Abstract
The utility model discloses a reflective LED jacklight which includes a mounting bracket, an arc reflective film connecting the two side ends of the mounting bracket, and a circuit board arranged in the mounting bracket and used for fixing a LED light source; the jacklight is formed by jointing a plurality of independent lighting units. The reflective LED jacklight changes point light source of LED into surface light source to shine so as to have light and thin structure as well as uniform brightness; moreover, modularized jointing mode is suitable for producing large lamps and lanterns and also leading the shapes of the lamps and lanterns to be versatile.
Description
Technical field
The utility model relates to the LED illuminating lamp, further, relates to a kind of reflecting type LED illuminating lamp.
Background technology
With lighting day all general be applied in daily life of LED as light source, but because LED is a kind of spot light, its volume is very little but brightness is very high, so glare problem is very serious.For addressing this problem, the applicant provides a kind of in for 200920078034.7 at application number spot light has been become the reflecting type LED illuminating lamp of area source, efficiently solves the sense of discomfort that this glare problem causes.And it is simple in structure, frivolous.But single, the simple defective of moulding of reflecting type LED lighting existence form of this thin type area source, when it was applied to room lighting, decorative effect was strong inadequately, and was difficult to make large-scale indoor illumination light fitting.
The utility model content
The utility model is for solving the problems of the technologies described above, a kind of reflecting type LED illuminating lamp is provided, and not only the light that the LED spot light is sent changes surface source luminescence into, makes light softer evenly, and the light fixture profile is frivolous, and its moulding can be carried out multiple conversion according to actual needs.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of reflecting type LED illuminating lamp comprises mounting bracket, is connected and installed the arch reflective membrane of support two side ends and is placed on the circuit board that is used for fixing led light source in the mounting bracket, described illuminating lamp be by several independently lighting unit be spliced.
Described lighting unit comprises two tracks that are oppositely arranged.
The track of described adjacent lighting unit is by the splicing of arch brace, and described arch brace is across the two side ends at described mounting bracket.
Splice with predefined angle between the described adjacent lighting unit.
Described track is being provided with one group of slot and one group of depression platform that is used to install described circuit board that is used to install described reflective membrane along corresponding respectively on its length direction.
Away from a side of reflective membrane one baffle plate is set at each led light source, line with the led light source of described support one side lower limb and its opposite side is a reference line, described baffle plate and this reference line form an intersection point, and the height of described baffle plate is not less than the distance between its bottom and this intersection point.
One side of described mounting bracket is placed led light source.
Curved, circular, the S shape of the LED illuminating lamp that described several lighting units are spliced into.
Described mounting bracket is acrylic or aluminium.
The beneficial effect that the utility model brings:
The reflecting type LED illuminating lamp that the utility model provides adopts sliceable formula lighting unit to be spliced, and this modular construction has been simplified production technology, has improved production efficiency, and is convenient to make large-scale lighting.Connect by brace between some lighting units, the two ends of brace are designed to arcuate structure according to actual needs, when the track of adjacent lighting unit is installed in the two ends of this brace, certain angle will be between the track, thereby multiple modeling transformations such as the illuminating lamp that is spliced is curved, circular, S shape can be realized.In the setting of led light source one side shield, make that human eye be can't see led light source in the area to be illuminated territory, prevented the sense of discomfort that dazzle produces.The reflecting type lighting system is converted into the high performance lED spot light thin type area source of high efficiency light-emitting again, and the mounting bracket that adopts acrylic or aluminium to make.Make that luminous evenly structure is frivolous, save material, reduce cost.
In addition, under the situation of equal-wattage, employing is at the one-sided placement led light source of mounting bracket, all placing led light source with bilateral compares, because the mounting distance between the led light source of equal number can be littler, thereby the irradiation dark space that may exist when effectively having avoided between the light source distance big makes that the light in area to be illuminated territory is more even.

The specific embodiment
Below by accompanying drawing the utility model is done further detailed description:
Fig. 1～Fig. 7, the reflecting type LED illuminating lamp of the utility model first embodiment, comprise mounting bracket 3, across at the arch reflective membrane 6 of mounting bracket 3 two side ends, be placed on the circuit board that is used for fixing led light source 12 in the mounting bracket 3.This reflecting type LED illuminating lamp is to be spliced by as shown in Figure 27 lighting units.Each lighting unit includes two tracks that be arranged in parallel 9, and track 9 is along a corresponding respectively group slot 4 and one group of depression platform 5 that described circuit board 2 is installed of being provided with on its length direction; Circuit board 2 is fixedly mounted on the track 9 by installing hole 7.The both sides of reflective membrane 6 are inserted in the described slot 4 fixing respectively.Described led light source 1 is determined by existing illumination software for calculation according to desired illumination of reality and illuminating effect with the relative position of reflective membrane 6 and the radian that reflective membrane 6 is curved, as dialux (Supreme Being Er Lesi) software (a kind of lighting field that is applied to, but accurate Calculation is also simulated the design software of illuminating effect), perhaps as other software for calculation such as Agi32, Light Star, Lumen micro, Autolux, Inspire.Then by adjusting the distance between the track or realizing the requirement of this radian size by the width of selecting reflective membrane 6.Away from a side of reflective membrane 6 baffle plate 8 is set at led light source 1.Line 100 with the led light source 1 of track 9 lower limbs and its opposite side is a reference line, and described baffle plate 8 forms an intersection point a with this reference line, and the height of described baffle plate 8 is not less than the distance h between its bottom and this intersection point a.Make thus and in illuminating lamp area to be illuminated territory, can't see led light source fully, unlikely generation dazzle.
Be to be stitched together by arch brace 10 between each lighting unit in the present embodiment, this brace 10 is reinforced mounting bracket 3 across the both sides that are installed in mounting bracket 3.Two terminations 101 of brace 10 preestablish into certain radian according to the requirement to the light fixture shape, when the track 9 of adjacent lighting unit is fixedly mounted on two terminations 101 of brace 10 by screw hole 102, just formed certain included angle between the adjacent lighting unit.Realize that so the illuminating lamp that is spliced can take on a different shape.Circle as shown in Figure 8 and S shape shown in Figure 9.
