Different types of lighting dimming protocols explained.

1. 0-10V: This is an analog dimming protocol that uses a 0-10V control signal to adjust the brightness of lighting fixtures.
2. DALI (Digital Addressable Lighting Interface): This is a digital protocol that uses a two-wire system to control lighting fixtures and allows for individual addressability and control of each fixture.
3. DMX (Digital Multiplex): This is a digital protocol that is commonly used in stage lighting and architectural lighting to control multiple lighting fixtures at once.
4. PWM (Pulse Width Modulation): This is a digital dimming protocol that works by rapidly turning the light on and off at a high frequency, effectively controlling the brightness by adjusting the duty cycle of the pulse.
5. Triac: This is an analog dimming protocol that works by controlling the amount of current that reaches the lighting fixture, effectively controlling the brightness.
6. RF (Radio Frequency): This is a wireless protocol that uses radio signals to control lighting fixtures.
7. Zigbee: This is a low-power, wireless protocol that is often used in smart home lighting systems.
