At present, in the LED lighting market, outdoor lighting and public lighting are the best to replace traditional lighting with LED lighting. Home lighting and commercial lighting are gradually replacing the road. Office lighting can be said to be successful late. fortress.
◠T5 fluorescent tube in the appeal of energy-saving office lighting is the strong reason for the office's existing lighting, generally at home and abroad, is based on T5 fluorescent tube, the luminous efficiency of this tube is as high as 90lm / w ~ 100lm /w, the price is low; in Taiwan, the general company does not save electricity. It uses T8/T9 traditional fluorescent tube of this specification. It is relatively thick, and the luminous efficiency is only 50lm/W~65lm/W. It can be LED light. It’s true that the tube is replaced, but the price gap is even bigger. T5 fluorescent tube is relatively thin, in addition to the high luminous efficiency, the product life is 6,000 to 10,000 hours, relatively short, so it is widely loved by the emerging office lighting market, as well as energy-saving enterprises, applications There is also a large proportion in the field of office lighting. For example, the price difference between a T5 fluorescent lamp and a T8 LED is between about 1.5 and 2.5 times. Vendors must consider the difference in service life, the difference in energy efficiency, and the difference in return.
â— Power system and office building contract Another office lighting will lead to the late LED lighting tube, which is the problem of the power system. In the case of cost, the existing grille light is replaced by the LED light tube. Power modification is also a small project.
Then there is the existing office building market, which is mainly rented by the landlord to the company. The willingness to take the initiative to replace the lighting system is even lower. The lease includes hydropower. If it is not included, the willingness to replace the LED lighting will be poor. In addition, whether the contract can modify the lamps and replace the lamp system, these have a lot of eyebrows in the European and American markets.
Office LED lighting is actually more diverse than imagined, reception areas, corridors and passage areas, open large offices, cubicle conference rooms all the way to the building's exterior walls and parking lots, are considered part of the office lighting.
The main lighting for replacing the overall space of the office, although the level is level, can be used from small places like office signs, counter lamp lighting, reception room recessed lights, indoor small lamps, etc., except that it can be included without the power system and rent. In addition to the cost limit, it can also enhance consumers' willingness to spend and the first impression and overall space design.
â— Price, product maturity and return time LED lighting has difficulty in price in any market, but in the parking lighting in office lighting, there are also examples of saving blood and LED lights to save more electricity. For example, if the office is switched to LED lighting, the use of LED tubes is a cheaper way to replace the grid lights, but if the flat panel lights with better light uniformity are also very good, the cost difference, individual companies, offices Buildings need to be evaluated and absorbed.
The cost of full replacement is amazing, which is why LED lighting has not been popularized in the field of office lighting. To replace it with LED lighting, the cost is two to three times that of traditional light sources, plus the power supply and the aforementioned lease problem. Reduce consumer willingness. However, if the LED lamps are well matched, the energy-saving efficiency is high, and the time to pay back can be long or short, and can be completed in 2 to 3 years. But if your office lighting already uses T5 fluorescent tubes, then replacing them with LED lights for office lighting will take longer.
It is gratifying that the proportion of LED tubes and LED panel lamps is increasing in the new office building market, and there is still a way to go before the office space is replaced.
