Description

The LED fluorescent lamp

Technical field

The utility model relates to the fluorescent lamp technical field, especially a kind of LED fluorescent lamp.

Background technology

Because the LED light fixture has the high low in power consumption of long light efficiency of life-span, progressively be designed to the fluorescent lamp pattern and substituted traditional fluorescent lamp, but existing LED fluorescent lamp is provided with circuit board and led array mostly in the body of fluorescent tube, the LED illuminator is generally arranged along the body axial direction, the LED illuminator go out the tube wall of light center towards body, this structure LED illuminator is being coated by body, it is bad to dispel the heat, the life-span and the luminous efficiency of LED illuminator have been influenced, be not suitable for the high-power LED illuminator, on the other hand because fluorescent tube is the array arrangement, fluorescent tube quantity is many, and have certain color temperature difference to be difficult to control uniformity of light and angle between fluorescent tube and the fluorescent tube, it is undesirable to go out light effect.

The utility model content

The technical problems to be solved in the utility model provides a kind of LED fluorescent lamp with good heat radiating function, effectively ensures LED lamp life-span and luminous efficiency, and it goes out the more approaching traditional fluorescent lamp of light effect, and light is softer.

For achieving the above object, the technical solution of the utility model is: a kind of LED fluorescent lamp, comprise light pipe, be arranged at LED lamp in the light pipe, be installed in the radiating block at light pipe two, light pipe top also is provided with a circular arc heat sink strip, and the radiating block at described circular arc heat sink strip two ends and light pipe two is interlockingly connected.

Above-mentioned LED fluorescent lamp, described LED lamp is arranged on two of light pipe, two LED lamp exiting surface is provided with in opposite directions, this LED lamp be arranged so that the LED fluorescent lamp go out the more approaching traditional fluorescent lamp of light effect, light is softer.

Further, above-mentioned LED lamp exiting surface the place ahead is provided with the secondary optics reflector, two secondary optics reflectors are arranged on the two ends of light pipe, two secondary optics reflector reflective surfaces are provided with in opposite directions, the LED lamp is separately positioned on the bottom centre of secondary optics reflector, because of setting up the secondary optics reflector, improve leaded light efficient.

Above-mentioned LED fluorescent lamp, described radiating block is provided with the groove of fastening circular arc heat sink strip, and radiating block and circular arc heat sink strip are that aluminium alloy and outer surface are equipped with heat radiation wing bar, further improve radiating effect.

Above-mentioned LED fluorescent lamp, described circular arc heat sink strip has wire hole, an inner surface and is provided with metallic channel, makes things convenient for circuit to install, and makes the whole LED fluorescent lamp seem more attractive in appearance.

Above-mentioned LED fluorescent lamp, described light pipe scribble optics nanometer optical waveguide layer, further improve light guide effect.

Owing to set up the heat sink strip of circular arc on the top of light pipe, the radiating block at circular arc heat sink strip two ends and light pipe two is interlockingly connected, increase area of dissipation greatly, the heat sink strip and the radiating block of the circular arc that the employing aluminium alloy is made have good thermal conductivity, heat that distributes by the LED lamp and the heat by the light pipe radiation just can distribute by radiating block and heat sink strip very soon, effectively ensure LED lamp life-span and luminous efficiency, this structure is suitable for installing than the high-power LED illuminator.

The specific embodiment

Below in conjunction with accompanying drawing and concrete embodiment the utility model is described in further detail.

Fig. 1, shown in Figure 2, a kind of LED fluorescent lamp, comprise light pipe 1, be arranged at LED lamp 2 in the light pipe 1, be installed in the radiating block 3 at light pipe 1 two, light pipe 1 top also is provided with a circular arc heat sink strip 4, the radiating block 3 at described circular arc heat sink strip 4 two ends and light pipe 1 two is interlockingly connected, and the also available screw of circular arc heat sink strip 4 and radiating block 3 tightens up mutually.

LED lamp 2 is arranged on two of light pipe 1, two LED lamp 2 exiting surfaces are provided with in opposite directions, LED lamp 2 exiting surface the place aheads are provided with secondary optics reflector 5, two secondary optics reflectors 5 are arranged on the two ends of light pipe 1, two secondary optics reflector 5 reflective surfaces are provided with in opposite directions, LED lamp 2 is separately positioned on the bottom centre of secondary optics reflector 5, and secondary optics reflector 5 also can be clamped the two ends that are fixed on light pipe 1 inner surface by band opening plastic hoop 6.

Radiating block 3 is provided with the groove 31 of fastening circular arc heat sink strip 4, and radiating block 3 is that aluminium alloy and outer surface are provided with heat radiation wing bar 32, and light pipe 1 scribbles optics nanometer optical waveguide layer 11.

Fig. 3, shown in Figure 4, circular arc heat sink strip 4 have wire hole 41, an inner surface and are provided with metallic channel 42, and the circular arc heat sink strip is that aluminium alloy and outer surface are provided with heat radiation wing bar 43.

LED lamp 2 can drive luminous by internal or external drive circuit, the heat that distributes after LED lamp 2 is luminous is earlier by radiating block 3 heat radiations, dispel the heat for circular arc heat sink strip 4 together by radiating block 3 conduction then, area of dissipation is big, radiating rate is fast, be fit to install the high-power LED illuminator, because LED lamp 2 luminous backs reflex to light pipe 1 by secondary optics reflector 5, around by optics nanometer optical waveguide layer 11 light being led again then, this LED fluorescent lamp go out the more approaching traditional fluorescent lamp of light effect, light is softer.

Heat sink strip of the present utility model is not limited to circular arc; well contact as long as can determine to form with the heat radiation at light pipe two; help heat conduction and can do various distortion; the shape of light pipe also can have various, and those skilled in the art is so long as make the protection domain that the change of unsubstantiality all falls into this case.
