LED composite collecting lens and its module

The present invention relates to an LED composite collecting lens structure, and more particularly to a composite collecting lens structure applied to vehicle illumination. The composite collecting lens is composed of two aspherical convex lens faces of different curvatures, each non- The spherical convex lens has a horizontal control ridge line and a plurality of vertical direction control ridge lines, and the control ridge line projects the main light area and the second light area, and the main light area meets the requirements of the international regulations of the lamp. The secondary light zone can complement the dark zone below the main light zone, and the secondary light zone can also reinforce the light intensity of the main light zone, achieving the utility of complying with the requirements of the international regulations of the lamp and the safety of night driving.

Generally used in the lens structure for vehicle illumination, most of them use a convex lens that aggregates light. The lens is a spherical lens or a parabolic lens, which is a convex lens produced by rotating a half circle or a parabola along the center 360 degrees, when the light source is emitted from the focus position. The light passing through the bottom plane into the light surface and passing through the light exit surface of the upper convex lens is a circular light type illumination area; in the international vehicle lighting specification, the light type must present a horizontal light band, and the lens cannot meet this requirement.

The structure of the prior art projection type LED lamp can be referred to the lamp disclosed in the invention patent No. I296243. The lamp includes a base and an LED light source fixed on the base with the light emitting surface facing upward and reflecting. Cover, a lampshade, a cover. When the LED light source is activated, the radiation is struck on the reflector, and the reflected light passes through the mask and the lampshade, and then the light is projected to meet the light type and intensity required by the regulations; however, the projected LED lamp structure, the light source passes through the reflector, The reflection and refraction of the mask and the lampshade, the light loss is more, and the light utilization rate is not good; the LED light source, the light-emitting surface is facing upward, which is easy to cause the generation of the residual light above the cut-off line. It becomes glare and affects the safety of driving. It is more complicated and costly to consider the accessories and assembly cost of the lamps.

The concentrating lens structure of the prior art multi-curvature composite curved surface can be referred to the Chinese Patent Publication No. 201209341. The concentrating lens structure can conform to the light type specification of the international vehicle lighting specification, but the multi-curvature composite surface set The optical lens completely collides the light emitted by the LED point light source into the light zone specified by the regulations. In the actual vehicle assembly application, the vehicle lighting fixture and the light-type intermediate part projected by the lamp will produce an obvious dark area. When driving at night, the above-mentioned dark areas cannot achieve effective illumination, which invisibly increases the risk of driving at night.

The reason is that this creation has been researched and improved in view of the above-mentioned existing lack of lighting structure. With many years of experience in the design and development of automotive lighting, it provides an LED composite collecting lens structure to achieve more practical value.

The purpose and effect of the LED composite collecting lens structure of the present invention are realized by the following technologies.

The main one is a non-spherical convex lens surface having two different curvatures at one end, and the other end is a planar lens design, and the two different curvature aspherical convex lens surfaces have a horizontal control ridge line and a plurality of vertical direction control ridge lines. The control ridge line is projected into the main light zone and the second light zone (the third picture), the main light zone meets the requirements of the international regulations of the lamp, and the secondary zone can complement the dark zone below the main light zone. The secondary light zone can also reinforce the light intensity of the main light zone (seventh image) to meet the requirements of international regulations for vehicle lights and night driving safety.
