Project Title : Natural and artificial light sources
Abstract
: An appropriate model project for the promotion of those resources to increase the
awareness of natural and artificial light sources
In my model project, which I used the materials such as wooden base, ping-pong ball, LEDs; I firstly
covered the base with a green cardboard in order to evoke the naturalness and get started to work. I
made “The sun, star, lightening and firefly” models as natural light sources. I used an orange pingpong ball as the sun and wooden parts for the others. I searched and found the star, lightening and
firefly illustrations via internet. After drawing my figures on wooden parts, asked my parents to cut
them off. And then I made the necessary paintings and wood-burning art in order to obtain my star,
lightening and firefly. In the second phase, we placed and connected complete LED system with the
help of my parents. During the installation of the LEDs we used red and yellow cables not live any
confusion with the positive and negative poles. After mounting the natural light source works on the
base, I left power connections to the next phase.
After completing artificial light sources phase by recycling materials and candles, I finished the

Project Description:
For a better understanding of natural and artificial light sources, I firstly thought about how
this application project can be handled and made simple draft drawing. After defining the
requirements, I provided the materials which are not available at home. I created a suitable
base for my project and because it is related with natural and artificial lights I pasted green
and red cardboards onto wooden bases as background. After that, we cut off wooden
“firefly, star and lightening” together with my parents and I painted the necessary parts. For
the design of firefly, I worked with wood-burning device instead of painting. At next stage I
continued with the sun model which I preferred an orange ping-pong ball to simulate it. And
I pasted wooden triangles around the orange ball in order to simulate reflections around the
sun. I took the advantage of drawings of firefly, lightening and star that I found on the
internet.
I fixed all of the artificial light works to the wooden sticks and started build up my light
system.
While building light system, I first decided where to install the LEDs and asked my parents to
drill the holes to the necessary points. Also, the orange ping-pong ball is drilled for the
preparation of LED montage in it. Then I placed all of the LEDs and made all of the
connections with the help of my parents. The cables are hidden behind the wooden sticks in
order to hide them for a good view. I created the sun, firefly, lightening and star model and
made them completely ready for the installation. After deciding the correct positions of my
natural light sources by measuring equal distances, the necessary holes for cables are drilled.
And I pulled the cables from top to bottom and fixed the items by pasting on the base.
During the installation of LED system, I used red cables for positive pole and yellow cables
for negative pole.
In the second stage, I started to work on artificial light source. Because electricity is
dangerous for children, together with my parents we made an operation on the light bulb.
The bottom side of a broken light bulb, which could be taken to recycle, is separated and the
head side is used as a cover for a tiny socket and a tiny light bulb. And taking care of the
poles, we pulled the cables to the bottom side.
My next item was an old, broken torch which we dismantled, put a bulb inside and pulled
the cables to the bottom side. Lots of materials can be used as artificial light sources but I
preferred available recycle materials and used totally 3 types together with the candle.
I fixed the artificial light sources same like the natural light sources. I measured distances,
drilled the holes, pulled the cables and pasted the light bulb and torch. Also I pasted the
candle next to them.
I completed the works on the base except the identifier plates and started to work under the
base. Because I want to operate natural and artificial light sources separately, two holes are
drill at the front side of the base for on/off switches. The on/off switches are installed to
base by keeping the button at the top and the connections at the bottom of the base. And I
started to install battery system. Because we will have two groups of lights, two battery beds
are pasted to the bottom side of the base. The red and yellow cables from LEDs helped us to
decide for poles if negative or positive, so it was very easy to decide which cable to be
connected which pole. We grouped and tidy up the cables at the bottom according to their
colors. After closing the circuit between the battery, on/off switch and lights, I tested the
system. To fix any problem easily we did not fix the cables to the base at the bottom side.
After finishing and testing the natural light source system, I passed to the artificial light
source connections. Same like the other group, because we have different colors of cables it
was easy to decide positions of cables. Same again, we closed circuit between battery,
on/off switch and the light sources, and I completed all of my works at the bottom side.
At the surface of the top side of the base, identifier plates were remaining to install. My
parents helped me to small wooden pieces to as plates. We wrote the names of the natural
light sources both in Turkish and English onto wooden plates via wood-burning art device
and pasted the plates to the correct spots. And for the artificial light sources we wrote down
the group name instead of individual names.
Finally, to give a perfect view to the whole project and to provide better appearance for the
lights, I wanted put a background wall. For the design of this wall, three wooden parts are
cut and a red single piece of cardboard pasted on them. The side edges of this carboard is
bended to give depth to the model.
After checking the whole model, I completed my project.
