The luminous performances of remote phosphor with domed, elliptical and conical shapes under various drive currents and light intensity distributions are researched. A blue LED is used as the light source to excite YAG:Ce3+ phosphor to emit white light. Meanwhile, constant-current sources and TEC heat sink controllers are used to control LED driving current and heat sink temperature respectively. Comparing the optical and chromatic parameters of three remote packing phosphor samples with different shapes, it is found that the elliptical sample has the best optical characteristics and the highest luminous flux. Yellow-blue ratio (YBR) spatial distribution tests of the three kinds of remote phosphor are performed respectively under different currents. The domed sample shows the best YBR spatial distribution uniformity, ACCTD and ACU value are the best among three samples. Comparing to big angle, the YBR values of the three samples measured closed to 0° decrease at different levels for the phosphor layer at the normal direction of the chip far away from the light source and shorter optical path in phosphor, so the excitation effect is different from that of the big angle exit light. Based on experimental phenomenon, shapes of light source encapsulation and phosphor layer become important factors to influence light distribution. Therefore, the exit light path is optimized through changing the packing way of the remote phosphor, which is important to improve remote phosphor illumination performances and has better reference to the research on high power white light LED optical performances.
