LED spot lamp lighting instead of traditional halogen lamp (two)

At present, the heat of the spotlight, if only 1W of the spotlight, then only need to heat the aluminum substrate can be, do not need to add another radiator. For the 3 to 5W lamp, often need to use heat, the heat dissipation shell composition usually has the following script: plastic shell with aluminum stamping, stamping aluminum shell, die cast aluminum, aluminum extrusion shell, ceramic shell, plastic aluminum shell structure.

Light source LED specification. There are 2835303056305050 LED package commonly used in the spotlight, usually according to the customer request to choose, if the customer does not have special requirements, we generally use 2835 words for flat lamp, lens of 3030. At present, the use of these two methods will be better.

In the past 10 years, LED has changed greatly in color, brightness and power. Especially in the improvement of light efficiency, as well as the cost of the decline, the current LED spotlights in the use of ordinary families has become increasingly common. Production of light source light efficiency from 08 years of 80lm/W upgrade to the current 140lm/W, and small power LED lamps prices from the previous $20 /W, down to 3 to $5 per watt. Makes the use of LED spotlights in home and commercial lighting is becoming more and more widely used. LED with its amazing and gratifying application in the city indoor and outdoor lighting plays the role of the traditional light source. LED life of up to 100 thousand hours, which means working for eight hours a day, you can have a free maintenance of the theory of protection for 35 years. Low voltage operation, up to high light output, dimming low to zero output, can be combined with thousands of kinds of light and color, and the light-emitting area can be very small, can be made into 1 mm2. After two times of optical design, lighting lamps to achieve the ideal light intensity distribution. The rapid development of LED technology will bring new possibilities for lighting design and application. The development of white LED technology promotes the progress of energy-saving lighting system.

At present, the LED spotlights are replaced by the traditional halogen tungsten lamp, which is limited by the requirements of its shape and installation, which makes the design of the LED spotlight difficult. In the standard range of the existing standard, it is difficult to make a LED spotlight to achieve the best high power and high luminous flux. At the same time with light, heat, electrical safety and other aspects are also facing many difficulties, can not reflect the long life of LED, Gao Guangxiao and other characteristics, is not conducive to the healthy development of LED lighting. LED itself is a new type of light source, LED spotlight is one of the first to reflect the characteristics of LED applications. Should be based on the characteristics of LED, a new set of specifications for the specification of LED spotlights. LED spotlights on the external dimensions, module block, parameter sub file, standard interface, etc., to achieve LED modular and interchangeability, thereby promoting the healthy development of LED lighting.

Now, the international ZHAGA alliance, which has attracted from the United States, Asia and Europe hundreds of lamps, light source, LED module manufacturers and related industries, has been in the specified interface standard to carry out LED lamps. Its commitment to strengthen the LED module and its control in the mechanical, testing, parameters and other aspects of compatibility. Relevant technical specifications have been published, some of which have been revised many times. In China, led by the national semiconductor lighting engineering research and development and Industry Alliance organized a number of large LED companies to carry out the relevant information technology integration, and strive to standardize the LED module more and more detailed specification. Make it possible to follow up for different parts of the damaged LED lamps exchange between different brands. Further energy saving and material loss reduction.

In short, with the LED technology continues to mature, Chen Ben continues to reduce, LED spotlight has been initially gaining popularity, has been widely applied to various occasions, but the development and popularization of LED lighting is also facing many problems. How to solve the problem of high power, high luminous flux LED lamp radiating ask day; how to realize the LED lamp modularity and interchangeability; how to fully embody the characteristics of LED long life, high efficiency, etc., so that people can enjoy the rich and colorful lighting, more affordable, more secure and reliable LED products also, we need to do more research and cooperation.
