Description
Technical field
The present invention relates to a kind of medicine equipment, particularly a kind of integrated high power LED illuminator that is used for medical illumination, optimum uses in operation illumination and the medical integral illumination in operating room, inspection chamber etc.
Background technology
Operation shadowless lamp, inspecting lamp, the interior integral illumination system of operating room etc. are the conventional and indispensable equipment of hospital, and using medical lighting system is condition of work and prerequisite necessary in numerous curative activities.The indoor employed shadowless lamp of hospital surgical, inspecting lamp etc. are by umbrella shape lamp housing and one group of huge lamp holder that based on halogen bulb constitutes at present.The problem that it exists a lot of designs and uses, as colour temperature can't regulate, temperature rise is too high, center spot place brightness irregularities, power consumption big, aberration is big, volume is big, the requirement that can not reach the vertical-horizontal lamina air flow, should not use at the purification operating room of high request, lighting quality is low influence the doctor to the tissue discriminating.
Summary of the invention
A kind of color temperature adjustable integrated high power LED medical lighting system, can be used for operation illumination, inspection illumination, the interior integral illumination of operating room in the medical treatment, it has color temperature adjustable integrated high power LED chip, optics, radiator, shell, LED driving governor, colour temperature brightness regulator, power supply changeover device, stube cable.The color temperature adjustable integrated high power LED chip is fixed on the radiator, radiator is fixedlyed connected with shell, optics is installed on the shell, stube cable one end connects the color temperature adjustable integrated high power LED chip other end and is connected with the LED driving governor, colour temperature brightness regulator and power supply changeover device are connected on the LED driving governor. and the optics that is equipped with previously at the color temperature adjustable integrated high power LED chip can be parabolic reflector and the combination of diffuse reflection light transmission piece, utilize the colour mixture of diffuse reflection light transmission piece to obtain the uniform light of color, optics also can make up for set of lenses, utilize the colour mixture of set of lenses to obtain the uniform light of color, and the light that the color temperature adjustable integrated high power LED chip sends is converged on the working face; The control signal that the colour temperature brightness regulator utilizes microprocessor to produce is controlled the dutycycle of each road output current of LED driving governor, thereby regulate the brightness colour mixture ratio of different colours tube core in the color temperature adjustable integrated high power LED chip, carry out brightness regulation and colour temperature in 3500K～6500K range regulation; Power supply changeover device can realize that converting the alternating current 220V power supply to low-voltage direct gives the power supply of LED driving governor.
The present invention can make different tissues observe clearly owing to adopt said structure can regulate the colour temperature and the brightness of output light within the specific limits continuously, and raising medical illumination quality reaches optimum and reduces because the malpractice that the wrong identification tissue brings.
The present invention compares the characteristics that have with traditional lighting source:
1, colour temperature can be regulated continuously, can make colour temperature adjustable continuously in 3500K～6500K scope by LED modules with different colors brightness ratio on the control chip, can regulate according to the definition difference of different tissues under different-colour to reach better illuminating effect;
2, adjustable brightness, by regulating the brightness of white light LEDs on the chip, the brightness of continuous adjusting output light makes it the comfort level that reaches ideal, makes that eyes are difficult for producing sense of fatigue when working long hours;
3, volume is little, has reduced the volume of illuminator greatly, and the influence that the air in medical illumination space flows reduces, and effectively raises the operating room depuration quality.
4, extra long life, the LED theoretical work life-span is 100,000 hours, and the life-span of Halogen lamp LED only is 1000 hours at present;
5, safe in utilization, what the traditional medical illumination was used is based on halogen bulb, and based on halogen bulb is owing to the temperature height that produces, easily reason such as explosion exists hidden danger safe in utilization, and LED temperature under better heat radiation situation is low and be difficult for breaking, and thoroughly eliminates above-mentioned hidden danger safe in utilization;
6, environmental protection, the LED lamp is shatter-proof, shock-resistant be difficult for broken, discarded object is recyclable, does not have mercury pollution, is real environment-friendly products;
7, green light source, reaction speed is fast; Do not have infrared and composition ultraviolet, do not have radiation pollution, have very strong light emission direction, hot spot is even; Dimming behavior is good, and colour temperature can not produce the collimation error when changing; The cold light source caloric value is low, can safe touch; These all are that incandescent lamp and fluorescent lamp are inaccessible.It can provide the illumination space of comfortable, can satisfy people's physiological health demand again well, and this organizes resolution ratio and reduce unnecessary malpractice particularly important for the visual fatigue that alleviates the doctor in large-scale, the long-time curative activity process, raising;
So just can improve lighting quality, make the minimizing malpractice that better guarantee arranged.
