Abstract
The utility model relates to a light emitting diode (LED) lighting fixture, in particular to an anti-dazzle structure of the LED lighting fixture. The anti-dazzle structure comprises a lighting fixture shell body, the upper portion of the lighting fixture shell body is not sealed, sealing is achieved through an armored glass plate, and a base is formed on the lower portion of the lighting fixture shell body. The anti-dazzle structure further comprises an aluminum base single-surface circuit board arranged on the base and a luminophor arranged on the circuit board, and further comprises a shell body end cap arranged on the aluminum base single-surface circuit board and used for fixing the luminophor. The anti-dazzle structure is characterized by further comprising grating plates arranged in the lighting fixture shell body, and the grating plates are located between the luminophor and the armored glass plate. Compared with the prior art, most light rays emitted by an LED light source to a lens rough surface can be absorbed by the grating plates, a small part of the light rays can be reflected, the light rays reflected through the surface are weak, and dazzle effects are not enough to be caused.
Description
Technical field
The utility model relates to a kind of LED lighting, is exactly a kind of glare prevention structure of LED lighting specifically.
Background technology
In the situation that global energy is short, environmental requirement improves constantly, illuminating industry traditional lighting light fixture is in the past substituted by the Novel LED energy-saving light fixture gradually.Because the LED light efficiency is high, (the highest light efficiency in laboratory has reached 161lm/w(cree at present) is the highest illuminating product of present light efficiency.) good stability, the response time is exceedingly fast (response time of LED lamp is nanosecond), and glow color is pure, and non-variegation light covers whole wave bands of haveing suffered visible light, and this all reason causes the LED lighting more and more to be pursued.And more and more along with the LED light fixture, its some drawbacks are also inevitable.Led light source brightness is higher, therefore also is easy to form the vision dazzle.
Dazzle is one of major reason that causes visual fatigue, may cause detest, uncomfortable, seriously can cause human visual forfeiture function.Used underground lamp or Projecting Lamp, street lamp etc. are all kept away unavoidable meeting and are looked at straight by human eye on the general square, and this can cause high light directly to enter people's the visual field, thereby causes dazzle, cause human body uncomfortable.Gently then cause in vision a period of time uncomfortable, heavy then can cause that the human eye retina descends to the contrast of picture, thereby cause brain difficult to the parsing of imaging.Therefore, prevent that in lighting dazzle is particularly important, and LED lighting local luminance is higher.Common light fixture adopts the way that adds a reflector and lens are set before the LED light fixture, has certain effect to improving dazzle, but DeGrain.
Summary of the invention
The utility model provides a kind of glare prevention structure of LED lighting in order to overcome the deficiencies in the prior art.
To achieve these goals, the utility model has designed a kind of glare prevention structure of LED lighting, comprise lamp casing, the top of lamp casing is what do not seal, adopt armorplate glass to seal, the below forms base, also comprise the aluminium base one-sided circuit board that is arranged on the base, and setting illuminator in the circuit board, comprise that also one is arranged on the aluminium base one-sided circuit board and is used for the fixedly housing end plug of illuminator, it is characterized in that: also comprise the flase floor that is arranged in the lamp casing, flase floor is between illuminator and armorplate glass.
Described illuminator comprises lens, and the led light source that is positioned at lens.
The utility model is compared with prior art, has following characteristics:
The light that A, led light source are mapped on the lens matsurface can be absorbed by grid mostly, and seldom part can reflect, and is very weak through the light of this surface launching, is not enough to cause glare effect.
B, because most light are reflected to and are illuminated object, so the brightness meeting of this object increases, thereby improve the utilization ratio of light source, and saved energy resource consumption.
C, to shine the distribution of light that is illuminated body surface after reflection relatively even, thereby avoided crossing bright area and dark space.
Description of drawings
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
Referring to Fig. 1,9 is lamp casing; 10 is armorplate glass; 11 is base; 12 is aluminium base one-sided circuit board; 13 is lens; 14 is led light source; 15 is housing end plug.
Referring to Fig. 2,1 is lamp casing; 2 is armorplate glass; 3 is base; 4 is aluminium base one-sided circuit board; 5 is lens; 6 is led light source; 7 is flase floor; 8 is housing end plug.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, existing LED illuminating lamp comprises lamp casing 9, the top of lamp casing 9 is what do not seal, adopt armorplate glass 10 to seal, the below forms base 11, also comprises the aluminium base one-sided circuit board 12 that is arranged on the base 11, and is arranged on the illuminator on the wiring board 12, illuminator comprises lens 13, and is positioned at lens 13 and comprises led light source 14.Comprise that also one is arranged on the aluminium base one-sided circuit board 12 and is used for the fixedly housing end plug 15 of illuminator.
In should existingly designing, when illuminating lamp was worked, its light can directly enter the visual field of human body, not only wastes energy, and easily causes dazzle, caused human body uncomfortable, and serious meeting causes human visual forfeiture function.
As shown in Figure 2, the utility model comprises lamp casing 1, the top of lamp casing 1 is what do not seal, adopt armorplate glass 2 to seal, the below forms base 3, also comprise the aluminium base one-sided circuit board 4 that is arranged on the base 3, and be arranged on the illuminator on the aluminium base one-sided circuit board 4, illuminator comprises lens 5 and led light source 6.Comprise that also one is arranged on the aluminium base one-sided circuit board 4 and is used for the fixedly housing end plug 8 of illuminator, be with the difference of prior art, also be provided with flase floor 7 in the lamp casing, flase floor 7 is between illuminator and armorplate glass 2.
Compare with prior art, have following characteristics:
The light that A, led light source are mapped on the lens matsurface can be absorbed by grid mostly, and seldom part can reflect, and is very weak through the light of this surface launching, is not enough to cause glare effect.
B, because most light are reflected to and are illuminated object, so the brightness meeting of this object increases, thereby improve the utilization ratio of light source, and saved energy resource consumption.
C, to shine the distribution of light that is illuminated body surface after reflection relatively even, thereby avoided crossing bright area and dark space.
