Wavelength conversion device and preparation method thereof
The invention belongs to the technical field of illumination, and discloses a wavelength conversion device and a preparation method thereof. The preparation method of the wavelength conversion device comprises the following steps: preparing fluorescent ceramic: processing and forming a fluorescent ceramic material into a first hollow cylinder, cutting the first hollow cylinder into more than two sector ring cylinders with inner side surfaces, outer side surfaces and tangent planes, and polishing; the inner side face, the outer side face and the tangent plane of each sector ring cylinder are coated with reflection slurry, baking is conducted, and the sector ring cylinders with the pre-bonding layers are obtained; splicing sector ring cylinders: splicing the sector ring cylinders with the pre-bonding layers together, and presintering to form a second hollow cylinder; preparing a fluorescent chip: cutting the second hollow cylinder to form a plurality of annular sheets, and sintering to obtain the fluorescent chip; and packaging the fluorescent chip: packaging the fluorescent chip to obtain the wavelength conversion device. The reflecting layer improves the luminous efficiency and the tolerance limit blue light power of the wavelength conversion device.
本方案属于照明技术领域，公开了一种波长转换装置及其制备方法。该波长转换装置制备方法包括制备荧光陶瓷：将荧光陶瓷材料加工成型为第一中空圆柱体，将第一中空圆柱体切割形成两个以上具有内侧面、外侧面和切面的扇环柱体，抛光处理；制备预粘结层：在每个扇环柱体的内侧面、外侧面和切面上涂覆反射浆料，烘烤，得到有预粘结层的扇环柱体；拼合扇环柱体：将具有预粘结层的扇环柱体拼合在一起，预烧结，形成第二中空圆柱体；制备荧光芯片：第二中空圆柱体切割形成多个环形片，再烧结得到荧光芯片；封装荧光芯片：对荧光芯片进行封装处理，制得波长转换装置。反射层实现对波长转换装置发光效率和耐受极限蓝光功率的提升。
