Why tube light is more laite?

ANS:

Inakyanadesenta (Incandescent) balbe , in light of the pracinatama invention , a coil of thin wire ( filament ) , and through which electricity flows . This is due to the thin wire filament heated protest from around the light spreads . However, most of the electricity is turned into heat and little light . Fluorescent (Fluorescent) Light Tube works differently . The inner part of the tube is covered by a type of fluorescent material . Although both ends of the tube filaments , and gas emissions it produces light . The electricity flows from one end to the other end of the moisture through the mercury , which emits ultraviolet light . This ultraviolet light and visible light to excite fluorescent astaranake created . Since you do not need to be heated , so most of the light is turned into laite tube , 40- watt fluorescent tubes , even more than a 100 watt light bulbs inakyanadesenta created , so the electricity savings.

Circuit Notes

Any number of normally open switches may be used. Fit the mercury switches so that they close when the steering is moved or when the bike is lifted off its side-stand or pushed forward off its centre-stand. Use micro-switches to protect removable panels and the lids of panniers etc. While at least one switch remains closed, the siren will sound. About two minutes after the switches have been opened again, the alarm will reset. How long it takes to switch off depends on the characteristics of the actual components used. But, up to a point, you can adjust the time to suit your requirements by changing the value of C1.

The circuit board and switches must be protected from the elements. Dampness or condensation will cause malfunction. Without its terminal blocks, the board is small. Ideally, you should try to find a siren with enough spare space inside to accommodate it. Fit a 1-amp in-line fuse close to the power source. This protects the wiring. Instead of using a key-switch you can use a hidden switch; or you could use the normally closed contacts of a small relay. Wire the relay coil so that it is energized while the ignition is on. Then every time you turn the ignition off, the alarm will set itself.

When it's not sounding, the circuit uses virtually no current. This should make it useful in other circumstances. For example, powered by dry batteries and with the relay and siren voltages to suit, it could be fitted inside a computer or anything else that's in danger of being picked up and carried away. The low standby current and automatic reset means that for this sort of application an external on/off switch may not be necessary.
 

Mini variable power supply

T1 steps down AC voltage from 115VAC (or 220VAC) to about 8VAC and is then rectified via bridge rectifier BR1 to about 11.52Vdc. C1 filters off the AC ripple. If you find the circuit output too noisy add another electrolytic capacitor over the output terminals. Value can be between 10 and 100uF/25V. The output voltage is variable with the 10K-potentiometer while keeping the current constant.

T1 = 115/8 VAC transformer. Center Tap not needed.
Q1 = 2N1613, NTE128, or substitute. (TO-39 case) On coolrib!
BR1 = 40V, 4A. (Check max current of your mini-drill and add 2A)
R1 = 470 ohm, 5%
R2 = 1K, 5%
P1 = Potentiometer, 10K
C1 = 1000uF, 25V, electrolytic
C2 = 0.1uF (100nF), ceramic
