Attacking intelligent lighting LED driver IC factory package plan

Light-emitting diode (LED) driver IC manufacturers will use the Turnkey SoluTIon solution to enter the Smart LighTIng market. In Germany's "Light+Building" in 2014, Samsung, LG, OSRAM, Philips and other international brands show their LED smart lighting solutions. , once again sizzling the topic of intelligent lighting.

Replacing the traditional light source, increasing the proportion of LED intelligent lighting, popularizing

At the same time, semiconductor manufacturers are also targeting the smart lighting market, and are developing their core technology resources to develop a turnkey solution that integrates sensors, controllers and LED driver ICs to help start-up equipment manufacturers (OEMs) and The Design Manufacturer (ODM) has significantly shortened product design time to grab the business opportunity in the smart lighting market.

LED has the advantages of high luminous efficiency, adjustable color and brightness. In the future, it has been determined that it will take over the traditional light source to become a new generation of lighting. Therefore, with the replacement of traditional light sources such as incandescent lamps, tungsten halogen lamps and fluorescent lamps, the proportion of LEDs has gradually increased. Increase, the penetration rate of smart lighting market will also have the opportunity to expand rapidly.

Since the LED luminous efficiency has exceeded 100 lumens per watt on average, far beyond the traditional illumination source, the LED light source can adjust the color temperature to change the color and control the brightness through the driving IC, which is in line with the color and brightness of the intelligent illumination through the light source. The switch caters to the end user's appeal in different application scenarios and achieves the goal of energy saving and environmental protection. It has been regarded as the mainstream of future intelligent lighting sources.

NPD DisplaySearch analyst Yan Qingwei expects that the introduction of LED light sources for intelligent lighting has become the trend of the times. Therefore, it is estimated that by 2017, when the proportion of LED light sources replacing traditional light sources approaches 50%, the intelligent lighting market will enter a rapid growth period.

According to the market research organization NPD DisplaySearch, the penetration rate of LED bulbs and lamps in 2014 will reach 16.4% and 10.9% respectively, and will increase to 28.2% and 38.6% respectively in 2016.

Huang Daoheng, director of the Ronda Electronic Lighting Products Division, said that the application of LED lighting sources for intelligent lighting in the future can be divided into two categories. One is public lighting such as street lamps, and the light source will be replaced by high-pressure sodium lamps into LEDs. The control method achieves the purpose of energy saving; the second is consumer lighting, such as home lighting, commercial lighting, etc., which can change the color and brightness of the LED light source to create a comfortable or atmosphere.

Ronda Electronics has partnered with home lighting applications and plans to release smart lighting products with integrated sensors, wireless technology, LED light sources and driver ICs by the end of 2014. The main customer base will be locked in the original design manufacturer (ODM). ).

Figure 1 Lance Zheng, director of technical marketing, said that the digital dimming LED driver IC can save more BOM cost, and the unit price is comparable to the analog dimming solution.

Lance Zheng (Fig. 1), director of technology marketing at Marvell, believes that 2014 will be the first year of smart lighting development under the influence of more international brands, and the factors that will grow in the future will come from terminal sales. Price and user experience, where the selling price must be less than $10, and provide a friendly user experience, will help to increase consumers' willingness to purchase.
