摘要： Disclosed are a chip-type LED package and a light emitting apparatus having the same. The chip-type LED package includes a thermally conductive substrate with lead electrodes formed thereon. An LED chip is mounted on the thermally conductive substrate, and a lower molding portion covers the LED chip. In addition, an upper molding portion having hardness higher than that of the lower molding portion covers the lower molding portion. The upper molding portion is formed by performing transfer molding using resin powder. Accordingly, since the lower molding portion can be formed of a resin having hardness smaller than that of the upper molding portion, it is possible to provide a chip-type LED package in which device failure due to thermal deformation of the molding portion can be prevented.
