Q:Does the LED street lamp work well with a single light source or with integrated light sources?

You look at the voltage LED power supply, generally 12V, white light, you can string 4

Q:How is the minimum illuminance of LED street lights Emin obtained? How to calculate?

If you want to measure the value, I can only say that the approximate, because the illuminance value on a point value, the actual measurement is the target area is divided into small areas of uniform, center to measure each region with the value of the measured value, there is a minimum value.

Q:Compared with LED street lights, what are the advantages of graphene street lamps?

And if compared to ordinary sodium lamp, but also can save energy 70%. Thus, on the basis of the same amount of electricity, graphene street lighting will be higher, and this benefit can also benefit drivers traveling on the road. Almost all of the common LED lamp has a "black light", but the street surrounding light, but dark; and graphene Street due to changes in brightness and light, can avoid this effect of road crossing chiaroscuro "".

Q:The 6 meter high watt LED bulb lamp should match

Generally equipped with 30W led, Yangzhou is the country's largest production base of street lights, manufacturers can visit to see.

Q:Where can I buy LED street lamp and aluminum alloy shell, what's the quality of the product? Who can provide?

Where can I buy LED street lamp and aluminum alloy shell, what's the quality of the product? Who can provide?

Q:LED street lamp burning black what reason?

Is the chip breakdown, for high power, voltage and current are range, is mainly caused by insufficient heat, heat is not enough epoxy resin black, phosphor decay too fast, so that the chip looks black.

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:Do you think it is expensive to install LED street lamp with WIFI function?

There are WIFI street lamps, high cost is a new thing after all, there is no ground for blame, market and breakthrough in technology cost is taken into account, not to mention the WiFi function with LED lights you said also relates to the control and network problems.

Q:What is the design height and illuminance of LED street lamps?

1, the first screenshot of table 5.1.3, Weff means: effective width of the road.2, the above lamps refer to conventional lighting, the so-called regular lighting is the lamp installation height of 15 meters below the lamppost.3, light cut type refers to: the maximum light intensity direction of the lamp and the vertical axis of the lamp included angle between 0-65 degrees.4, half light type refers to: the maximum light intensity direction of the lamp and the vertical axis of the lamp included angle between 0-75 degrees.

Q:What is the principle of constant current power supply in LED street lamps?

Inductors, coils, transformers, these inductors are switching power components, one of the main characters,The role is to assume load or pressure, isolation, filtering and so on.All other components, resistors, capacitors, and protective elements are used.
