Q:What is the difference between the brightness and illuminance of LED street lights and the brightness and illumination of ordinary high-pressure sodium lamps?

There must be a difference... Normally。 A 100W LED street lamp, as long as done well, solve the problem of heat dissipation. The light distribution is good and can be equated to a 250W high pressure sodium lamp

Q:How much is the LED street lamp and driving power 85W

Generally a dollar a W, warranty for three years.

Q:What are the characteristics of the development of LED street lamp intelligence?

Each lamp is installed street lamp intelligent control system can have an independent IP address, single lamp network can realize accurate location, remote control, operation state tracking and other functions, the effective management of public facilities, road traffic monitoring road. LED and big data, networking, cloud computing, communication technology and other advanced technology combine to enhance, to the city public safety management, and emergency response capabilities, which will bring more possibilities for the future development of LED.

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:Why does a LED street lighting system come with a phase light?

A phase line is already AC220

Q:High frequency jet lamp, LED lamp, xenon lamp, which is suitable for street lamps

Here to analyze the advantages and disadvantages of several light source: high pressure sodium lamp has high efficiency, long life, light penetration, rain and fog irradiation range is relatively secure, but a single color spectrum, low resolution, according to details of poor road.

Q:The design idea of LED intelligent energy-saving street lamp

Sound control is not recommended...The timing control circuit can be added in the driving power source to adjust the current supply of the LED light source to realize intelligent dimming.The advantages of this approach are relatively easy to implement and low cost.

Q:What are the components of the LED street lamp holder structure?

LED street lamp holder adopts aluminum alloy die-casting molding, it can effectively heat radiation and waterproof, dustproof.

Q:Solar street lamp, 60 watt LED lamp holder, with large battery

Total lighting time per night (temporarily indicated by H);60W the lamp cap is divided by the battery's rated voltage to draw the current (temporarily indicated by A)The number of days required for continuous wet days (temporarily indicated by T);Battery to prevent overcharge and over discharge, generally charged to 90%, discharge more than 20%, take 70% calculation, formula for:Battery capacity = 70% (A*H*T).

Q:What is the luminous flux of LED30W solar street lamps?

The luminous flux of LED light source is 1W 45mil 110lm to 130lm (this is a test at the rated 25 degrees at room temperature, in the actual application is certainly not to), regular 30wled products are a lens two with a light, even the best lens in there will be the loss of good, good quality of the lens, the loss in 10%, ordinary loss in more than 30, LED street common 30W are the traditional lamp type, the lamp outside and glass lens, the light loss is higher, so the comprehensive down than ordinary street lamp has a conventional calculation method is practical the luminous flux per lamp w lumens 0.7 is multiplied by the number of lamps, the luminous flux *0.6, luminous flux *0.75 good quality, this is probably the calculation method.
