LED bulbs , bulb and candle light similarities and buying guide
1.1 The origin of the bulb
Bulbs, Edison's incandescent usually called , glass , almost known, one hundred years of history , use very extensive. The principle is that through the power and shine , the tungsten filament is heated to incandescence ( above 2000 degrees ) , to generate light !
Peripheral made of glass bulb , the filament is maintained under vacuum or low pressure inert gas is to prevent oxidation of the filament to high temperatures , the lifespan of a modern incandescent about 1,000 hours . Although technically the measures taken hinder tungsten sublimation at high temperatures , but in fact can sublimate tungsten at high temperatures , from a solid directly into a gas . Hot then cold tungsten vapor condensation on the inner surface of the solid crystals attached Huawei lights . So black bulb will darken .
1.2 LED bulbs
Incandescent bulbs, cheap and easy to use , has proved to be a great success. While it was once the most popular indoor lighting , but it will eventually make way for more advanced technology , because it is not energy efficient. Decorative incandescent electric energy consumed , only 10% is converted into light , the rest becomes heat, wasted, high energy , and life is much , resource constraints in the global environment, governments are gradually being banned .
And fluorescent lamps, energy-saving lamps is often said , although compared to incandescent lamps , enhance the energy saving effect , but due to the use of heavy metals and many other environmental pollution, but also contrary to the trend of environmental protection , it is not the ideal source.
With the rapid development of LED technology , LED lighting gradually became the best new green lighting options . LED on the light emitting principle , energy saving, environmental protection level is far superior to traditional lighting products , LED bulbs also produced naturally !
1.3 Classification
LED bulbs, incandescent bulbs, according to the classification , mainly bulb, bulb and pull the tail tip bubble three.
1.4 Structure
A bulb is composed of six parts , lampshade , interfaces , LED light source , circuit boards , power supplies, light body ( radiator )
1 , Lamp beads : LED,
2 , Shade: PC with high transmittance material , light transmission rate up to 95% , good illumination uniformity , non-irritating to the eyes .
3, the cooling device: that is, light body , the lamp housing using Seiko Superior Aviation Aluminum lathing , heat and thermal conductivity . The use of hollow thermal design , increasing the thermal conductivity of the surface area of contact with the air , good heat dissipation.
4, the drive circuit : The first level is completely isolated chamber design, with overvoltage , overcurrent and short circuit protection , safe and reliable.
5 , Lamp Interface : for worldwide voltage , flexible replacement for the E27, E26, E14, B22 , such as different specifications lamp, easy to install.
6 , the circuit board
1.5 LED Advantage
1 , energy saving, energy LED white incandescent lamp 1/10 , energy-saving lamps 1/4; LED bulb energy savings have reached a very high level , in the case of the same luminous efficiency , energy consumption has down to the incandescent lamp 1 /8 and electronic energy-saving lamps 1/2. Significant energy saving. Ultra- bright LED light source , with high-efficiency power than traditional incandescent 80 % under the same power 10 times brighter than incandescent lamps ;
2 , longevity, life expectancy up to 100,000 hours , for ordinary home lighting can be described as " once and for all ." Long life of 50,000 hours, which is 50 times more than traditional incandescent light . LED high reliable advanced packaging technology - Eutectic Welding , fully guaranteed the LED long life ; energy-saving lamps , if you frequently start off quickly broken filament will be black .
3 , solid package, are cold-light source type. So it is very easy to transport and install , can be installed in any micro-and closed equipment , not afraid of vibration.
4 , no flicker . Pure DC work , eliminating the traditional visual fatigue caused by strobe light ;
5 , green. Does not contain lead , mercury and other pollution elements , no environmental pollution ;
6 , impact resistance, anti- Lei Lijiang , no ultraviolet (UV) and infrared (IR) radiation. No filament and glass enclosure, traditional lamp fragmentation problems , the human body without harm , no radiation.
7 , working under low thermal voltage , safe and reliable ; luminous efficiency of up to 90 Lm / w, various color temperature optional , CRI typically 0.76-0.85
1.6 Purpose
LED bulbs, including the bulb, candle bulbs , etc., in addition to the light source used for lighting lamps , but also widely used in shopping malls , office buildings, hotels, exhibition halls , conference rooms , hospitals , windows, home and other places , especially for high standards of luxury decorative lighting large spaces.
1.7 Conclusion
Bulbs, has a very broad market capacity and future development, and so will the development of the intelligent direction of these developments , in fact, are designed to meet people's needs !
