Fig. 12 is a illuminance distribution diagram of the composite curved type light source modulating device 2 of Fig. 7. As shown in FIG. 4, the present embodiment is a composite curved surface light source modulating device 20, comprising: a light distribution composite refractive surface 3〇; a base surface 4〇; a reflective surface 5〇, and a dimming composite Refractive surface 60. The light source modulating device 2 has a central axis 21, and the light source modulating device 20 is symmetrical to the central axis 21 to form a circular symmetrical structure or an elliptical symmetrical structure. Further, the material of the light source modulating device 2 can be made of a plastic material and can be produced by injection molding. 9 1352794 A composite light refraction surface 30 having a first refractive surface 3i and a second refractive surface 32. The light-receiving composite refractive surface 3 is used to distribute the light emitted by the light-emitting diode light source 15 into the light source modulation device 2 by the first refractive surface 31 and the second refractive surface 32, respectively. The first-refractive surface 31' is a function curved surface, and the first-refractive surface 31 can be designed as a different function curve φ according to the design. For example, the first-refractive surface 31 can be a concave function surface (such as FIG. 5, Figure 8 shows the - convex function surface (as shown in Figure 6, called Figure 9), or a plane (as shown in Figure 7, fi〇). The central axis of the surface of the first refractive surface 31 coincides with the central axis 21 of the light source modulation device 2, and the first-refractive© 31 is set to be refracted by at least _light-emitting diode light source: emit less than - light distribution reference The position of the light of the corners, where the definition of the light distribution reference angle θ will be described in detail as follows. • π, as shown in FIG. 5, through the design of the light source modulating device 20, in particular, one of the rays emitted by the light-emitting diode light source 15 can be made from the periphery of the first refractive surface 31 and the periphery of the first refractive surface 32. After the incident is incident on the light source modulating device, Lu is then exited from the light source modulating device 2' by the fourth wiring 25 (described as described later) and the light is defined as a critical ray 70. The critical angle of the light distribution is the angle between the critical ray 70 incident on the light source modulating device 20 and the normal direction of the illuminating diode source 15. The critical angle of the light distribution can range from 15 degrees to 75 degrees. The light distribution reference angle is between ±10 degrees of the critical angle of the light distribution. For example, when the critical angle of the light distribution is 15 degrees, the light distribution reference angle (9 may be an angle between 5 degrees and 25 degrees. More preferably, the light distribution reference angle g can be matched with The light critical angles are equal in size. When the light incident angle of the light emitted by the LED light source 15 is less than the light distribution reference angle ,, the light is distributed to the first refractive surface 31 and is refracted by the first refractive surface 31. Incident into the light source modulation device 20. As shown in Fig. 4 and Figs. 5 to 10, the second refractive surface 32 is an arbitrary curved surface symmetrical to one of the central axes 21. The periphery of the second refractive surface 32 and the The periphery of a refractive surface 31 is connected to form a receiving portion for accommodating the light emitting diode light source 15. The light emitting diode light source 15 can be a light emitting diode chip or a packaged light emitting diode. The light-emitting wavelength of the light-emitting diode source 15 is between 350 nm and 850 nm. ^ The second refractive surface 32 is disposed to be refracted by the light-emitting diode source 15 to be greater than the light distribution reference angle The position of the light of the ray, that is, when the light emitted by the light-emitting diode source 15 enters When the light angle is greater than the light distribution reference angle (9, the light is distributed to the second refractive surface 32, and is refracted by the second refractive surface 32 into the light source modulation device 20. The base surface 40, the peripheral edge and the second refractive The faces 32 are joined to form a first wire 22, and are also in contact with the periphery of the reflecting surface 50 to form a second wire 23. The base surface 40 has a positioning structure for enabling the light emitting diode source 15 to The positioning is fixed in the accommodating portion formed by the first refracting surface 31 and the second refracting surface 32, so that the geometric center of the illuminating diode light source 15 can be positioned on the extension line of the t-axis 21 of the light source modulating device 20, Further, the light of the light-emitting diode light source 15 is equally incident on the light source modulating device 20. The reflecting surface 50 is symmetrical with respect to one of the central axes 21 and is in contact with the base surface 40 to form the second wiring 23. The reflective surface 50 is disposed at a position capable of reflecting the light incident from the light-receiving composite refractive surface 30, and the shape of the reflective surface 50 is designed such that the light incident on the reflective surface 50 is totally reflected to the third refraction 1352794. • Face 61, meaning the shape of the reflecting surface 50 The shape needs to satisfy the condition that the incident angle of the light is greater than the critical angle when the light is incident on the reflecting surface, and the light is totally reflected by the reflecting surface 5, thereby changing the traveling direction of the light. The dimming composite refractive surface 60' has a third refractive surface 61; and a 'fourth refractive surface 62. The dimming composite refractive surface 60 is used to modulate the light reflected by the reflecting surface 50' and refracted by the first refractive surface 31. The surface design of the surface can modulate the light path of the light, thereby enabling the light of the light-emitting diode source 15 to achieve a collimating and uniform effect. The reed three-refractive surface 61 is symmetrical with respect to the central axis 21 - any The function curved surface, and the periphery of the third refractive surface 61 is in contact with the periphery of the reflecting surface 5A to form a second wiring 24' and the second refractive surface 61 is disposed at a position where the light reflected by the reflecting surface 5 is modulated. Moreover, the shape of the third refractive surface 61 is such that the incident angle of the light incident on the second refractive surface 61 is smaller than the critical angle, so that the light line is refracted by the light source modulation device and the refracted light is approximately parallel to the middle axis. 21, that is, the divergence angle of the light emitted by the second refractive surface 61 is not always small and quite collimated. The fourth refractive surface 62 is arbitrarily curved to one of the central axes 21, • it may be a convex surface, and the periphery of the fourth refractive surface 62 is connected to the third refractive surface 61: the periphery to form a fourth Wiring 25. Further, the fourth refractive surface 62 is disposed at a position capable of modulating the light incident from the first refracting surface 31, and the shape of the fourth refractive surface 62 is designed to cause the incident angle of the light incident to the fourth refractive surface 62. The boundary angle, and thus the light refracted by the first refracting surface 31, is again refracted, and the ray refracting the light source modulating device 20 is approximately parallel to the central axis 21, that is, the light emitted by the light source modulating device 2 is relatively collimated. . 12 1352794 In order to fine-tune the uniformity of the light collimation of this embodiment, the shape of the third refractive surface 61 is further designed. As shown in FIGS. 5, 6, and 7, the first distance D1 is designed to be larger than the second distance D2 (D1 > D2), and the first distance D1 is the vertical between the third wire 24 and the base 40. The distance, and the second distance D2 is the vertical distance between the fourth wire 25 and the base surface 40. Or as shown in FIG. 8, FIG. 9, and FIG. 10, the first distance D1 and the second distance D2 are both designed to be larger than the third distance D3 (D1>D3 and D2>D3), and the third distance D3 It is the vertical distance between the lowest point of the third refractive surface 61 and the base surface 40. Taking the composite curved type light source modulating device 20 of Fig. 7 as an example, it is a circular symmetrical structure. As shown in FIG. 11 and FIG. 12, it is a composite curved surface light source modulating device 20 using the ASAP (Advanced System Analysis Program) optical simulation software simulation of the American Breault Research Organization, at a distance from the light emitting diode light source 15. The spot pattern and illuminance distribution map of the plane at about 18 mm. The effective uniform range of the spot is about 15 mm in diameter, and the intensity of the illuminance is uniform, and the spot no longer has the shape of a concentric circle, that is, the composite curved type light source modulating device 20 of the embodiment has a light ray system that is relatively collimated. And the illuminance distribution is fairly average. The composite curved surface light source modulating device 20 of the embodiment has the function of making the light emitting diode light source 15 collimated and uniform, so that the light emitting diode light source 15 to be modulated can be analyzed first, and according to the required illumination distance. And the illumination range, the light distribution composite refractive surface 30, the reflective surface 50 and the dimming composite refractive surface 60 of the light source modulation device 20 are planned and designed to achieve the desired illumination distance and illumination range.
