Abstract

The invention discloses a shadowless lamp, which comprises a light source frame, a plurality of light source assemblies fixedly arranged on the light source frame, a lens frame, a plurality of lens assemblies fixedly arranged on the lens frame, and a lifting mechanism, wherein the lens frame is arranged below the light source frame; the lens assemblies correspond to the light source assemblies one by one; each lens assembly is respectively in eccentric arrangement with the light source assembly corresponding to the lens assembly; the lifting mechanism is respectively connected with the lens frame and the light source frame; the lifting mechanism is used for enabling the lens frame and the light source frame to generate vertical relative displacement. When the shadowless lamp disclosed by the invention is applied, the operation amplitude of regulating the size of a shadowless lamp light spot is reduced, regulation is simplified, and the size of the light spot can be precisely controlled.

Description

technical field [0001] The invention relates to a shadowless lamp. Background technique [0002] At present, the adjustment method of most shadowless lamps in China adopts the dimming method of traditional hole lamps. The light sources are divided into several groups, and each group has several to a dozen LED light sources. Each group of light sources is evenly distributed around the center, and each light source has a fixed lens. for example figure 1 The state of the shadowless light, before dimming, the light spot is like figure 2 circle shown. When dimming, use the handle to make the LED component rotate around the hinge to form a image 3 The state of the shadowless lamp in the middle, or by adjusting the height of the lamp stand as a whole, these two methods are easy to make the spot become like Figure 4 The petal shape in the center greatly reduces the uniformity of the spot. For the shadowless lamp whose application publication number is CN102116436A, the lig...
