led tube lights

When selecting the power supply circuit to bear than LED light about 20% of the total power, but also to ensure the maximization of the use of power life. What performance that LED power supply should have?In addition to conventional LED power protection features, it is best to increase LED temperature negative feedback in the constant current output, prevent LED temperature LED bulb is too high.High efficiency LED is energy-saving products, the drive power efficiency is high. The lamp structure of the power supply installed is particularly important. Because the LED luminous efficiency will decrease with LED temperature increases, so the LED heat dissipation is very important. High efficiency power supply, its power consumption is small, heat emitted in the fixture is small, it reduces the lamp temperature which is favorable for LED light failure delaying. High power factor and power factor is the specific load requirements in the electricity grid. Typically 70 watts or less appliances, there is no mandatory targets. Although a low-power single projecteur extérieur led electrical power factor has little impact on the grid, the night we lit, the same load is too concentrated, will produce more serious pollution on the grid. For the 30-watt and 40-watt LED driver power supply, it is said in the near future, maybe will have certain power factor index requirements. There are two kinds of common drive now: One constant voltage source for multiple constant current source, one constant current source for each channel individually to each LED power supply. In this way, the combination is flexible, when one channel LED fault does not affect other LED's work, but the cost will be slightly higher. Another species is a direct constant current power supply, LED is series or parallel operation. Its advantages are little low cost, but the flexibility is poor, but also need to solve the spot exterieur led problem that a LED failure does not affect other LED operation. These two forms exist in a period of time. Multi-channel constant current output power supply, in terms of cost and performance will be better. myledgrowupanty 141104

How to convert old bulb to LED bulb There is a great quantity of evidence pointing to the energy savings of LED bulbs but in contrast they do have a particularly high price tag. Another factor in their benefit is long life and high reliability so how do you evaluate whether they are worth purchasing? If you want to get a correct perspective on the GU10 LED Bulb commercials you need to work out the total cost of ownership and use of LED Bulbs and compare this to established incandescent light bulbs. The advent of 12-volt LEDs with bases designed to fit most 12-volt bulb-holders makes replacing 12-volt bulbs a realistic task for people with little or no electronic knowledge. Here, let’s find how to convert a 12V Bulb to a LED Bulb.1Switch on the power supply to locate the bulb and the wires supplying electricity to the bulb holder. Use a digital millimeter to establish which wire is positive and which is negative. Connect the positive and negative probes across the bulb holder. If the millimeter shows a positive reading, the positive probe is on the positive wire. A negative reading means the positive probe is attached to the negative wire. Mark or label the positive wire. Now switch off the E14 LED Bulb power.2Remove the bulb and place it somewhere safe. Check the polarity markings on the 12-volt LED. Insert the LED into the bulb-holder so the positive side of the LED connects with the positive side of the bulb holder. Push the LED firmly into the holder but do not use excessive force. 3Switch on the bulb. If you connected the LED correctly it will illuminate. If the LED does not illuminate, switch off the power, remove the LED, turn it through 180 degrees and reconnect it with the polarity reversed. Switch on the power and check again. anty881209wong 140305
