Let us disassemble Gimbal Spot Light and see what is inside and how it was made
So, we have got: 3-Inches Gimbal LED Recessed Downlight Kit 4000K Black Trim YUURTA:
Type: LED Recessed Light (Downlight, Spot Light) Gimbal (Eyeball);
Color Temperature: 4000K (Neutral White);
Power Consumption: 8W;
Brightness: 830 Lumens, Dimmable;
Construction: Thin Panel with Driver in Junction Box; No Housing Required;
Suitable for damp locations;
IC Rated – approved for direct contact with insulation;
Trim Diameter: 3.3 Inch (8.4cm)
Cut Out Diameter: 2 3/4 Inch – 2 7/8 Inch (7.0cm-7.3cm)
Height of LED Panel: 2.2 Inch (5.6cm)
Cord Length: 11.8 Inch (30cm)
Remove trim. Trim is the most visible part of light. It covers the area where the ceiling joins the light for a smooth and stylish transition between surface and light.
Here is the trim:
Here is the light without trim:
Now we have two options:
1 – Unscrew four screws to take apart case, or 2 – unscrew lamp body
Let us choose option 2 and unscrew lamp body from gimbal case:
Step 3. Let us take apart the Gimbal framework. I always was curious – How is the Gimbal frame made, what is the trick that allows lamp be so flexible with rotation about all 3 axises.
It turns out there is a metal spherical segment inside and two spherical segments outside and the rubber gasket between:
An inside metal spherical segment without lamp:
This is where the LED lamp sits. A metal spherical segment with the lamp:
And the Gimbal suspention is basically two metal parts – with spherical internal surface and a sealing ring:
So the lamp inside sits tight enogh and able to turn/rotate in tree dimentions.
Step 4. Disassemble the LED lamp itself.
Here is the internal part of the LED lamp:
And the same from othe angle:
Close up to the LED diode itself:
White roud plastic I believe has a solo perpose: fix the diode and press it down to the metal radiator (passive heat sink). Let us unscrew it:
They also use thermal paste – a heat-conductive substance that is applied between the heatsink and the LED to cool. Thermal paste improves conductivity between the heatsink and the LED.
