How To Wire With DMX512 Digital Led Strip When Editting Address And Controlling

How To Wire With DMX512 Digital Led Strip

When Editting Address And Controlling

DMX512 protocol was first developed by USITT (American Theatre Technology Association) to control dimmer from console with standard digital interface. DMX512 surpasses the analog system, but it can not completely replace the analog system. 
    The simplicity, reliability and flexibility of DMX512 make it is first choice of protocol when funds permit. DMX512 is still a new field of science, which is based on rules.DMX512 console control analog led strip light drawing. 

At present, A type of led strip called DMX512 digital led strip is designed based on DMX512 protocol. Its appearance is similar to the addressable led strip controlled by SPI signal. But the designer implants the DMX512 decoding module in the control chip, And the console can directly control the led strip lights. The drawing as below:

Greeled DMX512 digital led strips have two different types: single-line and double-line types.

Single-line DMX512 addressable led strips are controlled by "A" signal of console. These led strips have no DMX512 decoding module in chips. So we have to add external mini DMX512 to RS485 decoder at Inputting of led strip.

Double line DMX512 addressable led strip are controlled by AB differential signal. Then Stardard DMX console can control it directly.

Before lighting on led strip, We must write address code in single-line/Double-line DMX512 digital led strip‘s chip by DMX address editor. 

Double-line DMX512 digital led strip wiring as below:

Single-line DMX512 digital led strip wiring as below:

the important parameters of led color: luminous efficacy, CRI and R9 (high luminous efficacy and high CRI led strip)

The higher the luminous efficacy of the LED is, the lower the color rendering index (CRI) is? And the importance of R9 spectrum 

The higher the luminous efficacy of the LED is, the lower the color rendering index is? No, this theory is clearly unsustainable. The causality of this logic is reversed. Not the luminous efficacy is low, so the CRI is high. But to improve CRI, so we have to sacrifice some luminous efficacy. However, many people still have misunderstandings about the luminous efficacy, they thought Luminous efficacy is Luminous effect.

Luminous Efficacy: The luminous flux (lm) emitted by an LED light source divided by the

power consumed by the light source (W) is called the luminous

efficiency of the LED, The unit is  lm/W. 

Luminous effect refers to the visual effect. So it is different from Luminous Efficacy.

They are two different concepts.

Factors Influencing Color Rending Index (CRI)：

Most commercial LED chips are coated with yellow phosphor (YAG), which can be stimulated by the blue light, we usually call it yellow powder. The blue light emitted by the chip complements and the yellow light emitted by the phosphor powder, synthesize the  white light.

If you want to improve the color rendering of LED, you need to involve the calculation of color rendering index. Generally, the calculation of color rendering index is R1-R8, and the chromatogram is relatively narrow.

But there is still a lack of a very important spectrum, which is the special reference R9, red R9 (saturated red color),it is an index to evaluate the quality of red reproduction. For their application studios and other occasions that need to truly reproduce skin color, as well as for the color reduction of fresh meat and vegetables has an irreplaceable role.

R9 is also an important indicator to measure the color rendering of LED. You will notice it from the following pictures, the greater the R9 is, the better the red color of vegetables and fruits is.

How Greeled improve the color rendering index of LED?

There is a saying "what is missing, to make up for what", which can not be used here more accurately. As it is missing R9, so "make up R9", then how to make up for it?
Adding red phosphor can make up for the deficiency of red spectrum of LED and adjust the color index of white LED. For example, if the original color index of an LED is 70, it may only need a little red phosphor to increase the color index of 80. To achieve the color index of 90, It is necessary to increase the concentration of red powder by multiple. 

GREELED have SMD led chips which have high luminous efficacy and high CRI at the same time, we also supply the high luminous efficacy and high CRI led strips series. If any question, pls email to:  marketing@gree-leds.com
