Abstract

The utility model provides a tubular LED (light-emitting diode) lamp, which comprises a cylindrical lamp body and an LED driving power supply, wherein the lamp body comprises a semi-cylindrical radiator, an LED light source arranged below the radiator and arranged in a strip shape, an arc lampshade shaded on the opposite side of the LED light source, and lamp caps arranged at two ends and matched with a T8 lamp tube; and the LED driving power supply comprises a power supply shell movably connected with the lamp body and a power supply driving board arranged in the power supply shell, the input end of the driving power supply is connected with the utility power, and the output end of the driving power supply is connected with the power supply end of the LED light source. The utility model provides the lamp which takes an LED as the light source and has the same shape as a fluorescent lamp; and because the power supply part comprising the driving board and the lamp body part comprising the LED light source are arranged separately, when the driving board is damaged, the power supply part can be conveniently removed and replaced by a new power supply part; therefore, the lamp is very convenient and simple.

Description

A kind of tubulose LED light fixture

Technical field

The utility model relates to lighting field, particularly a kind of LED light fixture.

Background technology

Light emitting diode (light-emitting diode LED) can send the light of certain brightness, and brightness can be regulated by electric current or voltage again, and itself is shock-resistant again, anti-vibration, and glow color is very abundant, and the transition of color is also very soft.Simultaneously service life long especially, it is reported life-span of LED lamp be ordinary incandescent lamp 20-30 doubly, be more than 10 times of conventional fluorescent lamps life-span.Therefore the LED light fixture has advantages such as power saving, life-span length as the alternative source of light in places such as the modern life, office because of it, is used very widely.The structure of existing LED light fixture generally includes the lamp holder that joins with power supply, in light fixture or lamp holder, be provided with the drive plate that is used for the driving LED light source, be installed in the radiator at the LED back side, led light source etc., wherein led light source is fixed by heat carrier and radiator, the a large amount of heats that distribute during the led light source operate as normal are dispersed in the air by radiator, to keep the normal working temperature of led light source, the fixing one that forms of radiator and lamp holder, such fitting structure is very simple and practical, but present stage, home-use light fixture major part was that gas-discharge lamp is (as fluorescent lamp, neon light, Halogen lamp LED, Metal halogen lamp etc.), particularly the fluorescent tube use is very extensive, for the lamp socket with current fluorescent lamp is complementary, directly uses existing bracket for fluorescent tube, now also have the LED light fixture is made the profile tubulose similar to fluorescent lamp, structure is as follows:

Tubular light fitting is divided into two parts up and down, and upper part is semicircular heat abstractor, and the bar-shaped LED plate of heat abstractor and below is close to, and is the lampshade of arc in the LED front, and LED power drives plate is arranged on and forms an integral body between radiator and the led board.But owing in general the life-span of led light source is longer than the life-span of LED power drives plate, such LED light fixture, when LED power drives plate damages, led light source may can also use for a long time, therefore, general only drive plate is partly changed, and incorporately like this be inconvenient to change drive plate as the light fixture of light source with LED.

Summary of the invention

In order to overcome in the prior art because LED power drives plate and radiator and led board are integrated, make LED power drives plate change inconvenient deficiency, the utility model provides a kind of tubulose LED light fixture, and the power panel of this LED light fixture and light fixture other parts constitute flexible connection.

The utility model for the technical scheme of finishing its technical purpose and adopting is: a kind of tubulose LED light fixture, comprise columned lamp body and LED driving power, described lamp body comprises half-cylindrical radiator, be arranged on the led light source that the strip below the described radiator is arranged, cover on the arc lampshade on described led light source opposite, the lamp holder that is complementary with the T8 fluorescent tube that is arranged on two ends, described LED driving power comprises outer casing of power supply that flexibly connects with described lamp body and the power drives plate that is arranged in the described outer casing of power supply, the input of described driving power links to each other with civil power, and output links to each other with the power end of described led light source.

Concrete, in above-mentioned a kind of tubulose LED light fixture: described LED driving power is arranged on the lamp holder of an end of described lamp body, also can be arranged on the described radiator.

The beneficial effects of the utility model are: the utility model provide with LED as light source and the light fixture fluorescent lamp appearance similar, partly partly separate setting owing to will comprise the power supply of drive plate with the lamp body that comprises led light source, when drive plate damages, can remove power unit easily, replace with new power supply partly, very convenient, simple.

Below in conjunction with the drawings and specific embodiments the utility model is done comparatively detailed description.
