The present invention technically relates to lamp systems and methods. More specifically, the present invention technically relates to ultraviolet lamp systems and methods. Even more specifically, the present invention technically relates to ultraviolet lamp systems and methods involving a keying device.
Manufacturers and agencies associated with the lighting industry have developed standard lamp bases (incorporated into the lamp assembly itself) and corresponding lamp holders. The basis for these related art bases and holders is to provide the market with standardized products for facilitating a competitive environment where multiple lamp manufacturers and lamp fixture manufacturers could develop and sell interchangeable components that met the basic needs of the lighting market. Standard lamp base standards, including, but not limited to, T5, T8, Tb, T12, 2G7, 2G1 1, G23 and GX23, as designated for lamps manufactured by Philips Lighting™ and others, may have been developed as common standards to facilitate the implementation of lamps into various applications. Manufacturers have developed many different lamp models based on these standard lamp bases.
In many applications, the lamp base standards serve the industry well. However, in certain applications, utilization of the standard lamp base configurations can be detrimental. Typically, different model lamps manufactured on one particular lamp base standard vary greatly in terms of lamp voltage, current, illumination and power rating. This condition may present problems with respect to proper and safe usage of lamps with certain lamp fixtures. “Blind” utilization of the standard lamp bases by manufacturers within lamp fixtures creates a situation where the lay person consumer or user may easily, potentially, and unknowingly, implement the wrong lamp type for the device employed. Sometimes lamp models with different power and current ratings utilize the same apparent configuration, e.g. Philips Lighting™ Model Nos. TUV36WPLL and TUV60WPLL, which only serves to increase the probability of an incorrect lamp implementation by the user.
Another problem in the related art lamp devices may be in their performance. Lamp power is often critical to the performance of the system employing the lamp. For instance, where lamps are used for non-illumination purposes, including germicidal applications, the effective dosage of the system may be predominately affected by the power of the lamp being utilized. Utilization of the incorrect lamp in such systems results in failure of the system to achieve critical dosing, which may be required and/or specified. This may result in the device failing to meet the specified performance.
Yet other problems in the related art are unreliability and liability. The reliability of the device employed can be adversely affected by the implementation of the incorrect lamp. Impedance differences associated with different lamp models can induce problems with an employed system. Reliability and liability issues surrounding misapplication of lamps may include implementation of an incorrect lamp which causes premature lamp failure, thereby resulting in loss of performance and breach of warranty. Furthermore, implementation of an incorrect lamp may cause premature ballast (power supply) and controller failure, thereby also resulting in loss of performance and breach of warranty. Implementation of an incorrect lamp can cause operation of a device to go outside of acceptable thermal and electrical limits. This condition can result in loss of performance, breach of warranty, and personal injury liability. Also, as discussed in the preceding sections, the implementation of an incorrect lamp resulting in diminished dosage performance may result in injury, especially in germicidal applications, and personal injury liability claims by the consumer.
Yet another problem in the current art is related to marketing. In many cases, an advantage to the manufacturer and provider of equipment exists in requiring replacement parts to be distributed through their own channels of distribution. With a standard lamp base and fixture, replacement lamps may come from any source; and the channels of distribution and sales cannot be assured.
Some manufacturers may have made, or deferred to, the decision to offer products that rely primarily on the knowledge of the user and the utilization of the standard lamp bases to ensure the proper continued operation of their systems in application. This strategy may result in a potential misapplication of their systems, although it may provide a lowest cost approach for the initial device sale and also in lamp replacement sales.
Yet another problem can occur which creates a safety issue. Fluorescent lamps for illumination are currently manufactured and sold with the same lamp configuration and base as germicidal lamps. Due to increased sales of UV germicidal fixtures for treating air in commercial and residential HVAC systems, UV germicidal lamps are sold through marketing channels available to consumers. An unknowing consumer could actually buy a germicidal lamp from a retail store and place it in the receptacle of a normal fluorescent illumination lamp fixture, thereby creating a dangerous situation. Fluorescent illumination fixtures do have the safeguards and carry the warnings associated with UV fixtures. Of utmost concern, UV lamps can be harmful to the skin and the eyes. What is needed is a system that may address these and other problems associated with lamp fixtures and assemblies.

Advantages of the present invention include preventing person injury and minimizing breach of warranty, increased performance, and increasing reliability. Other features of the present invention are disclosed, or are apparent, in the section entitled “Mode(s) for Carrying-Out the Invention,” disclosed, infra.
For better understanding of the present invention, reference is made to the below-referenced accompanying Drawing. Reference numbers refer to the same or equivalent parts of the present invention throughout the several figures of the Drawing.
The key 30 may be configured such that only certain types of lamp assemblies are utilized with fixture assembly 12. In this manner, only certain predetermined and/or preconfigured lamp assemblies are utilized with particular fixture assemblies. This feature decreases the likelihood that improper lamp assemblies can be utilized with particular fixture assemblies, setups, and lamp systems. With this configuration only proper lamp assemblies are operatively coupled with the fixture assemblies. Thus, the use of incorrect lamp assemblies for the particular application, configuration, and/or fixture assembly is reduced or eliminated in the present invention.
The fixture assembly 12 comprises at least one material such as a polymer, a plastic, a metal, a ceramic, and a composite, or other materials, as desired, such as are used in existing lamp fixture assemblies. The key 30 is made from plastic, metal, or other materials, as desired, as well as from metal, such that it may slightly flex and allow coupling of lamp assembly 20 to fixture assembly 12.
The base 22 comprises at least one material such as a polymer, a plastic, a metal, a ceramic, and a composite, or other materials, as desired, such as are currently utilized for lamp bases. Electromagnetic energy source 26 may be incandescent, ultraviolet, or any other type of electromagnetic energy source. Other electromagnetic energy sources may be utilized for other applications, as desired.

The more detailed views of the fixture assembly 12 and the key 30 are shown in
The extending portion 32 is configured to extend over a portion of the fixture assembly 12 such that it will extend into a receptacle portion 16 of fixture assembly 12, which may be configured to receive a lamp assembly. Furthermore, the key 30 may include a base engaging portion 36, which may be configured to engage a portion of lamp assembly and/or allow lamp assembly to operatively couple to fixture assembly 12. Utilizing this key configuration, only predetermined or preconfigured lamp assemblies may be utilized with a fixture assembly. Receptacle portion 16 may be configured to couple to a base portion of a lamp assembly to allow the lamp assembly to operatively couple to the fixture assembly.
The base engaging portion 36 of the key 30 may be configured to fit into the recess 24 and may be placed within the system at different positions to allow different types of lamp assemblies to be utilized with a single fixture assembly. Similarly, the receiving structure 24 may be positioned at different positions adjacent to the lamp assembly. Different positions for receiving structure 24 may be utilized with different types of lamp assemblies to reduce the likelihood that a user will install an improper lamp assembly into a fixture. With this configuration, and position of the key 30, the lamp assembly 20 may operatively coupled with a fixture assembly such that it will illuminate and operate properly.
With this configuration, the key 30 may be utilized with existing fixture assemblies, such that only certain lamp assemblies may be utilized within a lamp system and the fixture assemblies. Furthermore, current lamp assemblies may be modified to allow operative coupling to proper, predetermined fixture assemblies, such that a user may be less likely to install an improper lamp assembly in a particular lamp system and/or fixture.
Additionally, systems may be originally configured to include keys and/or the receiving structure 24, or other configuration to reduce or eliminate the use of improper replacement lamp assemblies with a particular fixture assembly. In this manner, lamp assemblies that do not produce a desired result may be reduced or eliminated from use when a user is replacing the lamp assembly within a lamp system. This may be particularly important when a certain type of ultraviolet lamp or other type of lamp must be utilized for a particular configuration and/or utilization, such as in a disinfection system, which may require certain wattages, etc. for proper operation.
The lamp assembly 20 may also include electrical contacts 28, which may be configured to electrically couple with corresponding electrical contacts (not shown) of the fixture assembly 12. The electrical contacts 28 provide a pathway for an applied current to flow to the electromagnetic radiation source 26, whereby the source 26 is powered, when the lamp assembly 20 is operatively coupled with the fixture 12.

While the embodiment illustrated shows but a single protrusion or base engaging portion, to be associated with the receiving structure 24, more than one slot and/or key may be utilized for various applications, as desired. Additionally, while a specific configuration of a receiving structure 24 and a base engaging portion 36 has been illustrated and described, it the slots and accommodating protrusions may take various polygonal and geometric shapes and all such matters are within the contemplation of the present invention.
With respect to the lamp, the exemplary embodiments of the present method and system impart an inexpensive solution for customizing standard lamp bases and for minimizing the probability of lamp misapplication in systems. The resulting lamp configuration incorporates coupling configurations, including, but not limited to, a slot or recess in addition to the normal geometric aspects of standard lamp base, including, but not limited to, standard lamp bases designated as 2G11, 2G7, G23, GX23. This coupling configuration allows a corresponding and reciprocal key, rib, or post to operatively engage the corresponding lamp base, holder, or fixture. However, other configurations may be utilized as desired.
With respect to the lamp holder, the exemplary embodiments of the present method and system include an inexpensive configuration for customizing existing commercially available lamp holders, bases, and fixtures that may minimize lamp misapplication. The resulting lamp fixture configuration incorporates a receiving structure, including, but not limited to a rib, bracket. or post, into the mating surface(s) in addition to the normal geometric aspects of a particular standard lamp base as between the lamp and lamp holder. This receiving structure may correspond to the additional and corresponding receiving structure adjacent to the lamp base as above noted.
The incorporation of the receiving structure, in addition to the normal geometric attributes of the standard lamp base type, may create a physical interference to prevent normal installation of an improper lamp into this fixture. The lamp may be effectively matched or “keyed” for fitting in the corresponding lamp fixture. However, this receiving structure may also allow the implementation of a lamp base that has the appropriate reciprocal interference relief features. With this configuration, the lamp device manufacturer may provide a cost effective system to end users that may minimize the opportunity for misapplication of lamps within the lamp device.
The present method M1 of fabricating a lamp keying system 10 generally comprises the steps of: providing a lamp base 22 including a recess at one end; providing a lamp support 45, having a lamp support receptacle 44, being detachably coupled to the lamp base 22, and including a first portion to receive the lamp base 22 and a second portion being recessed away from the received lamp base 22; and providing a lamp keying device having one of the following configurations: (a) a keying device comprising at least one base protruding key 41 being formed on, affixed to, or detachably coupled with, the base 22 and at least one support slot 42 being formed in the lamp support receptacle 44, the at least one base protruding key 41 detachably coupling with the at least one support slot 42; (b) a keying device comprising at least one support protruding key 43 being formed on, affixed to, or detachably coupled with, the lamp support receptacle 44 and at least one base slot 24 being formed in the base 22, the at least one base slot 24 detachably coupling with the at least one protruding support key 43; and (c) a keying device comprising at least one base protruding key 41 being formed on, affixed to, or detachably coupled with, the base 22 and at least one base slot 24 being formed in the base 22, the keying device further comprising at least one complementary support protruding key 43 being formed on, affixed to, or detachably coupled with, the lamp support receptacle 44 and at least one complementary support slot 42 being formed in the lamp support receptacle 44, the at least one base protruding key 41 detachably coupling with the at least one complementary support slot 42, and the at least one base slot 24 detachably coupling with the at least one complementary protruding support key 43.
This invention may establish a method M2 for “keying” a lamp and lamp holder to minimize the potential for misapplication of lamps within a lamp fixture, i.e., the method of using the lamp keying system. The method M2 provides for implementing unique mechanical features in standard lamp assemblies and lamp fixtures/holders/receptacles. The features provided may be a “male to female” coupling relationship between the two components, i.e., the lamp base and the lamp receptacle, and may be unique for minimizing the possibility for incorporation of an incorrect lamp into an existing fixture. However, other configurations may be utilized, as desired. This method may incorporate mechanical interference into the lamp fixture which prevents the insertion of a lamp that does not have the proper and corresponding interference relief feature.
With this configuration, existing lamp fixtures and lamps may be modified to prevent misapplication of a lamp to a fixture and to insure that lamps of the various types are associated only with fixtures for which the lamp is intended to be used. Furthermore, exemplary embodiments may provide a methodology and a system for insuring that correct lamps are used in specific applications and that misuse may be eliminated or reduced by the provision of a keying element or elements.
