In addition, by properly mixing LEDs of different colors, coupled with appropriate circuit control, the desired spectrum and color temperature can be freely mixed and modulated. LED has a large degree of freedom in optical design: LED is small in size, and it is easier to match the layout and design of various structures when designing products.LED response speed: LED response time is very fast, in the microsecond level.
LED light source is safe and reliable: LED is encapsulated by silicone, which can withstand high-strength mechanical shock and vibration, is not easy to break, and has relatively low heat generation and high safety.The average lifespan of LED components is 100,000 hours, which is far better than that of traditional light sources. This design idea describes a simple, cost-effective circuit that provides a voltage proportional to the intensity of ambient light. Moreover, the thermal deposition and light attenuation are also its weakness. Vishay has a lot of light sensors out there, and this is a nice simple lux sensor thats easy to add to any microcontroller. Ambient light sensors are used to control the brightness of the smartphone display based on ambient conditions, which has a direct impact on the user experience. LED light source has a long service life: The traditional light source such as incandescent lamps, fluorescent lamps and tungsten halogen lamps use electronic light field radiation and the filament is easy to burn.LED light source consumes less power: good LED luminous efficiency means power saving.High luminous efficiency of LED light source: LED luminous efficiency can reach 50-200 lumens / watt, and the luminous monochromaticity is good, the spectrum is narrow, and no filtering is required as a light source.
