However, as the light emitting surface of the LED light source is larger, the emitting angle is larger, the optical power density is lower, and the illumination light of the LED array after light distribution by the optical element cannot meet the requirement of high central brightness required by the illumination of the automobile headlight.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The brightness of the automobile lamp and the distribution of the automobile illumination light influence the safe driving of the automobile, and the existing LED light source automobile lamp generally adopts an LED array to realize a larger illumination range and a higher illumination flux because the maximum illumination flux of a single LED chip is not more than 300 lumens, so that the LED light source automobile lamp has the following two problems that on one hand, the central illumination of illumination light cannot meet the standard of an automobile lamp headlight after the light distribution treatment of a light collecting system due to the smaller light power density of the LED light source; on the other hand, the LED array is used as a light source, and the light emergent surface is larger, so that the volume of the light collecting system is larger, and the vehicle lamp is larger. In order to solve the above technical problems, the present application provides the following embodiments.
The embodiments of the present application will be described in detail below with reference to the accompanying drawings and the embodiments.
Example 1
Referring to fig. 1, the present embodiment provides an illumination light source system, which includes a first light source 110 and a second light source module 120; wherein the first light source comprises at least two LED light sources 111, emitting first light; the second light source module 120 includes a laser light source 121 and a collecting lens 122. The laser light source 121 emits the second light, and the collecting lens 122 collects and condenses the second light to the first convergence point. Further, the first convergence point intersects the light-emitting surface of the LED light source 111; the first convergence point is located between at least two LED light sources 111; the divergence angle of the second light at the first convergence point is smaller than the divergence angle of the first light on the light-emitting surface. The first light and the second light are emitted in the same direction on the plane where the light emitting surface of the LED light source 111 is located, and together form the output light of the illumination light source system.
The first light source 110 includes at least two LED light sources 111 for emitting first light, wherein the first light is lambertian light, and the light emitting angle is 180 degrees. In a specific embodiment, the light emitting surface of each LED light source is 1X 1mm 2 。
The second light source module 120 includes a laser light source 121 and a collecting lens 122. The laser light source 121 is a semiconductor laser for emitting the second light, the brightness and the optical power density of the second light are both higher, the second light is collected and converged by the collecting lens 122, so that the second light is converged at the first convergence point, the first convergence point intersects with the light emitting surface of the LED light source 111, and the inventor finds that when the distance from the center of the first convergence point to the light emitting surface of the LED light source is less than 0.03mm through a great number of repeated experiments, the center brightness and the optical distribution of the illumination light emitted by the illumination light source system have no or little influence, and all the ideal hot areas of the illumination light of the automotive headlight can be formed. The size of the first convergence point and/or the divergence angle of the second light at the first convergence point in the illumination light source system are both adjustable, and the size of the first convergence point and/or the divergence angle of the second light at the first convergence point can be changed by changing the curvature of the convex surface of the collecting lens 122 or changing the distance between the collecting lens 122 and the laser light source 121. The central intensity of the output illumination light can be varied by adjusting the size of the first convergence point diameter and/or the size of the divergence angle at the second light convergence point. In this embodiment, the divergence angle of the second light at the first convergence point is smaller than the divergence angle of the first light, and further, the divergence angle of the second light at the first convergence point is at least smaller than 80% of the divergence angle of the first light at the light emitting surface of the LED light source.
Referring to tables 1 and 2, the present inventors found, through experiments and simulations, that the luminous flux and the central illuminance of the light emitted from the illumination light source are changed when the diameter of the first convergence point is changed in the range of 0.5mm to 1.0mm, and the luminous flux and the central illuminance of the light emitted from the illumination light source are changed when the divergence angle of the second light at the first convergence point is changed in the range of 60 degrees to 160 degrees. The smaller the diameter of the first convergence point is, the larger the central illuminance of the output light of the illumination light source system is; the smaller the divergence angle of the second light at the first convergence point, the greater the central illuminance of the illumination light outputted by the illumination light source system.

However, the substrate 160 and the heat sink 170 are not necessary in the present application, in some cases, a single LED bead may be directly packaged on the heat sink 170, and the heat sink 170 is used to dissipate heat from the LED bead; when the output current of the LED light source 111 is small, the heat generation of the LED light source 111 is small, and the heat sink 170 may not be required. In this embodiment, the LED light sources 111 are preferably disposed on the substrate 160, the substrate 160 is a PCB board made of copper and includes a through hole, and the LED light sources 111 are arranged in a straight line on both sides of the through hole or around the through hole; the substrate 160 is disposed on the heat sink 170, and the substrate 160 is connected to the heat sink 170 by soldering or bonding. The heat sink 170 includes a through hole, and the position of the through hole of the heat sink 170 coincides with the position of the through hole of the substrate 160, and the heat sink 170 dissipates the heat generated by the LED light source 111.

The difference between this embodiment and embodiment 1 is that the heat spreader 180 includes a groove structure, the position of the groove structure of the heat spreader 180 coincides with the position of the through hole of the substrate 160, and the heat spreader 180 can radiate the LED light source 111 and the laser light source 121 at the same time, so that the service life of the illumination light source system can be further prolonged.

The light conversion layer 230 includes a matrix, which may be silica gel, glass, or ceramic, and a light conversion center and/or a light scattering center; the light conversion center may comprise yellow phosphor or quantum dots, or green phosphor or quantum dots and red phosphor or quantum dots; the light scattering center may be titanium oxide particles, silicon oxide particles, aluminum oxide particles, or the like, and the refractive index of the particles is different from that of the matrix. The light conversion layer 230 may absorb the laser light and emit third light, which is different from the wavelength or light distribution of the laser light. Since the brightness and the optical power density of the second light emitted from the laser light source 221 are both large, the brightness of the third light emitted from the light conversion layer 230 is also large. The second light emitted by the laser light source 221 is converted by the light conversion layer to emit third light, the peak wavelength or light distribution of the third light is different from that of the second light, and the third light is collected and converged by the collecting lens 122, so that the third light is converged at a first convergence point which is intersected with the light emitting surface of the LED light source 211, and the distance from the center of the first convergence point to the light emitting surface of the LED light source 211 is less than 0.03mm; the first convergence point is located between at least two LED light sources.

Referring to fig. 8, since the laser light source 321 has higher brightness and smaller etendue, the outgoing light is irradiated farther than the outgoing light of the LED light source 311.
In this embodiment, the illumination light center output by the illumination light source system has a high illuminance, and the illumination light center forms a hot zone with ideal high brightness.
Fig. 5 shows a modified embodiment of the present embodiment, where the illumination light source system includes a first light source 310, a second light source module 320 and a lens 340, and the difference between the present embodiment and embodiment 3 is that the light collecting system is the lens 340, and the description of other constituent elements is referred to in embodiment 3.
