Abstract

An LED bulb illuminates or projects images to both nearby and faraway areas. In addition, the LED bulb includes such features as three-dimensional adjustability, focus adjustment, and an extendable feature that enables components to be moved away from heat generated by the LED, and from blocking means that would interfere with operation of the components.

Claims

1. An LED bulb, comprising:

at least a first LED and a second LED;

projection means for projecting light beams from the first LED to a remote area, the projection means including optical elements and a lens for projecting the light beams from the first LED to the remote area, and at least one of a tube, digital data display, and LCD display, wherein light beams from said second LED is emitted or projected to a nearby area;

extendable and extractable means for housing components that are sensitive to heat from the LEDs or whose operation is vulnerable to interference from light or signal blocking elements, said extendable and extractable means being movable to move the components away from the heat or blocking elements;

position, orientation, or angle adjustment means for adjusting a position, orientation, or angle of said light beams projected to the remote area from the first LED; and

a base insertable into a lamp holder for connected the LED bulb to a power source.

2. An LED bulb as claimed in claim 1, further comprising elastic contact means that enable the LED bulb to be rotated upon insertion into the lamp holder to adjust a direction of the light beam in three dimensions.

3. An LED bulb as claimed in claim 1, further comprising optics means for varying a light performance of a light beam emitted by the LED bulb.

4. An LED bulb as claimed in claim 3, wherein the optics means is a focus adjustment means for adjusting a focus of the light beams from the first LED to vary a brightness, size, and performance of the light beams at desired locations or areas.

5. An LED bulb as claimed in claim 1, wherein the base is a screw type, pin type, pole type, multiple pole type, twist type, or bayonet type light bulb base.

6. An LED bulb as claimed in claim 1, wherein the LED bulb emits more than one light beam to locations, areas, and positions that are remote from the LED Bulb.

7. An LED bulb as claimed in claim 1, wherein the tube of the projection means prevents light leakage from the projection means and ensures that LED light beams passing through the optics means, optics lens, and a display unit, image forming means, LCD display, Lcos image, and/or digital display of the projection means are emitted out of the LED Bulb to desired locations, positions, and areas.

8. An LED bulb as claimed in claim 1, further comprising any of a sensor means, switch means, motion sensor means, remote control means, blue-tooth means, photo sensor means incorporated with circuit means for causing the first and second LEDs to emit light so as to provide predetermined light functions, performance, and effects.

9. An LED bulb as claimed in claim 1, wherein the extension or retractable means of the LED bulb is arranged in the LED bulb in an up, down, or horizontal arrangement.

10. An LED bulb as claimed in claim 1, wherein the LED bulb not only offers illumination for nearby areas and remote areas, but also incorporates additional functions including one of a motion sensor, remote control, and blue-tooth function.

11. An LED bulb, comprising:

at least one LED;

extendable and extractable means for housing components that are sensitive to heat from the LEDs or whose operation is vulnerable to interference from light or signal blocking elements, said extendable and extractable means being movable to move the components away from the heat or blocking elements so that they do not interfere with operation of the components; and

a base insertable into a lamp holder for connected the LED bulb to a power source.

12. An LED bulb, comprising:

at least a first LED and a second LED;

projection means for projecting light beams from the first LED to a remote area, the projection means including optical elements and a lens for projecting the light beams from the first LED to the remote area, and at least one of a tube, digital data display, and LCD display, wherein light beams from said second LED is emitted or projected to a nearby area; and

a base insertable into a lamp holder for connected the LED bulb to a power source.
