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 component on the other hand.
LED chips are pure semiconductors without substrate, encapsulation material and possibly optics. The contacted chip is the actual light-emitting source.
If the chip is contacted on a carrier (ceramic, FR4, pre-molded leadframe...) and then encapsulated, so to speak built into a package, then we speak of a LED component. The component is the finished part, which can then be soldered onto a circuit board.
These high current dice can be driven at very high currents compared to the chip size, thus an outstanding cost vs.performance ratio can be obtained. The compact chip architecture delivers a high optical power density for lighting applications that require an intense lighting output. The combination of RGB allows innovative lighting designs. We also offer special wavelengths in UV for disinfection applications.
Features
- Highest luminous and radiant powers per 1mm² in the market
- Biggest current density up to 3A/mm²
- Available at 390 nm, 435 nm, 455 nm, 527 nm, 620 nm
- Die size around 40 x 47 mil²
- Only 5 mil thickness -> optimized thermal properties
- Highly optimized current distribution across the die
- Side bondbar -> Possibility of using more than 1 bondwire
- No bondwire in the optical emission window -> no shadowing
- Surface emitting dice -> optimum for optical coupling
- Gold backside -> possibility of Ag sintering
- UV, blue and green dice have the same design, red is different
- Maximum applicable current: 3A
Applications:
These LED chips are useful in a braod range of applications. Especially the idea of packing a high light densitiy in a RGB combination into a suffiicient housing makes this product a smart solution for lighting and projection applications. The LED chip in the lower UV range can be efficiently used in medical applications.
Further target applications are: Medical, spectroscopy, projection, automotive illumination, general lighting, design illumination, stadium lighting, specialty lighting, position lighting, disinfection systems, sterilization
