The specific embodiment
For further understanding feature of the present invention, technological means and the specific purposes that reach, function, below in conjunction with accompanying drawing and the specific embodiment, the present invention is described in further detail.
As extremely shown in Figure 5 in Fig. 1, light fixture lampshade of the present invention comprises lamp housing 10, bullet 20 and LED lamp source 30, described lamp housing 10 is the reverberation bowl structure, described lamp housing 10 cross sections roughly are " U " shape, described lamp housing 10 comprises base plate 11 and annular slab 12, described annular slab 12 is located in around described base plate 11, described annular slab 12 is provided with mild section 121, Multi reflection section 122, secondary reflection section 123 and primary event section 124, and described mild section 121, Multi reflection section 122, secondary reflection section 123 and primary event section 124 curvature progressively increase successively.
Described LED lamp source 30 is fixedly installed on base plate 11, the fixing coupling of described bullet 20 is arranged on 30 tops, described LED lamp source, the cross section of described bullet 20 is " V " shape, described bullet 20 downside surfaces are coated with reflector layer, reflect with the light that LED lamp source 30 is launched, the congregational rate of reduction LED lamp source 30 emission of lights reduces the optically focused phenomenon.described bullet 20 is provided with parallel reflective faces 21, on penetrate light reflection face 22 and injection light reflection face 23 multiple cambers structures, described parallel reflective faces 21, on penetrate light reflection face 22 and injection light reflection face 23 level inclination increase successively, carry out in an orderly manner reflex with the light that LED lamp source 30 is sent, make from described parallel reflective faces 21, on penetrate the light that light reflection face 22 and injection light reflection face 23 reflect away and can arrive on annular slab 12, the light that the reflex again of utilizing annular slab 12 is sent LED lamp source 30 carries out scattering, reduce the dazzle impact that source 30 direct projections of LED lamp cause.
The all edges of light fixture lampshade of the present invention shaft core direction is followed successively by focal zone 40, middle focal zone 50 and lower focal zone 60 from top to bottom, described upper focal zone 40 and middle focal zone 50 are above described bullet 20, described lower focal zone 60 is below described bullet 20, described LED lamp source 30 emits beam, and scattering enters in 40 scopes of upper focal zone after lamp housing 10 and bullet 20 Multi reflection effects, makes upper focal zone 40 scopes change by cone governor body 20 and base plate 11 spacings; Described middle focal zone 50 be reflection ray through the blind area, described LED lamp source 30 emits beam and arrive lower focal zone 60 after 23 reflection of injection light reflection face.
Through theoretical research for many years and practice, invented the dazzle principle analysis theoretical, the differentiation of distinct dazzle light beam and non-dazzle light beam is the concept of critical projectional angle, and namely critical projectional angle refers to that light should be controlled crevice projection angle in the Design of Luminaires of projection from the top down.When light is invested ground greater than critical projectional angle, there is part light (being dazzle) can directly inject eyes under normal visual angle (looking squarely); During only less than critical projectional angle, all light just can directly not injected eyes under normal visual angle (looking squarely), can not produce dazzle.
The computing formula of critical projectional angle Φ is: tan Φ=C/(A-B), wherein A be street lamp to the distance on ground, B is the health height of test person, C is human body to LED lamp source 30 perpendicular to the vertical range of the straight line on ground.
the present invention is according to above-mentioned theory and critical projectional angle principle after tested, design lamp housing 10 and bullet 20 in the light fixture lampshade, namely adopt bullet 20 and lamp housing 10 to control lighting angle or the zone in LED lamp source 30, satisfy the requirement of critical projectional angle, bullet 20 is controlled at illumination beam in the effective lighting scope and critical projectional angle of overtesting and test fully with the reflex of lamp housing 10 like this, make effective lighting scope illumination more even, and dazzle light beam change direction can be become effective irradiation light, anti-dazzle is effective, thereby can effectively eliminate the purpose that light pollution has reached anti-dazzle, by the design of critical projectional angle, make that scattered beam in upper focal zone 40 is more even, the free from glare sense.
LED lamp of the present invention source 30 emission of lights, wherein a part of light arrives in 60 scopes of lower focal zone after reflecting through injection light reflection face 23; Wherein another part light emission is to bullet 20, come back reflective between bullet 20 and lamp housing 10, form Secondary Emission light, four secondary reflection light, six secondary reflection light and eight secondary reflection light, simultaneously a part of light emission is to the primary event section 124 of lamp housing 10, and light direct projection after 124 reflections of primary event section is gone out; LED lamp source 30 emits beam through after penetrating light reflection district's reflection on bullet 20, pass through again mild section 121 and reflected in parallel district secondary reflection again, arrive Multi reflection section 122, utilize the theoretical emission of critical projectional angle to enter upper focal zone 40, light 40 li of upper focal zones is more even, the free from glare sense; Simultaneously LED lamp source 30 emits beam and arrive the secondary reflection district after parallel reflective faces 21 reflection, secondary reflection is laggard again the secondary reflection district enter in 40 scopes of focal zone.
In sum, light fixture lampshade of the present invention is by being provided with bullet 20 in lamp housing 10 couplings, the parallel reflective faces 21 of recycling bullet 20 design, on penetrate light reflection face 22 and injection light reflection face 23 multiple cambers structures carry out just secondary reflection, coordinate mild section 121, Multi reflection section 122, secondary reflection section 123 and primary event section 124 structures of lamp housing 10 designs to carry out secondary reflection again, make from LED lamp source 30 light that send more even, more without dazzling light sensation.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
