Abstract (en)
[origin: EP3462077A1] The present invention discloses a lighting device, including: a housing, an optical element connected with the housing, a receiving chamber formed by engaging the housing with the optical element, and a light source component and a driving power supply component both located in the receiving chamber. The lighting device further includes a passage located in the receiving chamber, the passage passes through the housing and the optical element, and an interior of the lighting device is communicated with an exterior of the lighting device by the passage. Heat generated by the light source component in the lighting device can be effectively and quickly dissipated through the above-mentioned passage, without the need of additionally disposing a heat dissipation component, thereby reducing the cost and the weight of the lighting device.
