Background In the late 1800's, "pre-electric age" liquid paraffin powered Illuminators, an example of which is shown in fig 13, as well as gas powered illuminators, began to be replaced by the incandescent electric Lamp. Fig 2 depicts a reproduction of an early incandescent electric Lamp. The conventional incandescent Lamp, commonly called the "light bulb" has been used for over one hundred years in one form or another. An example as in fig 3 of the conventional incandescent Lamp, mostly uses a tungsten filament 7, enclosed in a glass bulb 8 sealed in a base 9, which is mated to a socket 10. The socket 10 is 5 connected to an ac power or dc power source, usually via a control circuit or switch mechanism. Unfortunately, drawbacks exist with the conventional incandescent Lamp. The conventional incandescent Lamp dissipates much wasted thermal energy. Eg: more than 90% of the energy used dissipates as thermal energy. Additionally, the conventional incandescent Lamp routinely fails often due to thermal expansion and contraction of the filament element or mechanical vibration. To overcome some of the drawbacks of the conventional incandescent Lamp, fluorescent lighting was developed. Fluorescent lighting tubes as in fig 4, use an optically clear tube coated with phosphors. The tube structure(s) may be filled with gas(es), eg: Argon, Krypton, Xenon, or Neon and typically also contain mercury. As in fig 4, a pair(s) of electrodes via pins 11 is coupled between the gas and an ac power source via a "ballast". Once the gas has been excited, it discharges to emit light. The mass produced incandescent Lamps are now being phased out in many countries to help reduce energy costs due to their typically inefficient 20 lumens/watt (Im/w) efficacy. Their replacement was to be the Compact Fluorescent Lamp (CFL) 12, which first came into use in the early 1970's. It is the Inventors' opinion that the phasing out of these prior art incandescent Lamps was premature and that these CFLs have been somewhat disappointing and have struggled to achieve a true "Luminous replacement" for the Incandescent Lamp. Most of these CFL Lamps contain Mercury (later Osram brand CFL Lamps are an exception), which is harmful to assembly operators during production and is often carried out in third world countries where worker health is often less important than in the more industrialized Western countries. Additionally, when a CFL Lamp breaks, toxic mercury is spilt on the ground/floor posing severe environmental hazards in, for example, a standard home, where the long lasting toxicity is often not appreciated. The word "Efficacy" used herein relates to luminous efficacy. Luminous efficacy is a measure of how well a light source produces visible light. It is defined as the ratio of luminous flux (measured in Lumens (Im)) to electrical power input (measured in watts (w)), i.e: Lumens per watt or Im/w. In this context we will refer to the ratio of "luminous flux-output" (visible to the human eye) to "electrical-power-input" as the luminous 6 efficacy (Im/w) or just efficacy. Fig 18 shows a graph of Efficacy versus Time for Lighting Technology improvements including LED evolvements. Recently, Solid-state lighting techniques with their improved efficacies have also been used to replace the conventional incandescent Lamp. Solid-state lighting relies upon semiconductor materials to produce light emitting diodes (LEDs), especially High Brightness LEDs (HB LEDs). Fig 5 shows a small representative example of prior art HB LED Lamps with different translucent Lamp Covers 13 and heat dissipating protrusions. With the ever increasing demand for more efficient Lamps, solid state devices such as High Brightness LEDs (HB LEDs) have in recent years become readily available and are being used in Lighting Devices and Illuminators. With some of these modern HB LED Lamps comes a need for new style Lamp connectors. One such example is the Molex Series 180150 LED array holder shown in fig 7, designed for the Bridgelux model ES LED Chip-On-Board (COB) Array, which uses "finger connectors" 14 and clips to connect the electrical contacts to the LED Module's electrical contacts and "fixes" the LED COB array to the holder. This holder allows for a relatively easy attachment of the large Bridgelux ES LED COB array to the array holder. We note that the LED industry often refers to COB arrays as being "Chip-On-Board", but the Inventors have observed that the majority of the time they are predominantly LED "Die"-On-Board arrays. For the purposes of this Invention we will consider that the term COB refers to Die-On-Board unless stated otherwise. Another HB LED connector product is the Tyco Electronics' (TE) solder-less LED socket system, Type LS as in fig 8. This particular style of socket is designed to receive a Luxeon S Multi-die LED Chip and according to the manufacturer, has the ability to easily place an LED Lamp anywhere in a Lighting Device. This socket provides for a "snap together" means of assembly for an LED Chip 15, an optic element (not shown), an LED Lamp base 16, and solder-less snap-on power connection 17. Another "quick connect" system for an LED Lamp is the TALEXX engine STARK DLE TWIST as in fig 9, which facilitates a simple "twist and lock" mounting solution for an LED Lamp within an Illuminator. 7 An "Illuminator" as described herein, is defined as an electrical Lighting Device having at least: one Housing, one Lamp, one electrical power input means and one Lamp Cover. The lamp(s) of the Illuminator produces artificial light to illuminate. A "Lamp" as described herein is defined as that part of an Illuminator that creates the light emission. In the case of LED Illuminators, an example of a Lamp is shown in fig 11 which is an LED Lamp containing LED Chips 24 where the LED Chips 24 are attached to a PCB 25 which contains components of a Power Control Module (PCM) with one component highlighted 23. A PCB as described herein is usually a rigid, non-electrical-conducting substrate or board (e.g. ceramic, synthetic resin, metal compound or laminate) on to which is laid (e.g. by a process of chemical etching, laminating, or metallising) tracks, electrical connections or pathways for the mechanical support and electrical connection of mostly electronic components, e.g. LEDs, or other components. Looking more closely at Lamps and how they are attached in Illuminators, we find that Lamps are typically attached in predominately two different ways. Firstly there are those Lamps that are "removably" attached in an Illuminator and are mostly attached via a Lamp socket(s) 10 type connector (to be removably attached) and are designed to have for example, a male plug type connector 9 mate to a matching female socket type connector 10, which provides an electrical connection to the Lamp and supports it in its Illuminator. The use of Lamp sockets has allowed Lamps to be mostly safely, conveniently, and easily changed out at end of life or as needed. There are many different standards for these connector sockets, created by de facto and by various "Standards Bodies" (eg: International Electrotechnical Commission (IEC), International Organization for Standardization (ISO), American National Standards Institute (ANSI), and others. Some of the more commonly used Lamp bases in Australia are shown by their many different representative drawings in fig 6. This list is not an exhaustive list but used for example depiction only. The second way of attachment of a Lamp in an Illuminator is that a Lamp may be permanently "lifetime" attached to an Illuminator's Housing by screws and/or other mechanical or chemical bonding (eg: an appropriate adhesive) means. If the Lamp needs to be replaced, it is a simple matter to replace the complete Illuminator including the permanently attached Lamp(s). 8 Using the Illuminator of fig 10 as a further aid to describe an LED Lamp within an LED Illuminator, LED Chip(s) 21(x9) are attached to the PCB 20, forming an LED Lamp Module 20+21(x9), and an optic (reflector) 18 is fitted for controlling and modifying the light output. (Note: The Illuminator Cover is not depicted). In this example the LED Lamp Module 20+21(x9) contains nine single LED Chips 21, but in another example the HB LED Chip(s) contained within the LED Lamp Module could be single LED Chips (or multiples thereof), or they could be larger COB LED array(s) (or multiples thereof). In the example shown in fig 10, the PCB substrate board 20 allows for the electrical connection of the LED Chip(s) 21(x9) by PCB tracks to solder pads for electrical connections of the LED Lamp Module 20+21(x9). The LED Lamp Module 20+21(x9) is further attached permanently to the inner surface of the LED Lamp Housing 19 to form the LED Lamp Module segment 19+20+21(x9), whereby the LED Lamp Module segment 19+20+21(x9) may then be further attached to the Illuminator Housing 22, and allows Lighting Designers flexibility in their designs. In one of an Illuminator's minimal forms, an LED Lamp Module segment may represent a complete Illuminator by itself only requiring connection to an appropriate power supply and a Lamp Cover to add some degree of protection to the Illuminator's components. In this case, the LED Lamp Module segment's LED Lamp Housing also functions as the Illuminator's Housing. There must be in most cases, at least some degree of control from an electrical or electronic module(s) to allow for a modification to the power supply form(s), and/or current(s) and/or voltage(s) to the HB LEDs, if only to be able to adjust voltage for ageing of the HB LED(s) or to turn on/off or attenuate/dim the HB LED Lamp module(s) for a particular environment or function. The module that is used to "control" to a degree the power to the LED Lamp(s) is, for the purpose of description, called a Power Control Module (PCM). An LED Lamp(s) Module usually requires a specialised PCM to modify the power supplied to a required form, and is usually included in-circuit between the power supply and the LED Chip(s). Some LED Lamp Modules are able to be connected directly to an ac power source as they have a special onboard PCM, e.g. Tesla ac LEDs as shown in fig 12. 9 Illuminators are often described informally by their intended use, how they are installed, and the Lamp type or function. Looking more closely at Illuminator's functions as they relate to the Invention, we describe Illuminators that have the function(s) of illuminating near and/or onto an area and/or surface, namely a Thoroughfare, eg: street, roadway, walkway, pathway, private or public area. These types of Illuminators can be found in: eg: Street lighting, Roadway lighting, Expressway lighting, Tunnels, Underpass lighting, Public Park pedestrian lighting, Pathway Lighting, Security Lighting, and underground Mining operational lighting. These types of Illuminators, function by mostly illuminating steadily when required, and when operationally and permanently installed provide an illumination function predominately to aid in outdoor human movement, human endeavour, safety, security, and/or where there is required and/or regulated function(s). We refer to these types of Illuminators (excluding Beacon Lights) whose function(s) is to illuminate onto and/or near a Thoroughfare, and are permanently situationally lifetime fixed in place as "Thoroughfare Illuminators". Thoroughfare Illuminators as they relate to the Invention are categorised (cat) as follows, with their functions (fn) and groups: Thoroughfare Illuminator (Thoroughfare lighting) cat 1 - Street lighting fn 1 - Beacon lighting fn 2 - Roadway lighting group 1 - Major road lighting group 2 - Minor road lighting fn 3 -Security lighting cat 2 - Area lighting fn 1 - Public area lighting fn 2 - Private area lighting cat 3- Walkway lighting fn 1 - Pedestrian lighting A Thoroughfare Illuminator usually has a support fixture (eg: A light pole outreach arm or tethered chain), which in-turn is usually mounted to a pole that is permanently and 10 securely fixed to the earth, or to a structure that is securely fixed to the earth (eg: a building, tunnel ceiling, utility pole), and is generally a raised source of light on the edge of a Thoroughfare, and is usually illuminated when there is a required and/or regulated function(s) to add extra light in addition to that which is natively available at times of nil or low ambient light conditions, (eg: during times of precipitation, fog, lack of sufficient light). The Thoroughfare Illuminator of the Invention when it is used in a Street and/or Walkway category context, illuminates onto and/or near the category of Streets and/or Walkways broadly defined by reference to IP Australia's Corporate Street types (1), which include Roadway types and Pedestrian Walkway types such as: an " Access, Alley, Alleyway, Amble, Anchorage, Approach, Arcade, Artery, Avenue, Basin, Beach, Bend, Block, Boulevard, Brace, Brae, Break, Bridge, Broadway, Brow, Bypass, Byway, Causeway, Centre, Centreway, Chase, Circle, Circlet, Circuit, Circus, Close, Colonnade, Common, Concourse, Copse, Corner, Corso, Court, Courtyard.

This IP Australia list (1) would normally be used to comply with Australia Post address standards as "Postal Addresses". Thoroughfare Illuminators of the Invention illuminate onto and/or near other Thoroughfares not listed, which may be a "non-postal-address" type Thoroughfare. Some "non-postal-address" type Thoroughfares are absent from the list (eg: a railroad, 11 tramway or pike). A pedestrian-only walkway may be found alongside other Thoroughfares as above, or may be distal from other Thoroughfares including: Boardwalks, Foot bridges, Wharves, Piers, Jetties, Paths, Pavements, Pedestrian ways, Sidewalks, Trails, Walks, and Walking tracks. There are some uncommon Thoroughfare "types" which are referenced above and are not normally considered as types of Thoroughfares of the Invention, eg: Anchorage, Copse, Port, and Tarn. These lists are not to be taken as exhaustive. The Thoroughfare Illuminator of the Invention includes Illuminators that illuminate onto and/or near the Roadway groups and/or Walkway groups listed above, whether used by vehicles, pedestrians or both, and for simplicity in their descriptions we refer to "Roadways" for predominately vehicular movements, and "Walkways" for predominately pedestrian movements, and that they may be major or minor in their function, open ended and/or closed-ended (eg: Cul-de-sac, Court, Walk). The word "Thoroughfare" as used in "Thoroughfare Illuminator" of the Invention is not restricted to a throughput/throughway type of Roadway and/or Walkway. The Thoroughfare Illuminators of the Invention will be installed on Thoroughfares that are predominately used by pedestrians, vehicles or a combination of both, but should not be seen to be limiting the scope of the Invention by this list of users. There are usually three recognised categories of lighting requirements around Thoroughfares ("Thoroughfare Lighting"): Street lighting, Area lighting, and Walkway lighting (used predominately by Pedestrians). In the category of Street lighting, Wikipedia (5) defines a Street Light as: "A street light, lamp post, street lamp, light standard, or lamp standard is a raised source of light on the edge of a road or walkway, which is turned on or lit at a certain time every night. Modern lamps may also have light-sensitive photocells to turn them on at dusk, off at dawn, or activate automatically in dark weather. In older lighting this function would have been performed with the aid of a solar dial. It is not uncommon for street lights to be on posts which have wires strung between them, such as on telephone poles or utility poles..." 12 The first category of Thoroughfare Lighting listed is Street lighting. Wikipedia (5) defines the three main functions for a Street Lighting as: Beacon lighting, Roadway lighting, and Security lighting. The Thoroughfare Illuminator of the Invention excludes the first function, Beacon Lighting, as this is "Conspicuity" Lighting and is not considered to be a Thoroughfare Illuminator of the Invention. We include by reference, the Inventors' Australian Innovation Patent 2012101883 titled "High Efficiency Conspicuity Device" which describes within, a Conspicuity Light as being a Lighting Device that attracts attention to itself rather than to illuminate a distal place such as an area and/or surface, as is the case with the Thoroughfare Illuminator. Thus, Roadway lights and Security lights remain as the two functions of Street Light categories as they relate to the Invention. Looking at the second function of Street lighting; Roadway lighting; there are two groups, Major road lighting ("higher" vehicular traffic flow) and Minor road lighting ("lower" vehicular traffic flow). The first group, Major road Lighting, provides an illuminated environment that is conducive to a safer and easier movement of vehicles primarily. To accomplish this, it is necessary to illuminate the Thoroughfare to a sufficient level to reveal specific features mainly on the roadway. The second group, Minor road Lighting, provides an illuminated environment that is conducive to a safer and easier movement of pedestrians primarily. To accomplish this, it is necessary to illuminate the Thoroughfare to a sufficient level to reveal specific features mainly for the Pedestrian, and to a lesser degree for vehicles. The function(s) of Roadway Lighting is not normally intended to illuminate a vehicle's driving route (vehicle headlamps are preferred), but to reveal signs and hazards outside of a vehicle's headlamp beam(s) (or "headlights"). Certain dangers may emerge such as the significant reduction of night vision by a vehicle driver because of the accommodation reflex of their eyes and is of great importance because as vehicle drivers emerge from a lower illuminated area and move into a significantly higher illuminated area, their pupils quickly constrict to adapt from a more scotopic vision to a more photopic vision due to the brighter light, but as they later leave the area of brighter illumination and move back to an area of lower illumination, the dilation time of their pupils as they re-adjust to the lower light (scotopic vision) is much slower (than from scotopic to photopic) so they may be driving with a temporarily impaired vision. As a vehicle driver ages, their ability to discriminate and handle changing illumination levels 13 decreases and their recovery from impaired vision time increases, which may lead to increased dangers. Because of these dangers, the function of Roadway lighting is properly used sparingly and only when a particular situation justifies decreasing the risk. This usually involves a Roadway intersection with several turning movements and much signage. That is, situations where drivers must take in much information quickly that is not necessarily directly in the headlamps' beams. In these situations (eg: exiting a freeway exit ramp) the turnoff should be sufficiently illuminated so that vehicle drivers can quickly identify hazards, and a well-designed Roadway illumination plan will have gradually increasing illumination for approximately a quarter of a minute of travelling time before the hazard, and gradually decreasing illumination after. Main stretches of highways outside metropolitan areas tend to remain un-illuminated to preserve a vehicle driver's night vision and increase the visibility of oncoming headlights. If there is a sharp curve where headlights will not illuminate the road ahead, a light with illumination to the outside of the curve is often justified. If it is desired to illuminate a Roadway (perhaps due to heavy and fast multi-lane traffic) it should not be illuminated intermittently as this requires repeated eye re-adjustments which may cause eye-strain and temporary impaired vision when repeatedly passing through alternately illuminated areas. This is usually achieved with illumination designed to give a consistent light along the vehicle driver's driving route. Looking at the third function of Street lighting, Security lighting, Wikipedia (4) defines Security Lighting as: "In the field of physical security, security lighting is often used as a preventive and corrective measure against intrusions or other criminal activity on a physical piece of property. Security lighting may be provided to aid in the detection of intruders, to deter intruders, or in some cases simply to increase the feeling of safety. Lighting is integral to crime prevention through environmental design...". Security lighting can be used in residential, commercial, industrial, institutional or military settings and is usually illuminated all night. Some security lights may be activated by the use of a sensor (eg: Passive Infrared sensor) and be turned on when an intruder is detected. Security lighting can often help to prevent confrontational situations, and Security lighting often gives pedestrians better visibility when the need arises. Security lighting is often installed in a fixed position to illuminate onto and/or 14 near property structures to aid in the visual detection of pedestrians, whether invited onto the property or not. Quite often this is achieved by orientating the Illuminator to affect an optimal coverage of illumination onto and/or near a portion of property. Once installed and optimally orientated, the Illuminator is normally permanently lifetime situationally fixed in position. Unless the security illumination requirements of the property situationally change, there is no need to re-orientate the Illuminator. The second category of Thoroughfare Lighting is Area lighting, where the lighting is designed to provide an illuminated environment where the visual requirements of pedestrians are dominant and is usually in an outdoor environment. In both the functions of Public area lighting and Private area lighting the design of the lighting is such that the transition of the pools of light from dark to light is minimised. This type of lighting is found for example in parks and areas where there is human and/or vehicular activity. The third category of Thoroughfare Lighting is Walkway lighting, where the function of the Illuminator is to provide illumination on a Pedestrian Thoroughfare. Pedestrian Thoroughfares include, eg: Pedestrian walkways, pathways, tracks, and can be found in most Public parks, public accessible scenic bushland areas and places of Public interest away from roadways. Some walkways may not necessarily be "through-ways" but may have a dead end; eg: a walkway to a popular tourist viewing point or lookout at the top edge of a cliff-face that is often visited at night-time by Pedestrians; but are still considered a Thoroughfare of the Invention. The Thoroughfare Illuminator of the Invention is a "permanently lifetime 'situationally fixed' in place" Illuminator that illuminates onto and/or near a Thoroughfare in a normally fixed orientation. During the lifetime of its situationally fixed orientation, the Thoroughfare Illuminator is permanently fixed in place and is not normally moved. That is, the Illuminator when operationally installed in a particular situation remains fixed and operates in a normally fixed orientation for it's situational lifetime, and illuminates on and/or near a Thoroughfare. Eg: When a Street light is installed (eg: to a pole arm of a Street light pole), the Illuminator may be adjusted and aligned during the installation (prior to being operational), to allow for the illumination to be optimally oriented and then normally remain fixed in that fixed orientation for the permanent situational lifetime of that Illuminator. If the Illuminator is not permanently and situationally lifetime fixed in 15 place after installation, then it is not considered to be an illuminator of the Invention. The Illuminator may be re-orientated at some future time after installation for maintenance purposes or for a change in the Illuminator's situation, but remains permanently fixed and illuminates onto and/or near its Thoroughfare. An Illuminator that illuminates onto and/or near a Thoroughfare for only a non-permanent brief or temporary period (eg: at a roadworks, or a street party) is not an Illuminator of the Invention. Typical examples of Thoroughfare Illuminators are shown in fig 1 (1-4): Elevated Pathway lighting, suspended Street lights 1, Public Park Security lights 2, tall mast highway lighting 3, public courtyard light 4, gateway lighting, bollard lighting along a popular walking track and may also include area lighting for docks, ramps, wildlife areas etc. The examples 1, 2, 3, and 4 of Thoroughfare Illuminators that have their Lamp(s) attached in a fixed position with respect to their Illuminator's Housing when operationally installed, produce a normally fixed orientation (usually in a downward direction) of illumination with respect to the Thoroughfare's surface. By way of contrast, Stadium lighting towers, an example of which is shown in fig 1(5), often have adjustable Illuminators that can be rotationally adjusted by pivoting or "swinging" the Illuminator in one or more directions with respect to the horizon to change the Illuminator's orientation of illumination in either elevation and/or azimuth directions. These adjustable Illuminators in Stadium lighting towers would normally be expected to be re-orientated quite often during the different uses that the Stadium may have. Stadium tower lighting Illuminators illuminate onto a Stadium's ground, which is not normally a Thoroughfare, and thus Stadium Lighting towers that do not usually have a fixed orientation and that do not illuminate onto a Thoroughfare, are not considered to be within the definition of the Thoroughfare Illuminator of the Invention. Likewise, an Illuminator that illuminates onto eg: a Sports Oval, Velodrome, Sports Arena, Amphitheatre, etc (this list of non Thoroughfare public entertainment areas is not exhaustive and not limiting), and does not normally illuminate with a normally permanent situationally lifetime fixed orientation onto a Thoroughfare, is not an Illuminator of the Invention. Modern prior art LED Illuminators mostly use HB LED Lamps. HB LED Lamps are readily available and their most evolved efficiency rivals that of other high efficiency Lamp technologies with respect to their efficacy (e.g., High Intensity Discharge (HID) Lamps with efficacies of 90-1201m/w, but mostly around 1001m/w). Fig 14 displays an 16 exemplary modern 400w HID Lamp emitting about 45,0001m (=1 121m/w) and which is able to be fitted to a Thoroughfare Illuminator fig 15. Common, commercially available, mass produced, conventional HB LEDs also have about 1001m/w of luminous efficacy. Though some new models recently released have an efficacy of about 1301m/w (Cree XP-G2, 2012), although not at full output. Fig 18 depicts a graph of Efficacy versus Time for electric Lamps, showing the increases in efficacy in electric lighting over the past 100 years. There is a significant jump in efficacy in recent years for White LEDs. As increases in light output and efficiency are continually sort by Lamp manufacturers, modern HB LED Lamps are quickly becoming the preferred lighting source of today. For example, their "Green Credentials" are preferred over the prior art, e.g. incandescent and HID Lamps. However, there are limitations to light density output in HB LEDs. With HB LED technology there often comes a trade-off in design considerations. Even though today's commonly available mass-produced HB LEDs can produce efficacies of about 1001m/w, these optimum efficacies are not produced at the HB LEDs' highest power. Usually the optimum efficacy is at a much lower power than the maximum power for the HB LED, some times as low as only 25% of the maximum allowable safe power. Increasing power by increasing electrical current to the HB LED leads to the efficacy decreasing sharply to a point where increasing the current does not increase light output. Any increase in current beyond this point only acts to produce more heat (wasted power). The efficacy at this point is far lower than at the optimum efficacy. This effect is well known to those skilled in the art and is referred to as HB LED "Droop". A standard prior art HB LED Illuminator usually requires Optics to concentrate the HB LED's emitted light into a shaped beam. In the example of an Illuminator depicted in fig 10, the Optic may be in the form of a reflector 18, or could be in another example a lense, a plurality of lenses or reflectors or a combination of these. When a reflector is used it is usually of a predominantly parabolic mathematical shape, made of either vacuum metallised injection moulded plastic or aluminium, or spun or pressed aluminium that may be anodised and/or polished and/or vacuum metallised. Some reflectors are even made of glass when the requirement is for high heat resistance and specialized optical coatings. 17 In certain prior art models as in fig 16, multiple HB LED Chips are used and in these cases each HB LED Chip may have it's own reflector and/or optics which may be either separately mounted to each HB LED Chip or plastic moulded in a group to enable easy assembly and alignment. In the case where lens optics are used, a design using Total Internal Reflection (TIR) is commonly used to focus the output beam narrowly and efficiently, as well as reducing the overall optics size. This special type of lense uses TIR to act as both a reflector and a lense thus minimising overall dimensions. A recent development in the area of Non Imaging Optics is the Simultaneous Multiple Surface (SMS) design method. Use of this fairly complicated and heavily mathematical method can result in almost 100% maximum light control to very narrow angles. There are various types of SMS methods, but in the case where a narrow formed beam is required of a prior art Illuminator, the smaller angles often sought (say 5-10 degrees) result in very large lenses in the order 20 to 25 size multiples of the original HB LED's die diameter as well as very significant thicknesses which can result in manufacturing difficulties. We define the types of Non-Laser Low-Polar HEHB LED die(ce) used in the Invention as being "Non-Laser Non-Polar and Non-Laser Semi-Polar, HEHB LED" die(ce) and to be collectively referred to as "Low-Polar HEHB LED die(ce)". Improvements have recently been made in the HB LED(s) arena. Non-Laser Low-Polar High Efficiency High Brightness LEDs (HEHB LEDs) have been shown to have brightness increases of over 400% over current technology conventional HB LEDs of similar size. That is, a similar light output is emitted from a Low-Polar HEHB LED die over four times smaller than the conventional HB LED die. A HB LED die(ce) emitting area reduced in the order of 75+%, results in a width reduction of about 50+%. Such a reduction in the HB LED's size makes for very significant reductions in optics size, as well as increased efficiency in light beam output and control. 18 Referring to figs 26-31, we show the parabola's optical paths in 2-D view with a reduced number of light rays, whereby light is only projected forward from the source (simulating a real life use of a HB LED), being a point 63 in fig 26 and fig 27, a semi wide light source 67 in fig 28 and fig 29, and a wide light source 70 in fig 30 and fig 31. The edge of the reflector 64 is the delineating point on the reflector's diameter/length that determines the limit of where light rays either bounce off the reflector or emerge directly without hitting the reflector's surface. To show the affects of HB LED widths, we show in fig 26, fig 28, and fig 30 only the light rays emitting from the HB LED surface that bounce off the reflector and then emerge 65, 68, and 71, and in fig 27, fig 29 and fig 31 we show all rays, that is, rays coming from the HB LED surface and bouncing off the reflector 65, 68, and 71 as well as light rays that emerge directly from the HB LED surface and emerge without hitting the reflector's surface 66, 69, 72. As can be seen from fig 26 and fig 27 the theoretical point source of light 63 at the parabola's focus is the best "behaved" when used in a parabolic reflector, that is, the light emerging from the parabola's focus 63 and hitting the reflector will always project straight forward as mathematically defined. As the light source becomes wider 67 and wider 70 the light beam outputs become more and more complex and unfocussed, leading to extremely difficult optical design problems and/or significant loss of efficiency in light output. A similar but more complex problem exists when lense optics are used, and in general the larger the reflector(s) and/or the lense(s) optics the tighter the beam output and more efficient the output. The use of Low-Polar HEHB LEDs as the light source in the Invention's High Efficiency Thoroughfare Illuminator allows for the optical problems to be significantly reduced or virtually eliminated by the inherent nature of the smaller Low-Polar HEHB LED die'(s) physical widths, resulting in increased light efficacy (lumens), higher quality light beam spread, and reduced optics sizes. We provide a brief description of the Low-Polar HEHB LED die(ce) used in the Invention. Prior art HB LED die(ce) suffer from in-efficiencies in light production due to internal inefficiencies, defects and dislocations within the HB LED die's active light producing region(s). One cause of the inefficiencies is the "piezoelectric induced and intrinsic 19 polarization" (Polar) effects in type III-nitride-based (eg: Gallium Nitride (GaN)) crystal structures which have typically been grown on a C-plane type substrate which creates "Polar" electric field effects within the resulting structure. The typical growth process of creating prior art HB LED die(ce) using a C-plane type substrate (eg: Silicon Carbide, Sapphire) structure can create strong intrinsic and induced electric fields (piezoelectric) within the die structures (including the light emitting active regions), and reduces the ability to produce light emission from the die's active region(s), i.e. by the Quantum Confined Stark Effect (QCSE) within quantum wells. One way that these "Polar" effects can be greatly reduced, along with a significant reduction of many dislocations and defects, is by growing the devices on Non-Polar planes of a type Ill-nitride-based structure (eg: A Non-Polar plane of GaN type crystal structure) instead of the more commonly used Polar C-plane crystal structure. For example, in a Non-Polar plane of GaN type structure which contains equal numbers of Ga and N atoms the plane is "charge-neutral", or "without polarity". Further Non-Polar layers that are laid down epitaxially are the same to one another, so the crystal(s) are not polarized along these growth directions. To the Inventors' best knowledge, as of late 2012, there are two such known groups of symmetry-equivalent Non-Polar planes in type Ill-nitride-based (eg: GaN type) structures. They are the {11-20} group, the "A planes", and the {1-100} group, the "M-planes". Another way to reduce or even eliminate the polarization effects in type Ill-nitride-based (eg: GaN type) structures is to grow the structures on Semi-Polar planes of type III nitride-based (eg: GaN type) structures. The term Semi-Polar planes in the context of the Invention refers to planes within a (eg: GaN type) hexagonal type crystal structure(s) where such planes possess two nonzero "h", "i" or "k" Miller indices, and a nonzero "I" Miller index. The more often referred to Semi-Polar planes include the {1 1-22} (R Plane), {10-11}, and {10-13} planes. A Semi-Polar plane's electric field vector lies at an oblique angle to the plane's surface normal, hence reducing any full Polar effect within the plane. Non-Laser LED die structures epitaxially grown from Non-Polar or Semi-Polar type III nitride-based structure base-substrate crystals produce a high efficiency LED dice with very little or no "Polar" affected light producing active regions. These LED dice can be used to produce Low-Polar HEHB LED Chips and are referred to as Non-Laser Non 20 Polar or Non-Laser Semi-Polar, HEHB LED Chips as appropriate. These Non-Polar or Semi-Polar, Non-Laser HEHB LED Chips have a much higher light density output (eg: 400+ % increase) than "Polar" type HB LED Chips because of the higher efficiencies in the active regions of these LED Chip's dice. The High Efficiency Thoroughfare Illuminator of the Invention is a significant improvement on prior art Illuminators used in Thoroughfare Illuminators. Low-Polar HEHB LEDs will be the preferred light source for Thoroughfare Illuminators and do not suffer many of the internal in-efficiencies of prior art "polar" HB LEDs. The Thoroughfare Illuminator of the Invention uses a Low-Polar HEHB LED(s) which contain at least one Low-Polar HEHB LED die(ce). The Invention teaches those skilled in the art how to produce a more efficient Thoroughfare Illuminator. Benefits of the Invention As LED technology is rapidly gaining momentum as the "Green" and preferable lighting source for today and the future, this technology is the most preferred for its Green Credentials. Low-Polar HEHB LEDs utilize low voltage power requirements and may be designed such that the Lamp, as well as any Lamp socket connector used, will limit dangers associated with high voltage devices that were found in poorly designed prior art Lamp sockets. Eg: When personnel need to work on them to replace a failed Lamp. Increasing the efficiency in lighting designs is called for as the commercial cost of energy, especially electrical energy, is increasing at alarming rates and lighting manufacturers are seeking more efficient means to produce light emission. As Low Polar HEHB LEDs can produce over 400% more light for the same size as a conventional HB LED, there are benefits that are quickly recognised. The use of State of the Art Low-Polar HEHB LEDs Technology has a three prong advantage over the use of earlier art light source technologies. 21 Firstly, when a Lamp has a higher lumen output density over prior art Lamps of similar size, then designs associated with that Lamp may lead to reduced thermal design challenges. Low-Polar HEHB LED Lamp Modules of the same brightness as prior art HB LED Lamp Modules often require a smaller heat sink design which reduces thermal design criteria when used in the High Efficiency Thoroughfare Illuminator's Housing. Often there are also the benefits of lower heat management requirements. Secondly, the Invention allows for a much higher Lamp brightness than ever before for the same size light source, whereby this gain is achieved without normally increasing the physical size of the LED Lamp Module, the High Efficiency Thoroughfare Illuminator Housing, and/or the optical components but rather by increasing the light density output of the light source, in this case using the Low-Polar HEHB LEDs of the Invention. Thirdly, the reduced size of a Low-Polar HEHB LED Chip(s) when compared to a similar brightness conventional HB LED Chip(s) allows for a relatively more compact Lamp Module size if needed. The more efficient Low-Polar HEHB LED die(ce) can replace multiple single die HB LED die(ce) and often quite large multi-die HB LED COB Arrays. We use the following examples to demonstrate the huge improvement that may be gained by the use of the Low-Polar HEHB LED Chip(s). Fig 17 depicts an artist's impression of how two conventional HB LED Lamp Modules 26, 27, using conventional HB LED Chips compare with similar light output Low-Polar HEHB LED Lamp Modules 28, 29 using Low-Polar HEHB LED Chips. This representation (not to scale) gives an example of what reduction there may be in the required number of LED dice required for the similar light outputs. 28 can replace 26, and 29 replaces 27. The examples shown are used for comparison only. There are other benefits. LED Lamps are not as prone to failure due to vibration or sudden physical shock as are filament Lamps. Lifetime expectancies for LED Lamps are typically 10,000-30,000 hours and more. This could greatly simplify the Lamp design, as there would not necessarily need to be a provision or "socket" to allow for a replaceable Lamp in some designs. The increased light output benefits mentioned and simpler design criteria lend nicely to the Green Credentials of the Invention. Any saving in power consumptions due to the 22 use of higher light output LEDs results in less energy required powering the Lamp, hence more efficiency, less power used equates to less carbon dioxide (CO 2 ) emissions. Summary of the Invention Described herein is the use of Low-Polar HEHB LEDs as the preferred choice of light source for the Thoroughfare Illuminator of the Invention. The Illuminator's design has high efficiency, incorporates proper thermal management to allow for a long serviceable life and incorporates the use of Low-Polar HEHB LED(s). The Invention provides means to significantly improve on most prior art Thoroughfare Illuminators and will allow designers of such lighting to adopt state of the art technology using Low-Polar HEHB LEDs. The use of Low-Polar HEHB LEDs will be the preferred light source in the State of the Art lighting and is a significant leap forward in Thoroughfare Illuminator design. Detailed Specs and preferred embodiments We first describe in detail the Low-Polar HEHB LED's typical physical structure. A typical prior art non-laser white light output HB LED as depicted in fig 24, is usually comprised of at least one die which in turn is manufactured from several substrate layers. The light producing Active Layer 52 is normally a layer containing Gallium Nitride (GaN) (and/or AIGaN, InGaN) with various substrate layers above 48, 49, 50, 51 and below 55, 56, 57 this layer 52. Electrical connection to the die is normally via an Anode fine gold wire to the p-electrode 48 and a Cathode fine gold wire to the n-electrode 53. Electrical current through these connections results in electron flow producing photons (light) from the GaN type light producing layer 52. The bonding layers of Indium Tin Oxide (ITO) 49, 54 allow the electrode layers 48, 53 respectively to be electrically bonded to the structure(s). In the GaN light-producing layer of standard prior art GaN fig 24 with crystal growth starting with for example, a Sapphire (A1 2 0 3 ) substrate 57 in the C-plane 59 crystal growth direction 58, (the 2 most commonly used Polar substrates are Sapphire and 23 Silicon carbide), quantum wells grown along this axis 58 exhibit high piezoelectric fields due to the hexagonal lattice symmetry without a centre of inversion. This results in electrons and holes being pulled to the opposite sides in quantum wells resulting in greatly reduced efficiency eg: QCSE. Additionally, lack of purity, dislocations, defect concentrations, droop, and colour shift contribute to a reduced luminous efficacy of most prior art light HB LEDs to be limited to the range of 90-110 lumens/watt maximum. Low-Polar HB LED dice significantly reduce or eliminate these problems, and the "Low Polar" terminology naming comes from the description of the arrangement of the crystal planes in the Type Ill-nitride based light emitting crystal structures and how they are fabricated/manufactured/cut/used in a Low-Polar HB LED die. We elaborate further, in a crystallographic sense, the definition of Low-Polar Planes to be those planes in GaN crystals to be the fully Non-Polar, and including the Semi-Polar, and whereby the Low-Polar plane(s) in a Low-Polar HB LED die may be cut/produced at an angle up to +0.0/- 1.5 degrees, for one or more of the three principal axes (X, Y, Z). The principal axes X, Y, Z are analogous to the principal planes as follows: C-axis @ Z axis, M-axis @ Y-axis, A-axis @ X-axis. Referring to fig 25, the most commonly referred to GaN type crystal planes are shown namely the standard polar(ized) C-plane {0001} 59, the A-plane {1 1-20} 61 and M-plane {1-100} 62 non-polar planes, and the R-plane {1 1-22} 60 semi-polar plane. There are other Semi-Polar planes eg: {10-11}, {10-1-1}, {10-1-3}, {10-13} as well, but the C, A, M, and R are the most commonly referred to crystallographic planes in GaN type crystal structures, and by our definition above, the A, M, and R planes are Low-Polar. Waltereit et al. (3) in the year 2000 were the first researchers to demonstrate an absence of a piezoelectric field in GaN/AIGaN in the non-polar M plane. Park and Chuang (2) noted in the year 1999 that certain semi-polar planes can eliminate or nearly eliminate the piezoelectric field. To keep the description brief we will concentrate on the aforementioned common planes, as those skilled in the art of GaN A3N epitaxial heterostructure optoelectronic research and design should recognize that they are a good representation of the field of research and design. 24 Research in the past few years has shown solutions to the problems of manufacturing low-polar GaN LED dice, and Abramov et al. (Foreign patent RU 2006103270) teaches the use of Langasite that is a natural non-polar crystal that can be used as a substrate base for producing low-polar GaN. By utilizing a low-polar type III-nitride based (eg: GaN) light producing layer (or active layer), the polarization and piezoelectric effect is minimized or not present, resulting in increased lumen efficacy, greater lumen density in the range of 400%+, minimal droop at high temperatures and currents, increased heat resistance and minimal colour shift. It is noted that a High Efficiency Thoroughfare Illuminator's light source may use a coloured output non-white light emitting HB LED that uses other chemistry mixes, including alloys of Gallium. Eg: Infrared LEDs may use Gallium arsenide (GaAs) or Aluminium Gallium arsenide (AIGaAs); or where a UV emitting HB LED may use Aluminium Gallium Indium Nitride (AIGaInN), a yellow HB LED may use Aluminium Gallium Indium Phosphide (AIGaInP) in its active layer(s). The most common "colours" are infrared, red, orange, yellow, green, blue, violet, and ultra violet (UV). To keep the descriptions brief we will refer to typical structure types and alloys/mixes where Gallium is used, as GaN "type" structures. There are many other type Ill-nitride chemistries, including alloys of Gallium, that may be used to produce different coloured light emissions, as well as the combined use of multiple LED die(ce) of different output colours that may be individually powered to produce a variable coloured light as desired. The descriptions and examples given should not limit the scope of the Invention in any way. In the first preferred embodiment depicted in fig 19, a High Efficiency Thoroughfare Illuminator is described with three individual but connected Lamp sections each containing the following: heat sink ribs portion 31, LED Lamp Module segment mounting surface 32; LED Lamp Module segment containing an LED Lamp Module Housing 33, LED Lamp Modules (containing nine Low-Polar HEHB LED Chips 35 and the LED Lamp PCB 36); reflector 37, Lamp Cover 38. In this particular embodiment, each of the three LED Lamp Module segments (33+35(x9)+36) are attached to the front-side of the Illuminator's Housing 30 via the three mounting surfaces 32 by a removably attached (non-permanent) twist-lock means in addition to a thermally conductive non-permanent paste compound (such as Arctic Silver paste), to enable a safe, secure, thermally 25 managed and operated LED Lamp Modules. As illustrated in fig 19, the three LED Lamp Module segments (33+35(x9)+36) each contain an LED Lamp Housing 33 having a typically planar shaped inner LED Lamp PCB mounting surface 34 to facilitate the attachment of an LED Lamp Module 36+35(x9). In each of the three segments the LED Lamp Housing 33, being constructed of an aluminium alloy, and aiding in the removal of excess thermal energy from the rear of the Low-Polar HEHB LED Chips 35(x9), passively via the LED Lamp PCB 36, the LED Lamp Housing 33, the Illuminator's Housing 30 and the heat sink ribs portions 31(x3) to the environment, and have each allowed for the fixing of the LED Lamp PCB 36 to their surfaces 34. Being of an aluminium alloy, the LED Lamp Housings 33(x3) and the Illuminator 's Housing 30 have an extremely high thermal conductivity and emissivity due to the inherent properties of aluminium and its alloys, especially in the anodised state. The Illuminator's Housing 30 and LED Lamp Housings 33(x3) are typically moulded using a die-casting technique. The Illuminator's Housing 30 and LED Lamp Housings 33(x3) also have an inlet aperture/hole for a power cable to transfer power to the Low-Polar HEHB LED Chip(s) 35(9x3). The three Lamp Covers 38 and three optics reflectors 37 are removably attached allow replacement of the LED Lamp Module segments 33+35(x9)+36 at end of-life or as required. On the rear-side of the Illuminator's Housing 30 there is an attachment provision 39 for attachment of the High Efficiency Thoroughfare Illuminator to a fixture such as an elevated support, in this case a pole arm of a Thoroughfare lighting pole, to provide a fixed orientation of illumination onto and/or near a Thoroughfare when operationally installed. In the second preferred embodiment as illustrated in the perspective exploded view of fig 20, the High Efficiency Thoroughfare Illuminator's Housing 40 has a front-side surface 41 that is shaped to fit an LED Lamp PCB 43. The LED Lamp PCB 43, with attached Low-Polar HEHB LED Chips 42(x9), is permanently attached to the surface 41. The attachment is by screw means and is additionally aided with a thermally conductive adhesive (eg: the commercially available Arctic Ceramic Adhesive). The LED Lamp Module 42(x9)+43 is permanently lifetime attached. The LED Lamp Module 42(x9)+43 is protected and covered by the Lamp Cover 45. (Note: The Illuminator's Power Inlet is not shown, but is the Illuminator's mounting hole). The illumination pattern or distribution from Low-Polar HEHB LED Module(s) of a High Efficiency Thoroughfare Illuminator may benefit from the use of a reflector or multiple 26 reflectors and/or a lens or multiple lenses or combinations of reflectors and lenses, and stating that there is an infinite number of combinations of shapes, sizes, materials and configurations that could be designed into a High Efficiency Thoroughfare Illuminator's reflectors and/or lenses for it's required light distribution pattern is understood by those knowledgeable in the art. The design and materials used in the High Efficiency Thoroughfare Illuminator take into account the environment that the High Efficiency Thoroughfare Illuminator is to be used in, eg: It is recommended that a High Efficiency Thoroughfare Illuminator used predominately in a position which is exposed to the elements or the weather would be designed to have an Ingress Protection rating of no less than IP66. The "IP" Code (Ingress Protection Rating, sometimes also interpreted as International Protection Rating) consists of the letters "IP" followed by two digits or one digit and one letter and an optional letter. As defined in international standard IEC 60529, IP Code classifies and rates the degrees of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in mechanical casings and with electrical enclosures. As the life of the High Efficiency Thoroughfare Illuminator is usually of a longer lifetime than prior art Illuminators, cleaning cycles may have an important influence on performance. Cleaning of the internals of a standard prior art Thoroughfare Illuminator is usually done at the time of the (more frequent than a High Efficiency Thoroughfare Illuminator) Lamp replacement. It would be a desirable inclusion of a preferred embodiment of the High Efficiency Thoroughfare Illuminator to increase the IP rating to allow for reduced cleaning cycle requirements to IP68. With no or little apparent need to change the Lamp, there is no or little need to access the internals of the Illuminator and so in theory, the Illuminator could be sealed. This would improve the maintenance cycle as there would be less accumulated dirt ingress (eg: dust, insects, mould, moisture or condensation) and hence reduced the cleaning times. To further facilitate this, an Illuminator would also need to be kept "clean" externally for much longer periods and appropriate external surface shapes, textures and coatings may additionally be considered to enhance this feature in the High Efficiency Thoroughfare Illuminator's design. 27 The Low-Polar HEHB LED Lamp Module(s) of the Invention are not limited to just those producing visible light output of a Whitish colour. A white light LED for example may be considered a warm white (e.g. slightly yellowish and approx. 2600-3500 degrees Kelvin), neutral white (e.g.. mostly white and approx. 3500-5000 degrees Kelvin), or cool white (e.g. slightly bluish and over approx. 5000 degrees Kelvin) approximately, depending on their respective colour temperatures measured in degrees Kelvin. For example, a requirement for light of a different colour/wavelength (e.g. a reddish tint) is sometimes used in places where animals pass through at night so that human observers and/or cameras can watch the animals with minimal disturbance to the animals. Usually however, outdoor lighting is of a whitish colour. The visible light range for humans ranges in wavelength from about 430 nanometres (nm) for deep violet light up to about 850nm for red light. In the first preferred embodiment as depicted in fig 19, each of the three Lamp sections 31+32+33+35(x9)+36+37+38 contains a Lamp Cover 38 (only one variation is shown) that covers a portion of the High Efficiency Thoroughfare Illuminator's Housing 30 and parts and is so designed to permit transmission of light from the Low-Polar HEHB LED Chips 35(x9) as well as offer some mechanical protection to the internals of the LED Lamp Module 36+35(x9). This embodiment of the Illuminator has near "clear" Lamp Covers 38 to allow for light transmission to the outside (in another embodiment it may have a Lamp Cover with at least some degree of diffusive and/or translucent property to produce a more preferred light output for particular requirements). The shape of the Lamp Cover 38 is shaped to match the contour of the LED Lamp Module 36+35(x9) and other parts of the Lamp segment, including the reflector 37. It should be stated that some Lamp Covers may not intentionally be shaped "optically" and are for pure mechanical protection from the environment. The three Lamp Covers 38 in this embodiment are made from injection moulded UV stabilised, optical-grade polycarbonate (PC). In the second preferred embodiment as depicted in fig 20, a slightly translucent light diffusing Lamp Cover 45 made from injection moulded UV stabilised polycarbonate covers the Lamp's reflector 44 and PCB 43 with attached Low-Polar HEHB LED Chips 42(x9), and is so designed to permit transmission of a diffused light from the LED Lamp Module 42(x9)+43 as well as offer some mechanical protection. 28 In a further embodiment of the Invention a portion of the(se) Lamp Cover(s) could be clear for example, but more likely having a portion slightly translucent or slightly textured and that some degree of translucency is preferred over a pure "clear" Lamp Cover, though a clear Lamp Cover with little or no diffusive properties may be used for maximum light transmission ("clear" is defined in respect of the Lamp Cover as being relatively transparent to the preferred light colour temperature/wave-length that is generated by the Low-Polar HEHB LED(s) and translucent is defined as having a relative opacity to which light is not allowed to pass through of no more than 55 opacity units measured on a linear scale of 0 to 100 opacity units (where 0=transparent/clear and 100=opaque/blocked). Another embodiment would have a Lamp Cover manufactured from a normally clear resinous substance so moulded to be integrally/intimately attached (2+ parts "co injection moulding") moulded onto the Low-Polar HEHB LED(s) and encase the Low Polar HEHB LED(s) partly or as a whole. The resinous Lamp Cover described would act for example, as an optical light shaping member as well as being of a protecting nature. It is appreciated that there can be an infinite number of Lamp Cover shapes, some of which may incorporate light output modifying optics, and even tints or engineered coatings to enhance or attenuate specific wavelengths, and so it is stated that the preferable materials for the front transmission window or Lamp Cover would be selected from a UV stabilised polycarbonate (sheet or injection moulded), tempered glass, cellulose butyrate or propionate (for petrochemical protection). One particular design could use for example a Phosphors containing resinous layered Lamp Cover to act as a wavelength changing medium to allow light of a predominately different wavelength to emit than that of the Low-Polar HEHB LED(s) itself. (This is commonly referred to as a "Remote Phosphor" filter and may normally only be used in the absence of a photo phosphor layer or doping layer being absent from the Low-Polar HEHB LED die(ce)). In most cases involving Low-Polar HEHB LED Chips, an efficient heat conduction pathway should be established from the LED Chips to the environment via the use of heat conductive compounds and heat sink elements. 29 Heat conduction from Low-Polar HEHB LED(s) may be further aided by mechanical attachment of the LED Lamp Module to part(s) within the Illuminator, to create a thermal pathway to the heat dissipation (heat sink) portion(s) of the Illuminator Housing(s). The heat dissipation portion(s) of the Illuminator Housing(s) and the LED Lamp Housing(s) may include surface(s) designed with adequate surface area to allow adequate passive or dynamically forced thermal communication between the High Efficiency Thoroughfare Illuminator Housing and the environment to enable heat, by way of thermal energy transfer, to propagate from the Low-Polar HEHB LED(s), through the heat dissipation portion(s) of the Housing(s), to the environment. In the first preferred embodiment of fig 19, we show the heat dissipation heat sink ribs portions 31(x3) comprising a number of surfaces arranged in a way as to improve the thermal communication between the said surface(s) and the environment by increasing the amount of surface area available. This particular arrangement of surfaces is known as a Heat Sink and is familiar to those skilled in the art. Typically, a heat sink could normally be part of an overall moulding of an Illuminator's Housing. Apart from the shape and alignment of the ribs, fins or other structure(s) of the heat sink, a typical design should take into account the efficiencies of a passive heat sink or could be designed to utilize a forced thermal transfer between an Illuminator Housing and the environment. An embodiment that takes advantage of forced air movement principles on a heat sink by way of a forced air movement device may use a dynamic air-moving device such as a rotating fan or a pulse operated air movement device such as the commercially available "Synjet" fig 21 that has no large dynamic moving parts. It should be noted that other forms of "cooling" could be used. Many surface finishes for the High Efficiency Thoroughfare Illuminator are available and typically, a design of the High Efficiency Thoroughfare Illuminator's Housing may require a special treatment to suit a particular environment, use, or trend. The LED Lamp's Housing, if required, due to the outputted thermal power of the Low-Polar HEHB LED(s) used, may have a portion of its exterior surface coated in a substance so as to aid in its mechanical and environmental protection and not to significantly hinder heat convection/radiation from the heat dissipating portion(s) of the High Efficiency Thoroughfare Illuminator. This protective layer(s) or substance may also act to enhance 30 the aesthetic nature or appearance of the High Efficiency Thoroughfare Illuminator as well as providing a corrosion inhibiting function(s) on any alloy that may be used in its construction. This substance could be an appropriate paint, an electrolytically applied coating/conversion, (for example anodising in the case of an aluminium alloy), or any other appropriate applied finish(es). Where the Illuminator's Housing is predominately a plastic (eg: UV stabilised glass-filled Polycarbonate), the surfaces of the said Housings may have a smooth or textured feel and/or appearance to fit in with the overall Illuminator's purpose, function, outward appearance or theme. When exposed to sunlight for example, a plastic may need to be stabilised against the affects of UV radiation. In the first preferred embodiment depicted in fig 19, the three LED Lamp Modules 35(x9)+36 are able to be connected to an appropriately designed and constructed PCM(s) which is/are typically located in circuit between the power source to the High Efficiency Thoroughfare Illuminator and at least one of the Lamp's LED(s) Chip(s) 35. In most cases of High Efficiency Thoroughfare Illuminators, the PCM would accept power from a directly connected external power supply (e.g. a 230vac supply of a typical Australian mains power supply), and supply by its design, the correct current form, voltage and/or current to power the Low-Polar HEHB LEDs Chip(s) within the Illuminator. The PCM would typically mounted to the High Efficiency Thoroughfare Illuminator near to the Lamp(s), or remotely from the High Efficiency Thoroughfare Illuminator but being able to still supply the correct power to the Lamp's LED(s) Chip(s). A High Efficiency Thoroughfare Illuminator may have more than one power supply source (such as a mains supply and a battery supply/solar powered supply), and each power source may have its own PCM attached between the power source and the Illuminator's Low-Polar HEHB LED chips. The lowest level/amount of power (form, voltage and current) required to illuminate an LED die to an effective illumination level must also be of a level so as not to cause premature deterioration or failure of the LED's die. An LED die can deteriorate considerably and have a greatly reduced lifetime when "driven" at too low a power, as well as too high a power. A minimum level at where the LED die will not be greatly adversely affected is defined. This level of illumination is referred to as the "minimum effective threshold of illumination" for any given die. The LED die also has a maximum effective threshold that relates to the amount of illumination produced from the 31 maximum level of safe power (form, voltage and current) that an LED die is designed to use before there is premature deterioration or failure. The range of power between these two limits is defined herein as the "Effective Operating Power Range" (EOPR) of the LED. Without limiting the design, it is stated that the PCM may for example, be at least one or more electronic component(s) mounted to a PCB(s) and acting preferably as a constant current delivering module (eg: Buck, boost, buck-boost, SEPIC, etc) or it may be at least a single component acting as a power regulator (such as a simple linear current device). The Lamp's LED(s) die(ce) would utilise the EOPR power form from an appropriately designed power supply either directly, or via a PCM which has the ability to modify the power requirements to the Lamp should it be required. Most prior art Illuminators used outdoors usually utilize "mains" voltage power as a power source. A requirement of a Lamp using Low-Polar HEHB LED technology may be the need to be able to work when installed in unison with an earlier prior art Thoroughfare Illuminator and its pre-existing electrical setup, and may be electrically controlled by a standard "triac" style dimmer control. The PCM in this example, would modify the power input from the mains voltage ac power source directly or via a step down transformer or ballast, and modify the PCM's output so as to be a constant current power source which is required for the Low-Polar HEHB LED(s) of this example. One example of a PCM to do this would be an electronic PCB utilizing the Texas Instruments LM3445 triac dimmable offline LED driver solution delivered by Texas Instruments. The LM3445 LED driver enables a direct replacement of an incandescent or halogen Lamp that is currently interfaced to a TRIAC dimmer without having to change the original infrastructure or sacrifice performance. Fig 22 illustrates a schematic diagram of one preferred design utilising the LM3445 driver IC 46. Fig 23 shows an example of a PCB utilising the LM3445 LED driver 47. Placement of the Low-Polar HEHB LED(s) PCM is important as it may generate its own heat and this thermal mass must, like the Low-Polar HEHB LED's operating thermal mass, be controlled, attenuated or managed and/or kept within recommended limits. An 32 attachment to a suitable surface of the Illuminator's Housing (or bonding of the PCM to the Illuminator's Housing) usually suffices. Low-Polar HEHB LED(s) has/have a requirement for a PCM to supply the required power form but not necessarily be placed or fixed in any particular fixed location or position relative to the Low-Polar HEHB LED(s) and that the requirement is that the PCM is placed at least, somewhere electrically in circuit between the power supply and at least one of the Low-Polar HEHB LED(s) of the LED Lamp Module. In another embodiment it would be a preferred requirement that there be a means to sense the temperature(s) of the PCM, and the Low-Polar HEHB LED(s). The usual methods acknowledged by those skilled in the art are to use either thermistors, and/or analogue (or digital) Integrated Circuit (IC) sensors. These operate by maintaining an appropriate "feedback" to the PCM of the temperatures at the placement zones of the Lamp components, and so allow the PCM, in it's design, should it be required, to moderate the output current load to the Low-Polar HEHB LED(s) to reduce the power load of the system and so in turn, bring the operating temperature(s) down to a safe level. This works to ensure that the Low-Polar HEHB LED(s) do not have a shortened life expectancy, and parts of, or parts adjacent to the High Efficiency Lamp are not thermally damaged. A further feature is the ability to modify the light output strength, as full brightness may sometimes be too illuminating. This would most preferably be performed by modifying the current to the Low-Polar HEHB LED(s), and in most cases this is usually accomplished by Pulse Width Modulation (PWM) of the LED's PCM output to the Low Polar HEHB LED Module(s).
