Solid state lighting challenges traditional lighting still need to accommodate existing architecture

Although used for lighting, but solid-state lighting architecture and traditional lighting still have significant differences from optical properties to the power, and the existing lighting schema cannot be directly compatible, but a short period of time, still need to be compatible with the existing solid state lighting lighting structure.

The application can be divided into general household lighting and outdoor lighting in two kinds of high brightness LED, both the nature of the difference is more obvious in is the lumen and the driving voltage, but also because these differences make two industrial similarities and differences. Outdoor lighting required brightness and environment is more stringent, so that the outdoor lighting industry not easy to cut; but due to the lower threshold of indoor lighting, indoor lighting in many emerging firms to bet, into the LED lighting industry. However, for the LED industry, not a set of unified standards and norms, the market makes the product quality is uneven, the price and the quality gap is quite obvious, and these differences will determine the future of the company is key to solid-state lighting based on supply chain.

Solid state lighting is the trend of energy saving and environmental protection

Including the LED solid-state lighting characteristics: 1, service life: the life of LED over all other light sources, the normal Home Furnishing environment as an example, LED can be used for up to 20 years; 2, the cost of energy: LED low energy consumption, LED components such as OSRAM Opto Semiconductors GoldenDRAGONPlus luminous efficiency has reached 110lm/W. LED lights just about 6W can produce light equivalent to 25W incandescent lamp; 3, dimming function: LED can be dimmed, further reducing energy consumption; 4, no mercury: LED does not contain mercury or lead, reduce disposal cost; 5, efficiency: efficiency of LED today has about 5 higher than incandescent lamp times, along with the science and technology progress, the future will be 10 times higher efficiency. In theory, LED technology can save more than half of the electricity consumed by artificial lighting.

From a macro point of view, to promote the growth of solid state lighting power / change three. The first power comes from the government, climate and environmental protection, the government is no longer talk about, but the need to save energy is no longer just a slogan, but the policy can be achieved. Compared to incandescent lamps and other traditional lighting, LED is the first choice for low energy consumption. For example, the South Korean government's "LED bright 1530" plan in 2015 will be LED lamp market share increased to 30%, in order to save more energy. Japan's Kyoto Protocol plans to replace 8.8% of the fluorescent lamp and incandescent lamp by LED in 2012, so that it will be able to reduce emissions of up to 3 million 400 thousand tons of carbon dioxide (). Ireland and Australia were announced since the beginning of 2009 and 2010, banned the sale of incandescent bulbs; the U.S. Department of energy in September 2008 since the implementation of the LED's Energy Star label program, the Obama government allocated a budget of $80 billion for the environmental protection plan. Last but not least is China government since 2000, has been for solid state lighting plans inject more than $17 million.

Solid state lighting is more flexible than traditional lighting applications

The second driving force comes from different applications. At present, LED is mainly used in construction, outdoor advertising and portable electronic products, which accounted for the overall architectural lighting LED market 50%, such as the appearance of the building lighting, projection light wall, ceiling floodlight, indirect lighting and landscape lighting. However, the potential market for other applications is LED, such as retail display (including window lighting, retail and frozen Gui Zhaoming), home lighting (including decorative lighting, cabinet lights, chandeliers and reading lamps) and outdoor lighting (including parking lot, pedestrian areas, street lighting and public lighting). Due to the small size of the LED, so that designers have more room for the design of new lighting products, and LED applications will naturally be more extensive. And the third push comes from technology itself. LED has been proved to be the most efficient light source on the surface of the city, 5 times higher than incandescent lamp power, lumens per watt will gradually increase.

Experts believe that, according to the application of the field, LED there are two main trends: 1, the size of LED is getting smaller and smaller; 2, the scope of the application of large power LED is becoming wider and wider. The development of a number of companies with these two trends, such as OSRAM Opto Semiconductors ultra white OSLONSSLLED, packaging size is only 3x3mm, luminous efficiency leading industry, the efficiency of the general value of up to 100lm/W. In addition, it can also generate high efficiency at high current beam, thermal management, and a simplified high reliability and a 80 degree angle, it can be suitable for various applications including high efficiency, spotlights, ceiling lamps and floodlights etc.. In addition, also designed for street and developed the GoldenDRAGONOvalPlusLED, the LED does not need to prepare for the auxiliary optical devices, integrated lenses, directional light radiation pattern issued as ellipse, so most suitable for street lighting use. At the same time, the LED can produce elliptical beam special (80 degrees, 120 degrees vertical level, and the integration of the silicone lens, durable can meet the requirements of energy-saving lamps in the lighting and light pollution at least special needs, the need to let the light in accurately projecting lighting areas, not to stray light.

The power supply structure will be another wave of solid-state lighting

Now commonly used in fluorescent lamps of the architecture, and to provide the instantaneous pressure relay to the light tube, the safety risk of electric shock, but LED not be momentary high current to start, however, solid-state lighting market trend is still to replace the lighting, in addition to the challenge of ACtoDC, in order to use the existing fluorescent lamp structure, the instantaneous pressure it needs to filter the relay in the circuit,
