Description

A kind of rotatable LED fluorescent light

Technical field

The utility model relates to a kind of LED fluorescent lamp, relates in particular to a kind of rotatable LED fluorescent light.

Background technology

At present, for the LED industry that has just grown up, has only the fluorescent lamp of fixed-direction on the market.Because common fluorescent lamp is 360 degree luminous light source; And the led light source directionality is more intense; General maximum lighting angle is 120 degree; Can not satisfy the requirement of some application places, again not to the rotatable LED fluorescent light of LED fluorescent lamp exploitation, use for LED mouth light modulation product and cause certain blind area on the market; Therefore, there is certain limitation in application, is prone to cause the inconvenience in the use.For satisfying the needs in various places, a kind of rotatable LED fluorescent light simple in structure, reasonable in design, easy to use, applied widely is provided, with the application of expansion led light source, promptly become one of these those skilled in the art problem anxious to be addressed.

Summary of the invention

The utility model proposes a kind of rotatable LED fluorescent light to above-mentioned technological deficiency.

In order to solve the problems of the technologies described above, the technical scheme of the utility model is following:

A kind of rotatable LED fluorescent light comprises lampshade, aluminium shell, rotary connector, rotary connecting joint, lamp holder dop, metal clasp and lamp holder; The top that said aluminium shell is semicircle shape hollow and non-circular arc one side is connected through buckle with said lampshade; Identical and the outer surface of said aluminium shell two-end structure is the circular arc dentation, fixes at said aluminium shell one end and said rotary connector, and said rotary connector middle part hollow also is provided with the circular arc thrust; At least be provided with 1 hole on the said circular arc thrust; The sheathed said metal clasp of said rotary connector and said aluminium shell junction, said rotary connecting joint is a big shape of little tail, and said rotary connecting joint head passes said rotary connector middle part; Fix with said lamp holder; Said lamp holder edge is provided with groove, and said lamp holder dop is provided with back hook, the sheathed spring in bottom, and said lamp holder dop passes the hole on the said circular arc thrust through said groove with said back hook from the bottom up.

As possibility, said rotary connector also is provided with the block-like protrusions thing, and said metal clasp is provided with breach, and said breach can fasten said block-like protrusions thing.

The beneficial effect of the utility model is: the utility model is through the design of aluminium outer surface of outer cover dentation; Make area of dissipation bigger; The a plurality of apertures that are provided with through circular arc thrust and the cooperation of lamp holder dop at rotary connector; Can adjust the angle of the relative lamp bracket of LED fluorescent lamp, maximum adjustment angle is positive and negative 90 degree; Utilize the directionality of led light source, the range of application of LED fluorescent lamp to remedy the deficiency of lighting angle, has been expanded in the zone of irradiation user appointment.The utility model is because simple in structure, reasonable in design, dependable performance, and effect is remarkable, and accessory can be hyperphoric voluntarily by demand, and global shape is attractive in appearance, is convenient to produce; The rotatability that it has efficiently solves the limitation that the LED fluorescent lamp uses, and therefore is particularly suitable for extensive popularization.
