Select the heavier the more LED lighting products 'material'?

As the white ban promulgated, incandescent lamp is accelerating out of China market, in addition to a few remote areas, the domestic lighting market at present actually mainstream energy-saving lamps. But as the fourth generation of green lighting, LED lighting thunder has completely overshadowed energy-saving lamps, become the focus of the current lighting. Now with the improvement of the each link, upgrading of materials, LED lighting products price has more and more people, gradually from commercial lighting to ordinary people.

heard of such a small story before a person's time to buy LED lights, the boss recommended to him two price is as the same lamp luminous flux, a 6 w a 8 w. Finally the person chooses 8 w, asked him why he don't choose the 6 w, finally the reason is that the same price, why should I choose 6 w, 8 w significantly larger than 6 w! To look for this, also can't completely blame dilettante consumer, after all, LED lighting is, which emerged in recent 10 years and ordinary consumers come into contact with the LED lighting is also in recent years. Some manufacturer not actively guide the consumer, in order to cater to consumer, deliberately in the case of luminous flux constant power do the products is very high.

the current understanding of LED lighting products we still stay in incandescent lamp, energy-saving lamp, that power is everything. As an ordinary consumer, don't know the luminous flux, don't know lights, don't know what color temperature, refers to the parameters, and so on, how do we choose LED lighting products? In fact beyond compare wattage, price we can have a very important parameter, that is weight. The weight of a product contains a lot of product performance, this article will start from a complete layman's point of view, to teach you how to choose a good LED lighting products.

　　1. Drive

there are several kinds of LED driver from driving mode can be divided into constant current and constant voltage; Separated off from circuit type power supply, resistance capacitance step-down, linear constant current IC, switching power supply and space left turn off the power supply and the isolating switch power supply. Resistance capacity step-down and IC linear driving mode of constant current circuit is relatively simple, only a few general circuit components, the power supply itself flaw is more, the security hidden danger is big, so the power itself is very light. And switch power supply circuit is more complex, more electronic components, such as transformers, electrolytic capacitors are particularly heavy quality component, sometimes considered themselves from the power supply and lamps and lanterns is also need to glue the power the entire interior space, so this kind of product quality is very heavy, relatively less power hidden trouble, more safety. So which is the low-end product which is a high-end products, to let go a weigh in contrast to know.

　　2. Structure

the service life of the LED lighting products in addition to is decided by the LED itself, there is another important factor is the heat dissipation. Cooling conditions good product life is longer, cooling bad product life is very short, and heat dissipation is good or bad is determined by the structure. You buy LED lighting products we can't let the sales staff light products a few hours to our perception, the scene could not have measuring equipment, then we how to approximately determining the cooling capacity of a product? Actually it is ok to get weigh in hand.

the LED lamps and lanterns of the shell is mainly used to 3 kinds of metal, ceramic and plastic materials. Metal material for heat dissipation of lamps and lanterns, best ceramic, plastic worst; Now also has a lot of manufacturers with the method of metal plastic package, can meet the cooling requirements, and can guarantee security. Metal, plastic or ceramic, or metal and plastic, to let go is had in the judgment. So a product heat dissipation is good, we can simply come out in his hand, heavy manufacturers is willing to put 'is', light is certainly cooling effect is poorer.

take into account other factors, although not absolutely measure by using the method of 'weight' by the quality of lighting products, but also can provide certain guidance and reference for us to choose. Science and technology changes with each passing day today, some high-end customer requirements not only stays in the above two aspects, demand for higher lighting products, such as high refers to, color temperature requirements, glowing effect, etc. At this time how to judge a product further? It needs to sales staff to give us a few minutes of light show, such as high show refers to the products we need, you can turn the light on some gorgeous and the colour difference of object, if the effect and close to the sun effect and color no obvious change, it refers to is higher, so can roughly determine product color rendering index on any account; If you need good light effect, we can turn the light on metope can judge the effect of light; If it is color temperature requirements, but that was to choose their favorite color!
