Lumileds’ LUXEON HL1Z Color Line simplifies multi-color LED application development with chip-scale packaging and uniform focal length
Lumileds of Amsterdam, The Netherlands says that its new LUXEON HL1Z Color Line is a high-power, chip-scale package (CSP) portfolio of 10 direct and phosphor-converted colors that share a common focal length and footprint. Offered in small color bins and with narrow forward-voltage bins, the LEDs are said to deliver better color uniformity, better efficacy and thermal management and more consistent behavior at operating conditions.
Superior color mixing
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 colors and therefore better control of the resulting light and color. Their very small size, high-current capability, and 85ºC binning allow for higher-density arrays in a smaller space positioned under single or multiple optics.
Colors, CCT tuning, or color tunable
With direct colors, phosphor-converted colors, unique, non-saturated Fusion colors, and the LUXEON HL1Z white portfolio, it is now easier to create single solutions that deliver color, high-quality white light with a color rendering index (CRI) well above 90, and dynamic lighting that can be purpose-tuned for an interior design or even human-centric lighting. Lumileds engineers have developed implementation tables to make it simple to design the desired illumination.
Driven by application requirements
Lumileds notes that every LUXEON Color portfolio serves different application objectives. For example, the new LUXEON HL1Z color emitters are one-sixth the size of a LUXEON 2835 color emitter and deliver three times the power. For entertainment, spot and many other intense color-dependent applications, LUXEON HL1Z will prove to be the only cost- and performance-appropriate solution, Lumileds reckons, although for many strip and linear applications LUXEON 2835 will continue to deliver the best cost/performance option in the market, it adds.
Lumileds CSP innovation
Lumileds notes that its engineers pioneered CSP technology in 2013 with its LUXEON Flip Chip and has continued development over the last 12 years. The firm’s CSP LEDs 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. Particularly useful in directional applications, LUXEON CSP LEDs offer better thermal contact, higher current densities, very high reliability, superior long-term color stability, and easy surface-mount assembly with standard equipment, the firm adds.
