led flat panel drop ceiling lamp market competitiveness has been fully reflected
LED lighting has just risen in the traditional fluorescent light-based T5, T8 grille for the main LED flat-panel lamp competitors. With the price of LED flat panel lamp is close to the traditional grille, LED flat panel drop ceiling lamp market competitiveness is fully reflected. LED flat panel drop ceiling lamp as the traditional grille lamps and white board lamps replaced by more and more popular.Technological innovation and economic development, unknowingly change people’s lives. Today’s protagonist to be introduced is one of them: LED flat panel lights.LED flat-panel lamp using a unique SMD patch as a light source, coupled with light guide plate and (or) diffusion plate, LED flat-panel light design not only to provide lighting, and add artistic beauty.At present, the main use of LED flat-panel lamps are office lighting, classroom lighting, hospital lighting, hotel lighting.LED lighting has just risen in the traditional fluorescent light-based T5, T8 grille for the main LED flat-panel lamp competitors. With the price of LED flat panel lamp is close to the traditional grille, LED flat panel drop ceiling lamp market competitiveness is fully reflected. LED flat panel drop ceiling lamp as the traditional grille lamps and white board lamps replaced by more and more popular.First, the classification of LED flat lightBy shape:LED flat panel drop ceiling lamp can be divided into square, rectangular, round, round and so on the outside. (Usually with the traditional grille light shape, or else replace it?)Specifications Size:300mmx300mm, 300mmx600mm, 300mmx1200mm, 600mmx600mm. (These are the basic modulus of the space.) Hey, what is the modulus? Go right and ask your mother to try it.)By installation:Mainly flat-type (T-keel), embedded (hole), buckle-mounted (triangular keel); suspended and ceiling. (Hey, what is the keel? Really want to know please leave a message, the next special article describes the keel and modulus.)By light way:There are side-emitting LED flat-panel light and back light LED flat-panel lamp (direct type) two. (Ie, side-in and straight-down, er, forbid association).The following special You Shi Galaxy products, for example, take a look at several installation methods:There are different ways of light, look at the shape difference, followed by a special presentation on the pros and cons:Second, the side light and back light LED plate light the advantages and disadvantages1, side-emitting LED flat-panel lightsThe side-emitting LED flat-panel lamp is mainly composed of a frame bracket, a diffuser plate, a reflector plate, a light guide plate, a driver and a light bar.At present the main light guide material is PS (Polystyrene) polystyrene, PC (Polycarbonate) polycarbonate, PMMA (polymethylmethacrylate) (polymethyl methacrylate) acrylic material.Side-emitting LED flat-panel lamp of the main deficiencies:First, energy efficiency is low. It is not difficult to imagine, LED placed around the light guide plate down through the light guide, the efficiency is lower than the direct type, resulting in lower overall energy efficiency.Second, the light guide plate quality requirements are higher. If the design is not good, there will be middle bright, dark on both sides, or into the light side bright side, or the brightness of different angles inconsistent phenomenon, affecting lighting quality. (To be good at work, we must first of its profits, the product should be done, the materials in place, how to say that Tonglituo couplet to?Third, the reliability is relatively poor. As side light plate light guide plate, reflective ink and reflective film is always at a relatively high temperature, it is easy to aging yellowing, resulting in lower luminous efficiency, lamp life greatly reduced.2, back light LED flat lightBack light LED flat-panel light, is the direct type, the light source is evenly distributed behind the diffuser, directly down according to.Back-lit LED flat panel lamps have the following advantages over side-emitting LED flat-panel lamps:
First, energy efficiency is high. LED light emitted by the diffusion plate direct exposure to improve the lighting system energy efficiency. (The advantage of going straight is efficiency.)Second, the low cost. Eliminating the cost of light guide plate, making the cost of lighting lower internal space, the design is more flexible.Third, light lamps. Lamp quality is reduced because the light guide plate is omitted.Fourth, high reliability. We know that in the lamp design, the performance of various components and materials used will determine the performance of lighting products, components increase, reduce reliability. So if the use of better quality (note Oh, this is the premise) diffusion plate, lamps can guarantee a longer life.Is it really there is only the advantage of the product is not inferior? That we all use the straight-type Well, what side into it? As the saying goes: There is no sweet sugar cane.Backlight LED flat-panel lamp is the main shortcomings can not be done too thin. the reason is:First, LED light source and diffusion plate to have a certain distance between, otherwise it will see from the visual point of light. (So straightforward is often difficult to accept.) This will inevitably lead to increased thickness of the lamp, so that the cost of lighting with the shell to increase. (That thin as the future of the onion skin, can not stand the cost to split.) And the thickness increases, it increases the light transmission path, so that the energy efficiency of light, need to find ways to overcome.Second, because the lamp beads are fixed on the back plate, if the back plate with the entire aluminum plate, then the cost will be high. If the strip of aluminum plate, fixed and positioning is a problem.Third, LED flat-panel lights should be shipped outlookFinally, we look at the future in one sentence.No, I would like to make three points:First, the market acceptance gradually increased, the market gradually expanded sales. LED flat-panel light because of ultra-thin, sought after by the market. LED flat-panel lamps should use the characteristics and advantages of LED itself, to meet the practical needs and large limits to play under the premise of light energy efficiency, the ultra-thin lamps, personalized design, so as to the future of general office lighting and commercial lighting market Will occupy a place.Second, a variety of features customized LED flat panel lamps will appear. With the use of LED-driven technology advances and the development of intelligent systems, LED flat-panel lamp development will also show diversification. Such as dimming LED flat-panel lights, LED lights and other series of new products will be gradually sought after in the market.Third, the maintenance of difficult problems will be resolved. Different from the traditional fluorescent lamp grille lights, LED lamps and lanterns if the light is broken, the whole lamp should be replaced, the maintenance cost is relatively high. This is a common problem faced by all LED lamps. I believe that as technology advances, there will be a corresponding solution.
