LED luminous efficiency hits a new high
For the current stage of LED manufacturers in various countries to improve the efficiency of light extraction. In the laboratory, if the power is high, the chip size is 1 square millimeter, and the input current is 350 milliamperes, the current US company Cree is the most proud. The company was announced in early December 2009. The luminous efficiency of white LEDs has reached 186 lumens per watt, while the commercial products began to provide customers with a total luminous flux of 139 lumens and a luminous efficiency of 132 lumens per watt in the third quarter of 2009.
As for Nichia's Photonis West exhibition in February 2009, it announced that it has successfully developed the industry's highest luminous flux of low-power white LED chips. The white LEDs released by Nichia have a luminous efficiency of 249 lumens per watt at 20 mA, which is the highest in the industry. Nichia has maintained its leading position in the development of low-power LEDs. In December 2006, the company achieved luminous efficiency of 150 lumens per watt. In September 2007, it reached 169 lumens per watt, and now reaches watts per watt. 249 lumens.
Compared with other traditional light source technologies, the progress of LED technology has become more and more mature. There is still room for improvement in LED luminous efficiency. If the technical development of various manufacturers at the current stage is analyzed, although in 2009, only the company can provide 132 lumens per watt, but According to the US Energy Agency (DOE) forecast (Figure 3), the LED single-element luminous efficiency has an opportunity to increase to 188 lumens per watt in 2015, and the warm-light part also has the opportunity to achieve 138 lumens per watt, if the overall lighting efficiency of the luminaire is added In view of this, the opportunity for LEDs to become general lighting has increased considerably.
LED prices will fall rapidly
In addition, from the perspective of lighting cost, compared with fluorescent lamps, power-saving lamps, incandescent bulbs and high-intensity gas discharge (HID), the unit cost of the conventional lamp source has no room to fall compared to the LED lamp, and the LED light source is between 4,100~ The cost estimate of 6,500K can be reduced by more than 90% from $25 per thousand lumens in 2009, reaching a water level of $2 per thousand lumens.
Take the US lighting market as an example. According to the general public's perception, the new light source should be cut into the general lighting market at a cost of at least $5 per thousand lumens, so it is relatively competitive. Therefore, between 2012 and 2013, LED lighting is cost-effective. Will be comparable to traditional light sources. If the LED luminous efficiency can be estimated by the US Energy Bureau, by 2015, LEDs will only have 2 US dollars per thousand lumens, and the opportunity to cut into different lighting places is bound to increase.
Since the development of LED lighting, manufacturers have introduced LEDs with luminous efficiency of more than 130 lumens per watt. If the current average luminaire efficiency is estimated to be 50-70%, the total efficiency of LED lighting fixtures will be at least 65 lumens per watt. For accent lighting, or replacement of disabled incandescent lamps, they are already qualified to enter the market.
For the indirect lighting or the final main lighting market, in addition to the LED technology must be upgraded, the price drop, the improvement of the lighting efficiency and the advantages of the traditional light source are all issues that LED lighting must face in the future.
According to the analysis of the Optoelectronics Association (PIDA), LEDs will play the role of local lighting or key lighting at this stage. It is estimated that LEDs will have the opportunity to cut into indirect lighting in 2012, but if LED TV can be accepted by the market in the past 1-2 years, The price of LED components will increase rapidly as the scale of the industrial economy expands. The time course for the main lighting source is expected to occur in advance.
There are many LED lighting applications, and in the next few years, LEDs will quickly cut into the application market such as street lamps, commercial store lighting and residential lighting where LEDs will eventually enter.
Government to buy a single street lamp application first debut
Road lighting requirements must take into account factors such as visibility, inducement, clarity and comfort. In recent years, due to the prevalence of overall urban landscape design concepts, the damage caused by light pollution to the environment, and the importance of lighting energy conservation issues, The cause of the light source cutting into the street lamp application market.
At present, HID lamps are mainly used in the selection of road lighting sources. If the types of light sources are used, the most common ones are high-pressure nano lamps, followed by mercury lamps, and then complex metal lamps.
First of all, according to the current development of various technologies, the efficiency of high-power LEDs is no longer a problem for the street light market, but LEDs are semiconductor materials. More than 80% of the input power is converted into heat, and the luminous efficiency varies with the chip temperature. Under the rising and falling characteristics, solving the heat dissipation is still a difficult problem that LED street lamps must overcome in application.
In addition, the optical design is also a challenge that various manufacturers actively overcome. As for other LEDs that require DC drive, the arrangement and power supply selection are technical priorities, while being resistant to wind pressure, lightning strike, vibration and other safety. Considering, both increase the LED streetlight design challenge.
Based on safety considerations, street lighting has a set of specifications that must be observed. Depending on the region and road conditions, countries have different regulations on illuminance, illumination uniformity and glare. At present, these standards have been released. In addition to the US DOE's LED streetlight specifications for outdoor lighting, Taiwan also announced the first set of LED lighting standards in 2009, namely the National Standard (CNS) No. 15233 "LED Street Lighting Standards" ".
Although from the end of 2007, the market has continuously heard the news that manufacturers have received orders for LED street lights, but they have not found the best solution in terms of light, electricity, machine, heat, etc., in the case of mixed products of various manufacturers, eager to The construction of the Chinese mainland equipment completed before the Beijing Olympics in 2008, the negative news of the life and overall performance of LED street lamps was not as expected, and buyers began to have high doubts about the quality of LED street lamps, which in turn affected the willingness to purchase.
In addition, in order to promote the local LED industry, the Chinese government also offered the “Ten Cities and Ten Thousand Miles†pilot demonstration project. The scope of the promotion includes tunnel lighting, subway cars/stations, underground parking lots, and gas stations. Demonstration applications for lighting, interior lighting and other products.
However, the budget of the Ten Cities and Ten Thousand Cities Project is also from the Chinese government. According to the statement of the deputy secretary-general of China National Semiconductor Lighting Engineering R&D and Industry Alliance, the ten cities are not a commercial market expansion project. At this stage, there are still basic issues to be solved. The solution, and the source of funding for the ten cities, is scheduled to be allocated by the central government in 2010 and distributed to the demonstration local governments.
In addition, it is worth noting that since the focus of this project is to foster the LED industry in mainland China, the relative threshold for the Taiwanese industry or the LED industry in other countries to really eat this market is higher.
Due to the excessive difference in quality of LED street lamps, the lack of confidence in the market has led the industry to understand that if LED street lamps are not seeking the best solution in the light, electricity, machine, heat and other aspects, and improving the overall reliability of the products, the future market is difficult to There is competition for traditional street lamp products. It is expected that in 2010, the global LED street lights will be at least 150 million miles due to the implementation of the Chinese government's budget to promote the ten-city policy.
