Amazing:super-simple zero- power LED Light DIY
REVIEW: how to do if the power failure? Still use candles? If so, you are out ! Today I will teach you how to use the telephone line to produce the LED light, which is super simple and not afraid of blackouts and cost the electricity, the tech is not high , everyone can DIY and can not help trying!-
DIY is to spend less exhausted making a night light. Almost no technical content ,which is drawing the happy … well , come to the question :
DIY materials needed :
The white LED light board that i
DIY Cost:
Removing artificial , less than one yuan .
DIY time:
No more than one hour.
DIY Steps:
First, remove the current limiting resistor on the original LED light panel to change with the resistor that is more power and resistance .
I use 0.5w 5.1k resistor, the resistance can be actually around the 5.6k , the low resistance is brighter , the higher resistance is darker , but not less than 4.7k, otherwise which may be burn the LED light at a time of high voltage. Only change a resistor is OK .
Followed by drilling holes in the mineral water bottle , through the network cable .
Then connect a network cable with a crystal head of the telephone line . Crystal head has four lines, in fact, only connecting the two is enough.
Again series three LED light panels and connect the network cable
Finally, cut half bottle of mineral water , screw the cap , call it a day .
Because the circuit is too simple , not described with the map . estimated friends of the altar with the toes can think how the wiring is connected… no map no truth , see results below .
Followed by the upgrade. Because the water bottles too light , it is not convince to place , so instead of glass jam jars . At the same time the waste small switch removed from a toy is installed on the cap. Upgraded version is also completed.
This is night light making advantage of the telephone line to be powered. Because the phone lines are been smooth , so do not worry about power outages. According to my tests , there is no problem that while driving three such nightlight at least. The reason why the resistance should not be too small is that the voltage will be increased when the phone is ringing ,if the resistance is too small , then the current will be large . after the phone is taken,if the nightlights current is too small, it is not bright , but as soon as the phone put away , and restore to . Moreover, this call makes no effect on nightlights …
Last nagging one : The phone line is DC , if plug the night light,which does not shine , exchange the wiring polarity.
The DIY that is easy to learn provide us with the emergency lighting and decorative handicrafts at home , of course, the core part of the production process is the LED lighting , thanks to the LED lighting whose lighting principle is the semiconductor light-emitting diodes,which can be more flexible combine with the electron , this process is the embody of the perfect combination of LED lighting and electronic communications ,how amazing!
Nowadays,the LED flood lamp and LED tube light are the most widely used as the representatives of the decorative lighting and the home lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood lamp is mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile,there a large number of factory engaging in developing and producing the LED light,Lead Lighting is just one of them,which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED floodlight so that fully guaranteed stable and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood light, while low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood lamp and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection,login http://www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com to know more awesome LED floodlights and other LED lighting.
