Abstract

A light-emitting diode (LED) lamp forming a light distribution mode of an approximate parallel optical array by using lenses is provided. The LED lamp includes substrates (1) for mounting LEDs (10), reflectors (2), a power source (5), and a top cover (6). Each of the substrates has a condenser lens (11) at a front end of each of the LEDs (10), and the condenser lenses (11) are used for converging beam angles of the LEDs (10). The plurality of LEDs (10) is arranged in a matrix to form an approximate parallel optical array. The reflectors (2) each have a curved surface (21) for performing reflection and light controlling on light rays reflected and controlled by a curved wall. The LED lamp realizes uniform lighting in the whole lighting range through performing lens condensing once and reflection light controlling once, thereby achieving excellent directivity of illumination and uniform brightness, and eliminating the glare phenomenon.
