The invention relates to a semiconductor light emitting device, which belongs to the field of semiconductor photoelectric devices. A semiconductor light emitting device, comprising a light collecting reflection cup and covered with the phosphor layer emitting semiconductor chip, which is characterized in that the light reflection cup and a phosphor layer in the light does not contact or contact part does not exceed the height direction of semiconductor light emitting chip, suppressing multiple reflections between the metal cup surface and fluorescent powders. To reduce the loss of light reflected in the metal cup, so that the invention of the semiconductor light-emitting device to improve light extraction efficiency. Compared with the conventional semiconductor light emitting device, it is proved that the light extraction efficiency of the present invention is increased by about 20%.
