Spotlight the right thing! It is useful in various fields of activity, for example: repair, shooting, etc.

Training



To build a homemade spotlight, we need:
  1. Cardboard
  2. Switch
  3. 3.7v battery
  4. Aluminum heatsink
  5. LEDs
  6. Wires
  7. Charge controller (you can just plug)
  8. Foil tape (you can take foil)
  9. Bolts (4pcs)



From the tool we need:
  1. Soldering iron (tin, rosin)
  2. Hacksaw
  3. Glue gun (rods)
  4. Stationery knife
  5. Ruler
  6. Marker (no difference)
  7. Silicone sealant
  8. Screwdriver
  9. Screwdriver (drill)


If anything, the photo does not show all the materials and tools!


LED panel assembly



Since the LEDs become very hot (if you do not use a resistor), they must be attached to the radiator.
We make a radiator 7 cm wide and 2.5 cm long.

After the radiator is ready you need to take (buy) the LEDs, I took them from two lights.

Having disassembled the lights, I pulled out two fairly powerful LEDs.

After that, you need to attach the LEDs to the radiator and put dots with a marker near them.
At these points we drill holes for the bolts (LED fastening).
Firmly tighten the LEDs with bolts.

It remains only to solder the wires with a soldering iron.


Body building



On a cardboard panel, draw approximately as shown in the picture. If all values ​​are expressed in centimeters!

All this is carefully cut with a clerical knife, and it should turn out something like this:

All this must be carefully glued together with a glue gun.

From the inside of our future searchlight, it is necessary to paste over with foil tape or foil. The foil will act as a kind of reflector!


Putting it all together


We insert the finished LED panel into the hole in the housing, bringing the wires from the LEDs out. After the edges of the panel glue with sealant. DO NOT Glue THE ADHESIVE GUN, FROM HEATING THE RADIATOR THE ADHESIVE MELT FUSE !!!

Now you need to attach the battery, switch and charge controller to the back of the spotlight.

The last part remains - to solder everything together! How to solder can be seen in the photo below.



If you did everything correctly, then the spotlight should shine.
From my own experience of use, such a spotlight perfectly illuminates the entire room!

How do you

You would, for starters, figured out your many shoals before telling me what to do. Since you apparently are not going to answer questions, I re-advise you to correct your profile.

Ivan_Pokhmelev, before evaluating and finding flaws in other people's articles, try to write an article yourself, and then talk about someone else's shoals. Good luck

Of course, a millimeter - usually in the drawings it is this unit. And you measure with a centimeter - .. The comment is not for you, but for the author of this opus.

You probably meant by “correct unit” “mm” and not “SM”? The unit "SM" does not exist, and Siemens (See) has nothing to do with it.

So if you fumble, just the right unit (SM) would like to remind you who measures in See ... dance

Let's continue the questions to the electronic "ball":
1. What is the area of ​​the radiator?
2. What current are the LEDs supplied with?
3. Why was not heat-conducting paste used?
4. Why was soldered with tin, and not solder?
5. Why such an ugly soldering?

Bolts (4pcs)
Judging by the photo - not bolts, but screws.
radiator 7 cm wide and 2.5 cm long.
And not vice versa? In extreme cases - 7 cm wide and tall 2.5 cm. By the way, so far no one has canceled the separation of the fractional part comma!
Having disassembled the lights, I pulled out two fairly powerful LEDs.
To make this freak, in which they quickly die?
All this is carefully cut with a clerical knife
Why carefully, if the sizes of the sides do not fit together? )))
The location of the switch gives the product an indescribable charm. )))

Derikso as not to disgrace, remove this boast from your profile:
Sharyu in electronics
