Title: Stick-On Lamp Board and Uses Thereof

Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to the fields of lighting systems and light-emitting diodes (LED). More particularly, the present invention relates to LED based lamps utilizing a combination of LED types. 
     Description of the Related Art 
     Light emitting diodes (LEDs) work on the principle of passing a current through semiconductors. Through the combination of electrons and holes, excess energy is released in the form of light to achieve the effect of light emission. LEDs have many advantages in the field of lighting due to their longer life expectancy, low power consumption, fast response time, small size and light weight. In addition to their easily controllable dimming characteristics, they are available in a variety of colors. 
     Moreover, the components required to manufacture LEDs do not contain environmental pollutants like mercury and lead. Currently, LED based lighting systems use either surface mounted devices (SMD) LEDs, which have flooding and light performance features, or Direct In-line Package (DIP) LEDs (also known as straw hat lamp LEDs), which demonstrate high brightness and condensing performance. 
     There is, therefore, a need in the art for a lighting device that can combine the properties of both Surface Mounted Devices LEDs and Direct In-line Package LEDs. 
     The present invention fulfills this long-standing need and desire in the art. 
     SUMMARY OF THE INVENTION 
     The present invention is directed to a light emitting diode (LED) array. The LED array has a printed circuit board to which a plurality of LEDs comprising a combination of lamp bead types are fixedly mounted on a top side of the printed circuit board and are operably connected therewith. A power supply is operably connected to the circuit board. The present invention is directed to a related LED array further comprising means for removably securing the printed circuit board to a surface disposed on a bottom side of the circuit board. 
     The present invention also is directed to a set of LED lamp boards. The LED lamp boards comprise at least two of the LED arrays as described herein. A means for removably securing each of the at least two LED arrays to a surface is disposed on a bottom side of each. 
     The present invention is directed further to a stick-on lamp board. The stick-on lamp board has a printed circuit board comprising a top side and a bottom side. A combination of SMD lamp beads and DIPS lamp beads is fixedly mounted in a geometric pattern on the front side of the printed circuit board and operably connected therewith. A means for removably securing the printed circuit board to a surface is disposed on a bottom side thereof. 
     The present invention is directed further still to a set of LED lamp boards. The set comprises at least two of the stick-on lamp boards as described herein.

In yet another aspect the fourth stick-on lamp board has a hexagonal shape. 
     Provided herein are LED arrays, LED lamp boards, for example, stick-on lamp boards, and sets and lighting systems comprising the same. The LED arrays and LED lamp boards comprise a printed circuit board (PCB), a plurality of LEDS that are a combination of lamp bead types mounted to the printed circuit board and a power supply, either external or internal, as is known in the art, operably connected to the printed circuit board. An example of a power supply is a battery. 
     The printed circuit board is known in the art and commercially available. The circuit board may have any geometric shape. Generally, the geometric shape is a polygonal shape, a disk shape or a ring shape. Particularly, the polygonal shape may be, but is not limited to, a diamond, a square, a rectangle, a hexagon, or a triangle. The printed circuit board, the LED array and the LED lamp boards may comprise a means for removably or permanently securing, attaching, affixing, or mounting the same to a surface, for example, but not limited to, a wall, a ceiling, or other surface inside or outside a building, house or other structure. Examples of such securing means are well-known in the art and include, but are not limited to, an adhesive, VELCRO or hardware for hanging an object. 
     The combination of lamp bead types may be commercially available surface mounted devices (SMD) LEDs and Direct In-line Package (DIP) LEDs. The SMD LEDs comprise RGB-color features. The lamp beads are fixedly mounted to the circuit board by, for example, soldering, which operably connects the lamp beads to the circuit board and there by to the power supply as is well-known in the art. The lamp beads are uniformly arranged on the circuit board in rows, i.e., linear, or in any non-linear configuration. The lamp beads cover the surface of the printed circuit board such that the overall shape thereof formed on the board corresponds to the geometric shape of the printed circuit board. The lamp beads may be aesthetically arranged on the circuit board. Within the covering of lamp beads on the circuit board, geometric patterns are formed by groupings of the lamp beads in polygonal or circular geometric shapes. In non-limiting examples, the geometric patterns formed by the combination of lamp beads may be diamond patterns, triangular patterns, hexagonal patterns, in a circular pattern or in a concentric ring pattern. 
     The LED arrays and LED lamp boards provided herein may comprise a set or a lighting system. For example, the set or the lighting system may comprise at least two of the LED arrays or the LED lamp boards, for example, two or more stick-on lamp boards. The set or lighting system may comprise LED arrays or LED lamp boards with the same geometric shape and lamp bead pattern or a combination of geometric shapes and lamp bead patterns. In a non-limiting example, a lighting system may comprise at least one of a rectangular shaped or a square shaped first stick-on lamp board with a diamond pattern of lamp beads, a rectangular shaped or a square shaped second stick-on lamp board with a triangular patterns of lamp beads, a disk shaped or ring shaped third stick-on lamp board with a circular pattern of lamp beads, a hexagonal shaped fourth stick-on lamp board with a hexagonal pattern of lamp beads, or a disk shaped or ring shaped fifth stick-on lamp board with a diamond pattern of lamp beads, or combinations of the first, second, third, fourth, and fifth stick-on lamp boards. 
     The LED arrays, LED lamp boards and stick-on lamp boards have the beneficial effects of simultaneously combining the high brightness and condensing performance of the direct in-line package LED lamp beads and the flooding and light performance of the surface mounted devices LED lamp beads. Also, the RGB-color features in the SMD lamp beads enable wide practical applications of the stick-on lamp board.
