Although the LED is a current device - led power 10w is no exception, but the car tail lights, brake, turn signal lighting applications can still benefit from the voltage drive structure.
Efficient LED available, retail and residential LED interior lighting may soon appear. LED manufacturers have only just begun to address the high color temperature light source.
The high brightness LED manufacturing processes, device design and assembly technology progress, the LED luminous performance has been improving, the cost has been in reducing the speed of performance enhancement and cost reduction are memorable. PN junction design, re-radiation of the phosphor and a lens structure to help improve efficiency, and therefore help to improve the availability of light output. For high-output white led 1w wide spectrum performance improvement makes low-maintenance energy efficient light source for general lighting hope.
Comparable with standard fluorescent LED efficiency will take some time, but as the Semiconductor Lighting Industry Association Chairman Yung, S. Liu, said: "LED light is also more environmentally friendly products, because it is not the same as with fluorescent, do not use mercury.
The environmental advantages of solid-state lighting, composition and efficiency is not the primary market-driven factors, but it does make this technology and its suppliers have a good image.
At the same time, work in various fields of OEM designers and marketing staff has been in expanding the practical application of solid-state lighting, and has been closely watching the market acceptance. However, the final cost-benefit of the users within the solid-state lighting equipment life experience is not the same, which is very different with the traditional lighting. The fact that market values change complicated. Compared with incandescent light bulbs and fluorescent lamps, high brightness led power 50w use of cost and maintenance costs are much lower, which can offset the higher initial cost of LED. Although the above discussion may be very attractive, but make it in the "price, on the other ideological tendencies dominate the consumer market a lot of marketing difficulty.
The light fixture manufacturers has always been in their design does not consider the thermal management of the bulb, just enough convection to ensure that the high operating temperature of the tungsten does not bring the danger of the surrounding material to fire danger or fixture operator burns. Complicated by the fact that mass production of high-output solid-state lighting. However, if the final design is the best to make the LED light output and lifetime, high brightness LED fixture you need a certain amount of thermal design.
Therefore, although not soon see the high-brightness LEDs to traditional tungsten or fluorescent light from the shelves of hardware stores and home centers, crowding out, but these devices are to enter the market segments of automobiles, traffic control, external signs, because In all these areas, high efficiency and long life of the lamp will increase the value of the obvious.
High Brightness led 10w cut outcrop angle
In fact, the "early adopters" and "car market segment," two phrases rarely heard in the same sentence. Some may assert that this set will be popular in the oxymoron. However, high brightness LED for car manufacturers several compelling features, and, although relatively new, but the majority of their basic characteristics comes from the manufacture of LED indicators - they are much older and good proof of a similar product - the same principle and similar processes.
High Power LED 50W car taillight, turn signal lamps, work lights, brake lights can be overcome several major tungsten incandescent inherent shortcomings. The cars often subject to moderate shock and vibration will shorten the filament life. Similarly, the transient inrush current caused by the filament resistance of positive temperature coefficient will accelerate the destruction of the bulb. The thermal loop - an important feature of the brake lights work, tend to shorten the incandescent lamp life.
Incandescent bulbs of the transient inrush current circuit protection and fault detection task to change complicated. The car manufacturers must fuse rating and fault detection threshold is set to a sufficiently large current values, to adapt to the inrush current magnitude and duration, fuse blown fault or does not detect false failures will not occur.
