Due to the rapid development of the LED lighting market, its application range has evolved from single color and color conversion applications to general lighting applications such as residential, commercial and off-grid lighting applications, and eventually to outdoor lighting applications. According to Strategies Unlimited, the LED lighting market will exceed $5 billion in 2012, equivalent to a compound annual growth rate (CAGR) of 28% from 2008 to 2012.
From 2012, LED lights will be the only lighting source to replace traditional luminaires. Alternative luminaires include high-efficiency fluorescent lamps and high-intensity discharge lamps (HID). However, in order to achieve this goal, the LED industry will face many challenges, which will be discussed in the latest report from Strategies Unlimited.
"LED Lighting - Market Analysis and Forecast" made a detailed assessment of the market driving force and challenges faced by the LED lighting industry in the general lighting market. The assessment provides an application analysis and forecast for nine lighting markets that have grown to 2012. At present, LED lighting applications mainly include small markets such as export sign lights, architectural lighting, accent lighting, decorative lighting and entertainment lighting, many of which use red, green and blue LEDs. However, white light began to show its obvious advantages and strong potential, and white light has a huge market prospect.
The development prospect of white LED
White LED luminaires have begun to occupy a strong market position in alternative applications such as consumer portable lighting (such as flashlights, headlights) and solar landscape lighting, and more recently white LEDs have begun to be used for specific lighting. Applications such as retail display lighting, commercial and industrial lighting , and outdoor lighting.
In 2008, the number of white LED luminaires was only over 50% of the total LED lighting market. White LED luminaires provide quantifiable energy and cost savings compared to conventional luminaires, which will accelerate the use of white LED luminaires in general lighting.
With the improvement of LED luminous efficiency and cost reduction, LED will gradually cut into the indoor lighting field and the outdoor street lamp market after 2010. LEDinside estimates that by 2012, LED lighting will reach a scale of about $1.3 billion, with an annual growth rate of 33%.
Performance improvement
In recent years, LED technology has achieved dramatic performance improvements, and the efficacy of LED lighting has also improved. According to StrategiesUnlimited, between 2008 and 2012, the market share of white LED lamps will increase due to the high-efficiency white LEDs as commercial applications with a luminous efficacy of more than 100 lm/W.
Further improvement of the design of LED lighting fixtures can optimize the performance of LEDs, which is expected to promote the development of the LED lighting market. Economic development and large-scale production will further reduce manufacturing costs. The following describes a method for producing a low color temperature and high color rendering high power white LED.
Method for producing low color temperature and high color rendering high power white LED
This paper introduces the method of using high-power blue LED chip as the light source to prepare low color temperature and high color rendering white LED with phosphor conversion method and red LED compensation method, and analyzes two kinds of performance from high performance and application. The advantages and disadvantages of the method.
Gallium nitride, based blue, green and ultraviolet light-emitting diodes (LEDs), opened up new markets for LEDs, high-power LED lighting. The core of high-power LED lighting is white high-power LEDs. The methods for producing white light high-power LEDs include red, green, and blue primary color LED synthesis, blue LED+yellow phosphor, ultraviolet LED+tricolor phosphor, and multilayer organic electroluminescence (OLED). Taking into account the advantages of technology and cost, at present, blue LED chips + phosphors become the mainstream of white high-power LED technology.
