subject: Higher Interest On The Particular Led Color Rendering Index (cri) In Led Light Bulbs [print this page]


In today's competitive situation in all aspects of lighting, CRI has been capturing more and more popularity from the public. Specifically the in-door environment, which has high interest in the LED color rendering (CRI). Similar to low pressure sodium lamp which is certainly close to 200lm/W in luminous efficiency, but monochromatic yellow light was only meant for road lighting and the very few other situations. The United States Department of Energy (DOE) put to use for indoor lighting LED lights color rendering index from the first 70 (Aug.2007) for up to the present provision of practically 80 (Dec.2009).

Choice in light quality, excellent luminous efficiency and also high color rendering are the main elements for LED. The Shanghai Lighting Association chairman believes that white color is the result of high photosynthetic efficiency, extreme color rendering index and meeting the requirements of lighting environment as well as lighting operation, that is the very best white color. Endless disputes that traditional source of light and LED replacement lighting boost competition and well defined Force issues, Director also has its own unique perspective. He considers, at present condition, LED increased light efficiency signifies the emission performance is more than the traditional light source.

The standard light sources are generally in the main role in various occasions, and if we want to match up with them, we can put the High luminous efficiency regular light source put in shield as gauge, then put the led in the shield to compare, that is the favorable way. DOE current document, shows there will be common light bulbs and fluorescent lamps MR16 assessment. As for CRI, for a variety of different conditions, the color rendering index is made available to a human value but is not provided on certain occasions, for instance outdoor lighting. Some had made the extensive decision, there are so much call for the indoor lighting, such as home environment, CRI is much more than 80, it have become popular at present.

LED coming into lighting sector tends to clear, the goods of high luminous efficiency. The good color rendering index has presented its usefulness in the indoor lighting business. It showed a very good performance and strong progress. Therefore, when looking to LED light effect, we must be concerned about the color rendering index To talk about luminous efficiency, with out the value of CRI is not at all of any importance.
