CITIZEN electronics developed the maximum luminous flux reaches 10 thousand 7675lm super bright white LED lighting, and will start mass production delivery. According to the company, the flux will be increased to about 4 times the original product, the luminous flux obtained by a package for the world's largest. The value is the average color rendering index (Ra) is 65, the color temperature of 5000K products obtained by the brightness value, while Ra is 80, the color temperature is 3000K and it is difficult to improve the brightness of the product can also get a luminous flux of 10 thousand 4290lm.
The product is designed to replace the input power of 300W mercury lamp. Prior to the use of a number of white LED to get a higher brightness, and the product is only one LED can be said that the luminous flux reached a new height of white LED brightness. "Even before further increase in luminous flux, it can not meet the needs of the replacement of existing light sources" (CITIZEN electronics).
CITIZEN released the white LED not only has a high luminous flux, product line is also very characteristic. A variety of products covered by a wide range of luminous flux, although the flux range overlap, but a variety of products covering the range of 95 ~ 10 thousand 7675lm brightness (Figure 1). For example, in the case of Ra 65 4000lm luminous flux, there are 5 kinds of products to choose from, and can choose the package size of the 3.
Figure 1: product line is complete
From the CITIZEN electronics lighting with white LED new product line, covering a wide range of 95 ~ 10 thousand 7675lm luminous flux range, and a variety of products have overlapping coverage of luminous flux. Users can choose different products according to the requirements of efficiency, miniaturization and low cost.
At first glance it seems wasteful. However, CITIZEN said it is very important to do so: the requirements of a variety of lighting manufacturers, including miniaturization, high efficiency, low cost, as well as the design of heat dissipation components, etc.. This product line can meet these requirements". For example, if the preferred luminous efficiency, you can choose the large size products can support large flux, reduce the current when in use; and give priority to the cost of the case, the small size of the product, the current increase in the allowable range to obtain brightness; also can choose white LED based on the performance and cooling capacity of cooling components the lighting installation.
At present, the manufacture of high-power lighting products manufacturers are increasing. CITIZEN electronics by virtue of the customer's point of view to build product lines in order to win in the competition. In the future, the white LED luminous flux will reach the limit, the focus of competition in the field will shift from brightness to meet the specific requirements of customers.
