The specific embodiment
Be that example combines accompanying drawing that light fixture of the present invention and lamp socket thereof are explained further details with high ceiling fitting below.
As shown in Figure 1, according to one embodiment of present invention, light fixture mainly comprises lamp socket 1, lamp socket cavity 2, reflector 3, bulb 4 and cavity lid 5.Wherein, lamp socket 1 is fixed in the lamp socket cavity 2 separably, and reflector 3 is fixed on the lower end of lamp socket cavity 2, and cavity lid 5 is fastened on lamp socket cavity 2 upper ends.Be formed with a plurality of height different fixed faces on the lamp socket 1, bulb 4 can be through being fixed on any one stationary plane.
Please be simultaneously referring to Fig. 2 to Fig. 3, the lamp base of bulb 4 is through first fixture, and for example the screw fit nut is fixed on the middle part of a rectangle sheet lamp socket support 6.The two ends of lamp socket support 6 are fixed on the lamp socket 1 like screw through second fixture.This moment, bulb was positioned on the optical axis of reflector 3.
Please be simultaneously referring to Fig. 4 to Fig. 6, protruding bottle cap is arranged at the similar top of the profile of lamp socket 1, and it comprises that one is the substrate of annular substantially, and the surface towards bulb of this substrate is first stationary plane 11.Be formed with two concave stations 12 symmetrically near the inner edges place on first stationary plane 11.The surface of concave station 12 is basically parallel to first stationary plane 11, forms second stationary plane (also being labeled as 12 here).On first stationary plane 11 also symmetrically projection two fixed legs 13 that are basically perpendicular to first stationary plane 11 are arranged.The top end face of two fixed legs 13 flushes, and forms the 3rd stationary plane (being called for short the 3rd stationary plane) of lamp socket 1.All be formed with a fixing hole on the top end face of each fixed leg 13.Also be formed with symmetrically on first stationary plane 11 on two fixing holes, 111, the second stationary planes 12 and be formed with two fixing holes 121 symmetrically.And, on the circumference that it is the center of circle that the center of above-mentioned all fixing holes all is arranged in the center of circle with first stationary plane 11 (seeing shown in Fig. 4 dotted line).So, when bulb 4 was fixed on the different fixed face through lamp socket support 6, bulb 4 was the diverse locations that are positioned at the optical axis of reflector 3, can realize wide, in, narrow three kinds of luminous intensity distributions.
The outward flange of first stationary plane 11 also upwards vertically extends an annular sidewall 15.Be formed with a plurality of (in the present embodiment being 3) on the sidewall 15 and be rotational symmetric arc notch (bayonet socket), thereby make the part of sidewall 15 be hook-shaped, form hook portion 151.
Preferably, lamp socket 1 is formed in one and processes, and material can be plastic cement, metal or alloy.In the present embodiment, lamp socket 1 adopts pack alloy, makes lamp socket under the prerequisite of proof strength, have lighter weight.
Please consult Fig. 1 and Fig. 7 simultaneously, the top of reflector 3 is formed with the lamp hole that supplies bulb 4 to pass, and the edge that forms this lamp hole is fixed on the lower end of lamp socket cavity 2.The structure of lamp socket cavity 2 is similar to a double-deck fixed cover, is formed with the lamp socket host cavity 21 that communicates with this lamp hole on it.Be formed with a plurality of projections 211 that cooperate with the hook portion 151 of lamp socket 1 symmetrically on the inwall of this lamp socket host cavity 21 of formation on the lamp socket cavity 2.Lamp socket 1 revolves card connection with lamp socket cavity 2 through projection 211 and hook portion 151 separably is in the same place.Preferably, the plastic parts that is formed in one of lamp socket cavity 2.
The top of lamp socket cavity 2 is formed with the opening that communicates with lamp socket host cavity 21, and lamp socket 1 can pass this opening with bulb 4.Cavity lid 5 is fastened on the lamp socket cavity 2 separably.In the present embodiment; As shown in Figure 1; One end of cavity lid 5 is rotatably connected to through a bearing pin fixed structure 7 one side with lamp socket cavity 2 tops, and the other end of cavity lid 5 links together through the another side on a hasp 8 (see figure 8)s and lamp socket cavity 2 tops separably.
During assembling; Be fixed on bulb 4 on the stationary plane wherein of lamp socket 1 through lamp socket support 6 according to predetermined luminous intensity distribution demand earlier; Reflector 3 and cavity lid 5 are fixed on the lamp socket cavity 2; The lamp socket 1 that will be fixed with bulb 4 then inserts in the lamp socket host cavity 21 of lamp socket cavity 2, and bulb 4 is stretched in the reflector 3 from lamp socket host cavity 21, and the arc notch on projection 211 insertion lamp sockets 11 sidewalls 15.Rotary lampholder 11 then, make projection 211 get into the bottom of arc notch, make lamp socket 1 and 2 lockings of lamp socket cavity.At last, cover cavity lid 5, lock hasp, accomplish assembling.
Need more change the bulb or when changing the luminous intensity distribution of light fixture, as long as open cavity lid 5, rotary lampholder 1 can take off lamp socket 1 and bulb from lamp socket cavity 2.The fixed pan that takes off bulb or change bulb from lamp socket support 6 then gets final product.
Understandable, in other embodiments, can at the concave station and the fixed leg that are provided with on the lamp socket more than three or three, simultaneously, the fixing hole more than three or three be set accordingly on each fixed pan according to the shape of lamp socket support.Among other embodiment, can concave station or fixed leg be set on the lamp socket, only surplus two fixed pans according to demand.Among other embodiment, the connected mode of lamp socket and lamp socket cavity can adopt the separable connected mode of existing other types, for example buckle type syndeton.Also can adopt the separable syndeton of rotary clamp type between lamp socket cavity and the cavity lid.
To sum up; Be formed with a plurality of height different fixed faces on the lamp socket of light fixture of the present invention; Through bulb is fixed on the different fixed face, make bulb be positioned at the diverse location on the optical axis of light fixture, thereby under the prerequisite of same reflector; Realize different luminous intensity distribution demands, have simple in structure, design advantage cleverly.Lamp socket will be fixed on the lamp socket cavity through the rotary clamp type structure, thereby lamp socket and lamp socket cavity have independence, and will be quick detachable.Adopt the buckle type syndeton to connect cavity lid and lamp socket cavity, make light fixture keep whole outward appearance, the installation procedure that makes light fixture simultaneously advantages of simple maintenance more is more prone to quick.
The above embodiment has only expressed several kinds of embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction of claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, can also make some improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with appended claims.
