The specific embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
In the LED antiglare illuminating lamp that the embodiment of the invention provides, change the dazzle regional perspective thereby be less than or equal to 5 degree through the control shielding angle, play anti-dazzle effect, improved luminous efficiency.
Fig. 3 shows the structure of the LED antiglare illuminating lamp that the embodiment of the invention provides, and for the ease of explanation, only shows the part relevant with the embodiment of the invention, and details are as follows.
The LED antiglare illuminating lamp comprises: led light source 10 and reflector element 11; Wherein led light source 10 is arranged on the bottom AB and CD of reflector element 11; The reflecting surface of reflector element 11 is positioned at the top of led light source 10, is used for the LED light of led light source 10 emissions is carried out secondary light-distribution to change the beam projecting direction of led light source 10; Shielding angle α 1 or α 2 are less than or equal to 5 degree; Shielding angle α 1 is line and the angle between the horizontal line between the bottom point B of top P and reflector element 11 of led light source 10; Shielding angle α 2 is line and the angle between the horizontal line between the bottom point D of top P and reflector element 11 of led light source 10.Visible by Fig. 3, shielding angle α 1 is greater than α 2, so as long as shielding angle α 1 is less than or equal to 5 degree.
In embodiments of the present invention, the size of shielding angle α 1 or α 2 reduces along with the increase of inclined angle alpha 3; Wherein inclined angle alpha 3 is the bottom AB of reflector element 11 and the angle between the horizontal line.
In embodiments of the present invention, be coated with diffuse-reflective material on the reflecting surface of reflector element 11.As one embodiment of the present of invention, be coated with reflectivity on the reflecting surface of reflector element 11 and be higher than 92% diffuse-reflective material; This diffuse-reflective material can adopt lambert's type diffuse-reflective material, and wherein, lambert's type diffuse-reflective material is a kind of whitewash of baric sulphur formula, can be coated on most metal, plastics, glass surface.The light that sends from led light source 10 is after the reflecting surface reflection of reflector element 11, and uniformity of illuminance reaches more than 80% in effective range, can effectively prevent direct glare.
Fig. 4 shows the luminous intensity distribution dazzle area schematic of the LED antiglare illuminating lamp that the embodiment of the invention provides, and for the ease of explanation, only shows the part relevant with the embodiment of the invention, and details are as follows.
Please consult Fig. 3 and Fig. 4 in the lump; The embodiment of the invention is designed to led light source 10 upwards luminous; Can change the position of led light source 10 on the bottom of reflector element 11 AB and CD as required; For example thereby the openend of AB and CD is provided with the variation that baffle plate is realized the shielding angle of LED antiglare illuminating lamp in the bottom can also to change reflector element 11 profiles; Do not have dazzle if will be controlled in the zone 21, then shielding angle α 1 or α 2 are less than or equal 5 degree, and human eye perceives is less than direct glare in this scope; In embodiments of the present invention; Can reach the purpose that changes the dazzle regional perspective through changing the position that inclined angle alpha 3 changes led light source 10; Make line PB or PD be up to the standard line position, then light fixture shielding angle vanishing this moment, free from glare zone fully if increase inclined angle alpha 3.
In embodiments of the present invention, when the luminous flux of led light source 10 was constant, the brightness and the area of light fixture were inversely proportional to; Adopt above-mentioned LED antiglare illuminating lamp can realize evenly throwing light on through led light source 10, light arrives human eye through at least one secondary reflection, and looking like this can be more comfortable; Because of led light source is the flood lighting that makes progress, dazzle zone 20 is on both sides, so can reach anti-direct glare effect effectively.
In embodiments of the present invention, the reflecting surface of reflector element 11 can be amounted to by the multistage planarea and form, and also can be amounted to by the multistage curvilinear plane to form, and can also be amounted to by multistage curvilinear plane and planarea to form.Wherein, the structure of the reflector element 11 of employing planarea 111 is shown in Fig. 5 A, and the structure of the reflector element 11 of employing upper convex surface 112 is shown in Fig. 5 B, and the structure of the reflector element 11 of concave curved surface 113 is shown in Fig. 5 C under adopting.
In embodiments of the present invention, through the surface light emitting brightness of change reflector element 11, thereby the inclined angle alpha 3 that changes led light source 10 reaches the purpose that changes the dazzle regional perspective, has played anti-dazzle effect.
In embodiments of the present invention, adopting four LEDs light sources is example, finds through the illuminating effect test experiment, adopts the above-mentioned LED antiglare illuminating lamp can be so that level of illumination visible reaches even; Can know that through the distribution curve flux check it is even that luminous intensity distribution can reach.
In embodiments of the present invention, reach the purpose that changes the dazzle regional perspective thereby be less than or equal to 5 degree through control shielding angle α 1, antiglare effect is good, and has improved luminous efficiency.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
