LED light for the road? No problem.
OSRAM Opto Semiconductors offers solution with integrated lens
The Golden DRAGON oval Plus LED from OSRAM Opto Semiconductors provides perfect illumination for energy-efficient street lighting without the need for secondary optics. The highlight is the new integrated lens. Its oval radiation pattern delivers directed light, ideal for street lighting and reduces the effort for this application considerably.
Since different roads call for different lighting concepts, the LEDs are available in different white tones. Their efficiency is typically 90 lm/W in cold white (6500 K color temperature) and 80 lm/W in neutral white (5000 K). The warm white version with a color temperature between 2700 and 4500 K has been developed for any illumination that has to create a welcoming atmosphere, for example in a historic city center. At 4500 K it achieves an efficiency of typically 65 lm/W and produces a particularly pleasant light.
The main benefit of the new LED is its integrated lens. This makes secondary optics superfluous and enables street lighting to be provided with much lower effort. The LED is also suitable for standard solder processes. Dr. Markus Klein, Head of SSL Product Development at OSRAM Opto Semiconductors, commented: “Our ‘street lighting LED’ combines various benefits in one place. It is highly efficient, and has a long lifetime due to its silicone lens. Additionally it offers good visibility at night because the LEDs can be arranged in the system to distribute the light accurately. This new light source also makes it easier to upgrade to efficient street lighting with LED technology.”
The Golden DRAGON oval Plus is suitable for all applications that call for linear efficient lighting with a homogenous oval light pattern, particularly street and tunnel lighting. It meets all the requirements that apply to homogenous illumination. The LEDs are also lead-free and mercury-free and therefore fit for the future of more energy efficient, environmentally friendly outdoor lighting.
One of the world's smallest LEDs in the 1 W sector
Small in size, big on performance – that is the new ultra-white OSLON SSL LED from OSRAM Opto Semiconductors. Its package measures just 3 x 3 mm but in terms of luminous efficacy the LED is among the greats with a typical value of 100 lm/W. Its properties provide the basis for high application efficiency thanks to high efficacies even at high currents, simplified thermal management, high reliability and a beam angle of 80°. The LED provides light that is ideal for spotlights, desk lights and ceiling floodlights.
The OSLON SSL is manufactured using the latest chip technology, ensuring a high luminous efficacy. At an operating current of 350 mA this light source achieve a typical brightness of 110 lm in ultra-white (5700 and 6500 K), with a maximum possible luminous flux of 130 lm at present. At an operating current of 350 mA and a color temperature of 3000 K it achieves a typical efficiency of 75 lm/W and a brightness of 85 lm. And brightness is an impressive 155 lm at an operating current of 700 mA (warm white). The advantage here is that applications that demand high lighting levels can be completed with fewer LEDs.
