The pedestal 11 of the light-emitting diode 1 is received in the second receiving groove 215 of the lens 20. The top surface 111 of the base 11 abuts against the second positioning surface 216 of the support portion 21, and the four portions of the support portion 21 The two sharp corners 22〇 abut against the four corners 112 of the base 11. The light-emitting surface 134 of the light-emitting diode 10 is spaced apart from the light-incident surface 25 of the lens 20 to form an air gap. The light emitted from the light-emitting diode 10 from the light-emitting surface 134 is 098134065. The form number is Α0101. Page 8/23 pages 0982058316-0 201113473 The light-incident surface 25 of the lens 20 is incident on the inside of the lens 2, and passes through the light-emitting surface of the lens 20. 230 shots. Since the light exiting surface 230 of the lens 20 is deflected to the left with respect to the pupil plane, the central axis II of the light exiting surface 230 of the lens 20 is leftward with respect to the central axis I of the light emitting diode 10, and the light emitting surface 134 of the self-emitting diode 10 is emitted. Most of the light is deflected to the left by the light exit surface 230 of the lens 20. Therefore, the lens 20 of the present invention can concentrate most of the light of the light-emitting diode 1 左侧 on the left side of the pupil plane, that is, the light distributed on the left side of the pupil plane in the light emitted by the light-emitting diode module 1 More light than the right side of the pupil plane. [0014] FIG. 5 shows an equal illuminance distribution diagram of the illuminating diode core group 1, in which a receiving screen is disposed 10 meters directly below the illuminating diode module 1, and the receiving screen is parallel to the ΧΟΥ plane . The light shape 40 of the LED module 1 on the receiving screen has a longitudinal shape, and the length of the light shape 40 in the front and rear directions is greater than the width in the left and right direction of the light shape 40, and the right side 41 of the light shape 40 is concave, and the light shape 40 is concave. The left side 42 is convex, that is, under the polarizing action of the lens 20, when the light emitted by the light-emitting diode 10 is emitted through the light-emitting surface 230 of the lens 20, most of the light is concentrated on the left side of the pupil plane. 6 is a right angle coordinate light distribution diagram of the light emitting diode module 1. The solid line 44 of FIG. 6 shows the light shape distribution of the light emitting diode module 1 at the pupil plane, and the solid line 43 of FIG. 6 shows the light emitting diode. The body module 1 has a light-shaped distribution on the pupil plane. Referring to the solid line 44 of FIG. 6 and FIG. 3, the angle of the ΖΟΥ plane on the left side of the Ζ axis is defined as a negative value, and the angle of the ΖΟΥ plane on the right side of the Ζ axis is defined as a positive value, and on the left side of the lens 20, the light is output. The light intensity first increases from the central axis Ζ (Ζ axis) to the left side and reaches a maximum at a (-22. 5°), then decreases again and decays to a weaker level at b (-45°). At c (- 098134065 Form No. A0101 Page 9 / 23 pages 0982058316-0 201113473 6 7. 5 °) The attenuation is at a very weak level and continues to decay to zero. On the right side of the lens 20, the output light intensity always keeps decreasing toward the right, and the light intensity at d (22.5°) is only 1/2 of the light intensity at a, at e (45°). The light intensity at time is also less than the light intensity at b. Referring to the solid line 43 and FIG. 4 of FIG. 6, the angle of the ZOX plane on the front side of the z-axis is defined as a negative value, and the angle of the ZOX plane on the rear side of the z-axis is defined as a positive value, and the light shape on the front and rear sides of the lens 20 is substantially Symmetry, the light intensity increases from the central axis I (z axis) in the forward and backward directions and reaches a maximum at g (about -60°) and at h (about 60°), and then decreases to zero. [0015] As shown in FIG. 7, when the light-emitting diode module 1 is mounted on the street light 31 (32) for road illumination, most of the light of the light-emitting diode 10 is concentrated toward the road 34 due to the lens 20. One side of the center line 342 is emitted, so that the mounting inclination angle α of the mounting arm 33 of the street lamp 31 (32) can be reduced to meet the requirements of the national standard for mounting the inclination angle α, and the light emitted from the light-emitting diode 10 can be effectively utilized. .
