Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a light-emitting element, and more particularly to a light-emitting diode module. [Prior Art] [0002] As an emerging light source, the light-emitting diode has been widely used in various fields because of its high luminous efficiency, small volume, light weight, and environmental protection, and has a tendency to replace the previous light source. [0003] A conventional light-emitting diode street lamp includes a lamp housing, a plurality of light-emitting diodes mounted in the lamp housing, and a lamp cover fixed to the lamp housing and covering the light-emitting diodes. Street lights are usually installed on one side of the road, so that the light-emitting diode 'lSiW-3: ϊ: .M. i?.;: adjust l: d spirit.丨+' The light emitted by the body can illuminate a designated area on the road. The street lamp is usually provided with a reflector that cooperates with the light-emitting diode. However, since the light intensity near the optical axis of the light-emitting diode is large, the light-reflecting plate has a good light for a large angle of the light-emitting diode from the optical axis: the reflection effect is small, and the light adjustment effect near the optical axis is small. . Therefore, the reflector cannot properly adjust the light shape of the entire light emitting diode, and it is difficult to meet the actual lighting demand. [0004] In view of the above, the present invention aims to provide a light emitting diode module. group. [0005] A light-emitting diode module includes a light-emitting diode and a lens disposed on the light-emitting diode, the light-emitting diode has an optical axis, and the lens includes an a light incident surface adjacent to the light emitting diode and a light emitting surface opposite to the light incident surface, wherein the light emitting surface is symmetric with respect to a first plane perpendicular to the optical axis and the second plane, respectively The 098140556 Form No. A0101 Page 4 / Total 19 Page 201118313 [0007] [0008] [0009] [0009] 098140556 In a plane, the rays emitted from the light exit surface are symmetrically distributed The light rays emitted from the light exit surface are symmetrically distributed within a range deviating from the optical axis by 0-75 degrees with respect to the optical axis deviating from the range of 〇_45 degrees. In the light-emitting diode module of the embodiment of the present invention, the light-emitting surfaces of the lenses are respectively symmetric with respect to the first plane perpendicular to the optical axis and the second plane, so that the light-emitting diodes are emitted. The light rays are symmetrically distributed with respect to the optical axis thereof after being emitted through the light exit surface. In addition, in the first plane, the rays emitted from the light exit surface are symmetrically distributed within a range of 0-45 degrees from the optical axis, and in the second plane, the rays emitted from the light exit surface are symmetrically distributed in the relative light. When the axis deviates from 0-75 degrees, such a light-shaped distribution can cause the illuminating diode module to have no glare effect. [Embodiment] Hereinafter, a light-emitting diode module of the present technical solution will be described in detail with reference to the accompanying drawings and embodiments. As shown in FIG. 1 , a light-emitting diode module according to an embodiment of the present invention includes a light-emitting diode 10 and a light-emitting diode Γ0. A lens 20. - Referring to Figures 2 and 3, the lens 20 is made of poly(meth) methacrylate (PC) or other material having good light transmission. The lens 2A includes a support portion 21, a light guiding portion 22, and a connecting portion 23 connected between the supporting portion 21 and the light guiding portion 22. The light guiding portion 22 includes a light incident surface 24 adjacent to the light emitting diode 1〇 and a light emitting surface 25 opposite to the front surface 24. When the light emitting diode module is operated, the light emitted by the light emitting body 10 is from The light-incident surface 24 enters the lens 20, and the lens 20 is emitted from the surface of the light-emitting sheet A0101, page 5/total page 0982069617-0, 201118313. Under the common guidance of the light incident surface 24 and the light exit surface 25, the lens 20 adjusts the light emitted by the light emitting diode 10 to achieve a reasonable light shape. The light-emitting diode 10 has an optical axis I, and the light-emitting surface 25 is symmetric with respect to the first plane perpendicular to the optical axis I and the second plane, so that the light emitted from the light-emitting diode 10 is emitted from the light-emitting surface 25 Symmetrical light shape. The first plane is the plane along the center of the width direction of the lens 20 shown in Fig. 2; the second plane is the plane of the center section along the length direction of the lens 20 shown in Fig. 3. [0011] The light-emitting surface 25 includes a free-form surface 251 located at the center and an ellipsoidal surface 252 located on the left and right sides of the free-form surface 251. The free-form surface 251 is an axisymmetric structure whose width decreases from the front and rear sides toward the middle. The freeform surface 251 includes a concave arc segment 2511 at the center and two convex arc segments 2512 connected to both ends of the concave arc segment 2511. The two ellipsoidal surfaces 252 are symmetrically located on opposite sides of the free curved surface 251, and each of the ellipsoidal surfaces 252 includes a straight edge that is in contact with the connecting portion 23 and is connected to the edge of the concave arc segment 2511 and the second convex arc segment 2512 of the free curved surface 251. Curve edge. The concave arc segment 2511 of the free curved surface 251 is slightly concave with respect to the convex arc segments 2512 on both sides thereof. Therefore, the width of each ellipsoidal surface 252 is first increased from the front and rear sides toward the middle portion and then decreased to the same width. [0012] The light incident surface 24 is a concave curved surface which is concave from the central portion of the top surface of the positioning groove 210, and its axis coincides with the optical axis I of the light emitting diode 10. In addition, in order to match the light-emitting diodes 10 of different structures or to make the light distribution from the lens 20 more reasonable, a spherical surface 26 may be recessed at the top of the light-incident surface 24. [0013] It can be understood that the light exit surface 25 of the lens 20 in the LED module of the present embodiment is not limited to the combined structure of the ellipsoid surface 252 and the free curved surface 251, and the light incident surface 24 is not limited to a free curved surface. The predetermined change and trimming is also 098140556 Form No. A0101 Page 6/19 pages 0992069617-0 201118313 It is feasible that the light emitted through the lens 20 has the luminous effect in the above embodiment. Of course, the center of the light-incident surface 24 may also deviate from the optical axis I' of the light-emitting diode 10 so that the light emitted from the light-emitting diode 10 is emitted from the lens 2 and distributed reasonably. [0014] The support portion 21 and the connecting portion 23 are provided to facilitate the cooperation of the light guiding portion 22 with the light emitting diode 10 and the mounting of the lens 2 and other components such as a circuit board, so that the 'support portion 21 and the connecting portion 23 The structure is not limited. In this embodiment, the bottom surface of the support portion 21 is a flat surface, and the top surface of the connecting portion 23 is a plane, so that the front surface 25 of the light guide portion 22 of the lens 20 is mounted symmetrically about the optical axis I of the light-emitting diode 10. The structure is for conveniently positioning the position of the light-emitting diode 10 at the light guiding portion 22, so that the light-emitting surface 25 and the light-emitting diode 1's optical axis j \r-.:: :;>:?:. ο [0015] Coincident, and in order to facilitate the installation of the subsequent lens 20, the support portion 21 and the connecting portion 23 are all arranged in a regular geometry. In this embodiment, the support portion 21 and the connecting portion 23 are each a rectangular parallelepiped, the area of the connecting portion 23 is smaller than the area of the supporting portion 21, the connecting portion 23 is formed on the top surface of the supporting portion 21, and the connecting portion 23 is concentric with the supporting portion 21. Settings. The light guiding portion 22 is formed in a central region of the upper surface of the connecting portion 23, and therefore, the supporting portion 21, the light guiding portion 22, and the connecting portion 23 are disposed in the same center, that is, the central axes of the three and the light emitting diode 10 The optical axes I coincide. As shown in FIG. 4, a central portion of the bottom surface of the support portion 21 defines a positioning groove 210' for accommodating the light-emitting diode 10, and has two opposite long walls 211 and two short walls 212. Each of the long walls 211 forms an inwardly projecting lead angle with its adjacent short wall 212. An arcuate portion is recessed outwardly in the middle portion of each of the long walls 2U. Similarly, an arcuate portion is recessed outwardly in the middle portion of each of the short walls 212. The positioning slot 210 can be configured to match the LEDs 10 of different package shapes, and 098140556 Form No. A0101 Page 7 of 19 0982069617-0 201118313 The LEDs 10 can be placed in the positioning slot 210 arbitrarily. In this embodiment, referring to FIG. 2 and FIG. 3, the light-emitting diode 10 has two opposite short end faces 110 and two long end faces 120. The two short sides of the light-emitting diodes 10 are in contact with the two short walls 212 of the positioning groove 210, that is, the two short end faces 110 of the light-emitting diodes 10 are in contact with the two short walls 212 of the positioning groove 210, and the positioning grooves 210 are The four lead ends abut against the two long end faces 120 of the light emitting diode 10; the two sides of the light emitting diode 10 are spaced apart from the two long walls 211 of the positioning groove 210 along the two sides in the width direction thereof, that is, the two long end faces 120 and the two long walls 211 are mutually Not in contact. The optical axis of the light-emitting diode 10 and the optical axis of the light-emitting diode 10 installed in the positioning groove 210 [0016] When the light-emitting diode module of the present invention is operated, the light emitted from the light-emitting diode 10 is from the lens The light exit surface 25 of 20 is symmetrically distributed with respect to the optical axis I of the light emitting diode 10. The distribution of the light emitted through the light exit surface 25 will be specifically described with reference to Fig. 5 . 5 is a polar coordinate light curve (also referred to as a light intensity distribution curve) of the light emitting diode module, which includes two light distribution curves in the cross section shown in FIG. 2 and FIG. 3, wherein the broken line represents the curve Corresponding to the cross section shown in FIG. 2, that is, the light distribution curve of the first planar light emitting diode module; the curve indicated by the solid line corresponds to the cross section shown in FIG. 3, that is, the matching of the second planar light emitting diode module Light curve. In Fig. 5, a plurality of concentric circles indicate the light intensity distribution of the light emitted by the LED module, and the light intensity on the same circle is equal, and the center of the self-concentric circle gradually increases in intensity from the inner and outer circles. A plurality of radial lines drawn from the center of the concentric circle indicate the angle at which the light is off the optical axis I. It can be understood that the light intensity value in FIG. 5 does not have much significance. When the quantity/power of the light-emitting diode 10 changes, the specific value thereof changes accordingly; and the transmission through the lens 20 deviates from the optical axis I by different angles. Light 098140556 Form No. A0101 Page 8/19 pages 0992069617-0 201118313 [0017] G [0019] The distribution of relative light intensity is highlighted in Figure 5. Referring to the curve indicated by the broken line in Fig. 5, the light intensity emitted by the light-emitting diode module is substantially symmetrically distributed with respect to the optical axis 1 in the first plane. After the light emitted by the light-emitting diode 10 is emitted through the lens 20, the peak light intensity appears within about 30 degrees from the optical axis I, and the light intensity variation of the light within a range of -15 degrees from the optical axis I is small. And are higher than the light intensity in other angle ranges. Deviating from the optical axis I within the range of 15-45 degrees, the greater the angle from the optical axis I, the smaller the light intensity of the light. When the angle of the light is about 45 degrees from the optical axis, the light intensity tends to zero. Referring to the curve indicated by the solid line in FIG. 5, the light emitted by the LED module is substantially symmetrically distributed with respect to the optical axis in the second plane. After the light emitted from the light-emitting diode 10 is emitted through the lens 2, the intensity of the ridge value appears in the range of about 60 degrees from the optical axis I, and within the range of 〇45 degrees from the optical axis I, the light-emitting diode The greater the angle at which the light emitted by the body 1 deviates from the optical axis, the greater the light intensity. In the range of the partial y-axis, the light emitted from the LED 10 is larger with respect to the optical axis, and the light intensity is smaller. When the light is off the optical axis by about 75 degrees, the light intensity tends to zero. It can be understood that the “first plane” and the “second plane” of the present embodiment are not part of the light-emitting diode module, and are used for analyzing the light-emitting diode module for road illumination. 2 〇 deflection of the light, the first plane is a plane across the width direction of the road and passing through the optical axis I of the light-emitting diode 10; the second plane is perpendicular to the first plane, coincides with the length of the road and is illuminated The plane of the optical axis I of the diode 1 , the first plane and the second plane are perpendicular to the road surface at the same time. Therefore, the above 098140556 form. No. A0101, page 9 / 19 pages 0992069617-0 201118313 The light distribution curve of the first in-plane light-emitting diode module shows the light-emitting diode module along the width of the road. The light intensity distribution; the light distribution curve of the second planar light-emitting diode module shows the light intensity distribution of the light-emitting diode module along the length of the road. [0020] The light-emitting surface 25 of the lens 20 in the light-emitting diode module is symmetrically arranged with respect to the optical axis I of the light-emitting diode 10, and the light generated by the light emitted from the light-emitting diode 10 is emitted through the light-emitting surface 25 The shape is symmetrically distributed with respect to the optical axis I. Specifically, in the width direction of the road, the light intensity is symmetrically distributed with respect to the optical axis I of the light-emitting diode 10, and the specific application effect depends on the mounting method of the light-emitting diode module. When the light-emitting diode module is installed directly above the middle of the road width, the entire road width area can be reasonably illuminated. When the LED module is installed between two roads, the size, luminous power and other parameters of the LED module can be adjusted, and the LED module can simultaneously illuminate the entire width of the two roads. In the direction of the length of the road, the light intensity is symmetrically distributed with respect to the optical axis I of the light-emitting diode 10, and the light intensity of the light-emitting diode module along the two sides of the road length direction can be illuminated by the same light intensity. [0021] Further, in the first plane, the light rays emitted from the light exit surface are symmetrically distributed within a range of 0-45 degrees from the optical axis, and in the second plane, the light rays emitted from the light exit surface are symmetrically distributed. It is within a range of 0-75 degrees from the relative optical axis. Generally, the light of the LED module is more likely to generate glare in the range of 80-90 degrees from the optical axis, and the light generated by the LED module of the embodiment is substantially distributed in the range of 0-75 degrees. Inside, so there is no glare effect. [0022] In summary, the present invention complies with the requirements of the invention patent, and submits a patent application according to law.
