Then, let's talk about the commonly used LED chips for general small lights, turn signals, brake lights, and reverse lights:
3014 Chip:
First, the lowest-tier chip: 3014, with a side length of 3.0mm x 1.4mm.
⭕: Cheap, so cheap that it makes you doubt...
❌: Low brightness, short lifespan, poor heat dissipation—basically, it has all the drawbacks you can think of.
4014 Chip:
3014 was upgraded to 4014, with a side length of 4.0mm x 1.4mm. Both brightness and durability have been improved, but PA still lacks confidence in its actual use.
⭕: 2 times brighter than 3014, and durability has also improved.
❌: Not heat-resistant. Although heat dissipation has improved, it is not recommended to use too many chips in accumulation.
5050 Chip:
The 5050 chip is a long-lasting and widely-used chip, with a side length of 5.0mm x 5.0mm. It has been in the market for over 10 years, and its prevalence is no surprise.
⭕: The technology is mature, and 5050 chips produced by high-quality manufacturers exhibit high stability.
❌: The technology is not advanced, and there are often low-quality products on the market, resulting in significant variations in performance.
High brightness and are often used in headlight applications.
3528 Chip:
With a side length of 2.5mm x 2.8mm, the 3528 chip relies on its own chip for heat dissipation and is, therefore, unsuitable for high-power applications. However, it offers high stability and is a suitable choice for positions where high brightness is not required, such as dashboard lights.
⭕: High stability.
❌: Low brightness, low heat dissipation efficiency.
2835 Chip:
The 2835 chip is very similar to the 3528, but the difference lies in the packaging process technology. Additionally, the 2835 chip is thinner and adopts a through-hole heat sink, resulting in even higher stability. Moreover, its brightness and power capacity are more than double that of the 3528 chip, making it widely used in various bulb positions.
⭕: High brightness, high stability, can handle higher power.
❌: It requires more sophisticated technology, testing the circuit design.
Widely used in automotive lighting due to their versatility.
2525 Chip:
It has a similar appearance to CREE chips and offers the same multi-angle emission effect. Each chip has a brightness of up to 140LM and a power of 3W, resulting in an overall excellent performance.
⭕: High stability, uniform emission angle, and high brightness.
❌: The unit cost is high.
🤷♂️What to Consider When Buying LED Products?
When purchasing LED products, it is essential to pay special attention to the intended application and usage. Consider whether the product will be continuously illuminated for extended periods and whether high brightness is necessary.
Selecting the appropriate product and LED chip based on your specific requirements will ensure optimal performance and cost-effectiveness, allowing you to achieve the best results while saving money.
