Development and design of LED lamps

LED lighting design knowledge, you know? Shenzhen LED lamp manufacturers Shenzhen mei'erte photoelectric Co., Ltd. below for you to explain in detail the LED lighting lamp of knowledge development and design.
With the improvement of LED packaging technology, LED industry is eager to break through the obstacles to replace the brightness, high brightness and high intensity discharge lamp (HID) or incandescent lamp.
Although LED has a cold and relatively high efficiency advantages, but the photothermal transduction pathway and traditional light, incandescent lamp heat generated in the optical path; LED light source heat is concentrated in the light path of the anti side, in the law of conservation of energy, the heat of LED design gradually become not to be ignored the problem.
Reduce the LED luminous efficiency
LED light from the semiconductor, electron hole binding energy produced during, so when the ambient temperature rises, the structure of electron and hole easily because the plateau itself vibrations increase, blocked or damaged, it will cause the reduction of LED light intensity.
The destruction of insulation
When the LED lighting design for heat dissipation caused by poor environmental temperature rises, as the insulating polymer material safety last line of defense, but also by the thermal degradation challenges.
General polymer material having thermoplastic, not in complete polymerization conditions, high temperature and humidity environment will promote the adverse reaction polymerization (i.e. cracking) are, in addition to produce deformation, will produce changes in characteristics, and even produce oxidation problem, insulating properties also suffer damage.
The above example, in no case of heat dissipation, heat accumulation of 100 watts, and in one hour he can heat water to a liter to nearly 100 degrees, so the high power LED lighting lamp challenge, not only in the heat from the LED light source is removed, it must be removed from the lamp, or long-term use after, is not only the lighting efficiency will decline, the lamp itself is security considered worthy.
In addition to used in street lamp, landscape, signal, indicating the fierce battle for lighting is LED.
Outdoor water with UV test LED lighting intensifies
The LED palette is other sources can not match advantage, so by the architecture and designers, the use of LED lamp has become a symbol of the city of advanced.
The function of moisture damage
Moisture accumulation, the biggest problem for electronic commodity function is to cause a short circuit and product. Although the pure water conductivity is low, but as long as added electrolyte, conductivity will increase, easy to cause a short circuit phenomenon. At the beginning of the short-circuit phenomenon with heated water evaporation and stop, come down for a long time, heat accumulation in electrolyte on the conductor electrifying plus, may damage the insulation material, resulting in the short circuit phenomenon permanent or loop corrosion.
The bare metal material such as solder joint or screw, the terminal will be the effect of the moisture rust. Once the occurrence of corrosion, resistance will increase, or expansion of the conductor may be connected to each other to produce short circuit, the danger of security (Figure 2). In addition some polymer materials by dehydration polymerization, were moisture existence will make the polymer decomposition reaction, resulting in failure of polymers.
LED lighting lamp above is the Shenzhen LED lamp manufacturers Shenzhen mei'erte photoelectric Limited company for you to explain the knowledge development and design.
MeiErTe photoelectric Limited company is located at Shenzhen Baoan Guangdong, committed to the development and production of LED energy-saving lamps, LED lighting species produced are: LED flood light, LED lamp, LED lamp, LED lamp, LED ceiling lamp, LED lamp, LED lamp, LED lamp, LED ball, bulb lamp, LED lamp, LED track light, LED lamp fittings etc.,
