Solar-powered LED into new ways of building energy efficiency
Solar photovoltaic power generation system has been a lot of years, but due to the high initial investment in architectural lighting systems have not been widely used. With the rapid development of the technology of light-emitting diode, especially white light diode efficiency characteristics, solar photovoltaic power generation system with LED lights combined with the lighting system will be the new way of building lighting buy led bulbs energy saving
As the second largest energy consumer in the world, the Chinese government has always attached great importance to energy and energy conservation, as early as in the early 1980s on the proposed energy development and conservation both conservation priority position "approach into national energy efficiency economic and social development plans. Solve China's energy problem, on the one hand, to increase revenue, increase domestic energy exploration and development efforts; the other hand, throttle, must adhere to conservation priority environmental, dramatically improve energy efficiency, accelerate the construction of a conservation-oriented society.
50s of the last century, the Bell Laboratories in the United States for the first time made practical monocrystalline silicon solar cells, the birth of the solar energy led tube manufacturer is converted to electricity utility photovoltaic technology. The solar cell working principle is based on a semiconductor PN junction of the photovoltaic effect, that is, when the object is illuminated, the state changes of the charge distribution within the object to produce an effect of the emf and current. I.e. when sunlight or other light irradiation semiconductor PN junction, it will appear on both sides of the PN junction of the voltage, called photovoltage, so that a short circuit of the PN junction , will generate electricity.
Photovoltaics refers directly without going through a thermal process light energy into electrical energy power generation. It includes a photovoltaic power generation, photochemical generation light perception should power generation and optical biomass generation. PV is the use of solar and semiconductor electronic device to effectively absorb solar radiation, direct power generation methods and transformed into electrical energy, is today the mainstream of the solar power generation. Nowadays, it is commonly referred to as solar power generation solar photovoltaic power generation ( PV ), also known as solar cell power generation.
In recent years, solid-state lighting has been rapid development. The solid state lighting means all solid hair light emitting device as a light source lighting technology, mainly containing semiconductor lighting a light emitting diode ( mr16 led bulbs ) and organic light-emitting diode ( OLED ). LED lamp as a light source, and its advantages are: high photoelectric conversion efficiency, low voltage power supply, long service life, we can choose to issue monochromatic light can efficiently emit white light, so can greatly save energy. The semiconductor light emitting diode (LED) using the minority carrier injection PN junction with the majority carrier compound, thereby to emit visible light, is a direct electrical energy into light energy emitting devices. The structure of the light emitting diode by the PN junction chip, electrodes and optical system. When After signing forward bias on the electrode, so that electrons and holes are injected to the P and N regions, when the non-equilibrium minority charge carriers when combined with the majority carriers, the radiation photons in the form of excess energy into light energy. The light-emitting process includes three parts; under forward bias of the carrier injection, the composite radiation and energy transfer. Light-emitting diodes have many advantages: low voltage, low power consumption; stable performance, and long life (typically of 10 million to 10 million h); impact resistance, vibration resistance;, light weight, small size, and low cost.
