Thermal Design of High Power Remote Phosphor White LED Package
Aiming at the heat dissipation problem of the high power remote phosphor white LED
the heat dissipation method of the package structure was studied. Based on the structure of the phosphor type white LED package and its characteristics of heat dissipation
a thermal managing method of the package was put forward
which both thermally insulated the chip and the phosphor layer and created a independent thermal dissipation path for the phosphor layer. The simulation results show that the redesigned package reduces the chip temperature by 0.55℃ and the phosphor layer temperature by 10.7℃ under the same boundary condition
indicating that the new design can reduce the phosphor layer temperature without increasing the radius dimension of the package. The effect of the thermal isolation groove on the chip base can be ignored. To achieve the optimal chip and phosphor layer temperatures distribution
the thickness of the insulation layer between the chip and the phosphor should be optimized. The new method makes the thermal management problems of the chip and the phosphor layer independent to each other
which avoids the mutual heating problems of the two
and also increases the optical design freedom of the lamp.
