LED chips over a broad wavelength spectrum


For white LED chips, we do not speak of wavelength ranges, but of color temperatures, typically specified in Kelvin for white. The warm white temperature is 2200K or 3000K, neutral white is around 4000K, followed by cool white from 5000K. White LED chips and components are mainly known from general lighting applications such as spotlights, luminaires and lamps. For luminaires, the unit in lumens is a measure of how much light a light source emits. The unit watt, on the other hand, indicates how much electrical power is consumed. Lumen to watt is thus a measure of the efficiency of a light source. In addition to the applications already mentioned, white LED chips can also be used as indicators in industry. A high proportion of warm white LEDs can still be found in lamps for general lighting.

The UV wavelength range extends from about 100 nm to 400 nm and is significantly higher in energy compared to the visible range of light. Indium gallium nitride (InGaN) has proven suitable as LED semiconductor materials for generating long-wave UV radiation around 400 nm, and aluminum gallium nitride (AlGaN) for short-wave UV radiation. The wavelength of UV radiation from UV LEDs is typically between 400 nm and 250 nm. Interesting application fields are exposure, spectroscopy, curing, printing, coating, medical instruments, industrial imaging, disinfection systems, sterilization, chemical and biological analysis, UV inspection systems.


Blue light not only glows blue, but is an integral part of the color spectrum. Without blue, there is no white.
Blue-emitting LED chips based on indium gallium nitride (InGaN) are combined with a yellowish luminescent layer (converter) located in front of the LED chip, which acts as a wavelength converter, resulting in a white-emitting LED.

Another method to achieve white light is to mix red, green and blue as additive color mixing. Since red and green LED chips were available first, they alone could not be used to produce white LED light. With the development of blue, the third basic color is available. Now the three colors can be overlapped to white light, the RGB mixed white.
Thus, 2 fundamentally different methods are available to generate white light: blue with converter and RGB mixing, which are more suitable depending on the application.

General application fields of blue LED chips are general lighting, projection, high current operation, architectural lighting, outdoor lighting, sensing and many more...


Cyan or turquoise LED chips or also called Verde, are like the blue LED chips from the material group InGaN. Due to their properties, just like blue LED chips, they are particularly suitable for applications in medicine, lighting and displays or also for backlights. Cyan is particularly suitable for improving the color quality of white. This requires an LED package in which several chips in cw/ww/cyan/red are integrated.


Like the white and blue LED chips, green LED chips are from the InGaN material group. Their properties make them particularly suitable for applications in medicine, lighting, backlights or displays. Green light sources in particular are used in smart watches with a function for measuring vital signs and thus also have many potential applications in sensing technology.


Yellow LED chips from the aluminum gallium indium phosphide (AlInGaP) material group are particularly suitable for applications in medicine, lighting for luminaires and displays, backlights and in the automotive sector for one of the main applications in turn signals.


At the latest with the mass production of red LEDs in the 1970s, the advance of this technology into many applications could no longer be stopped. All other developments around the wavelength spectrum are based on this foundation. Red LED chips or LEDs are widely used in automotive lighting, general lighting, architecture, indication lighting, sensor technology, ...


The range of non-visible light plays a decisive role for sensor technology. IR LEDs are used in simple data transmission systems such as infrared remote The range of non-visible light plays a decisive role for sensor technology. Original areas of application for IR LEDs were in simple data transmission systems such as infrared remote controls or the infrared interface IrDA. Other areas of application include alarm and security technology, for example in light barriers, motion detectors, night vision devices and surveillance cameras, cell phones, encoders, precise length and angle measurement, MachineVision, Industry 4.0, robotics, mechanical engineering.

Frequently asked questions

LED Chip

What is a LED chip?

We at Chips 4 Light work with optoelectronic semiconductors and distinguish on the one hand in LED chips or as a synonym for chip bare die, die or dice and LED components on the other hand. LED chip defines the pure semiconductor without substrate, encapsulation material or optics. The contacted chip is the actual light emitting source. The LED chip is a semiconductor crystal consisting of layers of differently doped semiconductor materials.
In one semiconductor layer there is an excess of positive charge carriers, while in the other layer the negative charge carriers are in the majority. The chip is installed in a package. This so-called LED package leads the electrical contacts to the outside and contains the conversion layer (phosphor) for generating white light. The package also accommodates other functions, such as protective circuits, optical lenses or elements for heat dissipation.

LED Component

What is a LED component?

If the chip is contacted on a carrier (ceramic, FR4, pre-molded leadframe...) and encapsulated, installed in a housing, then we speak of an LED component. The component, called a light emitting diode, is the quasi finished component, which can then be soldered onto a circuit board or built into modules or luminaires. Here, various parameters such as heat generation in the component, radiation characteristics, luminous flux, ... must be taken into account to ensure that the service life of the diode is not negatively affected. We are happy to advise you on the correct handling or packaging of LED chips and on the development of chip on board (COB) solutions, SMD or radial components.

Chip, SMD or Chip on Board

Only a LED chip, SMD or chip-on-board (COB) device?

The unmouned LED chip allows, among other things, to keep the design very small or to realize different functions on one board by combining several chips in, for example, RGB modules. Do you have to fulfill one or all requirements with your applications? We meet your challenges with an extensive LED chip portfolio for specific applications in high-resolution sensor technology or medicine. The focus is on miniaturizing the light source to keep the complete system as small as possible. Regardless of these applications, our portfolio includes LED bare dice that are designed for
