Problem to be solved: to reduce the effect of the external force applied to the outer lead wire located outside the bulb to the connection portion between the lead wire and the other elements in the case of manufacturing the incandescent lamp, and to prevent the occurrence of the failure of...
FIGURE 5.Schematic diagram. The corresponding schematic for my final circuit is shown inFigure 5. I used three incandescent light bulbs of the type you find in car brake lights and connected them in parallel (more on lamp selection later). These light bulbs can handle large currents and are ...

1. An incandescent bulb luminance matching LED circuit for causing the luminance of a light emitting diode to match the luminance of an incandescent bulb, comprising: an input port; an output port; at least one light emitting diode; and ...
and the chromaticity point of the color of the emitted light that is dispersed and absorbed by the structure exists in the range of chromaticity that is surrounded, in the CIE1976 u' v' chromaticity diagram, by (u', v')=(0.33, 0.485), (0.31, 0.517), (0.28, 0.51), (0.265, 0.5),...
light chromaticity value at an early stage of lighting is within a region surrounded by a point C1 (x:0.6500, y:0.3250), a point C2 (x:0.6750, y:0.3250), a point C3 (x:0.7024, y:0.2976), and a point C4 (x:0.6855, y:0.2945) in the CIE chromaticity diagram, and which is ...
Incandescent light sources have been used for many years in lighting fixtures. An incandescent light source, such as an incandescent light bulb, includes a filament, which when heated emits light. The filament in the incandescent bulb typically emits a light with a color temperature of about 3000...
A lighting system has a lighting fixture with a white light source and a color light source, a control circuit pulses the white and color light sources and changes relative duty cycles of the light so
