LED lamp for dairy barns - design and thermal management

Full color white light, temperature self‐monitor, and thermochromatic effect of Cu+ and Tm3+ codoped germanate glasses

“…It is well known that the temperature of the high‐power LEDs during working period is usually high owing to the heat deposition in the LED chips, thus the thermal management is an important issue which should be taken into account while designing LED‐based lighting devices 24‐26 . That is to say that the temperature self‐monitor and the timely feedback to the power supply system are necessary for advanced lighting engineering.…”

“…It is well known that the temperature of the high-power LEDs during working period is usually high owing to the heat deposition in the LED chips, thus the thermal management is an important issue which should be taken into account while designing LED-based lighting devices. [24][25][26] That is to say that the temperature self-monitor and the timely feedback to the power supply system are necessary for advanced lighting engineering. Moreover the temperature detection is important not only during the lighting hours but also during the non-working period of the lighting device since the temperature report can reflect the working status of the devices and can also alert us for the unusual temperature of the environment.…”
