LED lighting as energy-saving and environmental protection products, has been accepted by more and more consumers, but most consumers lack of understanding of LED, also do not understand the complex terminology, so how do consumers choose LED lighting products?

 

First of all, we need to know what the core value of LED lamps is. Do you have these needs? The main advantages of LED lamps are power saving, long service life, rich lighting and fashion.

 

First, cost. From a cost point of view, the price of LED lamps is about 3-10 times that of traditional lamps. If the power consumption time is more than 6 hours a day, it is cost-effective to use LED lamps. It is estimated that one year or so will save the money to buy lamps. If it takes 2-3 hours a day, the electricity bill will not be much saved.

 

Two, value. Of course, not all activities in one's life are just for money, pursuing fashion and accepting new things is also an attitude towards life!

 

Three, quality. After deciding to buy LED lamps, you need to see what kind of LED lamps you need. At present, the state has not yet issued the quality standards of LED lamps, so the quality of LED products on the market is uneven, some very cheap groceries used in the chip quality is very poor, that is, 1W, the actual only 0.5W-0.7W, and manufacturers in order to make the brightness higher, will increase the output current of the driving power supply, which will lead to serious light fading. . Some products with independent brands should be chosen.

 

Four, after-sales service. Before purchasing, it is best to ask the agent to know how long the warranty period of the LED manufacturer for the product is, some poor products only one year, that is similar to the life of traditional energy-saving lamps, the price is still expensive, not cost-effective. As a new type of lighting product, LED lamp is still completely unknown to many people. So when we buy LED lamps, we should pay attention to three goods. The style of LED lamp is mostly the same, so at the same time of price comparison, you can ask the merchants why there is a big difference. At the same time, it is also necessary to make good agreements with the merchants to ensure the rights and interests of the products.

 

Fifth, the other is the choice of product functions, such as LED ceiling lamp (also known as LED spotlight) and LED Geshan lamp is the product of focus, mainly used to highlight the display of local lighting, according to the requirements of light efficiency can be customized 5 degrees, 15 degrees, 30 degrees, 60 degrees and other different angles of lens; LED tube lamp is a product of floodlight, mainly for lighting. Main function; LED lamp band is mainly auxiliary light efficiency, compared with ordinary T5 lamp, his advantage in addition to saving electricity can also be used in arc-shaped places, such as ceiling.

 

Specifically, how to choose LED lamps and lanterns products on the products can be viewed from the following three aspects:

 

The LED lamp is mainly composed of 3 parts, aluminum housing, driving and lamp beads. So, in the process of selecting and purchasing LED lamps and lanterns, how to start from these aspects to screen, so as to buy the best cost-effective products?

 

1, look at the aluminum shell of LED lamps. Lighting products will generate heat in the course of use. Especially for LED lamps, the heat generated by lamps and lanterns in the process of lighting is amazing. If heat can not be exported in time, it will seriously affect the luminous efficiency and life span of LED lamps. As the main part of the cooling part, the shell will bear the responsibility of the heat dissipation. So, what kind of shell is the best heat dissipation? First, the purity requirements of aluminum. For automotive aluminum parts, 6063 is the best choice of aviation aluminum, not only exquisite appearance, cooling capacity is strong. However, for larger luminaires, die casting aluminum is the best choice. Since it is a die-casting, it must be made of aluminum alloy, so the composition of aluminum alloy is more worthy of attention. For a normal alloy ratio, heat dissipation is no problem, but some merchants in order to reduce the cost, in the alloy aluminum added a lot of messy impurities, resulting in poor heat dissipation of aluminum shell. When buying, the outer appearance of the shell should be observed, and the smoothness and smoothness can be preferred. At the same time, pay attention to the thickness and surface area of the radiator, because heat is mainly dissipated from the radiator, so the radiator is very important. Some people are obsessed with the fact that the heavier the shell is, the better the heat dissipation is.

 

2, look at the driving of LED lamps and lanterns. Driving as a power unit of LED lamps is very important. When it comes to the LED drive, you can consult the businessman in detail about the various parameters of the drive, such as the output voltage and current, power factor, operating temperature and so on. The working voltage of LED lamp bead of 1W is about 3.2V, and the working current is about 320MM. If the current is too large, it will make the pearl light decay and shorten the service life. If the driving power factor is too low, such as 0.6 power factor, 10W lamp, will consume 16W power, so it is wasted. At the same time, the power factor is too low, naturally lead to the drive itself heating increased, and the electronic components are most afraid of heating, heating increases means that the electronic components themselves temperature rises, prone to quality problems. At the same time, we should also understand the repair rate of the merchants, after all, the current damage of LED lights, mainly driven. Through these, you can choose to buy a better driver.

 

3, look at the lights of LED lamps. As the core component of LED lamp, lamp bead is the top priority. At present, there are many brands of LED chips, which are mainly made in China and imported. However, whether domestic or imported, the double gold line beads structure is the most basic way to ensure the life of the beads. When purchasing led lamp, we should consult the merchant about the unit luminous flux, color temperature, chip size and power to determine whether the product meets our needs. The decay of lamp beads
