Abstract
The invention provides a shadowless lighting lamp with a brightness compensation mechanism. The shadowless lighting lamp comprises a base, a plurality of groups of luminous lamp plates and the brightness compensation mechanism, wherein the plurality of groups of luminous lamp plates are arranged on the base; the brightness compensation mechanism comprises a photoelectric controller and a plurality of photoelectric sensors; the photoelectric controller is externally connected with a power supply and connected with all luminous lamp plates respectively; the plurality of photoelectric sensors are arranged at different parts of the base and are respectively in electric signal connection with the photoelectric controller; when an object enters a projection ray area of a light-emitting diode, the photoelectric sensors sense the position of the object which enters an illumination area, generate light-shading signals and transmit the light-shading signals to the photoelectric controller; and the photoelectric controller reduces the luminous intensity of the light-shaded luminous lamp plate by a control program in the photoelectric controller, improves the luminous intensity of other luminous lamp plates, compensates the reduced luminous quantity of the light-shaded luminous lamp plate, maintains luminous total quantity and effectively reduces shadows.
Description
Technical field
The present invention relates to a kind of medical light fixture, relate in particular to a kind of shadowless lamp with luminance compensation mechanism.
Background technology
The light emitting diode of high-power super brightness has long working life, energy consumption is low, luminescent spectrum does not contain advantages such as infrared and ultraviolet, is a kind of clean environment firendly light source.This light source is admitted and is used by the shadowless lamp field.Traditional light source, shadowless lighting are throw light to be converged by optically focused by general bulb to produce no shadow hot spot.
Traditional bulb certainly leads to heat when luminous, and contains infrared and ultraviolet light at the light that sends, and can produce harmful effect to personnel.By traditional bulb and general light emitting diode constitute shadowless lamp when on projecting light path, running into object and blocking, can not reduce its hot spot brightness even there is shadow yet.
Summary of the invention
Purpose of the present invention exactly in order to address the above problem, provides a kind of shadowless lamp with luminance compensation mechanism.
In order to achieve the above object, the present invention has adopted following technical scheme: a kind of shadowless lamp with luminance compensation mechanism, comprise pedestal and the multi-group light-emitting lamp plate that is installed on the pedestal, the projected spot of multi-group light-emitting lamp plate forms on focussing plane has the overlapping hot spot that weakens shade;
Also comprise the luminance compensation mechanism that is installed on the pedestal, this luminance compensation mechanism comprises photoelectric controller and a plurality of photoelectric sensor, the photoelectric controller external power supply also links to each other respectively with each luminous lamp plate and can control the luminous intensity of each luminous lamp plate, a plurality of photoelectric sensors are installed in the different parts of pedestal and link to each other with the photoelectric controller signal of telecommunication respectively, the position generation shielding signals that the photoelectric sensor perception enters object in the light area transfers to photoelectric controller, photoelectric controller weakens generation by the luminous intensity of the luminous lamp plate of shading by control program wherein, increase the luminous intensity of other luminous lamp plate,, kept luminous total amount and reduce shade effectively by the luminous quantity that the luminous lamp plate of shading is reduced with compensation.
Described luminous lamp plate comprises aluminium base and a plurality of large-power light-emitting diodes that are mounted on the aluminium base, is respectively equipped with one group of twice optical lens that is used to produce the polymerization hot spot in the place ahead of each light emitting diode.
Be lined with the heat radiation aluminium block of the setting angle that is used to adjust luminous lamp plate between described each luminous lamp plate and the pedestal respectively.
Described luminous lamp plate is 8, is separately installed with a photoelectric sensor on the pedestal between per two luminous lamp plates, and each photoelectric sensor extend out to the below of luminous lamp plate respectively.
Described pedestal is the aluminum design assembly.
The shadowless lamp of band luminance compensation of the present invention mechanism makes it compared with prior art owing to adopted above technical scheme, have following advantage and and characteristics:
1, owing to is provided with luminance compensation mechanism, when object enters the throw light zone of light emitting diode, the position generation shielding signals that the photoelectric sensor perception enters object in the light area transfers to photoelectric controller, photoelectric controller weakens generation by the luminous intensity of the luminous lamp plate of shading by control program wherein, increase the luminous intensity of other luminous lamp plate,, kept luminous total amount and reduce shade effectively by the luminous quantity that the luminous lamp plate of shading is reduced with compensation.
2, because aluminium the substrate light emitting diode and the high-performance secondary optics assembly that mount, make the luminous intensity of lamp plate, manufacture craft, combination properties such as reliability improve a lot.
3, because lamp plate is installed on the aluminum structure, improved the radiating condition of semiconductor light emitting diode greatly, the service life of having improved luminescent diode.
