Crack EMC puzzle, low power efficiency is the key

For nearly two years, it seems all LED are engaged in EMC, but also to cry can be heard without end, now is not really EMC or Starving people fill the land., do it, the reason is the quality, capital, or consumer acceptance consciousness of the problem? This paper will focus on the analysis of EMC difficult to promote the cause and solution.

EMC has called for many years in China, but the domestic engineering really decent but a few, most of the EMC is also doing watching, because the recovery time is too long, are worried about the unpredictable problems in the cost recovery period. According to personal contact with the EMC for a long time, the current EMC is nothing more than the following types:

First, the pursuit of the perfect type: hope LED from illumination, brightness and color rendering index on the environment than energy-saving lamps, but also hope that the LED in five to ten years, without any damage, and that LED five years of decline within 20%, and wish to LED after the replacement, energy saving 60-70%. It is a low cost, can recover the investment in 1-2 years, who is responsible for the majority of enterprises have this mentality, most of these people from a non LED industry team, technical personnel.

Two, quanqian type: this type of enterprises listed companies or suppliers for listed companies, their attitude is as long as the product is not a big problem, the signing of the contract can be announced to the stock market on money; or the enterprise itself is not listed, choose listed companies as suppliers, which can greatly directly or indirectly low price suppliers (indirect price is 20-30% and five years after the expiration of the contract, such as supplier payment) can take the contract to the announcement, the stock market value is much higher than the profits of the products.

Three, hurry to market type: National LED lighting more than 7 thousand, but the real value of more than 200 million enterprises listed due to very little, some, but could not find a good market, slow sales, in this case, the best way is to rush to market distribution, and EMC is a relatively fast way to take advantage of the last prepare a year listed on the final struggle, can together. Of course, shop goods as receivables and bad debts, such as can not be put together, and it is possible to fight down enterprises;

Four, take allowance: some companies take advantage of state subsidies, registered energy management company to contract, low-quality products for users to change, and then take the contract to apply for subsidies to the state, there are users due to product price, can recover the cost in almost a year, also won't have too big reaction.

Five, Pinbo type: this type of customers are mostly doing market origin or do good public relations, they are not familiar with the product, but is in the most intuitive way to test, such as product light for a period of time, accounting down is cost-effective, and the supplier dare to promise five years warranty, the main financial strength of these enterprises strong or strong financing ability, they push toward EMC or larger.

Six, technology type: this type of customer long-term work in the EMC market, the energy saving scheme is extremely mature, to the user to do the program to consider energy saving and cost recovery in all aspects, such as the remote control and intelligent control system into energy-saving lighting scheme, of course, this kind of customer and manufacturers cooperate closely, and put forward the requirements for the development and production of LED manufacturers.

To sum up, no matter what type of return to the nature of EMC, or to improve the product's energy, improve product quality and reduce product cost, this is the three premise of the benign development of the EMC, according to my long service EMC experience, the amount of energy is the most important issue, the development of EMC in:

Lamps currently on the market with the most important of the three, namely three color tube, halogen powder tube and T5 tube, as below. Three kinds of light to do the following analysis:

1,: this kind of pipe tube halogen powder is not high brightness, luminous flux of about 1400-1500LM, according to the current market better LED 90LM/W products, but also need to be 16W, but I do not know, most of the fluorescent lamp and no 40 watts of imagination, but 32-34 watts, according to average is 33 watts if the day lighting 12 hours, electricity 0.9 yuan / kWh: (33-16) *12*365*0.9/1000=67 yuan, if you count into to the user, then two years barely recover costs.
