The transformation of the LED lighting industry, I borrowed from the political roadmap designed by Mr. Sun Yat-sen, the military, political, constitutional and three-stage theory.
On January 29, 1923, Mr. Sun Yat-sen published a "The History of the Chinese Revolution" in the special issue of the 50th Anniversary of the "Declaration", saying: Yu's revolutionary strategy stipulates that the period of revolution is three: the first is the military and political period, the second is During the period of training, the third was the period of constitutionalism.
For the LED lighting industry, the military and political period is the primary stage of lighting brand and channel construction. It relies on the guns to go out of power. At this time, based on product warfare, it is usually necessary to establish a market position with a single product champion: the training period It refers to the moment, after the enterprise has occupied a certain market, what needs to be done at this time is to establish a system of rules. The so-called high wall, wide grain, and slow king are the key points at this time, only to establish a healthy marketing ecology. The system can only be reborn; in the final constitutional period, when more than half of the market is deep, the company can take corresponding measures and complete its mission.
At present, many LED lighting companies in the industry have gradually found a way through the first stage of exploration, and have achieved results in the initial stage of brand building and channel construction. These companies are the new force in the transformation of the entire LED industry. Lin always mentioned in a speech on the new forces that revolutionized the LED industry landscape:
2010-2020 will be the world of LED commercial lighting, home lighting. From the perspective of light efficiency development, in 2011, the efficiency of conventional LED light source is up to 135lm/W; in 2012, the luminous efficiency will reach 148lm/W, and by 2015 it will reach 200lm/W. From the perspective of cost performance, in 2008, DipLED per 1000 Lumens need to spend 500 yuan; in 2011, SMDLED costs 83.3 yuan per 1000 lumens; in 2013, only 33.3 yuan per 1000 lumens, LED lighting products cost-effective year by year, in just 5 years, the price/performance ratio has increased 15 times. LED lighting penetration rate was only 8.5 in 2010, and is expected to reach 38.4 in 2015, a five-fold increase.
Collaboration and industry advancement will be an important trend in LED development. With the continuous development of LED technology, the market competition is becoming more and more fierce, and the high cost performance of products has become a sword for market development. LED heavyweight enterprises have mastered the important weight of developing the market because of their important technology, large-scale production strength and abundant funds. Lin Jiliang boldly predicted that compared with the past, in the era of LED lighting, standardized light source manufacturers will be more concentrated.
LEDs bring great imagination to the luminaires. LEDs can be realized without the traditional luminaires. Many people always like to rely on many places, and feel safe, but in fact, the more people there are, the more intense the competition, the lighting market is like this.
For downstream applications, the opportunities for LED manufacturers and SMEs coexist. It is recommended that SMEs should consider moving to the LED lighting segment. For the standardized light source market, it is more and more difficult for SMEs to compete with big manufacturers. SMEs should go to specialize in a certain field and become the leader in this segment, so that they have their own integration in the future integration tide and price war. Living space.
How to achieve success in channel construction and the common growth of agents is indispensable. Only when the product quality is guaranteed and the price is competitive, the manufacturer can really bring benefits to the agent and become a community of interest in long-term cooperation. After establishing such a benign relationship, the loyalty of the agent and the support for the manufacturer will be gradually improved, and the channel of the manufacturer's channel construction will naturally become more and more smooth.
Led street light, compared with the traditional lighting technology, led lamps and lanterns have higher efficiency, and longer service life.Thus become the preferred bulb type, in order to reduce the energy consumption of indoor/outdoor lighting, get energy saving effect.
For street lamps, higher efficiency and longer life are indispensable for cost reduction.Designed for the LED power supply switch power supply, also must have a high efficiency and durability, to ensure that it has as long as the LED life without maintenance.Here, the resonant converter is one of the most popular power supply topology, this is because compared with previous power supply topology, their performance has brought higher power efficiency, and can reduce EMI.Soft switch is an important characteristic of resonant converter.But the resonant converter used in parasitic diodes (bodydiode) can sometimes lead to system failure.Stored in the parasitic diodes charge must be clear, to avoid large current and voltage surge, including topology structure of high dv/dt and di/dt.
