langkah itu berbeza kerana litar telah menambah 1 lagi diod dan ini boleh dibuktikan bahawa diod
the step is different because the circuit has added 1 more diode this can be proved that the

badan berada pada voltan rendah. diod badan sumber dimatikan. diod badan longkang mati. tiada arus mengalir. transistor dimatikan.
body is at at high voltage:voltage. source body diode is off. drain body diode is off. no current flows. transistor is off.

pasar diod pemancar cahaya (led) telah berkembang baru-baru ini, berkat peningkatan kecekapan bercahaya led. walaupun begitu, kira-kira 70% daripada jumlah tenaga yang dipakai oleh lampu led dipancarkan sebagai haba, menimbulkan masalah terma. tanpa menghilangkan panas ini dengan betul, prestasi dan jangka hayat lampu led akan terganggu. oleh itu, untuk mengkomersialkan lampu led, masalah pelesapan haba mesti diselesaikan terlebih dahulu. singki haba perolakan semula jadi sesuai untuk lampu led, memandangkan kelebihan keseluruhannya
the light-emitting diode (led) market has grown recently, thanks to enhancements in led luminous efficiency. nevertheless, about 70% of the total energy consumed by an led light is emitted as heat, creating a thermal problem. without properly dissipating this heat, the performance and life of an led light is impaired. thus, to commercialize led lights, the problem of heat dissipation must be solved first. natural convection heat sinks are appropriate for led lights, in view of their overall advantages.
