1. Scenario lighting: Design lamps and lanterns according to the needs of the environment. Scenario lighting takes place as the starting point, and aims to create a beautiful and gorgeous lighting environment to enhance the scene effect and make people feel the atmosphere of the scene.

2. Mood lighting: lamps are designed according to the needs of people. Mood lighting is based on human emotions and creates a mood-like lighting environment from the perspective of people. Mood lighting includes four aspects: one is environmental protection and energy saving, the second is health, the third is intelligence, and the fourth is humanization.

"Emotional Lighting Book" is the first book in China to lead the trend of LED lighting design, breaking the long-term monopoly of design theory by foreign giants, making the application of LED easier for the market. Contribute the latest mood lighting design concepts to share with you, and hope that more experts, scholars and designers will participate in the discussion and put forward suggestions

The principle of LED lights:

Light-emitting diodes are mainly composed of PN junction chips, electrodes and optical systems. The area of its illuminator-chip is 10.12ml (1mil=0.0254 square millimeters). Currently, there are large-chip LEDs in the world, with a chip area of 40mil.

The luminescence process consists of three parts: carrier injection under forward bias, recombination radiation and light energy transfer. A tiny semiconductor wafer is encapsulated in a clean epoxy. When electrons pass through the wafer, the negatively charged electrons move to and recombine with the positively charged hole region. The electrons and holes disappear and photons are generated. The larger the energy (band gap) between the electron and the hole, the higher the energy of the resulting photon. The energy of the photon, in turn, is Corresponding to the color of light, in the spectrum range of visible light, blue light and purple light carry the most energy, and orange light and red light carry the least energy. Since different materials have different band gaps, they can emit different colors of light.
