The analysis of the LED panel lamp cost

   The LED panel lamp cost is determined by various factors. Our simple analysis for everyone.
   A, LED lamp bead cost. This is a relatively fixed, depending on the technology level of the whole industry, but also the general customers are purchasing Taiwan or American brand, price cannot control. Even if the purchase price is different, the gap is small. So, want to in this part of reduce cost, more difficult.
   Two, border. The border is usually aluminum alloy material, which belongs to the futures prices, relatively large changes, according to the current market, basically belongs to the bullish trend.
   Three, the driving power supply. LED panel light power supply, a mature industry, the price also is more transparent, the difference lies in the customer requirements of high or low and there is a little gap. But now there is a fireproof ultrathin PC material, can do 1.0mm fireproof, either through the UL certification, but also can reduce the weight of power effectively, and improve the flexibility of design. In improving the performance of the products, reduce the cost of.
   Four, the light guide plate. The light guide plate has size and thickness of different, generally is 4mm and 6mm. 6mm mature, light efficiency in general can do more than 85%, the price is relatively expensive, occupied the whole lamp at least cost more than 25%. 4mm the price will be cheaper than the 6mm a little bit of money, but 4mm technology is not very mature, can do the manufacturers, not many.
   Five, the diffusion plate. The diffusion plate material determines the price. Currently on the market there are PC and PMMA two. PMMA was at least 30% cheaper than PC. But there is a drawback, is PMMA relatively brittle, the thinnest can do 2mm, and PC to 1.0---2.0, and the toughness is good, the assembly is convenient. And can do fireproof grade 94V0 and 94V2.

The design of LED bulb lamp

    LED bulb lamp to replace the incandescent lamp, then in the lamp cap and shape are similar to the incandescent lamp. The design of LED bulb lamp requirements are as follows.
    1. Brightness to almost incandescent lamp. Incandescent lamp wattage usually only, do not pay attention to the lumen. LED bulb lamp not only has the wattage, and luminous flux. In the same light, LED bulb relative to the power of incandescent lamp can save 10 times. One thing to note, at present, from the LED bulb lamp light efficiency and heat dissipation, it also can't do more than 10 watt.
    2. Appearance should be similar. Usually the incandescent lamp to pear shaped, so LED bulb lamp should be designed into a pear shaped.
    3. The volume and weight. Because LED requires constant and radiator, LED bulb weight is greater than incandescent lamps.
    4. The lamp cap to the same. LED bulb lamp holder types must be the same as incandescent lamp.
    5. Supply voltage should be the same. The voltage of each country is different, but the LED bulb lamp generally use the switch power supply, so it can be wide supply voltage 100-240V.

The purchase method of LED tube

    Here, we introduce the purchase method of LED tube for you.
    Choose the appropriate color temperature. If the LED tube installation position is higher, can choose the color a little higher, such as: 6500K--7000K. So, LED light effect is relatively high. If, with the lower position, should choose color temperature low, such as the color temperature in the 5500K--6000K. The light is soft.
    Purchase LED tube also need to consider the appropriate power. Energy consumption of LED tube the same, the luminous flux vary greatly, selection of high quality, large luminous flux LED tube to replace the traditional fluorescent lamp, can be properly install less. Not with the traditional fluorescent lamp 1:1 substitution. In this way, more energy saving.
    Choose the appropriate appearance: General LED fluorescent lamp in the user idea still stays in the stage of the traditional fluorescent lamp. So, no matter what the situation, require light and the traditional fluorescent lamp the same. Manufacturers in the LED  tube plus soft light plate, the light looks like with the traditional. In fact, soft board when there is a loss of light energy. Generally between 15-30%. If the installation position is higher, eyes not easy often irradiation, can consider to use a transparent cover, so, can choose to power small LED fluorescent lamp, will be more energy efficient.

The advantage of LED grille down light

     Compared with traditional grille down light, the advantage of LED grille down light are the following:
     More power saving: the same light efficiency power consumption is the traditional bean pot lamp 1/8 ~ 1/10 (LED electro-optic conversion rate of more than 80%, halogen lamp, metal halide lamp belongs to the incandescent lamp variants, electro-optical conversion rate of about 20%, the rest are consumed in the fever).
     Longer life: LED beans gall lights in normal Shop Lighting temperature service life is 30000 ~ 50000 hours, halogen lamp due to heat large, life is short, is also very easy to burn out, replace the shop the maintenance cost of the lamp can be straight down 5 to 10 times. Particularly the use of halogen cup bean pot lamp, light efficiency and low, the light fades and large, life, short, has become obsolete, and slowly withdraw from the market.
     Cold light source, no radiation: LED grille down light source is a cold light source, no heat radiation and ultraviolet radiation, will not cause damage to the product. Halogen, metal halide light-emitting thermal radiation, contain large amounts of ultraviolet radiation, prolonged exposure to easy to make textiles, jewelery and other surface fade discoloration.

LED downlight and spotlight biggest difference

     LED downlight and spotlight biggest difference is emitting angle is different, resulting in differences in structure!
     LED down light: mainly used to provide uniform light irradiation range. Viewing angle Downlight are generally larger, usually around 120 degrees, generally using acrylic mask, so you can get uniform light, soft light without glare.
     LED spot light: mainly to highlight the key object through a small angle light, such as the television background wall, murals, ornaments, commodity etc.. Or increase the chiaroscuro of space, creating an atmosphere, such as big-name clothing flagship store, very strong chiaroscuro. To achieve this effect, light angle of spotlights generally small, usually 30-60 degrees. Therefore, even though it and similar downlight has the same power, the same total light irradiation, but the area is small, the brightness is high. Structurally, the spotlight is often reflected by the lens or bowl, to achieve small angle condenser, and can usually adjust the illumination angle, so when you install, you can adjust the irradiation object as needed.

LED bulb manufacturers production standards

      Now LED lamp market matures, the market is also growing up, so there are some LED manufacturers shoddy, therefore, the MIIT bulletin solicitation "led bulb performance requirements." LED bulb manufacturers based on their own experience and the standard production, that the performance of LED bulb lamp must meet the following requirements, for everyone to discuss.
      1, security: the LED bulb lamp safety should be put in the first place to consider. At present, China led bulb lights is used in aluminum metal shell, this is the most users is most likely to exposure to parts, but the metal is easy to conductive, aluminum shell led bulb lights existence of security risks of electric shock. Therefore, it is best of LED lamp radiating seat insulation to be improved, such as the use of ceramic and plastic insulating material, in order to ensure foolproof.
      2, life: a LED lamp is characterized by a long service life, but some LED manufacturers because of price competition, not use of normative materials, or professional degree is not enough, in thermal design and drive circuit design is unreasonable,  do so out of LED bulb life and not up to standard, this implicit the bad will cause damage to the interests of consumers. Therefore, should be on the service life of the LED lamp has a reasonable limit.
      3, the optical performance requirements: Some LED bulb manufacturers to lower the color to improve LED light flux, making the color performance level is low, even lower than energy-saving lamps, which is unreasonable,therefore, suggested that the LED manufacturer of light color and CRI to norms, such as home and commercial space LED bulb should be defined in Ra> 80, In addition to a diverse range of light color should be regulated, such as white light, neutral light range, and so on.
      The above performance criterion not only can be used for LED bulb lamp, some can also be used for other LED lamps, such as LED ceiling lamp, LED downlights performance norms.
