The specific embodiment

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.

Embodiment 1

As shown in Figure 1, the LED bar lamp of this high uniform illumination, comprise the pedestal 5 of being made by aluminium section bar, 2 laterally connect successively and arrange the draw-in groove 6 that is the arch that protrudes from pedestal on pedestal, the aluminium base 4 that corresponding each draw-in groove is installed, on each aluminium base, install and arrange 20 elongated LED lamp pearls 3, and being arranged in pedestal and the driving power 1 being all electrically connected to each aluminium base.Specifically, the base plane at draw-in groove and its place is 50 ° with upper angle, and all draw-in grooves axial symmetry and distribution equal in number centered by the vertical line of this base plane.For LED lamp pearl is prevented dust, anti-aging and expand light needs, on pedestal, be also provided with for cover all LED lamp pearls and with the detachable lampshade being connected 2 of pedestal, easy disassembly and replacing, specifically, this detachable connection employing clamping form.

Illustrate the position that draw-in groove and aluminium base arrange below: selecting a face of aluminium section bar pedestal is datum level, pedestal upper plane as shown in Figure 1, the center vertical line of this plane of take is axle, two draw-in grooves are symmetrical, the one end of the two is all fixedly connected with pedestal, the other end is mutually permanently connected, horizontal vertical section (being the face shown in Fig. 1) from bar lamp integral body, two draw-in grooves and datum level have formed an isosceles triangle jointly, and the acute angle angle of two draw-in grooves and datum level is greater than 50 °, and the bottom surface that aluminium base is parallel to draw-in groove is installed in draw-in groove.Guaranteed that thus the utility model can wide-angle and the using of high uniform illumination.

Embodiment 2

As shown in Figure 2, the difference of the present embodiment and embodiment 1 is, the quantity of described draw-in groove is 4, and the quantity of aluminium base is also 4.The concrete arrangement mode of draw-in groove is similar to Example 1, specific as follows: on the section shown in Fig. 2, draw-in groove connects from left to right successively, the left end that is first draw-in groove is connected with pedestal, the right-hand member of first draw-in groove is connected with the left end of second draw-in groove, by that analogy, the left end of the 4th draw-in groove is connected with the right-hand member of the 3rd draw-in groove, and the right-hand member of the 4th draw-in groove is connected with pedestal.And it is axial symmetry that first draw-in groove and the 4th draw-in groove be take the center vertical line of datum level, it is axial symmetry that second draw-in groove and the 3rd draw-in groove be take the center vertical line of datum level.Four draw-in grooves and datum level be common to be formed one and take above-mentioned center vertical line as axisymmetric pentagon, and the acute angle angle of four draw-in grooves and datum level is greater than 50 °.Make to be thus arranged on aluminium base in draw-in groove towards different larger angles, and the range of exposures of LED lamp pearl on each aluminium base is 120 °, adjacent range of exposures is overlapped, not only makes to irradiate evenly, and intensity of illumination is large, thereby realize the good result of high uniform illumination.Through test, its illumination even intensity degree on same curved surface is greater than 0.4, has compared greatly improve with common LED bar lamp.

Embodiment 3

As shown in Figure 3, the difference of the present embodiment and embodiment 1 is, the quantity of described draw-in groove is 6, and the quantity of aluminium base is also 6.The concrete arrangement mode of draw-in groove is similar to Example 1, specific as follows: on the section shown in Fig. 3, draw-in groove connects from left to right successively, the left end that is first draw-in groove is connected with pedestal, the right-hand member of first draw-in groove is connected with the left end of second draw-in groove, by that analogy, the left end of the 6th draw-in groove is connected with the right-hand member of the 5th draw-in groove, and the right-hand member of the 6th draw-in groove is connected with pedestal.And it is axial symmetry that first draw-in groove and the 6th draw-in groove be take the center vertical line of datum level, it is axial symmetry that second draw-in groove and the 5th draw-in groove be take the center vertical line of datum level, and it is axial symmetry that the 3rd draw-in groove and the 4th draw-in groove be take the center vertical line of datum level.Six draw-in grooves and datum level be common to be formed one and take above-mentioned center vertical line as axisymmetric heptagon, and the acute angle angle of 6 draw-in grooves and datum level is greater than 50 °.Through test, its illumination even intensity degree on same curved surface is also greater than 0.4, not only compared with common LED bar lamp greatly and to have improved, and it is larger to compare the intensity of illumination uniformity of the first two embodiment.

But the draw-in groove arranging and the quantity of aluminium base are more, and the cost of manufacturing is higher, and after having carried out the contrast of production cost and the illumination uniformity, shown in embodiment 2 and embodiment 3, the cost performance of structure is the highest.

According to above-described embodiment, just can well realize the utility model.What deserves to be explained is; under prerequisite for said structure design; for solving same technical problem; even if some that make on the utility model are without substantial change or polishing; the essence of the technical scheme adopting is still consistent with the utility model, also should be in protection domain of the present utility model.
