Embodiment 1

[0030] Such as Figure 1~4 As shown, this embodiment provides an auxiliary supplementary light device suitable for the lower jaw, which includes a housing 1 and a drive circuit. The housing 1 is provided with a supplementary light mounting plate 3, and the supplementary light mounting plate 3 is The array is provided with LED lamp beads 4, and multiple LED lamp beads 4 are electrically connected to the drive circuit; the drive circuit adopts an independent digital dimming drive circuit, and a manual brightness adjustment is also provided on the housing 1 Knob 5, the knob 5 is electrically connected to the drive circuit; the front end of the housing 1 is also fixed with a transparent protective cover 6 opposite to the LED lamp bead 4, the housing 1 and the transparent protective cover 6 is also provided with a sealing layer 7, the sealing layer 7 is a sealing ring, and a color temperature sheet 8 is also provided in the transparent protective cover 6; a plurality of heat dissip...

Embodiment 2

[0035] Such as Figure 5As shown, the preferred embodiment of the present invention is to provide an auxiliary light supplement device suitable for the lower jaw. The structure and working principle of this embodiment are similar to those of Embodiment 1. For example, a dust-proof plate 11 is detachably and movably connected to the shell 1 , and the panel of the dust-proof plate 11 can fully cover the transparent protective cover 6 . A dust-proof plate 11 is provided to avoid the accumulation of dust and reduce the light transmission capacity of the transparent protective cover 6. The dust-proof plate 11 is disassembled when the auxiliary light-filling device is in use. When not in use, the dust-proof plate is covered, and the detachable parts are connected by snap-fit ​​or threaded connections.

[0036] Further, the anti-scratch layer 12 is also provided on the side of the dust-proof plate 11 opposite to the transparent protective cover 6, and the anti-scratch layer 12 avoid...

Embodiment 3

[0038] Such as Figure 6 As shown, the preferred embodiment of the present invention is to provide an auxiliary lighting device suitable for the lower jaw. The structure and working principle of this embodiment are similar to those of Embodiment 1 or 2, but the difference from Embodiment 1 or 2 is That is, the back of the housing 1 in this embodiment is pivotally provided with a length-adjustable bracket 2 , and the adjustment structure of the bracket 2 is a self-locking thread. A length-adjustable bracket 2 is added, and the bracket 2 is used to adjust the inclination angle of the housing 1, that is, to adjust the angle of fill light of the auxiliary fill light device. The self-locking structure prevents the adjusted position from loosening and affecting the The effect of auxiliary fill light.

Abstract

Disclosed is an auxiliary light supplement device suitable for a lower jaw. The auxiliary light supplement device suitable for the lower jaw comprises a shell and a driving circuit. A light supplementlamp mounting plate is arranged in the shell, and LED lamp beads are arranged on the light supplement lamp mounting plate in an array mode and electrically connected to the driving circuit. An independent digital light adjusting driving circuit is adopted by the driving circuit, a manual brightness adjusting knob is further arranged on the shell, and the knob is electrically connected to the driving circuit. A transparent protective cover which faces the LED lamp beads is fixedly arranged at the front end of the shell, and a color temperature sheet is further arranged in the transparent protective cover. The color temperature sheet is a color temperature color filter standard in configuration, and comprises various color temperatures. The number of the LED lamp beads is 240, and the current which flows through the LED lamp beads is constant. The power supply modes of the auxiliary light supplement device include a battery direct supply mode or a various-power-interface mode or an adaptive power source input mode. By the adoption of a lamp for the lower jaw of an announcer, the light on the face of the announcer is enhanced, and the defect that light supplement of a light supplement lamp is nonuniform or is not thorough is overcome.

Description

technical field [0001] The invention relates to the field of lighting equipment, in particular to an auxiliary supplementary light device suitable for the lower jaw. Background technique [0002] In news broadcasting, in many cases, the light distribution in the surrounding environment is not very uniform, and supplementary light is required. Therefore, a large number of LED supplementary lights have appeared on the market now. The main function of the supplementary light is to supplement the light in a certain direction in some occasions, and its purpose is to ensure that the direction it illuminates is well lit, which is convenient for cameras and cameras. [0003] Generally speaking, the fill light is a fixed connection, and the adjustable inclination angle is relatively limited, so that the shooting or photography at some angles cannot be supplemented by a better light source, and the shooting effect will also be affected. When the LED camera needs to be used for a long ...
