Abstract

The utility model discloses an integrated LED unit used on an operation shadowless lamp which consists of a shade, an LED unit and a power controller. The surface of the shade is on a same sphere with a radius between 100 to 140 mm. The LED unit adopts a reflector cup or a drawtube plus lens form. The LED unit is arranged on the shade and is communicated with the power. The power controller can realize DC/DC switch, is inputted as an AC or DC, is outputted as a DC and constant current, and is controlled by LED temperature. The utility model has the advantages of no strobe, uniform illumination, extremely long service life, safe use, adjusting brightness, environments protective green light source, energy saving and fast reaction speed, etc. The utility model can improve the operation quality and can guarantee the success of the operation.

Description

The integrated LED unit that is used for operation shadowless lamp

Technical field

Novel a kind of medicine equipment, the particularly a kind of integrated LED unit that is used for operation shadowless lamp of relating to of this use.

Background technology

Operation shadowless lamp is the conventional and indispensable equipment of hospital operating room, and using operation shadowless lamp is condition of work and prerequisite necessary in numerous operations.The indoor employed shadowless lamp light source of hospital surgical is to constitute lamp holder integral body by umbrella shape lamp housing and one group of based on halogen bulb at present.The shortcoming that it exists a lot of designs and uses,, center spot place brightness irregularities too high as temperature, power is big, aberration is big, color fidelity does not have specification requirement, should not be in the purification operating room use of high request etc., make the operation quality be affected.

Therefore, need a kind of operation lamp, advantages such as having and do not have stroboscopic, illumination is even, extra long life, safe in utilization, adjustable brightness, environment-friendly and green light source, energy savings, reaction speed are fast.

The utility model content

The utility model main purpose provides a kind of improved operation shadowless lamp light source, it, has and does not have stroboscopic as illuminator with LED, illumination evenly, advantage such as extra long life, safe in utilization, adjustable brightness, environment-friendly and green light source, energy savings, reaction speed be fast.

The integrated LED unit that is used for operation shadowless lamp of the present utility model is made up of lampshade, LED unit and power-supply controller of electric; The lampshade face of described lampshade is on 100-140 centimetre the same sphere at radius; The LED unit adopts reflector or lens barrel to add form of lens; Described LED unit is installed on the lampshade, and links to each other with power supply; Described power-supply controller of electric exchanges or direct current for realizing the DC/DC conversion and being input as, and is output as direct current, Constant Electric Current, is controlled by the LED temperature.

Further, can be at least one LED unit combination;

Further, described power-supply controller of electric can singlely be installed near the LED unit, also can make concentrated controller according to the LED element number;

Further, described lens numbers is at least one.

The beneficial effects of the utility model are: the integrated LED unit that is used for operation shadowless lamp of the present utility model, adopt LED as illuminator, there is not stroboscopic, because it is pure direct current supply that LED does not have the shadow cold light source, no stroboscopic, be difficult for making eyes to produce sense of fatigue, also can not produce humorous wave interference other equipment (as oscillograph) of working region; Illumination is even, and it is 180 degree uniform irradiations that LED does not have the shadow cold light source; Extra long life, the LED theoretical work life-span is 100,000 hours, and the theoretical life-span of operating lamp only is 1000 hours at present; Safe in utilization, what the traditional operation shadowless lamp used is based on halogen bulb, and based on halogen bulb is owing to the temperature height that produces, exist hidden danger safe in utilization with reasons such as explosions, and the integrated LED unit produces heat hardly, and be difficult for breaking, thoroughly eliminate above-mentioned hidden danger safe in utilization; Adjustable brightness, is furnished with special-purpose brightness controller (brightness controller has short circuit, overload, temperature protection function), the operator can be according to the adaptability regulated at will brightness of self brightness, makes it the comfort level that reaches ideal, makes that eyes are difficult for producing sense of fatigue when working long hours; 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 environmental protection, energy-conserving product.LED do not have the shadow cold light source because caloric value extremely low (not having radiation), do not influence observation thing quality; Energy savings, LED is a cold light source, and semiconductor lighting self does not pollute environment, compares with incandescent lamp, fluorescent lamp, and electric energy can reach more than 90%.Under same brightness, power consumption only is 1/10 of ordinary incandescent lamp, 1/2 of fluorescent tube.Power consumption little (low-voltage, low current start) average life span was greater than 45000 hours; Green light source, LED lamp DC driven does not have stroboscopic; Reaction speed is fast; Do not have infrared and composition ultraviolet, do not have radiation pollution, colour rendering is high and have very strong light emission direction, and 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 is for the visual fatigue that alleviates operative doctor in large-scale, the prolonged operations process, and it is particularly important to reduce unnecessary malpractice; Reaction speed is fast, and the LED response speed reaches nanosecond, the late effect that does not have conventional lights to have, and energising promptly reaches the brightest, and this is very useful in some special occasion; The operation shadowless lamp made from such light source just can improve the operation quality, makes the success of operation obtain better guarantee.

Description of drawings

Below in conjunction with accompanying drawing the utility model is described further.

Fig. 1 is an overall structure schematic diagram of the present utility model;

Fig. 2 is a LED cellular construction schematic diagram of the present utility model.

The specific embodiment

Fig. 1 is an overall structure schematic diagram of the present utility model, and Fig. 2 is a LED cellular construction schematic diagram of the present utility model, as shown in the figure, two LED unit, LED bulb 2 is installed on it is used as light source, utilize the mode of lens that visible light is gathered into light beam, and it is projected operative site; Two LED cell distribution are installed on the lampshade 1, link to each other with power supply by lampshade 1.And lampshade is to be resulting on 100-140 centimetre the sphere at radius, can be multiple shape, as hexagon, circle etc., also can be other shapes, and its main points are that the lampshade face must be on same sphere.Power-supply controller of electric can carry out direct current, constant current output to the LED bulb, the DC/DC conversion, and can realize the input of AC and DC power supply, the control of LED temperature; Power-supply controller of electric can singlely be installed, and also can make concentrated controller according to the LED element number certainly.

Present embodiment is to make those of ordinary skills understand the utility model; and to detailed description that the utility model carried out; but can expect; in the scope that does not break away from claim of the present utility model and contained, can also make other variation and modification, these variations and revising all in protection domain of the present utility model.
