Abstract

The embodiment of the invention discloses a lighting device comprising a lamp main shell with a containing cavity, a heat dissipation device, a light source and a front-end shell; one end of the lamp main shell is provided with a notch communicated with the containing cavity and a bayonet structure used for being connected with an optical accessory, and the position of the notch corresponds to the position of the bayonet structure; the heat dissipation device is arranged in the accommodating cavity; the light source is in heat conduction connection with the heat dissipation device and is positioned in the accommodating cavity or the notch; the front-end shell is provided with a through hollow cavity, one end of the front-end shell covers the light source, and the other end of the front-end shell penetrates through the notch towards the outer side of the notch; and light emitted by the light source penetrates through the hollow cavity of the front-end shell to be emitted outwards. In the lighting device, the light source can form an expected light emitting effect without protruding out of the lamp main shell, the light loss is effectively reduced, the space utilization rate is high, the heat conduction efficiency is high, and the overall performance and the use experience of the lighting device are improved.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a lighting device. Background technique [0002] In scenes such as videos, film and television dramas, and photography, it is often necessary to use additional lighting fixtures to fill or light the subject or scene. The lighting fixtures generally include a housing and a light source installed in the housing. The light source can be LED, etc., according to Different scenes have different requirements on the performance of lamps. In some scenes, it is often required that the output power of lamps should be large enough to output light with greater intensity, and light output with multiple colors and color temperatures. At the same time, it must also meet the requirements of illumination and uniformity. However, high power means that the heat generated by the light source will also increase, and the requirements for multiple colors, multiple color temperatures, illuminance and un...
