Abstract
The utility model relates to a minisize cold light source for medical use, which can work for a long time when driven by batteries. A focusing lens, a luminous source and power supply interfaces are connected in sequence in an insulating casing, wherein, the luminous source is composed of at least one white light emitting diode which is arranged on a concave light-reflecting umbrella, and the light beams of the luminous source are projected on a group of convex lenses with adjustable focal length, so that the light beams can be maximum; u focused on a light guide cone of an endoscope. Additionally, the power supply interfaces can be directly installed on batteries, or connected with AC-to-DC source and acquire electric energy from the USB interfaces of a computer. Since the white light emitting diode has small volume, low energy consumption, low light emission heat and high brightness, the utility model can work under portable power supplies as batteries, and has the advantages of small volume and convenient carryover.
Description
Affiliated technical field
The utility model relates to a kind of micro medical cold light source, especially can be at the battery-operated micro medical cold light source that works long hours down.
Background technology
At present, known Medical Cold Light Source structure is made up of light emitting source such as Halogen lamp LED, xenon lamp and interlock circuit.Its light-source brightness is strong, and is inconvenient but volume, weight move greatly, needs stable AC power, need could use on endoscope, head lamp, deep searchlight by optical fibers.General Medical Cold Light Source can't be operated under situations such as outage suddenly, and moving jolts damages easily, and be unfavorable for the going out first aid and the consultation of doctors are used.
Summary of the invention
Move inconvenient greatly in order to overcome existing Medical Cold Light Source volume, weight, the deficiency that can't operate under the situations such as outage, the utility model provides a kind of micro medical cold light source, this micro medical cold light source can not only play the cold light source illumination work under AC power, and can obtain electric energy by the USB interface of battery and connection notebook or common computer, do not need optical fibers and endoscope connection or lighting sources such as the Light on head for surgery connection or the head lamp of directly performing an operation; And volume is little easy to carry.
The technical scheme that its technical problem that solves the utility model adopts is: in insulation crust, focusing lens, light emitting source, power interface are linked in sequence, light emitting source is made up of 1-n white light emitting diode, be arranged on the concave surface Reflection umbrella, its light beam is projected on one group of convex lens of adjustable focal length, and light beam is focused on the endoscope leaded light awl to greatest extent; Power interface can directly be installed battery or connect the AC-DC power supply and obtain electric energy by computer USB interface.Because the white light emitting diode volume is little, consuming electric power is low, luminous heat is low, brightness is high, reach and can work under light power supply such as battery, and volume is little easy to carry.
The beneficial effects of the utility model are by the power supply of portable power supplies such as battery, need directly not use on endoscope, head lamp, deep searchlight by optical fibers easily in the cold light source illumination.
