Last year, the LED lighting market gradually recovered and orders increased significantly. With the growth of LED, the future development of the lighting industry has become clearer, and the old lamp companies have also accelerated the pace of transformation. At the beginning of last year, NVC Lighting, which ended the fight, quickly overwhelmed the LED market and proposed to exceed the annual sales target of RMB 1 billion last year. Currently, NVC Lighting's revenue from sales of LED products has increased to 16.7% of its total revenue. According to its financial report, during the first six months of last year, NVC Lighting's total sales of LED products reached 280 million yuan, an increase of 233.9% compared with the same period of last year. The growth rate is even more pronounced in the second half of the year, and it is more optimistic to complete the sales target of one billion yuan.
Similarly, Foshan Lighting Co., Ltd., which has experienced investor complaints and high-level shocks, has not relaxed its LED layout and has continuously launched low-priced products to hit the market. Reporter in the Lynx Mall inquiries, a business agent of Foshan Lighting 3W LED bulb lamp single price has been refreshed to 9 yuan, 2W bulb light does not post it dropped to 5 yuan.
“For traditional lighting companies, their attitude toward LED lighting is more contradictory.†Lan Wenliang, Marketing Director of Xianglong Electronics, reminded. From the time point of view, traditional lighting giants do not want LED growth too fast, because their traditional energy-saving products must exit in an orderly manner, including equipment and other updates, must have a certain amount of time, which is also caused by traditional lighting giants The reasons why the LED business had been reluctant to send force before.
In addition, subject to the impact of brand image and policy inertia, traditional lighting companies are particularly cautious about the reliability of LED products and the formulation of market strategies, causing them to fail to respond quickly in the LED field. The earlier idea of ​​traditional lighting companies was to hope that LED's development slowed down, so that they have enough adjustment and turn around time.
However, judging from the current situation, traditional lighting companies do not have much buffer time in LED business and must respond in a timely manner. Therefore, we can see that NVC lighting, Foshan Lighting, Sanxiong, Aurora and other old lamp companies have recently invested heavily in LED business.
The “awakening†of traditional lighting giants on the LED battlefield indicates that the LED lighting market is growing rapidly and its maturity is increasing. On the one hand, it also adds a lot of variables to the competition in the LED market. Traditionally, as the enterprise enters the LED field on a large scale, it naturally inevitably affects the emerging LED companies, and the market war between the two parties is imminent.
There are two types of noise canceling headphones, active noise reduction and passive noise reduction.
The active noise reduction function is to generate a reverse sound wave equal to the external noise through the noise reduction system, and neutralize the noise, thereby achieving the effect of noise reduction. Active noise canceling headphones with noise-reducing circuits that compete with external noise. Most of them use a large head-mounted design, which can be used to block external noise by using earplugs and earphone casings, and to perform the first round of sound insulation. There is plenty of room to install active noise reduction circuits and power supplies.
Passive noise canceling headphones mainly form an enclosed space by surrounding the ear, or use soundproof materials such as silicone earplugs to block external noise. Since the noise is not processed by the noise reduction circuit chip, generally only high frequency noise is blocked, and the noise reduction effect on the low frequency noise is not obvious.
Application:
1: Business people, because of frequent business trips, especially those who travel between different cities every day, they must hate the noise in the cabin. If there is a noise-cancelling earphone, they will be able to stay away from these noises. Relax by enjoying the music.
2: The office staff also need a pair of noise canceling headphones. Sometimes when thinking about planning, listening to the sound of central air conditioning is particularly annoying, and if there are colleagues around at this time, it is even more annoying. At this time, you may wear a pair of noise-cancelling headphones to expand your thinking in music.
