Poll: LED lamps overheating
Temperature issues and LED lights have featured before in recall corner – see Recall Corner: LED lamp overheating – and there is now a new addition.
The US Consumer Product Safety Commission warns of ‘LED Night Lights Recalled by Camsing Global Due to Burn Hazard‘. The CPSC has received five reports of the night lights “overheating, smoldering or melting” (no injuries have been reported).
“The LED night light contains flame retardant elements, plugs into an electrical outlet, has a white or blue LED bulb, and a clear bulb cover. “Model SBD01″, the number “E314462″ and “Made in China” are stamped on the back of the night light’s plastic white base. The night lights measure about 1 3/4 inches wide by 3 3/4 inches high,” says the CPSC.
Since the early days, luminaire manufacturers have got the heatsinking wrong – which appears to be the case here. It raises the question of when will ‘best practice’ messages and education get through?…
The danger, of course, is that LED technology itself – which I think we can all agree is a very good, power-efficient thing – will become associated in the public mind with consequences such as these, resulting from bad practice. Time for a poll!
Which aspect of an LED lamp design is a manufacturer most likely to cock-up?
