LED lamp beads light-emitting diode principle and electrical parameters
LED is taken from the abbreviation of LightEmittingDiode three words, the Chinese translation is "light-emitting diode", as the name suggests, light-emitting diode is a kind of electronic device can be converted into light energy with diode characteristics.
LED tube - characteristics and application
LED: Light Emitting Diode, a solid-state semiconductor device capable of converting electrical energy into visible light, which can directly convert electricity into light LED energy-saving lighting the basic features
Researchers develop retractable LED device that can act as a temporary tattoo?
Recently, a team of researchers at Nanjing University reportedly developed a retractable LED device that conveys information and can be attached to human skin and other surfaces. The LED device, which acts like a temporary tattoo, works at low voltage and therefore does not cause harm to the user.
2020 Global LED Display Market Outlook - Corporate Meetings, Sales Channels and Price Trends
According to LEDinside's latest report - 2020 Global LED Display Market Outlook - Corporate Meetings, Sales Channels and Price Trends, with the increasing demand for LED displays in high-end retail, conference rooms, movie theaters and other niche commercial display markets, the compound annual growth rate is estimated to be 14% from 2019 to 2023. With the continued fermentation of the future super small pitch trend, the compound annual growth rate of LED small pitch display is estimated to reac
What's wrong with light-emitting diode leakage?
First of all, do not mix the leakage current of light-emitting diodes and power or lighting leakage. When you connect the light-emitting diode to the DC power supply, and then the two pins of the light-emitting diode in reverse, at which point you will find that a connection light
LED plug-in diode lighting is moving towards intelligence!
With the deepening of corporate cognition, for different places of use, companies will be the human demand for plug-in diodes also studied more thoroughly: for example, in the commercial lighting category, the color temperature to 4000K or less, color rendering index to 80 or more, to be able to well illuminate the texture of the product; in road lighting, outdoor warm white lighting effect will be more popular, and the safest and clearest vision in warm white light, warm white light ( 2800K) or
Talk about how LED light suppliers solve the problem of heat dissipation!
LED is known as the fourth generation of lighting light source or green light source, with energy saving, environmental protection, long life, small size and other characteristics, can be widely used in a variety of instructions, display, decoration, backlight, general lighting and urban night scene and other fields. In recent years, the world
Infrared manufacturers have come up with the top ten effects of far infrared rays on the human body!
Infrared manufacturers have concluded that far infrared is a kind of light that is beneficial to the human body and is the light of life. Far infrared light is not harmful to the human body, even if it radiates high temperature of tens of degrees, the human body can still accept it. The resonance effect, soaking effect and warming effect of far infrared light on cells are widely used in the health care and health industry.
Healthy lighting has always been a problem for people and LED suppliers
LED beads healthy lighting has always been a problem that people and LED light suppliers focus on, from once no strobe, no radiation, to now the full spectrum of LED beads, people's definition of "healthy lighting" has been changing, at this stage, as the full spectrum of LED beads has become the "key" to healthy lighting, a key technology around, why is the full spectrum of LED beads so important to "health"?
LED suppliers knit out the basics
LED skills throughout: LED lighting value of the power crisis, the greenhouse effect and the growing deterioration of the ecological environment when reminding people that the Earth is now exhausted, changing the way people get power and improve the use of power has become the current world consensus.
Basic knowledge and application of plug-in diodes
The main parameters of diodes: forward current, forward voltage drop, reverse breakdown voltage, reverse leakage current, junction capacitance, etc.
Outdoor LED display is a city card in the new era
In recent years, outdoor LED display shows a high-speed development trend, outdoor LED display brings the unique communication value of other traditional outdoor media, has become the business card of many cities in the new era, and act as a showcase city business
