Including China, many countries in the world have formulated policies to phase out incandescent light bulbs in stages. For example, in 2015, China plans to eliminate all of the incandescent bulbs for general lighting above 60W. Especially since January 1, 2014, after the US government announced a comprehensive “banâ€, the North American market is gradually becoming a new industry growth hotspot. The demand for LED lighting is booming, and LED lighting products are beginning to enter the homes of ordinary people. This huge market prospect has attracted many OEMs including ROHM.
In 2014, everyone said that this will be the year of LED lighting, and the development of LED intelligent lighting market is also advancing by leaps and bounds. With the Internet of Things Dongfeng, the LED intelligent lighting market is hot. The industry's focus on LED smart lighting in terms of low power consumption/energy saving, wireless control, dimming color adjustment and user experience is also a top priority. In this field, ROHM has also launched a series of LED intelligent lighting solutions in combination with its own advantages. At the Guangzhou Lighting Exhibition, ROHM exhibited integrated communication LSIs and LEDs such as ZigBee® LSI and Blutooth® Low Energy LSI. Driven wireless control solutions, battery-free remote control luminaire switching solutions have caused a sensational effect, attracting a large number of professional visitors to visit and negotiate.
ROHM has shown strong technical strength in the field of automotive LED lights, headlights, taillights, general lighting, outdoor lighting, etc., showing LED related technologies (LED light source, components, modules, driver ICs) to terminal lighting. A wide range of products and advanced technologies. It can be said that it is a combination of integrated semiconductor manufacturers' technology, which combines driving IC products, discrete semiconductor products and component products to bring comprehensive lighting solutions for daily life work.
Among them, in the "LED driver design" program, ROHM fully exploits the advantages of comprehensive semiconductor manufacturers, using high-quality products ranging from "LED driver IC" to "discrete components", "power modules" and "LED light sources". Group, bringing a variety of design solutions for bulbs, downlights / spotlights, large LED lighting. Based on this standard specification, the company optimizes the design according to the customer's specific requirements for products, standards, specifications, dimensions, voltages, etc., such as 2-channel LEDs for small LCD backlights such as smartphones and portable game consoles. The driver BD65B60GWL is a newly introduced superior LED driver IC product. It uses a unique high-precision DAC dimming technology to adjust the uneven illumination of each channel LED and suppress the uneven brightness of the LED, thus achieving a uniform brightness LCD backlight.
According to our understanding, ROHM's LED-related products are very rich, and can provide customers with a full range of products from upstream to terminal. In terms of "LED light source design", ROHM has been engaged in the development and sales of LED patches for many years, and has accumulated rich technical experience. Through continuous innovation, we have developed new "LED light source modules" for various applications, from fluorescent lamps, downlights to street lamps for commercial, decorative and public facilities, as well as various LED patches for general household bulbs. .
In the LED driver IC, we also make great efforts, insist on research and development and innovation, and take the lead in the industry. Provides easy-to-control drivers in all directions, including lighting solutions that support wireless communication technologies such as Bluetooth and ZigBee, and reference designs for PWM and TRIAC dimming. On the LED power module, there are also many advantages, such as low ripple high quality PAP38 power supply, large output LED lighting power supply (support PWM dimming and WIFI), medium and large PF LED lighting power supply.
Especially worth highlighting is an LED intelligent lighting solution based on battery-free wireless communication technology control, which has the powerful advantage of remote control of lamps without battery. The mechanical energy acquisition module can convert mechanical energy (such as the mechanical energy of the finger pressing switch) into electrical energy, and supply the module to work. It can be applied to products such as wireless passive switches, and has great application prospects in intelligent lighting control. ROHM is the founder of the first Eonson Alliance in Asia. As a key member, ROHM is fully conducive to energy harvesting technology, wireless communication technology and low-power technology accumulated in the semiconductor development field. It is actively developing innovative application products to provide customers with more Cost-effective smart lighting solution.
In ROHM's intelligent lighting solutions, the wireless remote-controlled ceiling lamp solution based on 2.4 GHz ZigBee communication technology has also attracted many viewers to consult. The solution supports PWM dimming, PF greater than 0.9, and built-in 8-bit MCU wireless IC. It is an ultra low standby power design. It is equipped with ROHM's built-in up/down circuit LED driver IC (BM1050F) and dimming LED driver IC (BD7681F), and incorporates its LAPIS Semiconductor digital technology - Zigbee control IC with built-in low-power MCU (ML7275) ), you can dim the color through the remote control to achieve intelligent lighting.
As a comprehensive semiconductor manufacturer with more than 50 years of history, ROHM will showcase the indispensable products and technologies in the field of LED lighting with its accumulated technology, reliability and consistently high quality. ROHM also exhibited a single-channel LED driver with built-in buck-boost DC/DC converter for automotive LED lights, headlights and taillights in the automotive electronics industry, which is constantly evolving in demand and market development. A practical LED driver reference design that caters to local customers' needs, such as AC/DC reference designs with built-in MOSFETs.
In LED intelligent lighting, ROHM combines LED driver chip technology, LED light source technology, advanced communication technology, ultra-low power technology, LED module technology, fully integrate existing components, and is committed to its diversified products and technologies. Provide comprehensive solutions for LED intelligent lighting. Give full play to the advantages of one-stop service from IC to electronic components, and strengthen the field of intelligent lighting through LED driver ICs, analog power ICs, SiC power components, LED chips, discrete components, sensors and other high-quality products. .
