Description
Technical Field
The invention relates to the technical field of vehicle illumination, in particular to a car lamp module.
The invention also relates to a car lamp comprising the car lamp module.
The invention also relates to a vehicle comprising the vehicle lamp.
Background
In the technical field of vehicle illumination, a vehicle lamp module generally refers to a low beam and/or high beam illumination module in a vehicle headlamp, and an optical part of the vehicle lamp module comprises a light source, a primary optical element and a secondary optical element, wherein the primary optical element comprises a reflector, a condenser and the like, and the secondary optical element is generally a lens.
In recent years, the application of the distributed light source in the car lamp module is more and more researched, and the product application is more and more. The scattered light source means that the light source of the low beam and/or the high beam of the car light is scattered into a plurality of light sources which are arranged on the same circuit board or different circuit boards, and the low beam and/or the high beam illumination of the car light is realized by matching with a specific primary optical element and a secondary optical element. In the distributed light source, after the light sources serving as the heat generating sources are separated, the heat sources can be dispersed at a certain space distance, so that the heat is dispersed, and the heat dissipation is facilitated. Therefore, the heat dissipation performance of the car lamp is greatly improved due to the arrangement of the distributed light sources, and the application of the distributed light sources in the car lamp module is gradually increased.
The low beam lighting mode is an important lighting mode in car light lighting, and can enable a driver to have good near field visibility under the conditions of no street lamp and low-speed running. In order to enable a driver to observe road conditions on both sides in front of a vehicle, it is necessary that the left and right sides of a low beam shape formed by a lamp module have a large widening angle, and in the art, the widening angles on the left and right sides of the low beam shape are generally designed to be about 40 ° and preferably greater than 40 °.
Further, the invention patent of China with the application number 201610679925.2 discloses an LED light source car lamp module which adopts a distributed light source and can realize the functions of single low beam and integrated high beam and low beam. Specifically, as shown in fig. 1, the LED light source lamp module in the prior art includes a low beam condenser 100, a lens 200, a lens collar, a radiator, and a low beam LED circuit board; the low beam condenser 100 is a primary optical element of the LED light source lamp module and is used for forming a low beam shape; the primary optical element includes a primary optical element body 300, and a plurality of light-entering portions 400 (i.e., low beam condensing structures) disposed at the rear end of the primary optical element body 300, wherein the light-entering portions 400 are sequentially arranged along the left-right direction, each light-entering portion 400 corresponds to one light source, so that the plurality of scattered light-entering portions 400 correspond to a plurality of scattered light sources.
In the above-mentioned car light module with the distributed light sources, the light sources sequentially arranged at the left and right ends of the central axis of the lens 200 and the light incident portions 400 of the primary optical element matched with the light sources sequentially form the middle portion and the outer portion of the light shape of the car light respectively. Specifically, taking the low beam lamp module as shown in fig. 1 and 2, for example, the middle light source and the light incident portion 400 matched with the middle light source in the view of fig. 1 form a middle portion of the low beam shape shown in fig. 2, the left light source and the light incident portion 400 matched with the middle light source in the view of fig. 1 form a right portion of the low beam shape shown in fig. 2, and the right light source and the light incident portion 400 matched with the right light source in the view of fig. 1 form a left portion of the low beam shape shown in fig. 2. Thus, the leftmost light source in the view of fig. 1 and the light entrance portion 400 matched therewith form the rightmost portion of the low beam light shape shown in fig. 2, and the light shape of the rightmost portion is shown in fig. 3, as can be seen from fig. 3: the widening angle is smaller.
Further, when the left and right side widening angles of the low beam shape formed by the lamp module are small, the widening angles can be increased by: in the first mode, a light source and a light inlet part matched with the light source in a primary optical element are additionally arranged on the left side and the right side of the car light module so as to increase the left-right side widening angle of a dipped beam light shape formed by the car light module; in the second mode, the light sources on the left and right sides and the light incident portion of the primary optical element, which is matched with the light sources, are moved outwards along the left and right directions, as shown in fig. 4, so that the light emitted by the light sources on the left and right sides irradiates a large angle range, and the left and right widening angles of the dipped beam shape formed by the vehicle lamp module are increased, as shown in fig. 5 and 6. The leftmost light source and the light inlet part matched with the leftmost light source in the view of fig. 4 form the rightmost part of the low beam light shape shown in fig. 5, and the low beam light shape of the rightmost part is shown in fig. 6; comparing fig. 3 with fig. 6, it can be seen that: the widening angle of the low beam profile shown in fig. 6 is larger than that of the low beam profile shown in fig. 3. The two modes of increasing the widening angles of the left side and the right side of the dipped beam shape can increase the size of the primary optical element in the left-right direction, so that the occupied space of the primary optical element in the left-right direction is increased, and the size and the occupied space of the car lamp module in the left-right direction are correspondingly increased. In addition, the primary optical element and the circuit board matched with the primary optical element are increased in size, so that the cost of the car lamp module is high.

Similarly, the number of the left light entrance portions 41L may be one or a plurality of; the number of right light entering portions 41R may be one or a plurality of.
Hereinafter, a preferred embodiment of the lamp module will be described, taking as an example a lamp module including a left reflecting portion 31L, a right reflecting portion 31R, a left light incident portion 41L, and a right light incident portion 41R, and the number of the left light incident portion 41L and the right light incident portion 41R is one.
In the lamp module according to the present application, the edge light entrance 41 is inclined because the edge light entrance 41 needs to emit light. Therefore, the optical axis of the edge light entering portion 41 is also inclined, specifically, the optical axis of the edge light entering portion 41 is inclined so as to be closer to the edge reflecting portion 31 which is next thereto as going forward; based on this, the optical axis of the left light entrance portion 41L extends obliquely leftward and forward, and the optical axis of the right light entrance portion 41R extends obliquely rightward and forward. And the optical axes of the plurality of intermediate light-entering portions 42 are all inclined so as to be closer to the optical axis of the secondary optical element 50 as going forward. When the car light module works, at least a part of the light rays emitted by the light source 10 matched with the left light inlet part 41L can be emitted to the left reflecting part 31L, reflected by the left reflecting part 31L, emitted from the primary optical element 20 and finally emitted to the secondary optical element 50, so as to form a car light shape with a larger right widening angle; similarly, at least a part of the light emitted from the light source 10 cooperating with the right light incident portion 41R is incident on the right reflecting portion 31R, reflected by the right reflecting portion 31R, then emitted from the primary optical element 20, and finally incident on the secondary optical element 50, so as to form a light shape of the vehicle lamp having a large left widening angle.
Further, when there is one and only one of the left light entering portions 41L, the positions of the left reflecting portion 31L and the left light entering portion 41L in the primary optical element 20 may be set by: first, according to the requirement of the right widening angle of the light shape of the vehicle lamp to be achieved, the leftmost light entrance part 400 of the conventional primary optical element 20 in fig. 4 and the light source 10 matched with the light entrance part are moved to the right, as shown in fig. 8, the moved light entrance part 400 is defined as a left virtual light entrance part 61L, and the inclination angle of the left virtual light entrance part 61L is adjusted so that the angle of the light direction emitted by the left virtual light entrance part 61L can meet the requirement of the right widening angle of the light shape of the vehicle lamp to be achieved. Second, the left virtual light-entering portion 61L has one, which simultaneously constitutes the innermost virtual light-entering portion of the left closest to the middle of the primary optical element 20; a reflection portion which extends straight forward and backward next to the left virtual light entering portion 61L is provided on the right side of the left virtual light entering portion 61L near the middle of the primary optical element 20, and as shown in fig. 8, the reflection portion is one edge reflection portion 31 on the left side, that is, the left reflection portion 31L of the primary optical element 20 is obtained.
