Description

Technical Field

[0001] The present application relates to the technical field of light source equipment, and in particular to a light source device. Background Art

[0002] At present, in the light source array, multiple light guides are arranged one by one with multiple light emitting chips, and the light emitted by the light emitting chips can be emitted after being transmitted through the light guides. Liquid silicone rubber (LSR) has become the material for making light guides because of its excellent optical transparency, blue light resistance, and easy demolding. However, the disadvantage of liquid silicone rubber is that it is soft after curing, easy to deform, and its thermal expansion coefficient is relatively large. This increases the probability of deformation due to thermal expansion when working at high temperatures. The single cone rod structure is relatively slender and more prone to deformation.

[0003] When the light source array is working, a large amount of heat is emitted from the surface of the light-emitting chip. The heat will affect the cone rod adjacent to the light-emitting chip, and the cone rod will be deformed and elongated due to the high temperature. The high temperature will make the lower surface of the cone rod basically flush with the surface of its fixed structure. After being heated, the cone rod will continue to elongate and abut against the surface of the light-emitting chip, affecting the optical coordination between the cone rod and the light-emitting chip. The light cannot be fully coupled into the cone rod, resulting in light leakage. Utility Model Content

[0024] Example

[0025] The present application embodiment provides a light source device 1, see Figure 1 as well as Figure 2 The light source device 1 may include a light source array 100, a light guide assembly 200 and an isolating member 300. The light source array 100 includes a substrate 110 and a plurality of light emitting chips 120, and the light emitting chips 120 may be light emitting diodes (LEDs). The plurality of light emitting chips 120 are arranged in an array on the surface of the substrate 110. The light guide assembly 200 includes a bracket 210 and a plurality of cone rods 220. The bracket 210 and the substrate 110 are connected and fixed to each other so that the plurality of light emitting chips 120 can be arranged one by one with the plurality of cone rods 220, and the light emitted by each light emitting chip 120 can be obtained and coupled into the corresponding cone rod 220. The light emitting chip 120 generates heat when working, and the cone rod 220 softens due to the heat. The isolating member 300 is arranged between the light emitting chip 120 and the cone rod 220 opposite to each other, and the end of the softened cone rod 220 close to the light emitting chip 120 abuts against the surface of the isolating member 300. The spacer 300 can prevent the deformed cone rod 220 from contacting the light emitting chip 120 , thereby ensuring the optical coordination between the light emitting chip 120 and the cone rod 220 , and thereby preventing the light source device 1 from leaking blue light.

[0026] Specifically, the material of the cone rod 220 is solidified liquid silicone rubber (LSR), so that the cone rod 220 has good optical transparency and allows the light beam to pass through with minimal distortion. At the same time, the cone rod 220 also has good design flexibility and can be molded into complex shapes and features, and can still be deformed and elastic after solidification to facilitate demolding. In addition, the cone rod 220 also has good light resistance and no yellowing, so it has a long service life and high reliability. Moreover, the cone rod 220 has good temperature resistance and can withstand a wide range of temperatures, and will not lose its performance even in extremely cold and hot environments.

[0027] Please continue reading Figure 1 as well as Figure 2 The bracket 210 can be configured as a metal bracket, such as stainless steel, etc. The metal bracket has good thermal conductivity. The heat emitted by the light source array 100 during operation is transferred to the cone rod 220, and the cone rod 220 can also dissipate heat through the metal bracket 210 to reduce the working temperature of the cone rod 220. Specifically, the bracket 210 has a plurality of fixing holes 211, and the shapes and sizes of the fixing holes 211 and the cone rod 220 are matched with each other. The plurality of cone rods 220 are arranged in a one-to-one correspondence in the plurality of fixing holes 211, and each cone rod 220 includes a first end 221 and a second end 222 opposite to each other, and the fixing hole 211 limits the second end 222 in a direction perpendicular to the length direction. The cross-sectional area of ​​the cone rod 220 gradually decreases in the direction from the second end 222 to the first end 221. It can be understood that the limiting hole 430 is also cone-shaped as a whole. After the cone rod 220 passes through the fixing hole 211, the inner wall surface surrounding the fixing hole 211 can provide auxiliary support for the cone rod 220 in the direction from the first end 221 to the second end 222.

[0028] Please continue reading Figure 2 , the second ends 222 of the plurality of cone rods 220 may also be provided with a glass carrier 400, and the glass carrier 400 is provided on the side of the bracket 210 away from the light source array 100. The glass carrier 400 abuts against the second ends 222 of the cone rods 220, and the glass carrier 400 is connected to the bracket 210, so that the glass carrier 400 can limit the cone rods 220 in the fixing holes 211 of the bracket 210. Exemplarily, the glass carrier 400 may be hard glass, so that it has a high hardness and can be used as a carrier for connecting the plurality of cone rods 220, so as to facilitate the installation of the plurality of cone rods 220 on the glass carrier 400. In addition, since the glass carrier 400 is hard glass, it can have a high manufacturing accuracy and can be used as a high-precision positioning structure to cooperate with the first limiting portion 320 for limiting. The glass carrier 400 may be a thin-film coated glass coated with metal, alloy or metal compound to meet the need for light beam transmission.

[0029] In one embodiment, a plurality of cone rods 220 are connected to the glass carrier 400 and distributed in an array, and the plurality of cone rods 220 are connected to each other through the glass carrier 400. Furthermore, by spin-coating optical adhesive on the surface of the glass carrier 400 facing the substrate 110, the array formed by the plurality of cone rods 220 through mold molding can be bonded to the glass carrier 400 to form a whole with the glass carrier 400.

[0030] The plurality of cone rods 220 are arranged in one-to-one correspondence with the plurality of light emitting chips 120, and the first end 221 is adjacent to the light emitting chip 120, that is, each light emitting chip 120 is provided with a corresponding cone rod 220. The first end 221 of the cone rod 220 is adjacent to the light emitting chip 120, and the emitted light of the light emitting chip 120 can be coupled into the cone rod 220 through the first end 221. Furthermore, the positioning relationship between the bracket 210 and the substrate 110 can prevent the first end 221 from being offset or displaced relative to the light emitting chip 120, ensure that the first end 221 and the light emitting chip 120 are aligned, and ensure that the light emitted by the light emitting chip 120 is efficiently coupled into the cone rod 220.

[0031] Furthermore, the light source array 100 may further include a heat sink 500, which is disposed on the side of the substrate 110 that is away from the glass carrier 400. In addition, the heat sink 500 is closely attached to the side of the substrate 110 that is away from the glass carrier 400 and has a large contact area with the substrate 110, so that the heat generated by the plurality of light-emitting chips 120 can be conducted to the heat sink 500 via the substrate 110, and then conducted out via the heat sink 500 to achieve the effect of heat dissipation and temperature reduction.

[0032] In this example, see Figure 2 The isolating member 300 may be a metal structural member to provide stable support, avoid thermal deformation, and always ensure the spacing between the cone rod 220 and the light-emitting chip 120. At the same time, the isolating member 300 may have a high manufacturing accuracy and may provide a high-precision limiting structure. The isolating member 300 is provided with a plurality of light-transmitting holes 310. The isolating member 300 is pressed against the light source array 100 by the first end 221 and is in direct contact with the light-emitting chip 120. The isolating member 300 includes a first surface and a second surface relative to each other. The first surface abuts against the surface of the light-emitting chip 120 close to the first end 221, and the second surface abuts against the first end 221. The plurality of light-transmitting holes 310 correspond to the plurality of light-emitting chips 120, and the light-emitting chip 120 is provided with at least one light-transmitting hole 310 correspondingly, so that the light of the light-emitting chip 120 can be transmitted through the light-transmitting hole 310. Furthermore, the light-transmitting hole 310 is located in the projection of the cone rod 220 toward the light-emitting chip 120 , so that the emitted light of the light-emitting chip 120 can be emitted into the cone rod 220 through the light-transmitting hole 310 .

[0033] It is understandable that the end surface area of ​​the first end 221 is larger than the cross-sectional area of ​​the light-transmitting hole 310, and / or the cross-sectional area of ​​the light-transmitting hole 310 can be configured to be larger than the area of ​​the effective light-emitting area. The effective light-emitting area is the area of ​​the light-emitting chip 12 for emitting light, and the effective light-emitting area is smaller than the light-emitting surface of the light-emitting chip 12. In order to prevent the isolation member 300 from blocking the light, the cross-sectional area of ​​the light-transmitting hole 310 can be configured to be larger than the light-emitting area, thereby ensuring that the light is not blocked by the isolation member 300, thereby improving the energy utilization rate of the light-emitting chip 120. The end surface area of ​​the first end 221 is larger than the cross-sectional area of ​​the light-transmitting hole 310, which can prevent the cone rod 220 from being deformed by heat and extending into the light-transmitting hole 310 to abut against the light-emitting chip 120, thereby preventing blue light leakage and the like.

[0034] In one embodiment, please refer to Figure 1 , the isolating member 300 may be a sheet-like structure, and the isolating member 300 may be provided with a plurality of first limiting portions 320. Further, the plurality of first limiting portions 320 may be separately arranged at the edge of the isolating member 300. The substrate 110 is provided with a plurality of second limiting portions 111, and the first limiting portions 320 and the second limiting portions 111 may be respectively limiting holes and limiting columns, limiting grooves and limiting blocks that cooperate with each other. Exemplarily, the number of the first limiting portions 320 is two, and the number of the second limiting portions 111 is correspondingly set to two, and the two first limiting portions 320 may also be separately arranged at two ends of the isolating member 300 that are away from each other to improve the positioning accuracy of the isolating member 300. And when the first limiting portion 320 corresponds to the second limiting portion 111, the plurality of light-transmitting holes 310 correspond one-to-one to the plurality of light-emitting chips 120. The first limiting portion 320 and the second limiting portion 111 are used to complete the positioning and assembly of the plurality of light-transmitting holes 310 and the plurality of light-emitting chips 120 , thereby greatly shortening the installation time and further improving the installation accuracy.

[0035] In one embodiment, in order to prevent the first limiter 320 from blocking light from passing through the light-transmitting hole 310, the first limiter 320 is disposed at the edge of the isolating member 300, and the light-transmitting hole 310 can be opened in the middle of the isolating member 300. Furthermore, the first limiter 320 can extend in a direction away from the LED matrix light source, thereby transmitting the heat generated by the light-emitting chip 120 to the outside to ensure the working safety of the light-emitting chip 120.

[0036] For more details, please refer to Figure 1 as well as Figure 2Each first limiting portion 320 is provided with a first limiting hole 321, and the second limiting portion 111 is provided with a second limiting hole 112. The parameters such as the opening position, size, etc. of each first limiting hole 321 and the second limiting hole 112 can be the same. The light guide assembly 200 is provided with a plurality of limiting posts 230. Furthermore, the limiting posts 230 can be provided at one end of the bracket 210 away from the cone rod 220, that is, the edge area of ​​the bracket 210, so as to avoid the limiting posts 230 from blocking the cone rod 220. The limiting posts 230 can be inserted into the first limiting holes 321 and the second limiting holes 112. By inserting the limiting posts 230 into the first limiting holes 321 and the second limiting holes 112, the isolation member 300, the light guide assembly 200 and the light emitting chip 120 can be effectively positioned, thereby ensuring the stability and reliability of the light source device 1. In addition, multiple spacers 300 and multiple light emitting chips 120 are positioned at the same time, effectively shortening the installation time. This design also helps to simplify the production process, improve production efficiency, and reduce production costs. In another embodiment, the end of the limit column 230 close to the substrate 110 can be configured with a thread, which can be threadedly connected by a fastener so that the spacer 300 can be fixed between the light emitting chip 120 and the cone rod 220.

[0037] By adjusting the connection between the support 210 and the spacer 300, for example, by pre-tightening the connection between the support 210 and the spacer 300, the cone rod 220 and the surface of the spacer 300 can be kept slightly compressed, so as to avoid the single cone rod 220 having low dimensional accuracy and being unable to abut against the surface of the spacer, and to eliminate the installation error caused by the deviation of the incoming materials of the cone rod 220, so that each cone rod 220 can abut against the surface of the spacer. In addition, even if the first end 221 of the cone rod 220 is slightly deformed, it does not affect the coupling and transmission distortion of the light.

[0038] It is understandable that, to improve installation accuracy, each first limiting portion 320 may be provided with a plurality of first limiting holes 321, and each second limiting portion 111 may be provided with a plurality of second limiting holes 112. The installation accuracy of the light source device 1 may be improved by a plurality of mutually cooperating structures to reduce assembly errors.

[0039] Preferably, the limiting column 230 can be interference fit with the first limiting hole 321 and the second limiting hole 112 to improve the matching accuracy among the limiting column 230, the first limiting hole 321 and the second limiting hole 112, thereby improving the positioning accuracy among the isolation member 300, the light guide component 200 and the light-emitting chip 120, and improving the lighting quality of the light source device 1.

[0040] In another embodiment, see Figure 3 as well as Figure 4, the isolating member 300 may include a plurality of sub-isolating members 330, and the plurality of sub-isolating members 330 are arranged one by one corresponding to the plurality of light-emitting chips 120. The size of the sub-isolating member 330 is greater than or equal to the surface of the light-emitting chip 120 close to the isolating member 300, so that the sub-isolating member 330 can completely cover the corresponding light-emitting chip 120, and effectively prevent the thermally deformed cone rod 220 from contacting the surface of the light-emitting chip 120. The bracket 210 can also be positioned with the light source array 100 by means of the limiting column 230 penetrating the second limiting hole 112 of the substrate 110, so as to determine the relative position of the cone rod 220 and the light-emitting chip 120. Each sub-isolating member 330 is pressed against the light source array 100 by the first end 221 of the corresponding cone rod 220 and directly contacts the light-emitting chip 120, and each sub-isolating member 330 is provided with a light-transmitting hole 310, and the light-transmitting hole 310 corresponds to the corresponding light-emitting chip 120 at the same time. The light-transmitting hole 310 on each sub-isolator 330 can be configured to have a shape and size that matches the effective light-emitting area of ​​the corresponding light-emitting chip 120. At the same time, the uniformity and consistency of the LED lighting device are also ensured. The replacement cost of the sub-isolator 330 is lower and the maintenance is more convenient. The position of the sub-isolator 330 can be adjusted according to the different positions of the effective light-emitting area of ​​a single light-emitting chip 120. This configuration greatly increases the operability of the installation of the isolator 300.

[0041] Specifically, in this embodiment, please continue to refer to Figure 4 Each sub-isolator 330 may include an abutting portion 331 and a limiting portion 332 connected to each other. The light-transmitting hole 310 is provided in the abutting portion 331. The abutting portion 331 may abut against the light-emitting surface 121 of the light-emitting chip 120. The light emitted by the light-emitting chip 120 can be emitted from the light-transmitting hole 310 of the abutting portion 331. The limiting portion 332 is bent relative to the abutting portion 331 toward the light-emitting chip 120. The limiting portion 332 is disposed around the light-emitting chip 120 and is engaged with the light-emitting chip 120.

[0042] Furthermore, the limiting portion 332 can abut against multiple surfaces of the light emitting chip 120, and the limiting portion 332 can realize the positioning of the light emitting surface 121 and the light transmission hole 310 through multiple surfaces, so as to limit the movement of the light emitting chip 120 and the sub-isolating member 330 in the axial direction perpendicular to the light transmission hole 310. The sub-isolating member 330 is then pressed against the surface of the light emitting chip 120 by the corresponding first end 221, that is, the sub-isolating member 330 is clamped between the first end 221 and the light emitting chip 120, thereby limiting the movement of the sub-isolating member 330 along the axial direction of the light transmission hole 310, thereby realizing the complete positioning and installation of the sub-isolating member 330.

[0043] In a more specific embodiment, the limiting portion 332 may include a first sub-limiting portion 333, a second sub-limiting portion 334, a third sub-limiting portion 335 and a fourth sub-limiting portion 336, and the first sub-limiting portion 333, the second sub-limiting portion 334, the third sub-limiting portion 335 and the fourth sub-limiting portion 336 extend toward the direction close to the light emitting chip 120 to form an installation space 337, and the installation space 337 is connected to the light-transmitting hole 310. The installation space 337 is adapted to the corresponding light emitting chip 120 so that the light emitting chip 120 can enter the installation space 337. Further, the first sub-limiting portion 333, the second sub-limiting portion 334, the third sub-limiting portion 335 and the fourth sub-limiting portion 336 are arranged around the abutting portion 331, and an opening is formed on one side of the installation space 337 away from the abutting portion 331, and the light emitting chip 120 can enter the installation space 337 from the opening. The light emitting chip 120 includes a light emitting surface 121 and a first side surface 122, a second side surface 123, a third side surface 124 and a fourth side surface 125 which are arranged around the outer contour of the light emitting surface 121. The light emitting surface 121 abuts against the abutting portion 331, the first sub-limiting portion 333 abuts against the first side surface 122, the second sub-limiting portion 334 abuts against the second side surface 123, the third sub-limiting portion 335 abuts against the third side surface 124, and the fourth sub-limiting portion 336 abuts against the fourth side surface 125. The first side surface 122 and the third side surface 124 are arranged opposite to each other, and the first sub-limiting portion 333 and the third sub-limiting portion 335 can limit the abutting portion 331 from moving along the line connecting the first side surface 122 to the third side surface 124. The second side surface 123 and the fourth side surface 125 are arranged opposite to each other, and the second sub-limiting portion 334 and the fourth sub-limiting portion 336 can limit the movement of the abutting portion 331 along the connecting line direction from the second side surface 123 to the fourth side surface 125, so as to determine the positional relationship between the light emitting chip 120 and the isolation member 300, avoid the isolation member 300 from hindering the light transmission, and ensure that the light can be smoothly transmitted into the light transmission hole 310.

[0044] If the distance between the light emitting chip 120 and the cone rod 220 is too small, the cone rod 220 deformed by heat can easily pass over the isolation member 300 and abut against the light emitting chip 120, affecting the light coupling of the light emitting chip 120 into the cone rod 220. If the distance between the light emitting chip 120 and the cone rod 220 is too large, there will be serious loss in the transmission of light in the gap between the two. The thickness of the abutting portion 331 in this embodiment is 0.05mm-0.15mm, and the abutting portion 331 can abut against the first end 221 of the cone rod 220, so as to maintain the distance between the cone rod 220 and the light emitting chip 120, and ensure that the light can be efficiently coupled into the cone rod 220.

[0045] The light source device 1 provided in the present application has a light source array 100 that emits light during operation. The light passes through the light-transmitting hole 310 of the isolating member 300 and is coupled into the conical rod 220 to form a light source with high brightness and high uniformity. The light-emitting chip 120 generates heat during operation, and the conical rod 220 is deformed by the heat. However, the isolating member 300 abuts against the first end 221 of the conical rod 220, thereby limiting the deformation of the conical rod 220 toward the light-emitting chip 120 and maintaining the distance between the light-emitting chip 120 and the conical rod 220. The optical coordination between the light-emitting chip 120 and the conical rod 220 is ensured, the coupling efficiency of the light emitted by the light-emitting chip 120 at the first end 221 is improved, and the brightness and power of the light source device 1 are effectively improved.
