specific Embodiment approach

[0031]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

[0046] 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

[0048] 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 adjusting method of an LED (light-emitting diode) shadowless operating lamp with various combined lenses. The adjusting method is characterized in that the method is used for adjusting the LED shadowless operating lamp with the various combined lenses, the LED shadowless operating lamp with the various combined lenses comprises an LED emitting chip, and the LED emittingchip is set into a structure mode which changes color temperature by adjusting current. The adjusting method includes the steps: illumination adjusting; light spot adjusting; color temperature adjusting. The adjusting method has the advantages that light spots with different diameters, center Illuminations and color temperature formed by emitting unit lenses with different light cup sizes, hook faces and emitting angles are adjusted, current can be independently driven and adjusted, Illuminations of lens luminescence units with different specifications of an execution unit are adjusted, the light spots with different sizes and center brightness and color temperatures can be generated, the current of a luminous unit group is adjusted, and shadowless effects are achieved.

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. 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 range 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 [0008] By arranging a l...
