The grating stripes can change the light path of the LED light source to make the shining angles of the lights more broad and uniform, and the discomfort of human eyes caused by directly viewing the LED fluorescent lamp can be effectively changed. The circuit board is welded with an LED driving circuit and a power supply circuit; the input and of the power supply circuit is electrically connected with the electrodes fixed on the lamp caps. The utility model has the characteristics of reasonable design, compact structure, and consistent standard with the prior fluorescent lamp, and can conveniently enters the prior illumination field to replace the prior fluorescent lamp; after processed with the grating lampshade, the illuminating lights are more soft, and people do not feel the glare when directly viewing the luminous body.

Description

A kind of LED fluorescent lamp

Technical field:

The utility model belongs to lighting field, and particularly a kind of LED of employing is the daylight lamp apparatus of light source.

Background technology:

Fluorescent lamp is as cold light source, and it is energy-conservation than conventional incandescent, is widely used in industry and domestic lighting, and accessories such as the lamp bracket supporting with it, lamp socket or lamp box have formed standard.Development along with new-type light source led, it also becomes inevitable in the lighting field utilization, but LED lamp type, light path and traditional fluorescent lamp greatly differ from each other, if it is designed to the fluorescent lamp shape, to produce active influence to popularizing of new light sources, the use occasion and the user of light source accept psychology, can accomplish to seamlessly transit.The scheme of several these thinkings is also disclosed in patent gazette at present, but all have fluorescent tube or be called the unreasonable of lampshade design, for lossless printing opacity promptly need adopt Transparent lamp shade, this structure LED point source of light leaks, the light path illumination angle is little, and the perverse eye of LED, the fluorescent lamp that is combined into becomes point-like straight line shape, allows the human eye incompatibility, for this reason, there also have the designer that LED is arranged in to be wavy, in the hope of improving its sense organ effect, but all can not achieve one's goal; Moreover the LED supply voltage is lower, for being applicable to civil power, needs supporting power circuit, and numerous patents are all made power circuit tradition " ballast " form, are placed on the lamp bracket, imitate fluorescent lamp on the structure fully.

Summary of the invention:

The purpose of this utility model is a kind of light path of design and outward appearance and the similar LED fluorescent lamp of traditional fluorescent lamp pipe.

Technical solutions of the utility model are achieved in that a kind of LED fluorescent lamp, the lamp holder that comprises class fluorescent tube shape lampshade, two ends covers, is hubbed at the circuit board that is welded with LED in the lampshade, circuit board is electrically connected with being fixed on the electrode that lamp holder covers, and wherein lampshade is provided with axial grating line at least on LED direct projection zone.The grating line can make the led light source light path change, and the light illumination angle is broad more and even, and effectively changes the sense of discomfort of the direct view led fluorescent lamp of human eye.

Be welded with led drive circuit and power circuit on the described circuit board, the input of power circuit is electrically connected with the electrode that lamp holder covers.Except welding LED, also led drive circuit and power circuit are together welded onboard on the circuit board, and together in the lampshade, form integrated design.

The utlity model has reasonable in design, compact conformation, with the characteristics of traditional fluorescent lamp conformance to standard, can conveniently cut existing lighting field, substitute traditional fluorescent lamp, through the processing of grating lampshade, the light of irradiation is more evenly soft, not perverse eye during human eye direct-view illuminator.

The specific embodiment:

See figures.1.and.2, the LED fluorescent lamp, comprise the class fluorescent tube shape lampshade of making by transparent material 1, the lamp holder lid 2 at two ends, one block welding has the circuit board 4 of LED3, drive circuit and power circuit to be hubbed on lampshade 1 board slot 11, the input of circuit board 4 is electrically connected with electrode 21 on being fixed on lamp holder lid 2, and the drive circuit power supply is provided.Wherein lampshade 1 is provided with axial grating line 12 on LED direct projection zone, the light irradiating angle that LED light reflects through lampshade grating line 12 is broad more, and human eye sees is not point-like led light source one by one, but the ring-type light belt of ring by ring, irradiation area is bigger, and light is softer.

In the legend, the tubulose section bar of lampshade 1 for stretching and forming, top is that class is rectangular-shaped, and the installing space of drive circuit and power circuit is provided, LED direct projection zone in bottom is the semicircle arcuation, makes the light of refraction even, no dead angle and highlight bar.The tubular structure of 1 one-tenth sealing of lampshade, its rigidity is strong, can directly use in the occasion of no lamp bracket.

The perpendicular wall inboard of described lampshade 1 rectangular section symmetry is provided with the board slot 11 of the circuit board 4 that is pivoted, and the rectangular section upper end slightly becomes the waisting shape, and forming one can be by the catching groove 13 of location such as lamp bracket 5 objects such as grade, as shown in Figure 4.

In order to guarantee that good heat radiation is arranged in the fluorescent tube, condition oneself to long hours of work, so be provided with air inlet through hole 22 on lamp holder lid 2, tubulose lampshade 1 top is provided with heat radiation through hole 14, circuit board 4 offers louvre 41 at no element region.After the LED of fluorescent lamp lights, temperature rises in the lampshade 1, thermal current is promptly discharged by a plurality of heat radiation through holes 14 of a plurality of louvres 41 on the circuit board 4 and lampshade top, the environment cold airflow promptly enters formation air-flow circulation in the lampshade by the air inlet through hole 22 of two lamp holders lid simultaneously, suppress temperature rise in the lampshade, prolong the service life of each element.

With reference to Fig. 2 and Fig. 3, the electrode 21 of the lamp holder of lampshade 1 lid 2 can be as shown in Figure 2 outer male structure, it can be used on the traditional fluorescent lamp lamp bracket, and the interior concave electrode 21 among Fig. 3, can be used as on the integrated illumination equipment or can many fluorescent tubes serial connection or the use occasion that connects together.

With reference to Fig. 4 and Fig. 5, Fig. 4 is and lamp bracket 5 is formed complete light fixture product, can apply to office, roof lighting at home, and lamp bracket 5 provides the facility that is fixed on the roof, and is attractive in appearance and globality is strong.And Fig. 5 is for providing easy fastener 6, these fastener 6 both sides have the buckle teeth 61 that can buckle in the lampshade catching groove 13, only need during installation fastener 6 is installed on the object, then lampshade 1 is pressed into and gets final product, be convenient to use on some emergent occasions and the environment such as decorated wall surface, lamp box.

With reference to Fig. 6, the tubular structure of lampshade 1 in last example, also can be the groove shape section bar that stretches and form, also be that top is open slot.Its top cell wall is a vertical, and LED direct projection zone in bottom is the semicircle arcuation, and the cell wall upper end is provided with can be by the catching groove 13 of location such as lamp bracket 5 objects such as grade, and the lampshade 1 of this structure can cooperate with whole lamp bracket 5.
