Intro: LED Workbench Lamp
This lamp is for all application in you need good lighting condition. I use it at my workbench.
- ~ 2000 lm
- Diffuse, no shadows ( iced acrylic glass )
- CRI > 90
- 4000 k
- Flicker free
- optimized temperature management (heatsink < 55°C after ~ 90 minutes)
- 12 V @ ~ 2 A
Step 1: What You Need:
1 x heatsink 345 mm ( I took ct-83 from CoolTec Germany, Heatsink is 980 gramms )
also possible ( sk407 form fischerelektronic Germany )
LED Stripe (I took 4 x 300 mm 60LED/M 4000K CRI 5630 12V CRI>90)
3 x iced acrylic glass
4 x M5x12 screws ( DIN912 or what you have )
4 x M5 washer ( DIN125 )
2 x 3D printed side part
1x 12V 3A PowerSupply
Step 2: Heatsink
Cut the heatsink to 345 mm length or buy it with this length.
I you want to use your LED stripe or LED module as long as possible, use a heavy heatsink.
!!!! The normal "little" lightweight heatsinks definitely do not dissipate enough heat from your LED. !!!!
Step 3: LED Stripe
- Clean the heatsink with alcohol or isopropanol.
- Solder before stick it, cause the heatsink suck all your power from soldering iron
Step 4: Acrylic Glass
cut your acryl like in the drawing.
Step 5: 3D Print the Parts
Print both Housing parts. The second is for 8 mm Power Jack (Very common in Germany).
If needed print the angle(Winkel) parts. The angle is about 12 degree.
