Mercedes Turns the High-Tech LED Lights on 2015 CLS Facelift

Instead of giving us the full picture, Mercedes-Benz has turned the spotlight on the 2015 CLS Coupe (okay, sport sedan) and Shooting Brake facelift’s front end, and in particular, the new all-LED MULTIBEAM headlamps featuring “adaptive light functions as a world first in a production automobile”, according to the Germans.

Before we share the technological details on the lights, let us tell you that from the teaser pictures of the AMG Sport Package (?) model, we see that the updated CLS has a reshaped front grille and a new bumper similar, if not identical in styling to the smaller CLA AMG Line.

In recent months, we also spotted the interior of the facelifted CLS that gets new buttons on the center console, a redesigned steering wheel and a standalone display for the infotainment system. Under the hood, Mercedes is rumored to introduce a new 9-speed 9G TRONIC transmission and its twin-turbo 3.0-liter V6 gasoline unit delivering 329 hp (333PS) and 480 Nm (354 lb-ft) of torque.

Back to the new MULTIBEAM LED headlamps, the new main and high beam fixtures employ four fast responding, high-resolution precision LED light modules with 24 individual LED chips, each of which can be controlled electronically and independently from the others.

The four control units work together with a camera positioned behind the windscreen that feed the system with information to calculate the best possible light pattern 100 times per second and activate all 24 LEDs in lamp module separately. Mercedes says that, in high-beam operation, the range was increased by about 20 percent to about 485m or about 0.3 miles.

Along with the main-beam module, each MULTIBEAM LED headlamp includes an additional module for the low-beam headlamp with four LEDs, which can swivel outward by as much as twelve degrees offering an “anticipatory camera-based active light function”.

Another neat feature (you know, cool until something goes wrong and you’re out of warranty…) is the navigation-based light function for roundabouts that activates the cornering light function to the left and right before entering a circular intersection.

“The first LED headlamps with all the adaptive functions of the Intelligent Light System have been available to our customers since 2010 in the CLS”, commented Daimler board member Thomas Weber.

“With MULTIBEAM LED technology the headlamps now are able to react even more quickly, more precisely and individually to changing traffic conditions. On top of this, there are expanded functions of which a driver will become directly aware, such as anticipatory camera-based curve recognition with the active light function. With such features Mercedes-Benz once again is demonstrating its role as an innovation leader in the automobile industry,” he said.

Innovations in Optics, Inc, Introduces UV-LED Illuminators for DLP® Applications Emitting over 15W of Optical Power

Innovations in Optics, Inc. introduces LumiBright™ 3300B UV-LED Illuminators for Digital Light Processing (DLP) applications such as 3D printing, maskless lithography, prepress digital imaging, phototherapy, and refractive surgery. The UV-LED technology offers more reliable and economical advantages over lasers and arc lamps in UV DLP systems.

DLP and the DLP® logo are trademarks of Texas Instruments. The technology uses millions of tiny mirrors to digitally produce an image with a light source. When used with ultraviolet (UV) light and photosensitive materials, DLP offers continuous scanning, as well as selective and overlapping exposures with greater throughput and efficiency than flying spot laser systems.

The Model 3300B UV-LED Illuminators for DLP comprise a densely packed UV-LED array coupled to a high efficiency, non-imaging collection optic with an aspect ratio matched to DLP chips. Its integral imaging optic is telecentric over the entire DLP and is constrained in angle to match the micromirror tilt angle. Water-cooling allows the UV-LED array to be operated at a very high current density. The result is an extremely high power, highly uniform UV-LED illuminator to provide unprecedented speed and resolution for UV DLP applications.

The Model 3300B UV-LED Illuminators for DLP support 3D printers for rapid prototyping, additive manufacturing, and tissue engineering. PC-board makers employ maskless lithography to quickly revise circuit board layouts. Traditional screen and offset plate printers utilize UV DLP systems for prepress digital imaging. Emerging UV DLP medical treatments strive for localized, high contour precision for skin lesions in dermatology and for corneal disorders via collagen cross-linking in ophthalmology.

Standard center wavelengths include 365 nm, 385 nm, 395 nm and 405 nm. Single or dual wavelength configurations are available. Two models are available to support both 0.95 1080p and 0.7 XGA format DLP chipsets providing high radiant power greater than 15 Watts on 0.95 DLP and greater than 9 Watts on 0.7 DLP.

Q&A: New LED street lights may disrupt sleep, increase light pollution

Ottawa has converted 700 streetlights on Carling Avenue to LED (light-emitting diode) technology, changing the look of the street at night, dimming views of the stars and perhaps even disrupting your sleep.

We spoke to Robert Dick, University of Ottawa physicist and author of the protocol that governs lighting in Canada’s national parks. He’s a longtime advocate for darker skies

Q. Are Ottawa’s new LED streetlights going to cause more or less light pollution?

A. More, Dick says. He says the LED technology is a cold, harsh light with more glare than the previous technology, and the streetlights are now very bright. As well, “white is actually a very bad colour to use. The blue part, the short wavelength part of the spectrum (part of white light) scatters a lot more,” which makes light go where it’s not wanted — up.

Q. But the sky looks darker with LED lights. Doesn’t that mean less light pollution?

A. “The reason why the sky looks darker is because of the glare from the (new LED) lights. In principle, they don’t allow any light upward. But those LEDs are intensely bright on your retina and your eye responds by closing down the iris and that makes the sky look dark. It looks as though you have a nice dark sky but you’ll also (realize) you don’t see any stars. That’s because your eye isn’t as sensitive” with a smaller pupil.

Q. Does this matter to my everyday life?

A. Yes. LED lights marketed today are a very white light. They contain more blue light than “softer” traditional lights. “The white light, or the blue part of it, affects your circadian rhythm,” he says — the body’s cycle of being awake and sleeping. Scientists at a symposium on sleep disorders at the Royal Ottawa Mental Health Centre in 2012 described how blue-white light (also found in computers and cellphones) tricks the brain into thinking it’s daytime, and interferes with the ability to sleep. The warmer colours we see in candles and firelight don’t cause this reaction.
LEDs: How do you feel about the new street lights?
FOR: Let’s save some hydroAGAINST: Too bright, too white.Other:
VoteView ResultsPolldaddy.com

Q. What lighting technology do you like?

A. The old streetlights were high-pressure sodium, “and very good ones, but they were getting old.” He argues new sodium lights are kind to the eyes and are now competitive with LED in energy use. “They produce the same amount of light per watt.”

He says LED lights can also use a light that’s more amber than white, but it’s not sold commercially.

Q. What does city hall say?

A. It strongly disputes Dick’s views. A memo calls them “dark skies friendly” because they have less “trespass” light — light that escapes sideways or upward. It also says the LED lights will save as much as $5.3 million a year million in energy and maintenance.

There’s a tentative plan to convert 67,000 streetlights to LED in years to come. The next council would have to approve it.

Why the City Council in Honolulu Restored Funding for LED Street Lights

What are LED lights? Some people might associate this latest buzz word with “environmentally friendly,” but few may realize the full benefits of LED lighting.

Light-emitting diode (LED) is not a new idea; rather, it has been around for decades.

You might have most commonly seen LED lights used as single bulbs in electronics, pens, or Christmas lights.

With the advancement of technology, LED has expanded to ‘clustering’ small bulbs for practical applications in a standard household light bulb. LED lights help to conserve energy and are longer-lasting and better for the environment than standard lighting.

In an initiative first introduced by Mayor Kirk Caldwell, the City and County of Honolulu plans to replace all 51,700 of Oahu’s city-owned street lights with LED lights that will save the City $3 million a year in energy and maintenance costs.

Installation of the new lights will be privately funded through a private-public partnership without investment of taxpayer funds.

Besides cutting costs, the LED lights will provide a brighter, whiter light that will cover a greater percentage of the road to make it safer for pedestrians and vehicles.

The lighting is also directed downwards on the roadway and sidewalk thus reducing light pollution into homes and businesses. Lastly, LED lights help to cut down on the City’s carbon emissions.

Why does this matter? To put it simply, energy conservation through LED lights will help to save money and reduce the City’s environmental impact.

If you need more proof, just look at several other cities like Los Angeles and Buenos Aires that have already switched to LED street lights and have seen major benefits.

In Los Angeles, the city replaced over 140,000 street lights with LED technology. Within a year, energy use had been reduced by 63.1 percent. In Buenos Aires, LED lighting has saved 670 million tons of carbon release per year and has saved 50 percent of the city’s energy consumption.

Here in Hawaii in 2013, a test pilot program of LED lights was rolled out in Mililani, Manoa, Waialae-Kahala, and Nuuanu to replace 180 streetlights. Successful results from these pilot programs triggered plans from the Department of Design and Construction to install LED lights across Oahu by 2017.

In supporting this initiative, I have fought to restore the needed $80,000 in funds that were cut in initial budget rounds to ensure that this program succeeds.

With all of the great benefits of LED lighting, I believe this is the best decision for Oahu and will provide the maximum value for the safety of our citizens and tax payers.

If you are interested in knowing more about the LED lighting project, please join us at the full Council meeting on June 4 where we will finalize the budget for the next fiscal year, or you can contact my office at 808-768-5004.

I have already seen the major difference these lights have made within our pilot program, and I am excited to see the full implementation of the project in the next couple of years.

LED Lighting: Factors for innovative LED technology

Factors for innovative LED technology

With the breakthrough of LED as light source, the focus shifted to the lighting on the combination of optical and electronic elements, in short, to opto electronics. Along the entire value chain of LED technology and processes are continuously improved in order to achieve the goal of offering innovative products of efficient visual comfort. Optoelectronic competence means to master all the new challenges in an excellent manner: From the thermal management of electronic components on the development, efficient optics to optimize the operating gear and digital interfaces and the development of appropriate tools to control software. LED Lighting – Optics Projection and Reflection

Conventional point light sources emit their light in a solid angle of nearly 360 °, LEDs, however directed, from the outset, in a solid angle <180 °. So that losses can be due to scattered light or emitted light version (red in the drawing) to avoid. It also follows from the greater efficiency of transmission at lenses compared to reflection from reflectors, better efficiency, which is reflected in the resulting light output from the lamp. For the practice, it comes down to how much light is incident on the target. Thus, for example, compare the illuminance of radiators the same characteristics over a given distance in lx / W: jobs, too, the principle of projection with LEDs.

Projection: Spherolit

With LED lighting tools for directed light ERCO uses for light, control Spherolit as tertiary lenses. Technically and in the distribution patterns Spherolit base both on the patented Spherolit reflectors, which have been proven with conventional light sources. They offer both an excellent quality of light has many practical advantages for designers and users. The Spherolit is based on dividing a large lens or reflector surface in individual, three-domed facets that control the light by refraction or reflection. The transmission of light through the polymer Spherolit from lower losses than with reflection. The manufacturing process takes place from the complex calculation and computer simulation, the precision tooling to production under the umbrella of ERCO.

LED Lighting – LED Optics

The quality of the optical effect influences on the total efficiency of an LED lighting in a high degree. For the generation of directed light, for example in spotlights, ERCO therefore uses a proprietary projection optics. A collimator as a secondary lens, the link between the LED lens on the board and the exchangeable lenses. The collimator directs the light of the LEDs in parallel, so that then a tertiary lens can form the desired radiation pattern. The principle of total internal reflection in the collimator contributes to the high efficiency of the optics.

Optical principle

The light steering in LED emitters is made by three elements: The primary lens with the lens directly to the LED chip, for a hemispherical light output, the secondary lens as a collimator for parallel alignment of the light rays and the tertiary lens Spherolit. The choice of tertiary lens determines the radiation and is based on the particular application.

Collimators

For all radiation characteristics – except for narrow spot – the three-piece collimator is suitable for the module with three LEDs. The orientation of the light beams takes place by total reflection at the side and the central lens. Precise interconnection points facilitate the safe and efficient installation.

Collimator for narrow spot

At LED spotlights and floodlights with the radiation, narrow spot, the corresponding collimator used. Its effect is based only on the optical principle of total internal reflection, which contributes to the high efficiency of the lighting system.

Spherolit

Due to the shape and material of the collimator for narrow spot, that works virtually no losses on the principle of total internal reflection and thus offers optimum efficiency in the light direction. After focusing the light beams through the collimator, the tertiary lens determined with the Spherolit the emission: from narrow beams of light across wide beams to asymmetric light intensity distributions for vertical illuminance.

Development

ERCO’s extensive experience with optical simulations made it possible to solve new challenges such as the development of highly efficient lens systems innovation. Short distances for optimum quality: Photometric Laboratory, tooling and production of optical systems are located on the same site at ERCO, so computer simulations, prototypes and production parts can be directly compared.

LED modules

An LED module is composed of the individual LEDs, which are soldered to a circuit board. ERCO relates the LEDs from major manufacturers worldwide, specified for luminous flux, luminous efficacy, colour rendering, colour temperature or light colour and uniform properties for series production. Selecting appropriate LEDs, and their arrangement on the circuit board is carried out in dependence on the respective illumination object. To optimize the overall system ERCO develops the specific boards themselves. With appropriate layout for the particular radiation characteristics, precise connection points for the secondary optics, whilst ensuring optimum heat dissipation of the LED chips on the PCB to the housing

Board for projection optics

Board for reflective optics

In optical systems that direct the light through a light mixer, improves a high reflectance of the plate efficiency. Therefore, receive these boards a white paint. Optical system according to an adjustment of the LED array on the PCB.

Neutral white and warm white

ERCO has LED lights with the light colour neutral white or warm white. Designers can thus adjust the light colour the material colours and room atmosphere or working with hot and cold contrasts.

The production process of LEDs leads to a certain variation in colour location of LEDs, which are sorted in so-called binning. Uniform light quality requires the strict selection of components from defined binning.

Warm white LEDs

The relative spectral distribution of the warm white LED with luminescence agrees well with the relative sensitivity of Hellempfind-pin of the human eye. This results in a high luminous efficacy and good colour reproduction.

RGB LEDs

The RGB LEDs are on for mixing highly saturated coloured light. White light from RGB LEDs does not a satisfactory colour reproduction quality, and is therefore less suitable for colour-critical lighting applications.

RGBW LEDs

The combination of RGB LEDs with warm white LEDs combine the advantages of both systems: RGBW lights generate one-hand variable shades of white along the Planckian locus with excellent colour reproduction, on the other hand, however, until well colour light of pastel colours in the high area.

LEDs (Light Emitting Diodes) are semiconductor devices that convert electrical energy directly into by electroluminescence light. Robustness, durability and high light output with further growth potential are among the outstanding characteristics of the LEDs. White LED light is free of ultraviolet and infrared components and therefore advantageous for conservation. Daylight white LEDs provide greater efficiency, warm white LEDs have a better colour reproduction quality.

LEDs are dimmable and switching stability, they are therefore ideal for light control and additive colour mixing. Unlike other light sources, RGB LEDs, no transmission losses through colour filters. To the light output of the LEDs to the full temperature-sensitive, good thermal management is essential.
