Abstract: The present invention relates to a heat sink apparatus, which discloses that by using a meshed member as a heat sink member, the heat-sinking efficiency will be enhanced owing to increased surface areas. Furthermore, a first linear member is made to contact with a substrate at non-perpendicular angles to increase the stresses thereof, and hence the heat sink member is more resistive to deformation during processing. In addition, the meshed member also provides multiple heat flow paths to enhance heat-sinking efficiency. The heat sink member according to the present invention can also be a 3D fabric, which further improves heat-sinking efficiency from 2D to 3D fabrics. Besides, the heat sink member includes an expanded metal-lath member.

Abstract: A luminous lamp having an ultraviolet filtering and explosion-proof thin film is disclosed. An outside of a lamp is coated by a transparent layer which comprises phosphor powder. Energy generated by the lamp is absorbed by the phosphor powder while the lamp is shining. The phosphor powder would release energy to shot brilliance, so as to provide auxiliary lighting after turning off the lamp. Additionally, the phosphor powder can absorb harmful ultraviolet and other harmful radiations with shorter wavelengths to be one part of the thin film for filtering harmful radiations. The harmful ultraviolet can be transformed by the phosphor powder into visible light to red shift radiations with short wavelengths; hence the harmful radiations with shorter wavelengths can be eliminated. The illumination of visible light can be further increased. The transparent layer can catch broken fragments of the outside of the lamp to decrease accidents when the lamp is broken.
