The Philips LED design is patented. The construction of the Philips LED bulb is unique are gives a lot of advantages:
1. It’s optimized to ensure the benefits in terms of performance and lifetime
2. The beam pattern is perfectly adjusted to distribute the light where needed upfront
3. The position of the LEDs (chips) are exactly placed like on a conventional bulb reproducing perfectly the same light distribution
4. Its gives to the LEDs extra robustness: shock-resistant, moisture proof and resistance to voltage surges.
