Principle of LED desk lamp light source

Main parameters of LED desk lamp LED light work is VF, IF other related is color/color/wavelength/brightness/light Angle/efficiency/power consumption, etc. LED is a PN junction diode, only enough positive voltage applied to the conduction current, VF forward voltage is established for LED a normal working state, the IF forward current is LED, luminous intensity and the flow of electric current into a direct ratio. White LED VF nominal voltage: 3. 4V± 0. 2V。 LED light source in mass production, each batch of leds VF has certain discreteness, consistency, necessary for the customers to use when the LED factory must be sold by different VF step; Otherwise it will lead to the same production there are differences between the luminance of LED lamps and lanterns; LED the IF, according to the application needs to choose different current class cannot mix.

The manufacture marketing game of lamp holder socket is changing with each innovation, and businesses of all products need to be ready to pounce.

The guiding vision of Chaozhou Guangli Electronie Factory is 'Bringing the best to everyone we touch'. By 'The best', we mean the best products, the best people and the best ideas.

Chaozhou Guangli Electronie Factory deems night light lamp as evolutionary rather than revolutionary. We've always had these 'social commerce' marketplaces in some form.
