telioskorea Posted October 31, 2019 Share Posted October 31, 2019 I have made air cooling uv led lamp and tested more than 500 hours. it is 3.6w/pc*21/pc=75.6W one. Operating voltage is max.25.4V, but I fix my dc power supply(smps) to 23.5V for continuous LED lighting and no clogging. Printer is Epson p600, 8channel one. I can enjoy 1440*1440 resolution printing long time, maybe more than one year without any clogging of printhead. In my experience, bad Uv ink damages printhead seriously even though you lowered led power supply to enough safe zone. Bad ink break the inner mechanism of printhead within several hour continuous printing. Pls try to find quality uv inks to keep printhead in high condition.

Padrão de feixe de 120 graus e cura a área de impressão completa. Hello! I am trying to assemble a UV printer. You said you don't have to cut the printer if you use this slim LED. Just buy this LED and a cooler and it's all right? Did you use any other equipment? These are the ones I am considering buying: COOLER: https://pt.aliexpress.com/item/4000108937485.html LED: https://pt.aliexpress.com/item/4000224260797.html Please tell me if they would work for the printer.

reptilesink Posted January 6, 2020 Share Posted January 6, 2020 Yes they should be ok, you will need a heatsink to mount the leds to and a suitable power supply for them. 1 Quote Link to comment Share on other sites More sharing options...
AMN Posted January 6, 2020 Share Posted January 6, 2020 These here are ok? Heat sink: https://pt.aliexpress.com/item/32893287087.html Power supply: https://pt.aliexpress.com/item/4000052505625.html This power supply is 24V. Some links on this product say that the LEDs can be powered on 24V and others on 26V. I believe it works with 24V. What do you think? Should this font work? Thanks!

AMN Posted March 11, 2020 Share Posted March 11, 2020 Hello, I went back to my project. This is my adaptation for the UV LED. I used the Epson housing. Then I went to test the LED. It heats up a lot. When I turn on the voltage is at 27V and within a few minutes it drops and stabilizes at 24.7V. I'm afraid about that. Do you think this structure will be able to support? I accept suggestions! Thanks. Quote Link to comment Share on other sites More sharing options...
Pompoko Posted March 11, 2020 Author Share Posted March 11, 2020 Hmm I set one of these 12v 1A and it was more than enough to cure ink I used so go down as low you can ...Save your printhead life ... 1 Quote Link to comment Share on other sites More sharing options...
AMN Posted March 11, 2020 Share Posted March 11, 2020 Hello Pompoko! I am using a power supply that I bought with the LED. According to the manufacturer, the LED needs 26-30V and 1200mA. Did you ask me to be careful with the life of the LED or the print head? Thanks. Quote Link to comment Share on other sites More sharing options...
Pompoko Posted March 11, 2020 Author Share Posted March 11, 2020 Both ....led life and printer head .... what china guys suggested is use 12v and 1A constant current PSU it cure ink well so I think not extra power and extra heat is needed.

reptilesink Posted March 11, 2020 Share Posted March 11, 2020 (edited) The main thing is to limit the current to 1200ma or less. If you overdrive them it will damage them. Also you should have a larger heatsink than what you are using, heat is the biggest killer of led's.

AMN Posted March 12, 2020 Share Posted March 12, 2020 Hello Reptilesink! I measured current on my LED and it marked 1320ma. How many volts do you feed it? Thanks Quote Link to comment Share on other sites More sharing options...
reptilesink Posted March 12, 2020 Share Posted March 12, 2020 The current needs lowering as it's over driving the leds. Are you using a fixed current power supply? Going by the suppliers spec to get optimal performance stay within their limits but you can run a lower voltage. Quote Link to comment Share on other sites More sharing options...
AMN Posted March 12, 2020 Share Posted March 12, 2020 That's the font I'm using. I bought from the same seller along with the LED. Output Power - 200W Output Voltage - 25-36V Output Current - 1,3A When I turn on the LED, I measure 24.7V and 1320mA Quote Link to comment Share on other sites More sharing options...
