According to the Guangzhou Municipal Administration of Industry and Commerce, the Guangzhou Quality Supervision and Inspection Institute was recently commissioned to conduct a sample inspection of the quality of 30 LED bulbs sold by 18 companies in the circulation field of Guangzhou. After inspection, 15 samples were inspected. No unqualified, 15 samples were judged as supervised overall unqualified, the failure rate was 50. Among them, MLSLED bulb (warm white), Shangjin LED bulb (energy-saving 6W), Sori 2U electronic energy saving Brand products such as daisy series (super bright) and products produced by famous manufacturers such as Ouida Technology, Resno Lighting, Jindian Lighting Appliance Factory are on the list. This result has surprised consumers.
It is understood that the LED bulb sampling unqualified items are mainly concentrated in the rated voltage, rated frequency, use restrictions and other signs are not clear, the identification information is incomplete, easy to cause safety hazards in installation and use. In addition, there are 7 kinds of bulbs that do not meet the insulation resistance and dielectric strength after moisture treatment, and break down in the dielectric strength test, probably due to the use of poor quality insulation materials, for the lives of consumers and Property poses a security threat.
Big brand LED bulbs are expensive. The qualification rate of LED bulbs is so low. Some industry experts believe that there are many LED market companies, and there may be thousands of brands, but there are not many brands that are truly trustworthy. Products with a market price below 30 yuan are basically unreliable.
Is the market fact really the case? The reporter visited a number of building materials markets such as Bai'anju, Handan Home, and Mahui Home in Guangzhou. The concept of LED bulbs is new, the shape is high, and the price is high. In the Baihai store of Bai'anju Guangzhou, unlike the spiral of energy-saving lamps, LED bulbs are similar in shape to traditional incandescent bulbs, and the lamp heads are similar to spirals of incandescent lamps, but the shape of the products is more beautiful and simple. The LED bulbs sold here are mostly foreign brands such as Philips and Osram. Among them, Philips 9-watt LED bulbs cost 74 yuan, and OSRAM 9-watt LED bulbs sell for 49 yuan. According to Ms. Cai, a shopping guide in the lighting area of ​​Bai'anju Haizhudian, the price of LED bulbs was more expensive when they first came to the market. The big brands were all over 100 yuan. Now it is the price of policy subsidies and promotions.
It is understood that the price of domestic brand LED bulbs is relatively low, about 20 to 40 yuan. Pan Wenbo, founder of Guangzhou International Lighting Exhibition, revealed that LED bulbs now have a tendency to revert to the vicious competition of energy-saving lamps. In a wholesale market in Zhongshan Guzhen, the various components of LED bulbs have been standardized and can be assembled by themselves. For example, a 3 watt LED bulb, the module cost is about 7 yuan, in order to seize market share, some 5 watt LED bulbs even sold for only 12 yuan. Under vicious competition, what is produced must be the price of the goods. As a result, the products that are not satisfied by the consumers are produced, making it difficult to promote LED lighting, thus forming a vicious circle.
Low-cost LED bulbs are difficult to replace bulbs and lamps. Because of their high consumer acceptance and high replaceability, they are the most demanding alternative light source in the LED market. Taking a 9W LED bulb as an example, the brightness is equivalent to a 60-watt incandescent lamp, which can save 80 compared to incandescent lamps, 50 saves energy-saving lamps, and has a service life of 15,000 hours. Based on the calculation of Guangzhou's first electricity of 0.6 yuan, on the basis of one year of use, the initial purchase cost of one year is also lower than that of incandescent lamps and electronic energy-saving lamps.
However, LED bulb products also have shortcomings. For example, incandescent lamps can be used in kitchens, and LED bulbs are easily damaged if they are used in kitchens to be easily affected by soot dust. In addition, LED bulbs are used in places where incandescent lamps are replaced. More popular places, but the current high price of LED bulbs, consumers obviously can not accept. Insiders pointed out that the low price of LED bulbs is the demand of China's lighting market. Reducing cost and waste is one of the foundations for reducing LED prices. In the sales channel, the batch-zero method is adopted. It is also an effective way to reduce the price of LED bulbs by reducing the cost of sales.
Seed processing plant is a complete set production line composed of seed cleaning and treating procedures. Seed cleaning procedure will remove the dust, big size impurity, small size impurity, stones, immature, eaten, sicken seeds out. Seed treating procedure will coat the protective chemical film on seeds' surface to improve seed germination rate. One Seed Processing Line normally including following equipment: seed cleaner, seed grader, de-stoner, Gravity Separator, seed coating machine. We will offer particular plant solutions for every different seeds processing requirements. Oversea installation and training is available.
We built over 10 sets seed processing plants at home abroad. Following are two cases reference.
