Abstract

LED lamps include a hollow light-transparent ball and one or more LED of the same or different colors fixed behind the ball, which has an inner semi-transparent layer and an outer transparent layer. The semi-transparent layer has a larger deflecting percentage than the outer transparent layer so that light emitted by the LED may deflect and collide with each other many times in the semi-transparent layer of the ball to produce soft and evenly mixed colored light when seen through the ball.

Claims

1. LED lamps comprising a hollow light-penetrating ball and one or more LED of the same or different colors fixed behind said ball, said ball having an inner semi-transparent layer and an outer transparent layer, said semi-transparent layer having a larger deflecting percentage than said outer transparent layer, light emitted by said one or more LED and deflected and colliding with each other inside said semi-transparent layer many times so that light seen through said ball may look comparatively soft and evenly mixed.

2. The LED lamps as claimed in claim 1, wherein said ball is a hollow spherical one.

3. The LED lamps as claimed in claim 1, wherein said ball is a hollow oval one.

4. The LED lamps as claimed in claim 1, wherein said ball is formed by means of injecting shooting process, containing a decorative matter.

5. The LED lamps as claimed in claim 1, wherein said semi-transparent layer inside said transparent layer of said ball is plated with a semi-transparent material.

6. The LED lamps as claimed in claim 1, wherein said semi-transparent layer is a sand ground surface on the inner side of said outer transparent layer.

7. The LED lamps as claimed in claim 1, wherein said semi-transparent layer is an eroded surface made on an inner side of said outer-transparent layer.

8. The LED lamps as claimed in claim 1, wherein said semi-transparent layer has a transparent section formed in a front side to increase projecting luminance.

9. The LED lamps as claimed in claim 1, wherein said ball and said LED are assembled together as integral, with said ball fixed on a transparent side of said LED and one or more dice fixed on the other side, said dice having two conductive pins extending out from two sides thereof.

10. The LED lamps as claimed in claim 1, wherein said LED preferably have some colored green, red or blue so as to produce any color expected after mixing with each other.

11. The LED lamps as claimed in claim 1, wherein said LED is controlled by a circuit consisting of a control electric circuit and a power circuit letting one or some LED to lit up or lash.

12. The LED lamps as claimed in claim 11, wherein said LED preferably have some colored green, red and blue so as to produce any color expected after mixing with each other.

13. The LED lamps as claimed in claim 11, wherein a programmed control electric circuit is provided to preset to turn on or off or flash said LED in various ways to select.

14. The LED lamps as claimed in claim 11, wherein a remote controlled receiver circuit is connected to said control electric circuit and a remote controlled transmitter to remote control lighting or flashing of said LED.

15. The LED lamps as claimed in claim 1, wherein said ball and said LED assembled integral, a conductive screw cylinder fixed at one end of said LED, a conductor fixed insulated on a center of a bottom of said cylinder, a circuit consisting of a control electric circuit and a power circuit contained in said screw cylinder, two terminals of the power respectively connected to said conductive screw cylinder and said conductor.

16. The LED lamps as claimed in claim 15, wherein a conductive screw socket is screwed with said conductive screw cylinder, a conductor fixed insulated on a bottom of said conductive screw socket to contact with said conductor of said screw cylinder, said conductive screw socket and said conductor connected to power to turn on and off said LED.

17. The LED lamps as claimed in claim 1, wherein a display unit of an LED screen is composed of said ball and plural said LED located in a concentrated condition, light emitted by plural said LED looking like only one point soft and evenly mixed when seen through said ball.

18. The LED lamps claimed in claim 1, wherein said LED lamp is used as a night lamp.

19. The LED lamps claimed in claim 1, wherein said LED lamp is used in a display lamp;

said ball placed on a socket of a base, said socket having a hole for said ball to sit therein stably, an extension base extending from a vertical side of said base, a circuit consisting of a control electric circuit and a power circuit for turning on and off or flashing said LED lamps, said extension base having a hole in an inner wall for an LED controlled by the circuit to protrude out said hole located behind said ball, an object to be displayed put in front of said ball to shine on said object with soft and evenly mixed colored light.

20. The LED lamps as claimed in claim 19, wherein said ball is a hollow spherical one.

21. The LED lamps as claimed in claim 19, wherein said ball is a hollow oval one.

22. The LED lamps as claimed in claim 19, wherein said semi-transparent layer of said ball is plated on an inner side of said outer transparent layer with a semi-transparent material.

23. The LED lamps as claimed in claim 19 said semi-transparent layer of said ball is a sand ground surface on an inner side of said outer transparent layer.

24. The LED lamps as claimed in claim 19, wherein said semi-transparent layer of said ball is a corroded surface on an inner side of said transparent layer.

25. The LED lamps as claimed in claim 19, wherein said semi-transparent layer of the ball has a transparent section formed in a front side.

26. The LED lamps as claimed in claim 19, wherein said LED preferably have some colored green, red and blue so as to produce any colors after mixing with each other.
