Q:How many watts are the street lights?

Power ranging from fifty to several thousand, as well as mercury vapor lamps, sodium lamps, LED lights and the like

Q:How many LED lights are there in the downtown area, W?

200W, 12 meters high, 4 lanes160W, 10-12 meters high, 3 lanes, 4 lanes120W, 8-10 meters, 3 lanes80W, 6-8 meters, 2 lanes, 3 lanes

Q:What is the heat dissipation principle of a LED street lamp?

The road lamp with outdoor use at night, located on the side of the radiating surface above as well as restricted small benefit to the air natural convection, so LED road lamp cap recommendations as far as possible to choose natural convection cooling.

Q:How much is the LED street lamp?

This side needs to provide the lamp post caliber, wall thickness, height, in addition, Kazakhstan needs to provide light source size and lamp cap style, so as to accurately quote the price.

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:Does the LED street lamp 80W or 100W need to be compensated by a single light capacitor?

Capacitor compensation is reactive power compensation or power factor compensation. The power system of electric equipment in use will produce reactive power, and is usually inductive, it will make use of the capacity of power efficiency, and by increasing the capacitance of the way properly in the system can be improved.

Q:LED technical requirement of street lamp 100W

LED light source technical requirements:(1) LED light source chip requires the use of internationally renowned brands (American CREE CREE, German OSRAM Osram and Holland PHILPS Philips), and uses low thermal resistance, good heat dissipation and low stress packaging technology.(2) using high luminous efficiency LED chip. LED chip luminous efficiency more than 110Lm/w, no ghosting, low light attenuation.(3) LED light source color temperature 4000K-6000K.(4) LED light source life: no less than 50000h.(5) the general color rendering index LED lamp: Ra = 75, the road evenness in more than 0.4.(6) LED street light 10000 hours less than 8%, the service life of 50 thousand hours, 50 thousand hours less than 30%.

Q:How to select suitable driving power for LED street lamp

A high pole lamp power, there are some low power courtyard street lamp, a power voltage, there are low, are prone areas in lightning, so the constant current drive, not only good performance, but also can be good heat dissipation, anti lightning, anti rain.

Q:How can a LED street lamp protect against lightning strikes?

Internal lightning protection system must be connected with external lightning protection system of overvoltage protector or set in many devices such as housing, import and reserve cable, metal pipe, and equipotential connection.

Q:400W high pressure sodium lamp can replace 150WLED lamp? Luminous flux?

LED lamps instead of high pressure sodium lamps.
