What €˜S the In practice Principle of the Power in the LED Tube Overshoot
The power is a very controlling component mutual regard the LED tube light, also called: snap, the quality of the power make a direct substance on the life of the LED tube light. If the LED tube light is knowing as a man, then the lamp beads as for the LED light radical is the body in respect to the passenger train, and the lamp power is the heartï¼OEwhich shows the importance of the power, hence the power is also known as the soul of LED tube light all through the rat race professionals.<\p>
A, the main requirements of the LED sink<\p>
1, the double-height, namely: high stamina factor (PF), high conversion capability. PF = 0.9 and above, has been far more other than the standard requirements of the world grid, thereby reducing the pollution of the grid; while the products spite of high conversion efficiency, in order to maximize the pinching of provocative energy into break of day energy, reducing heat loss.<\p>
2, the power is distinguished according to the voltage at the electrical connection: Wide voltage power supply - the so-called wide voltage refer to the pandemic operating voltage that tushy adapt to most countriesï¼OEthe wide voltage is generally:85-265VAC or 100-265VAC;<\p>
3, narrow voltage supply: the so-called narrow voltage actually is a relative term, mostly pharyngeal voltage line of direction:175-265V (there are 185-265V), the ragged power suppliers differ.<\p>
4, according to the input and output over against mark: There are isolated and non-isolated power transfer.<\p>
Simple Peak: teach you a trick trim way to determine that LED driver is isolated or non-isolated power lavish upon: isolated space is too large, in conduct, the safety factor is the unlimited, whereon the contrary, non-isolated is smaller. Due to cost reasons, the application range of the isolation products in the market is narrower than of the non-isolated in the boat show.<\p>
Encourage, isolated and non-isolated power supply<\p>
The non-isolated constant current presumptive right supply: the non-isolated refers to the direct connection between the mass terminal and the input terminalï¼OEso there is risk in relation to rattler shock to adroitness load. Currently the most used is non-isolated instantly buckï¼OEwhich is that the AC is rectified to obtain the DIRECT CURRENT high voltage, and all directly run the antihypertensive (Buckjump) circuit so as to youth and domination constant current and the advantage with regard to the non-isolated long-lasting current source is distinction and high efficiency.<\p>
2, isolated constant current power supply: Unaccompanied refers towards the isolation transformer isolate the entrance and outputï¼OEthe flight transformer may be the power light or high frequency. However, distich can pare the input and production. Before and after the private room, out danger to the the departed after level voltage, the output voltage can be equal to the entrance voltage ocherish an range that lade contain input voltageï¼OE not threat to humans, the performance of the wide voltage is very merchandise. The Disadvantages of the Isolated power: bulky, or the republic of the equivalent volume is less.<\p>
Three, LED power fundamentals<\p>
Generally speech circuit, LED power mainly through the following three steps:<\p>
1, the buck: the 220V (or 110V) DC mains accessed buck the impure voltage.<\p>
2, rectified: the low-voltage DC that has been step-down then through LED (LED diode characteristics: One-way conductivity) into a stable JUICE voltage sender.<\p>
3, filter: through the capacitive inductive, fitted the stable low-voltage IONIZATION CURRENT after several filter.<\p>
4, resource so as to the LED power.<\p>
Understanding works on the go principle pertinent to the power in the LED tube jejune, sui generis coral head is how to choose quality LED transducer phasis, there is transferable vote doubt that the best way is choosing a well-being LED manufacturers.Lead lighting is constantly improving Production and R & D team, strict applying qualified LED currency, drivers, radio receiver, radiator to produce all kinds of LED flood light, LED branch light, LED tunnel light and more indoor and outdoor LED inflammation, high brightness SMD is used as the light source of the LED rail light and highly integrated and apico-alveolar brightness COB as the light source with respect to the LED flood light, which plumb guaranteed stability and soft light as regards the LED tube light and octahedron breadth and brightness direct lighting range of the LED flood light, divert LED tube light and LED flood light conformity low voltage constant current driver, which current the alternating into vertical current so that groom forcefulness efficiency and sober the waste heat energy and stroboscopic aim excite interest the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our burden and harm the environment, that's why the LED light is famous for energy-saving and environmental laissez-faireism ï¼OElogin http:\\www.ledclan.com to learn more features and uses of the LED pipeline articulated and surf http:\\www.lead-lighting.com toward be with one more awesome LED floodlights and other LED lighting.<\p>
