Many families will choose lighting at the time of renovation. A beautiful and stylish lighting can bring joy, joy and romance to the home. The quality of energy-saving lamps that are the core components of lighting is the key to the attractiveness of beautiful lighting. So, how to choose reliable quality energy-saving lamps?
A look at energy-saving lamps energy efficiency logo According to the AQSIQ notice, since September 1, 2008, energy-saving lamps to be labeled with energy efficiency can be listed on the market. Therefore, energy efficiency labeling becomes the most intuitive standard for judging the quality of energy-saving lamps. So how do you read the energy efficiency label? According to industry insiders, the energy efficiency rating of energy-saving lamps is divided into three levels, of which, three are market access standards, and two are the minimum standards for enterprises to obtain energy-saving certifications, and one-level is the highest value. The primary and secondary standard products differ mainly in light efficiency. With incandescent lamps as the standard, the efficacy of three-level standard energy-saving lamps is 4-5 times that of incandescent lamps, and the products of secondary standards will reach about 7 times. When used in large quantities, the advantages of secondary standard products are reflected. In the energy-saving lamp market, products are mixed, and energy-saving lamp products that are commonly seen are all three-level standards, and only a few products reach the second level. The reason why most manufacturers chose to produce three-level standard products is mainly based on cost considerations. The product cost of the secondary standard will be about 15% to 20% higher than the tertiary standard. The reason why the first-level standard products are rare is that there are still some difficulties in the current technology, which can not achieve good consistency, and the high cost leads to low cost performance of the products.
Second, look at the lamp structure Electronic energy-saving lamps are generally divided into three parts: lamp section, rectifier section, lamp section. According to reports, the lamp is the core of energy-saving lamps and the highest technical difficulty. A good way to judge the lamp is to observe the process of painting the inside of the lamp. Good energy-saving lamps, the lamp process is excellent, there is no obvious flaws, the three base color powder coated on the inner wall of the lamp tube is even and white. The rectifier can not see the internal structure. The quality of the product can be judged by observing whether the junction between the lamp and the rectifier is tight.
Three look after the effect of lighting to buy energy-saving lamps, we must look at the effect of lighting, because this is the most fundamental manifestation of the quality of lamps. How do you see the effect after lighting up? How to judge the quality of a product with a weak difference? According to reports, good energy-saving lamp products can be viewed from two aspects. First, high-quality energy-saving lamps do not become very bright immediately after they are turned on. The brightness will have a slow climb. The maximum luminous efficiency can be achieved in about 3 to 5 minutes. The reason for this phenomenon is determined by the characteristics of the trichromatic powder coated in the lamp. Another point is to look at the degree of color reduction of the lamp after lighting, and a good product can approach the natural light's degree of color reduction.
Four to see the price According to reports, the most important point to buy energy-saving lamps depends on the price. Due to the limited manufacturing cost of energy-saving lamps, the price of energy-saving lamps cannot be very cheap. There are three or four yuan energy-saving lamp products in the market. It may not even guarantee the quality of the cost price is not enough, so when you buy energy-saving lamps, you must not try to buy cheap products because cheap products may be in raw materials. And the production cost was discounted.
