Abstract
A light source device in the present invention includes a substrate, a light-emitting chip, a transparent sealant, and a top cover. The substrate has a supporting surface. The light-emitting chip is disposed on the supporting surface. The transparent sealant covers the light-emitting chip and is located on the supporting surface. The transparent sealant has a light-emitting surface located outside a side surface of the light-emitting chip. The top cover covers a side of the transparent sealant opposite to the substrate, and clamps the transparent sealant together with the substrate, and the light-emitting surface is located between the substrate and the top cover. A reflectance of the top cover is greater than a transmittance of the top cover, and the transmittance of the top cover is greater than 0.1%.
