Abstract: A tubular light includes a light set having a substrate with light emitting diodes mounted on the substrate so as to electrically connect to the substrate, a tubular cover made of a translucent material, the tubular cover having a receiving space defined therein, a positioning seat formed to securely receiving the substrate in the receiving space, and a securing device securely engaged with the tubular cover and adapted to securely engage to a surface.

Abstract: A wireless optic mouse includes a casing inside which an optic module, a wireless communication unit and a built-in power source are arranged. The power source powers the optic module and the wireless communication unit. The optic module includes an infrared light emitting diode capable to emit an infrared signal of wavelength between 800-1,000 nm and a sensor for receiving the infrared signal that is reflected by a desk surface. The sensor generates a signal in response to the infrared optic signal received and applies the signal to the wireless communication unit that transmits the signal to a host computer in a wireless manner. The operation of the optic module is based on the infrared light that requires low power consumption but provides a high precision. Thus the service life of the power source is extended. The wireless communication between the mouse and the host computer realizes excellent mobility of the mouse.

Abstract: A light emitting diode has a base made of electrically conductive material and having a receiving recess defined in a top of the base and at least one step formed on a peripheral edge thereof, a lighting chip received in the receiving recess of the base, a heat dissipating element made of electrical insulation material and having at least two supports extending out of the heat dissipating element to electrically connect to the lighting chip. The heat dissipating element is mounted on top of the base and is so configured to mate with the at least one step of the base. A translucent cover is mounted on top of the heat dissipating element.

Abstract: An optical mouse has a light emitting diode (LED) and a projecting lens located on a reflection path of the LED so as to project the light of the LED to the sensor. After the sensor picks up the signal from the LED, the signal is readily sent to the computer so as to simplify the structure and reduce the manufacturing cost of the optical mouse.

Abstract: A stacked light-mixing LED includes a main body, more than one connecting parts, a first chip, and a second chip. Two lights with different wavelength in the visible light spectrum area, such as the yellow light and the blue light, or the green light and the red light, are respectively excited and emitted from the first chip and the second chip. By controlling electrical current and voltage, the two lights respectively excited from the first chip and the second chip can be symmetrically mixed into another wavelength of light in the visible light spectrum area, such white light.

Abstract: An illuminant radio communication device has a console and a cordless phone communicating with the console. The cordless phone has at least one light emitting diode controlled by the control button on the cordless phone so that the cordless phone is able to provide sufficient light when needed.
