One thousand highlights the solid state lighting of the "amount" point

High brightness LED production process, device design, and integrated technology to promote the improvement of lighting LED performance and cost reduction. Cross formula, reradiating phosphors and all the lens structure to improve the efficiency of the role, the results can be obtained with the LEDs (box). If it is a high output white LEDs, the improvement of the spectral performance of the board to the general lighting of low maintenance and energy saving brings hope. According to the Semiconductor Lighting Industry Association chairman Yung S said: "Liu, PhD observed LED lamps unlike fluorescent lamps, LED fluorescent lamp does not contain mercury, more environmentally friendly than". The environmental advantage of solid state lighting lies not only in its composition but also in its operating efficiency. , OED designers and marketers to calculate the various factors to expand the scope of the actual application of solid-state lighting equipment and carefully observe the market acceptance. The fact that the end user's attention is more cost-effective than the life of the device. This is very different from the traditional lighting equipment, which makes the market value analysis is more complicated. The low operating and maintenance costs of a luminance LED, compared with those of tungsten and fluorescent bulbs, offset the high initial cost of the luminance LED, which is of great significance. The observation of an electronic data sheet is more convincing, and it shows that the idea of "price first, the other second" is hard to sell to the consumer market. High yield for the first time show complicated solid-state lighting and high output, the fact that there is no lighting accessories manufacturers realize lighting design of their heat treatment to ensure adequate convection beyond the tungsten lamp high operating temperature may cause the surrounding material without fire is caused by improper operation of people burn accessories. However, to make the brightness of the LEDs light output and operating life to achieve optimization, the premise is to install some of the cooling devices in the LEDs accessories. Otherwise, even if you win it's life, it will soon be found that LED is also the same as the traditional filament and fluorescent lights in the hardware store and homecenter shelves, can not stand out. Equipment is an important factor in market segmentation, such as machine automation, traffic control, signal lights, in these areas, high efficiency and long life can accelerate the pace of cognitive value. Began to wander if you hear someone with "early adopter" and "Automotive segment" the phrase is quite rare in the same sentence. But the brightness of LEDs for automobile makers but brought some notable advantages, although this equipment now is quite new, their fundamental advantages in part from the same principles and processes, to create their father generation and proved by brothers ---LED indicator series products. LED auto tail lights, emergency lights, car lights, brake lights and solves several intrinsic limit of tungsten lamp. The impact current of incandescent bulbs often makes circuit protection and fault detection work in trouble. The manufacturer must set up a fuse and a fault check start to adjust the amount of high current to the current and the duration of the current, so as to achieve no fuse damage and false positive fault detection. LED and tungsten compared to the existing vibration in amplitude and frequency range than tungsten strong, on behalf of the automotive experience. The size of the LED also allows the designer to design the appropriate lighting and shape in a smaller space, consistent with the overall design of the car. For example: replace the middle high position brake light (CHMSL) mounted on the rear deck.

(Figure1) many designers in the final to life under the LED definition, definition of LED is the ultimate life light output dropped to 50% of its original value. Excessive current and overheating temperature will shorten the life of LED. So many equipment manufacturers recommend OEMs to carefully control the energy sources of LED. This shows remarkable characteristics, in order to understand the LED in the middle high car brake lights or taillight assembly, body control module should control these devices under constant current conditions. However, Bill, an expert in the automotive market, explained that constant current design would complicate and trouble other lighting components and designs for the car. A constant voltage drive allows ICs controller occupancy to control mode, in this way, the fault inspection data is a must, in the same design, reducing external components, wiring between the fuse and the control module and the lamp box is necessary. Dezhou Automotive Mechanical Engineer Keith Wolford also said: "the [LED- control IC] provides one of the function is the fuse. If you have a LED drive box, then you have to transfer power to the fixed area, and install the fuse, because you already have a center lighting mode, you have to do is power supply to the lighting module arranged on the fuse. The diagnostic function of LED driver, if the lamp in one line short circuit, so you can use it without electronics protection to every one of the fuse box cover. An emergency application equipment LEDs height is as low voltage halogen lamps. Since a common low voltage halogen in a group shares a common power supply module, the LED- replacement system can benefit from a control circuit suitable for a light box. This method allows direct substitution and integrated installation. Company Zetex ZXSC310 is the LED-
