FIELD: lighting.
SUBSTANCE: invention relates to lighting devices, specifically to optical lighting devices based on light-emitting diodes. Present invention consists in that system holder is made from heat-conducting material, for example metal, holder base comprises a sealing gasket; system provides availability of air gap between lens with an irregular shape and light-emitting diode; lens with an irregular shape is additionally glued to holder by a sealing composition; collecting lens is located on inner faces of lens with an irregular shape, deflecting faces of lens with an irregular shape are designed so that LED light flux passing through them is diverted to external face of lens with an irregular shape, so that outer faces reflect light flux using effect of total internal reflection.
EFFECT: creation of a lens for light-emitting diode capable of maintaining its operational characteristics and characteristics of light-emitting diode from environment, which is achieved by design of optical system consists of aspheric lens irregular shape and holder of heat-conducting material.
