Description

A kind of LED fluorescent lamp

Technical field

The utility model relates to the lighting device technical field, specifically relates to adopt the fluorescent lamp of LED as light source.

Background technology

Fluorescent lamp near the durable type electric light source of " daylight ", has been used over half a century as a kind of comparatively energy-conservation and light, has formed the whole world most widely used worker's domestic lighting device all the time.But fluorescent lamp also has its intrinsic shortcoming, and its fluorescent tube fragility is easily broken, and structure is comparatively complicated, needs ballast starter etc. as appurtenances mostly, and general ten thousand hours life-span of less than also can not be satisfied people's demand gradually.

Along with the proposition of " energy-conservation " and " green illumination " theory, integrate the appearance of the LED (Light-emittingdiode, light emitting diode) of various advantages, the arrival that is declaring publicly new solid light source epoch undoubtedly.LED is a kind of semiconductor that electric energy can be converted into visible light, it changed the incandescent lamp tungsten filament luminous with the luminous principle of energy-saving fluorescent lamp tricolor powder, and adopt electroluminescence, have long, numerous advantages such as light efficiency is high, radiationless and low-power consumption of life-span.The spectrum of LED almost all concentrates on visible light frequency band, and luminous efficiency can reach 80-90%, near the limit of electric light conversion; Light quality height, essentially no radiation belongs to typical green illumination light source; Life-span is especially near 1,000,000 hours, and is reliability and durability, and maintenance cost is very cheap.

Though LED has so many advantage, at present rarely seen with LED be light source the general lighting device.This mainly is because single LEDs light quantity is generally less, realizes conventional brightness illumination as need, needs the tens of LED lamp of intensive installation, and it is a problem that must solve that so intensive and LED quantity are carried out good heat radiation.And the optical beam ratio of LED is more concentrated, and angle is very narrow, can not reach the astigmatism of illumination as ordinary lamps, therefore, adopts LED also need be further improved as fluorescent light source.

The utility model has following remarkable result compared to existing technology:

1, the utility model is installed in several LED lamps on the aluminum pcb board, simultaneously the heat conduction aluminium block being set on pcb board is connected with the lamp body shell, can be fully effectively on the heat that is come out on the LED lamp be set discharge outside the lamp body, guaranteed the operate as normal of LED fluorescent lamp.

2 and light source of the present utility model is luminous downwards following of the effect of Lamp cup, cut the waste, so light source actual effect rate is higher, be provided with a rotational structure on one's body at fluorescent tube simultaneously, fluorescent tube can be rotated, thereby can adjust the light fixture range of exposures as required.

3, lamp body length of the present utility model can customize as required, can be installed on the ceiling, also can be installed in the sales counter, and is practical.

4, provided by the utility model with LED as the light source fluorescent lamp, luminosity is bright, little power consumption, long perfomance life is durable, security reliability is good, than general daylight lamp energy-saving 70%, and the no stroboscopic of turning on light, helps environmental protection.

Description of drawings

The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.

Fig. 1 is a surface structure schematic diagram of the present utility model.

Fig. 2 is a parts decomposing schematic representation of the present utility model;

Fig. 3 is the decomposing schematic representation of rotatable parts of the present utility model.

The specific embodiment

Referring to Fig. 1～3, a kind of LED fluorescent lamp, its main body is made of the led light source assembly, light source assembly includes the some LED lamps 5 that are installed on the pcb board, pcb board is the aluminum plate that design has circuit, the spacing of LED lamp is installed on the pcb board, and the length of number and pcb board 6 can be according to the required customization of reality.Be covered with reflector 51 on each LED lamp on the pcb board face, reflector is provided with the protection light microscopic 52 of arc, and the light that reflector is used for LED is sent converges downwards, to increase luminous intensity.

Light source assembly is that fixed sealing is contained in the fluorescent tube housing 2, offers loophole 21 on the fluorescent tube housing, and the position of the LED lamp on the position of loophole and the pcb board is corresponding, and the loophole of fluorescent tube housing seals by the protection light microscopic that is provided with on the LED lamp again.The fluorescent tube housing is aluminium matter tubular shell, and is easy to process, not only firmly but also be beneficial to heat radiation.Light source assembly and being connected of fluorescent tube housing are by the fixing heat conduction aluminium block 61 at the back side of pcb board, the heat conduction aluminium block are screwed on the fluorescent tube housing again.In order to make LED fluorescent lamp good looking appearance, on the fluorescent tube housing, offer dovetail groove 22, the screw that heat conduction aluminium block and fluorescent tube housing are fixed together is arranged in the dovetail groove, and dovetail groove with 7 encapsulation of shutoff bar, forms a complete light integral body again.Pcb board in the fluorescent tube housing links together by heat conduction aluminium block and light housing, can be fully effectively on the heat that is come out on the LED lamp be set be dispersed into outside the lamp body, guaranteed the operate as normal of LED fluorescent lamp.

The utility model also is being provided with the runner assembly that lamp body is rotated, and runner assembly includes tape spool termination plug 11, and part 15, spring 13 and clamp nut 14 are changeed in termination with holes plug 12, resistance.The cross section of the axial region termination of tape spool termination plug is an oval shape, the shape of through holes that resistance commentaries on classics part center is offered and the axial region termination form fit of tape spool termination plug.During assembling, termination with holes plug sleeve is on the axial region 110 of tape spool termination plug, the axial region termination of tape spool termination plug leans out termination with holes beyond the Great Wall, again part being changeed in resistance is enclosed within on the axial region termination of tape spool termination plug, after adding upper spring, resistance commentaries on classics part and termination with holes plug are fixed on the tape spool termination beyond the Great Wall with clamp nut.
