LENS AND LED LAMP USING APPLICATION THEREOF

摘要

A lens (1) and LED lamp (3) using an application thereof. The lens (1) comprises: a lens main body is a structure formed by a convex curved light exit surface (11), an installation surface (10) opposite to the light exit surface (11), and two opposing end faces (12) adjoining the light exit surface (11) and the installation surface (10); the installation surface (10) of the lens main body is concave inwardly to form a light entrance surface; the light entrance surface comprises a pair of side surfaces (151) disposed towards the two opposing end faces (12) of the lens main body and a connecting surface (152) connecting the pair of side surfaces (151); the two end faces (12) of the lens main body are concave inwardly to form light reflecting surfaces (1211) towards an LED light source (2). The LED lamp (3) provided with the lens (1) is advantageous in that a light distribution effect of one of a lateral angle and a longitudinal angle can be almost seven times different from that of the other and in a high optical efficiency. Further, the optical components in the LED lamp (3) can have various combinations to meet various types of requirements for marine signal lamps.
