Description
Technical field
The present invention relates to the continuously adjustable LED spotlight of a kind of angle on a large scale.
Background technology
LED is because of its special packaged type; Make the lamp pearl this as fixing irradiating angle; Mostly be in the light fixture that the angle of fixing shines so be applied to, so working method is then very inconvenient in video display illumination and lighting, hopes that the LED lamp can resemble also that traditional spotlight is works; Have the continuous adjustable function of range of exposures and irradiating angle, this is the weakness of LED lamp just.The photography of angle adjustable at present appears on the market with the LED light fixture, and main implementation has two kinds: first kind is before LED lamp pearl, to install lens additional, changes irradiating angle through the distance of adjusting lens and lamp pearl, and the method and traditional spotlight working method are similar; Another kind is to realize angular adjustment through the angle angle of adjusting the relative lamp axes of circuit board (or aluminium base) that LED lamp pearl is installed.First kind of mode is not suitable for the lamp applications of more LED lamp pearl.The mode that also has utilization to change set of lenses changes irradiating angle, but inconvenient, can not realize the Continuous irradiation adjustable angle, second kind of lamp applications that is fit to a lot of LED lamp pearls.
The defective that the present invention is directed to second way angle adjustable narrow range is improved.The patented technology of the second way is existing good multiple, but can be applied to have only two kinds of professional video display light fixture: first sector structure, this structure are similar to a umbrella; The every lamp plate that LED is installed (circuit board or aluminium base) all is fan-shaped, is a circle after the splicing, is that fixing point also is a point on every side; The center is removable; Its advantage is simple in structure, but the angle adjustable scope is little, and hot spot central point brightness meeting descends to some extent when surpassing the intrinsic irradiating angle of 1.5 times LED; Center spot brightness descends very greatly when surpassing the intrinsic irradiating angle of two times LED, the center blackening occurs; It two is by the yellow brave refined a kind of LED projection lamp with adjustable angle that provides of inventor; Its working method be with four or more polylith the plate (circuit board or aluminium base) of LED lamp pearl is housed; Be contained in respectively on the pivotable sole plate that is positioned at base; Each base plate is all having a rotating axle near the centre, be used to adjust the angle of base plate and base, changes the direction of illumination of lamp onboard led lamp pearl with this.Its major defect is that adjustable angular range is less, and hot spot if lamp plate sum in outer ring is few, also has the even phenomenon of multiple spot uneven illumination when surpassing the intrinsic irradiating angle of two times LED except that the central point deepening.
In sum, above dual mode all is based on the individual pen adjustable structure, and its defective is that angle adjustable can not be greater than the intrinsic irradiating angle of two times LED, hot spot uneven illumination phenomenon in all effective range of exposures when being transferred to maximum angle.
Summary of the invention
