Disclosed is a new lens device for an LED capable of improving the workability of mounting a lens on multiple LEDs installed on a circuit board successively by mounting the lens in a panel shape with 2-row X 17 lens parts on the circuit board and capable of improving diffusion efficiency of light by reflecting light generated from the LED to all directions multiple times in a stage before the lens reaches the surface of the lens and diffusing and reflecting the light at the surface of the lens. By the lens device for an LED comprises 2-row X 17 lens parts on a single panel with a size capable of covering multiple LEDs successively installed on the circuit board along the horizontal and vertical directions; multiple screw insertion bosses on a central line of the panel in the longitudinal direction at constant intervals for inserting screws fixing and mounting the panel on the circuit board; an LED insertion groove, in which the LEDs installed on the circuit board are inserted, on a rear central part of the each lens part formed on the panel; multiple inclined planes with different slopes on the inner circumferential surface of the LED insertion groove; a horizontal first reflective surface at the central part of the surface of the lens part; and a rounded second reflective surface at the edge of the surface of the lens part. |
