1. The weekly report summarizes the work of Mr. Nattapat Boonpat, student ID 54261510, who is a member of the Instinct group. 2. This week, Mr. Boonpat researched LED lights, finding that normal LED lights are simpler, cheaper, and easier to use than RGB LED lights, which use more energy. 3. He looked for RGB LED lights with good light distribution but found that most have no distribution because RGB lights requiring high power are rare.

Weekly Progress
I was assigned to work in the LED. From which I was assigned to find out about the LED found that.
The LED used in the present, there are many. And LED RGB uses more energy than normal. So, I
think. The normal LED is simple to use. And cheaper. Easy to use with device. This week I have been
looking for an LED RGB light distribution. Found that, most have no light distribution because the
power LED RGB light very rare. The LED is the power supply 3V that 7 is a light color is red bule
green white orange pink and blue. The LED colors are mixed. To get the desired color.
