Led Ceiling Lighting (307)

The classic yellow light bulb has led me to make led lighting because it is no longer tightened in the interior lighting and excessive eye on the dark road. The LEDs illuminate a certain angle in the direction it is facing. There are varieties between 20-150 degrees. In this application, I used mushroom led to keep the angle large. . Material list: -20 pieces of mushroom led-100 ohm resistance-Perforated pertinaks-Soldering Iron-Solder Wire-Copper wire First we cut the perforated pertinac to fit the sensory, then we arrange the leds in the pertinac accordingly. We knit with copper wire from the holes to act as a bottomless bulb so that it fits from the bottom of the pertinac. These wires form our supply tension. Circuit type (Parallel arms can be increased, but the brightness of the LEDs will decrease.) The LEDs are soldered and fitted to the socket. Now we can put the senses in place. However, it may not work in the first place. The reason is that we reverse the feeding. The solution to this is to change the paths from the wires we knit to the LEDs. So we gave the (+) legs to the (+) legs (-), (+) legs In order to correct this situation, we will reverse the paths from the wires we weave to the LEDs. Front lighting Back lighting When using wide angle leds that I use in this application, it is not useful to arrange the leds very often, because the leds are wide angle, the leds between any two leds will remain passive and waste energy. In addition to this, it is reasonable to use mushroom leds in such an application, but I did not take into account. Mushroom leds glow even at very low voltages. At the moment, the leds light up with a small glow in my own car day and night. My advice is to use 5mm wide angle white leds. I would like to mention the calculation part as the number of leds will be different in other vehicles: Ceiling lights are generally provided with 5W bulbs and fed with 12 Volts. The most important point for us here is the current; Our circuit should draw a maximum of 400mA current. When we want to draw a current over 400mA, we can blow the fuse or damage the installation. If we design the led array to draw 400mA and below, it will be in our favor. In the arms, the tensions are equal. So if we look at this circuit, we have 4 parallel arms and we have 2 series connected leds on each arm. We have 12 Volt equal supply voltage on each arm. Again, 20mA current is drawn from each arm and 4x20mA = 4 arms. We need 80mA current. It is not a problem since it is below 400mA. This parallel arm We can increase it if we want. But we should not exceed 400mA. If we come to the resistance we use in the circuit; it is put in order to prolong the life of the leds and limit the current. As it can be seen in the circuit, the resistance is connected to the led group and thanks to this feature, it will reduce a certain voltage on it and thus will protect the leds. This application I do is entirely my own. However, it is my advice that other friends who will do it should follow up on someone who understands these things. Otherwise I cannot accept responsibility. I tried to explain as much as I can. There may be places I have missed / misrepresented due to the passage of time. If you report such shortcomings or mistakes, both I can see my mistakes and my other friends who want to do this application will not be wrong.

Health in their hands Ismail .. & nbsp; I have found that the best place for the Submarine led is just behind the middle mirror.

Thank you Haşim brother ..

I would do well if I could do good with walla :)

[QUOTE = EmRaH] I can do it if I can do very well with walla :) :) [/ QUOTE] & nbsp;

Health to your hands. great.

Thank you for sharing your health

It is very nice for your labor

I WAS VERY LIKE

congratulations ismail has been nice work & nbsp; :)

you will also wear submarine soon :)

I did it right on my hands, the health was very good, but the same problem occurred in me, so it keeps on, even when it's off.

[QUOTE = altay] I have done the health of your hands immediately, but the same problem occurred in me, so even if it is closed, it keeps on, even if it is a little, the leds are still lit. What is the solution of this? Can you find it? [/ QUOTE]

health to labor

Hello, I applied this application to my vehicle as I saw it from here, and it was very nice and nice, I appreciate the information that it gave at the night of the vehicle. Thank you.

I will definitely do it very well.

Your work is very good health

First of all greetings, I am a new member, I have a peugeot 206 plus, I understand from electronics.
The reason why the leds cannot be closed completely is that they can operate even at very low currents, the way to prevent this is to install 1 1-kohm resistor between the pros and cons of the leds we connect. I think it will discharge the current there immediately.

Welcome Osman Bey;

it is very nice
