semiconductor chip light emitting materials, with silver glue or glue curing to the bracket, connecting a chip and a circuit board and then with silver or gold, then sealed with epoxy resin around, to protect the internal core role finally, the installation shell, so the seismic performance of LED lamp is good.
Q:What is the reason for the low power factor of LED street lamp?
General LED is the switching power supply to drive, the switching power supply improve power factor method is to increase the power factor correction circuit, power factor correction circuit is generally more than 50W in order to play a role.
Q:How many watts does the LED street light have?
LED street lamp has the characteristics of environmental protection, pollution-free, less power consumption, high light efficiency, long life and so on. Therefore, LED street lamp will be the best choice for energy saving reconstruction.
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:How is the minimum illuminance of LED street lights Emin obtained? How to calculate?
Import the IES file of lamp into DIALux software, and then set up the height, elevation angle, installation interval and so on
Q:How much is the price of a LED street lamp?
The price involves many aspects, generally, for main roads around 120W 1100~1300 are normal; for the auxiliary road around 60~80w 500~800 prices are.
Q:The cold white light LED lamp beads or warm white beads?
The light emitted by neutral white LED has more yellow and red wavelengths, and this spectral distribution helps to distinguish between different liquid surfaces on the tarmac.
Q:LED street lights generally use how many W, how much density is more appropriate?
Most of the 1W with LED, taking into account the heat and street size, the general LED spacing about 30MM is more appropriate
Q:What are the requirements of the LED street lamp chip? How big is it? How many will it take and how big is the distance between them?
To single words, whatever you want a few watts, is generally the number of beads multiples of 7. A single chip is usually 45U, specifically you want what brand, the price is not the same.
