The invention discloses an illuminating light fixture efficient in heat dissipation. The illuminating light fixture comprises a shell, a heat dissipator, an LED light-emitting assembly, a lamp shade and an emergent light improvement assembly. An opening hole and a light outlet are formed in the two ends of the shell correspondingly. The heat dissipator is arranged on the opening hole in an embedded manner. A mounting portion and a heat dissipation portion are arranged at the two ends of the heat dissipator correspondingly. The heat dissipation portion is arranged outside the opening hole in an exposed manner. The mounting portion is contained in the shell. The LED light-emitting assembly comprises multiple LED lamp beads. All the LED beads are arranged on the mounting portion. The emergent light improvement assembly comprises a first improvement piece and a second improvement piece. The first improvement piece is attached to the inner side wall of the shell. By means of the illuminating light fixture efficient in heat dissipation, the design effects that the illuminating light fixture efficient in heat dissipation is small in size and low in weight can be achieved; and good heat dissipation performance is achieved. The effects that light rays are reflected and / or refracted and / or scattered are small; the fine adjustment effect can be achieved, and in other words, the light rays can be processed in a finer manner; the emergent light ray requirement is met better; and the illuminating light fixture is high in light ray utilization rate and good in illumination effect.

The invention relates to the technical field of semiconductors and discloses an image sensor. A laminated layer formed by a first medium layer, a second medium layer and a third medium layer is taken as a side wall reflection layer around a medium layer above the surface of a photosensitive area, so that a light path is constructed; light is limited in a corresponding pixel photosensitive area to be prevented from being emitted into an adjacent pixel photosensitive area; and therefore, the cross-interference can be reduced, and the effective photosensitive efficiency of the photosensitive area can be improved. The image sensor has the beneficial effects that the incident light is limited on the basis of a refractive index difference between the first medium layer and the interlamination medium layer, and the second medium layer, namely the metal layer, only reflects the light transmitting through the first medium layer, so that the absorption effect of metal on the light is relieved to a certain extent; and furthermore, the laminated structure ensures a polishing effect during a subsequent chemical-mechanical polishing process, and the metal can be prevented from falling off and stripping.
