Upgrade an energy saving lamp to LED # 2

The topic of rework or modernization of failed fluorescent (energy-saving) lamps in LEDs has been raised repeatedly. May the authors of these articles forgive me, but most of the proposed options are ineffective and certainly not aesthetic. This is due to the complexity of the element base and components, as well as our mentality when we are trying to blind the candy out of ... But thanks to the Koreans who released last year the wonderful LED module Seoul Semiconductors Acrich2, which connects to AC 220 V without an additional power source. The manufacturer guarantees that if the operating conditions are met (the recommended operating temperature is not higher than 70 ºС), this module will honestly work out at least 50,000 hours. We will not go into technical details, everything is clear from the picture.
 will work at least 50,000 hours
As a comment By the nature of its activitiesI have extensive experience working with various power sources. So, the resource of the power supply unit indicated by the Koreans at 15,000 hours is overestimated by about 2 times, this is provided that high-quality electrolytes are used. Chinese consumer goods, which are now on sale, are clearly not included in the category of quality goods. So, the light source was sorted out. The next step is how to cool it. To fence a banal finned radiator is not aesthetically pleasing and uncomfortable. And then there was no luck. It turns out that in Russia the radiator profile AP888, specially designed for the modules of this series, is designed and manufactured.
Profile universal
The universal profile is designed to install three types of Acriche modules: AW3221 (4 W) and Acrich2 on 8 and 12 W.

Further work on the modernization of a burnt-out energy-saving lamp was not difficult and took about 15-20 minutes to do. 1 Cut the radiator to size , necessary to ensure efficient cooling of the module. The supplier of the profile recommends the following dimensions to ensure a working temperature of no more than 70 ºС: - 4 W - 10-15 mm; - 8 W - 30-35 mm; - 12 W - 40-45 mm. In this case, you won't spoil the porridge,and I took a 50 mm radiator for 8 W. 2 Disassemble the energy saving lamp.  upgrade the blown energy-saving lamp

3 Drill holes in the cap of the base housing for mounting the radiator.

4 All components parts - radiator, module and filter to the module, are ready for assembly.

5 Then everything is simple. Install the module on the radiator, do not forget about the heat-conducting paste (I recommend KTP-8). Fasten the base cover to the radiator. We solder the wires to the module and filter. Then everything is soldered to the base.

6 It remains only to put everything together
