    摘要: A method of forming an LED lamp with a desired distribution of phosphor is disclosed. The method includes the steps of mixing a plurality of phosphor particles in an uncured polymer resin for which the viscosity can be controlled in response to temperature to form a substantially uniform suspension of the phosphor particles in the resin. The uncured resin is then placed into a defined position adjacent an LED chip and the temperature of the resin is increased to correspondingly decrease its viscosity but to less than the temperature at which the resin would cure unreasonably quickly. The phosphor particles are encouraged to settle in the lowered-viscosity resin to a desired position with respect to the LED chip, and the temperature of the resin is thereafter increased to the point at which it will cured and solidify.

    摘要: A light emitting diode lamp is disclosed that includes a resin package that defines a recess in the shape of a solid polygon or another three-dimensional solid. The recess includes a floor, two side walls along the respective longer sides of the floor, and two end walls along the respective shorter sides of the floor. The two side walls define an angle therebetween greater than 3°, and the two end walls define an angle therebetween greater than 40°. A light emitting diode chip is positioned on the rectangular floor of the package.
