What factors should be considered when choosing a LED lighting Lens and reflector?
1. LED Lighting lens choices
The LED lens is an optical system that is closely connected to LED to enhance light use efficiency and luminous efficiency, and different lenses can be used to change the light field distribution of LED according to different effects. There are many types of lenses on the market, and how to choose a lens is very important.
SILICONE LENS
Silicone has high-temperature resistance and is often used to directly package LED light-emitting devices.
Silicone lenses are small
PMMA LENS
Optical grade PMMA (polymethyl methacrylate, commonly known as acrylic)
Advantages: high production efficiency
High light transmittance
Disadvantages: The temperature cannot exceed 80° (heat distortion temperature 92 degrees).
PC LENS
Optical grade material Polycarbonate (referred to as PC) polycarbonate.
Advantages: high production efficiency.
Slightly lower transmittance.
Disadvantages: The temperature cannot exceed 110° (heat distortion temperature 135°).
There are so many types of lens materials. The lens characteristics of each material are different, and you can choose according to your own needs. And Darkoo Optics LED Lighting manufacture various optical lenses and sizes and angles for you to choose from. Led lighting manufacturers in China are usually developing their optical components by PC or PMMA which could provide decent performance and cost savings.
2. LED Lighting reflector choices
A reflector is a reflector that uses a point light bulb as a light source and requires long-distance spotlighting. It is usually cup-shaped, commonly known as a reflector.
Reflectors are divided into plastic reflectors, metal reflectors, and glass reflectors according to their materials.
Plastic reflectors have poor optics and low cost. The disadvantage is that they have poor temperature resistance and are often used in lamps that require low-temperature lighting.
Metal reflectors have the advantages of moderate cost and temperature resistance, and are often used in flashlights and portable lamps.
The glass reflector has high optical precision, no deformation memory, and temperature resistance. The disadvantages are high cost, fragility, and heavyweight. Darkoo optical reflectors have a complete range of sizes and angles to meet your various needs.
