Abstract: A LED lamp includes an LED module and thermo-conductive members. The LED module has a transparent base, a plurality of LEDs mounted on the transparent base and a transparent film covering the LEDs. The transparent base has thermo-conductive sections and electro-conductive sections. The thermo-conductive members are attached on the thermo-conductive sections. Thereby, the invention can omnidirectionally emit light and has great effect of heat dissipation.

Abstract: An optical lens includes a main body having an outer convex surface and a bottom surface opposite to the outer convex surface. The bottom surface has an inner concave surface which is concave toward the outer convex surface. The outer convex surface and the inner concave surface cooperatively form two positive lens portions and a negative lens portion. The positive lens portions and the negative lens portion are arranged in a triangular configuration.

Abstract: A street lamp includes a lamp post, a lamp holder connected to the lamp post, and a lighting module mounted on the lamp holder. The lighting module includes a printed circuit board, a plurality of light emitting diodes arranged on the printed circuit board and a plurality of optical lenses. Each of the optical lenses has a main body having an outer convex surface and a bottom surface opposite to the outer convex surface. The bottom surface has an inner concave surface concave toward the outer convex surface. The inner concave surface defines a cavity for containing at least a part of one of the light emitting diodes. The outer convex surface and the inner concave surface cooperatively form two positive lens portions and a negative lens portion. The positive lens portions and the negative lens portion are arranged in a triangular configuration.
