Description of drawings
To combine accompanying drawing and embodiment that the present invention is described further below, in the accompanying drawing:
Fig. 1 is the dustproof fitting structure cutaway view of preferred embodiment of the present invention;
Fig. 2 is the dustproof light fixture sectional perspective structural representation of preferred embodiment of the present invention;
Fig. 3 is an A part enlarged diagram among Fig. 2;
Fig. 4 is a light source assembly structural representation in the dustproof light fixture of preferred embodiment of the present invention.
The specific embodiment
The dustproof fitting structure of the embodiment of the invention is as shown in Figure 1, and it comprises housing 10, and is arranged on and is used in the housing 10 to realize the light source assembly 20 that throws light on also comprise the diffuser 30 that is arranged on housing 10 opening parts, is used to appear light.Wherein, be provided with the protecting film 40 of one deck light-permeable at diffuser 30 outer surfaces, protecting film 40 edges are dismountable is connected on the housing 10 for this.As shown in Figures 2 and 3, in order further to guarantee the seal between translucent cover 30 and the housing 10, on housing 10 madial walls, also be provided with the anticreep head part 17 that is used for applying outward pressure to diffuser 30.Like this, protecting film 40 neither can have influence on the translucent effect of diffuser 30, can also prevent that dust from directly overlaying diffuser 30 outer surfaces simultaneously, protection diffuser 30.
Because protecting film 40 is to adopt the mode of removably connecting to be connected on the lamp housing 10; The attendant can be regularly takes off the protecting film 40 that wears out or cover too much dust from housing 10; The protecting film 40 that more renews can keep the illuminating effect of light fixture so for a long time, and change easily.
In the foregoing description, anticreep head part 17 can be the arbitrary structures that can play aforementioned effect.Preferably, adopt " several " font structure shown in Fig. 2 and Fig. 3, its dual-side is connected on the housing 10 madial wall both sides, and the upper surface of intermediate projections part contacts with diffuser 30 inner surfaces, to apply outward pressure to diffuser 30.After translucent cover 30 is installed in housing 10 opening parts; 17 pairs of translucent covers 30 of this anticreep head part apply outside pressure; Translucent cover 30 further is pressed in the installation draw-in groove 13, makes that seal is better between translucent cover 30 and the housing 10, prevent that dust from entering into lamp interior.
In further embodiment, as shown in Figure 1, the outer side edges of housing 10 opening parts of above-mentioned dustproof light fixture is along being provided with indent 11, and the edge of protecting film 40 is fitted on the housing 10 through elastic layerings 12 sealings that are interference fitted in the indent 10.That is, adopt elastic layering 12 that the edge of protecting film 40 is pressed in the indent 11, prevent that it from will coming off from translucent cover 30.This fixed form is simple in structure, and dismounting is very convenient, can also realize being tightly connected between protecting film 40 and the housing 10 simultaneously, prevents that dust or greasy dirt from entering on the diffuser.
In the foregoing description, as shown in Figure 1, indent 11 cross sections preferably adopt wedge shape, and press strip 12 cross sections and indent 11 shape of cross sections are suitable, so that be advisable in elastic layering 12 ability interference fit such as the indent 11.It will be understood by those skilled in the art that except adopting this mode that removably connects, can also adopt other modes that removably connect that protecting film 40 is fixed on the housing 10.
In a further embodiment, as shown in Figure 1, along being provided with draw-in groove 13 is installed at housing 10 opening part inner side edges, the edge of translucent cover 30 is fastened on to be installed in the draw-in groove 13, and between the gap of translucent cover 30 edges and installation draw-in groove 13, is provided with seal washer 14.Like this can be with preventing that the junction between translucent cover 30 and the housing 10 from getting into dust or steam, further plays the dustproof effect.
Among above-mentioned each embodiment, the housing 10 of dustproof light fixture can be an arbitrary shape, like cylindrical shape, taper etc., also can be strip relatively more commonly used at present.
As shown in Figure 2, when the housing 10 of dustproof light fixture is strip, the end cap 15 that it comprises the U-lag body 16 of bar shaped and is arranged on 16 liang of openends of U-lag body.As shown in Figure 3, anticreep head part 17 is connected between the two sides of U-lag body 16, and upwards withstands translucent cover 30 inner surfaces, translucent cover 30 further is pressed on installs in the draw-in groove 13, makes that seal is better between translucent cover 30 and the housing 10.
Among above-mentioned each embodiment, protecting film 40 can fit with diffuser 30 outer surfaces, also can leave the gap.When protecting film 40 and diffuser 30 outer surfaces fit, preferably adopt Heat stability is good, light aging resisting, can printing opacity, thin-film material that coating performance is good.
Among above-mentioned each embodiment, like Fig. 1 and shown in Figure 4, light source assembly 20 comprises reflector 21 and the illuminator 23 that is arranged in the reflector 21.Be provided with mounting ear 22 at reflector 21 outer surfaces, mounting ear 22 is provided with installing hole 221, and reflector 21 is fixed on housing 10 inside through the screw that is arranged in the installing hole 221.It is more firm that reflector 21 is installed, and play antihunt action.
The present invention is provided with dismountable protecting film 40 through diffuser 30 outer surfaces at light fixture, plays the dustproof effect to diffuser 30.For being in outdoor light fixture for a long time; Because the influence of natural causes such as weathering, protecting film 40 is easy to wear out, thereby influences illuminating effect; Therefore be set to protecting film 40 dismountable; Be convenient to the protecting film 40 that more renews more, make it continue to play the dustproof effect, make the lamp lighting better effects if.
Should be understood that, concerning those of ordinary skills, can improve or conversion, and all these improvement and conversion all should belong to the protection domain of accompanying claims of the present invention according to above-mentioned explanation.
