Description

A kind of energy-conservation shadowless lamp of touch

Technical field

This utility model relates to field of illumination lamp technology, is specifically related to a kind of shadowless lamp for operating room.

Background technology

Shadowless lamp is indispensable visual plant in surgical operation, it is desirable to surgical staff can be allowed to be clearly observed in operative incision and body cavity the object of different size, contrast, the degree of depth. Therefore, shadowless lamp needs to accomplish uniform illumination, and light quality is good, is beneficial to doctor and distinguishes tissue and internal organs etc. Additionally, shadowless lamp is also wanted to work long hours, and too much heat should not being distributed, in order to avoid affecting surgical environments, reducing surgical quality.

Traditional operation shadowless lamp is generally adopted Halogen light or ring type energy saving lamp, and in recent years, along with the development of LED illumination technology, the especially development of high-brightness white-light LED, LED shadowless lamp becomes the application trend in lighting for medical use field. But, existing New LED operation shadowless lamp is substantially made up of multiple lighting modules, and each lighting module comprises multiple LED array point source, employing integrally adjusting light tries, and for mostly being hand-operating light, light modulation speed is slow, lacking motility, troublesome poeration, automaticity and illumination utilization rate are low.

Utility model content

This utility model is for the defect of prior art, it is provided that a kind of simple in construction, the energy-conservation shadowless lamp of touch that reasonable in design, Dimming operation is flexible, automaticity is high.

For solving above-mentioned technical problem, this utility model adopts the following technical scheme that a kind of energy-conservation shadowless lamp of touch, including illuminator and power module, power module connects illuminator, illuminator includes light source and top board, light source is installed in top board, it is characterised in that: this shadowless lamp includes the host computer as operating mechanism and the slave computer as driving mechanism, and host computer connects slave computer; Host computer has processor and operating mechanism; Light source connects slave computer, and slave computer connects power module, and slave computer has microprocessor; Light source adopts LED lamp module, and LED lamp module includes LED array, and LED array is the LED lamp bead being covered with in top board, and LED lamp bead presses array discharge on top board.

Further, the processor of host computer adopts the S5PV210 processor of ARMCortex-A8; The microprocessor of slave computer adopts STM32 processor; Each LEDs lamp bead in LED array has only numbering and is independently connected with host computer. Slave computer adopts STM32 processor, the information with host computer of being responsible for is mutual and produces satisfactory pwm pulse signal, realize the brightness regulation to LED lamp module, namely to needing to increase the PWM ripple of the LED lamp bead output high duty ratio of brightness, the PWM ripple that the LED lamp bead output duty cycle needing to weaken brightness is relatively low, reaches to increase or weaken the purpose of brightness.

Further, TTL serial communication is adopted to be connected between host computer with slave computer.

Further, the operating mechanism of host computer includes touch screen, operating system and man machine interface; Host computer is also associated with image capture module. Touch screen adopts single-page design, easy and simple to handle, user clicks image and can complete to select the required LED region that regulates, and click increases, minimizing brightness button can send brightness regulation instruction to slave computer, clicks preservation/stop button and can start/stop to preserve operation video frequency.

Further, described image capture module adopts CCD camera, and CCD camera is installed on the central authorities of top board, is positioned at the center of LED array, for the collection to operation area image.

LED lamp bead presses array discharge on top board, and each LED lamp bead has corresponding numbering in systems, and the LED lamp bead output pwm signal of corresponding numbering is controlled its brightness by system as required; The slave computer instruction according to host computer, produce corresponding pwm signal control and regulation host computer and specify the LED brightness of numbering, by increasing the intensity of illumination of field of operation part, relatively weaken the intensity of illumination of non-surgical, while regulating surgical light regional luminance, improve illuminance utilization rate.

This utility model is by adopting camera to adopt and showing operative region scene with touch screen, and shadowless lamp operator's visual dead angle is less; Control single LEDs lamp bead brightness by man-machine interaction mode and realize the adjustment to shadowless lamp overall brightness, operate relative ease; Dimming process only increases operative region illuminance, relatively weakens non-surgical illuminance, improves Astral lamp light illumination utilization rate, has saved electric energy.
