Conclusion: Personalisasioŋ dafa wara méngoo ak li senaario bi làaj tegu
Material selection isn't a matter of single parameters; it's a systematic process based on factors such as brightness requirements (e.g., >8000 nits ci biti vs.<1000 nits indoors), environmental harshness (temperature, humidity, dust, vibration), and maintenance cycles. We recommend that users communicate in depth with manufacturers during the initial stages of customization, using methods such as finite element analysis (FEA) to simulate thermal distribution and salt spray testing to verify corrosion resistance, to ensure that the final solution achieves optimal performance while maintaining controllable costs.
