Description

The LED planar lamp

Technical field

The utility model relates to lighting apparatus, relates in particular to the LED planar lamp.

Background technology

In places such as workbench, streamlines,, all need use lighting in order to guarantee normally carrying out of work.At present, these places are normally used is common fluorescent lamp.But common fluorescent lamp has some shortcomings.One, energy consumption is bigger, and the energy consumption of common fluorescent lamp is equivalent to four times of LED lamp; Two, frangible, all be glass lamp because common fluorescent lamp uses, to clash into the back broken easily receiving for glass lamp; Three, not environmental protection because mercury is all contained in common fluorescent lamp the inside, can pollute; Four, danger, what common fluorescent lamp used is the alternating current of 220V, so high voltage can damage human body; Five, life-span weak point, the ultralow life-span is that light fixture safeguards frequent.

Current also have some to use the product of LED illuminator as light emitting source, but these products all are that the LED illuminator is placed in the tube usually, process the fluorescent tube of emulation, and this product still needs light trough, and whole installation cost is relatively still higher.Alternative common fluorescent lamp with one to one, professional not strong, so being professional particular place, the LED flat lamp installs, have more hommization and professional.

The utility model content

The purpose of the utility model is that a kind of simple in structure, LED planar lamp that installation cost is low will be provided.

An aspect according to the utility model; The LED planar lamp that provides; Comprise dull and stereotyped lampshade, be overlying on diffuser plate and some the LED lamp bars that are loaded in the dull and stereotyped lampshade on the lampshade; Some LED illuminators are housed on the LED lamp bar, and diffusion is penetrated behind the part light direct irradiation diffuser plate that the LED illuminator sends.Its beneficial effect is that plate shaped through the monnolithic case of LED light fixture is processed, structure is more compact and simple, can well be applied under the environment such as workbench, streamline.Through using the LED illuminator, can effectively save energy consumption simultaneously, and the supply voltage that the LED illuminator uses is 12V-36V, can not produce injury, can effectively avoid potential safety hazard, assurance workman's personal safety human body as light source.The utility model also is applicable to environment such as office, classroom, underground garage and Working table simultaneously.

In some embodiments, dull and stereotyped lampshade is the rectangular structure of bottom opening, and diffuser plate is overlying on the bottom opening place of dull and stereotyped lampshade, and the wherein dull and stereotyped lampshade structure that is formed in one is taken into account reflecting part light source effect.Its beneficial effect is that whole dull and stereotyped lampshade adopts integrated formed structure, helps suitability for industrialized production, is beneficial to promoting the use of of LED planar lamp.

In some embodiments, the both sides of dull and stereotyped lampshade and back are provided with draw-in groove.Its beneficial effect is, through draw-in groove can with dull and stereotyped lampshade good be fixed on the workbench or streamline on, it is more convenient to install.

In some embodiments, the upper surface of dull and stereotyped lampshade is provided with some radiating fins, and radiating fin and dull and stereotyped lampshade are structure as a whole.Its beneficial effect is, because the LED illuminator on the LED lamp bar can produce great amount of heat, through radiating fin is set; Can effectively heat be conducted; Thereby the reduction temperature, so just can with the power of LED planar lamp do bigger, satisfy the different demands of different clients to brightness.

In some embodiments, facing mutually between the LED lamp bar is first reflecting plate, and the first reflecting plate horizontal fixed is on dull and stereotyped lampshade upper inner surface, and the part light that the LED illuminator sends penetrates from diffuser plate behind first baffle reflection.Its beneficial effect is, the light of this part normally can't penetrate from diffuser plate and go, but after first reflecting plate has been arranged, this a part of light just can obtain having utilized, thereby under equal conditions, has obviously increased the brightness of LED planar lamp.

In some embodiments, an outside side that is positioned at outermost two LED lamp bars respectively has the second skewed reflecting plate of one side, and two sides second reflecting plate is Eight characters shape, and the part light that the LED illuminator sends penetrates from diffuser plate behind second baffle reflection.Its beneficial effect is, the light of this part normally can't penetrate from diffuser plate and go, but after second reflecting plate has been arranged; Because second reflecting plate tilts; So this a part of light just can obtain having utilized, thereby under equal conditions, obviously increased the brightness of LED planar lamp.

In some embodiments, between the sidewall of second reflecting plate and dull and stereotyped lampshade be the accommodation space of a placement power supply.Its beneficial effect is effectively to save the space, and power supply is placed in the accommodation space, can also make the whole LED planar lamp more elegant in appearance, helps standardized production more.

In some embodiments, the some LED illuminators on the LED lamp bar are linearly arranged.Its beneficial effect is to guarantee the luminous more even of whole LED planar lamp.

In some embodiments, diffuser plate is that abrasive material is processed.Its beneficial effect is that the employing abrasive material can be so that the light that the LED planar lamp goes out be more soft.

In some embodiments, the two ends of LED planar lamp also are respectively equipped with end cap.Its beneficial effect is; Through end cap is set, make that the structure of whole LED planar lamp is more stable, effectively blocks dust gets in the light fixture; The cleaning of favourable maintenance lamp interior; Make the led light decay, light fixture effectively prolongs service life, can also prevent that the staff from being wounded by the corner of dull and stereotyped lampshade simultaneously.
