Preparation method of high-thermal-conductivity diamond film fluorescent glass and semiconductor lighting product thereof
The invention discloses a preparation method of high-thermal-conductivity diamond film fluorescent glass and a semiconductor lighting product thereof. The preparation method comprises the steps: uniformly mixing glass powder, fluorescent powder and an organic solvent to prepare fluorescent glass slurry; uniformly coating a transparent substrate with the prepared fluorescent glass slurry, and preparing fluorescent glass on the transparent substrate in a sintering manner; depositing a layer of diamond film on the fluorescent glass through a chemical vapor deposition technology, so as to obtain the diamond film fluorescent glass; and finally, taking the diamond film fluorescent glass as a fluorescence wavelength conversion material, and pasting the diamond film fluorescent glass above a semiconductor chip module to obtain the semiconductor lighting product. Heat generated by the fluorescent glass is quickly dissipated through the high-heat-conductivity diamond film, so that bad effects such as thermal quenching caused by heating of the fluorescent glass can be prevented, the service stability of the fluorescent glass can be improved, and the light color stability of the semiconductor lighting product is ensured.
本发明专利公开了一种高导热金刚石薄膜荧光玻璃及其半导体照明产品的制备方法。制备方法包括：首先将玻璃粉、荧光粉和有机溶剂混合均匀制成荧光玻璃浆料；接着将制备的荧光玻璃浆料均匀涂覆在透明基底上，并通过烧结方式在透明基底上制备出荧光玻璃；再通过化学气相沉积技术在荧光玻璃上沉积一层金刚石薄膜，从而获得金刚石薄膜荧光玻璃；最后将金刚石薄膜荧光玻璃作为荧光波长转换材料，贴放在半导体芯片模组上方，获得半导体照明产品。本发明专利通过高导热的金刚石薄膜将荧光玻璃产生的热量迅速耗散掉，不仅可防止荧光玻璃发热产生热淬灭等不良效果，还可以提高荧光玻璃服役稳定性，从而保证半导体照明产品的光色稳定性。
