Abstract
The utility model provides a shadowless illuminating lamp with a luminance compensation mechanism, which comprises a base, a plurality of groups of luminescent lamp panels arranged on the base and a luminance compensation mechanism, wherein the luminance compensation mechanism comprises a photoelectric controller and a plurality of photoelectric sensors; the photoelectric controller is externally connected with a power supply and is respectively connected with the luminescent lamp panels; and the photoelectric sensors are arranged at different parts of the base and are respectively connected with an electrical signal of the photoelectric controller. When an object enters a ray casting area of an LED, the photoelectric sensors sense the position of the object entering the lighting area, generate a shading signal and output to the photoelectric controller; and the photoelectric controller weakens the luminous intensity of the shaded luminescent lamp panel through control programs and increases the luminous intensity of the other luminescent lamp panels, so as to compensate the reduced light yield of the shaded luminescent lamp panel, maintain the total light yield and effectively reduce the shadow.
Description
Technical field
The utility model relates to a kind of medical light fixture, relates 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.
The utility model content
The purpose of this utility model 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 utility model 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 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.
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 the utility model band luminance compensation 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.
