The use of LEDs as lightingInstrumentation is one of the promising areas in lighting. The good quality of the light itself, the high brightness and directivity of the light beam, the low power consumption and the duration of work make these devices unique. It is not surprising that now there are good lamps and searchlights based on high-power LEDs, whose scope of application is constantly expanding. Automotive, LED streetlight, traffic lights and lighting of offices and buildings, billboards and video surveillance - this is not a complete list where you can use these devices.
However, in addition to the advantages, devices based onLEDs have certain disadvantages. The main one, of course, is the high cost of the device. Also, LEDs are afraid of overvoltages, which must be considered when creating projects based on such devices. However, the design of the device is simple and even for a non-expert it is quite possible to make an LED lamp with your own hands, using a set of inexpensive parts. Its power is quite enough to illuminate the room at night. It is advantageous to use LEDs as a night light, since the consumption of such a device will be several times less than that of a household device based on incandescent lamps.
In order to make the LED lampwith your own hands, we will prepare the necessary details. The housing for a night light can be taken from a standard power supply of 5-12 volts. This is the voltage and use to power the LEDs. On the outside of the plastic case, drill holes and fix the LEDs. We fasten as much as possible, it usually fits from three to five - it all depends on the power of the device. Suppose you have five LEDs connected in parallel and with a total power of 100 mA. At a voltage of 12 volt power supply, it is necessary to limit the consumption of the entire circuit with a 120 Ohm resistor. It is also desirable to solder a fuse of 100-150 mA. Follow the LED assembly sequence. Instrument anodes must
be brought together and go through restrictiveresistor to plus power supply, cathodes, respectively, through the fusible insert - to minus. Pay attention to the power supply. It must exceed the power consumption of the load. All - you made a LED lamp with your own hands. Its power is small, but this is enough to illuminate the room at night.
Now you can go ahead and make morepowerful device that will save you from overpaying electricity bills. An LED lamp with your own hands can be made for the office, it’s no secret that commercial organizations pay for electricity at inflated rates. As a case, you can use a standard fluorescent lamp, removing all parts from it and leaving one case. Fasten aluminum LED strip inside the case and feed the entire circuit from a standard power source. You have an office LED lamp, which is able to illuminate a large area.
