SEALANT FOR SEMICONDUCTOR LIGHT EMITTING DEVICE AND METHOD FOR MANUFACTURING SUCH SEALANT, AND SEMICONDUCTOR LIGHT EMITTING DEVICE USING SUCH SEALANT |
摘要 |
To provide novel semiconductor light-emitting device member superior in transparency, light resistance, and heat resistance and capable of sealing semiconductor light-emitting device and holding phosphor without generating cracks or peelings even after use for a long time, the member meets the following requirements: (1) comprising functional group forming hydrogen bond with hydroxyl group or oxygen in a metalloxane bond, on the surface of ceramic or metal, (2) maintenance rate of transmittance at 400nm wavelength before and after left at 200°C for 500 hours is between 80% to 110%, (3) no change is observed by visual inspection after irradiated with light having 380nm to 500nm wavelength, whose center wavelength is between 400nm and 450nm both inclusive, for 24 hours with 4500W/m 2 illumination intensity at 436nm wavelength, and (4) refractive index at 550 nm wavelength is 1.45 or larger. |
