FIELD OF THE INVENTION
 The present invention pertains to a tube. More particularly, the present invention relates to a method and apparatus for skylight tube.
BACKGROUND OF THE INVENTION
 The environmental movement has placed more emphasis on natural lighting with its many documented benefits. The most natural lighting is that provided by nature itself. However, it is often not possible to directly use nature's lighting to light an area. For example, an interior of a building may not be able to directly use nature's lighting from, for example, a window. This presents a problem.
BRIEF DESCRIPTION OF THE DRAWINGS
 The invention is illustrated by way of example and not limitation in the figures of the accompanying drawings in which:
 FIG. 1 illustrates a network environment in which the method and apparatus of the invention may be controlled;
 FIG. 2 is a block diagram of a computer system which some embodiments of the invention may employ parts of; and
 FIGS. 3-29 illustrate various embodiments of the present invention.
 A method and apparatus for a skylight tube is disclosed. In one approach an apparatus using reflective tube with insertable diffusers provides thermal insulation and light transmission. These and other embodiments of the present invention are described in the writings and drawings herewith.
 In one embodiment of the invention, a light source, such as, for example, a light bulb, light emitting diode, compact fluorescent, etc. is strategically placed within a flexible reflective tube to provide artificial lighting when natural lighting is not sufficient for a user.
 In one embodiment the invention may be tailored to a particular client zone. For example, in one embodiment, the exterior ambient temperature may lead to excessive heat loss or heat gain for an interior environment and so in one embodiment, diffuser lenses may be inserted/removed to adjust the thermal resistance between the exterior and interior environment.
 In one embodiment of the invention a dome made of a material transparent to visible light ("light") and possibly other radiation, for example, but not limited to, infrared radiation (e.g. clear polycarbonate, plastic, glass, etc.) is attached to a flashing made for example of, but not limited to, metal.
 In one embodiment of the invention the flashing may be formed into a square type box.
 In one embodiment of the invention a flange secured below the dome within the flashing's square box may join the top end of flexible ("flex") tubing ("tube") to the flashing.
 In one embodiment of the invention the flex tube, reflects and directs sunlight to diffuser(s) below.
 In one embodiment of the invention a light kit, with a light bulb socket with mounting brackets for lighting (e.g. night time) may be placed inside the flex tube.
 In one embodiment of the invention one or more diffuser lenses (for example, 3-5 lenses) may be placed inside the flex tube depending upon a user requirement, for example, but not limited to, different climate zones.
 In one embodiment of the invention a diffuser casing, for example, but not limited to a clam shell design, may house for example, up to 5 lenses.
 In one embodiment of the invention a diffuser housing, holds the diffuser assembly and connects the lower end of the flex tube to the ceiling, of for example, a room. The housing is secured to the ceiling.
 In one embodiment of the invention a decorative ring which may be paintable or of a variety of colors is attached to the diffuser housing.
 FIG. 3 illustrates, generally at 300, one embodiment of the invention showing a clear dome 302 for admitting light, a flashing 304 which is secured to the dome 302 and permits mounting, for example, on a roof, a reflective flexible tubing 306, which is attached to the flashing 304 and when fully assembled to the diffuser housing 310. At 308 is a light assembly that may be mounted on top of diffuser housing 310 and emit light within the reflective flexible tubing 306. At 312 are one or more diffusers which are housed in diffuser casing 314. Diffuser casing 314 is inserted into diffuser housing 310. At 316 is a ring which attaches to diffuser housing 310.
 FIGS. 4-29 illustrate embodiments of the present invention.
 In one embodiment of the invention, the dome/flashing assembly is:
 1) The dome: square configuration, low profile, transitioned to round flex tube.
 2) The flange: make transition from square dome to round tube. Also serves as flex tube's top anchor to the flashing and the storage compartment of flex tube when it is collapsed.
 3) Flashing, deep draw to form dome's square box with no welds or fasteners to create a leak-proof assembly.
 In one embodiment of the invention, the diffuser assembly is:
 1) Diffuser is capable of holding up to 5 lenses, providing flexibility in customization for different climate zones for best thermal insulation, solar heat gain and light transmission.
 2) Diffuser casing's clam shell design with easy-to-use latches.
 3) 0.62'' of spacing between lenses creates best thermal insulation. This is implemented on the placing of lens #1, 2 and 3. (see Bill of Materials in Figure).
 In one embodiment of the invention, the spacing between diffuser lenses is between 0.1'' to 1.5''.
 Thus a method and apparatus for skylight tube have been described.
 FIG. 1 illustrates a network environment 100 from which the techniques described may be controlled, for example the light kit. The network environment 100 has a network 102 that connects S servers 104-1 through 104-S, and C clients 108-1 through 108-C. More details are described below.
 FIG. 2 is a block diagram of a computer system 200 which some embodiments of the invention may employ parts of (e.g. controlling light kit) and which may be representative of use in any of the clients and/or servers shown in FIG. 1, as well as, devices, clients, and servers in other Figures. More details are described below.
 Referring back to FIG. 1, FIG. 1 illustrates a network environment 100 in which the techniques described may be controlled. The network environment 100 has a network 102 that connects S servers 104-1 through 104-S, and C clients 108-1 through 108-C. As shown, several computer systems in the form of S servers 104-1 through 104-S and C clients 108-1 through 108-C are connected to each other via a network 102, which may be, for example, a corporate based network. Note that alternatively the network 102 might be or include one or more of: the Internet, a Local Area Network (LAN), Wide Area Network (WAN), satellite link, fiber network, cable network, or a combination of these and/or others. The servers may represent, for example, disk storage systems alone or storage and computing resources. Likewise, the clients may have computing, storage, and viewing capabilities. The method and apparatus described herein may be controlled by essentially any type of communicating means or device whether local or remote, such as a LAN, a WAN, a system bus, etc. For example, a network connection which communicates via for example wireless may control an embodiment of the invention having a wireless communications device. Thus, the invention may find application at both the S servers 104-1 through 104-S, and C clients 108-1 through 108-C.
 Referring back to FIG. 2, FIG. 2 illustrates a computer system 200 in block diagram form, which may be representative of any of the clients and/or servers shown in FIG. 1. The block diagram is a high level conceptual representation and may be implemented in a variety of ways and by various architectures. Bus system 202 interconnects a Central Processing Unit (CPU) 204, Read Only Memory (ROM) 206, Random Access Memory (RAM) 208, storage 210, display 220, audio, 222, keyboard 224, pointer 226, miscellaneous input/output (I/O) devices 228, and communications 230. The bus system 202 may be for example, one or more of such buses as a system bus, Peripheral Component Interconnect (PCI), Advanced Graphics Port (AGP), Small Computer System Interface (SCSI), Institute of Electrical and Electronics Engineers (IEEE) standard number 1394 (FireWire), Universal Serial Bus (USB), etc. The CPU 204 may be a single, multiple, or even a distributed computing resource. Storage 210, may be Compact Disc (CD), Digital Versatile Disk (DVD), hard disks (HD), optical disks, tape, flash, memory sticks, video recorders, etc. Display 220 might be, for example, an embodiment of the present invention. Note that depending upon the actual implementation of a computer system, the computer system may include some, all, more, or a rearrangement of components in the block diagram. For example, a thin client might consist of a wireless hand held device that lacks, for example, a traditional keyboard. Thus, many variations on the system of FIG. 2 are possible.
 For purposes of discussing and understanding the invention, it is to be understood that various terms are used by those knowledgeable in the art to describe techniques and approaches. Furthermore, in the description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be evident, however, to one of ordinary skill in the art that the present invention may be practiced without these specific details. In some instances, well-known structures and devices are shown in block diagram form, rather than in detail, in order to avoid obscuring the present invention. These embodiments are described in sufficient detail to enable those of ordinary skill in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that logical, mechanical, electrical, and other changes may be made without departing from the scope of the present invention.
 Some portions of the description may be presented in terms of algorithms and symbolic representations of operations on, for example, data bits within a computer memory. These algorithmic descriptions and representations are the means used by those of ordinary skill in the data processing arts to most effectively convey the substance of their work to others of ordinary skill in the art. An algorithm is here, and generally, conceived to be a self-consistent sequence of acts leading to a desired result. The acts are those requiring physical manipulations of physical quantities. Usually, though not necessarily, these quantities take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, and otherwise manipulated. It has proven convenient at times, principally for reasons of common usage, to refer to these signals as bits, values, elements, symbols, characters, terms, numbers, or the like.
 It should be borne in mind, however, that all of these and similar terms are to be associated with the appropriate physical quantities and are merely convenient labels applied to these quantities. Unless specifically stated otherwise as apparent from the discussion, it is appreciated that throughout the description, discussions utilizing terms such as "processing" or "computing" or "calculating" or "determining" or "displaying" or the like, can refer to the action and processes of a computer system, or similar electronic computing device, that manipulates and transforms data represented as physical (electronic) quantities within the computer system's registers and memories into other data similarly represented as physical quantities within the computer system memories or registers or other such information storage, transmission, or display devices.
 An apparatus for performing the operations herein can implement the present invention. This apparatus may be specially constructed for the required purposes, or it may comprise a general-purpose computer, selectively activated or reconfigured by a computer program stored in the computer. Such a computer program may be stored in a computer readable storage medium, such as, but not limited to, any type of disk including floppy disks, hard disks, optical disks, compact disk-read only memories (CD-ROMs), and magnetic-optical disks, read-only memories (ROMs), random access memories (RAMs), electrically programmable read-only memories (EPROM)s, electrically erasable programmable read-only memories (EEPROMs), FLASH memories, magnetic or optical cards, etc., or any type of media suitable for storing electronic instructions either local to the computer or remote to the computer.
 The algorithms and displays presented herein are not inherently related to any particular computer or other apparatus. Various general-purpose systems may be used with programs in accordance with the teachings herein, or it may prove convenient to construct more specialized apparatus to perform the required method. For example, any of the methods according to the present invention can be implemented in hard-wired circuitry, by programming a general-purpose processor, or by any combination of hardware and software. One of ordinary skill in the art will immediately appreciate that the invention can be practiced with computer system configurations other than those described, including hand-held devices, multiprocessor systems, microprocessor-based or programmable consumer electronics, digital signal processing (DSP) devices, set top boxes, network PCs, minicomputers, mainframe computers, and the like. The invention can also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network.
 The methods of the invention may be implemented using computer software. If written in a programming language conforming to a recognized standard, sequences of instructions designed to implement the methods can be compiled for execution on a variety of hardware platforms and for interface to a variety of operating systems. In addition, the present invention is not described with reference to any particular programming language. It will be appreciated that a variety of programming languages may be used to implement the teachings of the invention as described herein. Furthermore, it is common in the art to speak of software, in one form or another (e.g., program, procedure, application, driver, . . . ), as taking an action or causing a result. Such expressions are merely a shorthand way of saying that execution of the software by a computer causes the processor of the computer to perform an action or produce a result.
 It is to be understood that various terms and techniques are used by those knowledgeable in the art to describe communications, protocols, applications, implementations, mechanisms, etc. One such technique is the description of an implementation of a technique in terms of an algorithm or mathematical expression. That is, while the technique may be, for example, implemented as executing code on a computer, the expression of that technique may be more aptly and succinctly conveyed and communicated as a formula, algorithm, or mathematical expression. Thus, one of ordinary skill in the art would recognize a block denoting A+B=C as an additive function whose implementation in hardware and/or software would take two inputs (A and B) and produce a summation output (C). Thus, the use of formula, algorithm, or mathematical expression as descriptions is to be understood as having a physical embodiment in at least hardware and/or software (such as a computer system in which the techniques of the present invention may be practiced as well as implemented as an embodiment).
 A machine-readable medium is understood to include any mechanism for storing or transmitting information in a form readable by a machine (e.g., a computer). For example, a machine-readable medium includes read only memory (ROM); random access memory (RAM); magnetic disk storage media; optical storage media; flash memory devices; devices having movement in matter (e.g. electrons, atoms, etc.) caused by physical excitation or reception of electrical, optical, acoustical or other form of propagated signals (e.g., carrier waves, infrared signals, digital signals, etc.) which upon reception causes said movement in matter.
 As used in this description, "one embodiment" or "an embodiment" or similar phrases means that the feature(s) being described are included in at least one embodiment of the invention. References to "one embodiment" in this description do not necessarily refer to the same embodiment; however, neither are such embodiments mutually exclusive. Nor does "one embodiment" imply that there is but a single embodiment of the invention. For example, a feature, structure, act, etc. described in "one embodiment" may also be included in other embodiments. Thus, the invention may include a variety of combinations and/or integrations of the embodiments described herein.
 As used in this description, "substantially" or "substantially equal" or similar phrases are used to indicate that the items are very close or similar. Since two physical entities can never be exactly equal, a phrase such as ""substantially equal" is used to indicate that they are for all practical purposes equal.
 It is to be understood that in any one or more embodiments of the invention where alternative approaches or techniques are discussed that any and all such combinations as may be possible are hereby disclosed. For example, if there are five techniques discussed that are all possible, then denoting each technique as follows: A, B, C, D, E, each technique may be either present or not present with every other technique, thus yielding 2 5 or 32 combinations, in binary order ranging from not A and not B and not C and not D and not E to A and B and C and D and E. Applicant(s) hereby claims all such possible combinations. Applicant(s) hereby submit that the foregoing combinations comply with applicable EP (European Patent) standards. No preference is given any combination.
 Thus a method and apparatus for skylight tube have been described.
