Description

    Technical Field
  • The present invention relates to an illumination angle adjusting device and an illuminating device comprising the illumination angle adjusting device.
    • Background Art
  • The spot light is a common illuminating device and widely used in, for instance, exhibition instruments.
  • In recent years, with the wide applications of LED lamps, LED lamp light sources also start to be used in spot lights. The spot light usually needs to be rotated to change an illumination area. The traditional spot light has no problem in rotation, but an LED spot light has some problem in rotation. As a heat sink is needed for heat dissipation of the LED, the LED spot light will use aluminum alloy as the heat sink, then the LED spot light is heavier than the traditional spot light due to such heat sink. Therefore, an operator should rotate the whole heavy LED spot light when the rotating direction should be adjusted.
