Advantages and disadvantages of high power LED lighting lamp

High-power LED is one of the most important means to achieve high flux. High power LED lighting has many advantages, there are also disadvantages. How to make good use of high-power LED is the key, while for high-power LED lighting products and traditional lighting products were compared, but also high lumen LED lighting in the area of the discussion.
First, the history of the development and application of LED LED has the potential to increase the brightness of every 10 years, from birth to 30 times, 10 times the price drop "Haitz" law of rapid development. Ordinary high-brightness white led laboratory currently has reached the level of 100lm / W's, 50lm / W high-power led high bay light price has entered the commercial. In terms of monochromatic light, red, yellow, blue, green light effect is being constantly refresh the record, LED light source as a new range of applications more widely, has gradually attracted more attention and expectations.
Currently LED applications with diversified distribution in various industries, including directions, display, backlight, lighting and so on. LED lighting is the most potential for many applications in the industry, with the lower LED light continuous improvement and cost efficiency, which is in the possession of the entire lighting market will be growing. Following the United States, "the next generation of lighting plan," Japan's "21st Century Lighting Plan", the EU's "Rainbow Project" and South Korea's "solid-state lighting plan" was established in 2003, China National Semiconductor Lighting Project Team, aims to integrate resources, fast forward to enter the LED lighting market. According to the Chinese Academy of Engineering academician Liang-Hui Chen predicted that China between 2005 and 2015, the semiconductor lighting cumulative saving 400 billion kWh of electricity, saving electricity costs for users of 260 billion yuan, 150 billion yuan output value creation, to solve the employment one million population.
By then, the semiconductor lighting energy savings will exceed the annual "Big Mac" - the annual generating capacity of the Three Gorges power station! In the context of the growing shortage of energy, the use of LED energy-saving features, the development of LED lighting is the positive response to the construction of a conservation-oriented society of the Government.
Second, the high-power LED characteristics and compare with other LED light source is known as the "green light" deserved. In the lighting industry, the comparative analysis with traditional light sources exhibit some aspects irreplaceable advantages: LED as a light source for illumination has the following advantages:
1. Low power consumption: luminous efficiency of 75lm / W of LED power consumption than equivalent incandescent brightness reduced by about 80%;
2, long life: the product life of up to 50,000 hours, 24 hours of continuous light can be used for seven years;
3, the dynamic control of brightness and color easy: You can achieve continuously adjustable brightness, high color purity, enables dynamic color conversion and digital control;
4, flexible dimensions: organic can be achieved with the construction of integration, to only light but not light;
5, environmental protection: no toxic metals mercury, no infrared and ultraviolet radiation;
6, color: bright saturated, pure, without filters, red, green and blue elements available to tune into a variety of colors, can be varied to achieve, by changing, mixing light effects, color with excellent results. Set so many advantages in one, made us feel strongly promote the use of LED is a valuable work.
However, comparison of led high bay light for sale and other light sources are also inadequate aspects, such as the color of the white light illumination is low. Currently yellow and blue phosphors to produce white LED, its color index of about 80. As a general lighting can be, but for some color spaces that require high resolution becomes insufficient. Although the red phosphor by adding the appropriate methods, you can make up to 90 CRI or higher, but compared with incandescent 99 still has some gaps, and its efficiency is affected. By RGB color mixing treatment can also improve color rendering, but the technology needs to do more work on the universal application, so in terms of color, LED still needs to be improved. As for the price is too high, one-time investment is large, in fact, from a comprehensive cost considerations, many occasions to use LED or significant cost savings.
