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: What are the components of a LED street lamp?: Like traditional street lamps, the lamp post and support arm are requiredThe lamp is different with the traditional lamp, the main components of a LED light source, lamp shell (radiator), power supply.I can provide the light source and the power module

Q: Can the power supply for the LED street lamp be placed under the lamppost?: In fact, it is more convenient to put the driver into the electric door directly. If the later stage needs maintenance, it is not necessary to remove the whole lamp.

Q: What is the reason that the range of the LED100W street lamp is not enough or the brightness is not enough?: LED street lamp with the conventional high-pressure sodium street lamp is different, the light source of high power LED lamp with low voltage DC power supply, by the synthesis of GaN based blue LED and yellow fluorescent powder, white LED, with high efficiency, safety, energy saving, environmental protection, long life, fast response, high color rendering index unique advantages, can be widely used in city road lighting.

Q: How is the rated current of the LED street lamp holder?: The rated power of the lamp cap is divided by the input voltage and then divided by the power factor.

Q: Do 150wled street lights use much?: The lamp used in outdoor, to be waterproof and dustproof, so the lamp must be sealed, sealed lamps of water vapor temperature in extreme weather conditions more than 100 degrees, LED continuous work in such a high temperature environment, LED lights if the heat is not good, it is very easy to decay or bad lighting seriously.

Q: How much color temperature should be used for a LED street lamp?: 1. using high power LED chip and professional design, ensure that the LED of high efficiency, low light decay, long service life;2. 、 constant current drive switching power supply, wide voltage input, high power efficiency;3. start time is short, no strobe.

Q: Do constant current LED power supply for street lamp power supply? Is it better to use LED constant voltage power supply?: General is constant current power, street light is not clear, but 90% are constant current power.

Q: What is the reason for the low power factor of LED street lamp?: General LED is the switching power supply to drive, the switching power supply improve power factor method is to increase the power factor correction circuit, power factor correction circuit is generally more than 50W in order to play a role.

Q: What heat sink is best for LED street lamp radiator?: What is the external force of heat, force, that is to say, with the use of external heat, fan in the lamps or using superconducting tube, water-cooled, and so on, the advantage of active heat dissipation, efficiency has been improved, but the structure is complicated, the cost is increased, and the service life of the cooling equipment is generally not too long, less than 2 years is basically finished.

Q: What are the ways to save energy in street lamps?: The power consumption of street lighting also weakens the effect of landscape lighting on both sides of the road. Therefore, in accordance with the provisions in the design of "lighting design standard" City Road in luminance, uniformity of illuminance and combining the actual situation of site design, reasonable selection of light source, so as to meet the needs of the road and can meet the demand of average illumination, surface illumination uniformity requirements, maximize the utilization coefficient of lamps, in order to save the purpose of energy.
