LED news and insight from our technology editor Steve Bush, who has been messing with LED lighting for more years than he would care to remember.
Plastic heatsink in Hella LED spotlight
Automotive lighting firm Hella is using plastic heatsinks in a range of work-lights for agricultural use.
“Thermally conductive plastics are used in place of aluminium heat sinks. A key advantage over aluminium is their corrosion resistance, and the products are also lighter,” said the firm, which is also using glass fibre reinforced plastic bracket in the lights.
The lights are: ‘Ultra Beam LED’, Module 50 LED (50mm) and Module 90 LED (90mm).
“Even in their smallest versions, they can achieve light outputs comparable with or better than xenon technology,” claimed the firm.
At the same time, Hella also revealed an intelligent battery sensor and a vehicle voltage stabiliser for agricultural vehicles.
The battery sensor delivers voltage and current data over a LIN bus. The voltage stabiliser is for running GPSs or radios and, within reason, delivers a stable 12V (and other options) regardless of how high or low the rail goes – within reason.
