Problems solved by technology

However, in practical applications, the surgical shadowless lamp using halogen bulbs as the light source has the following disadvantages: high power consumption and low luminous efficiency, 20lm / w; high light source temperature, and difficult control of temperature rise at the spot in the surgical field; low color temperature, about 3500K , it must undergo complex optical processing to meet the requirements of surgical lighting; the life of the bulb is short, with an average life of about 500 hours, and the maintenance cost during use is relatively high
The development time of LED is relatively short. Since LEDs are used in surgical lights, many application technical problems such as optical path structure, heat dissipation, color temperature control, and spotlight adjustment of LED lamps must be solved. Therefore, there are not many commercial LED surgical lights on the market.

Abstract

The invention provides an operating shadowless lamp, comprising at least a cover body, a lens, a plurality of light source components which are arranged between the cover body and the lens, and a bearing frame which is used for arranging the power components, wherein, the light source component is provided with a plurality of LED light sources and a plurality of convergence lenses which correspondingly cover the LED light sources; furthermore, the light beam emitted by the LED light source is directly projected to the operating position by the lens and a softening mirror; the bearing frame is provided with an exes part; a plurality of light source components are arranged in the bearing frame by surrounding the axes part; compared with the prior art, as the operating shadowless lamp adopts the LED light source, the operating shadowless lamp has the advantages of no frequency flashing, uniform luminance, ultra-long service life, safe usage, adjustable brightness, environmental protection and green energy resource, quick response speed and the like; furthermore, the operating shadowless lamp can avoid the reflector (reflector bowl), thus effectively controlling the thickness of the lamp body and reducing the production cost.

Description

technical field [0001] The invention relates to a shadowless lighting device, in particular to an operation shadowless lamp with multiple LED light sources. technical background [0002] With the advancement of science and technology and the improvement of medical conditions, surgical shadowless lamps are indispensable as lighting equipment in the process of doctors performing operations on patients, whether in the operating room of the urban central hospital or in the surgical vehicle of the field hospital. Shadowless lamps are widely used. [0003] Many current large-scale surgical shadowless lamps are equipped with a halogen bulb as a single light source at the axis of the lamp cavity. The light emitted from the halogen bulb is refracted to the surgical site through the multi-faceted reflector (reflector bowl) arranged around the lamp head. In order to achieve shadowless lighting effect. However, in practical applications, the surgical shadowless lamp using halogen bulb...
