) added a new feature to its recently invented light emitting
diode (LED) bulbs. Its latest LED 65-watt PAR30 bulbs and the
75-watt BR30 bulbs will now have a regulator to adjust in-bulb
color temperature. Rambus introduced the LED bulbs in May.

With this feature, end users can adjust the color temperature in
LED bulbs and modulate it from 5000K (i.e. cool colors) to 3000K
(i.e. warm colors). Color temperature is a standard method of
describing colors for use in a range of situations (day to night)
and with different equipments. Color temperatures are normally
expressed in units called kelvins (K).
Rambus' innovative technology requires no additional equipments
(LEDs or multi-channel drivers) to operate the color temperature.
Instead a simple dialer fastened onto the bulbs will maintain the
desired level of color temperature, cost efficiently.
Earlier this year, Rambus, better known for its technological
inventions, introduced a technology-turned product, its first
ever LED bulbs (60-watt A19 bulbs). The bulbs, which leverage its
MicroLens optical technology, help generate consistent lighting
and control spherical distribution of light. The company asserts
that the bulbs are economical (due to lower production cost),
energy efficient and long lasting.
The bulbs have improved features such as micro-electronics,
dimmer capability, better lumen output (a measure of the total
amount of visible light emitted by a source) and advanced thermal
Rambus' LED portfolio is ready to hit the market shortly, with
the first shipment expected during the third quarter of fiscal
LED is a semiconductor light source used as indicator lamps in
many technological devices and are increasingly being used for
general lighting products. LEDs are energy efficient, long
lasting, space saving but relatively more expensive than
incandescent light sources.
With the rising popularity of energy-efficient lighting, the
in-vogue LED products are finding a place in the latest
architectural, retail, commercial and residential lighting
fixtures. We find Rambus in a favorable position to capitalize on
