Abstract
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.
Claims21
A reduced emissions work light, comprising:
- (a) a bulb comprising an elongated bulb tube;
- (b) a handle adjacent said bulb and adapted for being gripped by a user to manipulate said work light;
- (c) an emissions containment housing located within said handle;
- (d) a ballast located within said housing and operatively connected to said bulb;
- and
- (e) an emissions filter located within said housing and operatively connected to said ballast, whereby said filter and housing cooperate to reduce emissions generated by said work light.
A reduced emissions work light, comprising:
- (a) a flourescent bulb including electrode pins, a pin base, and an elongated bulb tube extending outwardly from said pin base;
- (b) a handle adjacent said bulb and adapted for being gripped by a user to manipulate said work light;
- (c) an emissions containment housing located within said handle, said housing comprising a hollow cylindrical metal cup;
- (d) a ballast located within said cup and operatively connected to said bulb;
- (e) a ballast activation switch accessible through an opening formed in said cup to activate said ballast at said handle;
- and
- (f) an emissions filter located within said cup and operatively connected to said ballast, whereby said filter and housing cooperate to reduce emissions generated by said work light.
A reduced emissions work light, comprising:
- (a) a bulb comprising an elongated bulb tube;
- (b) a perforated, emissions insulating screen surrounding said bulb tube;
- (c) a handle adjacent said bulb and adapted for being gripped by a user to manipulate said work light;
- (d) an emissions containment housing located within said handle;
- (e) a ballast located within said housing and operatively connected to said bulb;
- and
- (f) an emissions filter located within said housing and operatively connected to said ballast, whereby said filter, housing, and screen cooperate to reduce emissions generated by said work light.
A reduced emissions work light, comprising:
- (a) a bulb comprising an elongated bulb tube;
- (b) a perforated, emissions insulating screen surrounding said bulb tube;
- (c) a light-transmitting bulb shield surrounding said bulb tube and screen to protect said bulb from damage;
- (d) a handle adjacent said bulb shield, and adapted for being gripped by a user to manipulate said work light;
- (e) an emissions containment housing located within said handle;
- (f) a ballast located within said housing and operatively connected to said bulb;
- (g) an emissions filter located within said housing and operatively connected to said ballast;
- and
- (h) a power supply cord adapted for being connected to a power source to supply electrical power to said work light, said power supply cord including an emissions insulating sheath, whereby said filter, housing, screen, and sheath cooperate to reduce emissions generated by said work light.
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) a handle adjacent said bulb and adapted for being gripped by a user to manipulate said work light;
- (c) an emissions containment housing located within said handle;
- (d) a ballast located within said housing and operatively connected to said bulb;
- and
- (e) an emissions filter located within said housing and operatively connected to said ballast, whereby said filter and housing cooperate to reduce emissions generated by said work light.
