Embodiment Construction

[0025] see figure 1 , The shadowless lighting lamp of the present invention includes a housing 1 , a lamp board 2 , a condenser lens module 3 , a light-transmitting board 4 , a transparent board 5 and a focusing mechanism 6 .

[0026] The casing 1 is a cylindrical structural member, and its upper and lower openings are respectively provided with steps for installing the light board and the light-transmitting board.

[0027] The lamp board 2 is fixedly connected to the upper end of the housing, including an aluminum substrate 21 and a plurality (about one hundred) of high-power light-emitting diodes 22, and a plurality of high-power light-emitting diodes are evenly spaced on the aluminum substrate to form a shadowless lighting lamp light source.

[0028] Cooperate see figure 2 The condensing lens module 3 in the present invention is movably arranged in the middle of the housing 1 and can move up and down, including a mounting plate 31 and a plurality of Fresnel lenses 32, an...

Abstract

The invention provides a shadowless illumination lamp. The lamp comprises a shell, a lamp panel, a condenser lens module, a euphotic plate, a transparent plate and a focusing mechanism. A parallel offset is formed between the optical axis of each Fresnel lens on the condenser lens module and the optical axis of a corresponding high-power light emitting diode (LED) on the lamp panel, and the focusing mechanism can drive the condenser lens module to move up and down to adjust the size of light spots. Because the Fresnel lens is adopted, more rays emitted by the high-power LED can be converged, and the illumination of the light spots can be improved; because a method for performing parallel trace offset on the optical axis of the high-power LED and the optical axis of the lens to converge the light spots is adopted, the manufacturing cost of the traditional condenser system is greatly reduced; and because a lens module moving mode is adopted for focusing, the size of the light spots can be adjusted under the shadowless condition of projection light.

Description

technical field [0001] The invention relates to a medical lamp, in particular to a shadowless illuminating lamp. Background technique [0002] High-power and ultra-high-brightness light-emitting diodes have the characteristics of long working life, low energy consumption, and environmentally friendly devices. In recent years, with the development of semiconductor technology, high-power and ultra-high brightness light-emitting diodes have entered commercial production. As a new type of light-emitting element, high-power ultra-high-brightness light-emitting diodes are being widely used, and will gradually replace traditional light sources in the near future. [0003] Traditional light source shadowless lighting generally consists of traditional bulbs and concentrators. The traditional light bulb is placed at the focus of the concentrator, and the light emitted by the traditional light bulb is collected by the concentrator and projected to the lighting place to form a focused...
