Working principle of SMD LED diode
Semiconductor luminescence
When current passes through the P-N junction, electrons and holes recombine to release energy and convert into visible light of a specific wavelength. The wavelength determines the color of the luminescence (such as 460nm for blue light and 620nm for red light).
SMD package conductivity
The metal electrode is connected to the circuit through the pad, and the current is injected into the chip through the electrode to realize the conversion of electrical energy to light energy.
Heat dissipation control mechanism
The package substrate uses high thermal conductivity ceramic or copper material to quickly conduct the heat generated when the chip is working to avoid overheating affecting performance.
Light efficiency enhancement design
The chip surface is covered with phosphor (such as white light LED), and multi-color light output is achieved through wavelength conversion to improve light utilization.
fAQ
1. Is there a big difference in brightness between SMD LED diodes of different sizes?
Brightness is related to chip power and size. At the same power, slightly larger size has better heat dissipation. The brightness deviation can be controlled within ±5%, and can be selected on demand.
2. Can products with specific wavelengths (such as ultraviolet and infrared) be customized?
Customization of products with a wavelength range of 365nm-940nm is supported, sample testing is provided, and the batch production cycle is about 15 days.
3. Will the components be damaged by excessive temperature during welding?
Withstand the peak welding temperature of 260℃/10 seconds. It is recommended to use the reflow soldering process. Controlling the temperature curve can avoid damage.
4. What are the effects of the working current exceeding the rated value?
Exceeding within 10% can work for a short period of time. Long-term excess will lead to accelerated light decay and shortened life. It is recommended to use it according to the rated current.
5. What quality inspection reports are there for bulk purchases?
Provide spectral analysis, luminous flux, color temperature and other test reports, comply with RoHS and REACH environmental standards, and support third-party testing.
