Efficient heat dissipation lighting fixtures

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of lamps, in particular to a high-efficiency heat dissipation lighting lamp. Background technique [0002] At present, the existing lamps generally include a radiator, a light-emitting component and a casing. The radiator is installed in the casing, and then the light-emitting component is installed on the radiator. The heat dissipation effect of the radiator is used to maintain the normal light-emitting function of the light-emitting component. In this way, since the radiator is accommodated in the casing, it is difficult for the heat on the radiator to be transferred to the external environment, which reduces the heat dissipation performance of the radiator and leads to poor heat dissipation effect of the lamp as a whole. [0003] Moreover, the existing lamps still have the problems of low light utilization rate and poor lighting effect. Contents of the invention [0004] Based on this, it is necessary ...
