Luxeon simplifies multi-colour LED applications
Lumileds has announced a new Luxeon HL1Z colour Line; a high-power, chip scale package (CSP) portfolio of ten direct and phosphor converted colours that share a common focal length and footprint.
Offered in small colour bins and with narrow forward voltage bins, the LEDs deliver better colour uniformity, better efficacy and thermal management and more consistent behaviour at operating conditions, according to the company.
The undomed 1.4mm x 1.4mm emitters feature top emission of the light. With or without optics, the top emission prevents cross fading or interference between different colours and therefore better control of the resulting light and colour. Their small size, high current capability, and 85ºC binning allow for higher density arrays in a smaller space positioned under single or multiple optics.
Lumileds claims that with direct colours, phosphor converted colours, unique, non-saturated Fusion colours, and the Luxeon HL1Z white portfolio, it’s easier to create single solutions that deliver colour, high-quality white light with CRI well above 90, and dynamic lighting that can be purpose-tuned for an interior design or even human centric lighting.
Engineers at Lumileds pioneered CSP technology in 2013 with the company’s Luxeon Flip Chip. The devices do not require an additional sub-mount or substrate, are smaller than comparable LEDs with the same size chip, and can be directly attached to level 2 boards, according to the company.
