Example 1

A vehicle lamp as shown in fig. 1-2, comprising: a heat dissipation substrate 200, a low beam module 300, a high beam module 400, a light cutting module 500 for switching the high beam and the low beam, a lamp lens 600 for emitting the lamp light, and a light supplementing module 100, which are arranged on the heat dissipation substrate 200; the light supplementing module 100 comprises a module housing 10 and at least one group of first light supplementing modules 20 arranged on the module housing 10, wherein the first light supplementing modules 20 comprise a first illuminant group 21, a focusing module 22 used for converging or focusing light rays of the first illuminant group 21, and a pattern piece 23 used for transmitting the converged or focused light rays and forming a specific projection pattern; the pattern piece 23 is arranged on the focal plane of the focusing assembly 22 or near the focal plane of the focusing assembly 22.

The car light of this embodiment is through setting up light filling module 100, and sets up pattern piece 23 in light filling module 100 to through the pattern on the pattern piece 23, make it can satisfy the demand that the consumer is to the car light multifunctionality, when the car light of this embodiment is installed on the vehicle, can assist the driving on the basis of ordinary far and near light illumination, help the driver to accurately make the driving judgement that is correlated with pattern piece 23, improve driving factor of safety. Specifically, when the vehicle lamp of the present embodiment is used, the light emitted by the first light-emitting body group 21 sequentially passes through the focusing assembly 22 and the pattern piece 23, and then exits to the vehicle lamp lens 600, and is projected by the vehicle lamp lens 600, since the pattern piece 23 is located at the focal plane of the focusing assembly 22; or the pattern piece 23 is disposed near the focal plane of the focusing assembly 22, so that when the light emitted by the first illuminant group 21 passes through the pattern piece 23, a bright light pattern corresponding to the pattern on the pattern piece 23 can be projected on the traffic lane, thereby assisting the driver in driving, helping the driver or the road pedestrian or the vehicle meeting vehicle accurately make driving judgment related to the pattern piece, and improving the driving safety coefficient.

Further, in the present embodiment, the first light emitter group 21 is a laser light emitter group, and the laser light emitter group 21 includes a first laser light emitter 211, a focusing lens 212 and a wavelength conversion member 213 sequentially disposed along the light emitting direction of the first laser light emitter 211, where the focusing lens 212 converges or focuses the light emitted by the first laser light emitter 211 onto the wavelength conversion member 213. The laser luminous body group is adopted, and the brightness of the emergent bright pattern is better.

In other embodiments, the first light emitter group may be an LED light emitter group including an LED chip and a phosphor layer coated on the LED chip. The brightness of the bright pattern emitted by the LED illuminant group is inferior to that of the laser illuminant group.

In this embodiment, the pattern piece 23 is an opaque piece, and a hollowed-out pattern is provided on the pattern piece 23. Therefore, when the light emitted by the first illuminant group 21 passes through the pattern piece 23, the light with a specific shape can be emitted to the road through the hollowed-out pattern to form a specific bright pattern. In other embodiments, a light transmissive sheet may be used as the pattern sheet and an opaque material may be applied to the relevant locations of the pattern sheet according to the desired light pattern.

The hollowed-out pattern in this embodiment is rectangular, and the light compensating module 100 is installed in the headlamps at two sides of the vehicle, as shown in fig. 3 and 4, the light compensating module 100 in this embodiment can respectively project a straight line at the left and right sides of the front of the vehicle when the vehicle is running, so as to realize the width indicating function, and enable a driver or other opposite vehicles to clearly know the running track of the vehicle during the running process. Particularly, for night narrow-road running, as the light supplementing light source can project a very bright straight line on two sides of a running route of the vehicle, a driver can conveniently and clearly see a running boundary line, judgment is accurately made, and running safety is guaranteed.

In other embodiments, the pattern piece 23 may be a pattern with other shapes, for example, the hollowed pattern may be a left arrow or a right arrow, so that a turning bright pattern may be projected, so that other drivers or pedestrians on the road can accurately know that the vehicle is about to turn.

The wavelength conversion member 213 of the present embodiment includes a phosphor sheet and a sheet sleeve for mounting the phosphor sheet.

The focusing assembly 22 of the present embodiment includes a lens that condenses or focuses the light of the first light emitter group 21 and a lens sleeve for fixing the lens.

The first lens portion 610 of the present embodiment is used solely for emitting the light beam of the supplementary light, and is not shared by the second lens portion 620 for emitting the light beams of the low beam module 300 and the high beam module 400, thereby achieving both light extraction efficiencies. More specifically, the first lens portion 610 and the second lens portion 620 are integrally formed.

Meanwhile, in this embodiment, the light incident surface of the lenslet is configured as a circular segment, that is, the light incident surface is not a standard circle, but is partially cut, and the cut edge is located at or coincides with the edge of the vehicle lamp lens. The advantages of this design are: if the light incident surface of the lenslet is standard circular, the position of the lenslet for entering the lamp lens needs to be shifted towards the center point of the lamp lens 600 under the condition of the same radius, which causes the lenslet to occupy a larger space of the lamp lens 600, thereby reducing the light emitting efficiency of the low beam module 300 and the high beam module 400. The light-emitting efficiency of the edge position of the lenslet is lower, and the edge of the lenslet is cut to form the lenslet with a circular-segment structure, so that the occupied area of the first lens portion 610 is reduced, the light-emitting efficiency of the light compensating module 100 is not greatly affected, and the light-emitting efficiencies of the low beam module 300, the high beam module 400 and the light compensating module 100 are simultaneously considered.

In order to improve the heat dissipation effect, the vehicle lamp of the present embodiment further includes a fan assembly 700 for dissipating heat from the heat dissipation substrate. In addition, the heat dissipating substrate 200 of the present embodiment is also provided with heat dissipating fins, which cooperate with the fan assembly 700 to improve heat dissipating efficiency.
