The characteristics of the leds
- Aug 23, 2016 -
1, energy saving: white LED power consumption is only 1/10 of incandescent lamp, energy-saving lamp of a quarter.
2, long life: life is up to 100000 hours, for the average household lighting is "once and for all."
3, can work at high speed, energy-saving lamps, if frequent start on or off the filament will be black, quickly to fail, so more secure.
4, solid-state encapsulation, belongs to the cold light source type. So it is very good transportation and installation, can be in any tiny and closed equipment, not afraid of vibration.
5, led technology is in progress with each passing day, its luminous efficiency is astonishing breakthrough, the price has been reduced. A white LED into the family is rapidly coming of age.
6, environmental protection, no mercury harmful substances. LED bulbs assemblies can be very easy to tear open outfit, no manufacturers recycling can be recycled through other people.
7, with optical technology extends the LED point light source for the surface light source, increasing the shiny surface, eliminate the glare, sublimation visual effect, eliminate the visual fatigue.
8, lens and chimney integration design. Lens have concentrated and protection at the same time, to avoid the repetition and waste of light, make the product more concise and beautiful.
9, high power led plane cluster encapsulation, and the radiator and lamp holder design. Fully guarantee the led heat dissipation requirements and service life, basically meet the led any design of structure and the modelling of lamps and lanterns, led lamps and lanterns, extremely sharp features.
10 and significant energy saving. The super bright high-power led light source, with high efficiency power supply, than traditional incandescent lamp energy saving more than 80%, under the same power 10 times that of incandescent lamp brightness.
11, long life 50000 hours, more than 50 times that of the traditional tungsten filament lamp. LED by highly reliable advanced packaging technology - eutectic solder, fully guarantee long life of LED.
12, no stroboscopic. Pure dc, eliminating the traditional visual fatigue caused by light stroboscopic.
13, green environmental protection. Do not contain lead, mercury and other pollution elements, no pollution to the environment.
14, impact resistance, resistance to LeiLiJiang, no ultraviolet (UV) and infrared (IR) radiation. No filament and glass shell, there is no problem, the traditional tube rupture with no harm to human body, no radiation.
Work under 15, low thermal voltage, safe and reliable. The surface temperature of 60 ℃ or less (when environment temperature Ta = 25 ℃).
16, wide voltage range, universal LED lights. 85 v ~ 264 vac full voltage range constant current, ensure the brightness is not affected by voltage fluctuation and life.
17, using PWM constant current technology, high efficiency, low heat, high precision of constant current.
18, to reduce the line loss, for grid pollution-free. 0.9 or higher power factor, harmonic distortion 20% or less, EMI in line with the global index, reduced the energy loss of the power supply line and avoid the pollution to power grid of high frequency interference.
19, general standard lamp holder, it can directly replace halogen lamp, incandescent lamp, fluorescent lamp.
20, luminous efficiency rate can be as high as 80 lm/w, many kinds of LED lights WenKeXuan color, high color rendering index, good color rendering.
Obviously, as long as the cost of LED lights with the continuous improvement of LED technology. Energy-saving lamp and incandescent lamp must be replaced by LED lamps and lanterns.
Countries pay more and more attention to lighting energy saving and environmental protection, has been promoting the use of LED lamps and lanterns.
The advantages and disadvantages
* the cooling problem, if the poor heat dissipation significantly shortened life spans.
* low-end leds province electrical or lower than energy-saving lamps (cold cathode tube, CCFL).
* initial purchase cost is higher.
* for the LED light source directivity is very strong, need to consider the LED lamps and lanterns design special optical properties.
Neon lights and LED lights under the relevant comparison, to join the latest LED technology in comparison, not before you see the document in the network.
1. LED lights have a 100000 - hour life?
At 7% of the droop, actually only about 50000 hours. At 3% of the droop, practical application can reach 80000 hours.
2. The LED will not fever?
Will, need to heat dissipation.
3. The LED can replace incandescent bulbs?
Luminous flux, luminous efficacy and color rendering, but it's too expensive and will not decline in recent years. But the luminous flux can improve the product so as to reduce the cost of replacing incandescent lamp.
4. The LED can be used for ordinary light simply?
No, to drive power supply, optical LED lights and heat conduction.
5. Two kinds of light source properties and advantages
Advantage has been covered by the LED neon, but LED lights price is too high.
6. The power of the two kinds of light source
LED low voltage is good, but the load current is too large. Large particles of 1 watt LED single lamp input current ma in 350.
7. Two kinds of light source control technology
LED easy to implement, but mature neon lights.
8. The stability of the two kinds of light source
Inconsistencies, LED neon lights are quite stable. A few producers can do relatively stable, such as combined with AOD with CREE chip, take advantages of their chips.
9. Two kinds of light source price comparison
LED more expensive, but the yellow and red is, is the chief of your LED white light.
Outdoor use 10. Two kinds of light sources
Leds have been able to be completely waterproof, dustproof.
11. The comparison of two light source market
Global lighting products annual output value of $42 billion ($42 billion, China) LED light source is less than 1%
