The specific meaning of the above terms in the present application will be understood in specific cases by those of ordinary skill in the art.

The car lamp assembly not only can provide illumination for the vehicle, but also can be used as a signal lamp in the running process of the vehicle so as to carry out signal interaction transmission with other vehicles. The uniformity of the light emitting surface of the car light assembly and the size of the light emitting surface have important influence on the convenience of observing the drivers or pedestrians, and the bigger and more uniform the light emitting surface of the car light assembly is, the more convenient the drivers can identify. In the related art, due to the loss of light energy in the transmission process, the light source of the car light assembly has smaller light emitting surface with higher uniformity of luminous intensity, and is inconvenient for drivers or pedestrians to observe and identify.

In view of this, the embodiment of the application provides a vehicle lamp assembly and a vehicle using the same, so as to improve the area of the light emitting surface of the vehicle lamp assembly with higher uniformity, and to facilitate the driver to observe and recognize the related signals during the running process of the vehicle.

As shown in fig. 1 and 2, the vehicle lamp assembly 10 provided in the embodiment of the application includes a light source 11 and a collimating element 12, the collimating element 12 has a light emitting surface 12a and n light reflecting surfaces 12b, and the light emitting direction of the light source 11 is configured to emit light to the light emitting surface 12a after being incident on the collimating element 12 through the light incident surface and being reflected by the n light reflecting surfaces 12b in sequence, where n is a positive integer less than or equal to 4.

Alternatively, the light source may be a halogen lamp or an LED (LIGHT EMITTING Diode) or the like.

The light emitted by the light source 11 may be divergent, and after the light emitted by the light source 11 is directed to the collimating element 12, the light is changed into parallel light through the collimating action of the collimating element 12, and the propagation distance of the light is advantageously increased, so that the light emitted by the light source 11 has better penetrability after passing through the collimating element 12, and the penetrability of the light emitted by the vehicle lamp assembly 10 is advantageously increased.

By reasonably configuring the position and angle of the light reflecting surface 12b, after the light emitted from the light source 11 enters the collimating member 12 through the light entrance member, the light sequentially irradiates the light reflecting surface 12b of the collimating member 12, and after being reflected by the n light reflecting surfaces 12b, the propagation direction of the light changes, and finally the light exits to the light exit surface 12a, so that the light emitted from the light source 11 is converted into collimated light and exits to a set direction.

The collimating element 12 has n light emitting surfaces 12a, where n is a positive integer less than or equal to 4, and optionally n may be 1, 2, 3 or 4, and the number and angle of the light reflecting surfaces 12b may be set reasonably according to the position of the light source 11 relative to the light emitting surface 12a, so as to realize that the light emitted by the light source 11 passes through the collimating element 12 and then is emitted to a specific direction by the light emitting surface 12 a. Fig. 1 shows a schematic view of a collimator 12 having two light-reflecting surfaces 12b, and fig. 2 shows a schematic view of a collimator 12 having one light-reflecting surface 12 b.

It can be understood that, if the number of the light reflecting surfaces 12b is smaller than or equal to 4, after the light emitted by the light source 11 passes through the collimation effect of the collimation member 12, the number of the light reflecting surfaces 12b is smaller than or equal to 4, which is favorable to reducing the number of times the light emitted by the light source 11 is reflected, and is favorable to reducing the propagation path of the light, further favorable to reducing the loss of light energy of the light emitted by the light source 11 in the process of passing through the collimation member 12, favorable to improving the energy when the light propagates to the light emitting surface 12a, and further favorable to improving the light emitting surface area and the light emitting uniformity of the light emitting surface 12 a.

According to the car light assembly 10 provided by the embodiment of the application, the number of the light reflecting surfaces 12b of the collimating element 12 is smaller than or equal to 4 by arranging the collimating element 12, and on the premise that the light emitted by the light source 11 is collimated by the collimating element 12 so as to improve the permeability of the emitted light of the car light assembly 10, the loss of light energy in the process of transmitting the light emitted by the light source 11 in the collimating element 12 is reduced, the brightness of the light emitted by the light emitting surface 12a and the area of the light emitted with higher uniformity are improved, and the light emitting area of the car light assembly 10 is further improved.

In some embodiments, the refractive index of the collimating element 12 is greater than the refractive index of air, and the light source 11 is configured such that the incident angle of the emitted light to the light reflecting surface 12b is greater than or equal to the critical angle for total reflection by the light reflecting surface 12 b.

When the incident light is incident on the light reflection surface 12b, refraction or reflection may occur, and when the incident angle of the incident light is smaller than the critical angle, refraction occurs on the light reflection surface 12b, and when the incident angle is greater than or equal to the critical angle, total reflection occurs.

By reasonably setting the position of the light source 11 relative to the collimating element 12 and the position and angle of the light reflecting surface 12b, the light source 11 can be emitted to the light reflecting surface 12b, and then the incident angle is always larger than or equal to the critical angle, so that the light is totally reflected after being emitted to the light reflecting surface 12b, and refraction can not occur, thereby being beneficial to further reducing the loss of light energy in the process of transmitting the light emitted by the light source 11 in the collimating element 12, and the light emitted by the light source 11 is emitted from the collimating element 12 after being reflected by the collimating element 12 without being reflected by other components, thereby being beneficial to reducing the particle sense of the light emitted by the lamp assembly 10 and improving the light emitting effect of the lamp assembly 10.

With continued reference to fig. 1 and fig. 2, in some embodiments, the collimating element 12 emits light along a first direction X on the light emitting surface 12a, and a front projection of the light emitting surface 12a along the first direction X is disposed on one side of a front projection of the light source 11 along the first direction X along a second direction Y, where the first direction X intersects the second direction Y.

The front projection of the light emitting surface 12a along the first direction X is disposed on one side of the front projection of the light source 11 along the first direction X along the second direction Y, that is, the front projection of the light emitting surface 12a along the first direction X and the front projection of the light source 11 along the first direction X are staggered, the light emitting surface 12a does not overlap with the light source 11 in any part along the first direction X, and when the vehicle lamp assembly 10 is observed along the first direction X, the light emitting surface 12a generates a suspension effect, which is beneficial to improving the technological sense and the visual impact of the vehicle lamp assembly 10. In addition, since the orthographic projection of the light-emitting surface 12a along the first direction X is disposed on the side of the orthographic projection of the light source 11 along the first direction Y, the installation component of the light source 11 does not occupy the space of the side of the light-emitting surface 12a along the first direction X, which is beneficial to saving the space of the side of the light-emitting surface 12a away from the light-emitting direction along the first direction X.

The light source 11 is located at a side of the first light reflecting surface 121b along the first direction X, and the second light reflecting surface 122b is located at a side of the light emitting surface 12a along the first direction X.

In this way, the light emitted from the light source 11 is reflected by the first light reflecting surface 121b and the second light reflecting surface 122b in this order, and then is emitted to the light emitting surface 12a, and is emitted from the light emitting surface 12 a.

The light source 11 and the first light reflecting surface 121b are arranged along the first direction X, the light emitting surface 12a and the second light reflecting surface 122b are arranged along the first direction X, and then the first light reflecting surface 121b and the second light reflecting surface 122b are arranged along the direction intersecting the first direction X, which is favorable for reducing the size of the collimating element 12 along the first direction X, thus, being favorable for more reasonably configuring the positions of the light source 11 and the collimating element 12, reducing the space occupied by the lamp assembly 10 along the first direction X, and being favorable for reducing the propagation path of the light emitted by the light source 11 in the collimating element 12, and further being favorable for reducing the loss of light energy in the propagation process of the light emitted by the light source 11 in the collimating element 12.

In some embodiments, the light source 11 comprises an LED lamp.

The LED lamp has the advantages of high efficiency, energy saving, long service life, less harmful gas release, small volume and the like, and the light source 11 comprises the LED lamp, so that the energy consumption of the lamp assembly 10 is reduced, the lamp assembly is more energy-saving and environment-friendly, and the occupied space of the lamp assembly 10 is reduced.
