1. Heat dissipation:
   • Analysis:The metal shell has good heat dissipation performance, which affects the service life of the lamps. Importers should pay attention to the effectiveness of heat dissipation to achieve reliable and long-lasting performance.
2. Frame Material:
   • Analysis: Importers need to be aware of the quality and price differences between aluminum frame and plastic frame. The quality of materials affects appearance and performance, and the balance between quality and cost must be considered.
3. Use of floodlights in outdoor environment:
   • Analysis: The importer must be aware of the environmental conditions in which the lamps will be placed, and it is preferable to use a metal frame in difficult weather conditions outside buildings.
4. Cost control and material quality:
   • Analysis: Importers must be careful in determining the balance between cost and quality of materials. Reducing the cost of parts can reduce product quality and increase the rate of complaints from consumers, so emphasis should be placed on quality in electronic processes in particular.

The reflector (reflective cup) plays a crucial role in effectively directing light and improving the optical performance of LED lamps. There are two common types of reflectors: metal and plastic.

1. Metal reflector:
   • Advantages:
     • Low cost.
     • Temperature resistance.
   • Defects:
     • Requires sealing and gloss.
     • Retains deformation memory.
     • Popular in low temperature lighting applications.
2. Plastic reflector:
   • Advantages:
     • High visual impact.
     • No memory distortion.
     • It includes complex processes such as plastic forming and coating.
   • Defects:
     • Moderate cost.
     • It is used in high quality lighting requirements with medium temperatures.

Based on this analysis, a metal reflector can be used for low-temperature lighting applications, while a plastic reflector is a suitable option for meeting high-quality, moderate-temperature lighting requirements. Importers should consider these characteristics and the actual needs of the application when selecting the inverter type.

Material analysis and lampshade selection:

Generally, certain materials are used as light-reflecting agents in LED lights, and these main materials are PC (polycarbonate) and PMMA (acrylic, plexiglass).

1. Polycarbonate (PC):
   • Advantages:
     • Higher light transmission rate.
     • Heat and heat resistant.
   • flaws:
     • Ease of exposure to corrosion and corrosion.
     • Possibility of yellowing when exposed to ultraviolet rays.
2. Acrylic (PMMA):
   • Advantages:
     • Easy softening at low temperatures.
   • flaws:
     • Faster softening at higher temperatures (70℃).
     • Less heat resistance compared to PC (120℃).

Based on this analysis, it appears that polycarbonate (PC) has a high light transmission rate and good heat resistance, while acrylic (PMMA) has the advantage of easy softening and low cost. Therefore, when importing LED lamps, importers must consider a balance between material quality and cost, so that a cost-effective product can be obtained rather than only focusing on low prices.
