Abstract
The utility model relates to a LED lamp used in an operation. The LED lamp is mainly characterized in that the LED lamp is formed by a controller, an operation panel, N LED driving modules and N LED lamp groups through connection; the controller is connected with the operation panel; the operation panel is provided with an operation button; the controller is connected with the N LED driving modules through N I/O interfaces respectively; an output terminal of the each LED driving module is connected with one LED lamp group. The design of the lamp of the utility model is reasonable. A surgical operation shadowless lamp LED lamp is formed by using a mode that the controller controls the LED lamp group. The LED lamp possesses the following characteristics that luminous efficiency is high; a calorific value is low; thermal radiation is low; a service life of a bulb is long; a failure rate is low; the light used in the operation is pure; performance is reliable; power consumption is low and so on. Operation needs of various kinds of operating rooms are satisfied.
Description
Technical field
The utility model relates to a kind of LED lamp, especially a kind of operation LED lamp.
Background technology
Operation shadowless lamp is the lighting that uses in operation.Have or not the characteristics such as shadow, cold light, high illumination, and the colour temperature of requirements of operation is arranged.Do not have in the field of illumination of namely performing the operation without shadow doctor's the shadow of head, hand and operating theater instruments, guaranteeing clearly to see organ, tissue and the blood vessel of operation inner chamber, and the situation of seeing the inner chamber deep clearly.The cold light operation shadowless lamp adopts independent catoptric system, water ripples to process the major-minor bulb of face glass and 100W/12V～300W/24V mostly at present, and the common disadvantage of existence is: luminous efficiency is low, caloric value is high, thermal radiation is strong, power consumption is large, bulb service life is short, failure rate is high, lack the power-failure protecting measure.There is the bibliographical information operation shadowless lamp to cause scalded patient's accident, even has bibliographical information to say that the operation shadowless lamp that uses at present is a key factor that causes operator's presbyopia.Therefore, existing medical operation shadowless lamp can not satisfy the needs of operating room far away.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of reasonable in design, failure rate is low, operation to use up a kind of operation LED lamp pure and that power consumption is low.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of operation LED lamp, connected and composed by controller, guidance panel, a N LED driver module and N LED lamp group, described controller is connected with guidance panel, described guidance panel is provided with operation push-button, described controller is connected with N LED driver module by N I/O interface respectively, and the output of each LED driver module is connected with a LED lamp group.
Further, described controller is the P89LPC932 singlechip chip, and described controller is controlled the LED driver module by the I/O interface in PWM pulse-width regulated mode.
Further, described LED driver module adopts the LM3402 driver module.
The beneficial effects of the utility model are:
(1) the utility model adopts LED lamp group to form desirable operation lighting source, has temperature rise little, the characteristics such as service time is long, the lighting source color developing effect is good, dispel the heat less, failure rate is lower, ruddiness and the high problem of ultraviolet light good fortune illumination of conventional light source have been solved, make operation use up purer, guaranteed that the doctor can clearly observe the object that is in incision different depth and contrast, satisfies the requirements of operation of various operating rooms.
(2) this operation shadowless lamp adopts controller that LED lamp group is controlled, and its control mode is flexible, and reliability is high, long service life, the illumination stable and uniform, definition is high, power consumption is low effective without shadow, is difficult for making eyes to produce sense of fatigue, can not produce humorous wave interference.Guarantee the reliability service of operation shadowless lamp, thereby avoided unnecessary operation error.
Description of drawings
Figure l is circuit block diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described:
As scheme as shown in l, a kind of operation LED lamp comprises controller, guidance panel, a N LED driver module and N LED lamp group.The communication interface of described controller is connected with guidance panel by the RS485 bus, described controller is connected with N LED driver module by N I/O interface respectively, the output of described each LED driver module is connected with a LED lamp group, described each LED lamp group is comprised of 9 white led lamps of series connection, and described LED driver module can provide the constant current drive current for LED lamp group.Described guidance panel is provided with operation push-button, realizes control operation to the LED lamp, adjustings such as brightness and control mode by operation push-button.The quantity N of described LED driver module and LED lamp group is 20, and therefore, the medical operation shadowless lamp is comprised of the white led lamps of 180 high brightness altogether.Described white led lamps forms certain shape and also is arranged on needed position, for example forms petal-shaped and is arranged on ceiling, metope or counter-jib suspension, can satisfy the demand of differing heights and angle in operation.In the present embodiment, controller adopts the P89LPC932 singlechip chip, the LED driver module adopts the LM3402 driver module, described each LED lamp group is connected to respectively on an I/O interface on controller, make each LED lamp group consist of the parallel operation mode, described each LED lamp group is separate, if the work that one group of LED lamp group is damaged does not affect other LED lamp groups is arranged, has guaranteed the normal operation of medical operation shadowless lamp.Controller to the control mode of LED driver module is: the I/O interface output pwm pulse of controller, control the LED driver module in PWM pulse-width regulated mode, and realize the step-less adjustment function, the electric current that flows through each LED lamp is about 120～320mA.
It is to be noted; the utility model is not limited to above-mentioned execution mode; any simple modification, Combination application, equivalent variations and modification that any those skilled in the art do above-described embodiment in based on technical solutions of the utility model all belong in protection range of the present utility model.
Claims (3)
