As a widely used light source, LED is favored by users for its advantages such as high efficiency, energy saving, fast response and long service life. So, what technical parameters of LED should we pay attention to? Here in this article, we will explore some important technical parameters of LED, and learn about the main application fields of LED and the development prospects of LED.
LED, the full name of which is Light Emitting Diode, is a semiconductor electronic component that can convert electrical energy into light energy. It is made of compounds containing gallium (Ga), arsenic (As), phosphorus (P), nitrogen (N), etc., and can radiate visible light when electrons and holes recombine.
Color temperature: In degrees Kelvin (K), it indicates the color tone of the LED light source, such as 3000K for warm light and 5000K for white light.
Color rendering index (CRI): refers to the contrast percentage between the LED light source and the natural light source, ranging from 0-100%. The higher the CRI, the better the light source is at restoring the color of the object.
Kinglight XR Series1 & 1515RGBW LEDs offer over 90 CRI for the best color reproduction
Peak wavelength: The wavelength corresponding to the maximum spectral radiation power, mainly used for optical instrument identification.
Main wavelength: The wavelength corresponding to the color of the main light emitted by the light source that the eye can see.
These two parameters have an important impact on the selection and color performance of LEDs.
These technical parameters are crucial to evaluating the performance and quality of LED displays. Choosing a suitable LED display requires comprehensive consideration of multiple factors.
As an advanced solid-state light source technology, LED has a wide range of applications. The following are the main application areas of LED:
Display screen: LED display screens are widely used in advertising media, sports stadiums, stage backgrounds, municipal engineering and other fields due to their high brightness, high definition and long life. LED full-color display screens have become an important medium for modern information dissemination due to their large display area, stunning visual effects and personalized needs.

General lighting: LED lighting fixtures gradually replace traditional lighting sources, such as incandescent lamps, fluorescent lamps, etc., and are used in various fields such as home, business, and industry. LED lamps are widely welcomed by the market for their advantages such as high efficiency and energy saving, environmental protection and mercury-free, and long life.
Landscape lighting: In urban night scenes, building lighting, garden landscapes, etc., LED light sources have become an important means of creating beautiful night scenes with their rich colors, good controllability and energy saving.
Special lighting: Such as car lights, flashlights, mining lamps, etc., LED light sources have also been widely used in these fields due to their high brightness, low power consumption, and fast response speed.
LED indicators are widely used in various electronic devices, instruments and traffic lights due to their small size, low power consumption and long life. Especially in the field of traffic lights, LED lights have greatly improved the safety of road traffic with their advantages of high brightness, fast response and long life.
