The utility model relates to the technical field of ship electric appliances, in particular to a high-end ro-ro passenger ship outdoor lighting lamp which is provided with a bulkhead, cable penetrating holes are formed in the bulkhead at intervals, a supporting pipe is arranged on the outer side of the bulkhead at the positions of the cable penetrating holes, one end of the supporting pipe wraps the cable penetrating holes and is fixedly connected with the bulkhead, and the other end of the supporting pipe is connected with a lampshade. A lamp tube is inserted into the lampshade, a cable jack communicated with an inner cavity of the supporting tube is formed in the lampshade, a wiring terminal is arranged on the lamp tube and connected with a cable, and the cable penetrates through the cable jack, then sequentially passes through the supporting tube and the cable penetrating hole and then is connected with a power supply on the inner side of the cabin wall. The cable has the advantages of simple structure, high communication efficiency in a design stage, no cable exposure, no fire, good aesthetic property, neat exterior and the like.

The application provides a high-thermal-conductivity diamond / copper composite material and an SPS sintering process thereof, raw material pretreatment: selecting three kinds of monocrystalline diamond particles with different particle sizes, mixing the titanium-plated diamond obtained after vacuum titanium plating treatment; solid dry powder mixing: uniformly mixing a solid additive and graphene modified copper powder to prepare a copper-based composite dry powder; nitrogen intermittent airflow suspension dispersion: adding the titanium-plated diamond into a sealed covering tank to make the titanium-plated diamond suspended and dispersed in the sealed covering tank; atomization covering makes the copper-based composite dry powder uniformly covered on the surface of the titanium-plated diamond to obtain composite particles; vacuum low-temperature degreasing to obtain the composite particles after degreasing, and SPS sintering demolding to obtain the high-thermal-conductivity diamond / copper composite material. The coating is uniform and dense, has no exposure and no agglomeration, and significantly reduces porosity and interface thermal resistance; the proportioning is accurate, the degreasing is thorough, and there is no residue; the generation of brittle phases is inhibited, and the interface combination is excellent; the thermal conductivity is stable and greater than 700 W / (m*K), and the density is greater than or equal to 99%.
