Analysis Of Manufacturing Technology And Market Development Trend Of LED Fluorescent Tubes In China
Feb 22, 2018

LED Fluorescent lamp Market in China the current sales price for ordinary people's consumption habits and consumption capacity, or appear to be somewhat high, but because of its energy-saving, environmental protection, long life and other characteristics, in the parking lot, commercial lighting and other fields have been widely used. According to the research report of the LED industry Institute of Senior Engineers (GLII), 2012 China LED fluorescent Tube market size reached 6 billion yuan. With LED fluorescent tube price After many photoelectric enterprise's efforts in the continuous downward and photoelectric lighting technology is also increasing, LED fluorescent tubes are increasingly widely used in various fields of application, is expected to 2013 China led fluorescent Tube market scale growth will be more than 60%.

China LED fluorescent Tube manufacturing technology and development process.

The development of LED fluorescent tube manufacturing technology in China has lagged behind the international market, but its development rate is much higher than that of other similar economies. 2005 China LED fluorescent Tube enterprises began mass production, but at that time due to led point light source, led cooling shell, led driving power, and other technical restrictions, LED fluorescent tubes generally have low light efficiency, service life is not long, high maintenance rate, safety and other defects, but with the LED packaging device technology, LED shell cooling, led thermal board, led driving power and other technologies to improve and improve the current Chinese led fluorescent tube not only to improve the light efficiency, prolong the service life, maintenance and repair rate, its cost of production prices continue to decline, led fluorescent tubes into the civilian market area will be earlier than the market expected time.

China LED fluorescent Tube development process according to the LED light source, heat dissipation shell material or design different, power to place different ways. According to the different LED light source China led fluorescent tube development process sequence is roughly lamp series, SMD series and COB package type three kinds; According to the thermal shell material or design shape different development process sequence for the plastic, half-plastic, aluminum tube type, all aluminum three kinds ; Depending on the power placement method, the sequence of development process is both built-in and external; According to the different structure model, the sequence of the development process is T8, T10, T5. The following main introduction of the Chinese LED fluorescent tubes according to the use of different light source development process. Figure 1 Below is the development process of light source used by China led fluorescent tubes since 2005.

Since 2005, China led fluorescent lamp light source use changes: The main choice of light for F5 straw hat, 3528, 5050, 3020, 3014, 5630, 2835, COB package statistics, and 3535, 5730, 2020, F5 helmet, F5 flat Head and other light source due to the use of very little, not in the statistical range.

In many optoelectronic enterprises nationwide, LED fluorescent tube light source selection is also diversified, each accounted for a different proportion.

According to glii survey data in the first half of 2012, China led fluorescent tube development has been using the light source has F5 straw hat, 3528, 5050, 3020, 3014, 5630, 5730, 2020, F5 helmet, F5 flat head, 2835,, 3030, 3535, 2016, COB package series, LED fluorescent tube development period of different choice of the main source of difference. The following Figure 2 is the first half of the 2005-2012 years in China led fluorescent tubes using different light source amount of change in the description:

Other medium power: mainly refers to 2835, 3030, 3535, 5050, 5730, 2020 series.

Since 2005, China led fluorescent tubes used by the light source changes are more obvious, this is mainly with the LED industry as a whole technology and the market for LED fluorescent tube demand has a relationship between:

2008 years later, the use of F5 straw hat straight plug series do light source LED fluorescent tube accounted for a sharp reduction, by other sources of light, by the end of June 2012, F5 Straw Hat series LED fluorescent lamp tube in the market share of less than 0.5%, only some manufacturers also maintain a certain amount of production, The main reason is that its early customers or more trust in such products.

Starting from the second half of 2009, 3020 and 3014 as LED fluorescent tube light source gradually occupy 3528 and 5,050 parts of the market, the same year 5630 of the power started by a small number of enterprises in the LED fluorescent tubes, and 5050 series of light source used in LED fluorescent tube data began to decline;

In the second half of 2011, 2835, 3030, 3535, COB package as the representative of the high-power as the light source led fluorescent tube accounted for faster growth. According to GLII statistics, the current Chinese led fluorescent tubes used by the light source is still lamp direct insertion series, SMD Patch series, COB package series, but the ratio varies over time.

3528, 3020, 3014 equals Super 50%

Glii statistics show that the first half of 2012 LED fluorescent tubes of light bulbs accounted for more obvious than the same period in 2011, SMD series will still be led fluorescent tube market demand focus.

In the first half of 2012 China led fluorescent tubes used in various types of light source products accounted for the change is more obvious, including: Lamp series LED fluorescent tube number accounted for less than 0.5%, 3528, 3020, 3014 light source series LED fluorescent tube number total accounted for more than 60%, and to 2835, 3030 , 3535, COB packaging and other series for the representative of the light source LED fluorescent lamp tube number accounted for all of the biggest growth, the overall ratio reached 16%.

The obvious reason for the change of light source usage of LED fluorescent tube in China

The main reasons for the change of the number of LED fluorescent tubes are:

Lamp series is eliminated mainly with its own products exist heat dissipation, light-emitting angle small, light decay high has a direct relationship. Lamp Series products because the stent pin is small and most of the iron material, the overall heat dissipation of light source products. LED fluorescent tube For a long time to light its internal lamp series light source heat, seriously affect the life of LED fluorescent tubes and light decay. 2009 years ago, led fluorescent tubes used mainly lamp series, but in the subsequent use of lamp series has exposed the light source heat is not in time, light failure led to the short life of LED fluorescent tubes, SMD series to replace lamp series become LED fluorescent tube light source to become the best choice for customers. But because the Lamp series light source uses the glue seal to be strong, bears the fall therefore in certain application domain, still takes the lamp series light source primarily, this will maintain for some time.

3528, 3020, 3014 series total accounted for more than 50% of the main reasons are: A. 3528, 3020, 3014 series products single structure, good heat dissipation, small size, use in LED fluorescent tube without spot, and low cost. b.5050, 5630 particle size larger, the use of LED fluorescent tubes in the larger spacing, the resulting spots are too obvious, more suitable for some of the advertising series LED fluorescent tubes, lamp strips, etc., is not the best choice for LED fluorescent tube light source.

To 2835, 3030, 3535, COB package, such as the representative of the high power to become a fast way to reduce the cost of enterprises. With LED fluorescent tube prices continue to decline, LED fluorescent tube production enterprise gross profit margin is very large compression. According to GLII Research report data show 2010 years led fluorescent tube average gross profit margin reached more than 48%, but by the first half of 2012, the data dropped to 26%, or even lower. Therefore, many enterprises at present to seek to reduce the cost of light source indirect led fluorescent tube cost reduction. 2835, cob packaging products gradually become one of the main light source LED fluorescent tubes. 2835 series of 0.2W series products, so the LED fluorescent tubes in the same power to use more than half of the number will be reduced, led fluorescent tube cost reduction is more obvious; and cob package because of the overall light efficiency, good spot, low cost to become led fluorescent tube light source is another choice, and cob Packaging series in the future will be LED lighting application of one of the main light.

LED fluorescent light source in the future high-power series mainly

Lamp series of light can not be replaced mainly with the SMD series of products in the waterproof, moisture-proof measures are not perfect, with the SMD used silicone glue packaging, its waterproof, moisture has been greatly improved, but to reach the lamp series waterproof, moisture-proof degree still need a certain time, The lamp series will eventually be replaced.

At present, LED fluorescent tubes will be to the high light effect, low price, high quality, high-reliability trend development, from GLII statistics show that cob package just can achieve high light efficiency, low cost, so the next few years to 2835, 3030, 3535, COB Packaging Series for the representative of high-power series LED fluorescent tube number accounted for a rapid increase.

For some time in the future China led fluorescent tube will be formed in high-power series LED fluorescent tube, 3528, 3020, 3014 series of light Source as a supplement led fluorescent tube market.
