The present application is related to a lighting apparatus and more particularly related to a lighting apparatus with nice heat dissipation capability.
Electroluminescence, an optical and electrical phenomenon, was discover in 1907. Electroluminescence refers the process when a material emits light when a passage of an electric field or current occurs. LED stands for light-emitting diode. The very first LED was reported being created in 1927 by a Russian inventor. During decades' development, the first practical LED was found in 1961, and was issued patent by the U.S. patent office in 1962. In the second half of 1962, the first commercial LED product emitting low-intensity infrared light was introduced. The first visible-spectrum LED, which limited to red, was then developed in 1962.
After the invention of LEDs, the neon indicator and incandescent lamps are gradually replaced. However, the cost of initial commercial LEDs was extremely high, making them rare to be applied for practical use. Also, LEDs only illuminated red light at early stage. The brightness of the light only could be used as indicator for it was too dark to illuminate an area. Unlike modern LEDs which are bound in transparent plastic cases, LEDs in early stage were packed in metal cases.
With high light output, LEDs are available across the visible, infrared wavelengths, and ultraviolet lighting fixtures. Recently, there is a high-output white light LED. And this kind of high-output white light LEDs are suitable for room and outdoor area lighting. Having led to new displays and sensors, LEDs are now be used in advertising, traffic signals, medical devices, camera flashes, lighted wallpaper, aviation lighting, horticultural grow lights, and automotive headlamps. Also, they are used in cellphones to show messages.
A Fluorescent lamp refers to a gas-discharge lamps. The invention of fluorescent lamps, which are also called fluorescent tubes, can be traced back to hundreds of years ago. Being invented by Thomas Edison in 1896, fluorescent lamps used calcium tungstate as the substance to fluoresce then. In 1939, they were firstly introduced to the market as commercial products with variety of types.
In a fluorescent lamp tube, there is a mix of mercury vapor, xenon, argon, and neon, or krypton. A fluorescent coating coats on the inner wall of the lamp. The fluorescent coating is made of blends of rare-earth phosphor and metallic salts. Normally, the electrodes of the lamp comprise coiled tungsten. The electrodes are also coated with strontium, calcium oxides and barium. An internal opaque reflector can be found in some fluorescent lamps. Normally, the shape of the light tubes is straight. Sometimes, the light tubes are made circle for special usages. Also, u-shaped tubes are seen to provide light for more compact areas.
Because there is mercury in fluorescent lamps, it is likely that the mercury contaminates the environment after the lamps are broken. Electromagnetic ballasts in fluorescent lamps are capable of producing buzzing mouse. Radio frequency interference is likely to be made by old fluorescent lamps. The operation of fluorescent lamps requires specific temperature, which is best around room temperature. If the lamps are placed in places with too low or high temperature, the efficacy of the lamps decreases.
In real lighting device design, details are critical no matter how small they appear. For example, to fix two components together conveniently usually brings large technical effect in the field of light device particularly when any such design involves a very large number of products to be sold around the world.
