From the actual use situation, LED indoor lighting is roughly divided into industrial, commercial and home applications. Industrial indoor lighting is a market where LEDs are cut early and demand is large. The demand for products is more focused on safety, energy saving and long life. For example, industrial and mining lamps generally take high-quality, energy-saving routes and save costs. Commercial lighting focuses on scene effects and user experience, and sometimes introduces special lamps with different angles of color temperature and color rendering for various application environments; while home lighting tends to pay more attention to cost performance, the current characteristic of this field is that it is used in home applications. Mainly downlights, bulbs, etc. have entered the era of low cost. Quality reliability needs to be improved Recently, the proportion of LEDs in the field of general lighting has increased rapidly. It has opened up a broader world for the application of LED indoor lighting in the commercial field. This market is generally mostly for engineering procurement, and the demand for products is large. Therefore, it has become a key market that every manufacturer is striving for now. On the other hand, the general civil lighting market has also been fully opened, and its development speed can not be underestimated. More and more manufacturers have introduced relatively mature LED lighting products, and some products have broken through the traditional lighting in terms of functions and design. category. However, while the indoor lighting is developing rapidly, there is still a big gap in the application market's perception of the quality of LED lamps. LED indoor lamps have many advantages, such as energy saving, long life, safety and reliability, etc., Wu Hongfeng, sales director of Jiangsu International Sales Department Co., Ltd., but in many practical cases, because the end user's perception of LED is not comprehensive, In order to attract users' attention and rapidly increase market share, some merchants have used poor products and technologies, such as: for the brightness, abandoned the life; in order to save energy, abandoned the security, so that some terminal market feedback information is: LED lights have Good, but most are easy to break and the price is not cheap. In response to the negative impact of this short-term interest behavior, he further pointed out that the lighting market is undergoing a new round of changes, including the friction between the traditional lamps and LED lamps, once the advantages of LEDs Being artificially manufactured into shortcomings will make market promotion more difficult, especially in the initial stage of the LED application market being opened. Therefore, enterprises in the industry are urgently required to consciously abide by the technical and quality standards and jointly build a healthy industry development path. Taking the current thermal management problem that has a great influence on the quality of LED indoor bulbs as an example, although LED lighting can significantly save energy, the overall life of the bulb is said to be 30,000 to 50,000 hours; in fact, often because of LED Many components in the drive circuit, especially electrolytic capacitors, age with increasing temperature, causing excess heat in the retrofitted luminaire to significantly reduce the life of the solid-state lighting bulb, which also allows consumers to expect a high quality LED luminaire. discount. Hubie Notohamiprodjo, Director of Solid State Lighting Product Marketing at Dialog Semiconductors, explains that the main reason for these problems is that some bulb designers are unclear about the environment and state of use of the bulb (for example, in closed luminaire systems where air flow is limited, or air freedom). Flowing open luminaire systems), and sometimes poorly designed thermal energy systems are used in applications where air flow is limited, resulting in overheating of the luminaire and greatly reducing the life of the solid state lighting bulb. In order to effectively solve the above problems, unlike ordinary integrated circuits, which have a thermal shutdown device and cut off the design of the integrated circuit only in a high temperature environment, Dialog's LED driver uses a patented overheat protection (OTP) derating technology at high temperatures. In the environment, the driving current into the LED is automatically reduced in a small step size; when the temperature is lowered, it seamlessly restores the brightness, by reducing the operating temperature in the low-flow bulb environment, avoiding it exceeding the rated temperature of the electrolytic capacitor, and Helps achieve predictable lamp life. Achieving the best price-performance ratio of LED indoor lighting is still largely related to the decline in product prices. In particular, the biggest challenge in the development of indoor lighting is how to achieve a suitable price point for the product, while at the same time achieving reasonable Performance and safety standards. Among them, the cost of the LED lamp 30 is spent on the drive control circuit, so the cost reduction of the control circuit including the LED driver IC is very important, which also requires the chip manufacturer to continuously introduce innovative and more cost-effective technical solutions. The price of LED light sources is declining, but the driving electronics technology has not been much innovative, and the price has been high, which has brought pressure on product costs. Guan Zhenyuan, technical marketing manager of Marvell's LED driver chip product line, said that dimmable LED lamps will become the mainstream products in the market, but a key point in the development of LED lighting driver ICs is the compatibility of dimming, which directly affects users. The use experience, because LED lighting mostly uses the current drive mode, and the existing dimmers are mostly voltage dimming, so there are certain difficulties in compatibility. At the same time, further increasing the integration of the chip to reduce the size of the power supply is also the main direction for the future development of the LED power supply. According to reports, Marvell uses a unique mixed-signal architecture and built-in advanced digital algorithms, which greatly enhances integration and reduces product cost. Marvell's cost-effective chip solution this year has reduced the price of dimming products from $1.50 to less than $1 last year. It is expected that by 2016, dimming bulbs will be close to non-dimming prices, thus accelerating the popularity of LED lighting. For the development of dimmable luminaires, Notohamiprodjo analyzed: The main obstacle at present is the compatibility of dimmers, including compatibility with various existing dimmer technologies, such as TRIAC-based, low voltage (0~10v). Linear and PWM dimmers are also compatible with next-generation electronic dimmers; and electronic dimmers have proven to be more difficult to interchange than traditional passive TRIAC dimmers. Another big problem is that many of the most demanding regulations around the world raise requirements for PFC (power factor correction) and input harmonics. For example, ENERGY STAR requires LED luminaires to be adjustable down to measurable light. 10 Energy Star and European Power Manufacturers Association (IEC61000-3-2) require residential lighting with a power factor greater than 0.7 and commercial lighting with a power factor greater than 0.9, and it is not easy to maintain overall performance and control costs. To solve the previous problem, from the overall development trend, it is turning to a smarter controller to effectively handle the electronic dimmer. For example, Dialog uses patented technology to determine the type of dimmer and provide an automatically adjustable algorithm through the principles of digital analytics. This intelligent controller provides a variety of dimmers (including new electronic tune) in a more intelligent way. Lighter) better compatibility. To achieve the best balance between the performance and cost of the luminaire, Notohamiprodjo believes that using a more optimized circuit design and eliminating additional discrete components to reduce costs may be an ideal solution. For example, Dialog's driver, the iW3640, automatically and seamlessly implements warm-toned light in a single integrated circuit. Previously, external integrated color control components were required in the integrated circuit. The iW3640 eliminates the external MCU required for traditional warm-tone technology by integrating the driver for driving the second LED string and using a digital engine to control the conversion process. The cost of the backup power supply. At the same time, this can also reduce the bill of materials (BOM) cost of A19SSL and PAR bulbs with equivalent power of 75~150W and commercial external dimmable ballasts of 20~45W. Moving toward intelligent lighting systems In many LED indoor lighting applications, one of the more prominent features is the user demand for decorative lighting. For example, in some high-end hotels, shopping malls and office buildings, bars and cafes and other leisure venues, museums and art galleries and other professional exhibition venues, users generally require LED lamps to take full advantage of the full spectrum of any color and dynamic static lighting effects, combined Different application styles bring more intelligent atmosphere lighting effects to the owners. Wu Hongfeng said: More novelty, special design, and multi-functionality are a new development goal of LED indoor lighting. Light is no longer a simple visual lighting tool, but a combination of emotion, signal and creativity. Especially the integration with smart home. Light can express time, temperature, mood and other signals, and can also express various emotions. For the luminaire, it may be necessary to let go of the extensive illuminating thinking, and deal with each beam more delicately, while reducing light pollution and improving utilization efficiency. He exemplified that with the application trend of intelligent and Internet, the lighting function of LED light source will be extended continuously: such as using a smart terminal such as a mobile phone to control the light environment; based on the Internet big data background, using LED lights as a micro base station, pushing each Practical information to the customer's mobile terminal and so on. In the mode of multi-industry entering cross-border development, the application prospect of LED civil lighting has been expanded into an infinite imagination space, and its demand will be much higher than commercial lighting. It is also reported that Wenrun Optoelectronics will set up a device R&D center in South Korea this year, and since 2013, the company has invested heavily in the research and development of applied products. Taking advantage of the manufacturing of light source, Wenrun Optoelectronics has signed a cooperation agreement with Nordic enterprises to jointly develop intelligent LED home lighting systems and LED lighting systems in special fields in combination with the existing general LED lighting products such as Aurora and Qixing. In the process of integration of LED lighting and intelligent systems, the development of intelligent lighting platform technology is a major focus. Although intelligent lighting is defined in many ways, we believe that smart lighting first includes solid-state lighting control, Notohamiprodjo said, such as various wired digital dimming modes through AC wires (such as toggle switch dimming), and the emerging Ledotron/ DLT (IEC62756-1) digital lighting standard. In addition, smart lighting should also include wireless lighting control technologies through existing wireless standards such as Bluetooth Smart, ZigBee, Z-Wave, Wi-Fi. Dialog's recently announced SmarteXiteiW6401LED driver is designed for a wide range of smart lighting applications, including dimming control via line to support Ledotron/DLT (IEC62756-1) digital dimming. The drive also includes an I2C bus that seamlessly integrates many types of digital and wireless networks, including BluetoothSmart, ZigBee, and Z-Wave. For example, users can use a smartphone to control lighting, and the drive also incorporates Easy to configure non-volatile memory. For the popularization and promotion of intelligent lighting, Guan Zhenyuan particularly emphasizes the user experience and system construction costs. In the development of LED power driver products, Marvell provides a four-in-one integrated intelligent lighting solution including lamp driver control, wireless gateway, cloud and APP. The system revolves around innovative LED driver ICs (such as the latest 88EM8189). Built with low-power ZigBee networking, it not only provides high integration, high performance, low cost solutions for LED lights and gateway hardware platforms, but also helps LED lights based on Marvell's deep understanding of lighting and mature software support. ODM/OEMs achieve the best user experience. In addition, Marvell's technical advantages and complete solutions in wireless connectivity technology and even in integrated chip solutions can also provide a strong backing for intelligent lighting and its connectivity technology.
