LED lamp technology is immature and it is difficult to compete with fluorescent lamps

The LED light bar designed for office lighting is in a similar T8/T9, T5 size lamp tube, put into the long LED module, plus the power supply, the power is divided into two kinds of external and internal. In Sapporo City, Hokkaido, Japan, it was reported recently that in the spring of 2010, the city’s government building replaced the original 9,000 fluorescent tubes with led strips. However, after installation, the office staff suffered from eye fatigue and afterglow. A related report appears.

According to a survey conducted by the Japanese side, there are three manufacturers in the lamp replacement project, two are overseas manufacturers and one is a Japanese manufacturer, and 2,500 LED lamps from a foreign manufacturer are not used to make the light source uniform. The line so that users are not satisfied with the phenomenon. This long LED tube is a product that is not subject to the implementation of the Electrical Appliance Safety Law in Japan, and there is no corresponding JIS standard.

Panasonic has said that Japanese companies have said that because the company's LED lamps are difficult to compare with omnidirectional fluorescent tubes, the relevant product standards are not complete, so there is no need to create such LED tubes. In addition, Sharp also expressed similar views.

At this stage, Japan's LED Lighting Promotion Conference will not be able to grasp the actual number of LED product distributors on the market that actually obtain products from manufacturers in South Korea, China, and Taiwan.

The results of comparative investigations of LED lamps and fluorescent lamps before the DOE of the United States and the Japan Electric Ball Industry Association respectively show that LED lamps are not enough to completely replace fluorescent tubes. LED lamps consume less than half the power of fluorescent tubes, but their brightness is only less than half. This has caused some office users to express their dissatisfaction.

Previously, we also mentioned that LED tubes made from LED light bars cannot compete with T5 fluorescent tubes with good luminous efficiency. There are still some opportunities to compete with T8/T9 lamps. However, manufacturers must spend a lot of time on them. .
