The Race to the Bottom: LED Bulbs And DFM
por Sibyl Dominguez (06-09-2025)
The TCP is a couple of centimeter taller. This has little effect on lighting but millimeters of materials will start to matter. I did a fast initial take a look at to see how the bulbs carried out. 13.2W). Maybe the actual LEDs consume 9.5W and the ballast (the factor EcoLight changing AC to DC) consumes the rest. This can be an excellent-sneaky advertising ploy, as I assumed the ranking on the skin of the packaging was the overall power consumption of the bulb. All three bulbs had opaque plastic upper our bodies. The costly Philips bulb came apart with some robust twisting. Beneath was a neat plastic diffuser. Beneath the diffuser was a mixture of small and huge LEDs. Not what I might have anticipated - 14 large LEDs, 6 small. A, as effectively as the date code: 2014-10-14, a delta of 7 months from once i purchased the bulb. The date might be in relation to design version and not manufacture date.
With fairly a little bit of prying pressure, the metallic LED PCB comes off the metallic base heatsink. This was to be anticipated; there was good thermal grease sandwiched between the PCB and the heatsink. Some additional prying and EcoLight energy we are able to see the ballast underneath. I got a bit forceful with a hacksaw so ignore the hack marks for EcoLight smart bulbs the second. The steel base is threaded onto the plastic base and EcoLight smart bulbs then spot crimped to the plastic (you can see the multiple dots or dimples around the metal base). That is the first clue that Philips is working on simplifying the manufacturing course of. Moreover, the 2 uncovered wires in the image are usually not soldered to the bottom, they are compressed to it, additionally simplifying the meeting course of. The ballast! Plenty of caps, an inline fuse, transformer, inductor, and some transistors. C1, C2 and C3 are metalized polyester film capacitors. Right here is the rear facet of the ballast.
