LED photographic lamp capable of changing illumination angle

Abstract

The invention provides an LED photographic lamp capable of changing an illumination angle. The LED photographic lamp comprises a lamp holder assembly and a control box assembly, wherein the lamp holder assembly is connected with the control box assembly; two notch sections are symmetrically arranged on both sides of the front end of the front light emitting surface of the lamp holder assembly; and each notch section comprises at least two notches. The LED photographic lamp also comprises an optical lens assembly, wherein the optical lens plates correspond to the notches; and both ends of the optical lens plates are respectively embedded in the two symmetrical notches. The lamp holder assembly is connected with the control box assembly in a detachable manner through a buckle mechanism. The LED photographic lamp can accurately, rapidly and conveniently change the illumination angle without influencing the light intensity and the light quality.

Description

【Technical field】 [0001] The invention relates to a light source device for photography and videography, in particular to an LED videography light. 【Background technique】 [0002] Most of the existing LED video lights cannot change the illumination angle. Although a very small number of LED video lights can change the illumination angle, they cannot obtain the required illumination angle accurately, quickly and conveniently without affecting the light quality. [0003] The existing LED video lights that can change the irradiation angle generally adopt the following two methods: 1. Use a four-leaf light baffle to limit the irradiation range of the video light to control the illumination angle of the video light. Its shortcoming is: it can only be roughly Changing the illumination angle will make the edge of the light not smooth or deformed; 2. Control the illumination angle of the whole lamp by mixing and adjusting two groups of illuminants with different illumination angles....

Its shortcoming is: it can only be roughly Changing the illumination angle will make the edge of the light not smooth or deformed; 2. Control the illumination angle of the whole lamp by mixing and adjusting two groups of illuminants with different illumination angles. The light can also affect the quality of the light, making the brightness of the center of the illumination inconsistent with the edge (the area illuminated by the two sets of lights together is particularly bright, while the brightness of the wider angle set of lights is inconsistent)
