Range Introduction

By maximizing energy savings and providing uniform and comfortable white light, ZD902 18W/36W series are perfectly adapted to illuminate public spaces in cities such as foot and cycle paths, urban and residential streets, parking lots, rural road and courtyard.

The performance, energy savings, and uniformity of these luminaries allow them to be a one to one replacement for standard HID luminaries. With 12v/24v DC interface, they are also applicable to be integrated into solar lighting system.

Features

*Excellent uniformity and target efficacy.
*Energy saving and maintenance free.
*Long lifetime of 35000 hours.
*Incorporates the latest LED technology.
*Solar lighting system interface available.
*Luminairies is rugged made by low copper aluminum with weathertight LED driver compartments and high performance heat sinks..
*Patented all-in-one heat dissipation technology.

*Slim, low profile, minimizing wind load requirements.

Q:How many watts are the street lights?: This comes from the needs of the road. Generally 8 meters below the design of the use of 250W or so street lights, more than 8 meters designed to use 400W high-pressure sodium lamp.

Q:Technical requirements for LED street lamps: The average illuminance of illumination uniformity (uniformityof, road, surfaceilluminance) is 0.48, and the spot ratio is 1:2.5. accord with road illuminance. The actual 1/2 center spot reaches 25LUX, and the 1/4 center light intensity reaches 15LUX, the minimum light intensity is 4LUX at 16 meters, and the overlap light intensity is about 6LUX.6., it has a very good application prospect in the new city lighting. Dimming for depth, and colors and other features are not subject to dimming.7. meet the humidity: less than 95.

Q:How many lights can a high-power LED lamp be at least W?: High power LED street lamp, as the name suggests, is a single power greater than 1 watts, using a new type of LED semiconductor light street lamps. At present, the standard of LED street lamps is generally the average illuminance of (uniformity of road surfaceilluminance), which is greater than 0.42 of the national standard. The spot ratio is 1:2, which conforms to the illumination of the road. The actual 1/2 center spot reaches 25LUX, and the 1/4 center light intensity reaches 15LUX, the minimum light intensity is 4LUX at 16 meters, and the overlap light intensity is about 6LUX.

Q:How many watts is the LED street light 30W-900M?: 30W is the W number of street lights. 900M, is the current power supply, 30W lamp 900 Ma, more heart lighting to help you

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: 611 lights should be divided into at least 10-20 parallel units.

Q:What's the reason for the flash of LED street lights?: 1, should be the power line diameter is small, the power one start, the back voltage is low, so the street lights flash2, the other 18 pull a pair of power lines.3, the front 18 lights closed, leaving only the back 18 can be confirmed.4, the first 18 and the latter 18 do not start at the same time.

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:What's the price of the LED road lamp holder?: Depending on the power, the higher the power, the more expensive.Another look at the configuration, including LED chip, power driven, shell material.

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:LED good or low frequency electrodeless lamp?: LED is a point light source, and electrodeless lamp belongs to the area light source. LED has a strong advantage in low voltage, but it is not mature to make high voltage technology.
