Intelligent sensors provide uniformity across LEDs

Intelligent sensors provide uniformity across LEDs
MAZeT's JENCOLOR sensors team up with Dust SmartMesh technology (from Linear) to provide consistent light output across multiple LED lighting systems, a difficult and previously costly task. When merging LED and electronics components of different manufacturers, achieving and maintaining homogenous light output values proves a challenging task, especially for dynamic control options.

Linear controller simplifies LED lighting design

Linear controller simplifies LED lighting design
Integrating a multiplier and tunable phase dimmer detection, a 450V linear controller has been introduced by Texas Instruments. The TPS92410 simplifies current regulation of high-voltage LED strings and also integrates analogue dimming inputs and drive circuit protection functions. This eases the design of downlights, fixtures and lamps powered from an offline AC or conventional DC power source.

Integrated LED controller increases lamp power

Supporting up to 18W lighting applications such as TLED and PAR lamp shapes, the SSL5015 and SSL5018 LED controller ICs have been announced by NXP Semiconductors. The LED controllers offer customers a cost-effective, non-isolated solution with a high lamp power factor up to 0.9 for US and Japan (SSL5015) or Europe and Asia (SSL5018).

Create tighter beam angles with higher lumen density

Create tighter beam angles with higher lumen density
Enabling customers to create tighter beam angles with higher lumen density at a lower cost than was previously possible, the LUXEON MZ high-power emitter has been announced by Philips Lumileds. It features a forward voltage of 11.2V, a small light emitting surface of 4.2mm diameter and an undomed design to deliver smaller beam angles.

DALI interface converter offers PWM or DC outputs

DALI interface converter offers PWM or DC outputs
Suitable for controlling 3-in-1 (DC/PWM/Resistor) LED drivers, the GL-DA02 DALI interface converter has been introduced by GlacialLight. As an indoor digital lighting control system, the GL-DA02 converter is well suited for applications such as office buildings, conference rooms, factories and intelligent home lighting.

DALI to PWM signal converter for LED lighting

DALI to PWM signal converter for LED lighting
Responding to the increased demand for DALI control for LED lighting applications, MEAN WELL have introduced the DAP-04 series to make it possible to control LED lighting fixtures with DALI. Equipped with both DALI dimming and push-dim functions, the device converts the DALI signal transmitted from the controller to PWM, and then the PWM signal can control the lighting fixtures through the “3-in1 dimming” interface.

NXP Brings High Efficiency to 12V MR16 Lamps with Dimmable LED Controller

NXP Semiconductors today unveiled the SSL3401 – a dimmable single-stage controller IC for retrofit MR16 LED lamps using 12V AC mains. The SSL3401 offers compatibility with an exceptionally wide range of dimmers and transformers – working with over 80% of the most common combinations – in a compact form factor that fits in all common available MR16 GU5.3 and AR111 housings and sockets. Supporting an ambient temperature range up to 105ºC, the SSL3401 also provides temperature rollback protection. Based on NXP GreenChip™ technology, the SSL3401 generates a stable and accurate current while dimming down to below 5% of maximum light output in most common practical situations. While maximum lamp power depends on the thermal design of the lamp, a typical 7W MR16 LED lamp using the SSL3401 achieves THD below 15%, power factor above 0.9, efficiency up to 78% and LED ripple current below ±10%.
