Abstract

The invention discloses a solid package LED cold light source. The solid package LED cold light source comprises a package bottom shell, an integrated optical source chip, a driving circuit board andan electric power conductor. The package bottom shell comprises bottom shell side walls and a bottom shell bottom wall. The bottom shell bottom wall is located at the lower ends of the bottom shell side walls. The integrated optical source chip covers the upper ends of the bottom shell side walls. The bottom shell bottom wall is provided with a conductor lead-out hole allowing the electric power conductor to penetrate through. The driving circuit board is arranged in the package bottom shell. The package bottom shell is filled with a waterproof heat conducting pouring sealant. The solid package LED cold light source provided by the invention has high water resistance and can be applicable to various outdoor occasions with high water resistant requirement.

Description

technical field [0001] The invention relates to the technical field of LED light source products, in particular to a solid-state packaged LED cold light source. Background technique [0002] LED light sources have many advantages such as energy saving, environmental protection, gorgeous colors and long service life, and have become mainstream products in the field of image display and lighting. The waterproofness of the LED light source used in outdoor occasions is an important performance index to ensure normal operation and service life; the existing problems of the waterproof LED light source in the prior art mainly include: [0003] On the one hand, the waterproof performance is limited, and usually it can only block the water flow in a certain direction, but cannot prevent water from entering the LED light source in all directions; Baking, low-temperature freezing, ultraviolet radiation, oxidizing gas oxidation, and corrosion of corrosive substances will significantly ...
