This is done solely for the purpose of facilitating the description of the invention and simplifying the description, and is not intended to indicate or imply that the device or element so referred to must be in a particular orientation, constructed and operated, and therefore should not be taken as limiting the invention.
Furthermore, the terms "first", "second" are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated, and therefore the features defined "first", "second" may explicitly or implicitly include one or more of the features described.
Referring to fig. 1-3 and 9-17, the light condenser of the present invention includes a first light condensing unit and a second light condensing unit that are integrally formed, so as to facilitate processing and ensure the connection reliability and positioning accuracy of the whole light condenser, the first light condensing unit and the second light condensing unit are integrally formed parts, preferably integrally insert-molded parts or integrally double-colored integrally molded parts, the integrally formed design can reduce the installation structure, the structure is compact, and the installation accuracy requirement is reduced, thereby reducing the cost.
The first light-gathering unit and the second light-gathering unit are formed parts made of different materials, for example, the first light-gathering unit is a silica gel or PMMA formed part, and the second light-gathering unit is a PMMA or PC formed part, so as to obtain different refractive indexes, wherein the refractive index of the silica gel is smaller than that of PMMA (polymethyl methacrylate), and the refractive index of PMMA is smaller than that of PC (polycarbonate). The first light-gathering unit comprises a first light-entering part 11 and a first light-passing part 12, the second light-gathering unit comprises a second light-entering part 21 and a second light-passing part 22, an interface 3 is formed between the first light-passing part 12 and the second light-passing part 22, the refractive index of the first light-passing part 12 is smaller than that of the second light-passing part 22, as shown in fig. 4 and 21, after the outgoing light beam of the first light incident part 11 enters the first light passing part 12, at least part of the light can be refracted through the interface 3 into the second through-light portion 22 and exit from the second front end surface 23 of the second through-light portion 22, as shown in fig. 5 and 19, the outgoing light beam from the second light incident portion 21 can enter the second light passing portion 22 and then exit from the second front end surface 23, thus, the light beams emitted from the first light incident part 11 and the second light incident part 12 can be emitted from the second front end surface 23 to the designated area as much as possible, and further, the light loss is reduced, and the light extraction efficiency is improved.
After the outgoing light beam of the second light incoming portion 21 enters the second light outgoing portion 22, the light beam passing through the interface 3 may be caused to continuously propagate in the second light outgoing portion 22 by means of total reflection at the interface 3, and then be emitted from the second front end surface 23. Through the design of the angle between the second light incident part 21 and the interface 3, the incident angle when the emergent light of the second light incident part 21 reaches the interface 3 is larger than the critical angle, so that the emergent light of the second light incident part 21 can not be refracted through the interface 3 to enter the first light passing part 12, and can be totally emitted from the second front end surface 23, and the light loss is effectively reduced.
In order to obtain a proper optical shape, normally, the first light incident portion 11 and the second light incident portion 21 respectively have a plurality of side-by-side portions, and in order to ensure that the outgoing light of the first light incident portion 11 can enter the second light incident portion 22, as shown in fig. 11, the number of the first light incident portions 11 is smaller than or equal to the number of the second light incident portions 21, that is, the whole width of the first light incident portion 12 is smaller than or equal to the width of the second light incident portion 22 (here, the direction in which the light passes through the respective light incident portions is the longitudinal direction, and the direction perpendicular to the longitudinal direction is the width direction).

At this time, as shown in fig. 1 to 3 and 9, the first front end surface 13 of the first light passing portion 12 is coplanar with the second front end surface 23 of the second light passing portion 22; alternatively, as shown in fig. 10, when the first front end surface 13 does not need to emit light, in order to further reduce the volume, the first front end surface 13 is located on the side of the second front end surface 23 close to the first light incident portion 11, that is, the length of the first light passing portion 12 is smaller than that of the second light passing portion 22.
In addition to the above technical solutions, as shown in fig. 12, the second light passing portion 22 may also be of a bent type, in this case, the first light passing portion 12 is located at a bent position of the second light passing portion 22, and the bent position of the second light passing portion 22 forms the interface 3, so as to adapt to vehicle lamps with different spatial arrangements.
The condenser can be used in a low beam module, a high beam module and a high and low beam integrated module.
When the condenser of the present invention is applied to the low beam module, the first condensing unit is located below the second condensing unit, the outgoing light of the first light entering part 11 enters the first light passing part 12 and then can be refracted through the interface 3 to enter the second light passing part 22 and exit from the second front end surface 23, the outgoing light of the second light entering part 21 enters the second light passing part 22 and then can exit from the second front end surface 23, the low beam cut-off line structure 4 is formed on the lower edge of the second front end surface 23, and the outgoing light of the second light entering part 21 enters the second light passing part 22 and then exits from the second front end surface 23 after being totally reflected through the interface 3 and/or directly exits from the second front end surface 23.
As shown in fig. 1-3, when the light condenser of the present invention is applied to a high beam module, the first light condensing unit is located above the second light condensing unit, the emergent light of the first light incident portion 11 enters the first light passing portion 12, and then can be refracted through the interface 3 to enter the second light passing portion 22 and exit from the second front end surface 23, the light path of the light is shown in fig. 4, and the light shape projected by the lens 5 is shown in fig. 6; after entering the second light passing part 22, the outgoing light of the second light entering part 21 is totally reflected by the interface 3 and then is emitted from the second front end surface 23 or directly emitted from the second front end surface 23, the light path of the light is as shown in fig. 5, the light shape after being projected by the lens 5 is as shown in fig. 7, and the light shapes of the two parts can be overlapped to form a high-flux and high-illuminance high-beam light shape as shown in fig. 8.

The lower edge of the second front end surface 23 is formed with a low beam cut-off line structure 4. The outgoing light beam of the second light incident portion 21 enters the second light passing portion 22, and then is totally reflected by the interface 3 and then is emitted from the second front end surface 23 or directly emitted from the second front end surface 23. As shown in fig. 18, a region III light shape forming structure 221 is formed at a lower portion of the second light passing portion 22, and after the outgoing light of the second light entering portion 21 enters the second light passing portion 22, a part of the light exits from the second front end surface 23, and another part of the light can be refracted by the region III light shape forming structure 221, enter the first light passing portion 12, and exit from the first front end surface 13, so as to form a low-beam region III light shape. A 50L dark area structure 222 is formed at the front end of the lower portion of the second light passing part 22, and is used for controlling the illumination of the 50L dark area.
