Abstract: The object of the present invention is to provide a light source (101) for a luminaire or lantern, the light source (101) comprising: at least one light emitting diode (LED), a mantle structure (112) with which the LED (101) is fast within the mantle structure (112), the mantle structure (112) being both transparent or at least translucent and arranged to intercept and re-distribute light from the LED and, an optical element (117) in the mantle structure (112) for biasing light from the LED (101) away from a direction in which illumination is unwanted or at least is wanted at reduced intensity. The optical element (117) is angularly adjustable such that the light emitted may be directed.

Abstract: A street light has a hollow standard having a lower end and an upper end. The standard is root mounted at its lower end and supports a lamp and a solar panel. An illumination circuit is mounted in the base compartment and connects a battery to the lamp for control of the lamp. A charging circuit connects the battery to the solar panel and to an electricity connection for charging. A control circuit inside the base compartment controls the brightness. The electricity connection extends from the root portion of the standard for connection of the light to an AC electricity supply. The charging circuit is programmed to connect the battery to the electricity supply at low electricity tariff times and to disconnect the battery from the mains before high electricity tariff times. The charging circuit is programmed to connect the battery to the solar panel for charging during daylight.
