Technical Field

The application relates to the field of light filling lamps, in particular to a lamp holder of a light filling lamp.

Background

The light supplement lamps are generally three, one is a photography light supplement lamp (also called a photography lamp or a camera light supplement lamp), a shooting greenhouse light supplement lamp (also called a plant light supplement lamp), and a license plate light supplement lamp (also called a white light). The camera light supplement lamp generally comprises a lamp cap, a soft light cover, a battery, a charger, an adapter rod and other accessories, and is used for supplementing light rays for camera shooting, photography, live broadcast and the like, so that higher-quality picture materials are obtained.

The conventional soft light cover light supplement lamp is divided into a lamp cap part and a soft light cover part which are arranged in a split mode, and when the light supplement lamp needs to be used, the soft light cover is installed on the lamp cap.

For example, the patent of the Chinese utility model with the publication number of CN209044267U discloses a lantern soft light box, which comprises soft light cloth and a supporting frame; the soft light cloth is wrapped outside the supporting frame; the supporting frame comprises two annular bases with different calibers, a bayonet ring and a plurality of supporting rods; two ends of each supporting rod are respectively and rotatably connected to the outer edges of two opposite end surfaces of the two annular bases; a clamping component is fixedly arranged on one side of the mounting support rod of the small-caliber annular base; a clamping frame is arranged on one surface, facing the small-caliber annular base, of the other large-caliber annular base; the clamping frame is clamped on the clamping component; the bayonet ring is detachably connected to the large-caliber annular base; the soft light cloth is in a lantern shape; the soft cloth is provided with a tearing opening; the tearing opening is provided with a magic tape.

To the correlation technique among the above-mentioned, the inventor thinks, must set up corresponding structure on the lamp holder in order to with the buckle ring adaptation on the diffuser, and at the in-process of in-service use light filling lamp, no matter use in the film studio or use in occasions such as direct broadcasting room, the consumer is with the diffuser installation completion back, carry out the arrangement of light filling lamp with the light filling lamp according to the light distribution design, accomplish the back of arranging of light filling lamp according to the light distribution design, the consumer generally can not remove the position of light filling lamp, just can not change the diffuser on the light filling lamp naturally yet, and the connection characteristic of buckle ring has decided, along with the extension of live time, the connected mode of buckle ring takes place to become flexible easily.
