Increasing the brightness of the ceiling lamp (50W LED)

Operation in my small apartment ceiling ceiling lamps showed their one major drawback: the lack of illumination in the room. This is mainly due to the small size of the ceiling and the absorption of light as it passes through the glass matte glass.



The small dimensions of the luminaire and the cooling requirements do not allow the installation of powerful lamps (both incandescent and compact fluorescent or LED) with an E27 socket.

As a result, my wife's requirements to solve the problem were implemented on the basis of a 50W LED solution (approximately equal to 3 standard 100W incandescent bulbs).



The list of required materials (Bill of materials - about $ 60 without a ceiling lamp):

• LED 50W
• Driver (power supply) for the LED
• Aluminum radiator
• Fasteners (M3 screws)
• Ceiling lamp
• Thermal paste

List of tools:

• Soldering iron
• Screwdriver
• M3 Thread Cutter
• Contactless (infrared) thermometer

Step 1 (assembly of the lamp and installation of the LED)

Remove from the lamp all the insides. In the center of the metal base of the lamp fasten aluminum radiator and driver for the LED. To do this, mark and drill the necessary holes (3-4 pieces for the radiator and 2 pieces for the driver). Then we plan and drill the corresponding holes in the radiator. Cut the threads for screws M3 in the radiator.
To install the LED on the radiator we mark, drill and cut the thread M3 on the radiator. Before fixing the LED on the radiator it is necessary to apply thermal grease on the radiator.
Solder, observing the polarity, the power supply to the LED.

Step 2 (testing)

The main task in testing the solution was to make sure that the temperature mode of the LED during long-term operation is within acceptable limits. This was implemented using a non-contact thermometer.

Now you can mount the finished lamp on the ceiling and connect to the mains.




Main advantages:

• Luminous flux: 4500-5000Lm (unsurpassed value for such lamps)
• Low power consumption compared to three 100W incandescent bulbs
• Passive cooling - no fans, no noise, no additional power supplies for fans
• Long term of operation (mine already work within half a year and I hope will work even longer)
• The existing luminaire housing is used (only the filling changes)
• Opportunities for improvement (management of brightness, color, etc.)
