Mobile LED operating shadowless lamp

Abstract

The invention discloses a mobile LED operating shadowless lamp with an adjustable switch disposed on a traversing carriage, and an optical collector secured on an arm extended transversely on the traversing carriage, where the optical collector consists of a focuser with a handle and a lamp panel with a bottom as a spherical surface concave downwards and plural radiating seats equipped with batteries of lens distributed thereon, where at least three lamp panels are distributed with equal interval around the focuser, to be hinged with the same through a hinge; an LED drive controller is secured on the radiating seat, a power converter and a standby power are connected with the input end of a power switcher, while the output end of the power switcher is connected with the LED driver controller and the adjustable switch connected with the LED drive controller in parallel; the LED drive controller are connected with plural high-power LED chips in parallel electrically. The invention is advanced with adjustable brightness, super long service life, safe utilization, and uniform luminous spot, which can improve illumination quality and reduce medical negligence.

Description

technical field [0001] The invention relates to a medical device, in particular to a mobile LED surgical shadowless lamp suitable for medical lighting used in operating rooms and examination rooms. Background technique [0002] Surgical shadowless lamps, examination lights, etc. are routine and necessary equipment in hospitals, and the use of medical lighting is a necessary working condition and prerequisite for many medical work. [0003] Most of the currently commonly used shadowless lamps are halogen lamps with a single light source. The light emitted by this halogen bulb is refracted to the surgical site through the multi-faceted reflectors arranged around the lamp head to achieve a shadowless lighting effect. In practical application, this kind of shadowless lamp has the following disadvantages: large volume, high power consumption, low luminous rate, high light source temperature, difficult to control the temperature rise of the surgical field spot, large color differe...

AI Technical Summary

Problems solved by technology

In practical application, this kind of shadowless lamp has the following disadvantages: large volume, high power consumption, low luminous rate, high light source temperature, difficult to control the temperature rise of the surgical field spot, large color difference, and cannot meet the requirements of vertical and horizontal air laminar flow. It is used in a clean operating room with high requirements, and low lighting quality affects doctors' identification of tissues

At the same time, this shadowless lamp also has disadvantages such as low color temperature, short bulb life, and high maintenance costs during use.

[0004] There are also surgical shadowless lamps that use multiple light sources. The multiple light sources of this shadowless lamp are set independently, and each light source still needs a reflector. In practical applications, the manufacturing process is complicated, the production cost is high, and its structure is not convenient for installing cameras. , road shadows and other defects that affect the image

[0005] As the light source of shadowless lamp, LED has obvious advantages. LED light source has the advantages of less power consumption, high luminous efficiency, low light source temperature, easy control of temperature at surgical field spot, easy adjustment of color temperature, close to natural light, and long bulb life. However, Since LED is used as the light source of shadowless lamps, it is difficult to solve the problems of heat dissipation, spotlight adjustment, and color temperature control.

[0006] The invention patent with the application number 200810201380.x, although it has the advantages of long life, safe use, adjustable brightness, low temperature rise, effective control of the thickness of the lamp body, and easy installation of the camera, etc., but because of its large size and complex structure, the cost Higher, there are problems such as failure to meet the requirements of vertical and horizontal air laminar flow, color temperature cannot be adjusted, and brightness at the center spot is uneven
