Driving 10W RGB LED Red Channel Issue
Red forward voltage @ 350 mA = 7.5
R6:  350 mA x 10Ω = 3.5V  

Where is the AL5809 going to get its 2.5Vin-out min.?



Max temperature is 85°C.  

Red: 350 mA x 7.5V = 2.625 watts
Blue: 350 mA x 11.5V = 4.025 watts
Green: 350 mA x 11.25V = 3.938 watts  

Total watts = 10.6 watts  

Without substantial thermal management there is no way these LEDs will be running below 85°C. 




  if i press on the LED it self the red channel will turn back on but
  again fails as soon as i let go of pressure.


This is a bit of a mystery.  The LEDs should be too hot to put your finger on.  Unless they are not getting the expected 350 mA. If one or two of the AL5809 fail because they do not have the 2.5V min then the current will be less than 350 mA dropping the voltage across R6 giving the AL5809s their required 2.5V. 

Measure the voltage across R6 to get the current.



I would try disconnecting one of the AL5809 and or short out or lower R6 to 2.8Ω for a 1V drop. 



Also consider using a different CCR.  The On-Semi NSI50150ADT4G has a minimum 0.5Vak and 350 mA max.



UPDATE

In the comments there seems to be some confusion as to why I made the above suggestions. 

The function of the CCR is to supply a dynamic current limiting resistance in the same manner as a fixed resistor. A CCR will have a minimum and a maximum anode to cathode voltage (Vak). The actual operating Vak is strictly a function of the supply voltage minus the LED's Vf.   


  THis confguration is poor due to "LDO dropputs of 2.5V in both Linear
  and CC regulator . and thus very sensitive to any changes V overhead

A CCR is a linear CC regulator.
The NSI50150ADT4G's 1.8V "typical" is only specified at a very specific current and thermal conditions.    Its purpose is to specify thermal performance not the normal operating Vak as previously described. See Figure 2.  

The reason I suggested the NSI50150ADT4G is becasue it is a single part that can replace three.  A CCR requires sufficient thermal management for stable operation and a DPAK package is heatsink capable. Also the current is adjustable for 150 - 350 mA and 350 mA is likely too high for thermal reasons.  

The purpose of R6 is to alleviate thermal stress on the CCRs (if needed).  R6 is not a current limiting resistor. 10Ω is not likely to work well due to the supply voltage likely being insufficient with a minimum Vak of 2.5V, Vf of 7.5V @ 350 mA and supply of 10V. The addition of the voltage across R6 will likely take the CCRs and or LEDs out of their normal operating conditions. 

If the Vf is indeed 7.5V (likely less), any voltage drop across R6 would exceed the minimum voltage required for the CCRs and LEDs.  When powered on, LED Vf starts out a about 5.5V and R6 zero. The voltage of the CCR is ambiguous as the minimum 2.5 Vak is a recommendation but likely 1.5V which is specified in the electrical characteristics as the minimum Vin.  


  The recommended minimum VINOUT voltage of 2.5V...--AL5809 datasheet


As current rises toward 350 mA the voltage across R6 will increase to 3.5V if the current were to unlikely reach 350 mA.
Three red LEDs in series are likely to reach 6+ volts at over 100 mA.
As VR6 approaches 3.5V it will be unlikely the CCRs will have sufficient voltage operate correctly. The solution is to raise supply voltage, or reduce (or eliminate) the voltage across R6 to give the CCRs sufficient voltage overhead to operate correctly. 

As R6 is the single component with a predictable voltage, measuring the voltage across R6 will give a fairly accurate indication of the amount of current flowing for troubleshooting purposes.   


  Vf is low so CC is accurate but too hot and misunderstood’s analysis
  to reduce R will make R cooler but CC (red) hotter. – Tony Stewart

Vf is ambiguous but the datasheet IV curve indicates it should be about 7.5V @ 350 mA. This a CC source so the value of R6 would have no effect on current (or red's temperature) if CCR's are working correctly.
