The working characteristics of LED light source

Characteristics of the LED light source: LED lighting light source VF voltage is very low, generally VF = 2. 75 - 3. 8 v, IF in 15 1400mA； So the output voltage of the LED driver IC is VF X N/VF X 1, IF constant current in 15 1400mA。 LED lamps using LED light source with low power ( 如果= 15 - 20mA) And high-power



the LED light source' LED light source is the light emitting diode ( 领导) For light source of light. 】 Characteristics:

lighting of the LED light source VF voltage is very low, generally VF = 2. 75 - 3. 8 v, IF in 15 1400mA； So the LED driver IC 【 In recent years, mobile phones, digital cameras, portable electronic products such as LCD mostly use color panel, liquid crystal display itself belongs to the initiative luminous element must use the backlight module lighting was able to read the panel image. 】 The output voltage is VF X N/VF X 1, IF constant current in 15 1400mA。 LED lamps using LED light source with low power ( 如果= 15 - 20mA) And high power ( 如果马> 200) ) More than two kinds, small power LED for the LED fluorescent lamp, chandeliers, grille lamp' With the development of the grille lamp, the decorate according to the needs of the customers and designers, can be divided into dark outfit with with the two styles. 】 ； High power LED' High power LED refers to the light emitting diode with large rated power. 】 Used for home lighting, lamp, underwater light, wash wall lamp, street light, tunnel lamp, automobile work light, etc. Power LED light source is driven low voltage, large current device, its luminous intensity is determined by the size of the current through the LED, too strong electricity will cause LED light attenuation, too weak electricity will affect the LED luminous intensity, therefore, the LED driver needs to provide constant current power supply, to ensure the safety of high power leds used, at the same time to achieve the ideal of luminous intensity. In the LED lighting' 领导( LightingEmittingDiode) That is led lighting, lighting is a solid light-emitting semiconductor devices. 】 Areas, to embody the characteristics of energy saving and long life, choose a good LED driver IC is critical, without a good driver IC match, the advantages of LED lighting can't reflect.

LED green lighting LED driver chip to the development of innovation design, the LED lighting lamps and lanterns is inseparable from the drive of the chip, so you need a variety of functions of LED light source driver IC. LED lamps and lanterns chooses 36 v ac power can be considered under the isolation power supply, such as choosing 220 v and 100 v ac power isolation power supply should be considered.
