[0029] A backlight source is a light source used to provide backlight illumination, and is usually used in devices such as liquid crystal displays (LCDs). It is located on the back of the liquid crystal display screen and emits light forward, so that the images on the display screen can be normally displayed. The backlight source mainly emits light forward and needs to have a certain directivity. The backlight source needs to meet requirements such as uniform light source color and high brightness. The backlight source of the existing packaging structure only emits light forward. Please refer to Figure 2 , the light-emitting element 2 is fixed on the substrate 1, the side of the light-emitting element 2 is blocked, only the light emitted from the front of the light-emitting element 2 is effective, and the utilization rate of the light emitted from the side of the light-emitting element is relatively low.

[0030] Therefore, in the embodiments of this application, a light source structure, a light source system, and a carrier system are provided to solve or partially solve the above problems.

[0031] Please refer to Figure 1 , which shows a schematic structural diagram of a light source structure provided by an embodiment of this application. The light source structure includes: a substrate 1, a light-emitting element 2, a first dam glue layer 3, and a second dam glue layer 4.

[0032] The light-emitting element 2 has a soldering surface 21 and a first light-emitting surface 22 which are arranged opposite to each other. The first light-emitting surface 22 faces the light-emitting direction of the light-emitting element 2. The side surface between the soldering surface 21 and the first light-emitting surface 22 is a second light-emitting surface 23. The soldering surface 22 is fixedly connected to the substrate 1.

[0033] The first dam glue layer 3 is a light-transmitting layer, which is arranged around the second light-emitting surface 23. The second dam glue layer 4 is a light-reflecting layer, which is arranged around the first dam glue layer 3. The light emitted from the second light-emitting surface 23 passes through the first dam glue layer 3 and is reflected by the second dam glue layer 4, and then is emitted along the light-emitting direction of the light-emitting element 2.

[0034] It should be noted that circuits or vias are etched on the substrate. The light-emitting element is fixed on the substrate and can be connected to an external circuit through the substrate. When the circuit of the light-emitting element is connected, the light-emitting element can emit light. The light-emitting element can be an LED lamp, an incandescent lamp, a halogen lamp, a fluorescent lamp or a laser diode, and no specific limitation is made here.

[0035] The soldering surface of the light-emitting element is fixed on the substrate. Both the first light-emitting surface and the second light-emitting surface of the light-emitting element can emit light. The first light-emitting surface faces the light-emitting direction of the light-emitting element, that is, the light emitted along the orientation of the first light-emitting surface is the target light.

[0036] It should be noted that the first dam glue layer is made of a transparent material, and light can pass through the first dam glue layer. That is to say, the light emitted from the second light-emitting surface can irradiate inside the first dam glue layer. The higher the refractive index of the first dam glue layer, the greater the probability that the light emitted from the second light-emitting surface is redirected to be emitted along the light-emitting direction of the light-emitting element.

[0037] Since the light emitted from the second light-emitting surface changes direction after refraction when propagating to the first dam glue layer, and the direction of the light is changed again by the reflection of the second dam glue layer on the light, most of the light emitted from the second light-emitting surface can pass through the first dam glue layer and be emitted along the light-emitting direction of the light-emitting element.

[0038] An exemplary one, please refer to Figure 1 , in which the straight line with an arrow represents a partial light path. When the light-emitting element 2 is powered on, the first light-emitting surface 22 and the second light-emitting surface 23 emit light. The light emitted from the second light-emitting surface 23 can change the propagation direction of the light through the first dam glue layer 3, and then the light is reflected by the second dam glue layer 4 and is emitted from the first dam glue layer 3 along the light-emitting direction of the light-emitting element, realizing the guiding of the light on the side to be emitted from the front, which not only enlarges the light-emitting area of the light-emitting element 2 but also improves the light-emitting efficiency of the light-emitting element 2.

[0039] In this application, the first dam glue layer is arranged around the second light-emitting surface, and the second dam glue layer is arranged around the first dam glue layer. The light emitted by the second light-emitting surface changes direction after passing through the first dam glue layer and the second dam glue layer, and is emitted from the light-emitting direction of the light-emitting element. On the one hand, the utilization rate of the light emitted from the side of the light-emitting element is improved, and the overall utilization rate of the light-emitting element is improved. On the other hand, the light-emitting area in the light-emitting direction is increased by the first dam glue layer, thereby increasing the brightness of the light source. Without changing the light-emitting element and power, the light-emitting efficiency is effectively improved.

[0040] Preferably, the first dam glue layer is a transparent silica gel dam layer.

[0041] Specifically, the first dam glue layer can be at least one of a one-component high-temperature curing phenyl silicone resin, a two-component high-temperature curing phenyl silicone resin, and a multi-component high-temperature curing phenyl silicone resin.

[0042] Preferably, the second dam glue layer is a white glue dam layer.

[0043] Specifically, the second dam glue layer can be at least one of a two-component titanium dioxide silica gel and a three-component titanium dioxide silica gel.

[0044] Further, please refer to Figure 7 , on the reference surface 31, on the first light-emitting surface 22, and between the first dam glue layer 3 and the second dam glue layer 4, a wavelength conversion layer 5 is formed. The wavelength conversion layer 5 is used to absorb the light emitted by the first light-emitting surface 22 and the second light-emitting surface 23 and perform wavelength conversion. The reference surface 31 is the surface of the first dam glue layer 3, and the reference surface 31 faces the light-emitting direction of the light-emitting element 2 and is not covered by the second dam glue layer 4.

[0045] It should be noted that when the color of the light emitted by the light-emitting element is the same as the target color, the light-emitting element can be directly used. When the color of the light emitted by the light-emitting element is different from the target color, the color of the light needs to be changed. For example, if the light-emitting element emits blue light and white light is needed, the color of the light can be changed through the wavelength conversion layer.

[0046] The wavelength conversion layer includes a fluorescent material. The fluorescent material can absorb light of a specific wavelength and then re-emit it as light of a different wavelength, that is, the color of the light can be changed through the wavelength conversion layer, and the color of the light emitted by the light-emitting element can be changed to the target color.

[0047] Preferably, the wavelength conversion layer is a phosphor layer or a quantum dot layer.

[0048] Specifically, the phosphor layer is prepared by mixing a certain proportion of phosphors, silica gel, and diluent. The emission color of the phosphor depends on its chemical composition and structure. Different colors of light can be produced by adjusting the composition and properties of the phosphor. The composition of the phosphor is not limited here and is determined according to actual applications.

[0049] Specifically, the quantum dot layer is prepared by mixing a certain proportion of quantum dots, silica gel, and diluent. Quantum dots are semiconductor materials at the nanoscale, and the emission color of quantum dots can be precisely controlled by changing the particle size. The smaller the size, the shorter the wavelength of the emitted light, and vice versa. Therefore, quantum dots can cover a wider spectral range.

[0050] Further, please refer to Figure 7 , the encapsulation surface of the substrate 1 is bonded to the second dam adhesive layer 4 through the wavelength conversion layer 5, and the encapsulation surface is the surface connected to the welding surface.

[0051] It should be noted that during the process of processing the light source structure, the light-emitting element is first fixed on the substrate, and then the first dam adhesive layer is bonded to the second light-emitting surface, and then the wavelength conversion layer is installed. Generally, the wavelength conversion layer is installed by spraying. Precise positioning of the first light-emitting surface and the reference surface is costly. Therefore, the wavelength conversion layer can be sprayed on the entire surface to improve the installation efficiency of the wavelength conversion layer.

[0052] An exemplary light-emitting element is a cube, the first light-emitting surface is rectangular, and there are 4 second light-emitting surfaces. The first dam adhesive layer is bonded to all 4 second light-emitting surfaces, and the second dam adhesive layer is a reflective layer that surrounds the first dam adhesive layer. In this way, more of the light emitted from the second light-emitting surface can be directed out in the light-emitting direction of the light-emitting element, and the effective light-emitting area of the light-emitting element is also increased, improving the light-emitting efficiency without changing the light-emitting element and power.

[0053] An exemplary light-emitting element is a cylinder, the first light-emitting surface is circular, the second light-emitting surface is the side surface of the cylinder, the first dam adhesive layer surrounds the second light-emitting surface, and the second dam adhesive layer surrounds the first dam adhesive layer, so that part of the light emitted from the second light-emitting surface can be redirected in the light-emitting direction of the light-emitting element.

[0054] It should be noted that if the surface of the first dam adhesive layer is not flat, it may cause uneven spraying of the wavelength conversion layer bonded to the first dam adhesive layer, and unevenness of the wavelength conversion layer easily leads to uneven light color, failing to meet the requirement of uniform light source color.

[0055] Therefore, further, the surface of the first dam adhesive layer is flat.

[0056] Further, the reference plane is on the same plane as the first light-emitting surface.

[0057] Preferably, the length of the first dam glue layer extending along the plane where the first light-emitting surface is located is 0.1 times the length of the first light-emitting surface.

[0058] Further, the first dam glue layer has a first end portion and a second end portion which are oppositely arranged, the distance from the first end portion to the substrate is greater than the distance from the second end portion to the substrate; the area of the projection of the first end portion on the plane where the first light-emitting surface is located is smaller than the area of the projection of the second end portion on the plane where the first light-emitting surface is located.

[0059] Further, the first dam glue layer has a first end portion and a second end portion which are oppositely arranged, the distance from the first end portion to the substrate is greater than the distance from the second end portion to the substrate; the area of the projection of the first end portion on the plane where the first light-emitting surface is located is equal to the area of the projection of the second end portion on the plane where the first light-emitting surface is located.

[0060] It should be noted that the shape of the first dam glue layer can be determined according to actual needs, and the purpose is to direct the light emitted by the second light-emitting surface to the light-emitting direction of the light-emitting element as much as possible.

[0061] Exemplarily, the manufacturing process of the light source structure of the present application includes: die bonding, transparent silicone dam, grinding, atomizing and spraying a wavelength conversion layer, and white glue filling.

[0062] Specifically, die bonding: For the structure obtained after die bonding, please refer to Figure 3 , fix the light-emitting element 2 on the substrate 1 with flux or solder paste, and complete the welding through a vacuum eutectic furnace. There may be flux residues during the welding process, and these residual yellow transparent fluxes may affect the light-emitting effect of the light-emitting element 2. Therefore, an ultrasonic cleaning device is used to heat the residual flux with an ethylene glycol ether solvent to 70 °C for cleaning for 5-7 minutes, and then rinse with distilled water. After the rinsing is completed, a dehumidifying and drying treatment at 150 °C for 1 hour is carried out.

[0063] Transparent silicone dam: For the structure obtained after damming, please refer to Figure 4, a first dam glue layer 3 with a high refractive index is selected. Its phenyl-based refractive index is 1.54 - 1.59, the light transmittance is as high as 90% @ 400nm / 2.0mm or more, and the mixing viscosity is in the range of 5000 - 8000 mPa·s. During the dam process, an electromagnetic valve dam machine is used for program debugging, and the dam is carried out around the light-emitting element 2 in the form of drawing lines or dots. After damming, a vacuum automatic temperature-rising heating oven is used. First, vacuum is pumped in the oven, and then heating and baking are started. The baking conditions are divided into three stages: 60°C / 30 minutes, 80°C / 1 hour, 150°C / 3 hours to ensure the full curing of the first dam glue layer 3.

[0064] Grinding: After damming, please refer to Figure 4 , the surfaces of the first dam glue layer 3 and the light-emitting element 2 may be slightly uneven, which will affect the atomization spraying quality of the subsequent wavelength conversion layer. Therefore, a high-precision grinding machine is used to grind and polish the surfaces of the first dam glue layer 3 and the light-emitting element 2. The structure obtained after grinding is shown in Figure 5 . After grinding, a high-pressure cleaning machine is used to clean at a ratio of pure water to silicone surfactant of 10:1. After cleaning, the sample is placed in a dehumidifying oven and dried at 150°C for 1 hour to ensure the surface is dry.

[0065] Atomization spraying of the wavelength conversion layer: After grinding, the wavelength conversion layer is atomization sprayed. A certain proportion of phosphor, silicone, and diluent are mixed to prepare the wavelength conversion layer 5. The spraying frequency of the wavelength conversion layer 5 is controlled by an electromagnetic valve to ensure uniform spraying on the surfaces of the ceramic substrate 1, the first dam glue layer 3, and the light-emitting element 2 to form a complete wrap. The structure after atomization spraying of the wavelength conversion layer is shown in Figure 6 . After confirming that the optoelectronic parameters meet the requirements, the sample is placed in a vacuum automatic temperature-rising heating oven. First, vacuum is pumped, and then baking is carried out. The baking conditions are divided into three stages: 60°C / 30 minutes, 80°C / 1 hour, 150°C / 3 hours. The whole process is precisely controlled to ensure that the spraying quality and parameters meet the standards.

[0066] White glue filling: After atomization spraying, the second dam glue layer 4 is used for white glue filling. An electromagnetic valve white glue filling device is used to debug the program to the line drawing mode. The moving speed of the device in the XY-axis direction is set to 30 - 60 mm / s, the supply glue air pressure parameter range is 0.03 to 0.35 MPa, and the preheating temperature before white glue filling needs to be set to 60°C ± 5°C. The valve body control uses a glue valve that sprays with a pulse signal, spraying once per pulse, and a piezoelectric spray valve is equipped to achieve continuous spraying. The structure after white glue filling is shown in Figure 7 . After white glue filling is completed, the glue is cured and baked in a segmented manner. The first-stage temperature range is set to 80°C / 1H, and the second-stage temperature range is set to 150°C / 2H for shaping and curing. The oven air needs to be pumped out before heating up.

[0067] The present application also provides a light source system, which includes: a housing and the aforementioned light source structure; the housing is used to encapsulate the light source structure, the housing has a first hole and a second hole, the first hole serves as an access port for an electric wire, and the electric wire is used to connect the substrate, and the second hole serves as a light outlet of the light source structure.

[0068] The present application also provides a vehicle system, which includes: a main body and the aforementioned light source system; the main body has a mounting position, and the mounting position is used to mount at least one of the light source systems.

[0069] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
