An LED (20) includes a base (24), a chip (21) and an encapsulation (22). The base has a concave depression (240). The chip is mounted at a bottom of the concave depression. The encapsulation is received in the depression for encapsulating the chip. The chip includes a light emitting surface (210). The encapsulation includes a light output surface (25) over the light emitting surface. The light output surface defines a plurality of recesses (26) for respectively receiving a plurality of deposition points (28). The deposition points have a refractive index larger than that of the encapsulation.
