Abstract
A fluorescent tube lamp includes a lamp tube, a fluorescent lamp installed on the lamp tube and an anti-dazzle grid. The lamp tube is provided with a cylindrical cavity, a light outlet is formed in one end of the lamp tube, and the other end of the lamp tube is a sealed end. A lamp holder hole is formed in the side wall of the lamp tube. A light emitting part of the fluorescent lamp penetrates through the lamp holder hole. The anti-dazzle grid is mounted at the light outlet off the lamp tube and includes a first arc light shield plate, a second arc light shield plate, a third arc light shield plate, two planar light shield plates and two connection cross beams. The first arc light shield plate and the second arc light shield plate are opposite to each other and protrude outwards. Two ends of each planar light shield plate are fixedly connected with two ends of the first arc light shield plate and the second arc light shield plate respectively, and the first arc light shield plate and the second arc light shield plate together form a first light shield tube. The third arc light shield plate and the second arc light shield plate are opposite to each other and protrude outwards and together form a second light shield tube. The fluorescent tube lamp can prevent human eyes from seeing the fluorescent lamp without adding the depth of a reflector of the light outlet of the lamp tube or changing light distribution, and thus achieves the anti-dazzle purpose.

In other embodiments, two planar shaped shadow shields 131 are parallel to be oppositely arranged, first arc shadow shield 133, second arc shadow shield 134 and the 3rd arc shadow shield 135 are the equal semicircular arc of radius of curvature, and to make the second cone 139 for circular cylinder, the first cone 138 is kidney-shaped cylinder.
Further, the illuminating part 123 of the corresponding fluorescent lamp 120 in the center of circle of the second cone 139 is arranged, two connecting cross beams 137 are fixedly connected with the middle part of the first arc shadow shield 133 and the second arc shadow shield 134 respectively, and two connecting cross beams 137 are parallel to two planar shaped shadow shields 131 arranges.
Further, the internal diameter of the second cone 139 is less than or equal to the half of the internal diameter of lamp cylinder 110, to block the dazzle that fluorescent lamp 120 sends to greatest extent.
Further, the inwall of the light-emitting window 111 of lamp cylinder 110 is provided with two symmetrically arranged draw-in groove (not shown), and two connecting cross beams 137 hold with draw-in groove mutually away from one end of cone.Due to the fixed form that anti-dazzle grating 130 adopts connecting cross beam 137 to fasten with the draw-in groove of lamp cylinder 110, be convenient to change anti-dazzle light source and fluorescent lamp 120.
Further, each connecting cross beam 137 is the laminated structure of strip, and the axis that each connecting cross beam 137 is all parallel to lamp cylinder 110 is arranged; The outermost side of two connecting cross beams 137 all flushes in the openend setting of light-emitting window 111.
Because each connecting cross beam 137 is the laminated structure of strip, and the axis that each connecting cross beam 137 is all parallel to lamp cylinder 110 is arranged, and the light avoiding connecting cross beam 137 pairs of fluorescent lamps 120 to launch blocks, and improves the utilization rate of light.In addition, the light-emitting window 111 that the outermost side of two connecting cross beams 137 all flushes in lamp cylinder 110 is arranged, and avoids the shaded effect of the light-emitting window 111 of connecting cross beam 137 pairs of lamp cylinders 110 to impact.
Refer to Fig. 6 and Fig. 7, preferably, it is first gear optic angle that fluorescent lamp 120 is injected into the angle that planar shaped shadow shield 131 is positioned at the light of the side outside the light-emitting window 111 of lamp cylinder 110 and the central shaft of the second cone 139, and first gear optic angle is 29.91 ± 5 degree; It is second gear optic angle that fluorescent lamp 120 is injected into the angle that the first arc shadow shield 133 is positioned at the light of the side outside the light-emitting window 111 of lamp cylinder 110 and the central shaft of the second cone 139, and second gear optic angle is 28.10 ± 5 degree; It is third gear optic angle that fluorescent lamp 120 is injected into the angle that the second arc shadow shield 134 is positioned at the light of the side outside the light-emitting window 111 of lamp cylinder 110 and the central shaft of the second cone 139, and third gear optic angle is 21.88 ± 5 degree.
With specific embodiment, above-mentioned fluorescent drum-type lamp 100 is described below.
Fluorescent lamp 120 is the U-shaped power saving fluorescent lamp 120 of 36 Wa Ousilang.The diameter of the light-emitting window 111 of lamp cylinder 110 is 215, and light-emitting window 111 is 98mm to the degree of depth of bottom.After having added anti-dazzle grating 130, first gear optic angle narrows down to 29.91 degree from 63.47 degree, and second gear optic angle narrows down to 28.10 degree from 73.47 degree, and third gear optic angle narrows down to 21.88 degree from 56.01 degree.
Refer to Fig. 8 and Fig. 9, Fig. 8 is the distribution curve flux figure that the fluorescent drum-type lamp 100 of above-described embodiment does not add anti-dazzle grating 130; Fig. 9 is the distribution curve flux figure after the fluorescent drum-type lamp 100 of above-described embodiment has added anti-dazzle grating 130.By simplation verification, to add after anti-dazzle grating 130 luminous intensity distribution without too large impact.
Installed and used by test, the comparatively satisfaction of test effect, only have immediately below the light-emitting window 111 that tester goes to lamp cylinder 110, head lifts Shi Caineng and sees light source, experience dazzle, walk below the light-emitting window 111 of lamp cylinder 110 under normal circumstances and also can not labour contractor lift in that way, so anti-dazzle is effective.
The light-emitting window 111 of above-mentioned fluorescent drum-type lamp 100 is provided with anti-dazzle grating 130, the light inlet end of anti-dazzle grating 130 is positioned at the inner side of light-emitting window 111, light-emitting window end is positioned at the outside of light-emitting window 111, thus make anti-dazzle grating 130 pairs of fluorescent lamps 120 be irradiated to the dazzle interception of personnel, but do not affect the illumination that the light-emitting window 111 of lamp cylinder 110 is downward, thus when need not increase the degree of depth of the reflection shield of the light-emitting window 111 of fluorescent drum-type lamp 100 and change luminous intensity distribution, avoid human eye can see fluorescent lamp 120, to reach anti-dazzle object.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It 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.
