SMD: It is an abbreviation of Surface Mounted Devices. It is one of Surface Mount Technology (SMT) components. In the initial stage of circuit board production, through - hole assembly is completely manual. When the first automated machines were introduced, they could place some simple pin elements, but complex elements still needed to be placed manually for reflow soldering. Surface Mounted components mainly include rectangular chip components, cylindrical chip components, composite chip components and special-shaped chip components Surface Mounted Devices Changzhou Changyuan Electronic Co., Ltd. , https://www.cydiode.com
â—T5 fluorescent tube is in a strong position to appeal to energy-saving office lighting
The reason is that the existing lighting in the office, generally at home and abroad, is mainly based on T5 fluorescent tubes. The luminous efficiency of such lamps is as high as 90lm/w~100lm/w, and the price is low; Electricity, the traditional fluorescent tube with T8/T9 specification is relatively thick, the luminous efficiency is only 50lm/W~65lm/W, it can be replaced by LED tube, but the price difference 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 T5 fluorescent lamps and T8 LED lamps is between 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 reason why the office lighting will lead to the LED tube will be late. It is a problem in the power system. In the case of cost, it is necessary to replace the existing grid lamp as an LED tube. The external power supply required is also a minor 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 lot lighting in office lighting, there are also examples of saving blood and replacing 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.

Why did LED lighting delay the break of office lighting "fortress"?
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.
