Abstract

The invention discloses an LED photography lamp with the light emitting angle capable of being adjusted in multiple gears, and belongs to the technical field of photography lamps. The LED photography lamp comprises a horn-shaped fixing cylinder, a light reflecting layer is arranged on the inner side wall of the fixing cylinder, a detachable connecting cylinder a is installed at one end of the fixing cylinder, and the connecting cylinder a is connected with a photography lamp body through a clamping mechanism; a circular glass plate is fixedly arranged on the inner side wall of the end, away from the connecting cylinder a, of the fixing cylinder, rubber rings are fixedly connected to the outer side walls of the two sides of the glass plate, transparent rubber films are arranged on the sides, away from the glass plate, of the rubber rings in a sealed mode, and a micro air pump a and a micro air pump b are fixedly arranged on the outer side wall of the fixing cylinder. According to the invention, the transparent rubber films installed on the fixing cylinder are inflated or deflated, so that the two transparent rubber films are matched to form a convex lens, and therefore the light emitting angle of the LED photography lamp can be changed, and the light emitting angle can be freely adjusted according to the inflation degree of the transparent rubber films.

Description

technical field

[0001] The present invention relates to the technical field of photographic lamps, and more specifically relates to an LED photographic lamp whose light output angle can be adjusted in multiple steps. Background technique

[0002] In recent years, with the development of micro-movies, LED photography lights have generally entered the field of photography, and their applications are becoming more and more extensive. Photographic lights, also known as machine head lights, interview lights, and news lights, function on digital cameras like flashlights on digital cameras. If you want to shoot objects with dark surfaces, you must use these auxiliary light sources, otherwise it will affect the clarity of the picture, and it is impossible to improve it by post-processing. The function of photography lights on digital cameras is like flashlights on digital cameras. If you want to shoot dark objects, you must use these auxiliary light sources, otherwise the noise wil...
