Abstract
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.
