[0002] At present, light source packaging structures are widely used in mobile phone flashlights. Among them, the mainstream ceramic LEDs currently adopt a front-emitting packaging structure. Mainly, LED chips are eutectic on a ceramic substrate, phosphor is attached to the surface and around the LED chips, and then the redundant phosphor around the LED chips is removed, and an opaque adhesive is blocked around the LED chips, so that light is emitted in a single direction above the front of the LED chips.

[0003] Similar to traditional light source packaging structures such as ceramic LEDs, the light propagation direction of their light sources is all in a single direction, which is difficult to meet the requirement that the light source of the light source packaging structure propagates in multiple directions around, thereby making the irradiation area wider. Summary of the Invention

[0004] The purpose of the utility model is to provide a light source packaging structure, which can make the light source propagate in multiple directions around, increasing its irradiation area and irradiation effect.

[0005] The technical solution is as follows:

The light-emitting component is provided on the substrate. One end of the light-emitting component is fixedly provided on the substrate. The light-shielding component is also provided on the substrate. The light-shielding component corresponds to the substrate, and the light-shielding component is fixedly provided at the other end of the light-emitting component; a light-transmitting component is also provided between the substrate and the light-shielding component, and the light-transmitting component surrounds the outer edge of the light-emitting component.

[0007] A light source packaging structure, the light-emitting component is fixedly provided on the substrate, the light-emitting component can pass through the substrate and be connected to an external power supply to achieve the effect of emitting light, a light-shielding component is also provided on the substrate, the light-shielding component is fixed on the light-emitting component, thereby blocking the light of the light-emitting component from propagating to the top, a light-transmitting component is also provided between the substrate and the light-shielding component, the light-transmitting component surrounds the light-emitting component, and the light of the light-emitting component is propagated to the lateral sides around the light-emitting component through the light-transmitting component, increasing the irradiation area of the light-emitting component, and the light-emitting component can also be set to propagate in different angles around in an orderly manner, thereby increasing the irradiation effect of the packaging structure.

[0008] In one embodiment, the light-shielding component includes a first reflecting surface, and the first reflecting surface corresponds to the light-emitting component and the light-transmitting component.

[0009] On one side of the light-shielding member close to the light-emitting member and the light-transmitting member, a first reflection surface is provided. Through the first reflection surface, the light propagated upward by the light-emitting member is reflected back into the light-transmitting member for reflection, and the light reflected upward in the light-transmitting member is reflected back into the light-transmitting member, improving the concentration of light propagation in the direction of the light-transmitting member and enhancing the light source utilization rate of the light-emitting member.

[0010] In one embodiment, the substrate includes a second reflection surface corresponding to the first reflection surface.

[0011] The substrate is provided with a second reflection surface corresponding to the first reflection surface. Through the second reflection surface, the light reflected downward by the light source of the light-emitting member is reflected back into the light-transmitting member, and the light reflected downward in the light-transmitting member is reflected back into the light-transmitting member, and cooperates with the first reflection surface to form a reflection channel, guiding the light of the light-emitting member to propagate in all directions to the greatest extent, greatly improving the transmission effect of the light-emitting member.

[0012] In one embodiment, the substrate material is set as ceramic; or the substrate material is set as a mixture of ceramic and metal.

[0013] Since the light-emitting member has a relatively high working temperature after long-term use, when the substrate material is set as ceramic, the high-temperature resistance of the substrate can be improved; when the substrate material is set as a mixture of ceramic and metal, the high-temperature resistance of the substrate can be improved and it has good thermal conductivity, so that the packaging structure has good heat dissipation ability, improving its service life and stability.

[0014] In one embodiment, the light-emitting member is a light-emitting diode, and the light-emitting diode is eutectic on the substrate.

[0015] The light-emitting member is a light-emitting diode, and the light-emitting diode is eutectic on the substrate, so that the light-emitting member and the substrate are better connected together, improving the stability of the packaging structure.

[0016] In one embodiment, the light-emitting member is provided with a plurality of LED lamp beads, the plurality of LED lamp beads are connected together, and the plurality of LED lamp beads are circumferentially distributed on the substrate.

[0019] The different light transmittance rates of the first light transmissive member and the second light transmissive member can obtain a wider range of light transmittance by combining two different light transmissive members. In particular, different light transmissive members can have different light transmission effects and filter different lights according to specific requirements.

[0020] In one embodiment, the first light transmissive member is a phosphor and the second light transmissive member is a transparent glue, and the first light transmissive member and the second light transmissive member are mixed to form the light transmissive member.

[0021] The first light transmissive member is a phosphor and the second light transmissive member is a transparent glue. After the phosphor and the transparent glue are mixed to form a solid-liquid mixture and then solidified, the light transmissive member is formed. Thereby, the first light transmissive member and the second light transmissive member are more uniformly fused. The phosphor is located at different positions in the transparent glue, which can form different reflection effects, increase the transmission effect of the light transmissive member, and also has a better sealing effect, further ensuring the airtightness of the packaging structure and preventing the internal light-emitting component from being penetrated by water vapor, which affects the use efficiency of the light-emitting component.

[0022] In one embodiment, the first light transmissive member surrounds the light-emitting component, and the second light transmissive member surrounds the first light transmissive member.

[0023] The first light transmissive member surrounds the light-emitting component, and the second light transmissive member surrounds the first light transmissive member. The first light transmissive member is closer to the light-emitting component than the second light transmissive member. Since the light-emitting component has a relatively high temperature after long-term use, by setting the first light transmissive member, such as a phosphor, which is more heat-resistant, and there are gaps between the phosphors, which is beneficial to improving heat dissipation, thereby improving the stability and service life of the packaging structure, ensuring the use effect of the light transmissive member. Moreover, the second light transmissive member can play a role in sealing and isolating between the substrate and the outer edge of the light-shielding member, preventing water vapor from penetrating into the first light transmissive member and the light-emitting component, and ensuring the service life and stability of the light transmission effect of the packaging structure.

[0035] Embodiment 1:

[0036] As Figure 1 、 Figure 2 shown in the light source packaging structure, including a substrate 10, a light-emitting component 20, a light-shielding component 30, and a translucent component 40. The light-emitting component 20 is provided on the substrate 10. One end of the light-emitting component 20 is fixedly arranged on the substrate 10. The light-emitting component 20 can pass through the substrate 10 and be connected to an external power source to achieve the effect of emitting light. The light-shielding component 30 is also provided on the substrate 10. The light-shielding component 30 corresponds to the substrate 10. The light-shielding component 30 is fixedly arranged at the other end of the light-emitting component 20, thereby blocking the light of the light-emitting component 20 from propagating to the top; the translucent component 40 is also provided between the substrate 10 and the light-shielding component 30. The translucent component 40 surrounds the outer edge of the light-emitting component 20. The light of the light-emitting component 20 is propagated to the lateral surroundings of the light-emitting component 20 through the translucent component 40, increasing the irradiation area of the light-emitting component 20, and the light-emitting component 20 can also be set to propagate in different directions around in an orderly manner, thereby increasing the irradiation effect of the packaging structure.

[0037] As Figure 2 shown, the light-shielding member 30, the substrate 10, and the light-emitting member 20 are further described as follows:

[0038] The light-shielding member 30 includes a first reflecting surface 31, which corresponds to the light-emitting member 20 and the light-transmitting member 40. Through the first reflecting surface 31, the light propagated upward by the light-emitting member 20 is reflected back into the light-transmitting member 40 for reflection, and the light reflected upward in the light-transmitting member 40 is also reflected back into the light-transmitting member 40, improving the concentration of the light propagating in the direction of the light-transmitting member 40 and enhancing the light source utilization rate of the light-emitting member 20; the substrate 10 includes a second reflecting surface 11, which corresponds to the first reflecting surface 31. Through the second reflecting surface 11, the light reflected downward by the light source of the light-emitting member 20 is reflected back into the light-transmitting member 40, and the light reflected downward in the light-transmitting member 40 is also reflected back into the light-transmitting member 40, and cooperates with the first reflecting surface 31 to form a reflection channel, guiding the light of the light-emitting member 20 to propagate in all directions to the greatest extent and greatly improving the transmission effect of the light-emitting member 20.

[0039] Since the light-emitting member 20 has a relatively high operating temperature after long-term use, when the material of the substrate 10 is set to ceramic, the high-temperature resistance of the substrate 10 can be improved; when the material of the substrate 10 is set to a ceramic-metal mixture, the high-temperature resistance of the substrate 10 can be improved and it has good thermal conductivity, so that the packaging structure has good heat dissipation ability and improves its service life and stability.

[0040] The light-emitting member 20 is a light-emitting diode. Preferably, the light-emitting member 20 can be an LED lamp bead. The LED lamp bead can improve the irradiation power of the light source and has a better irradiation effect. The light-emitting diode is eutectic on the substrate 10, so that the light-emitting member 20 and the substrate 10 are better connected together, improving the stability of the packaging structure; the light-emitting member 20 can also be provided with a plurality of LED lamp beads. The plurality of LED lamp beads are tightly connected together and are circumferentially distributed on the substrate 10, so that the flashing times of different LED lamp beads can be set differently, and thus the light is propagated in different set angles respectively, improving the personalized customization function of the light source propagation and increasing the irradiation effect of the light of the light-emitting member 20 propagating in all directions.

[0041] As Figure 2 shown, the light-transmitting member 40 is further described:

[0042] The light-transmitting member 40 may be a phosphor. After fixing the light-emitting member 20 to the substrate 10 by eutectic technology, the phosphor is coated on the surface and around the light-emitting member 20. Then, after removing the phosphor above the light-emitting member 20 by grinding, the light-shielding member 30 is fixed above the light-emitting member 20 and the phosphor.

[0043] The light-transmitting member 40 may further include a first light-transmitting member 41 and a second light-transmitting member 42. The first light-transmitting member 41 and the second light-transmitting member 42 have different light transmittances. By combining two different light-transmitting members 40, a wider range of light transmittances can be obtained. In particular, different light-transmitting members 40 may have different light-transmitting effects to filter different lights according to specific requirements. Preferably, the first light-transmitting member 41 is a phosphor, and the second light-transmitting member 42 is a transparent glue. After the phosphor and the transparent glue are mixed into a solid-liquid mixture and then solidified, the light-transmitting member 40 is formed, so that the first light-transmitting member 41 and the second light-transmitting member 42 are more uniformly fused. The phosphor is located at different positions in the transparent glue, which can form different reflection effects, increase the transmission effect of the light-transmitting member 40, and also has a better sealing effect, further ensuring the airtightness of the packaging structure and preventing the internal light-emitting member 20 from being penetrated by water vapor, which affects the use efficiency of the light-emitting member 20.

[0044] Embodiment 2:

[0045] As Figure 3 shown, the difference from Embodiment 1 is that the first light-transmitting member 41 surrounds the light-emitting member 20, the second light-transmitting member 42 surrounds the first light-transmitting member 41, and the first light-transmitting member 41 is closer to the light-emitting member 20 than the second light-transmitting member 42. Since the light-emitting member 20 has a relatively high temperature after long-term use, by providing the first light-transmitting member 41 that is more heat-resistant, such as a phosphor, and there are gaps between the phosphors, which is beneficial to improving heat dissipation, thereby improving the stability and service life of the packaging structure, ensuring the use effect of the light-transmitting member 40, and the second light-transmitting member 42 can play a role in sealing and isolating between the substrate 10 and the outer edge of the light-shielding member 30, preventing water vapor from penetrating into the first light-transmitting member 41 and the light-emitting member 20, and ensuring the service life and stability of the light-transmitting effect of the packaging structure.

Any substitution and improvement made without violating the concept of the present utility model fall within the protection scope of the present utility model.
