LED lamp and fluorescent light competition for the former slightly immature technology

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 has been 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, office workers were concerned about eye fatigue and seeing afterimages. The 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.

Japanese companies already have Panasonic said that because the company's LED tubes 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.

Before the United States DOE and the Japan Electric Ball Industry Association conducted a comparative survey of LED tubes and fluorescent tubes, they all showed that LED tubes were not enough to completely replace fluorescent tubes. LED lamps consume less than half the power of fluorescent tubes, but their brightness is only within half, causing some office users to express dissatisfaction.

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

On the other hand, the Japan Electric Ball Industry Association has organized guidelines for the correct use of LED lighting, and the Japan Lighting Industry Association has also sorted out brochures on the use of attention and hopes to reduce problems that may occur in the practical application of LED lighting.
