Everlight Electronics will exhibit high-efficiency intelligent display LEDs at 2012 LED EXPO INDIA
India, one of the BRICS countries, is a rapidly changing and rapidly developing market. Especially in the LED market, the demand for various applications of LED light sources has shown a high growth every year in recent years. The international LED packaging company-Evantech is going deep into the Indian market to improve its services to local customers. Especially at the "2012 LED EXPO INDIA" exhibition from December 14 to December 16, 2012, it exhibited brand new LED packaging for the Indian local market. Products: including a variety of new lighting components and practical products, automotive application components, infrared sensors and smart LED touch panels and other products, with nearly 30 years of professional experience, providing local customers from a single component to integrated modules Solution, service customers to find the most suitable corresponding products.
Everlight has introduced a variety of new high, medium, low power and integrated package (COB) components specifically for the LED lighting specifications required by the local lighting market: including a new 3020S package that can drive amperages at a super speed, small size and high brightness The new 2323 and 3535 package components, as well as various sizes and watts of polycrystalline integrated packaging (COB): Ju (Ju) series components, provide customers with different types of selection from 0.06W to 25W or more, so that LED lamp designers can follow Different lamp sizes and brightness requirements, among the Everlight products, find the most suitable and cost-effective (Lm / $) LED package components. In addition, Everlight exhibited low-power PLCC packages including 3528 and 3020, medium-power PLCC packages of 5630 and high-power ceramic packages of 3535 and 3045. Recently, the actual test by the certification body has passed the LM80 standard. This test result Will provide users with reliable and credible reference standards to choose the right Everlight LED lighting component products. In addition, Everlight also cooperates with local customers to display a variety of products that use Everlight LEDs, making it easier for visitors to understand the application of various lighting components.
The EU announced in 2008: Starting from February 7, 2011, all small trucks and passenger cars must be equipped with daytime running lights (DRL) to reduce the incidence of car accidents during the day. Everlight understands that the majority of car owners need a stable, bright and energy-saving daytime running light source, so they launched a high-power "Blink D" LED series at the India Exhibition. This series can provide fast light source response and high-luminance luminous performance. In addition, the "Shuo D" series has passed the high-end certification of the product side AEC-Q101 and the manufacturing side TS-16949, and has been recognized in terms of quality performance and safety.
At present, most smart mobile communication products on the market usually have built-in IR, light-sensing and distance-sensing components to adjust the screen brightness, brightness and darkness, and automatic display to achieve the energy-saving effect of the product. In the design of sensors, manufacturers usually implant them as separate components, which will occupy a considerable amount of space on the circuit board and cannot achieve the goal of reducing the size of the product. In view of the inconvenience of customer design-in, Everlight has designed a powerful new 3-in-1 sensing module: APM, which integrates IR, light source and distance sensing functions, which can reduce the components of customer design-in Quantity, flexible use of the remaining space on the circuit board, giving product design more freedom and change.
In response to the terminal display functions required by the consumer market, Everlight has launched a new smart LED display panel: ELMM-457. This panel can be used for display functions such as electronic fitness equipment and POS retail and wholesale systems. It has built-in IC devices and 104 characters, and reserves 24 characters for client design. It can be displayed separately or connected to several panels at the same time. ; Allow clients to retain more diverse changes in hardware design changes.
In addition, Everlight also collaborated with local customers in India to display bus signs using Everlight's high-brightness inline LEDs, so that visitors can more easily understand the suitable applications of various LED components. Everlight emphasizes diversified R & D and design of LED components with diverse applications, providing customers with "one-stop" diversified product solutions. Regardless of various applications, Everlight's service concept of "selecting suitable LED components according to the time" can meet the needs of customers in all aspects. At the same time, Everlight will continue to develop various high-efficiency LED energy-saving products, replace traditional light sources with new LED light sources, reduce electricity consumption and reduce carbon dioxide emissions; to achieve the goal of environmental protection, Everlight Electronics is committed to working with customers to create a green new future.
There are two types of noise canceling headphones, active noise reduction and passive noise reduction.
The active noise reduction function is to generate a reverse sound wave equal to the external noise through the noise reduction system, and neutralize the noise, thereby achieving the effect of noise reduction. Active noise canceling headphones with noise-reducing circuits that compete with external noise. Most of them use a large head-mounted design, which can be used to block external noise by using earplugs and earphone casings, and to perform the first round of sound insulation. There is plenty of room to install active noise reduction circuits and power supplies.
Passive noise canceling headphones mainly form an enclosed space by surrounding the ear, or use soundproof materials such as silicone earplugs to block external noise. Since the noise is not processed by the noise reduction circuit chip, generally only high frequency noise is blocked, and the noise reduction effect on the low frequency noise is not obvious.
Application:
1: Business people, because of frequent business trips, especially those who travel between different cities every day, they must hate the noise in the cabin. If there is a noise-cancelling earphone, they will be able to stay away from these noises. Relax by enjoying the music.
2: The office staff also need a pair of noise canceling headphones. Sometimes when thinking about planning, listening to the sound of central air conditioning is particularly annoying, and if there are colleagues around at this time, it is even more annoying. At this time, you may wear a pair of noise-cancelling headphones to expand your thinking in music.
