    Abstract: A wavelength-converting device includes a substrate and a reflective layer. The reflective layer is disposed on the substrate, among which when an operating temperature of the reflective layer is higher than or equal to 130° C., the reflective layer is formed of a first metallic material, and when the operating temperature of the reflective layer is lower than 130° C., the reflective layer is formed of a second metallic material. The reflectivity of the second metallic material is higher than the reflectivity of the first metallic material at room temperature. By forming the reflective layer of the first metallic material and the second metallic material at different operating temperatures, respectively, the decay of the reflectivity is effectively avoided, the reflectivity is optimized, and the converting efficiency of the wavelength-converting device is enhanced.

    Abstract: A wavelength-converting device includes a first substrate, a second substrate and a first wavelength-converting material. The first substrate has a first region and a first engagement portion. The second substrate is disposed adjacent to the first substrate and having a second region and a second engagement portion. The second engagement portion and the first engagement portion have complementary shapes. The first wavelength-converting material is disposed on the second region for converting a light in a first waveband into a light in a second waveband. The light in the first waveband is transmitted through the first region, and the light in the second waveband is reflected by the second region. The first region and the second region are staggered, so that the first engagement portion and the second engagement portion are engaged and fixed with each other. As a result, the safety and stability are enhanced, and the noise is reduced.

    Abstract: A wavelength-converting device used for converting first waveband light includes a transmissive substrate, a phosphor layer and an optical layer. The transmissive substrate has a refraction coefficient ns, the refraction coefficient ns is greater than an environmental refraction coefficient namb. The phosphor layer is disposed over a side of the transmissive substrate for converting the first waveband light into second waveband light. The optical layer is disposed over the other side of the transmissive substrate opposite to the phosphor layer for reflecting the second waveband light. The optical layer has an effective refraction coefficient nr. The relation between ns, namb and nr is given by nr>2(namb2)/ns. As a result, the light leakage is avoided, the fabrication is simplified, and the difficulty of material selection is reduced.
