the brightness increases, so does the total amount of heat

Toshiba Lighting & Technology improved luminous efficiency by dispersing more than a hundred LED chips in a large package to prevent heat from concentrating. For its previous products, the company used Nichia Corp's general-purpose LED package. But, this time, Toshiba Lighting & Technology developed its own LED package, aiming at a total flux 1.5 times higher than that of the company's former product that is equivalent to a 40W incandescent lamp in terms of total flux.
However, as the brightness increases, so does the total amount of heat. Therefore, the company elongated the chassis by 10mm to 119mm to expand the radiating area.

lighting company and leading supplier of energy-saving light-emitting diode (LED)-based light sources, has placed a multi-unit order for Veeco's TurboDisc? K465? gallium nitride (GaN) Metal Organic Chemical Vapor Deposition (MOCVD) systems to support its production ramp.

"Bridgelux is focused on enabling mass adoption of LED-based solid-state lighting by reducing the cost of light for the general lighting market," stated Mark Swoboda, Bridgelux Chief Executive Officer. "Bridgelux is committed to the advancement of our core LED materials and process technologies. We expect Veeco to be a strategic partner for our manufacturing expansion.
