LED light source is a new type of light source. Let's see what advantages it has compared with traditional incandescent lamps.


1. Low power consumption of LED light source

LED single tube power is 0.03-0.06 W, DC drive is adopted, and single tube drive voltage is 1.5-3.5 v. The current is 15-18 Ma, with fast reflection speed. It can be operated at high frequency. When used with the same lighting effect, the power consumption is one tenth of that of incandescent lamps and one half of that of fluorescent tubes.


2. High luminous efficiency of LED light source

Comparison of luminous efficiency: the luminous efficiency of incandescent lamp and tungsten halogen lamp is 12-24 lumens / watt, that of fluorescent lamp is 50-70 lumens / watt, and that of sodium lamp is 90-140 lumens / watt. Most of the power consumption turns into heat loss.

LED luminous efficiency: it can emit 50-200 lumens / watt, and has good monochromaticity, narrow spectrum, and can directly emit colored visible light without filtering.


3. Strong safety and reliability of LED light source

Low calorific value, no thermal radiation, cold light source, safe touch, accurate control of light type, luminous angle, light color, no mercury, sodium and other substances that may endanger health.


4. Long service life of LED light source

Incandescent lamps, fluorescent lamps and halogen tungsten lamps are characterized by electronic light field radiation, easy burning of filament, thermal deposition and light attenuation. LED lamps are small in size, light in weight and encapsulated with epoxy resin, which can withstand high-strength mechanical impact and vibration and are not easy to break. The average service life of LED lamps can reach 100000 hours. The service life of LED lamps can reach 5-10 years, which can greatly reduce the maintenance cost of lamps and avoid the pain of changing lamps frequently.


5. LED light source is beneficial to environmental protection

LED is an all solid luminescent body, resistant to impact and not easy to break, recyclable waste, no pollution, reducing the generation of a large number of harmful gases such as sulfur dioxide and nitrogen compounds and greenhouse gases such as carbon dioxide, improving people's living environment, which can be called "green lighting source".
