Description
Technical field
This utility model is related to medical instruments field, specifically a kind of portable medical headlight illumination system.
Background technology
In recent years, cardiothoracic surgery of the headlight for medical use of LED light source in hospital, cardiovascular surgery, neurosurgery, orthopaedics, ear
The section office such as Bi Hou sections, department of general surgery, the department of stomatology, ophthalmology, plastic surgery and department of dermatologry have and are widely applied.The head of LED light source
The formula headlight for medical use of wearing has high brightness, the characteristics of hot spot irradiation area is gaze area, or even is applied to local under operation shadowless lamp
Illumination is not enough and need the situation of light filling, but brightness, uniformity to its hot spot have higher requirement, generally speaking, one
Good headlight for medical use illuminator, it should with high brightness；Hot spot is uniform；Compact conformation, it is lightweight；Continuous lighting time is long；
Wear conveniently, the characteristics of reliable；
LED is a kind of light source of high dispersion angle, and especially high-power LED, the angle of divergence of its full width at half maximum typically exist
110o~150o；It is also simultaneously area source, at present the luminescence chip of high-power LED it is minimum also in 1mmX1mm or so；This two
Individual feature determines that utilization rate of its light in headlight for medical use is very low, on the one hand have impact on the brightness of head lamp, does not on the one hand have profit
