Optics is known as the soul of LED luminaire. Without soul, only aluminum plate, housing, and LEDs left, whole value depreciates extensively.

Now the question is: How shall we build the soul of LED luminaire?

Lens and reflector are the common optic components HTA adopts.

HTA chooses lens or reflector to realize different optical effects, and thus to suit different applications. LED lenses are usually made of PMMA, which features easy deformability and high light transmittance, while low temperature resistance with only 90 degree. The main lens HTA adopts is one of total internal reflection, TIR in short, through which front light penetrates right ahead, with side light all reflected by the conical surface; even light distribution and beautiful spot light thus come into being when the two beams overlap. TIR lens’ efficiency can reach 90% and above, mainly used in narrow beam angle luminaire (beam angle < 60 degree), like spotlight, downlight, etc..

LED reflectors are usually made of metal or plastic, which reflect light from lighting source in designed angle, to reach the goal of using light energy effectively. The light extraction efficiency of LED reflector is comparably lower, while volume bigger.
