About Hi-Semicon & Secondary Optical Lens

 LED optical design and secondary optical design principles

High-power LED lighting components are generally conducted the secondary optical design before
the finished product. When LED IC chip packages are assembled as the LED component, they
need to be conducted an optical design in order to solve the LED of the light angle, flux, luminous
intensity, color temperature range and distribution, which is called an optical design. Secondary
optical design is for high-power LED, the light goes through a lens and then another optical lens to
change its optical properties.

Secondary optical design is based on the optical design. Only if an optical package is designed
perfectly so that it can ensure each LED component stars out of consistent quality of the light
extraction efficacy of secondary optics and light-based optimization. In short, an optical design is
designed to remove as much as possible the light emitted LED chip, and secondary optical design
is aim to make the lighting system, the light emitted can be effectively used in the lighting.

 LED secondary optics with optical technology

LED of the secondary optical system including lenses and reflectors. From the LED OBM and OEM
assembly to applications, optical systems can be seen everywhere. As for choosing the lens or reflector
depends on what the case requires. There is no the best solution, only better ones, or good enough.

Optical design is mainly reflected in the merits of efficacy and rationality. In addition to the outdoor lighting
brightness of a certain space, but also need a range of lighting, such as street lamps illuminate the road is
the main function, and with the surrounding environment with good luminous intensity ratio (Luminance),
in order to people eye to clear roads and the surrounding environment; traffic signs and outdoor display
shall have an effective angle of view; wall washer requires a side wall of the illuminated object. If the design
has most of the optical light source not exposure to be exposure to the range, it formed a light waste, so
a reasonable distribution through professional optical technology, not only can reduce waste, while saving
LED quantity, then reduce heat, the number and the heat LED directly Reaction that is cost reduction.

 Why choose Hi-Semicon

Nowadays, LED is the newest industry in lighting field. Every industry is mustering the strength to actively
develop LED-related lighting. Surely, a prerequisite for LED lighting LED itself must be the luminance, color
temperature, and drivers supply and cooling Technical design is well controlled. In addition to the final
success or failure of key stake is the shape and the light emitted LED light efficacy. How to make the LED
lamps have the best of luminance, secondary optical lens is the key point.

Hi-Semicon’s commitment to develop innovative products together with our capability of creating custom optics
are the best response to market and application needs. We are proud to introduce the most revolutionary
optic solutions specified for any applications in the Wide Area Lighting, such as the colorful stage lighting
effects mixed light, commercial lighting of the precise light pattern, evenly luminous efficacy of home lighting,
street lighting, and a rectangular light effect.
