In the field of LED lighting, in order to reflect the characteristics of energy saving and long life of LED lamps, the correct choice of LED driver IC is essential. Without good driver IC matching, the advantages of LED lighting cannot be reflected. So when choosing LED driver IC, what performance indicators and methods should be paid attention to?
LED lighting has developed rapidly in the near future, and LED has been widely recognized as a green and clean light source. LED light source has long service life, energy saving, simple and convenient application, and low cost. Therefore, it will be widely used in home lighting. According to a survey conducted by Osram Opto Semiconductors in 2008, the global annual shipment of home lighting sockets is about 50 billion.
The technology of LED light source is becoming more and more mature, and the lumens per watt are growing rapidly, prompting it to reduce prices year by year. Taking the 1W LED light source as an example, the price in the spring of 2008 was one-third of the price in the spring of 2006, and the price in the spring of 2009 will be reduced to a quarter of that in 2006.
The massive market of LED green lamps and the continued steady growth in demand for several years will be the super tsunami in the consumer electronics market after the VCD, DVD, mobile phones and MP3 in the integrated circuit industry!
The superior performance of LED lamps with high energy saving, long life, and environmental protection is widely recognized.
1. High LED energy saving: DC drive, ultra-low power consumption (single tube 0.03 ~ 1W) electro-optic power conversion is close to 100%, the same lighting effect is more than 80% energy saving than traditional light sources.
2. Long-life LED: LED light source is called long-life lamp. Solid cold light source, epoxy resin encapsulation, no loose parts in the lamp body, there are no shortcomings such as filament burning easily, thermal deposition, fast light decay, etc. The service life can reach 50,000 to 100,000 hours, which is 10 years longer than the traditional light source More than times.
3. LED is environmentally friendly: LED is a green light source with better environmental protection benefits. There is no ultraviolet and infrared rays in the spectrum, low heat, no strobe, no radiation, and waste can be recycled, no pollution does not contain mercury, cold light source, can be safely touched, it is a typical green lighting source.
Working characteristics of LED light source
The VF voltage of the LED light source for lighting is very low, generally 2.75 ~ 3.8V, IF is generally 15 ~ 1,400mA. Therefore, the output voltage of the LED driver IC is VFxN or VFx1, and the IF maintains a constant current of 15 to 1,400 mA. There are two types of LED light sources used in LED lamps: low power (IF is 15 ~ 20mA) and high power (IF is greater than 200mA). Low-power LEDs are mostly used to make LED fluorescent lamps, decorative lamps and grille lamps. High-power LEDs are used for home lighting, spotlights, underwater lights, wall washer lights, street lights, tunnel lights, car work lights, etc. The power LED light source is a device driven by low voltage and large current, and its luminous intensity is determined by the current flowing through the LED. Excessive current will cause LED light attenuation, too small current will affect the luminous intensity of LED. Therefore, the LED driver needs to provide a constant current power supply to ensure the safety of high-power LEDs, while achieving the desired luminous intensity. In the field of LED lighting, in order to reflect the characteristics of energy saving and long life of LED lamps, the correct choice of LED driver IC is essential. Without good driver IC matching, the advantages of LED lighting cannot be reflected.
Microphone:
Microphone is a kind of electrets microphone unit for audio input. It is a transducer which can transduce audio signal into electric signal. It is also called receiver. It is widely used in many industries which need audio input.
Our main microphones include:
1) From the diameter: we have microphones in 4mm~10mm.
2) From the direction, we have omni-direactional and one-directional micphones.
