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:LED good or low frequency electrodeless lamp?: LED is the light produced by hole migration. Electrodeless lamp is an electromagnetic field to excite gas particles. Judging from the current technology, LED is not mature, so electrodeless lamp is better

Q:What is the voltage of the street lamp? What about LED?: LED are generally DC voltage, a wide variety of categories: such as the common 12V-24V, 1.8~3.8V, special 220VAC.

Q:How much is the LED street lamp and driving power 85W: Generally a dollar a W, warranty for three years.

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.

Q:Where can I buy LED street lamp and aluminum alloy shell, what's the quality of the product? Who can provide?: Advantage1, the lamp adopts Aluminum Alloy die-casting molding, can be effective in cooling and waterproof and dustproof. The surface of the lamp has been treated with UV resistance and corrosion resistance, and the overall lamp meets the IP65 standard;2, no bad glare, no strobe. The glare, visual fatigue and sight interference caused by the general glare of the street lamp are eliminated, and the driving safety is improved;3, the radiator and lamp shell integration design, the LED is closely connected with the shell, the shell wing and the air convection heat, and fully guarantee the LED lamp life.4, the single ellipse reflecting cavity is designed with the spherical isolated surface, the light emitted by the LED is controlled in the required range, and the uniformity of the luminous effect of the lamp and the utilization ratio of the light energy are improved.5, the number of chips per unit area can be flexibly designed and can be packaged into different point light sources or surface light sources as needed6, through different combinations can adapt to different voltage and current, adapt to the drive design, so as to improve the overall light efficiency

Q:How much is the LED terminal voltage of the solar street light controller v?: General digging machine LED terminal voltage, 12V, 24V, 36V, street lights 36V more.

Q:What are the parts of a LED street lamp?: Solar energy is one of the most direct the most clean energy, solar energy is a huge amount of renewable energy, each day to reach the earth's surface radiation can be approximately equal to 2.5 millions of barrels of oil, can be said to be inexhaustible. The LED spectra of almost all concentrated in the visible light spectrum, so high luminous efficiency, is generally believed that energy-saving lamp energy-saving 4/5 is a great initiative, but also energy-saving energy-saving lamp LED than 1/4, this is a great reform of solid light source. Solar LED lighting integrates the advantages of solar energy and LED.

Q:How is the glare of a LED street lamp solved?: You need to work on the LED drive to shorten the PWM cycle until you don't feel the glare when you're moving fast.

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:Please use LED lamp beads with other lamp beads is not the same?: With 3030 beads, if you want to add a more bright lens, of course, the cost is relatively high. Now do lamp manufacturers, a large price gap. Note: "can see Taiwan billion light 3030 beads, than domestic good, the price gap is not too, the focus is really practical. But Taiwan billion light bulbs are produced in Taiwan, by the domestic certified dealer agent.
