The invention relates to a voltage-withstanding high-power LED lamp array. The LED lamp array comprises a lamp body, wherein cavities are formed in the two sides of the lamp body respectively, a metalheat dissipation plate is fixedly connected into the cavity in one side of the lamp body, multiple aluminium alloy heat dissipation plates are sequentially arranged from inside to outside around thecenter of the metal heat dissipation plate on the surface of the metal heat dissipation plate, a ring slot is formed between every two adjacent aluminium alloy heat dissipation plates, a ring slot isformed between the outermost aluminium alloy heat dissipation plate and the inner wall of the lamp body, an LED metal substrate is installed in each ring slot, and all the LED metal substrates are fixedly connected with the metal heat dissipation plate. The LED lamp array is suitable for all sea-depth conditions and has good corrosion resistance, heat dissipation performance, voltage-withstandingperformance and an illumination effect; and the lamp body is made of a titanium alloy material, the red copper heat dissipation plate and the aluminium alloy heat dissipation plates are installed in the lamp body, the problem of poor heat dissipation performance in a traditional structure is solved through the advantages that red copper and aluminium alloy have a high heat conduction rate and large specific heat capacity, and the heat dissipation performance of the LED lamp array is effectively improved.

The invention relates to a thermal shoe. The thermal shoe comprises a sole, a vamp, a shoe tube, a heating device, a circulation groove, a waterproof layer, an exhaust groove, a blocking sheet, a protective soft board, a groove, a micro cylinder, a water storage tank, a gas permeable membrane, a water injection tank, a bucket and a first magnetic block, wherein when the bucket closes an opening ofthe water injection tank, the bucket and the sole are squeezed; after the heating device is started, water in a water outlet groove is heated to be evaporated to form water vapor passing through thegas permeable membrane and entering the circulation groove, since the specific heat capacity of the water is larger, a warm state can be maintained for a long time, and since the water vapor increases, the gas pressure can increase to jack up the blocking sheet, therefore the water vapor escapes from the shoe tube; the water in the water outlet groove needs to be supplemented regularly, the bucketis rotated, thereby putting the water into space formed by the bucket, then the bucket is rotated to transfer the water into the water injection tank; the first magnetic block can enhance the connection strength between the bucket and the sole and enhance the sealing property.
