Portable reduced-emissions work light
A reduced emissions work light includes a bulb with an elongated bulb tube. A handle is provided adjacent the bulb, and is adapted for being gripped by a user to manipulate the work light. An emissions containment housing is located within the handle. A ballast is located within the housing, and is operatively connected to the bulb. An emissions filter is located within the housing, and is operatively connected to the ballast. The filter and housing cooperate to reduce emissions generated by the work light.
1. A reduced emissions work light, comprising:
(a) a bulb comprising an elongated bulb tube;
(b) an electromagnetic interference emissions containment housing located adjacent to said bulb;
(c) an electronic ballast located within said emissions containment housing and operatively connected to said bulb;
(d) an electromagnetic interference emissions filter operatively connected to said electronic ballast;
(e) a power supply cord adapted for being connected to a power source to supply electrical power to said work light, the power supply cord extending from a first end of the containment housing through the length of the containment housing to a second end of the containment housing; and
(f) an emissions-insulating sheath positioned around the power supply cord to reduce electromagnetic emissions by the power supply cord when supplying electrical power to the work light, whereby the cumulative effect of the containment housing, electromagnetic emissions filter and power cord sheath results in a light meeting applicable military requirements for control of EMI emissions for lights having electronic ballasts.
2. A reduced emissions work light according to claim 1 , and comprising a tubular, light-transmitting bulb shield surrounding said bulb tube to protect said bulb from damage.
3. A reduced emissions work light according to claim 2 , and comprising a cylindrical shock-absorbing plug positioned within said bulb shield and engaging a free end of said bulb tube to further protect said bulb from damage.
4. A reduced emissions work light according to claim 3 , wherein said plug includes an interior web for being gripped to remove said plug from said bulb shield.
5. A reduced emissions work light according to claim 2 , and comprising a shock-absorbing end cap positioned over an end of said bulb shield.
6. A reduced emissions work light according to claim 1 , and comprising a switch opening formed in said emissions containment housing to accommodate a ballast activation switch.
7. A reduced emissions work light according to claim 1 , and comprising a removable color filter positioned over said bulb shield to filter light emitted by said bulb.
8. A reduced emissions work light according to claim 1 , and comprising a light reflector located adjacent said bulb tube for enhancing illumination of said bulb.
9. A reduced emissions work light according to claim 1 , and comprising an elongated pull strip releasably attached to said bulb for removing said bulb from said work light for replacement.
10. In combination with a mobile shelter system erected to create a covered interior, a portable reduced emissions work light adapted for illuminating the interior of said shelter system, said work light comprising:
(a) a bulb comprising an elongated bulb tube;
(b) an electromagnetic interference emissions containment housing located adjacent to said bulb;
(c) an electronic ballast located within said emissions containment housing and operatively connected to said bulb;
(d) an electromagnetic interference emissions filter operatively connected to said electronic ballast, whereby said emissions filter and emissions containment housing cooperate to reduce electromagnetic interference emissions generated by said work light;
(e) a power supply cord adapted for being connected to a power source to supply electrical power to said work light; and
(f) an emissions-insulating sheath positioned around the power supply cord to reduce electromagnetic emissions by the power supply cord when supplying electrical power to the work light, whereby the cumulative effect of the containment housing, electomagnetic emissions filter and power cord sheath results in a light meeting applicable military requirements for control of EMI emissions for lights having electronic ballasts.
11. A combination according to claim 10 , and comprising a tubular, light-transmitting bulb shield surrounding said bulb tube to protect said bulb from damage.
12. A combination according to claim 11 , and comprising a cylindrical shock-absorbing plug positioned within said bulb shield and engaging a free end of said bulb tube to further protect said bulb from damage.
13. A combination according to claim 12 , wherein said plug includes an interior web for being gripped to remove said plug from said bulb shield.
14. A combination according to claim 11 , and comprising a shock-absorbing end cap positioned over an end of said bulb shield.
15. A combination according to claim 10 , and comprising a switch opening formed in said emissions containment housing to accommodate a ballast activation switch.
16. A combination according to claim 10 , and comprising a removable color filter positioned over said bulb shield to filter light emitted by said bulb.
17. A combination according to claim 10 , and comprising a light reflector located adjacent said bulb tube for enhancing illumination of said bulb.
18. A combination according to claim 10 , and comprising an elongated pull strip releasably attached to said bulb for removing said bulb from said work light for replacement.
