Field of the Invention This invention relates to a light-emitting device, and more particularly to an illuminator coupled to an optical lens that directs light substantially perpendicular to a longitudinal axis. This longitudinal axis passes through one of the horizontal surfaces of the illumination device. [Prior Art] Fig. 1 shows a conventional light emitting diode (LED) package comprising an optical lens, a package base, and an LED die 13. The LED package 10 has a longitudinal axis 15 that passes through the center of the optical lens. The LED die 13 is disposed on the package base 12. The package base 12 can have a cup (not shown). The cup can also have a reflector (not shown) to reflect light emitted from the bottom and sides of the LED crystal 13 toward the viewer. Optical lens 11 is coupled to LED die 13 to receive and direct light from LED die 3 . The optical lens 11 has a recess 14 for receiving the LED die i3. The light passing through the pockets 丄* may travel over two major optical paths: the first optical path LP1 is the first line from the (four) grains 13 to the surface 1102, and is totally reflected to be close to 9 degrees with respect to the longitudinal axis 15. The angle passes through the side wall 1101. The first optical path LP2 is such that light exits the side wall 1101 from the LED die 13 at an angle that will cause total reflection or reflection on the side wall 11Q, and exits the optical lens 11 at an angle substantially non-perpendicular to the longitudinal axis 15. The first optical path!^1 is advantageous for manufacturing an efficient side 1298207, but the second path may cause the observer to not see the spot. Therefore, there is a requirement for an LED package or a light-emitting device that it is desirable to connect a thin optical lens to reduce the overall size to avoid obscuring the observer's light spot, and another requirement is to provide uniform color light. LED package or illuminating device. SUMMARY OF THE INVENTION According to an embodiment of the invention, a light emitting device includes an optical member, a base, and an illuminator. The illumination system is disposed on a surface of one of the bases. The optical structure is attached to the base and/or the illuminator. The optical member has a rib-like development and a base. The flared portion includes a top wire, a wire surface, and a lower surface. The upper surface forms a concave σ of the potential-like expansion, the side surface being perpendicular to the horizontal surface of the base, which is perpendicular to the base. Further, the side surface ^ is bowed and preferably is a concave surface. The lower surface is joined to the side surface and the base. The member can be radiated symmetrically to the longitudinal axis. According to a further embodiment of the invention, the optical member extends in the longitudinal direction, preferably the soil right: said - through the longitudinal face of the optical member. Furthermore, a lens system is formed on the upper surface: ί Surface County - a corrugated surface. The transfer direction of the crucible formed on the upper surface is flattened in this longitudinal direction. The radius of the lens is preferably disposed approximately along the direction of the corrugation. 4 Precursor embodiment The illuminating device 20 of the invention-embodiment includes an optical member 21, a base cymbal and a longitudinal axis 24. The optical member 21, for example a 1298207, is permeable to the susceptor 22 to direct light entering it. The longitudinal axis 24 may or may not pass through the center of the optical member 21. Preferably, the longitudinal axis 24 is substantially perpendicular to a horizontal surface of the base 22. Figure 2B shows a cross-sectional view of the illumination device 2 of Figure 2a. The illuminant a is disposed on one surface of the susceptor 22. The illuminant 23 includes, but is not limited to, an LED die, an incandescent lamp, a fluorescent lamp, a cold cathode lamp (c〇ld Cath〇de Flu〇rescent Lamp; CCFL). And other means that can emit light and can be coupled to the optical member 21. The optical member 21 can be a separate component and can be attached to the base 22 by various means including, but not limited to, screwing, snapping, Friction fit, adhesive Bonding, thermal bonding, and ultrasonic bonding. On the other hand, the optical member 21 can be formed on the susceptor 22 and/or the illuminator 23 in a number of ways including, but not limited to, injection molding and casting. The 21 series is composed of a light transmissive material, and the light transmissive material may be a transparent material or a non-transparent material, and the light emitted by the illuminant 23 may pass through the transparent material or the non-transparent material completely or partially. But not limited to acrylic resin Uc^yliCResin), cycloolefin polymer (c〇c), polyacrylic acid (PMMA), polycarbonate (PC), polycarbonate/poly(decyl methacrylate) (PC) /PMMA), p〇iyetherimide, Fluorocarbon Polymer, and Silicone. The light transmissive material can be colored to make the optical member 21 function as the same filter. 1298207 If the illuminating device 2 is set in the air filled with the refractive index 丄, in order to generate the light field of the present, the refractive index of the optical member 21 needs to be 4 1.8. Device 2 The refractive index of the optical member η may also be a value of the above range, depending on the environment in which the crucible is placed or used. Preferably, the difference between the refractive index of the optical member U and the environment in which it is placed is between 0.45 and 0.5. As shown in FIG. 2, the optical member a includes an octagonal expansion portion and a base portion 2106. The expansion portion includes an upper surface 21〇1 which is formed on the light transmissive material to form a notch 2105 and is connected to the upper surface 21 (^2 side surface 21〇2, and connected to the lower surface 2103 of the side surface 2102. The base 21〇6 is for receiving light from the illuminator” and may have a recess 21〇7 to accommodate the illuminant 23 . The optical member 21 is adapted to direct a substantial portion of the light from the illuminator 23 away from the optical member 21 in a direction generally perpendicular to the longitudinal axis 24 or in a direction that is not directly directed toward the observer. Moreover, to avoid the formation of dark spots above the optical member 21, a small portion of the light from the illuminator 23 can be directed substantially parallel to the direction of the longitudinal axis 24 or toward the observer. The recess 2105 is used to form the upper surface 2101. Preferably, the recess 21Q5 has a sharp point which is located at the sinking of the upper surface 2101 and is directed toward the illuminator 23. The longitudinal axis 24 may or may not pass through a sharp point. A reflective material or a reflective structure may be formed on the recess 2105 to reflect light traveling to the upper surface 2101. The reflective material or the reflective structure includes, but is not limited to, Ag, Al, Cu ' Au, Cr, a reflective coating, and a dispersed Bragg Reflector (DBR). The anti-UV material may be formed on the recess 21 〇 5 The parts in the protection device, especially those sensitive to UV 298207 light, are prevented from being deteriorated by ultraviolet light. The upper surface 2101 is designed as a TIR surface for reflecting light entering from the base 21〇6 and preventing it from exiting by the recess 2105. Even so, there may be portions specific to Light incident at the incident angle passes through the upper surface 2101, and this particular angle of incidence varies with the overall design of the illumination device 2〇. The upper surface 2101 can be a flat surface or a curved surface having a fixed radius or more than two radii. In particular, the curved surface may have a variable radius which varies with the curved path of the upper surface 21〇1. Preferably, the radius of the sharp point away from the recess 21〇5 is greater than the radius near the sharp point. The side surface 2102 is coupled to the upper surface 2101 and is inclined relative to the longitudinal axis 24 for directing light to the lateral direction of the optical member 21, preferably for directing light to a direction substantially perpendicular to the longitudinal axis 24. If the normal vector of the side surface 21〇2 is at an angle of about 90 degrees to the longitudinal axis 24, a relatively high proportion of light passing through the side surface 2丄〇2 will proceed downward. However, if the side surface 2102 is inclined at an angle relative to the longitudinal axis 24, preferably, the side surface 2102 is facing upward, as shown in Figure 2B, the light traveling downward will be reduced. The side surface 21〇2 may be a flat surface, a rough surface, or a curved surface. The surface can be concave, convex, or a combination of both. The concave side surface can disperse light passing through the surface, and the convex side surface will converge the light passing through the surface. Rough surfaces can scatter light. The lower surface 2103 is coupled to the side surface 2102 and the base 2106. The upper surface 2101, the side surface 2102, and the lower surface 2!〇3 form a flared 1298207-like expansion portion above the base 2106. A concave surface 21〇4 may be formed between the lower surface 2103 and the base 2106. The light from the illuminator 23 to the concave surface 2104 may be reflected toward the area of the recess 21 q 5 , so that the amount of light emitted through the recess 2105 can be increased. If so, the observer will not easily observe the dark spots occurring above the notch 2105 of the optical member 21 of the light-emitting device 20. A recess 2107 can be formed in the base 2106 to accommodate the illuminator 23. The shape of the recess 2107 is preferably formed into a conical shape or a pyramidal shape. The sharp point of the cone or pyramid can point to the sharp point of the notch 21〇5. The deck 2108 of the base 2106 can be a horizontal surface, a curved surface, or a beveled surface. The light rays may be refracted by tilting at an angle to advance substantially perpendicular to the longitudinal axis 24. Figure 2C is a cross-sectional view showing an optical member 22 in accordance with a preferred embodiment of the present invention. In order to make the face clear, part of the outline and label in Fig. 2C will be omitted. As shown in Fig. 20, the optical member 21 assumes that the radiation is symmetrical to the longitudinal axis 24, and preferably has a diameter of ^1〇5 faces and a height Η of I4 dirty. The angle of the cusp of the notch 2105 can vary between two difficulties, wherein Α1 is 30 degrees and Α2 is 180 degrees, preferably Αι is 50 degrees and Α2 is 145 degrees. The angle A3 between the side surface 2102 and the longitudinal axis 24 can vary between 5 degrees and 2 degrees. The angle Μ of the cusp 2107 can vary within 180 degrees, preferably between 9 and 14 degrees. The slope Α 5 of the table 2108 can vary within 60 degrees, preferably within 1 degree. The radius R1 of the side surface 2102 can vary within 2 ,, preferably within 1 〇 mm. The radius R2 of the concave surface 21〇4 can be varied within 1 〇. The above dimensions can vary with the optical components

The light trace L2 is emitted from the emission point P, and is refracted by the concave surface 21〇4 and the upper surface 21〇1 after two times of total reflection, and is horizontally separated from the optical member η. The light trace L3 is emitted from the emission point P toward the slope of the mesa 21〇8 and is refracted to horizontally exit the optical member 21. The shape of the optical member 21 may be elliptical, circular, or rectangular from the top view. If the optical member 21 exhibits a radial symmetry with respect to the longitudinal axis 2 through the center of the optical member 21, the shape of the optical member 21 in the upper view is circular. At this point, the longitudinal axis 24 will pass through the sharp point of the notch 21〇5. If the optical member 21 is symmetrical with respect to the longitudinal plane dividing the optical member 21 into two identical portions, the shape of the optical member 21 in the upper view may be elliptical, circular, or rectangular.

The epoch 30 of the present embodiment includes the wire member 31, the susceptor 32, the illuminator 33, and the longitudinal sand. The optical member Qiu has a cross section with the above-mentioned silk fine coffee. The relationship between the optical structure and the optical member 2! is that the optical member (10) is formed on the _-axis 35 and passes through the longitudinal surface. The longitudinal direction 35 is perpendicular to the cross section of the optical member 31. The longitudinal plane % may or may not pass through the line of the optical member 31, preferably, the body is perpendicular to one of the base planes.
