Electrical light set circuit, light strip and control apparatus therefor

A light-emitting electrical apparatus comprising:

• a) a set of at least four LED light sources and a plurality of control signal lines, first and second ones of the LED light sources being polarized and connected in reverse polarity with each other between two of the control signal lines, a third one of the LED light sources being polarized and connected between one of the first and second ones of the LED light sources and an additional control signal line of the plurality of control signal lines, whereby:
• i) one of the first and second LED light sources is independently selectively activated when opposite signals are applied between the first and second control signal lines with the third control signal line being kept in a floating state;
• ii) the other of the first and second LED light sources is independently selectively activated when the signals are reversed with the additional control signal line remaining in the floating state;
• and
• iii) the third LED light source is independently selectively activated when opposite signals are applied between the one of the two LED light sources and the additional control signal line, the other of the two control signal lines being kept in a floating state;
• b) a housing assembly having a casing and a back plate, the first, second and third light sources being mounted on the back plate, the casing having a top wall and a luminous cavity formed between the back plate and the top wall, a side wall of the casing extending between the top wall and the back plate, at least 12 of the LED light sources being spaced and proximate the side wall;
• and
• c) means for directing light from ones of the LED light sources to exit the casing in particular directions for producing predetermined lighting effects, comprising the casing being formed of a transparent or translucent material, at least some light emitted from the LED light sources exiting the side wall of the casing, the casing further comprising an expansion ring extending outwardly from a lower portion of the side wall for receiving some of the light exiting from the side wall.
