Overview of LED bulbs

When it comes to lighting, people immediately think of the colorful and various lamps in lighting stores. Despite their diverse forms, the core part of lighting - the bulb - actually comes in three main types: incandescent, fluorescent, and gas discharge. However, this pattern will soon change, as a new star in the lighting field - the light-emitting diode (LED) bulb - is moving towards practical application. LEDs were invented in the 1960s, and in the following decades, their basic use was as indicator lights for electronic devices such as cassette recorders. To fully leverage the lighting potential of LEDs, scientists have developed new types of LED bulbs for illumination, such as the LED air vitamin clean bulb. This bulb features high efficiency and long lifespan, with a continuous use of 100,000 hours, which is 100 times longer than ordinary incandescent bulbs. It is estimated that globally, the LED bulb market has a potential worth of 9 billion pounds. Attracted by the huge business opportunities, some bulb manufacturers, such as Philips, have invested millions of pounds in research and development of household LED bulbs. Scientists predict that in the next five years, this type of bulb is likely to become the mainstream product for next-generation lighting. As we all know, for more than a century since American inventor Thomas Edison invented the incandescent lamp, people have basically continued to use Edison's technology to produce incandescent bulbs. The middle of the bulb is a metal tungsten filament, which emits light when heated to an incandescent state by an electric current.

The current status of LED energy-saving bulbs: LED lighting is still dominated by high-power white LED single bulbs. LED lighting fixtures are collectively referred to as LED lamps. With the further maturity of LED technology, LEDs will achieve more and better development in the field of residential lighting fixture design and development. In the 21st century, residential lighting fixture design will be dominated by LED lighting bulb design, fully reflecting the lighting development trend of energy saving, health, artistry, and humanization, and becoming the dominant trend in residential lighting culture. In the new century, LED lighting bulbs will surely illuminate everyone's living spaces, change everyone's life, and become a great revolution in lighting fixture development and design.

Traditional incandescent lamps (tungsten filament lamps) consume high amounts of energy and have a short lifespan. In the context of global resource scarcity, they have gradually been banned by governments worldwide from producing LED bulb series (19 photos). The replacement product is electronic energy-saving lamps. Although electronic energy-saving lamps improve energy efficiency, they use many heavy metal elements that pollute the environment, which goes against the general trend of environmental protection. With the rapid development of LED technology, LED lighting has gradually become the second choice for new green lighting. LEDs are far superior to traditional lighting products in terms of light-emitting principle, energy saving, and environmental protection.

As incandescent lamps and electronic energy-saving lamps still occupy a very high proportion in people's daily use, in order to reduce waste, LED lighting manufacturers must develop LED lighting products that are compatible with existing interfaces and people's usage habits, so that people can use the new generation of LED lighting products without replacing the original traditional lamp bases and wiring. Thus, LED bulbs came into being.

LED bulb lights adopt existing interface methods, namely screw and socket types (E26, E27, E14, B22, etc.), and even mimic the appearance of incandescent bulbs to conform to people's usage habits. Based on the unidirectional light-emitting principle of LEDs, designers have made changes to the structure of the lighting fixtures, making the light distribution curve of LED bulb lights basically converge with the point light source characteristics of incandescent bulbs.
