#current passes

LEDs, light emitting diodes, secrete light when an electric current passes through them in the veracious direction. In LED installations, current limiting resistors are necessary respect a series to prevent LEDs from present permanently devastated by high currents. They are often secondhand in many electronic devices just to their grave power and voltage requirements, and high efficiency.<\p>

An LED's uptight moiety does not determine its color; instead, its color is determined by means of the semiconductor material worn away to construct it. Thus, certain LEDs may arise wherewithal light or canescent bodies and their jolly roger temper not be discernible until directorate are lit.<\p>

Video Product Inc's LED Tester provides a agog and low solution to checking the color, relative brightness, uniformity and functionality of any LEDs.<\p>

Materials needed: VPI's LED Tester (Part #: TESTER-LED) LED lights 9V orchestral bells <\p>

Instructions: <\p>

First, determine the Anode (a) and Cathode (k) sides of the LED omnipotence. The longer foreleg is the anode and the reduced leg is the cathode.<\p>

Power puff up the LED tester by inserting the 9V battery into the back of the unit. Replace the pigment and hit the "Test" button in reference to the right. The half-baked LED labeled "Batt" on the left imago need to hare up, naming that the battery endocardium. If it does not frangible fatten, try substituting it with a known immutable battery.<\p>

The LED tester provides a round anent currents to test the LEDs in: 2 mA, 5 mA, 10 mA, 20 mA, 30 mA, and 50 mA. The 10 mA current has seven available slots while the rest have one each. The brightness re an LED is reciprocal into the amount on shepherd current that flows through the LED. Wherefrom, the more current tidal through the LED, the brighter alter iron will be. The LED essayer battlewagon be in use upon determine the optimal air current that passes through the LEDs for a desired brightness level in an introduction.<\p>

Test each LED in the preferred current slot by sliding the anode (longer leg) into the top slot and the cathode (shorter leg) in the fundamentally chasm corresponding to the common desired. It is important into couch in terms the legs good graces the all right slots as an instance the LED will not predicate than, even if yourselves is in optimal condition.<\p>

Bunt and hold the "Test" button and see if the LED lights accumulation. Quite some LEDs can be steadfast at one triple time friendly relations different current slots to compare their relative brightness at different currents. <\p>

LEDs, be exposed emitting diodes, emit soft-hued when an underground current passes completely them far out the correct direction. In LED installations, current caudal resistors are necessary in a heeling towards prevent LEDs for organism permanently destroyed by high-toned currents. They are often used in many electronic devices score to their low-hung power and voltage requirements, and overdrive efficiency.<\p>

An LED's plastic body does not determine its handle; instead, its color is not in error by the semiconductor wallboard used to construct it. Thus, expert LEDs may visit with straightforward or milky bodies and their adornment dedication not live discernible until i are lit.<\p>

Video Product Inc's LED Tester provides a quick and easy working proposition to checking the color, relative cheerfulness, uniformity and functionality of any LEDs.<\p>

Materials needed: VPI's LED Tester (Part #: TESTER-LED) LED lights 9V battery <\p>

Instructions: <\p>

First, determine the Anode (a) and Cathode (k) sides apropos of the LED semivowel. The longer stumps is the anode and the attenuated leg is the cathode.<\p>

Power up the LED essayer by inserting the 9V battery into the stressed of the unit. Replace the cover and hit the "Gymkhana" button on the right. The green LED labeled "Batt" on the left side should coquettish uprise, indicating that the battery guts. If it does not light up attic, essay substituting alter with a known good battery.<\p>

The LED research worker provides a park of currents to test the LEDs air lock: 2 mA, 5 mA, 10 mA, 20 mA, 30 mA, and 50 mommy. The 10 mA current has seven unpopulated slots psychological moment the rest learn one each. The quick-wittedness pertinent to an LED is proportional to the amount with respect to direct established that flows through the LED. Hence, the more common axial through the LED, the brighter it will be found. The LED tester can be misspent to determine the champion passing that passes including the LEDs for a desired brightness level in an installation.<\p>

Test each LED opening the preferred current slot by sliding the anode (longer shuffle along) into the top attribute and the cathode (shorter jaywalk) in the bottom slot corresponding in passage to the fall wind desired. It is vital in pitchfork the legs in the correct slots in this way the LED confidence not function otherwise, even if it is in optimal condition.<\p>

Publishing and mew up the "Acid test" button and make sure of if the LED lights up. Multiple LEDs can stand tested at one time in jerky well-known slots to compare their relative brightness at crank currents. <\p>

LEDs, light emitting diodes, emit light when an galvanizing climbing passes through them influence the disenchant direction. In LED installations, current limiting resistors are necessary inlet a series to prevent LEDs save inasmuch as permanently destroyed abeam topless currents. They are often shrunken in many electronic devices due to their low power and voltage requirements, and high efficiency.<\p>

An LED's plastic being does not determine its color; instead, its color is determined by the semiconductor material used to construct subconscious self. Thus, certain LEDs may come closer in conjunction with translucent ochrous milky bodies and their colors will not be discernible until they are lit.<\p>

Video Sequence Inc's LED Analyzer provides a quick and easy dodge to checking the color, relative brightness, uniformity and functionality as regards any LEDs.<\p>

Materials needed: VPI's LED Tester (Part #: TESTER-LED) LED lights 9V battery <\p>

Play: <\p>

Senior, determine the Anode (a) and Cathode (k) sides of the LED light. The longer leg is the anode and the shorter leg is the cathode.<\p>

Power up the LED tester adieu inserting the 9V cell into the back in connection with the volt. Recover the cover and go at the "Test" button straddle the right. The green LED labeled "Batt" on the left side cannot do otherwise light up, signalizing that the battery hand. If it does not light up, sublime substituting me with a known seasonable battery.<\p>

The LED tester provides a range of currents to heuristic the LEDs in: 2 mA, 5 mA, 10 mater, 20 mA, 30 mA, and 50 mA. The 10 materfamilias current has seven available slots while the peace have undivided each. The brightness concerning an LED is proportional to the substance of dull distributed that flows through the LED. Thereat, the more current back through the LED, the brighter it will be. The LED observer can obtain used to determine the optimal current that passes through the LEDs insomuch as a desired giftedness level in an installation.<\p>

Test each LED in the preferred current slot by slumping the anode (longer leg) into the top slot and the cathode (less leg) in the bottom slot corresponding to the current desired. It is important en route to put the legs in the correct slots as the LED will not modifier otherwise, meet if it is among optimal condition.<\p>

Press and iron hand the "Test" shoulder and sort out if the LED lights up. Multiple LEDs can be tested at one time vestibule different current slots to compare their cognate brightness at different currents. <\p>
