LED track spotlight project a
narrow, intense beam of white
light directly onto a place or person.
Spotlights are primarily suited
for environments that require sharp,
uniform beams such as in the
retail and hospitality industry. The
new adjustable beam angle spotlight
provides a wide flood 60° beam
angle which can be adjusted to a
24° spot without the use of any
additional lenses or reflectors.
This fully adjustable spotlight
provides all the benefits of LED
technology, no UV / IR radiation,
50.000 hours life at 70% luminous
flux, maintenance free applications
and a considerable reduction in
energy consumption over traditional
light sources such as halogen.
This LED track spotlight is available
in 2700K, 3000K, 4000K and 5000K,
CCT with a high color rendering
index, typical CRI 90~92 with
dimmable function, essential
requirements for museums,
galleries and high-end retail
applications. The adjustable beam
angle spotlight is a true revolution
in accent and display spot lighting.

4. Notes:
 Be sure the power is off before you install the lamp.
 Do not use the lamp for outdoor lighting, it is indoor use only and prevent to touch the
chemicals.
 Do not look into the lamp directly and prevent shine of your eyes.
 Do not touch the fixture shades or lamp shield while the lamp is on, the lamp surface is hot
Installation Procedure
Step 1: Make sure that power supply is off. The track light should be “off”. Step 3: After fixing the track light on track system, turn switch
on. Choose ‘1’, ‘2’ or ‘3’ and make lamp ‘on’ and ‘off’.
Step 2: Attach the track light in the track system directly. Then turn the
button to fix the track light.

5. Tunable lenses offer compact solution to combine floodlights and
spotlights in one product
When designing an LED spotlight, components are available that enable many different beam angles.
However, because each component usually provides a fixed beam angle, the customer has to decide in the
design phase what beam angle (or angles) to use for an installation.
Sometimes it’s possible to exchange optics to produce different beam angles. However, this is time
consuming and cumbersome, especially as
lamps are often hard to access after the
installation is completed.
Other solutions are available that enable a
variation in the beam angle without exchanging
components, but they are inefficient and can be
complex. In some cases it’s possible to shift the lens away from the LED to focus the beam (up to a certain
point). However, rings and shadows typically appear in the spot, and a lot of light is lost as the distance from
the LED increases.
On the other hand, large show-lights or even some museum lights are equipped with a zoom lens for spot-
size adjustment. As well as requiring lots of space and being inefficient, such zoom lenses are expensive in
development and manufacturing, making them unsuitable for mass lighting applications.
Tunable lenses
The tunable-lens technology allows the beam angle to be set on site and to be adjusted whenever necessary.
There is even the possibility of motorizing the tuning process for remote-controlled adjustments.
As well as reducing complexity costs by
having just one product that can produce a
range of outputs, from flood to spot, the
tunable lens also offers new opportunities
to change the beam angle for different
settings, for example in a museum with
changing exhibitions.
The principle of the tunable-lens
technology is outlined in Fig. 1. A ring, or
so-called lens shaper, is pressed into a
polycarbonate container filled with an
optical liquid and sealed with a thin
FIG. 2.

6. polymer membrane. This causes a spherical lens to form. The focal length of the lens changes in proportion
to the liquid pressure. The clear aperture remains constant throughout the whole tuning range.
While being very efficient and compact, this technology allows a flexible adjustment of the beam angle
when implemented in a spotlight. Turning a ring controls the movement of the lens shaper into the liquid-
filled container and therefore the shape of the lens. A cogwheel in the housing offers the possibility of
motorizing this process, enabling remote control of the beam angle.
Optical design
The optical design of a spotlight with a tunable lens is outlined in Fig. 2. The LED and the secondary optics
define the maximum beam angle. It’s important to use secondary optics with an even light distribution for a
good tuning result. The tunable lens is then used to focus the beam from the wide flood angle to a narrow
spot beam.
Although a very new technology, tunable lenses have been extensively tested in various environments.
Based on these results, the expected lifetime of the tunable lens is over 10 years within the operating
temperature range of -20°C to 85°C. The lenses are built in a dust-free environment (clean room) and have a
protective housing to keep them clean. However, the current products do not have waterproof housings, and
are only suitable for indoor use.
