[0035] In various embodiments, electro-optical device 200 includes a transparent layer 210, a heat sink 204 mechanically coupled to transparent layer 210, an electronic circuit system 214 disposed on a substrate 208, and a support 216 configured to mechanically couple heat sink 204 to the electronic circuit system.

[0036] In various embodiments, transparent layer 210 includes at least one of a lens, a lens array, a protective layer, and / or a refractive filter. For example, a lens or lens array can focus or otherwise manipulate incident light beam 234 onto various portions of one or more photosensitive components 222 on electronic circuit system 214. In some examples, transparent layer 210 can serve as a protective layer for one or more photosensitive components 222. In various embodiments, transparent layer 210 is made of at least one of glass, plastic, and / or any other transparent material.

[0037] In various embodiments, electro-optical device 200 can be a light receiving device as described above, or can be a light emitting device. Electronic circuit system 214 can include one or more light emitting components, and transparent layer 210 can be configured to pass emitted light through or otherwise manipulate the emitted light, such as by collimating the emitted light. In various embodiments, heat generated by emitting light, receiving light, and / or various operations of electronic circuit system 214 can be dissipated to the environment using heat sink 204.

[0038] In various embodiments, the heat sink 204 includes an opening configured to be embedded in the transparent layer 210. For example, the heat sink 204 can include a cutout configured to fit within the transparent layer 210.

The heat sink 204 can, for example, include a boss 240 configured to support the transparent layer 210. The boss 240 can be located between the transparent layer 210 and the support 216.

[0039] In various embodiments, the heat sink 204 is mechanically coupled to the transparent layer 210 at one edge using a layer of glue 236 and directly coupled to the transparent layer 210 at another edge 238. For example, the boss 240 of the heat sink 204 can be mechanically coupled to the support 216 using a layer of glue 236.

[0040] The electro-optical device 200 can include a cavity created between the support 216, the transparent layer 210, the electronic circuit system 214, and / or the heat sink 204. The cavity can be a hollow area through which the incident light beam 234 passes after passing through the transparent layer 210, or through which the light emitted by the electro-optical device 200 passes before reaching the transparent layer 210. In various embodiments, the boss 240 of the heat sink 204 can protrude into the cavity. In various embodiments, the boss 240 of the heat sink 204 can be flush with the support 216. In various embodiments, heat generated by emitting light, receiving light, and / or various operations of the electronic circuit system 214 can pass through the cavity and / or through the support 216 to reach the heat sink 204. In various embodiments, the support 216 is made of a thermally conductive material, such as a thermally conductive adhesive.

For example, heat sink 204 can be circularly circumscribed around transparent layer 210 and / or the cavity. In some examples, heat sink 204 can be oval, square, or any other geometric shape surrounding transparent layer 210. In some examples, support member 216 can be a single piece, for example, having an annular shape that mechanically couples a single-part heat sink completely surrounding the transparent layer.

[0042] In various embodiments, the heat sink 204 includes multiple portions, each of which is mechanically coupled to one side of the transparent layer 210. For example, the heat sink 204 can include a first heat sink portion 202 and a second heat sink portion 206. The first heat sink portion 202 can be mechanically coupled to one side of the transparent layer 210, and the second heat sink portion 206 can be mechanically coupled to the other side of the transparent layer 210.

[0043] In various embodiments, support member 216 mechanically couples heat sink 204 to electronic circuit system 214. Support member 216 can have various shapes and / or mechanical forms.

First post 220 can mechanically couple to a first boss of heat sink 204, and second post 218 can mechanically couple to a second boss of heat sink 204.

[0044] In various embodiments, support member 216 transfers heat generated by electronic circuit system 214 to heat sink 204, where it is then dissipated into the environment. In various embodiments, first post 220 is configured to mechanically couple a first heat sink portion to the electronic circuit system and transfer heat generated by the electronic circuit system to the first heat sink portion. In various embodiments, second post 218 is configured to mechanically couple a second heat sink portion to the electronic circuit system and transfer heat generated by the electronic circuit system to the second heat sink portion.

[0045] In various embodiments, the support member 216 is made of a thermally conductive material. For example, the support member 216 (such as the first column 220 and the second column 218) is made of a thermally conductive glue.

[0046] In an exemplary embodiment, the support 216 and the heat sink 204 are configured to reduce the thermal resistance from the electronic circuit system 214 to the environment surrounding the electro-optical device 200. For example, by using a heat sink 204 embedded in the transparent layer 210, and for example by Figure 1 Compared to the electro-optical device 100 shown in which the transparent layer 106 is surrounded by resin, the thermal resistance of the path from the electronic circuitry 214 to the environment is reduced.

[0047] Therefore, in an exemplary embodiment, in electro-optical device 200 , support 216 and heat sink 204 are configured to maintain the maximum junction temperature of the electronic circuitry below a maximum junction temperature threshold. This can reduce the likelihood of malfunctions due to temperature increases in electro-optical device 200 .

[0048] In various embodiments, heat sink 204 includes first heat sink portion 202 and second heat sink portion 206. First post 220 can be configured to mechanically couple first heat sink portion 202 to electronic circuitry 214, and second post 218 can be configured to mechanically couple second heat sink portion 206 to electronic circuitry 214.

[0049] In various embodiments, the heat sink 204 includes one or more fins. The heat sink 204 may include, for example, one or more first fins 230, for example, on the first heat sink portion 202, and one or more second fins 228, for example, on the second heat sink portion 206. The one or more fins are configured to increase the heat exchange surface between the heat sink and the environment and increase the heat dissipation of the heat sink to the environment.

[0050] In various embodiments, the heat sink is made of copper or a copper alloy. Copper has high thermal conductivity and can increase the heat dissipation of the heat sink.

[0051] The electronic circuit system 214 may include one or more light-sensitive components 222. The one or more light-sensitive components 222 may include, for example, photodiodes, pixels, light sensors such as infrared sensors, transistors, etc. In an example, the one or more light-sensitive components 222 are a pixel array.

[0052] In various embodiments, electronic circuit system 214 is disposed on substrate 208. Electro-optical device 200 can be a wire-bonded electro-optical device. For example, electro-optical device 200 can include one or more bonding wires 212. One or more bonding wires 212 can be configured to electronically couple electronic circuit system 214, or components of electronic circuit system 214, to one or more conductive traces of substrate 208.

[0053] In various embodiments, the electro-optical device 200 may include a molding material 224. The molding material 224 may be configured to surround the support 216 and mechanically couple to the heat sink, the support, the electronic circuitry, and the substrate and hold them together. In an example embodiment, the molding material 224 increases the mechanical robustness of the electro-optical device 200. The molding material 224 may include a resin. In an example embodiment, although the molding material 224 may have a high thermal resistance, the use of a heat sink and a low thermal resistance path from the electronic circuitry 214 to the heat sink 204 allows heat dissipation and maintains the maximum junction temperature below the maximum junction temperature threshold. Therefore, in an example embodiment, the electro-optical device described herein provides high mechanical strength and high heat dissipation.

In various embodiments, the one or more first fins 230 and the one or more second fins 228 are configured to increase the heat exchange surface between the heat sink and the environment and increase heat dissipation of the heat sink.
