The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further description.
Like Fig. 2～Fig. 6 and shown in Figure 13, the described LED lighting device of the utility model comprises luminescence unit 10 and reflector 20 with led light source 11.Reflector 20 has plane reflecting surface 20R.Luminescence unit 10 also comprises at least one light-emitting area, and said light-emitting area is the light-emitting area 11L of plane or curved led light source 11 bodies.One side of the reflecting surface 20R of reflector 20 near or be attached on the light-emitting area 11L of luminescence unit 10, the section, center of light-emitting area 11L and the angle of reflecting surface 20R are 90 °～130 °, preferred value is 90 °.Led light source 11 bodies are packaged LED element or the modules that have chip; In the luminescence unit several LED elements can be set; Because of the paster LED element has light-emitting area is the curved surfaces such as also promising sphere on plane, and this has just explained why luminescence unit comprises that at least one light-emitting area and said light-emitting area are plane or the curved surface shape.
Like Fig. 2～shown in Figure 12; The outer surface that said light-emitting area that different with top described embodiment is is mounted in the light source cover 12 on the led light source 11 is as light-emitting area 12L; The section, center of light-emitting area 12L and the angle of reflecting surface 20R are 90 °～130 °, and preferred value is 90 °.
Since one side of the reflecting surface 20R of reflector 20 near or be attached on the light-emitting area 11L or 12L of luminescence unit 10; And the angle of light-emitting area 11L or section, 12L center and reflecting surface 20R is 90 °; Show ejaculation and light-emitting area 11L or the equal-sized image of 12L at the reflecting surface 20R of reflector 20; Just as we look in the mirror, therefore, light-emitting area and reflecting surface have constituted the mirror reflection key element; We have these two key elements and each other angle be that 90 °～130 ° and preferred 90 ° of these principles of reflection call mirror reflection, adopt the reflector of this principle of reflection to be called the mirror reflection device.
As shown in Figure 2; In effective range of exposures; All can accumulate in M point and N point on the shadow surface from a branch of direct light BL of led light source with from a branch of mirror reflection light BR of primary reflection surface; This just is similar to a point has two light source irradiation, has greatly improved the brightness value of shadow surface, has saved the energy effectively.
Based on the difference at the different luminous angles of led light source, though according to the principle of mirror image, it is preferred value that the angle of two key elements equals 90 °; In specific structure as light-emitting area be the curved surface shape and with respect to below light source the zone illumination; Angle also can be a bit larger tham 90 °, but should not surpass 130 °, otherwise mirror image projection scope is big more; Effectively the illumination of shadow surface is low more, and this is vital.
Shown in figure 11, the section, center of the light-emitting area 11L of diffuser 12 inner mounted LEDs light sources 11 is 90 °～130 ° with the angle of the interior reflective surface 20R1 of the reflector 20 that is installed in diffuser 12 inside, and preferred value is 90 °.This shows; Embodiment shown in Figure 11 diffuser 12 inside have light-emitting area 11L and the reflecting surface 20R1 of led light source body constitute in mirror image reflect key element; There are light-emitting area 12L and the reflecting surface 20R of diffuser 12 to constitute outer mirror image in diffuser 12 outsides and reflect key element; Therefore, this is an embodiment with dual mirror reflection effect.In the present embodiment, reflecting surface 20R1 has adopted principal reflection plate 21 in the inner part of diffuser 12, also can adopt independently reflecting plate as the reflecting surface of inside, to be fit to the Different products demand.Reduce light loss in order further to improve light efficiency, a little reflecting plate 15 is set, be used for reflecting this part light, also can make the light on light-emitting area 12L surface more even in the opposite side side that just 20R1 is relative of led light source 11.
Shown in Figure 13 and 14; In reflector body 22 inside reflecting plate 21 is installed; Led light source installation base plate 13 is installed in the die cavity of afterbody, led light source 11 is installed on led light source installation base plate 13, the section, center of the light-emitting area 11L of led light source 11 is 90 °～130 ° with the angle of the interior reflective surface 20R1 of the reflector 20 that is installed in diffuser 12 inside; Preferred value is 90 °; Led light source 11 both sides have boosting reflector 30R in die cavity, are coated with diffuser 23 in the die cavity outside, and fixing by frame 24.This shows that this is an embodiment with interior mirror image reflection key element.Diffuser 23 can be plane, also can be the curved surface shape.
Like Fig. 4 and shown in Figure 6; In order further to reduce the loss of reflector 20 both sides light; Improve the utilization rate of LED light on effective shadow surface, also can be provided with two auxiliary reflectors 30 in the both sides of reflector 20, said auxiliary reflector has plane reflecting surface 30R; One side of its reflecting surface 30R near or be attached on the light- emitting area 11L or 12L of luminescence unit 10, one side on the adjacent reflecting surface 20R that is attached to main reflector 20.
The reflecting surface 20R of reflector 20 is coating film on glass or plastics plated film or metal coating or medal polish.
The reflecting surface 30R of auxiliary reflector 30 is coating film on glass or plastics plated film or metal coating or medal polish.
The reflecting surface 20R of reflector 20 is the minute surface or the cloudy surface of high reflectance.
The reflecting surface 30R of auxiliary reflector 30 is the minute surface or the cloudy surface of high reflectance.
[0039] like Fig. 7, Fig. 9 and shown in Figure 11; The independently radiator 14 that the led light source 11 of the utility model can have; Also can be shown in figure 13 be the one thermolysis of having held concurrently altogether with reflector body 22; Reflector body can adopt like metal materials such as aluminium alloy, aluminium sheets according to actual needs, also can adopt plastics such as PC or ABS.
Figure 15 and Figure 16 are respectively that the utility model is applied in the illumination effect sketch map on desk lamp and the street lamp; Describe and according to our experiment according to above-mentioned each embodiment; Can effectively solve the low problem of sparing and being easy to generate dazzle of existing LED lighting device illumination on needed shadow surface with uneven illumination; Improve the illumination of LED lighting device on shadow surface, made the illumination of shadow surface more even, and can effectively prevent the generation of dazzle; Can reduce the input power of LED under the same illumination, save the energy.
