The illumination means has an LED chip and an LED support block for supporting the LED chip.

The point light source may be an LED or a light bulb.

The light (24) in the preferred embodiment is a LED or an array of LEDs.

Each channel includes an LED that is powered by a constant current source.

In the predetermined position, the projecting section (10) presses the back side of the LED (5) to engage the optical unit (4) and the LED (5), thereby aligning the axes of the two.

The patent provides an efficient high-power system-in-package LED lamp.

The invention relates to a power LED diode light source provided with a cooling system using a coolant.

Does the acoustic signal sound the same every time?

The on period of the LED is lengthened so that the product of the LED's intensity and the on period is approximately equal to the product of the desired intensity and duration of the flash.

The rendering indicating lamp can be an LED, a lamp, or a cold-cathode tube.

At least a part of the objective lens group is installed on the LED support block.

A diverging lens for a street lamp with high power LED single polycrystalline chip module is disclosed.

Even if any one of LED is disconnected or has failed, a current path is formed via the varistor for the LED connected in series to that LED so that other LED are not turned OFF.

Alarms of movement and temperature are signaled by LED diode blinking
