Description of the invention: 玉: [The invention belongs to the field of ray] [0001] The invention relates to a illuminating component [Prior Art] just as an emerging light source, illuminating Due to its high luminous efficiency, small size, light weight and ring material advantages, the diode has been disregarded in the current field, which has a tendency to replace traditional light sources.刚 The traditional light-emitting diode street lamp includes a light-emitting diode, a plurality of light-emitting diodes mounted in the lamp housing, and a lampshade covering the light-emitting two-pole body on the lamp housing. Since the street light is generally installed on one side of the winding road, the light emitted by the light-emitting diode must pass through the corresponding operation: the calibrated shooting area on the road meets the needs of the vehicle illumination. At present, a reflector is usually used to reflect the light of the light source so that it can be emitted toward a predetermined direction. However, since the light intensity near the optical axis of the light-emitting diode is large, the reflector can only be used for the light-emitting diode. The light is reflected off from the light of the larger angular Q-degree light of the optical axis, and it is difficult to adjust the light near the optical axis. It is impossible to adjust the light emitted by the entire light-emitting diode to the desired light shape, which is difficult to satisfy. Actual lighting needs.

The lens is recessed in the lens, and the direction of the light-emitting surface protrusion is the same as the direction of the concave surface of the light-incident surface. Compared with the prior art, the present invention uses a lens to adjust the light of the light-emitting diode, and can redistribute the light of each light intensity distribution, due to the uneven direction of the light-incident surface and the light-emitting surface. The deviation from the optical axis causes the light of the light-emitting diode to be adjusted by the lens to illuminate a wider range toward one side, and to provide concentrated illumination to the other side, thereby being suitable for lighting requirements of roads, tunnels, corridors and the like.

The refresh angle between the center money 11 and the light pumping 1 can be selected according to the needs of the specific lighting effect. In this embodiment, the angle between the optical axis 1 and the intermediate portion 263 of the light-emitting surface 200 is 30 degrees. In this embodiment, as shown in FIG. 5, since the center line 11 of the middle portion of the lens 20 is deviated from the optical axis 1, the lens 098143024 is shown in the form number A0101, page 7 / 21 pages 0982073814-0 201122358 ~ 1r 20 The surface 200 is biased to the left side of the optical axis I, and the top surface of the light-emitting surface 2〇0 is located on the left side of the first surface, and the light of the ridge light-emitting two shuttles (four) is emitted by the light-emitting surface 200 of the lens 20 The optical axis I is deflected to the left toward the center line 丨I. Thus, the lens 2 of the light-emitting diode module of the present invention adjusts the light emitted from the light-emitting diode 10 to achieve a reasonable light shape. [0015] As shown in FIG. 4, the intermediate portion 263 of the front surface 2 of the lens 20 corresponds to the top wall 224 of the light incident surface 223, and the intermediate portion 263 and the top wall 224 are the same to the optical axis I. Side tilt. In the second coordinate plane, the thickness of the portion of the lens 20 corresponding to the top wall 224 at the intermediate portion 263 is outwardly increased by the center residue 11 in the lateral width direction, both in the lateral direction and in the middle of the lens. The thickness of the portion corresponding to the top wall 224 of the portion 263 is decreased from the center. As shown in Fig. 3, in the first coordinate plane, the thickness of the portion of the lens 2 corresponding to the smooth surface 2 系 is increased outward from the center in the longitudinal direction. [0016] FIG. 6 shows a polar coordinate light distribution curve of the light emitting diode module in the cross section of FIG. 3 and FIG. 4, wherein the curve indicated by the solid line corresponds to the wearing surface shown in FIG. 3, that is, The light distribution curve of the light emitting diode module in the first plane; the curve indicated by the broken line corresponds to the cross section shown in FIG. 4, that is, the light distribution curve of the light emitting diode module in the second plane. The latitude coordinate (polar angle) of Fig. 6 indicates the angle at which the light line deviates from the optical axis I, and the longitude coordinate (polar axis) indicates the light intensity of the light. In particular, the value of the longitude coordinate in Fig. 6 only represents the relative intensity ratio of the light distribution at various angles, and does not represent the actual light intensity. Because the number/power of the field light-emitting diode 10 changes, the specific value will also Changed. After the deflection of the lens 20, the light having a different angle from the optical axis has a relative intensity distribution which is shown in Fig. 6. In the first plane, the light intensity is symmetrically distributed about the axis of the twist, the illuminating 098143024 Form No. A0101 Page 8 of 21 [0017] 201122358 The light emitted by the diode 10 is deflected by the lens 2〇, The peak light intensity appears in the t-degree of the sneak peek I, which is preferably in the range of '3'. The light intensity of the light within a range of -35 degrees from the optical axis I is gradually increased by 'and the average intensity is higher than the half-peak intensity. When the angle of the light from the optical axis I is greater than 37 degrees, the greater the deviation angle, the smaller the light intensity. When the deviation angle of the light is about 50 degrees, the light intensity tends to be paralyzed. [0018] Ο In the second plane, after the light emitted by the light-emitting diode 10 is deflected by the lens 20, its peak first appears on one side of the optical axis I and deviates from the optical axis I by 4_8 degrees. Ground, the peak of light intensity appears at 6 degrees from the axis of the optical axis. After the peak appears, the light intensity super-successive reading gradually decreases toward the direction of the optical axis I, and is offset from the optical axis by 35 degrees. The minimum value is reached to the left and right; while the light-emitting diode 1 emits light and the light is absent: the intensity peak appears on the optical axis, and is emitted on the other side of the optical axis I in the interval of 15-degrees from the optical axis. The light intensity of the polar body 10 rises sharply to a peak value from the range of the twist to -15 degrees, and corresponds to the light from the _2 degree to the , degree, and the light of the light-emitting diode 1 ', 虡J climbs to J peak, therefore, the average light intensity of the light on the other side of the axis I tends to 〇. In addition, the LED module has the following characteristics: a) in the first "the combination of the light emitted by the LED 20 is changed from the object or the road, so that the road illumination is relatively uniform; u J is the second call, and the light intensity of the light emitted by the light-emitting diode 10 is relatively concentrated, and the light-direction side deflection. It can be seen that the light-emitting diode module can obtain: a rectangular light shape with a large range of illumination in the longitudinal direction of the lens 20, a small circumference in the skin direction, and strong directivity illumination, suitable for road corridors and the like. Application of occasions. With the road 098143024 Form No. A0101 Page 9 / Total 21 page 0982073814-0 201122358 [0020] [0022] [0023] 098143024 This buckle is caused by the thickness of the left and right sides of the lens 2 If the intensity of the light is different, the one of the two must be moved, and the difference between the thickness of the left and right sides of the mirror 2 can be adjusted to adjust the overall polarizing effect of the LED module. Further, in the present invention, the plane passing through the optical axis is an imaginary plane, and the solid surface exists in the physical structure of the light-emitting diode 10 and the lens 20. The term "light-incident surface" and "light-emitting surface" as used in the present invention means that the surface through which light passes is not referred to as the "light-incident surface" and the "light-emitting surface" of the present invention. In the invention, the light-incident surface and the light-emitting surface of the lens 2 in the light-emitting diode package are not in the slope surface and the free-form surface of the upper layer, and it is also feasible to make certain changes and trimming on the basis of this. As long as the light deflected by the slow lens 20 has the light effect in the above embodiment, it is understood that although the lens 20 of the present invention is used to replace the light reflecting plate of the conventional art to illuminate the light emitting diode 10 Adjustments are made, but the use of the reflector in the conventional art with the lens 20 of the present invention is not excluded. In fact, the lens 20 and the reflector group are used more accurately < for the light-emitting diode 10 The aperture adjustment makes the output light shape more suitable for the needs of road lighting. In addition, although the light-emitting diode module in the above embodiment is exemplified for application to road lighting, it is required to be combined with the light-emitting diode module. Group light distribution curves are the same or similar The occasions also apply, such as corridors, courtyards, airport runways, etc., and the subject matter of the present invention should not be construed as being limited to road lighting.
