Preferably, said lampshade side flanging is provided with claw, and base side flanging corresponding position is provided with the draw-in groove that is interlocked with said claw.
Further again, described LGP matches is arranged in the groove that base and base side flanging surrounded.
The back side of described LGP has posted one deck reflective membrane.
Further again, LGP one side that the LED lamp substrate is installed also is provided with boundary frame area, and the tow sides of LGP are clipped between two limits of boundary frame area, and the LED lamp substrate is positioned at the frame of boundary frame area.
Preferably, described boundary frame area is a metal frame.
For the light with the LED lamp reflects back in the LGP, prevent that lamp energy dissipation and top light are too bright, a side relative with the LED lamp substrate on said LGP posts reflector plate.
Preferably, said LGP is a transparent panel.
Preferably, described lampshade is a translucent mask, when the light that penetrates passes through lampshade, can play even light effect.
For being uniformly distributed with of light, on the surface of said LGP, print, carve, perhaps be pasted with the pip of non-uniform Distribution.
Compared with prior art; The advantage and the good effect of the utility model are: the lighting device of the utility model, and only the side at LGP is provided with the LED lamp, provides cost savings; A side relative with the LED lamp substrate on LGP posts reflector plate, has reached the effect that two groups of LED lamps are set; Through lampshade and base are set; Not only can play the effect of protection LED lamp and LGP, and lampshade can play even light action, even light film need not be set in the LGP front specially; Base can play reflex; Need not reflector plate be set at the back side of LGP, lampshade adopts translucent mask, and even light effect is better.
After the detailed description in conjunction with advantages the utility model embodiment, other characteristics of the utility model and advantage will become clearer.
Description of drawings
Fig. 1 is a kind of example structure sketch map of lighting device that the utility model proposes;
Fig. 2 is the right view of LGP 2 among Fig. 1;
Fig. 3 is the partial enlarged drawing of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the utility model is done explanation in further detail.
Embodiment one, referring to shown in Figure 1, and the lighting device of present embodiment; Comprise lampshade 1, LGP 2 and base 3 that one is installed, said LGP 2 is installed between lampshade 1 and the base 3, referring to shown in Figure 2; Be the right view of LGP 2,, be the partial enlarged drawing of Fig. 2 referring to shown in Figure 3; Can see that from Fig. 3 a side of LGP 2 is equipped with LED lamp substrate 4, be fixed with LED lamp 5 on the said LED lamp substrate 4.Wherein, LED lamp substrate 4 can be installed in arbitrary side of LGP 2.
In order to play good light guide effect, said LGP 2 is a transparent panel, can adopt the good materials of transparent effect such as acrylic, PCR.The described lampshade 1 preferred translucent mask that adopts when the light that penetrates during through lampshade, can play even light effect, and even light film need not be set in the LGP front specially.
As a concrete embodiment, lampshade 1 with the structure of base 3 installations is in the present embodiment: said 3 one weeks of base are provided with base side flanging 6, and said lampshade 1 correspondence is provided with the lampshade side flanging 7 that is interlocked with base side flanging 6.Fasten mounting stability in order to increase both, preferably said lampshade side flanging 7 is provided with claw 71, and base side flanging 6 corresponding positions are provided with the draw-in groove 61 that is interlocked with said claw 71.Certainly, also can adopt other frame modes to fix,, adopt that screw is fixed etc. such as on lampshade side flanging 7, through hole being set respectively with base side flanging 6 corresponding positions.
Need to prove that the inner surface of base 3 and base side flanging 6 all has reflection action, generally need reflector plate be set specially, realized the effect of reflector plate equally, further reduce cost at the back side of LGP and the side of non-LED lamp direct projection.Certainly, at some in particular cases, when very near, can paste one deck reflective membrane through the back side, to improve reflecting effect at LGP 2 apart from base 3 such as LGP 2.
LGP 2 can be fixed between the two when lampshade 1 and base 3 are interlocked; Preferably described LGP 2 is arranged in the groove that base 3 and base side flanging 6 surrounded together with what LED lamp substrate 4 matched; It is fixing with LGP 2 that claw can also be set in the inboard of base side flanging 6; Perhaps perforation on LGP 2 uses screw to be fixed on the base 2, reaches firm effect.
Referring to shown in Figure 3; For LED lamp substrate 4 and LGP 2 are fixed; Also be provided with boundary frame area 8 at the LGP that LED lamp substrate 4 is installed one side, the tow sides of LGP 2 are clipped between two limits of boundary frame area 8, and LED lamp substrate 4 is positioned at the frame of boundary frame area 8.The described boundary frame area 8 preferred metal frames that adopt so not only can play good fixed effect, and can play good thermolysis, help prolonging the service life of LED lamp.
For the light that prevents 5 direct projections of the LED lamp other end face from LGP 2 penetrates; And cause energy dissipation and top light too bright; Preferably on said LGP 2, post reflector plate 9,, so not only can prevent energy waste so that the light of LED lamp is reflected back in the LGP 2 with LED lamp substrate 4 relative sides; And the light of reflector plate reflection can reach the effect that one group of LED lamp is set, and reduced cost when increasing lighting effect.
For being uniformly distributed with of light, on the surface of said LGP 2, print, carve, perhaps be pasted with the pip of non-uniform Distribution.The non-homogeneous layout of pip is because more intense near the position light intensity of LED lamp 5 and reflector plate; Can with pip be provided with more sparse; Accordingly, from LED lamp 5 and reflector plate position beam intensity ratio far away a little less than, can with pip be provided with denser; Thereby better light is uniformly distributed with, obtains the large tracts of land uniform area light source.
The lighting device of present embodiment, only the side at LGP is provided with the LED lamp, provides cost savings, and a side relative with the LED lamp substrate on LGP posts reflector plate, has reached the effect that two groups of LED lamps are set; Through lampshade and base are set; Not only can play the effect of protection LED lamp and LGP, and lampshade can play even light action, even light film need not be set in the LGP front specially; Base can play reflex; Need not reflector plate be set specially at the back side of LGP, lampshade adopts translucent mask, and even light effect is better.This device can be applied in the refrigerator, for throwing light in the refrigerator inside space, certainly, also can be applied on other electric equipments and throw light on, and perhaps the backlight screen as advertisement cabinet uses.
Certainly; Above-mentioned explanation is not to be the restriction to the utility model; The utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that those skilled in the art are made in the essential scope of the utility model also should belong to the protection domain of the utility model.
