Description

1356149 IX. Description of the Invention: [Technical Field] The present invention relates to a lens element, and more particularly to an asymmetrical and batwing light-shaped lens element. ^ [Prior Art] The light-emitting diode package structure is a solid-state semiconductor component with small size, long life, low power consumption, fast reaction rate and excellent shock resistance. ^ ^ 点 'Applicable to various electrical appliances, f-signal , a communication product, etc. The lens used in the traditional LED package structure: a light-emitting diode lens of 2_4, for containing a body: a beam of light emitted to a predetermined exit direction, lens two The bottom surface of := is a reflection surface opposite to the bottom surface and the penetration surface of the direction. Each part of the reflecting surface is symmetrically: the beam entering the lens is attached to the reflecting surface along the predetermined exit angle = = she passes through the lens perpendicularly to the penetrating surface: - the bottom of the lion turtle - a lens, including smooth Table: The surface of the first refractive surface of the mirror is refracted by the central axis of the mirror to be substantially perpendicular to the through-edge lens. The bottom surface of the lens enters the 1356149.1 > rate. Please refer to the seventh figure Am for the measurement of the light distribution curve of the present invention. As shown in the figure, the yoke axis 221 is aligned with the central axis of the concave portion of the first refracting body 12 in the second refracting body 22 of the light-emitting diode package 2; Intensity) is 1 au ^ ^ horse 1, first curve peak plus this) between ·5〇~5〇 angle (Angle), as shown in the seventh figure a. When the central axis 221 of the second refracting body 22 of the illuminating diode package 2 is offset from the central axis of the first rotator 12, the light intensity is __! : light curve peak _) offset angle (four) "about 25 degrees or so" as the seventh figure b. Please refer to the eighth figure, is a schematic diagram of another embodiment of the present invention. As shown in the present embodiment, A composite lens element $, straight up and having a plurality of first-refractive elements 51, the composite lens S-piece 5 can correspond to multiple light-emitting diode package structures 2 έ 此 此 此 , , , , , , ...... ...... ......
