Abstract

The utility model improves a transparent tube of an LED fluorescent lamp. The transparent tube is characterized in that crossed grid-bar shaped light-scattering stripes which are respectively spaced within 1 to 3mm are arranged on the wall face of a transparent tube body to form #-shaped reticulate patterns. With the function of the #-shaped reticulate patterns, an LED white point light source is transversely lengthened with better light scattering property; the lighting is more uniform and softer; the point light source becomes an anti-dazzling surface light source with softer lighting, and achieves the lighting effects basically similar to a common fluorescent lamp; human eyes basically do not have glaring feeling when looking directly into luminous bodies; moreover, long-time working under the lighting cannot cause glaring fatigue and injury to the human eyes, and the illumination basically has no losses.

Description

The transparent pipe of LED fluorescent lamp

Technical field

Utility model is the improvement of the transparent pipe of LED fluorescent lamp, and particularly White-light LED illumination daylight light dispersiveness and anti-glare are good, does not reduce the transparent pipe of illumination again.

Background technology

The led light source characteristic is that direct light is main, the irradiates light angle of divergence is little, bright dipping has stronger directionality, and luminous intensity height, particularly white light LEDs is typical dazzling point of vertical light source, the white light LEDs angle of divergence that for example is used to throw light on is to the maximum about the 80-120 degree, and single 0.06 watt of light intensity reaches 1600-2500mcd, lumen can reach 5-7lm, and one 15 watts white light LEDs fluorescent lamp needs about 240 LEDs.The white-light illuminating LED fluorescent lamp that high light intensity point of vertical light source like this is formed is very much perverse eye, and the eyes of working under this lamp shines are very much tired and uncomfortable, and permanent the use can be to human eye generation infringement, problems such as dizziness.People to improve illumination soften and diversity, do not make it become dazzling fixed fire light by improving transparent pipe for this reason.For example:

The disclosed LED sheen of Chinese patent CN1584389 lumiline lamp, the lighting material layer on the transparent tube body inner-wall spraying.But lighting material layer on the inner-wall spraying can cause the illuminance loss excessive, and increase making complexity and cost.The LED lighting device of Chinese patent CN201177216 solar simulated lamp, the low light efficiency blue-ray LED that adopts, the glass tube inwall applies red, yellow mixed fluorescent powder, or adopt low light efficiency purple light or ultraviolet leds, the glass tube inwall applies red, green, blue mixed fluorescent powder or white fluorescent powder, produces white light by applying fluorescent material.The method is because of inspiring white light with fluorescent coating, fluorescence coating density is big, resistance light is more serious, and lost entirely by the light of reflections from phosphor particles, cause illumination to reduce, for reaching the illumination identical with common fluorescent tube, built-in blue-ray LED or ultraviolet leds quantity and power must be added, and the high energy-saving effect of cost is not good.The disclosed LED fluorescent lamp of Chinese patent CN2766345, CN201053620 (1-3 with reference to the accompanying drawings), by be processed with axial grizzly bar shape striped 2 in transparent tube body 1 inboard, the grating effect that produces by striped reaches and improves the led light source astigmatism, make LED form strip astigmatism 3, broaden, evenly by irradiating angle, reach soft.Though by the axial grizzly bar shape striped of processing on transparent tube wall, can make the LED spot light produce the diffusing property of certain light, but it is actual because LED spot light direct projection characteristic, the dispersiveness of point of vertical light is still limited, the dazzling uncomfortable sensation of human eye is not eliminated yet fully, be difficult to reach similar fluorescent lamp lighting effect, under this illumination, work for a long time, eye fatigue still can occur with dizzy.Secondly, axial grizzly bar shape striped, what produce when disperseing led light source is long strip type light source 3, be the dispersion laying owing to form the LED of fluorescent lamp, can produce significantly bright dark separation like this, promptly produce strip illumination at the LED place, then just obviously deepening of light between LED, thereby it is limited to make that the illumination soften improves, and can produce glare equally.Therefore still having is worth improved place.

The utility model content

The utility model purpose is to overcome above-mentioned the deficiencies in the prior art, provides a kind of better to the LED spot light astigmatism property improved, the transparent pipe of LED fluorescent lamp that irradiation light is softer.

The utility model purpose realizes, the main improvement is to the transparent tube wall of grizzly bar shape striped LED fluorescent lamp at tape spool, increase again and intersect grizzly bar shape striped, for example circumferential ring grain, thereby form " well " word reticulate pattern, reach the dispersiveness of further improvement, strengthen the soft property of illumination the LED spot light, overcome the deficiencies in the prior art, realize the utility model order.Specifically, the transparent pipe of utility model LED fluorescent lamp, comprise that the tube wall face has the transparent tube body of axial grizzly bar shape striped, it is characterized in that the transparent tube body wall also has the grizzly bar shape striped that intersects with axial grizzly bar shape striped to form " well " word reticulate pattern jointly, axial and crossing grizzly bar shape striped grid are 1-3mm at interval.

" well " word reticulate pattern of the described formation of utility model can be the internal face at transparent pipe, also can be in the outside wall surface of transparent tube wall." well " word reticulate pattern, can be that axial grizzly bar shape striped is formed with vertical circumferentially ring grain, also can be that other can form " well " word reticulate pattern composition, and for example inclined shaft is to forming with the grizzly bar shape striped that intersects, utility model better adopts the former, and the diffusing property of light is relative with soften better.Grizzly bar shape striped is parallel stripes, can be the groove line, also can be stria, and utility model better adopts stria, and particularly the column structure stria is for example cylindrical or half-cylindrical, its astigmatic better effects if.

Transparent tube body is a prior art, can adopt the refractory light-transmitting plastic production, also can be that glass is made.

The transparent pipe of utility model LED fluorescent lamp, owing to be shaped on the fringe spacing on the transparent tube body surface is " well " word reticulate pattern that 1-3mm forms, transparent surface is become form the trickle lens of two-way row Fabric, make the effect of LED white point light source process " well " word reticulate pattern grating in length and breadth to all being elongated, better improved the light dispersiveness when white light LEDs is lighted, and the obvious bright dark space branch (Fig. 6) that does not have stick light, make through illumination more evenly soft, thereby become the gentleer anti-glare area source of illumination, have basic near common fluorescent lamp lighting effect, do not have dazzling sensation substantially during human eye direct-view illuminator yet, under this illumination, work long hours and can not cause thorn kopiopia and damage human eye.And illuminance is not lost substantially, with 1W large power white light LED contrast exposure experiments to light, electric current 350mA sees through light, the transparent pipe of the axial grizzly bar shape of prior art striped with the lumen machine testing, colour temperature 8154k, lumen 64.00lm, utility model colour temperature 8238k, lumen 64.44lm, show light intensity reduction useless, do not influence illumination substantially.
