specific Embodiment approach

[0033]The LED surgical shadowless lamp with multiple combined lenses is set in a centrally symmetrical structure, including a light source plate and a lamp holder, and is characterized in that the light source plate includes a preset number of side light source plates 7 and 1 The central light source block 5, the side light source block 7 and the central light source block 5 are fixedly arranged on the light frame at a preset angle, the light source block is composed of independent light emitting unit groups, and the independent light emitting unit groups are composed of LED lamps The LED lamp cup includes LED light-emitting chips and lenses, the central light source block 5 includes an independent light-emitting unit group V, and the side light source block 7 includes an independent light-emitting unit group I1, an independent light-emitting unit group II2, and an independent light-emitting unit group Unit group III3 and independent light-emitting unit group IV4, the side ligh...

Embodiment 1

[0048] When the light spots formed by the independent light-emitting unit group I1 and the independent light-emitting unit group II2 and the test surface 6 are 42%, the illumination is 100%, and the light spots formed by the independent light-emitting unit group III3 and the independent light-emitting unit group IV4 are 89%, and the illumination is 100%. Medical requirements need to concentrate the light to reduce the light spot. It is necessary to adjust the current of the independent light-emitting unit group I1 and the independent light-emitting unit group II2 so that the light spot formed by the independent light-emitting unit group I1 and the independent light-emitting unit group II2 and the test surface 6 is 60%, and the illuminance is 70. %; The light spots formed by the independent light-emitting unit group III3 and the independent light-emitting unit group IV4 are 56%, and the illuminance is 70%, which compensates for the reduction of the central illuminance of the spot...

Embodiment 2

[0050] When the light spot formed by the independent light-emitting unit group I1 and the independent light-emitting unit group II2 and the test surface 6 is 100%, the illumination is 25%, and the light spot formed by the independent light-emitting unit group III3 and the independent light-emitting unit group IV4 is 5%, and the illumination is 30%. Medical requirements need to enlarge the light spot, and it is necessary to adjust the current of the independent light-emitting unit group I1 and the independent light-emitting unit group II2, so that the light spot formed by the independent light-emitting unit group I1 and the independent light-emitting unit group II2 and the test surface 6 is 60%, and the illumination is 70%; The light spots formed by the independent light-emitting unit group III3 and the independent light-emitting unit group IV4 are 56%, and the illuminance is 70%, which compensates for the reduction of the central illuminance of the spot of the whole light, so th...

Abstract

The invention discloses an LED operation shadowless lamp provided with various composite lenses and an adjustment method. The LED operation shadowless lamp is of a centrosymmetrical structure and comprises a central lamp source module, lateral lamp source modules and a lamp rack. The LED operation shadowless lamp is characterized in that the central lamp source module and the lateral lamp source modules are arranged to be of independent illumination structures, each lamp source module is composed of a preset number of illumination sets, each illumination set is composed of illumination units, each illumination unit is composed of an LED illumination chip and the corresponding lens, and the lenses are of various structures. The LED operation shadowless lamp provided with the various composite lenses and the adjustment method have the beneficial effects that the lateral lamp source modules are provided with the different lenses and can be flexibly utilized to compensate for the center illuminance of the central lamp source module; and the independent illumination unit sets can drive adjustment current independently to adjust the illuminance of the lens illumination unit sets of different specifications of execution units, light spots of different sizes, center illuminance and color temperatures can be generated, and the shadowless effect is achieved through current adjustment of the illumination unit sets.

Description

technical field [0001] The invention belongs to the technical field of medical lighting equipment, and more specifically relates to an LED surgical shadowless lamp with multiple combined lenses and an adjustment method. Background technique [0002] LED surgical shadowless lamp is one of the indispensable equipment in the operating room. [0003] The field provides the lighting required for clinical practice; usually, surgical incisions are of different sizes or even irregular [0004] Therefore, the LED surgical shadowless lamp needs to adjust the light spot to meet the needs of different operations. [0005] field lighting requirements. [0006] At present, there are two main ways to realize the adjustment of the light spot of the LED surgical shadowless lamp, one is mechanical focusing, [0007] Adjust the angle of each light source in the same way as the mechanical method to realize the change of the light spot; the other is electronic focusing, mainly through [000...
