Abstract: A lighting unit has an input connector which has a first terminal arrangement which connects to a protection circuit to engage a lighting driver in an initial connection of the lighting unit (14) and the lighting driver (12), and a second terminal arrangement which connects to a light source. The second terminal arrangement is adapted to engage the lighting driver later than an engagement of the first terminal arrangement to the light driver. The protection circuit (22) is adapted to operate earlier than an engagement of the light source (20) to the lighting driver (20). The protection circuit prevents current surges from being delivered by the lighting driver at the time of connection of the lighting unit. The protection circuit is only applied temporarily, before direct connection is made between the light source and the lighting driver.

Abstract: A method is disclosed of controlling a LED, comprising driving the LED with a DC current for a first time, interrupting the DC current for a second time such that the first time and the second time sum to a period, determining at least one characteristic of the LED while the DC current is interrupted, and controlling the DC current during a subsequent period in dependence on the at least one characteristic. The invention thus benefits from the simplicity of DC operation. By operating at the LED in a DC mode, rather than say in a PWM mode, the requirement to be able to adjust the duty cycle is avoided. By including interruptions to the DC current, it is possible to utilize the LED itself to act as a sensor in order to determine a characteristic of the LED. The need for additional sensors is thereby avoided.

Abstract: A method of controlling an electronic ballast for a lighting circuit, the ballast including a bleeder, for use with dimmer circuits, by, in response to a mains supply being connected to the lighting circuit, determining whether a dimmer circuit is present in the lighting circuit; and in response to determining a dimmer circuit is not present, disconnecting the bleeder from the lighting circuit at least until the mains supply is disconnected. The method may be used during start, and the determination of whether a dimmer circuit is present is stored at least until the mains supply is disconnected. Determination of either a leading or trailing edge phase cut dimmer may be made by looking for deviation from the expected sine-wave voltage, either directly through temporal or voltage deviation, or indirectly by examining the second differential of the voltage with respect to time.
