Now many places have used outdoor LED display to advertise, but many friends are concerned about the outdoor LED display energy-saving effect, then in the end how to achieve outdoor LED display energy-saving? Next Regent photoelectric technical staff to talk to everyone Related knowledge about outdoor LED display.
The following are the methods for energy saving of outdoor LED display:
First, adjust the brightness of outdoor LED display: LED display itself is using energy-saving materials, but the area of ​​outdoor LED display is large, or more power, so we have to adjust the brightness of outdoor LED display according to the changes in the environment.
Second, in the structural design method: As the outdoor LED display is outside, it will be affected by environmental factors, such as air humidity, air salt content, etc., so our outdoor LED display structure design needs to take into account these, in order to save more The cost of maintenance can save energy and reduce consumption.
Third, improve the LED power supply: This plays an important role in outdoor LED display energy-saving, the current outdoor LED display directly using half-bridge or full-bridge high-efficiency switching power supply, coupled with synchronous rectifier energy-saving effect is significant to the driver IC In the constant current state, the power supply voltage is reduced as much as possible, and power is separately supplied by the red, green, and blue dies to achieve better energy saving effect.
The above introduction is about the outdoor LED display how to achieve energy-saving knowledge, outdoor LED display area is generally dozens of square meters to several hundred square meters or even greater, high brightness, large viewing angle can work in the sun, with a certain degree of windproof , rain, waterproof function. Mainly used for outdoor advertising, stations, squares, shopping malls and so on.
Carbomer
Carbomer Carbopol 940,also called Carbomer or Carboxypoly-methylene is a generic name for synthetic high molecular weight polymers of acrylic ACID used as thickening, dispersing, suspending and emulsifying agents in pharmaceuticals and cosmetics. They may be homopolymers of acrylic acid, crosslinked with an allyl ether pentaerythritol, allyl ether of sucrose or allyl ether of propylene. Carbomers are found in the market as white and fluffy powders. They have the ability to absorb, retain water and swell to many times their original volume. Carbomers codes (910, 934, 940, 941 and 934P) are an indication of molecular weight and the specific components of the polymer . This product is acrylic bonded allyl sucrose or pentaerythritol allyl ether polymer. Calculated on dry goods, including carboxylic acid group (-cooh) group - should be 56. 0 % ~ 68. 0 %.
