    DIY 4x12 3500K/5000k lm561c two channel board

    It looks nice now. I am glad that u listenened to my advise to line up the leds with some snap function in the design program. You are a hypocrite indeed. In the begin I was nice to you. At the point when I and some others told you that dimming with a 10V source was not necessary you got angry...

    led casing made of mdf? (260Watt)

    Meanwell states that it is not good to power the driver without load. Dont wire the thermal switches in series with the cob. Wire them to the A-C input of the driver to switch the driver of. I have the ds18b20 already on my cobs and I dont want to switch the lights to out If not necessary. I...

    led casing made of mdf? (260Watt)

    Yes because mdf swel up in moist places If not treated. I could use plywood too but it would be nice to give it a transparant finish.

    led casing made of mdf? (260Watt)

    The plan is to dim down If the cobs get hotter than 85C• (185F•) for a longer lifetime of the cobs. I guess that the cobs only get that hot If a cooling fan gets defect. The sensors where on the led to calculate the lumen output in the first place. Then convert lumen to ppf for the given cob.

    led casing made of mdf? (260Watt)

    I have 5 Cree CXB3590. 4 of them run on 50Watt maximum (2700K). 1 of them run on 60Watt maximum (6500K). They are on actieve cooled pin heatsinks and never got hotter than 52C• (126F•). The temperature of the cobs is measured on the Tc point with ds18b20 sensors. the auto ignotion point of mdf...

    DIY 4x12 3500K/5000k lm561c two channel board

    the leds are not placed in an even grid and why 6 strings of 3500K and then 6 strings of 5000K. Why not 1 string 3500K and then 1 string 5000K and then 1 string 3500K and then 1 string 5000K.......

    On/Off functin for meanwell HLG style drivers using dimming and arduino

    Some message for vegaswinner and for everyone that wants a good idea. If u want to try the 12 bit PWM engine I mentioned before u can buy the 16 channel 12 bit PWM servo driver development board in the link. The adafruit librarys in the other link works with this board. If u use this board u...

    On/Off functin for meanwell HLG style drivers using dimming and arduino

    I dont bow for wietefras his "intellectual superiority". I can learn some things from him and i did. Good for me that i think things over first and don't just do what others (vegaswinner) say or do. This thread is about dimming and it should be no problem to discus over worse, good and better...

    On/Off functin for meanwell HLG style drivers using dimming and arduino

    Oh wait, you think that this tread is your personal belonging and u dont want to talk about other, better or different approaches to build simple elektronics. I respect that. From now on I will tell u that u are the best and that u are genius. Vegaswinner you are a true winner. I like how you...

    You need to go to the doctor and ask for some antipsychotics. Did u smoke to much? Didnt u sleep for 6 days? What is wrong with u? I am worried.

    On/Off functin for meanwell HLG style drivers using dimming and arduino

    Uhm I use a 16 channel, 12 bit PWM engine from NXP for 2 bucks. It is the other way. Coralux used that PWM engine too but they implement it in an other way.

    I share my ideas and do not disrespect u. I have a healthy dosis of competition. U call me a hater an I call u a bighead. I know my designs are better than yours. No disrespect. I invite u to be me student. I will teach u like otters teached me. No need for frustration. May the force be with u...
