As shown in FIG. 2B, each of the light-emitting diodes 22 may have a light-emitting diode die 221 and a primary lens 222, and the primary lens 222 is disposed on the light-emitting diode die 221. It is worth mentioning that when the LEDs 22 are packaged into a package by the LED die 221, as an optoelectronic component, an optical design is first performed, that is, a primary lens 222 is formed (for example, illumination). The sealing body of the diode 22 may be made of silicone or epoxy resin, and the range of the light exiting angle, the light intensity, the luminous flux 201105902, the light distribution, and the color temperature of the light-emitting diode 22 are determined. Generally, the high-power light-emitting diode 22 has an optical design angle of about 120 degrees after one optical design. The so-called secondary lens in the present embodiment refers to the light that passes through the primary lens of the light-emitting diode 22, and then changes its optical performance through an optical lens (ie, the secondary lens 23 of the embodiment) (for example, Light angle). Of course, the primary lens 222 can also be integrally formed with the secondary lens in a different design. In other words, the secondary lens 23 is directly processed on the primary lens 222, and the secondary lens 23 is formed, for example, on the sealant of the light-emitting diode 22. In addition, in general, the shape of the secondary lens 23 can be designed to change the shape according to the specification requirements of different products. In the present embodiment, the shape of the secondary lens 23 may be a lens having a short axis of 50 degrees and a long axis of 130 degrees, or a lens having a short axis of 60 degrees and a long axis of 120 degrees, so that the light emitting diode 22 is made of the secondary lens 23 The emitted light shape is formed into an asymmetrical light shape. The shape of the bottom surface of the secondary lens 23 may be substantially circular, square, rectangular, pentagonal, or hexagonal, or other polygonal shape, and the shape of the lens portion 231 of the secondary lens 23 may be hemispherical, regular cube, or rectangular. Cubes, or other polyhedra. Here, the shape of the bottom surface of the secondary lens 23 is substantially rectangular, and the shape of the lens portion 231 is substantially rectangular (the surface is a curved surface), which is not limited. Of course, different design methods may be used according to different requirements. As shown in Fig. 2C, the shape of the bottom surface of the secondary lens 23a may be substantially hexagonal, and the shape of the lens portion 231a is substantially a rectangular cube (the surface is a curved surface). Referring to FIG. 2B and FIG. 2C again, in the present embodiment, each of the second 201105902 lenses 23, 23a may further have a concave portion 232, 232a, and each of the light emitting diodes 22 is received in the concave portions 232, 232a. The shape of the concave portions 232, 232a may be, for example, a semi-cylindrical shape, and the major axis direction D1 of the concave portions 232, 232a and the longitudinal direction D2 of the lens portions 231, 231a of the secondary lenses 23, 23a may be substantially vertical. . Furthermore, as shown in FIG. 2A, FIG. 2B and FIG. 2C, each of the secondary lenses 23, 23a may further have a plurality of first fixing portions 233, 233a, 233b, and the circuit board 21 has a plurality of second fixing portions 211, 211a respectively The first fixing portions 233, 233a, and 233b corresponding to the secondary lenses 23, 23a are corresponding. The first fixing portions 233 and 233a and the second fixing portions 211 and 211a may be a convex portion and a concave portion, a hook and a card slot, or a combination of an opening and a screw hole. Therefore, the secondary lenses 23, 23a can be bonded, or snapped, or locked, or fitted to the circuit board 21, and the light-emitting diodes 22 are interposed between the secondary lenses 23, 23a and the circuit board 21. between. Here, the first fixing portions 233, 233a, and 233b and the first and second fixing portions 211 and 211a are respectively described as a combination of a convex portion and a concave portion, and an opening and a screw hole. Thereby, the secondary lenses 23, 23a are engageable (the first fixing portion 233a of the convex portion is engaged with the second fixing portion 211a of the concave portion) and then locked (for example, using a screw to pass through the opening) A fixing portion 233, 233b is coupled to the second fixing portion 211 which is a screw hole in the circuit board 21, however, it is not limited. Referring to FIG. 2A, the reflector member 24 is partially disposed around the LED body 22. The reflector member 24 can be, for example, a metal material or a plastic material coated with a reflective layer or a glass material coated with a reflective layer. The stamping process or shot 201105902 is shaped to create a plurality of recesses 241 having a perforation, and the LEDs 22 are received in the perforations of the recesses 241. In other words, a recessed portion 241 surrounds a light-emitting diode 22. The shape of each recessed portion 241 may be, for example, a circle, an ellipse or a polygon, and the polygon may be, for example, a square, a rectangle, a pentagon, or a hexagon, or a combination thereof. In the present embodiment, the shape of each recessed portion 241 is a rectangle, which is not limited. The lateral light emitted from the secondary lens 23 can be reflected upward by the reflector 24 to increase the light utilization efficiency of the light-emitting diode module 2. Further, by the design of the shape of the depressed portion 241, the light shape of the light-emitting diode emitted from the secondary lens 23 can be finely adjusted. For example, the recessed portion 241 may have an annular wall surface or a plurality of wall surfaces, wherein the lengths of the wall surfaces may be different, for example, the recess portion 241 has a long side wall surface P1 and a short side wall surface P2. The long side wall surface P1 and the short side wall surface P2 of the recessed portion 241 are different from the main plane P3 of the reflector 24 to further finely adjust the light shape of the light-emitting diode 22 from the secondary lens 23. In the present embodiment, the angle between the long side wall surface P1 of the recessed portion 241 is larger than the angle of the short side wall surface P2. For example, the angle between the long side wall surface P1 and the main plane P3 of the reflecting member 24 is 60 degrees; the short side wall surface P2 The angle with the main plane P3 of the reflecting member 24 is 45 degrees, but it is not limited. It is worth mentioning that, as shown in FIG. 3, it is another schematic diagram of the LED module 2a according to a preferred embodiment of the present invention. Corresponding to different requirements, the reflecting member 24a may not be integrally formed as in the previous embodiment, and the plurality of reflecting members 24a are separated from each other and respectively disposed corresponding to the respective light emitting diodes (not shown in Fig. 201105902) and the secondary lens 23. Of course, the design of the reflective member 24a is not limited 'for example, the reflective member 24a may not be rectangular' but is square, circular or other polygonal shape to enable fine adjustment of the light-emitting diode (not shown) by the secondary lens 23 The light shape of the emitted light is the main consideration.

Please refer to FIG. 4, which is another schematic view of a light-emitting diode module 2b according to a preferred embodiment of the present invention. The circuit board 21a of the light-emitting diode module 2b may be hexagonal. Among them, the hexagon may be a regular hexagon or a hexagon having an unequal length. By virtue of the geometrical tight alignment of the hexagons, the illuminating samarium body module 2b can be made tighter on a limited area, even light, and at a special time. Produce the outer two to greatly increase the light-emitting diode module sand. For the product, please refer to Figure 4, Figure 5A; ? fi 4's smoke A and Figure 5B, wherein Figure 5A is the same as the x-ray one-pole module 2b And the right illuminating diagram, the illuminance distribution diagram of the eight reflective members 24b is 1:5 is the illuminating-electrode of FIG. 4 and means a set of illuminance distribution of 2b. In the case of FIG. 5A and FIG. 5B, γ*, one bit is a meter r, and the X axis and the Y axis represent a distance (a single m Z axis represents a different illuminance (unit is lux) area 201105902 domain, and The illuminance of the regions increases from bottom to top. As can be seen from Fig. 5A, the light emitted by the LEDs 22 passes through the secondary lenses 23 to form an asymmetrical shape, that is, the illuminance on the X-axis and the Y-axis. The upper distribution is asymmetrical, and the light shape has a long axis direction. Therefore, the light emitted by the LED module 2b is formed by the light emitted from each of the LEDs 22 passing through each secondary lens 23 ( For example, the lens angle of the secondary lens 23 is 50 degrees on the short axis and 130 degrees on the long axis, and the light distribution is a length asymmetric shape of about 7 meters on the X axis and about 3 meters on the Y axis. It can be seen that the light shape of the light emitting diode 22 emitted by the secondary lens 23 can be further finely adjusted by the reflecting member 24, wherein the concave portion 241b of the reflecting member 24b has a long side wall surface P1 and a short side wall surface P2. The angle between the long side wall P1 and the short side wall surface P2 and the main plane P3 of the reflecting member 24b may be equal or unequal. The long side wall surface P1 and the short side wall surface P2 of the piece 24b form an angle of 60 degrees and 45 degrees with the main plane P3, respectively, so that the overall light shape distribution of the light emitting diode module 2b is slightly concentrated toward the center, thereby finely adjusting the light emitting diode. The light shape of the body module 2b can reduce the cost and time for re-opening the secondary lens 23 of different specifications, and can adjust the shape of the concave portion 241b of the reflecting member 24b to finely adjust the light shape, thereby enabling Reducing the manufacturing cost of the manufacturer. It should be noted that the arrangement direction of the secondary lenses 23 in the LED module 2b is exemplified by the parallel direction of the long axis direction D2. It should be noted that if the LED is appropriately changed The arrangement direction of the secondary lens 23 on the module 2b (for example, the arrangement direction of the plurality of secondary lenses 23 is substantially perpendicular to the long-axis direction D2 in FIG. 2A), the entire LED 201105902 can be modified. The light-emitting shape of the group 2b is even formed into a symmetrical light shape. Please refer to FIG. 6 , which is another schematic diagram of the light-emitting diode module 2 c according to a preferred embodiment of the present invention. The bottom surface shape of the secondary lens 23a The shape of the lens portion 231a of the secondary lens 23a may be a hemispherical shape. The shape of the depressed portion 241c of the reflecting member 24c may be slightly hexagonal in shape corresponding to the shape of the secondary lens 23a and the depressed portion 241c The perforations are also hexagonal. Further, each side wall surface P4 of the depressed portion 241c has a curved surface and is equal to the angle of the main plane P3 of the reflecting member 24c, but φ is not limited. Of course, corresponding to different light-emitting shapes It is required that the angle between the side wall surface P4 of the recessed portion 241c and the main plane P3 of the reflector 24c may not be equal. Therefore, the design of the different secondary lens 23a and the reflector member 24c can increase the size of the light-emitting diode module 2c. The light-shaped shape is used to increase its application. Please refer to FIG. 7 , which is a schematic diagram of a lighting device 3 using the LED module 2 b of FIG. 4 . The lighting device 3 can be, for example, a street lamp of a road or a street, or an indoor lighting device of a promenade of a building, or an illumination device of an external courtyard, or other outdoor open space lighting device, and the lighting device 3 has The plurality of light emitting diode modules 2b. In addition, the illuminating device 3 further has a carrier 31 and a heat dissipating structure 32. The heat dissipating structure 32 is disposed on the other side of the carrier 31 with respect to the illuminating diode modules 2b to increase the illuminating diode modules. The heat dissipation effect of group 2b. Furthermore, the lighting device 3 can further have a support member P for fixing the lighting device 3 to the pole (for example, a lamp pole of a street lamp). As shown in FIG. 8, it is a schematic diagram of the lighting device 3 of FIG. 7 and its light shape 201105902. The illuminating device 3 includes a plurality of light emitting diode modules 2b. Since the secondary lens 23 has a long axis direction χ2) (as shown in FIG. 4), and the secondary lenses 23 are arranged in the same direction, the illumination can be made. The device 3 emits an asymmetrical light shape. When the illuminating device 3 is placed beside the road R, an elongated illuminating area can be produced. By replacing the conventional light-shaped illuminating device with the illuminating device 3, the pitch of the street lamp setting can be increased to reduce the number of illuminating devices 3 and reduce the cost. In summary, the LED module of the present invention has a plurality of secondary lenses respectively disposed on the respective LEDs, so that the light emitted by each of the LEDs can be formed through the secondary lenses. Symmetrical light shape. In addition, the present invention can further utilize the reflecting member to finely adjust the light shape of the light emitting diode from the secondary lens. Therefore, the LED module of the present invention can reduce the cost and time of re-opening the secondary lens of different specifications, and can adjust the shape of the concave portion of the reflector to finely adjust the light shape, thereby reducing the manufacturing cost of the manufacturer. . Furthermore, the different end products of the LED module of the present invention can also emit an asymmetrical light shape. Thereby, when the lighting device of the light-emitting diode set of the present invention is disposed beside the road, a larger illumination area can be generated to replace the traditional light-shaped circular lighting device, thereby reducing the lighting device. Set the number and reduce the cost. Furthermore, the LED module of the present invention can apply a hexagonal circuit port. The hexagonal geometry can make the emitter module of the present invention have a limited area (for example, The specially shaped luminaires are arranged in a tighter arrangement and produce the most suitable light shape, thereby greatly increasing the adaptability of the LED module of the present invention to the appearance of different end products.
