Accompanying drawing explanation
Fig. 1 is the cross-sectional view of a specific embodiment of LED fluorescent lamp of the present utility model;
Fig. 2 is the top view of the LED fluorescent lamp in Fig. 1.
The implication of Reference numeral: 1-PC cover in figure, 2-bonnet, 3-aluminium base, 4-2835 lamp pearl, 5-radiator.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
See figures.1.and.2, long-life anti-dazzle of the present utility model, without the LED fluorescent lamp of stroboscopic, comprising: PC cover 1 and bonnet 2, and the preferred high concentration PC cover of PC cover 1, PC cover 1 and bonnet 2 docking form circular cylindrical cavity.Also comprise: be arranged on radiator 5 and luminescence component in this circular cylindrical cavity.Wherein, be formed with shell draw-in groove and aluminium base draw-in groove on radiator 5, PC cover 1 and bonnet 2 are by the closed butt joint of shell draw-in groove, and the inside and outside surface of radiator 5 is all formed with the heat radiation projection of rib shape, and radiator 5 preferably adopts aviation aluminium to make; Luminescence component comprises: aluminium base 3, and 2835 staggered lamp pearl 4,2835 lamp pearl 4 coverings of two or more rows that are mounted on aluminium base 3 are equipped with high-quality glue, and the back side of aluminium base 3 is provided with circuit board.Aluminium base 3 is arranged on the end face of radiator 5, and is fastened in the aluminium base draw-in groove of radiator 5, is also provided with heat-conducting silicone grease (not shown) between radiator 5 and aluminium base 3.Circuit board is driven by the insulating power supply without stroboscopic, and insulating power supply is arranged in the cavity of radiator 5, and the lamp pearl drive current that this insulating power supply provides is below 40mA.
In the utility model, because 2835 lamp pearl 4 coverings are equipped with glue, not only can effectively reduce light decay and improve the antioxygenic property of lamp pearl, can also simplify manufacture craft; In addition, the drive current that insulating power supply provides is below 40mA, standard operation electric current (60mA) lower than 2835 lamp pearls 4, light decay was reduced to lower than thousand hours 1% by thousand hours 3%, extended greatly the service life of lamp pearl, although at this moment the brightness of lamp pearl declines to some extent, because having increased the quantity of lamp pearl, thereby the brightness of light fixture has been recovered, can not affect the normal use of light fixture; Employing, without the driving power of stroboscopic, can provide desirable DC current, drives lamp pearl to be operated under more satisfactory state, the light that lamp pearl sends like this, do not have any stroboscopic, can reduce greatly human eye caused visual fatigue under this light environment, play the effect of vision protection; The inside and outside surface of radiator 5 is all formed with the heat radiation projection of rib shape, and area of dissipation increases more than 3 times, has effectively improved radiating effect.
As a kind of preferred scheme, the external surface area of bonnet 2 is greater than the external surface area of PC cover 1, is guaranteeing to have under the prerequisite of larger lighting angle, suitably increases the ratio of the external surface area of bonnet 2 and the external surface area of PC cover 1, can improve radiating effect.
In the utility model, bonnet 2 preferably adopts the high plastics of leading to make.This height is led the thickness≤0.8mm of plastics, can conveniently dispel the heat, and can play again the effect of safe insulation.
The aluminium base 3 of light fixture, it is the passage that heat is distributed rapidly, thermal resistance must not be high, therefore aluminium base 3 preferably adopts the aluminium base of thermal conductivity factor >=1.5, so that the heat producing in the light fixture course of work, distribute fast, guarantee the work of the safety and stability of whole light fixture, to extend the service life of light fixture.Handle this link of heat radiation well, can make whole lamp work long hours, surface temperature is no more than 45 degree.
Because the high light direct projection of low colour rendering index, high color temperature and lamp pearl is the basic reason that produces dazzle, therefore when this Design of Luminaires, preferably adopt 2835 lamp pearls of high color rendering index (CRI), colour rendering index >=83, the lamp pearl that colour rendering index is high, the light sending is softer, warmth, not dazzling, can give very comfortable environment of operator; Aspect colour temperature, preferably adopting colour temperature on 5000-5500K lamp pearl left and right, excitation is higher, in this colour temperature section, is that LED lamp pearly-lustre is imitated a best region, also be the region that light relatively approaches natural daylight, the light sending on this region LED lamp pearl is very soft.Give the atmosphere of a kind of natural daylight of people.
In order to improve the radiating effect of whole light fixture, as a kind of preferred scheme, on bonnet 2, be formed with air-vent (not shown), increase circulation of air speed, accelerate heat radiation.
More preferably, this air-vent aperture is 0.5mm, and pitch-row is 10mm.
It should be noted that, above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
