General lighting requires lamps with high luminous efficiency, long life and environmental protection. The main difference lies in the lighting effect and quality of indoor lighting sources (including color rendering, chromaticity consistency, light source output and uniformity, human eye comfort). Sex, etc.) have higher requirements, and the consumer groups they face are more sensitive to the price of lamps. On the other hand, the advantages of the luminous efficiency of the blue chip need to be further improved and limited by the packaging technology of the white LED. Most of the current semiconductor lighting fixtures are high color temperature and cool white light, and the consistency of the color product is not as good as that of the conventional lighting. The intention is that semiconductor lighting fixtures are currently in large-scale applications in outdoor lighting, and have just begun to take off in indoor lighting. Therefore, limited by cost and lighting quality, semiconductor lighting will be the first to be applied in large-scale outdoor lighting, and then gradually enter the field of indoor lighting with the continuous development of technology.
The most commonly used products for indoor lighting are incandescent and fluorescent lamps. Incandescent lamps have extremely low luminous efficiency, only a few lumens per watt, while fluorescent lamps contain harmful substances such as mercury, which is not conducive to environmental protection. Therefore, indoor lighting has a stronger demand for efficient and environmentally friendly lighting products. Although the current white LED devices have surpassed incandescent lamps and fluorescent lamps in terms of luminous efficiency and environmental protection, the lighting effects and quality of the lamps formed by them have not rapidly formed the advantages of traditional illumination sources, and their applications in indoor lighting. just began.
"In terms of the product characteristics of LEDs, the most suitable place for application is indoor lighting." This is the view of many companies. Relative to outdoor road lighting needs to face the challenges and challenges of many natural worlds. LEDs are used indoors, have better stability and reliability, and the difficulty coefficient is greatly reduced, and the development speed will be faster. Insiders said that LED has a larger space for indoor lighting development and is more suitable for the characteristics of the product itself. It is expected that with the price reduction, technological advancement and product maturity, LED is expected to enter the room in a large scale within 3 years. General lighting field.
Indeed, in terms of product characteristics, LEDs have many advantages for indoor lighting. First of all, the brightness and color of the LED are adjustable, which can perfectly satisfy the color atmosphere of the interior decoration. In the development of the scene lighting market, it has the advantage that the traditional light source is incomparable. Secondly, the LED is easy to dynamically control, and the cluster control can be designed according to the user's needs. In some occasions requiring programming capability, a series of solutions can be provided to provide convenient operation for intelligent management of indoor lighting. Thirdly, the LED is compact and more decorative. Through the design of the luminaire, it can be integrated with the building to achieve the effect of seeing no light. Fourth, LEDs have long life and no mercury, which is in line with the national policy of “energy saving and emission reductionâ€. Of course, you can also list the fifth, sixth... more advantages. Although the lighting products of large public buildings and office spaces are mostly based on T12 straight tube fluorescent lamps and grid lights. In commercial places such as hotels, shopping malls, supermarkets, etc., lighting products are mainly T10 or T8 straight tube fluorescent lamps, incandescent lamps, grid lamps, halogen lamps. However, with the improvement of LED technology, the emergence of energy-saving effects, and the decline of cost, LED has begun to enter indoor commercial lighting and even some household lighting markets in both the international market and the domestic market, showing a good momentum of development.
According to statistics, as of February 2009, the domestic market has installed and used more than 200,000 LED indoor lighting fixtures, and estimated that the total amount of 2009 will reach 300,000 baht. It is expected that in the next 3-5 years, LEDs will be decorated from high-end homes. Lighting to functional indoor lighting has been gradually applied, indoor lighting will become the main battlefield of LED lighting in the future.
