At the booth of Guangya Exhibition, ROHM exhibited the insulated high-power LED driver BP5870, and claimed to have built-in PFC circuit with active filter method, which made the power factor reach 0.99. Furthermore, the BP5870 uses an analog resonant switching method that achieves low noise and high efficiency, so it can significantly reduce the switching loss of the switching MOSFET, resulting in an efficiency of 83%. Finally, there are many problems in the production of LED lighting devices, such as power supply design, housing design, LED layout design, etc. The BP5870 has been equipped with AC/DC converter, PFC circuit, DC/DC converter, and the user is in layout design. And the heat dissipation design does not need to work hard on the power supply design. For example, the EL model placed in the showcase, curved, is similar in appearance to the OLED embedded in the outside of the GE booth. Also, high-heat-resistant, high-power white LEDs (105lm/W) for lighting applications, high-efficiency (96lm/W) SMLV36/W36 white LEDs for thin-film applications, and high brightness for backlighting and lighting applications. The high-heating PSML3 series of white LEDs are scattered around the booth, and some are directly placed in the fixtures. In addition, the author also saw many new technologies on the stand, or an innovative design concept combining semiconductor and LED lighting. Among them, LED downlights with environmental dimming function, the demo system diagram shown on the poster; from morning (Ma Liang: 600-800lx), noon (very bright: 1500-1800lx), dusk (dark: 100- 300lx) to night (very dark: 0-100lx), the power consumption of the product is about 1.9W, about 0W, about 3.7W, about 5.7W. LED downlight with ambient dimming function. The current LED lighting power is 0.06W, and the current outdoor light brightness is 730lx. WYSIWYG, the cars and big trucks in the picture all illustrate the use of the product. Here, ROHM's non-insulated module can wirelessly remotely control the lighting of the entire building.
