LED energy saving features

- Aug 23, 2016 -

1. LED light source, high luminous efficiency

Luminous efficiency comparison: incandescent lights in 10 to 15 lm, halogen tungsten lighting effect for 12 to 24 lumens per watt, fluorescent lamp, 50-90 lumens per watt, sodium lamp, 90-90 lumens per watt, most of the electricity into heat loss.

LED lights, can be sent to a 50-200 lumens per watt, and glowing good monochromaticity, narrow spectrum, without filtering, can be directly emit colored visible light.

2. LED light source less power consumption

LED the single tube 0.03 to 0.06 watts, adopts dc drive, single tube driving voltage of 1.5-3.5 v. 15-18 ma reflect current speed, can be in high frequency operation, in under the condition of same illumination, power consumption is one over ten thousand of the incandescent lamp, fluorescent tubes, half of the Japanese estimates that if use 2 times higher than fluorescent lighting LED to replace half of Japan's incandescent lamp and fluorescent lamp, can save the equivalent of 6 billion litres of crude oil a year, the same effect of a more than 40 w fluorescent lamp, and use the power of each LED only 18 watts.

3. The LED light source long service life

Incandescent lamp, fluorescent lamp, halogen tungsten lamp is to use electronic field radiation emitting light, filament light easy to burn, thermal deposition, light attenuation characteristics, and USES the LED lamp is small volume, light weight, epoxy resin encapsulation, can withstand the high strength mechanical shock and vibration, invulnerability to breakage and the average life expectancy of 3-50000 hours, the service life of the LED lamps and lanterns of up to 3-5 years, can significantly reduce the maintenance cost of lamps and lanterns to avoid frequently changing light.

4. The safety and reliability

Low calorific value, no heat radiation, cold light source, can safely touch, can precisely control light type and light Angle, color and light, no glare, do not contain mercury, sodium and other substances may endanger health.

5. The LED light source is better for the environment

LED to full solid light source, impact resistance, not easily broken, waste recycling, no pollution to reduce a large number of harmful gases such as sulfur dioxide and nitrogen and carbon dioxide and other greenhouse gases produced to improve the environment and people's life can be called "green lighting light source."

Production of white LED technology at present, there are three types: a, by using the theory of three primary colors and have been able to produce red, green, blue three kinds of high brightness LED 3:1:6 mixing ratio of the light into a white, two, using the ultra high InGan blue leds, the tube always add a little yttrium drill pomegranate as the main body of the phosphor powder, it can be in blue light that inspired the yellow green, and the yellow green and white light blue synthesis and passes, three is an ultraviolet LED, using ultraviolet excitation tricolor phosphors or other phosphors, multicolor mixture of white light.

6. LED light source is more energy-saving

Energy-saving, of course, is the most main reason, we consider using the LED may have LED to more expensive than traditional light source, but take a year of energy recovery of investment of the light source to obtain 4-9 years energy-saving net cover periods of a few times a year.


Constant current source driving is the best way of LED driver, driven by constant current source, not in the output circuit in series current limiting resistor, LED on the flow of current is not affected by the outside power supply voltage, temperature changes, and the influence of LED parameter discreteness, thus can keep constant current, full play to all kinds of excellent properties of leds.

Using LED constant current power supply power to the LED lamps and lanterns, because working in the power supply during the current through the LED will automatically detect and control, therefore, need not worry in electricity instantly have a high current through the LED, without fear of load short circuit burn out the power supply.
