IV. the specific embodiment

Below will with the sports lighting, sports lighting fixtures and the sports lighting fixtures that are used for sports ground illumination as a setting (for example, shown in Figure 1A and 1C) embodiment of illuminating equipment is described.

A. exemplary means

1. prevent venting

Loss source from the light of illuminating equipment 10 is the decomposition of material in the illuminating equipment 10.For instance, light (particularly UV light) can make some material breakdown, and makes its venting.Can reduce or minimize the venting in the illuminating equipment 10 in the following way:

(a) in factory, carry out the assembling of illuminating equipment 10.Even fingerprint also can stay residue, these residues can reduce the efficient (therefore losing light) of light reflection or light transmissive surfaces, perhaps in the course of work of lamp, cause venting (this can stay the residue that condenses on reflecting surface or lens, and therefore stops that light penetrates from illuminating equipment).Assemble carefully in factory and can avoid on internal reflection surface producing foul or fingerprint.After factory finishes the assembling of illuminating equipment 10, before transporting it into the infield, seal it off, this setter that can reduce sports ground causes the risk of venting.Setter does not need the inside or the handling lenses 34 of contact illumination equipment 10.They only need take out illuminating equipment 10 from cargo compartment, avoid contact lens 34, and illuminating equipment 10 is installed on the suitable knuckle plate on the transverse arm 7.

(b) hole in the sealed illuminated equipment.It is useful equally that the opening that leads to illuminating equipment inside is sealed (only staying the filter that is used to carry out air exchange).Example comprises between opening part, lamp awl and the reflector framework in lamp awl, the packing ring between glass lens and the reflector framework.Specifically, in this exemplary embodiment, glass lens is arranged in metal lens frame 230, and this metal lens frame 230 can be installed in the peripherally ported shoulder of reflector framework 30, and adopts the packing ring 237 between metal lens frame 230 and reflector framework 30 to seal.Another packing ring 231 is sealed to glass lens 3 on the lens frame 230.In addition, if lens frame 230 has any seam or noncontinuity around lens frame, then comprise such structure, this structure guarantees that lens frame is without any the gap and keep its shape to avoid any gap.In addition, can lamp bore 40 and knuckle 50 between use packing ring and seal (in fact, can use several packing rings and seal) in different positions.

(c) hiding questionable material makes it not be exposed to light.For instance; lens frame packing ring 237 is sealed in lens frame or lens-mount 230 on the reflector framework 30; lens packing ring 231 is sealed in lens on the lens frame 230; and for recessed or be placed under the guard circle and stash, so that it is not exposed to major part (if non-all) direct light (particularly UV light).More particularly, illustrate as Fig. 4 E of the cutaway view of lens frame 230 and how to hide material and make it not be exposed to light.U-shaped lens packing ring groove 236 is admitted U-shaped lens packing ring 231 (Fig. 7 A and 7B).The metallic walls that limits groove 236 specially is designed to extend the terminal edge pleasure trip on foot enough distance of its terminal edge than packing ring 231, makes it not be exposed to the light that illuminating equipment directly penetrates from figure thereby packing ring 231 stashed fully.This structure makes can being minimized by zone or the part that light (particularly UV light) shines of packing ring 231 at least.To note the V-arrangement or the Y shape end of packing ring 231 in addition.This tip designs is for providing better sealing effectiveness when inserting glass lens 3 wherein, and is sealed in better on the inwall of groove 236.It is also noted that the ledge of Fig. 7 B middle washer 231 in addition, this ledge is positioned at the bottom of the inner glass edge receiving portion of packing ring 231.This also is the better sealing effectiveness that is designed to provide the edge of glass lens 3.

Another example is second packing ring 237 (referring to Fig. 4 E, the cross section of lens frame 230) that is adapted to fit in the groove 239 that cross section is a C shape.When from illuminating equipment, taking off glass lens and lens frame 230, the relative wall of C shape groove 239 keeps O-ring gasket 237 (referring to Fig. 5 A to 5D), and be configured to when lens frame 230 is installed on the reflector framework 30, this relative wall abuts by part with the projection or the seat that are formed in the periphery of reflector framework 30, thereby hiding fully packing ring 237 is so that its light that is not exposed to illuminating equipment and is produced.In addition, because metal lens frame 230 contacts with metal-metal between the solid metal reflector framework 30, the end of the relative wall of C shape groove 239 helps packing ring 237 is remained colder, thereby stops this packing ring venting.These are terminal or

abut position

227 and 228 and fully extend around lens frame 230, and because metal-metal contact and help heat is conducted to reflector framework 30 from lens frame 230 after installing.The size of reflector framework 30 and surf zone are as the radiator of the heat that conducts from lens frame 230.Packing ring 237 will compress and make it possible to carry out metal-metal and abut, and therefore can also fully hide packing ring 237.

(d) use the material of not exitting.An example is teflon Teflon ^TMCentring ring 112 (referring to Fig. 3 A and 3B).Figure 12 to Figure 18 illustrate illuminating equipment can be used for lens frame 230 is installed to various elements (comprising lens frame screw, lens ring rivet and other element) on the reflector framework 30, these elements are made of metal so can not exit.Fig. 8 to Figure 10 illustrates the hardware that lens frame 230 can be clipped on the reflector framework 30.Packing ring can use with locking bolt, but can use metal that it is covered, and makes great efforts to make it directly not to be exposed to UV light.Be well known that UV light can make some material outgassing.Temperature is also like this in addition.

(e) UV light is minimized.For instance, coating or the coating that absorbs, stops or reflect UV light can be applied on the arc-tube body, to stop the UV light at light source place.This coating is being known in the art.Can be referring to the U.S. Patent No. 6833675 of this jade-like stone company of agate, the content of this patent is included in this by reference.

(f) opening that only is used for air exchange in reflector framework 30 inside uses and contains carbon filter (Figure 19 A and 19B).If constant clean air venting still less then can occur by illuminating equipment 10.The opening that is provided with for filter (not expecting that by filtering the material of material constitutes) can be positioned on the periphery of reflector framework 30, and is less relatively, and directly is not exposed to light basically.

Have been found that this modification can significantly reduce the venting material in the lens inside of illuminating equipment and condensing of reflecting surface, this light that makes illuminating equipment 10 easily that condenses produces loss.So the minimizing venting will reduce the light loss along with the time, reduce maintenance capacity, reduce the energy input quantity, and may prolong the service life of lamp doublely.

Importantly has " cleaning " optical system.Even also may there be venting in the legacy device of this illuminating equipment.Silicone gasket, plastic components even glue also may be exitted.If illuminating equipment sealed, and take above-mentioned steps before being transported to the infield, can reducing venting significantly so.Setter may not can cause the problem of venting or minimizing light by the inside of operation illuminating equipment 10.In addition, in the factory-assembled process, the cover protection reflection insert peeled off on the highly reflective reflection insert 120 makes residue can not occur that on reflecting surface this residue may stop light or venting subsequently.

The another kind of optional method of attempting to reduce light loss is to stop dust or foul or other material or particle to accumulate on the lens.Similar Rain-

(commercial product Texas) can be applied on the lens 34 with thin layer form for Sopus Products, Houston, to reduce the accumulation of dust and foul.At more commercial films that can obtain to have identical function.Commercially can obtain other hydrophobic coating or or coating.Reduce dust and foul and the light loss of illuminating equipment 10 can be reduced several percentage points, and therefore be increased in the light that shines the place under the situation of using identical energy.Stop material to be attached to and on glassly will reduce this material or the caused reflection of particle.This reflection is actually uncontrollable, therefore can cause dazzle.

Said structure and step can advantageously combine with making the minimized manufacturing technology of venting.For instance, assembling illuminating equipment 10 in the environment of plant of control rationally, but not assemble in the place of illuminator (" building " environment), can reduce the foul, impurity and other material that adhere to or enter illuminating equipment 10 so significantly.Compare with the outdoor environment at the place, building place of building the outdoor sport illuminator, the environment of plant approaches " clean room (clean room) " a little.Can train the workman when the element of assembling illuminating equipment, to carry out careful operation, to avoid foreign matter attached on internal part or the surface.Even fingerprint or stain also may influence reflecting surface unfriendly.Greatly reduce the possibility that pollutes and to the Effect on Performance of illuminating equipment 10.These steps have been eliminated much may disadvantageous changing factor to the performance of illuminating equipment 10.The workman can assemble illuminating equipment 10 and seal its inside in factory.The recessed packing ring and the use of other material, avoid the deterioration of optical system with assembling process and environment, optical system may be exitted or absorption or reverberation (and therefore loss shines the light of object space or produces dazzle or the astigmatism of overflowing) in uncontrolled mode.Give the workman with this manufacture professor easily, and between each illuminating equipment, realize reproduction easily.Therefore, has the conforming high performance reproducibility of realization.Also allow the assembling workman to carry out complicated combination in addition, and the workman needn't have complicated knowledge aspect how acting in element and feature.Can reduce labour cost like this.Another feature is that the lens packing ring has the metal-metal contact, thus from its heat radiation (its bigger surface of using the reflector framework is as radiator), and stopping that light arrives the lens packing ring, the irradiation of heat and light all can cause venting.Be exposed to the also complete thermal insulation of illumination with the lens packing ring and compare, can realize that significant temperature reduces.Example be the metal frame that makes the supporting glass lens with the solid metal reflector framework between carry out metal-metal and contact.Between glass lens and lens frame, can use relatively thin packing ring, but the metal-metal contact can utilize the bigger surface of reflector framework outwards to conduct heat as radiator from glass lens.

Be higher than in the baking oven of its normal working temperature by die casting reflector framework being put into temperature (for example, Fahrenheit 450 degree), can before assembling illuminating equipment 10, make the venting of reflector framework.

B. assemble and use

Other parts (comprising top specifically described those parts) are assembled, assembling with each illuminating equipment 10 of finishing given illuminator, comprise that the assembly with lens 34 and shield 70 is locked on the reflector framework 30, and the whole holes of sealing except that the appointment opening that is used to place filter.The assembling workman takes adequate measures to be attached to or to be positioned at the inside of reflector framework 30 to avoid any foreign matter after lens 34 and shield 70 are installed on the reflector framework 30 hermetically.This comprises the disengaging sheet material protective cover on the high reflectance insert that divests reflector framework 30 and shield 70.

The bar that illuminating equipment 10 and top is provided with pre-assembled transverse arm 7 is transported to the place that will throw light on aiming figure, and how illuminating equipment that aiming illustrates each pre-design aims at respect to the place.Whole system can be assembled in advance in factory basically, just (referring to the U.S. Patent No. 5600537 of this jade-like stone company of agate, the content of this patent are included in this by reference) such as the pedestal of bar and bar, transverse arm, illuminating equipment, distribution, ballast boxes.This pre-assembled system can be from this jade-like stone company of agate with trade name LightStructure ^TMObtain.

C. optional form and alternative form

Can recognize that the exemplary embodiment of front only is illustrative rather than restrictive.The present invention can comprise conspicuous for those skilled in the art distortion.Scope of the present invention only is subjected to the qualification of claims.

For instance, can expect the variation of size, material and various combinations by the present invention.Specifically, in order to produce useful or favourable result, do not need all features and the aspect of exemplary embodiment.

1. the application scenario substitutes

The present invention can be used for the illumination application scenario in other the big zone except that sports lighting.Several examples wherein comprise parking lot illumination, architectural lighting, public place illumination, arena or stadium lighting.The present invention can be applied to room lighting.This relates to any HID illuminating equipment of the controlled convection light of needs.This comprises the target that illuminates relatively remote (for example, about 100 feet or farther) or is used for the special efficacy illumination.

2. other optional form, alternative form and notion

Can recognize, the present invention proposes the discovery that can produce significant advantage.As previously mentioned, in sports lighting, the invention solves luminous flux (lumen) decay of small form as example.

With reference to the accompanying drawings as can be seen, except known fluorescent tube luminous flux attenuation, the present invention can solve the potential source of one or more different luminous flux attenuation, in the fluorescent tube luminous flux attenuation, along with the passage of working time, the output of the light of lamp reduces according to predictable function.

Therefore, can recognize that the present invention can have various ways and embodiment.Except reducing the fluorescent tube luminous flux attenuation, a step in can the implementation method step reduces light loss with auxiliary.Perhaps, can implement the combination of disclosed substantive step, these are combined in the potential ability that in most cases will have the luminous flux attenuation that further reduces illuminating equipment.

A kind of method is to design carefully and material that selection is used with illuminating equipment, particularly those with illuminating equipment work in heat energy or luminous energy contacts or the material that influenced by it.Fig. 3 A and 3B illustrate the proprietary material that is used for centring ring 112 (Figure 14 A and 14B).Figure 19 A and 19B illustrate the reflector ventilation filter, select its material to stop venting or not exit.Other view illustrates packing ring or other examples of material, if select these materials inadequately, may cause venting.

Secondly, can manufacture and design number of assembling steps reducing or eliminating the material that may cause luminous flux attenuation, or even the careless and inadvertent material that is caused.

The 3rd, the design of the structural cooperation of the parts by illuminating equipment, can be with element of exitting easily and the energy that may cause exitting isolated or cover.

From accompanying drawing, can see, a kind ofly be used for hiding material and make it not be exposed to UV light and make heat as described below with the technology that reduces or eliminates some material outgassing away from material.A lot of traditional illuminating equipments use single washer sealing lens.As shown in Figure 4, the geometry of lens frame 230 uses packing ring and another O-ring gasket of a sealing reflector in the U-shaped groove.Be actually a packing ring that to use and be divided into two.The geometry of the quoit of supporting glass is not only hidden packing ring makes it not be exposed to the UV radiation, and produces the metal-metal contact, and this contact can be conducted heat away from quoit, and can be with spread heat in the reflector framework.This is a part that also therefore reduces the measure of venting away from heat.
