Although the proportion of lighting energy consumption in the overall energy consumption of a data center is not high, people tend to ignore it. With the maturity of energy-saving light bulbs and LED lamp technology, people have more choices, and more and more attention is paid to the lighting energy saving of data centers. Although the industry is currently focusing on the research and development of alternative energy sources, or taking energy conservation as an important goal, how to "use less" while "creating more" energy is also a big challenge.
Since the automotive industry is driving energy savings and cars are a major source of energy consumption, hybrid vehicles (HybridVehicles) have gained reasonable attention; and household and commercial lighting also consumes a lot of energy, roughly accounting for 30% of overall energy use. Around 15-35% (depending on which unit's statistics you trust more). The "hard work" incandescent light bulbs have been around for many years and are still widely used, but their poor energy efficiency -- often below 5 percent -- needs to be improved.
There are two emerging lighting technologies, including the so-called energy-saving light bulbs (CompactFluorescentLamp, CFL), and LED lamps, has begun to contribute to energy conservation, and market power is gradually expanding. In the past, these two lighting products were very expensive, but now the energy-saving light bulbs on the market cost less than $5, which can replace ordinary incandescent light bulbs.
In addition to energy-saving light bulbs, LED lighting has gradually become an acceptable alternative to incandescent light bulbs in the market at a steady pace. Recently, an eye-catching high-brightness LED projection lamp has been launched; this article will analyze the above two products.
In fact, fluorescent bulbs are inherently more efficient than incandescent bulbs, producing more direct light per watt of electricity and generating less heat. Fluorescent tubes have been used in offices, shopping malls and residential environments for a long time, but they are not suitable for replacing small lighting fixtures due to the limitation of the shape of the tubes. Until the 1980s, miniaturized energy-saving light bulbs began to appear on the market, and the price was getting lower and lower, which was increasingly acceptable to consumers.
The 20-watt MaxLite energy-saving bulbs used in this teardown analysis are claimed to be comparable in brightness to 75-watt incandescent bulbs; this product, like traditional fluorescent (daylight) lamps, uses UV rays that block the ionic gases inside the bulbs Radiant interior phosphor-coated glass body. Current energy-saving light bulbs achieve miniaturization through spiral and folded shapes (U-shaped). In order to be able to be used in general desk lamp sockets, energy-saving light bulb products including MaxLite brand also use a miniaturized bulb head design.
