摘要： There is provided a lighting apparatus and a method for reducing discomfort glare. The method comprises a step of providing a first portion of light radiation in a first incident angle range; and another step of providing a second portion of light radiation in a second incident angle range consecutive to the first incident angle range. The first incident angle range is greater than the second incident angle range viewed from a vertically downward direction of a light source emitting the light radiation, and the correlated color temperature of the first portion of light radiation is lower than that of the second portion of light radiation.

摘要： The invention discloses an outdoor luminaire. The outdoor luminaire comprises a light module comprising at least one LED unit; wherein said light module is configured such that the light emitted by the light module has a first luminous intensity value no less than 10 cd/klm at a first angle (γi), which is a vertical angle of 90 degrees above a direction pointing directly downward from the luminaire. In this way, the luminous intensity of the outdoor luminaire at a vertical angle of 90 degrees is guaranteed to be no less than 10 cd/klm Since the end user sees the light emitted at a vertical angle of 90 degrees no matter how far away he is from the outdoor luminaire, the end user always perceives a certain level of brightness. Such “certain level of brightness” is helpful in increasing the adaptation level of the end user, and can effectively reduce the end user's perception of glare.
