We are frequently asked what makes a good reflector and which type of reflectors we use. As the word “reflector” suggests, the first and formost quality is the capabililty to reflect light properly, or with other words its reflectivity. The more light a reflector can direct to the desired area, the higher its quality. 
 

This leads us directly to the next question, the material of the reflector. Aluminum is one of the top materials due to its high reflectivity, light weight and stability. By anodizing or coating the aluminum reflector, even a higher level of reflectivity and reflector lifespan can be achieved.
 

 

The shape and design of the reflector also plays a crucial role and determines how well it can control and distribute light. Different shapes, such as parabolic or faceted reflectors, may be used depending on the desired light distribution pattern. Parabolic reflectors are typically used for light sources with a need of high light output, such as high bay lights and street lights. Facettted reflectors on the other hand, allow controlled and defined light distribution and can additionally contribute to the reduction of glare. Typical applications include indoor track lights and architectural lighting where high beam angle precision is needed.
 

Last but not least a proper heat resistance is crucial for LED reflectors. LEDs generate some heat during operation, and the reflector should be able to withstand this heat without deforming or losing its reflective properties. Also in this case aluminum reflectors have proven to be very suitable due to their high thermal conductivity and hence good heat dissipation. 
 

Last but not least, the lifespan of a reflector plays an important role. The reflector should be durable and able to withstand environmental conditions. UV-resistant coatings or materials can help prevent degradation over time, especially in outdoor applications.
