- That 60W-equivalent LED: What you don’t know, and what no one will tell you…
- How do you educate consumers without putting them off LED replacement bulbs/luminaries? I have been working on an home LED lighting system on-and-off for a couple of years now and I can relate fully to Light Squared's comment. Also, tThe LED luminary design learning curve is massive - especially if your knowledge of thermodynamics is not top notch. Unfortunately (or fortunately) the "standard" bayonet fitting (in my country) is regularly in a configuration which restricts airflow and heat dissipation. I have been forced into developing and selling a system independent from these old fittings and it turns out, I cut the costs of integrating a "fitting". Luckily, at the life expectancy of a well designed luminary I have the luxury of not needing a fitting. The LED is integrated into the entire luminary design, lampshade and all. This way I can also control (to a point) the use of the LED lights. Still, it is proving difficult to convince consumers that buying the LED lights with standard fittings are "risky" without putting them off LED lights all-together. As a side note: I have noticed my toddler likes looking at the LED lights when I am not watching him :P so I have dimmed them considerably to protect his eyes. --- I guess this means it would be advisable to shade the direct sight of LEDs in luminaries for consumers, even if it means integrating a lens to disperse the light more - some some LED lights, such as from Phillips, do. Without proper design - as Ed's article points out - these necessary additions need thermal consideration = more design time + less options + more war with the cheap market. To "beat" the market I focus on selling my products to off-grid homes and new houses.
