Description: After years of development and production; we already have the world's most specifications of waterproof and not waterproof LED panel. More for you to customize various sizes (the largest size 1000x1000mm), all kinds of shape (square, round, octagonal shaped), a variety of power brightness (maximum 300W), a variety of LED array mode (square, triangle, honeycomb-shaped ), a variety of applications (advertising light boxes, high-brightness of the large-scale projects, home lighting) LED panel. The LED panels are used the top light efficiency of LED chip, the real energy. The unique design and manufacturing so that it is efficient and reliable products and safe, more aging test of 24 hours over three years, years of practical application of engineering around the world to good effect! Independent intellectual property rights and patents. More specifications, this article lists the advantages and disadvantages of the various models, and hope to help you choose the right LED panel.
The LED panel Category:

• Classified in accordance with the form factor
  While we can to customize the size and shape according to your requirements; but this requires additional costs, the unit price is relatively high. Recommended to choose a standard size, the square of the standard size is generally 300x300mm, 300x600mm, 600x600mm, round standard size diameter of 300mm, 400mm; details, see the specifications of each model are different depending on the model.
• In accordance with the brightness of the LED panel
  LED panel brightness and size of power, the power the greater the brightness the higher ;ease of understanding, 600x600mm size LED panel, for example: our existing product brightness 640Lm 1080Lm, 1800Lm, 2100Lm, 2520Lm 3360Lm, 5200Lm, 5600Lm, 9000Lm, 10000Lm, the highest we can customize 20000Lm LED panel.
• According to the LED array and LED spacing
  LED arrangement is divided into squares arranged in triangular arrangement of the honeycomb-shaped arrangement; square array is the most commonly used, the triangular arrangement of minimum distance of dodging; square arrangement of uniform optical depth and LED spacing ratio is 1:1.43, the triangular arrangement of the smallest uniform optical depthand LED spacing ratio is 1:1.25. If the shade or advertising canvas and LED panel spacing adequate, suggested the use of a square array; the triangular arrangement of the unit price is higher. The honeycomb-shaped arrangement of the very few customers use is not recommended.
  LED spacing: 16mm, 25mm, 30mm, 33mm, 45mm, 50mm, 66mm. Light away from the smaller, the more the number of LEDs used, the higher the brightness, the higher the power consumption.
• In accordance with the input voltage.
  Classified in accordance with the input voltage, input voltage of the LED panel 9.6V, 12V, 19V, 24V, 12 ~ 24V (built-in constant current LED panel), in the practical application of 12V more constant voltage drive, easy to extend, for many year slarge-scale practical application of engineering to good effect, reliability, security has been a good test. Small-scale using the recommended built-in constant current LED panel, using the constant voltage drive, easy to expand, reliability requires the test of time (in June 2011, small quantities of practical application).
  9.6V and 19V LED panel, high luminous efficiency 110Lm / W, recommend one-on-one using the constant current power supply
  Built-in 12 ~ 24V, constant current LED panel, high luminous efficiency 105Lm / W, wide voltage constant voltage drive, easy to expand, the future direction of our development
  12V, 24VLED panels, luminous efficiency lower 90Lm / W, reliable performance, easy to install, the constant voltage drive, scalability (one power for driver more LED panel, a power driver, according to the actual need to increase or decrease. need to replace the drive power, you can use low-cost dimming system)

• In accordance with the drive mode.
  Classified in accordance with drive way, you can use a constant current power driver, the constant voltage power supply driver .The advantages of constant-current drive efficiency is high, the disadvantage is that only one power drive to one LED panel, the constant voltage drive advantage is that a power supply can drive one or more LED panels of different sizes, different power consumption can be any combination.
  
  How to choose the LED panel

• Brightness levels - this is based on actual customer demand, replace the fluorescent tubes, 50% of the original fluorescent tubes power to select the LED panel
• Color and color rendering index, optional colors: Warm White 3000 ~ 3500K Neutral White 4200 ~ 4700K, White 6000 ~ 7000K; Ra 70/80 optional
• The range of applications to select, use light boxes backlight recommend the use of RX-ALF3528 series,Lighting source of light is the RX-ALF5050 series
• Efficiency requirements, you can accept the high price of the constant current power supply, each LED panel corresponds to a power, it is recommended to select 9.6V products, matching the constant current power supply drives
• Higher efficiency requirements, the use of a common constant voltage power supply drive, it is recommended to select the built-in constant current LED panel, input voltage 12 ~ 24V, and the absence of a long period of practical application, a large area be used with caution (maximum area of less than 10m2)
• Require high reliability, large area, please use the 12V LED panel,Large-scale projects, many years of practical application; high reliability.

  Note:
  12V the LED panel derating of 15%, 0.1V voltage drop corresponding to 3% of the current changes;9.6V LED panels derating 8%, 0.1V voltage drop corresponding to 7% of the current changes, it is recommended that the constant current driver, if you must need more high-precision drive constant voltage drive, recommend the use of specifically tailored for 9.6V LED panel EF-DC2A, and EF-DC-8A.
  In conclusion :
   If a constant current source drives an LED panel, recommended 9.6V panel + constant current power supply
   If a power drive multiple LED panels, the use of an area of less than 10m2, built-in constant current panel + constant voltage power supply is recommended
   If you need high reliability, extended ease of installation, a large area of use, please use the 12V panel +12 V constant voltage power supply
