lit up electrical light with lighter

We lit up electric light like we lit up candle. This application is great for some special case. for example, to celebrate the birthday.

Edison invent electric light, it change the way of lighting.
This project do something conversely.
We will lit up electrical light with lighter which usally used to lit up candle.
In other word, we lit up electric light like we lit up candle.

Let's Begin!

How does it work?

I've one Temperature to 0-5VDC converter, which convert the temperature sensing from PT100, and convert it to voltage, which supply the power to LED accordingly.

The number array is made of standard 3mm LED,the more leds you use, the more connections and labor time will be required.

+/- polars is parallelly connected.

here 3mm stainless probe pt100 sensor is selected, it response very fast. the led is lit up as the lighter  start to heat the sensor probe. see sensor wiring picture.

  Are you sure? yes | no

Maybe use infrared light sensor. Photo-transistor. Because temperature sensor is a bit heavy, and it needs time to warm up.
