Advantages of Ceramic Materials in LED Engineering Lighting Products
May 17,2018
The combination of LED lights and ceramic materials has resulted in a new integrated lighting fixture, maximizing the advantages of ceramics. Ceramics do not retain heat and are not fully enclosed; they have a microporous structure that increases the contact area with air, allowing for direct heat dissipation without affecting the heat dissipation performance of the LED lights.
Compared to lamp bodies made of aluminum substrates with overlaid metal materials, the active radiation heat dissipation capability of ceramic integrated lighting fixtures is 8.8 times stronger under natural convection conditions, making the heat dissipation advantages very obvious.
Ceramic materials are non-conductive and serve as excellent insulators, effectively enhancing the safety of LED engineering lighting products, which is not the case with other metal materials. Considering all factors, ceramics are the most suitable insulating material for use in LED engineering lighting products.
Ceramics are inherently insulating, high-temperature resistant, oxidation resistant, acid and alkali resistant, resistant to thermal shock, and have a low thermal expansion coefficient, ensuring the stability of LED engineering lighting products in high and low temperature environments or other harsh conditions.
Ceramics can withstand high pressure, prevent electric leakage breakdown, operate silently, and do not create coupling parasitic capacitance with LED engineering lighting products, thus simplifying the filtering process; the required creepage distance is shorter than that required for metal bodies, further saving space in LED engineering lighting products, which is beneficial for engineers' designs and electrical certification.
