Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.It should be appreciated that herein Described detailed description of the invention is merely to illustrate and explains the utility model, is not limited to the utility model.

Incorporated by reference to refering to Fig. 1 to Fig. 4, a kind of LED lamp bar 4 shown in the utility model preferred embodiment includes that a hard is long The aluminium base 40 of stripe shape, two faces that on aluminium base, area is bigger are respectively as the front and back of aluminium base, at aluminium base 40 Front on be pasted with copper foil layer 41 and multiple LED chip 42, the end of described aluminium base 40 together with copper foil layer along aluminium base Direction, the back side bends, and the LED lamp bar after bending is applicable to more different light fixture, expands the range of application of LED lamp bar, Also the illuminating effect of LED lamp is improved.

More accurate, in this preferred embodiment, at the back of the body of described aluminium base 40 in order to preferably realize bending and crooked place Face is provided with groove 5, and described aluminium base 40, with groove 5 as axle center, bends to direction, aluminium base 40 back side, does not affects during for bending To LED chip 42, described groove 5 is arranged in the region between adjacent LED chip 42.

In this preferred embodiment, described aluminium base being only provided with a groove 5, described LED lamp bar 4 has only been carried out once Bending, it is contemplated that can also arrange multiple groove 5 on described aluminium base 40, LED lamp bar 4 can realize repeatedly bending.Refer to Fig. 5, the plurality of groove 5 can be arranged between the two adjacent LED chip 42 in same section of region, and LED lamp bar 4 is this two neighbour's Continuous gradation bending is realized, to reach required bending angle and don't meeting because of disposable bending angle between LED chip 42 The copper foil layer 41 that fractures too greatly.Referring to Fig. 6, it is two adjacent that the plurality of groove 5 can also be separately positioned on different section region Between LED chip 42, thus LED lamp bar 4 can realize the bending of discontinuity, to reach different bending demand.

Incorporated by reference to reference to Fig. 7, described groove 5 is set to V-groove, it is also possible to be any in semi-circular groove or grooved groove A kind of；When arranging multiple groove 5 on aluminium base 40, it can be the combination of any one or more in three of the above grooved.

The degree of depth of described groove 5, depending on the thickness of aluminium base 40, should not arrange too deep and the most shallow, otherwise easily snap off Aluminium base 40 or do not have preferably bending effect, groove 5 degree of depth of described setting aluminium base 40 thickness 1/6th to In the range of 3/4ths.

In LED lamp bar 4 bends, the copper foil layer 41 arranged in LED lamp bar 4 can bend, in order to not together with aluminium base 40 The curved disconnected copper foil layer 41 of meeting, described copper foil layer 41 uses the preferable copper foil material of ductility, preferably uses rolled copper foil.It addition, I Can also use the copper foil layer 41 of thickening, the thickness of copper foil layer 41 is arranged between 1.0nm to 5.0nm.

Continuing with combining with reference to Fig. 1 and Fig. 5, described LED lamp bar 4 is additionally provided with phosphor powder layer 43, described fluorescent material Layer 43 can cover in LED chip 42 by continuous print, it is also possible to the covering of interruption is in LED chip.

Incorporated by reference to reference to Fig. 8, Fig. 9, the utility model preferably implements shown a kind of LED lamp, including lamp holder 1 and lamp Head connect housing 2, the U-shaped diffuser 3 being arranged on housing 2, the driving (not shown) being fixed in housing 2 and be placed in Described LED lamp bar 4 in light shield 3, described LED lamp bar 4 electrically connects with driving, drives and electrically connect with lamp holder 1, and described lamp holder 1 leads to Cross and be connected with external power source and power to LED lamp.

Two described LED lamp bar the most at one end bent, the bending of described LED lamp bar 4 are set in the U-shaped diffuser of described list Part is upwards near U-shaped diffuser top, and with the segmental arc mating shapes of U-shaped diffuser, in like manner, double-U-shaped diffuser just sets Putting 4 described LED lamp bar, the LED lamp bar that how U-shaped diffuser needs is the most by that analogy.It is being provided with double-U-shaped diffuser In LED lamp, in order to reduce the dark space of diffuser 3 surrounding, described LED lamp bar 4 is close diffuser in being arranged on the pipe of diffuser 3 On the position of central shaft, and described LED chip 42 outward direction irradiates.

It is contemplated that the described LED lamp holder of multistage bending can be also used in the LED lamp of replacement helical florescent lamp, or Person is used for substituting that flower pattern fluorescent lamp etc. is regular or in irregular LED lamp.

LED lamp bar of the present utility model, after bending, is applicable to more different light fixture, is used for substituting conventional u-shaped glimmering During the LED lamp of light modulation, it is possible to resolve dark space, U-shaped diffuser top problem so that the illuminating effect of light fixture is more preferably.

Without departing from the thought of the invention, the various different embodiments of the present invention are combined, all should When being considered as present disclosure；In the technology concept of the present invention, technical scheme is carried out multiple simple modification And any combination of the thought without prejudice to the invention that different embodiment is carried out, all should protection scope of the present invention it In.
