LED Lamp News

Why do we need to sound control LED lamp?Because there are times that as lazy as it makes us sound, we just don’t want to go across the room to turn on or off a light. It’s moments like that in which people start thinking up strange inventions to solve the issue. Which is probably how this voice controlled lamp came into existance. Now instead of walking to shut off the small LED lamp, you can shut it off from up to 10 meters away.That is sound control LED lamp,it can let you don’t get up while you turn off the LED lamp.

Ideal for outdoor lighting, parks, parking areas and footpaths this revolutionary LED lamp simply replaces existing bulbs. The ten year life of the LED lamp allows users to replace sodium lamp bulbs as they burn out and forget about them for a decade.

LEDs are solid-state semiconductor devices that convert electrical energy directly into light. Thermal sources of light such as flames and incandescent filaments emit light when heated, either by chemical reaction (flames) or electrical heating (filament lamps). LED “cold” generation of light leads to high efficacy because most of the energy radiates within the visible spectrum.

Other common high efficiency light sources, such as fluorescent lamps and electro luminescent devices, also produce light without much thermal radiation outside the visible spectrum. Because LEDs are solid-state devices, they can be extremely small and durable; they also provide longer lamp life than other sources.

Light is generated inside the chip, a solid crystal material, when current flows across the junctions of different material compositions.

An LED consists of two elements of processed material called P-type semiconductors and N-type semiconductors. These two elements are placed in direct contact, forming a region called the P-N junction. The composition of the different materials determines the wavelength and therefore the colour of light generated LED resembles most other diode types, but there are important differences. The LED has a transparent package, allowing visible or IR energy to pass through. Also, the LED has a large PN-junction area whose shape is tailored to the application. The device shown in Figure 1 is an AlGaInP LED because the semiconductor layers are aluminum (Al), gallium (Ga), indium (In), and phosphate (P).

Main LED materials

The main semiconductor materials used to manufacture LEDs are:

*Indium gallium nitride (InGaN): blue, green and ultraviolet high-brightness LEDs

*Aluminum gallium indium phosphide (AlGaInP): yellow, orange and red high-brightness LEDs

*Aluminum gallium arsenide (AlGaAs): red and infrared LEDs

*Gallium phosphide (GaP): yellow and green LEDs

If you’re a real tight-wad, here’s an LED lamp that will make you smile. It’s an LED lamp that is powered by your phone line. If you’re scratching your head in confusion, you must not know that phone lines carry a low level of electricity. That’s why you’re analog phones work even when the power goes out. This 8 LED lamp takes advantage of that fact by including an RJ11 plug that you can connect to any standard phone jack.
