Lots of outstanding attributes and technical innovations will once again make it the benchmark in its class - and undoubtedly also to be successful for our item. The SLK is a roadster with character, and everyone will want it.'
Striking, athletic and chic
The designers have tailor-made a body for the SLK that emphasizes its classic roadster proportions. Behind the long hood is a compact passenger compartment coupled with a short rear overhang - key attributes that characterize all the classic roadsters from Mercedes-Benz.
Professor Gorden Wagener, Head of Design at Mercedes-Benz Cars: 'The SLK continues the illustrious roadster tradition of Mercedes-Benz, and excitingly takes it into foreseeable future. The design idiom accentuates its lively, athletic presence, and likewise sculptural. It expresses personality and sensuality. The same refers the room. High-grade materials, lovingly crafted details and extremely exclusive finish characterize the essentially very sporty atmosphere.'
Striking front end
The first eye-catching feature is an upright radiator grille that bears the new Mercedes-Benz brand look. The grille emphasizes the long and well-proportioned hood, meet your needs its light-catching contours it already hints at the roadster's dramatic qualities. The wide radiator grille bears the Mercedes-Benz star within a prominent central position and displays a powerfully contoured chromed fin at best. The clearly defined headlamps complete the form of brand new SLK's face and resemble that for this legendary 190SL from the 1950s, can be regarded by many people as being the original 'SLK'. However, the designers did doesn't just focus using the past; with the new SLK's front end they also intentionally produced a close visual link utilizing the new Mercedes-Benz SLS AMG 'gullwing' and the new CLS-Class.
The impressive result of their meticulously detailed work is this in spite of slightly more striking, steeper front and larger frontal area, the Cd value has been cut to 0.30 - a brilliant achievement (the predecessor model's Cd value was 7.32).
Dramatic lines
The timeless, classic model of the side profile that's not a problem classic roadster proportions embodies aesthetics in the highest caliber and can be a visual cue to the vehicle's sportiness and driving pleasure. Fine details show the care that already been taken your Mercedes-Benz designers. For example, a molding conceals the trunk joint, so that the side line doesn't interfere, for it usually does with similar roof concepts. The ventilation grilles in top fenders having a chromed fin are paying homage to the famous Mercedes-Benz roadsters of the 1950s. Your new SLK, they make up the perfect start for a component line, which flows on the muscular rear fender, using light and shadow in order to style and timeless aesthetics to the perimeters. Meanwhile, the top edge within the wide headlamps - which for extremely first time feature LED technology - also appears circulate into offer line.
This lines are emphasized through the stemmed exterior mirrors, that are positioned on the beltline where they allow a better forward view to one side with their very narrow stems painted in the vehicle color. Their sophisticated aerodynamics also aids to keep along side it windows practically dirt-free, while ensuring a low level of wind noise.
Muscular hind end
At the rear, the eye is drawn to the integrated spoiler lip and wide tail light clusters. For that first time, the tail lights with their pronounced horizontal design are living in all-LED knowledge. Their upper edge extends forward into the sides, culminating in the feature line. A twin exhaust system with trapezoidal tailpipes rounds off the muscular outline.
Premium materials and stylish sportiness
Despite essentially the most compact dimensions in its class, the 2012 SLK has generous interior width. To achieve this, the designers have developed interior appointments that offer driver and passenger outrageous degree of quality and precision. Within is viewed as stylish sportiness and genuine high-quality materials which have been manufactured with perfect precision and skilled craftsmanship. Standard brushed aluminum trim covers the center console; wood trim could be ordered as an option in high-gloss brown lightly burl pine. Four round, metallic air outlets integrated ultimately dashboard emphasize that this model truly belongs towards Mercedes-Benz sports car family, their shape being nod individuals in the SLS AMG.
Echoing the exterior design, black friday 2010 dashboard emphasizes the lines of horizontal type and width of the vehicle. The SLK's generous round dials flank a display for the onboard laptop. The color display for the communications and entertainment functions is housed in the middle console and it is easily read by their driver and passenger.
An ergonomic multifunction sports steering wheel with a flattened bottom and thick leather rim makes the high quality and athletic character of brand new SLK an endless tactile get. Shift paddles and metal trim on the spokes add both sportiness and elegance. The interior can be enhanced farther with the Trim package which includes a wood/leather tyre and shift knob.
The sweeping lines among the upper dashboard section are continued in the door vanes. The center panel from the door is color-coordinated that's not a problem interior and also the door pulls and seat adjustment switches are trimmed in aluminum or optional wood.
Sporty yet comfortable seats
The sporty, ergonomic seats with adjustable crash-responsive NECK-PRO head restraints integrated in the backrests have high side bolsters for optimum lateral support and comfort on long journeys. Convenience and seating comfort is supplied by electric seat adjustment with memory functions and 4-way lumbar support.
The Mercedes-Benz SLK350 creates a choice of Black, Sahara Beige or Ash sun-reflecting leather as well as As well as white Bengal Red Premium sun-reflecting leather which noticeably reduces heat build-up. The leather has or even a coating which reflects the actual sun's rays and measurements have shown that decreases the temperature of the seats by more than 18 degrees Fahrenheit - a significant improvement in comfort as soon as the car been recently parked warm.
As ultimately previous model, the neck-level heating system AIRSCARF can be acquired as an optional extra for the actual SLK. This creates a flow of warm air around the neck and shoulder involving the occupants from a vent previously front every and every head restraining.
Attractive lighting
An ambient lighting system available for the first time as a choice in massive Package creates an impressive effect on the inside interior of your new SLK. It consists of discreet optical fibers in SOLAR RED, which produces a pleasant yet dramatic lighting effect the actual world door panels, around the entranceway pulls and also both sides of the very center console. This mood-enhancing ambient lighting is activated as soon as the doors are opened ('welcome home' effect), and its intensity can be individually varied by a dimmer.
The central interior lights are located the actual overhead control panel and includes two interior lights along with a center console spotlight. Additionally, a single LED is available in each A-pillar produce extra interior illumination on entry and exit.
The operating principle primarily based on the physics found in a plate condenser: if the glass structure is subjected to an electrical voltage, particles in brand new position themselves so that light is able to move through the wineglass. If the voltage remains switched off, however, the particles position themselves arbitrarily. This partially blocks the light, as well as the glass remains dark. The control unit and converter are integrated into the front section in the roof, along with the switch is in the overhead control xbox 360.
UV and infrared light are also effectively blocked in transparent mode, while insulation increases even more significantly and noticeably in darkened mode, thereby and helps to keep the temperature on interior parts such as armrests cooler by around 18 degrees Fahrenheit fairly conventional tinted glass.
Measurements using a device termed as a star pyranometer in Death Valley, one of the world's hottest places, impressively demonstrated the cause. This device measures the intensity of exposure to sunlight. With an open roof, the thermal load with the sun on heat of Death Valley reached 1000 to 1100 W per square multimeter. With the transparent glass roof it dropped to 200 W, and once the roof was switched to darkened mode with MAGIC SKY CONTROL, it dropped to 40 to 50 W - one 20th of this original value and below a 60 watt light bulb.
Modern headlamp technology and LED daytime running lamps
The Mercedes-Benz SLK350 is outfitted with horizontally arranged LED daytime running lights with four Leds. The new SLK can be optionally equipped with the Lighting Package which provides active and cornering light functions.
The active headlamp includes intuitive headlamp range control which automatically adjusts the angle for this light beam to changes in the car's attitude - for example pitching movements when braking and accelerating - or to accommodate alterations in vehicle loading.
The wide tail lights of fresh SLK feature full Leds technology somebody in charge of. This merely ensures an unmistakable nighttime design, likewise enables LEDs to shine with different intensities in specific regarding the tail light cluster, depending of their lighting provide. LED technology has other advantages: in comparison to conventional bulbs they smoke cigars around 4.15 seconds faster, and are using a considerably longer operating life-style.

Phenomenon of lamp is suitable for the square, residential areas, public green space and other special places.

Solar lawn lights are different from ordinary street lights. They use solar cells as the only source of power supply. Due to the current cost of solar cell components, it is necessary to use efficient light sources in order to reduce the cost of the entire system. LED is a kind of semiconductor light-emitting equipment that can efficiently convert electrical energy into visible light. In recent years, LED technology has made a leap High luminous efficiency, and very long lifespan, LED uses low-voltage DC for power supply, safe and low light source control cost, so that it is no problem to switch light and dark, and switch repeatedly. So do you know how long solar lawn lights can last for lighting in different climates? 　　1. How long can solar lawn lights last in a rainy climate? 　　 Solar lawn lights can be based on detailed application environment and conditions during consecutive rainy days. Customers need to design, generally when encountering successive rainy weather, they should also be satisfied with the lighting time of 5-8 hours a day; 　　2, how long can solar lawn lights illuminate in a sunny climate? 　　The lighting time of solar lawn lights can be based on the user The demand is set, which is directly related to the selection and ratio of solar cell components and batteries. Under the premise of determining the power of the light source, the greater the power of the selected solar cell components and the capacity of the battery, the longer the lighting time can be ensured, and vice versa. shorten. Standard system equipment should generally ensure 5-8 hours of lighting every day.

The heat dissipation problem of led street lamps has been plagued by developers in the led lamp industry. Nowadays, lamps and lanterns basically use aluminum alloy with inserts as radiators. The heat dissipation effect of this kind of heat sink is not ideal, and the heat sink usually reaches a higher temperature. The radiator industry, as a supplier of the street lamp industry, has specially developed LED street lamp radiators, combining the following aspects: 1. Break through the existing finned aluminum radiator with unsatisfactory heat dissipation problem. Existing ceiling holes Most of the lamps use finned aluminum as the heat sink. The heat dissipation effect of this type of heat sink is not ideal, and the heat sink usually reaches a higher temperature. 2. Use insulating and heat-dissipating plastic instead of aluminum alloy to make heat sink. South Korea has developed a kind of LED insulating and heat-dissipating plastic in 2009, which increases the heat radiation capacity by 4-8 times while keeping the heat dissipation capacity equal to that of aluminum alloy. The LED heat sink made of this heat dissipation material can greatly improve the overall heat dissipation effect. 3. Using the principle of liquid convection, a ceiling hole lamp with good heat dissipation performance is provided. The heat absorbed from the lampshade by the coolant in the liquid tank installed on the lampshade is used, and the coolant is used in two liquid storages with different heights. The natural convection between the tanks dissipates the heat absorbed by the cooling liquid from the lampshade, so that the lampshade of the ceiling hole lamp is well cooled. 4. It can be flexibly rotated and is easy to install. Because the cooling liquid convection pipe connected between the two liquid storage tanks has a bellows structure, and the bellows structure can be stretched and bent, it will not hinder the flexible rotation of the lampshade, and is also convenient installation.

What is the impact of LED street lights on the future development? Nowadays, governments around the world have advocated energy-saving renovation projects that replace traditional street lights with LED street lights, and advanced to the second and third tier cities, and then the intervention of 'smart lighting' strengthened the advantages of LED street lights. Make it possible to save energy -% on the original LED energy-saving technology, coupled with the help of EMC mode, accelerate the popularization of LED street lights. It is predicted that this year will be a period of global LED outdoor lighting replacement tide, and the number of global LED street lamp installations will double in the next year. Even so, its popularity has not been as expected, especially since this year's LED street lamp advancing speed is significantly lower than expected, and the growth rate has slowed down. Is it affected by objective factors such as the change of government and anti-corruption, or is it subject to subjective factors such as LED street lamp technology and market prices? The author interviewed Professor Liu Muqing from the Department of Light Source and Lighting Engineering of Fudan University to discuss the status quo of LED street lights and opportunities for future development. Non-standard LED street lights * the big bottleneck At present, road lighting is still dominated by high-pressure sodium lamps, and LED street lights have not really replaced it. In this regard, Liu Muqing said that from a technical point of view, LEDs are better than high-pressure sodium lamps. For example, the light efficiency of the whole lamp can reach lm/W or more. Ballasts can only reach -lm/W at most. The luminous efficiency of LEDs has significantly exceeded that of high-pressure sodium lamps, and from the perspective of price and cost, LEDs are not much higher than high-pressure sodium lamps. Although from a technical perspective and market price point of view, LED street lamps are not inferior to high-pressure sodium lamps, but its popularization still needs a process. Specifically, it can be described from the following three aspects: 1. The luminous efficiency of LED street lamps is higher than that of high-pressure sodium lamps, which is only for technical reasons. In the market, the LED industry is currently in the early stages of development, and there are more poor companies than good ones. This part of the 'poor students' will cause the market to misunderstand LED street lights: 'LED street lights are not good.' Therefore, how to make people recognize and accept the quality of LED street lights still needs a process; Second, as the LED era continues to accelerate development, companies gradually realize the importance of product quality and continue to develop toward high quality. The quality of the overall market circulation products will Improve; Third, the issue of standardization. The traditional high-pressure sodium lamp, in simple terms, is composed of three parts: a bulb, a ballast and a lamp housing. The bulb is the most easily broken part, and its life span is about one year. Even if it is broken, it is very convenient to replace. Because it is a standardized product, it can be replaced by any manufacturer's bulb. On the other hand, LED street lights have different product specifications from different manufacturers. The same manufacturer needs to be returned for later replacement or maintenance of products. Indirectly, LED street lights have become a monopoly-bound product by enterprises. The irregularity of products is the biggest bottleneck in the way of LED street lights, and the establishment of standardized standards has become an urgent need for industrial development. If LED street lights solve the above problems, then high-pressure sodium street lights can fade out of the market. In theory, the promotion of LED on roads should be faster than indoor lighting, but due to the inertia of road lighting in the market, and the above standardization issues, its popularization effect has not been as expected. 'But I believe that there are **, street lights will be the spring of LED.' Liu Muqing expressed to the author his hopes for LED street lights.
