Abstract

An integrated large-power LED medical illumination chip can be used for medical operation illumination, medical examination illumination as well as integral illumination in an operation room as a color-temperature-adjustable light source. The integrated large-power LED medical illumination chip mainly comprises LED tube cores, a base plate, a heat dissipating plate, a power supply adapting wire and an LED driving controller. Different colors of LED tube cores are integrated on the base plate of a circuit board according to a certain array, and the base plate is connected to the heat dissipating plate. The LED tube cores in the integrated chip are separated into multiple groups according to colors and separately powered. The brightness of the LED tube cores with various colors can be independently regulated. Through regulating the color mixing ratio of different colors of LED tube core strings, the integrated large-power LED chip can be regulated to have any color temperature and brightness in a range of 3500K to 6500K. The integrated large-power LED medical illumination chip can be used for illumination in environments with special color temperature requirements, such as the operation room and an examination room, is particularly suitable for medical illumination and the like, and is favorable to improving medical illumination quality and reducing medical accidents.

Description

Color temperature adjustable integration high-power LED medical illumination chip

Technical field

The present invention relates to a kind of light source, particularly in medical illumination as the integration high-power LED medical illumination chip of adjustable color temperature that light source uses, optimum in operating room, inspection chamber etc. as operation, check in illumination and medical integral illumination and use as light source.

Background technology

Lighting source Deng Shi hospital routine and necessary equipment, use medical lighting system to be condition of work necessary in numerous curative activity and prerequisite.The shadowless lamp, inspecting lamp etc. that use in Hospitals at Present operating room form lamp holder entirety by umbrella shape lamp housing and one group of halogen bulb.It also exists the problem on some design and devdlop, as colour temperature cannot regulate, temperature rise is too high, center spot place brightness irregularities, power consumption are large, aberration is comparatively large, volume is large, the requirement that can not meet vertical-horizontal lamina air flow, should not in the purified operation room use etc. of high request, lighting quality is low affects doctor to tissue distinguishing.

Summary of the invention

The object of this invention is to provide a kind of color temperature adjustable integration high-power LED medical illumination chip, can surgical light in medical treatment, check in illumination, operating room and use as light source in integral illumination.

Color temperature adjustable integration high-power LED medical illumination chip of the present invention, comprise LED die, substrate, heat sink, power switching line, LED driving governor, the LED die close-packed array that can control two or more color of brightness is respectively integrated in be had on the substrate of circuit board, and substrate is fixed on heat sink.

The quantity of same color LED die is two or more, and the LED die of same color is cascaded, and to contact the different outputs be connected on LED driving governor as utilizing the LED modules with different colors tube core of power switching line.

LED driving governor controls the brightness of often kind of LED strip, the gentle brightness of the random colour that above-mentioned integrated high power LED chip can be regulated to have within the scope of 3500K ~ 6500K by the colour mixture ratio of LED modules with different colors tube core string.The present invention due to adopt said structure can regulate continuously within the specific limits integrated LED chip send colour temperature and the brightness of light, different tissues can be made to observe clearly, improve medical illumination quality and reach optimum and reduce the malpractice brought because of wrong identification tissue.

The present invention compares with traditional lighting source the feature had:

1, colour temperature can regulate continuously, can make colour temperature continuously adjustabe within the scope of 3500K ~ 6500K by LED modules with different colors brightness ratio on control chip, can carry out adjustment reach better illuminating effect according to the definition difference of different tissues under different-colour;

2, brightness is adjustable, and by regulating the brightness of white light LEDs on chip, the brightness of continuous print regulation output light, make it to reach ideal comfort level, when making to work long hours, eyes not easily produce sense of fatigue;

3, volume is little, and a lot of LED die are integrated on very little substrate by integrated LED chip closely, reduce the volume of illuminator greatly, and the impact of the air flowing in medical illumination space reduces, and effectively raises 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 is only 1000 hours at present;

5, use safety, traditional medical illumination uses halogen bulb, and halogen bulb also exists use safety hidden danger due to reasons such as high, the easy explosions of temperature that produces, and LED temperature under better heat dispersal situations is low and not easily break, and thoroughly eliminates above-mentioned use safety hidden danger;

6, environmental protection, LED is shatter-proof, shock-resistant not easily broken, discarded object is recyclable, not having mercury pollution, is real environment-friendly products;

7, green light source, reaction speed is fast; Do not have infrared and composition that is ultraviolet, do not have radiation pollution, have very strong light emission direction, hot spot is even; Dimming behavior is good, can not produce the collimation error during colour temperature change; Cold light source caloric value is low, can safe touch; These are all that incandescent lamp and fluorescent lamp do not reach.It can provide the illumination space of comfortable, can meet again the physiological health demand of people well, this for alleviate in large-scale, long-time curative activity process doctor visual fatigue, improve organize resolution ratio and reduce unnecessary malpractice particularly important;

So just lighting quality can be improved, minimizing malpractice is had better guarantee.

Fig. 2 is the LED die array structure schematic diagram of the embodiment of the present invention.

Detailed description of the invention

Fig. 1 provides 1 embodiment of the present invention, 81 LED die 1 are welded on to be had on the substrate 2 of circuit board, LED die 1 has red-light LED tube core R, green light LED tube core G, blue LED die B, white light LEDs tube core W4 kind, the LED die 1 of different colours by square formation array distribution on a substrate 2, the circuit board on substrate 2 is relied on same color LED die 1 to be cascaded, substrate 2 is fixedly mounted on radiator 3, power switching line 4 one end connects LED die string, another section of power switching line 4 is connected on LED driving governor 5, power switching line divides 4 tunnels to provide electric current for 4 kinds of color LED die strings, LED driving governor 5 is regulated to control the brightness ratio of shades of colour LED die 1, thus by the colour mixture of LED modules with different colors tube core 1, just can adjust light emission color temperature in the scope of 3500K ~ 6500K.
