Abstract
A dual-channel heat-conducting encapsulation structure of a solid-state phosphor integrated light source has a solid-state phosphor, a transparent organic silica gel, LED chips and a substrate. The LED chips are arranged on the substrate. The dual-channel heat-conducting encapsulation structure also has heat-conducting columns fixed on the substrate, and the heat-conducting columns are disposed away from the LED chips; the solid-state phosphor is placed on the heat-conducting columns without contacting the LED chips; the transparent organic silica gel is filled in the gap between the solid-state phosphor and the substrate. By adopting the design of double heat-conducting channels, separates two heat sources of the LED light source to sufficiently conduct the heat, the heat of the solid-state phosphor and the LED chips reaches the substrate through the respective channels, and then is transferred from the substrate through the heat sink into the atmosphere.
