TLT pointed out that the LED series bulbs sold this time have an outer diameter of 60mm and a total length of 109mm. They are the same size as the mainstream bulbs on the market and can be directly replaced with a weight of 140g; the 6.9W bulb is equivalent to a 60W incandescent bulb, while 4.1W The brightness of the product is also close to the brightness of a 40W general bulb. Toshiba said that the product has a life expectancy of 40 times that of a typical bulb and about 40,000 hours. As for the average color rendering index (Ra), the warm yellow bulb is CRI80 and the white bulb is CRI 70.
In terms of selling price, the price of 6.9W is 5,460 yen (about 769 yuan), and the price of 4.1W is 5,250 yen (about 739 yuan). Compared with the 4.3W LED bulb that TLT sold 15,000 yen on March 18, the price has been greatly increased. Reduced to less than half.
TLT further stated that the 2009 E-CORE series 6.9W and 4.1W total sales target of 500,000; in 2009, Q3 will also be scheduled to launch higher power (about 1.4 times existing) and dimming Features a 6.9W LED bulb to expand its product line.

CWDM - Coarse Wavelength Division Multiplex
CCWDM is Compact CWDM (Compact Coarse Wavelength Division Multiplexing), a wavelength division multiplexing technology based on TFF (Thin Film Filter). It works in the same way as CWDM modules, except that CCWDM uses free space technology. , compared with the common CWDM optical fiber cascading method , the CCWDM package size is greatly reduced compared with CWDM modules, and the insertion loss is lower and the consistency is better; it can replace CWDM Products are used in telecommunications, enterprise networks, PON networks, cable television and other fields. The lower insertion loss enables the CCWDM module to have lower signal attenuation during use, thereby reducing the power requirements of the signal transmitter.
For the CWDM module, limited by the minimum bending radius of the optical fiber line, the size of the packaging box cannot be made too small, resulting in most of the space in the box being idle. The adjacent channels of CCWDM use parallel beams to cascade in free space instead of optical fibers. Without the optical fiber used for cascading, the size of the CCWDM packaging box can be greatly reduced. For example, the size of the common standard 4CH CWDM is 80×60×12 mm, and the size of the CCWDM module of Yiyuantong is 50×27×7.7mm, which is only 1/4 of the standard CWDM package size. Can be widely used in high-density environments.
