For solving the problems of the technologies described above, the present invention proposes a kind of reflective mirror of light fixture, comprise: an inner surface is the reflector of minute surface, described reflector is the bowl-shape of top end opening, the bottom of described reflector is provided with one in order to the installing hole of light source to be installed, be provided with the fin of some inwardly protruded strips on the inwall of described reflector, described fin distributes centered by the installing hole of described reflector radially.
Preferably, described reflector is the paraboloid of revolution, and described fin distributes along the bus of the described paraboloid of revolution.
Preferably, described reflector by the top to bottom convergent bore, described fin is scattered in up and down two zones at the inwall of described reflector, the positions that have a common boundary in two zones up and down form a horizontal line of demarcation, each fin in the upper zone extends to the top of described reflector always by described horizontal line of demarcation, each fin in the lower area extends to described installing hole edge by described horizontal line of demarcation always.
Preferably, the spacing between the adjacent fin in each zone equates.
Preferably, the cross section of described fin roughly is in the shape of the letter V.
Preferably, described fin comprises the both sides of the chest arm that an end links to each other, and the angle between described both sides of the chest arm is between 120 degree are spent to 150.
Preferably, described both sides of the chest arm is circular arc chamfering at the angle of link position.
Preferably, described reflective mirror is made by aluminium sheet.
Preferably, described fin passes through mould pressing.
Preferably, described reflective mirror also comprises the light source mount pad of the position of mounting hole that is arranged on described reflector.
Compared with prior art, beneficial effect of the present invention comprises: the present invention arranges the angle of reflection that fin comes increasing light by the inner surface at reflector, the light emitting anger of light fixture is increased, realize floodlighting, because the inner surface of reflector is not processed through frosted, still be minute surface simultaneously, so light reflectance does not become, Luminaire efficiency does not reduce, and has improved the defective of floodlighting meeting reduction Luminaire efficiency in the prior art.

The specific embodiment
In order to further specify principle of the present invention and structure, existing by reference to the accompanying drawings to a preferred embodiment of the present invention will be described in detail.
Consult Fig. 1, light fixture reflective mirror of the present invention comprises: an inner surface be the reflector 1 of minute surface and be located at reflector 1 bottom in order to the light source mount pad 2 of light source to be installed.Reflector 1 is the bowl-shape of top end opening, and its bottom is provided with an installing hole 12, and installing hole 12 connects mount pad 2, passes and is installed in wherein for light source.Be provided with the fin 13 of some inwardly protruded strips on the inwall of reflector 1, fin 13 distributes centered by the installing hole 12 of reflector 1 radially, thereby light is penetrated in the convex rib proportion by subtraction does not have the angle of reflection of the part of fin to increase, so increased the light emitting anger of light fixture, realized floodlighting.
The present invention preferably makes reflector 1 be the paraboloid of revolution, each fin 13 is distributed along the bus of the paraboloid of revolution, thereby obtain better Architecture Floodlighting.
Because reflector 1 is the paraboloid of revolution, thus reflector 1 by the top to bottom convergent bore.The surface area that is to say reflector 1 first inwall is larger, the surface area of second inwall is less, if fin 13 is extended to the aperture position on reflector 1 top by installing hole 12 positions along paraboloidal bus always, can shine into fin 13 comparatively denses of second inwall of reflector, and the fin 13 of first inwall is more sparse, will cause like this floodlight inhomogeneous, also cause the floodlight DeGrain of first reflector 1 simultaneously.For improving this defective, can between adjacent two fins 13 of first inwall, increase by one or two fins 13, and the fin 13 of increase is also distributed along the bus of the paraboloid of revolution, so not only can make the floodlight of first inwall and second inwall even, and increase the whole floodlight effect of reflector.
Certainly, also can make fin 13 be divided into upper and lower two parts distribution along the inwall of reflector, the present embodiment namely adopts this kind mode, in conjunction with consulting Fig. 1 and Fig. 2, fin 13 is scattered in upper and lower two zones at the inwall of reflector 1, the position that has a common boundary in upper and lower two zones forms a horizontal line of demarcation, and each fin 13 in the upper zone extends to the top of reflector 1 always by horizontal line of demarcation, and each fin 13 in the lower area extends to installing hole 12 edges by horizontal line of demarcation always.Fin 13 in each zone preferably evenly distributes in the one's respective area, and the spacing of 13 of adjacent fins in each zone equates.
Consult Fig. 3, Fig. 4, Fig. 5, the cross section of fin 13 roughly is in the shape of the letter V, and it comprises the both sides of the chest arm 131,132 that an end links to each other, and between 150 degree, preferred 135 spend the angle α between the both sides of the chest arm at 120 degree.Both sides of the chest arm 131,132 angles at link position are circular arc chamfering, so that both sides of the chest arm 131,132 more level and smooth in the junction, thereby make light more even, soft at the floodlight of this position.
Reflective mirror in the present embodiment is made by thin aluminum sheet, and the fin 13 of its inner surface is by the aluminium sheet mould pressing, so accordingly, the outer surface of reflector 1 is formed with rectangular groove 14 structures (as shown in Figure 2) corresponding with each fin 13.Obviously, if reflective mirror is selected other thicker materials, it also can adopt mould-injection process to protrude moulding fin 13 in the inner face one of reflective mirror, and at this moment, the reflective mirror outer surface then is smooth flat.
It is worth mentioning that, in other embodiments, reflective mirror of the present invention also can remove light source mount pad 2, only keeps a reflector 1, utilizes outside fixed structure that light source is installed.
Fig. 6 is the distribution curve flux figure of above-mentioned mirror application on the halogen light modulation of E40 lamp holder, and through measuring and calculating, the average intensity angle of reflective mirror reaches 69.9 degree, realized floodlighting, the luminous flux of actual measurement light source is 13000lm, and light fixture emergent light flux is 12042 lm, and Luminaire efficiency is 72.7%.
In sum, the present invention arranges the angle of reflection that fin comes increasing light by the inner surface at reflector, the light emitting anger of light fixture is increased, realize floodlighting, simultaneously because the process frosted processing of the inner surface of reflector, still be minute surface, so light reflectance does not become, Luminaire efficiency does not reduce.
The above only is better possible embodiments of the present invention, and unrestricted protection scope of the present invention, and the equivalent structure that all utilizations specification of the present invention and accompanying drawing content have been done changes, and all is included in protection scope of the present invention.
