Components - Light source

Light_source

It is needed to decide which light source will be best for the experimental stand. They will spotlight the 3D object from different angles like on the image below:

Blender gives some light properties, which I've set for now as follows:

• type: area
• color: {1, 1, 1},
• power: 2W,
• diffuse: 1,
• specular: 1,
• volume: 1,
• shape: square,
• size: 1 cm.

All lights are placed in Blender. It is possible to turn them on/off via the collection's Exclude from View Layer.

In commit input images, which are the results of the stand model in Blender are added to assets. Below is an example for light from 0 degrees OZ:

@kacprzak please check if is everything correct here for now. Thanks!

I have updated values for light source in blender:

type: area
color: {1, 1, 1},
power: 0.32W,
diffuse: 1,
specular: 1,
volume: 1,
shape: square,
size: 1 cm.

I am thinking about this kind of light source:

Other possible light sources are:

• W5W M-TECH Basic 12V 0,5W K W2,1X9,5D LB014W
  

• W5W M-TECH Basic 12V 0,32W K W2,1X9,5D LB069W

It occurs during "manual" test, that LB069W is enough for this stand and what's more, it is cheap.

W5W M-TECH Basic 12V 0,32W K W2,1X9,5D LB069W

And a socket for it, just standard K W2,1X9,5D socket with cables already attached:

It would be awesome to have potentiometer on the control board to have possibility to change light intensity. One potentiometer for all lights.

One thing to do after placing light on the specific height is to calculate angle of the light vector to the center of the object. It's arctan( light to center distance / height on which light is placed ).

35 cm:

40 cm:

45 cm:

The best effect of the algorithm is on the 25 cm. That position is still not so far from the object to the light and there are no "hard" shadows (completely dark places).
