FAQ of LED Street Light Maximizing Energy Savings

*Why do LEDs have a higher initial cost than conventional light sources?

LEDs are made of electronic components which need to be packaged together to offer long lasting efficient light sources to the end user. Apart from the LED chip itself which has sapphire and gallium in the semiconductor, the process of packaging with materials like ceramic, rare earth phosphors, silicone, solder and gold wire add to the overall cost. White LEDs require further tests for calibration and standardisation.

*What are the economic advantages of using LEDs over conventional light sources?

Although the initial cost of conventional light sources is less than LEDs, they do not take into account the operational and maintenance cost of the lighting system. LEDs, having a longer life , reduce maintenance and lamp replacement cost. This reduces cost of labour to replace lamps and the cost of new lamps at the end of lamp life cycle. LEDs, also consume less energy. Thus the overall cost of a LED system can thus be significantly lower than conventional lighting systems. Most applications with LEDs offer a payback period as low as 3-4 years.

*What are the strategies in the development of LED technology that are helping to reduce the cost of LEDs in the future?

Some of the strategies reducing the cost of LEDs in the future are:

Reduction in the production process.

Simplification and reduction in the number of components.

Introduction of new materials.

Q:Is the price of the street lamp factory in led the same?: The price of street lamps at the LED street lamp factory is the same as that of the foreign ones. LED street lamp external price = cost + profit. The cost is fixed, that is, profits will change, in addition to street lamps manufacturers require profits, the salesman will be appropriate adjustments, this depends on the salesman personally

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 to determine the power of LED street light?: Because this situation does not see the chip surface, so it can only be estimated(attention: eundong Street)Supplement:LED street lamp power LED street lamp power and rural branch city road has no clear standard, but in general: LED lamp power city road about 80W-250W LED Street Village Branch power about 30W120W.

Q:What are the main uses of LED street lamps?: Street lights must be used on highways, such as roads, highways, urban roads, parks and so on

Q:Road light is one of LED. How much is it?: You can have a look at the light path. It's nice and the price is right

Q:Where are the batteries located in the installation of solar street lamps? Buried?: Generally, the ambient temperature is normal between minus 30 and 60 degrees, and there's no need to keep the battery stable before you bury it!

Q:How to select suitable driving power for LED street lamp: LED lamp driving power supply for outdoor work, poor environment, the temperature variation of four seasons a year, the summer sun, winter cold, but also accept the rainstorm, lightning shock, so all kinds of tolerance need to be considered.

Q:What is the actual service life of the LED street lamp?: In good heat dissipation, rated current work, with constant flow drive, high quality LED life up to 50 thousand small season

Q:Why does fog cause fog when the LED street lamp is aging?: The outside gas is in, and it's designed to be self breathing.

Q:What is the luminous flux of LED30W solar street lamps?: High power LED street lamp has a long service life, and the light source life is over 50000 hours. It is 5~10 times of traditional lamp. The LED light source adopts the most advanced white 1W package, the surface bonding is welded on the 2mm thick aluminum based circuit board, and then the aluminum substrate is installed on the radiator plane to ensure the rapid heat transfer to the radiator. In addition the radiator and lamp shell integration design, fully guarantee the LED cooling requirements and service life. Advanced packaging technology to ensure high reliability of LED, good heat dissipation to ensure that LED work at the allowable temperature, the combination of the two, fully guarantee the long service life of LED.
