A security light has a casing 103 for supporting an array of light emitting diodes, thereby presenting a light emitting surface and aiding removal of heat from them. A transparent cover 106 is attached to the casing to protect the light emitting diodes. The lens cover includes a plurality of lenses 107 moulded therein. Each lens is designed to focus light from a particular location within the array. The divergence of each individual lens is designed to enhance the uniformity of light from the apparatus. |
