Converting a table lamp to LEDs

LEDs / Fixtures
Added 16 comments


We remodel a table lamp with an incandescent lamp on a 30-watt LED matrix.

Material:
LED matrix
Aluminum sheet, profile
Rivets

Tool:
Electric jigsaw
Electric drill
Riveter



Saw a circle with a jigsaw equal to the diameter of the lamp. I found an aluminum cover from an old washing machine.

We saw off two sections from the profile and fasten them with rivets to fit inside the ceiling.

We try on the matrix in the center and drill holes for riveting.

Riveting

We rivet the profile from the inside for better heat dissipation.

We insert the structure into the ceiling, connect the wires and fix the lamp.

All is ready. Thank you all for watching.

It is clear why it does not overheat: judging by the photo of the switched on lamp, the power is two times less than the declared one.

That is, the entire design of the radiator in the trash instead of replacing the defective part? I recognize the Soviet approach to cancellation ...

There is no possibility of revising the joint, for example, to replace the paste. And to replace a failed LED you need to drill rivets.

For such a price, do not change the paste-IN HELP

I mean the LEDs do not heat up, the radiator is warm.

Maybe all due to the fact that these are CMD diodes that are on the LED strip, so they have enough substrate.

works half a year does not heat up.

The radiator must warm up, otherwise the heat sink does not work.

Hi, there is enough heat sink, I made a 10-watt matrix for the house on a smaller heat sink into a small table lamp, it works for six months and does not heat up.

It works from 220, riveted without thermal paste, fits snugly, the heat sink lacks and does not heat up. Designed for a garage / little light / can be attached anywhere, costs 138 rubles in China. Specifications:

By the way ... A matrix for 220?

"COB LED matrix on a ceramic substrate. White color, glow temperature 6000K, power 30W, voltage 220V, light flux 2700Lm, PF 90, CRI coefficient 80. Illumination angle 120 degrees. Installation plate dimensions 46x45x4.5mm, LED 40x30x2mm, phosphor 25x25mm. Weight 11g. "
It costs within 400r. It's easier to put an ordinary LED. Why is there such power in a table lamp? Do you spoil your eyes?

And there is another option - to screw there an E27 watt diode lamp so on 15, and that's enough ...
... But, oh .... We are not looking for easy ways ....

By the way ... A matrix for 220?

Why rivet the matrix? Only screw connection!

Another question for the author,? How will the matrix work without thermal paste ??

Hi, it seems to me that a heat sink is too small for 30 watts ... I attached a 10-watt matrix to such a radiator and it burned out after a month.
