LIGHT-EMITTING DIODE LAMP WITH OPTICAL ELEMENT Russian patent published in 2017 - IPC F21S8/00 

FIELD: lighting.

SUBSTANCE: invention relates to lighting engineering and can be used as light-emitting diode light source for outdoor, industrial, household and architectural and design lighting. Light-emitting diode lamp (LEDL) with optical element has base, transparent optical element, which generates light flux, light-emitting diode module and power supply source. Used base is reflector, on which transparent optical element is fixed, on upper surface containing mutually parallel straight line notches. Light-emitting diode module (LEDM) is attached to one of transparent optical element end sides. LEDL is equipped with additional LEDM, attached to one of transparent optical element lateral sides so, that its light flux is directed in parallel to lines of transparent optical element notches, wherein transparent optical element notches are made so, that angle between lines of notches and light fluxes directions is 90°. LEDL can be equipped with additional LEDM, attached to each of transparent optical element lateral sides so, that their light fluxes are directed in parallel to lines of transparent optical element notches. LEDL can be equipped with dissipating cover rigidly attached to base – reflector, in cross-section having U-shaped profile. LEDM can be made in form of printed circuit board with n ≥ 1 LEDs, wherein transparent optical element height exceeds light-emitting diodes on LEDM width by value of ± 10 %. Free from LEDM transparent optical element end sides can be coated with light-reflecting paint layer, wherein transparent optical element width a is in range of 100 mm ≤ a ≤ 550 mm, and ratio of distance s between notches to transparent optical element width a is s/a = (0.01 x 0.1) mm. LEDL can contain one or more additional transparent optical elements with mutually parallel notches and LEDM, attached to optical element end or to end and lateral sides, wherein transparent optical element notches are made so, that angle between lines of notches and light flux directions of, at least, one LEDM is 90°.

EFFECT: technical result is providing uniform illumination, reduction of labor input and weight and dimensions, increasing degree of dust and moisture protection.
