Abstract
A housing is inserted from the rear side of a case having an indicating plate. The housing has a plurality of illuminating cells corresponding to the indicating plate, and a plurality of bulb insertion holes communicating with the illuminating cells, respectively. A common electrode plate passes through the vicinities of the bulb insertion holes while a plurality of control electrode plates pass through the vicinities of the bulb insertion holes opposite to the common electrode plate. A plurality of bulbs are inserted in and engaged with the bulb insertion holes and are electrically connected to the common electrode plate. One end of each of a plurality of wires are electrically connected to the control electrode plates.
Claims8
An indicator lighting unit which is inserted from a rear side of a case having an indicating plate and which is for illuminating said indicating plate from the rear side thereof to provide indications, said indicator lighting unit comprising:
- a one-piece modular housing inserted from the rear side of said case, said housing having a plurality of illuminating cells corresponding to said indicating plate and a plurality of bulb insertion holes communicating with said illuminating cells, respectively;
- a common electrode plate passing through the vicinities of said bulb insertion holes, said common electrode plate being directly mounted on said housing;
- a plurality of control electrode plates passing through the vicinities of said bulb insertion holes, said control electrode plates being directly mounted on said housing;
- a plurality of bulbs inserted in and engaged with said bulb insertion holes and electrically connected to said common electrode plate and said control electrode plates;
- a first wire having one end electrically connected to said common electrode plate;
- and
- a plurality of second wires each having one end thereof electrically connected to said control electrode plates;
- whereby said housing may be easily mounted and removed from said case.
An indicator lighting unit which is inserted from a rear hole of a meter case with an indicating plate and which is for illuminating said indicating plate from a rear side of said indicating plate to thereby provide indications, said indicator lighting unit comprising:
- a one-piece modular housing inserted from the rear hole of said meter case, said housing having a plurality of illuminating cells corresponding to said indicating plate and a plurality of bulb insertion holes communicating with said illuminating cells, respectively;
- a common electrode plate passing through the vicinities of said bulb insertion holes, said common electrode plate being directly mounted on a wall of said housing;
- a plurality of control electrode plates passing through the vicinities of said bulb insertion holes, said control electrode plates being directly mounted on the wall of said housing;
- a plurality of bulbs inserted in and engaged with said bulb insertion holes and electrically connected to said common electrode plate and said control electrode plates;
- a terminal electrically connected to said common electrode plate;
- a first wire having one end electrically connected to said common electrode plate through said terminal;
- and
- a plurality of second wires each having one end electrically connected to said control electrode plates.
