A few days ago, Japanese lighting experts came out with a speech at the Taipei International Convention Center, "The latest trends in LEDs and the development trend of Japan's standardization". The LED luminous efficiency is 7-8 times that of incandescent lamps. In addition, Japan completely banned incandescents in 2012. Lights, once LED lighting is popular, will reduce 3.4 million tons of carbon dioxide per year, which will undoubtedly add a boost to the Kyoto Protocol's carbon emissions reduction.
LED luminous efficiency will reach 150lm/W in 2015, and the price of lamps will drop by more than 30%.
According to Mr. Chengfu, in the market structure of Japanese lighting fixtures in 2020, the proportion of LED lighting in the Japanese lighting market will increase from 0.8% in 2008 to 8% in 2015 to 25% in 2020. . In addition, HF inverter fluorescent lamps are still maintaining their advantages from 40% in 2008 to 70% in 2020;
Magnetic gas fluorescent lamps that originally had a large market share will not be used after 2020. The main reason is that LED luminous efficiency is expected to increase by 150 lm/W in 2015, which is much larger than that of fluorescent lamps. Under this development, in 2015, the price of LED lighting fixtures was also reduced by one-third compared with 2009. It is more acceptable to consumers. Under various conditions, Japan can also achieve the goal of reducing carbon emissions by 20% in 2020.
Therefore, regardless of the short-term or medium- and long-term goals, the government will take into account the development of LED technology. In addition to short-term incentives such as environmental protection points for household appliances to attract consumers to buy environmentally-friendly and energy-saving products, in addition to the research and development of LED technology, it will promote the international standardization of LED lighting. . For example, in May 2010, Japan re-established the Electrical Appliances Safety Law to clearly define the power supply, voltage, and fixed frequency of electronic illuminators (LEDs, OLED lighting fixtures). The relevant official provisions are scheduled to be released before Q1 2011 and will be implemented as soon as July 2011. However, for LED lighting fixtures, the current specification object only includes electric spherical illumination, that is to say, the lamp type illumination is outside the specification object. It is expected that the characteristics of lamp-type lighting and LED-specific long-life performance will be added to this specification in the future.
Taking the electric spherical LED lighting specification as an example, LED lighting is a non-specific electrical appliance, but the DC power supply device is a specific electrical appliance, and the PSE mark should be listed on the product. Products belonging to the specific electrical appliance catalogue must enter the Japanese market and must be certified by the Ministry of Economy, Trade and Industry's authorized third-party certification body, and have a diamond-shaped PSE mark on the label. Instead of specific electrical appliances, the company expresses the round PSE mark by means of a self-declared expression in accordance with the requirements of the Japanese Electrical Appliances Safety Law.
The LED government lighting is not included in the standard, and the Japanese government hopes that the industry will constrain itself.
Although the current electrical appliance safety law does not include lamp-type LED lighting, the Japanese government still hopes that enterprises can self-discipline according to performance and safety, and form an "industry specification" that is not specified in the text. Anything that requires less than 500 grams of weight, insulation distance, etc., is expected to be the link of industry specifications. In addition, there are many precautions for the renovation of lighting fixtures, including the modification of the appliance and the transfer of responsibility and responsibility; and the guide light, emergency lighting and explosion-proof lights are not included in the list of retrofittables. At the same time, the Japanese government also requires that power stabilizers and wires should be replaced at regular intervals.
Global climate warming has become one of the world's most concerned issues, and the reduction of carbon emissions or the reduction of electricity consumption has also become a goal that countries are striving to achieve. Household appliances that are energy-saving and carbon-reducing have also begun to be favored by consumers. Countries have begun to set specifications for LED lighting equipment, and will also light up the future development of LED lighting manufacturers.
The 60W Macbook Charger with MagSafe1 or Magsafe 2 Power Adapter has a magnetic DC connector, so if someone trips on it, the power cord disconnects harmlessly, keeping your MacBook Air safe. It also helps prevent the cable from fraying or weakening over time. Additionally, the magnetic DC helps guide the plug into the system for a quick and safe connection.
