According to the latest report released by the LED Industry Research Institute, the LED packaging market in mainland China in 2012 was 39.7 billion yuan, a year-on-year increase of 24%.
Among them, the market size of LED high-power devices was 10.47 billion yuan, up 41.4% year-on-year; the market size of LED medium power devices was 4.34 billion yuan, up 37.7% year-on-year; the market size of LED low-power devices was 24.9 billion yuan, up 15.8% year-on-year.
The Institute expects that the LED packaging market in mainland China will maintain a growth rate of more than 16% in the next few years due to the gradual release of downstream application market demand.
Among them, the market demand growth of medium and large power devices will continue to be strong, maintaining a high growth rate of more than 30%, which will become the main driving force for the rapid growth of the packaging market in the next few years.
The market demand for LED low-power devices will continue to slow down in 2012.
With the explosive growth of the lighting market demand, there will be a demand for blowout in the medium and large power packaging market. The strong market demand and the continued high gross profit margin of the products have become the main reasons for most LED packaging companies to enter the field of high power packaging.
Medium and high power devices become the main source of illumination
Before 2009, the light source used in LED lighting products mainly used low-power devices and high-power 1W imitation lumens, but after 2010, with the series of devices such as medium power 2835, 5630, 3030, 3535, 5730, etc., gradually in the field of lighting The application and the rapid development of integrated packaging and COB packaging devices have gradually replaced the main light source of LED lighting with medium and high power. The main reasons for the above product substitution are as follows:
The small power devices represented by 3528, 3020, and 3014 have a single structure and small size. Although they are used in small and medium power lighting fixtures, there is no spot in the medium and small power lighting fixtures, but the total cost of the light source is higher than that of the medium and high power devices. Higher, overall thermal performance is limited.
The medium and high power devices represented by series 2835, 5630, 5730, COB package, integrated package, etc. have become one of the ways to reduce the cost of lighting fixtures. As the price of LED lighting fixtures continues to decline, the gross profit margin of LED lighting manufacturers is greatly squeezed.
According to industry statistics, the average gross profit margin of LED lighting fixtures reached more than 45% in 2010, but by the end of the first quarter of 2013, this figure had dropped to 30.5% or even lower. Therefore, many companies are currently seeking ways to reduce the cost of LED lighting indirectly by reducing the cost of light sources. Series 2835, 5630, COB package, integrated package and other products have gradually become the main light source of LED lighting with its high cost performance.
In 2012, most LED packaging companies have taken the field of LED lighting as the focus of market development, especially indoor lighting, outdoor lighting, and backlight display have become the preferred target markets for medium and large power packaging companies.
According to industry statistics, the market size of LED lighting in China in 2012 exceeded 105 billion yuan, a year-on-year increase of more than 42%. It is expected that the LED lighting market in mainland China will maintain a growth rate of more than 30% in the next two years.
Industry experts predict that the LED lighting market in mainland China will maintain a rapid growth trend in the next few years, especially indoor lighting and outdoor lighting will become the main driving force for the rapid growth of the lighting industry.
The rapid growth of LED lighting market demand is conducive to the continuous growth of demand for high-power devices in LED market. Since 2009, medium and high power devices have gradually become the main source of LED lighting, and maintain high gross profit margins for a long time.
As of the end of the first quarter of 2013, the number of lighting fixtures using medium and high power devices as the main source of light accounted for more than 67%, and it is expected that this proportion will reach more than 80% in 2015.
Medium power devices occupy small and medium power lighting
The report pointed out that the medium and large power devices are cost-effective. Among them, the 2835, 5630 (0.2-0.5W) series products will reduce the number of the above-mentioned devices by more than 50% under the same power, and the corresponding lamp cost reduction is more obvious, becoming medium and small power. Lighting fixtures are preferred; COB packaging and integrated packaging are the best choice for high-power lighting fixtures due to their high overall efficacy, good spot size and low cost.
Among them, in the medium and small power lighting products, the medium power device light source is used, not only the device uses more than 50% less than the low power device, but also the light source cost is lower than the low power light source cost.
In the field of small and medium power lighting fixtures, medium power package devices are gradually replacing small power devices as the main source of light.
As of the end of the first quarter of 2013, more than 70% of the light sources used in small and medium power lighting fixtures have selected medium power packaged devices.
Among them, fluorescent lamps, bulbs, panel lamps, ceiling lamps, ceiling lamps, etc. use more than 75% of the medium power devices 2835, 5630, 5730 series; downlights, spotlights/PAR lights, track lights, table lamps, etc. More than 80% of the light source used is a high-power series such as COB package, integrated package, and 1~3W imitation lumen.
The series of devices such as 3528, 5050, 3020, 3014, and F5 straw hats were the most demanding devices on the market before 2009. As of the end of the first quarter of 2013, a small number of them were still used in fluorescent tubes and bulbs. Most of the small and medium-sized power lighting fixtures, such as corn lamps and candle lamps, are widely used in landscape lighting , such as lamp strips, soft/hard strips, string lights, and indications.
