The advent of graphene bulbs is more energy efficient and has a longer lifespan than LED bulbs

In April last year, the National Graphene Research Institute of the University of Manchester in the UK developed a new graphene bulb. This new type of graphene bulb is still based on LED technology research and development. Its performance and service life are greatly enhanced through the magic graphene molecules, and it is expected to be cheaper than traditional LED bulbs in price. This innovative graphene bulb is a dimmable bulb with a filament shaped LED inside, and the outer layer of the LED lamp is coated with graphene. Graphene has a strong electrical conductivity, which can prolong the use time of the bulb and reduce energy consumption by 10%.

The research institute stated that the project was started in March 2015 and is currently focusing on the sales of graphene bulbs in an effort to keep them cheaper than traditional LED bulbs by reducing costs.

Adjustable graphene LED color almost covers the visible light spectrum

In July last year, a research team led by Ren Tianling, a professor in the Department of Microelectronics and Nanoelectronics at Tsinghua University, produced a new type of luminescent material from two different forms of graphene. For the first time, it was demonstrated in a graphene based luminescent system that using only one LED can adjust different colors of light, covering almost all colors of the entire visible light spectrum.

The tunable graphene LED developed by Ren Tianling's research team covers blue light at a wavelength of 450 nanometers to red light at a wavelength of 750 nanometers, with the exception of dark blue and violet. This groundbreaking research achievement not only achieves color fidelity, but also significantly reduces the number of light emitting units in display devices, thereby greatly optimizing the circuit and reducing power consumption. It is expected to have a revolutionary impact on display screens, lighting fixtures, and communication technology.

China's e-commerce is changing the urban landscape

China's e-commerce is changing the urban landscape. "Beishang Guangshen" is becoming "Beishang Shenhang". The decline of traditional trade will pull Guangzhou down, and the rise of cross-border e-commerce will help Hangzhou rise. In the future, the urban pattern of China should be "regulation in Beijing+financial operation in Shanghai+intelligent technology in Shenzhen+e-commerce in Hangzhou".

LED spotlights

LED spotlights

LED spotlights are spotlights that use light emitting diodes as light sources. Traditional spotlights mostly use halogen lamps, which have low luminous efficiency, relatively power consumption, elevated ambient temperature, and short service life. LED light sources are far superior to traditional lighting fixtures in terms of luminous principles, energy conservation, and environmental protection.
