LED (Light EmitTIng Diode) is different from the traditional tungsten lamp light source because of its light-emitting principle. It uses the PN junction potential difference of the diode to generate a point light source. It is also called a solid-state light source because of its structural characteristics. Due to the low-energy driving characteristics of LEDs and the granular components are easy to set up in any shape of vehicles, LED heat dissipation and optical lens processing have been developed to make the point light source characteristics of LEDs closer to the familiar traditional light source performance. On the topic of power saving and energy saving, it rushed into the home lighting market. ..
Existing LED production technology, the lumens produced by a single component still have a clear application gap with commonly used tungsten filament lamps. Therefore, LEDs are still mostly used in LCD TV and Tablet PC backlight applications. In addition, at low brightness Because of the non-lighting purpose, the LED strip lights in the situation of the user will not require too much for its lighting effect, and it is also a large number of LED use occasions.
To enlarge LED bulb products, it is necessary to install a switching power supply, temperature control circuit, active cooling fan drive circuit, etc. in a limited space, and the space is highly challenging.
In order to achieve the equivalent traditional light source and become an alternative environment-friendly light source, LED lighting has become a key technical breakthrough point for the brightness of its light source. At present, even the brightest mass-production products, single components The brightness is still unable to achieve the replacement effect, and it must emit light through several or dozens of parallel connections in order to achieve the lighting effect close to the traditional light source.
Efficiency, environmental protection issues LED light source application is gradually paid attention to
Observe the daily lighting sources, incandescent lamps based on tungsten filament lamps, and compact fluorescent lamps (CFL) based on gas discharge luminescence. The incandescent lamp produces high-heat light emission by heating the tungsten filament. In terms of physical characteristics, it will cause a serious loss of efficiency due to high heat, and its luminous energy is mostly wasted in the form of heat.
Although fluorescent lamps use high-frequency gas discharge to produce luminous effects, even if they perform very well in terms of energy saving, in order to make fluorescent lamps, mercury vapors that are harmful to the environment must be injected into the lamp tube. Even more dangerous, because there are mercury vapor and fluorescent powder in the lamp tube, and poor quality products will also have ultraviolet problems. Under the increasing environmental protection demands, fluorescent lamps are definitely not the best light source choice.
Because the solid-state LED lighting technology is different from traditional light sources, the production, use and recycling are more environmentally friendly. However, early LED light sources were mostly used in signal lights and indicator lights for medium / low brightness and low power applications, and there was no heat dissipation in the development process. The problem is that in order to develop "lighting" applications, LED components must achieve high brightness, and due to the light-emitting plateau, their high operating temperature is concentrated at a single point, and more energy must be spent on heat treatment to design.
