Abstract
The invention relates to a mining explosion-proof floodlight which comprises a lower shell, an upper shell and a light source, wherein the upper shell is connected with the lower shell, a light source cavity is formed between the upper shell and the lower shell, the upper shell comprises light-passing boards and a light-blocking beam positioned between the light-passing boards; and the light source is arranged in the light source cavity, and the light-blocking beam is positioned in front of the light source and forms a shadow region on a plane of illumination. The mining explosion-proof floodlight also comprises a reflection part arranged in the light source cavity, wherein the reflection part faces towards the light-blocking beam, reflects out light rays emitted by the light source from the light-passing board at the same side and forms a reflected illumination region covering the shadow region on the plane of illumination. Because of the use of the reflection part, light rays are projected to the shadow region, and simultaneously, the projected light rays can face towards different directions due to the presence of diffuse reflection, so that the emergent light rays are dispersive and uniform, thereby eliminating the shadow generated by the light-blocking beam.

The specific embodiment
As shown in Figure 1, in the first embodiment of the present invention, floodlight of explosion-suppressing type for mine 100 comprises housing, and this housing comprises interconnective upper casing 101 and lower casing 102.The light source fixed support 104 that wherein is provided with electric component 103 in the lower casing 102 and is electrically connected with electric component 103.On light source fixed support 104, be connected with light source 115, this light source 115 is between upper casing 101 and lower casing 102 in the formed light-source chamber 109.
The cross section of floodlight of explosion-suppressing type for mine 100 is roughly triangular in shape, and upper casing 101 comprises about the symmetrical two parts of light source 115.Upper casing 101 comprises two connecting portions 105 that link to each other with lower casing 102, two frame sections 106 that link to each other with connecting portion 105 respectively and the light block beam 107 that two frame sections 106 are linked together.Wherein in two frame sections 106 of upper casing 101, all be inlaid with light-passing board 108, these light-passing board 108 1 ends extend to connecting portion 105, and the other end extends to light block beam 107 places and keeps fixing.Translateral light-passing board 108 outgoing of the light that light source 115 sends.This light-passing board 108 can be a transparency glass plate.
Because light block beam 107 is between two light-passing boards 108; And be positioned at said light source 115 the place aheads, this light block beam 107 can block the light that light source 115 sends, and makes the zone of floodlight of explosion-suppressing type for mine 100 irradiations dark district occur; Therefore, in light-source chamber 109, be provided with reflective mirror 110.This reflective mirror 110 is positioned at light source 115 rears, and this reflective mirror 110 is towards light-passing board 108 and light block beam 107, and is fixed on the mirror holder 111, and the two ends of mirror holder 111 are fixed on the inwall of lower casing 102 through screw 112.
In conjunction with Fig. 2 and Fig. 3, this reflective mirror 110 is monosymmetric shape, and the middle part is towards the direction of light source 115 protrusion, be used to make the light diffuse reflection that light source 115 sends after, throw away from light-passing board 108.Because reflective mirror 110 towards this shape of light source 115 protrusions, can throw the light that light source 115 sends towards the road both sides, the light intensity of road both sides is strengthened, and make floodlight of explosion-suppressing type for mine 100 can shine fartherly.
The two ends perk of reflective mirror 110 is formed for eliminating first reflector segment 116, second reflector segment 117 in dark district, and they are provided with towards light block beam 107, and light is reflexed to light block beam 107 formed shadow regions.As shown in Figure 4; Light block beam 107 forms dark district A on plane of illumination; The light that first, second reflector segment 116,117 sends light source 115 respectively reflects away from the light-passing board 108 of the same side, on plane of illumination, forms first, second indirect illumination district B, C respectively.When wherein when covering dark district A fully of first, second indirect illumination district B, C, dark district A can be illuminated.Perhaps, when both covered dark district A jointly as first, second indirect illumination district B, C, dark district A can be illuminated.When both all covered dark district A as first, second indirect illumination district B, C, the light that projects dark district A was maximum, makes that the brightness of dark district A is the highest.
Those skilled in the art person can understand, and can omit reflective mirror 110, and only towards light block beam 107 first reflector segment 116, second reflector segment 117 is set.And the quantity of reflector segment can be merely one, as long as the indirect illumination district that it forms can cover dark district fully.
Because the size of reflector segment, angle need the numerous parameter regulation such as distance of size, light block beam 107 according to light block beam 107 distance and the light source 115 to the distance of light source 115, light source 115 to reflector segment to plane of illumination; Different lamps is apart from adopting different reflector segments; Therefore, the parameter condition of reflector segment is not enumerated at this one by one.
The reflective mirror 110 that both sides are symmetrical pinion shape has been shown among the figure, but it also can be other shape, like cambered surface towards the direction protrusion of light source 115.
Because diffuse reflection taken place, the light of projection can be towards a plurality of different directions, make the light of outgoing disperse and evenly, thereby have further eliminated light block beam 107 issuable shades.Reflective mirror 110 can be made up of the little cambered surface of a plurality of multistages, to guarantee light to different direction reflections.
Like Fig. 5 and shown in Figure 6, in the second embodiment of the present invention, repeat no more with the first embodiment something in common.This embodiment has increased the floodlight part on the basis of first embodiment.This floodlight part can be the floodlight plate 113 separate with light-passing board 108; Its quantity is two; Adhere on the inner surface of two light-passing boards 108 respectively, allow light to pass through, the one of which end extends near light block beam 107; Can be concordant with the end of light-passing board 108, the other end may extend to middle part or the other end of light-passing board 108.This floodlight plate 113 can be the striped light-passing board, on the surface of light source 115, is provided with a plurality of zigzag stripeds 114.Floodlight plate 113 also can be a frosted type light-passing board, is matte surface towards the surface of light source 115, realizes the floodlight function.
This floodlight part also can be the part of light-passing board 108, carries out floodlight through direct inner surface at light-passing board 108 and handles, and obtains the floodlight part.This floodlight part can be the striped part that has sawtooth, or the frosted part.And this floodlight part can extend near light block beam 107 by an end, and the other end extends to the middle part of light-passing board 108.In addition, this floodlight part also can cover whole light-passing board 108.After the light that light source 115 sends incides floodlight part, towards each different directions refraction, make the light of outgoing disperse and evenly, thereby eliminated light block beam 107 issuable shades.
Those skilled in the art person should understand, also can adopt this floodlight part separately, and omits reflective mirror 110, can reach same purpose.
