Here are some cold facts about lamps and lanterns, let's get to know them!
The Evolution of Bulb Lifespan: The initial incandescent bulbs had an average lifespan of only about 800 hours, which means people need to replace the bulbs frequently. However, with the continuous progress of technology, today’s bulbs, especially LED bulbs, can reach several thousand hours or even longer. This tremendous progress not only brings convenience to people’s lives, but also greatly reduces the waste of resources.
The Astonishing Temperature of Bulbs: You may not expect that when an incandescent bulb is lit, its surface temperature can be as high as 3000 degrees Fahrenheit (about 1649 degrees Celsius), which is much higher than the temperature of a steelmaking furnace. This also explains why incandescent bulbs become extremely hot after long-term use, and at the same time reminds people to pay attention to safety and avoid burns during use.
The Specialness of Energy-Saving Bulbs: Energy-saving bulbs (CFLs) often require a certain warm-up time to reach full brightness when just turned on. This is because its working principle is different from that of traditional bulbs, and it needs a process to establish a stable working state in the initial stage of startup.
The Secret of LED Colors Revealed: The reason why LED lights can emit a variety of rich and diverse colors is mainly because the light they emit has different wavelengths. By cleverly changing the structure and composition of semiconductor materials, it is possible to precisely control the LED lights to emit various different colors from warm red to calm blue, etc., so as to meet the lighting requirements of different scenes and needs.
The Lasting Record of the First Bulb: In 1879, the first commercial incandescent bulb invented by Edison surprisingly lasted for a full 13 hours. Compared with modern technology, nowadays some high-quality bulbs may continuously emit light for several years without interruption, and this huge progress reflects the leap in human lighting technology.
The Association between Bulb Color and Emotion: Different colors of light have subtle and significant effects on people’s emotions and mental states. For example, warm yellow light can often create a comfortable and relaxing atmosphere, making people feel warm and at ease; while the cool-toned blue light helps to improve people’s concentration and attention, which is very applicable in an environment that requires focused work or study.
The Technological Revolution of Smart Bulbs: Smart bulbs have become an indispensable part of modern smart home systems. They can not only be remotely controlled through mobile phone applications or voice assistants, but also set various specific lighting scenes, such as reading mode, party mode, sleep mode, etc., bringing great convenience and personalized experience to people’s lives.
The Truth about the Energy Consumption of Bulbs: Although the energy consumed by a single bulb itself seems not much, when considering the situation of a large number of bulbs used in many places such as homes and office places, they do consume a considerable amount of electricity. According to statistics, about 10% of the electricity consumption in the family is used for lighting, which also prompts people to pay more attention to the selection and use of energy-saving bulbs.
The Outlook for Future Lighting Technology: Scientists are actively researching more efficient, environmentally friendly and intelligent lighting technologies. For example, using nanomaterials to make more energy-efficient and longer-lived bulbs, or developing new lighting methods by imitating the principle of bioluminescence. These future lighting technologies are expected to further improve people’s quality of life and at the same time make greater contributions to global energy conservation and environmental protection.
