LED lamp bead is a kind of light-emitting diode, which can convert electric energy into light energy semiconductor. It changes the principle of incandescent lamp tungsten light emission and energy-saving lamp three-base color powder illumination, and uses electric field illumination. LED lamps can be DC DC220V, no starter and ballast. The startup time is short and there is no flash frequency. The main features of LED lamps are:
1 New green environmental protection light source: LED uses cold light source, glare is small, no radiation, no harmful substances are produced during use. The LED has low operating voltage, adopts DC drive mode, ultra-low power consumption (single tube 0.03~0.06W), and the electro-optical power conversion is close to 100%, which is more than 80% energy saving than the traditional light source under the same lighting effect. LEDs have better environmental benefits, no ultraviolet and infrared rays in the spectrum, and waste can be recycled, no pollution, no mercury, and can be safely touched. It is a typical green lighting source.
2 long life: LED is a solid cold light source, epoxy resin package, anti-vibration, there is no loose part in the lamp body, there is no shortcomings such as filament light-emitting, heat deposition, light decay, etc. The service life can reach 60,000~100,000. Hours are more than 10 times the service life of traditional light sources. The LED performance is stable and can work normally in -30~+50oC environment.
3 multi-transformation: LED light source can use the three primary colors of red, green and blue. Under the control of computer technology, the three colors have 256 gray levels and can be mixed arbitrarily, which can produce 256X256X256 (ie 16777216) colors, forming different light colors. The combination. The color of the LED combination is varied, enabling a variety of dynamic changes and various images.
4 High-tech: Compared with the light-emitting effect of traditional light sources, LED light source is a low-voltage microelectronic product, which successfully combines computer technology, network communication technology, image processing technology and embedded control technology. The size of the chip used in the conventional LED lamp is 0.25 mm×0.25 nm, and the size of the LED for illumination is generally 1.0 mm×1.0 mm or more. The LED die-formed work-table structure, inverted pyramid structure, and flip-chip design can improve its luminous efficiency and emit more light. Innovations in LED package design include high-conductivity metal block substrates, flip-chip designs, and bare-plate cast leadframes. These methods can be used to design high-power, low-thermal resistance devices, and these devices have higher illumination than conventional LEDs. The illuminance of the product is greater.
