Maya Tutorials: Two lighting case studies

I do not know if anyone has translated this tutorial, I look good on the translation to everyone.

The following two examples are highly dependent on real-world observations. For myself, I've used digital photos, sketches, and noticed the lighting on these. These incomplete examples and information will be updated. Please let me know if you have any suggestions for me to improve my work.

Lamp

In this simple example, I use two spotlights. The first lamp was placed under the shape of the light bulb and illuminated downward. Another analog lamp illuminates the lampshade, so it is placed underneath the first and so on and in a direction. I choose the spotlight because its cone angle is ideal for simulating the light propagation of real lights. I have considered using a point light source to make the light come from the bulb more persuasive, and the point light must be placed inside the bulb (like a filament in a real bulb). In this case the light source will be completely wrapped inside the geometry and therefore cannot be seen.
