Ten years later, LED will be the mainstream lighting industry

It was also predicted that the future LED life limit will be infinite. Most people think that energy-saving lamps can be energy saving 4/5 is a great pioneering work, but the LED fluorescent lamp is also more energy-efficient than energy-saving lamps 1/4, which is a solid light source greater reform. In addition, LED also has other advantages, high light quality, basically no radiation, is a typical green lighting source, reliable and durable, low maintenance costs, etc..

Energy saving: the spectrum of LED is almost all concentrated in the visible band, and the luminous efficiency can reach 80 - 90%. The LED and the ordinary incandescent lamp, energy-saving lamps and T5 three spiral fluorescent lamp has made a comparison, results show that the optical efficiency of ordinary incandescent lamp life is 12lm/w, less than 2000 hours, the light effect of spiral energy-saving lamp for 60lm/w, life expectancy of less than 8000 hours, T5 fluorescent lamp is 96Alm/ w, life for about 10000 hours, white LED and 5 mm in diameter is 20 ~ 28lm/w, life can be more than 100000 hours. It was also predicted that the future LED life limit will be infinite. Most people think that energy-saving lamps can be energy saving 4/5 is a great pioneering work, but the LED fluorescent lamp is also more energy-efficient than energy-saving lamps 1/4, which is a solid light source greater reform. In addition, LED also has other advantages, high light quality, basically no radiation, is a typical green lighting source, reliable and durable, low maintenance costs, etc.. Because LED has more than other solid light source can not match the characteristics of 10 years after the LED lighting industry will be the main source of light.

(two) safety and environmental protection: LED working voltage is low, more than 1.4 - 3V; ordinary LED working current is only 10mA, the high brightness is also 1A. LED in the production process do not add "Mercury", do not need to inflate, do not need a glass shell, good impact resistance, good seismic resistance, not easy to break, easy to transport, very environmentally friendly, known as "green energy".

(three) long service life: LED small size, light weight, the shell is epoxy resin package, not only can protect the internal chip, but also has the ability to light gathering. LED service life is generally between 50 thousand - 100 thousand hours, because LED is a semiconductor device, even if the frequent switch, it will not affect the service life. At present, the main use of domestic lighting is incandescent lamp, fluorescent lamp and energy-saving fluorescent lamp.

(four) fast response: LED frequency response of F tau and injected minority carrier lifetime tau MC, such as GaAs material LED, the tau MC general in the range of 1 - 10ns, the response frequency is about 16 160MHz, so the high frequency response for the 6.5MHz to display the video signal that has been enough, this is one of the key factors to realize large screen video LED. Currently, the LED response time has reached a minimum of 1 microseconds, generally more than a few milliseconds, about ordinary light response time of 1/100. Therefore, the utility model can be used for a plurality of high frequency environments, such as an automobile brake lamp or a state lamp, which can shorten the braking time of the vehicle after the vehicle, thereby improving the safety.

(five) high luminous efficiency: incandescent lamp, halogen lamp light effect of 12 - 24lm/w (lumen / watt), fluorescent light effect of - 70lm/w, sodium lamp light efficiency of 90 - 140lm/w, most of the power consumption into heat loss. And the light effect of LED can be improved by 50 - 200lm/w, and the light is good, the spectrum is narrow, without filtering can be issued directly colored visible light.

(six) the small size of the LED element: it is more convenient for the arrangement and design of all kinds of equipment, and can better realize the effect of "see the light not to see the light" in the night light.

(seven) LED light energy concentration is high: concentrated in the smaller wavelength window, high purity.

(eight) the LED light emitting intensity is strong: the brightness attenuation is much lower than the traditional light source.

(nine) LED low voltage direct current can be driven: it has the advantages of small load and weak interference.

(ten) it is possible to control the composition of luminescence spectrum, so that it can be used for local or key lighting in museums and galleries.

(eleven) can control the semiconductor light emitting layer, the size of the width of forbidden band semiconductor materials: thus emit different colors of light, and high chroma.

(twelve) high color rendering: no harm to human eyes.
