    摘要： A cold cathode fluorescent lamp includes a glass bulb (16), a protective film (22) formed on an inner face of the glass bulb, and a phosphor layer (24) that overlaps the protective film and that contains blue phosphor particles (26B), green phosphor particles (26) and red phosphor particles (26). The glass bulb has been formed from soda glass, and the blue phosphor particles have been coated with a metal oxide (30). Also, the protective film is made of silica (SiO2). Since the protective film has been provided in the fluorescent lamp and since the blue phosphor particles, which readily deteriorate, have been coated with the metal oxide, a good luminance maintenance rate is obtained. In addition, although the glass bulb of the fluorescent lamp is made of soda glass, since the protective film is made of silica, the fluorescent lamp obtains an initial luminance equivalent to the initial luminance of a fluorescent lamp whose glass bulb is made of borosilicate glass.

    摘要： A lighting device includes: a lighting unit for supplying a lighting power to a light source unit; and a controller, for controlling the lighting unit. The lighting unit has an inductor and a switching element, and a diode for flowing a flyback current of the inductor to the light source unit during an OFF period of the switching element, and the controller has a unit for intermittently driving an ON/OFF operation of the switching element by a PWM signal and a unit for driving the switching element by a frequency higher than that of the PWM signal during an ON period of the PWM signal, and when the PWM signal falls, the controller reduces a peak value of a load current flowing through the light source unit during a certain period.

    摘要： A light emitting element lighting device includes: a rectifying unit which rectifies an AC voltage; a smoothing unit which smoothes a ripple voltage from the rectifying unit; a power supply unit having a switching element; and a control unit which controls on/off of the switching element. Further, the smoothing unit servers as a partial smoothing circuit for partially smoothing a low voltage period of the ripple voltage outputted from the rectifying unit. The power supply unit supplies a lighting power to a light source unit including one or more light emitting elements. The control unit controls a switching frequency of the switching element to decrease as the output voltage of the smoothing unit decreases.

    摘要： A lighting apparatus includes: a lighting circuit; a dimming signal circuit; and a feedforward control circuit. The lighting circuit receives an output which is rectified and smoothed commercial power, and supplies power to a light source Lamp. The dimming signal circuit sends a timing signal to the lighting circuit, wherein the timing signal is a signal for switching an output of the lighting circuit periodically to an ON state and either of an OFF state and a dimmed state. The feedforward control circuit detects either of an input voltage of the lighting circuit and an input voltage of the smoothing circuit, and sends a control signal to the dimming signal circuit, wherein the control signal is a signal for correcting a lighting time so that a light output of the light source can become a desired value.
