Described lamp housing adopts aluminium section bar one-body molded, outward-dipping reflective inclined-plane is provided with inside the sidewall edge of lamp housing, the light that LED lamp bead sends shines on lampshade after reflective slant reflection, and sidewall edge and the reflective inclined-plane of lamp housing form the groove of corresponding snapping lampshade.
Described lamp housing is provided with the corresponding installing plate placing pcb board, and the both sides of installing plate are provided with the draw-in groove coordinating and insert pcb board, and the described inward flange on reflective inclined-plane connects with the dual-side of installing plate.
The two ends of described lamp housing are provided with inner cap and enclosing cover successively, and the junction of inner cap and lamp housing and enclosing cover and inner cap is respectively equipped with waterproof apron.
Described outer covering is provided with U-shaped groove, and the bottom surface of U-shaped groove is provided with the outer wire hole for installing power line, inside covers and is provided with corresponding interior wire hole, and in inside and outside wire hole, outlet plug is equipped with in sealing.
The both sides in the top width direction of described lamp housing form hook groove, and hook groove is snapped with elastic hanger.
Compared with prior art, the beneficial effects of the utility model: adopt isosceles triangle LED lamp bead arrangement mode, reduce the generation of hot spot, improve light efficiency, the position relationship of reasonable layout makes heat radiation impact between LED lamp bead reduce, and reduces light decay, increases service life.And have additional reflective inclined-plane, the peripheral luminous flux of curved surface lampshade is increased, reduces the dark space on lampshade both sides, uniform-illumination on lampshade, thus the effect reaching three-prevention lamp brightness uniformity.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model preferred embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described further.
Refer to Fig. 1, the utility model relates to a kind of Tri-proof light of brightness uniformity, comprise lamp housing 1, be fixed on the LED lamp panel on lamp housing 1, and the lampshade 4 to be tightly connected with lamp housing 1, wherein, LED lamp panel is by pcb board 2, LED lamp bead 3, and constant-current driving power supply (not indicating in figure) is formed, pcb board 2 grafting is fixed on lamp housing 1, LED lamp bead 3 is welded on pcb board 2, LED lamp bead 3 is multiple row and often row are arranged parallel to each other, wherein any one lamp pearl of row arranges two adjacent lamp pearls formation isosceles triangle arrays with another, constant-current driving power supply is fixed in lamp housing 1, and be electrically connected with LED lamp bead 3.The LED lamp panel excellent performance of above-mentioned arrangement architecture, can reduce the generation of hot spot, improves light efficiency.
In the present embodiment, the distance formed between three LED lamp bead 3 in each isosceles triangle array is equal, namely the distance between the LED lamp bead 3 that is adjacent of each LED lamp bead 3 is all equal, is formed equilateral triangle to make three adjacent LED lamp pearls 3 in multiple isosceles triangle array.Can obtain thus, the beeline between LED lamp bead 3 adds
doubly, the position relationship of reasonable layout makes heat radiation impact between LED lamp bead reduce, and reduces light decay, increases service life.
Tri-proof light in the utility model refers to the three-prevention lamp be made up of aluminium alloy extrusions.Lamp housing 1 adopts aluminium section bar integrated injection molding, and it is curved cavity, and the sidewall connected with top by top and both sides is formed.In the cavity of lamp housing 1, form installing plate 12 near sidewall edge, installing plate 12 is provided with draw-in groove along the both sides of lamp housing 1 length direction, and LED lamp panel correspondence is placed on installing plate 12, and both sides of the edge cooperation is inserted in draw-in groove.The reflective inclined-plane 11 connected with the both sides of installing plate 12 is formed in the inner side of the sidewall edge of lamp housing 1, reflective inclined-plane 11 outwards opens inclination, after the light that LED lamp bead 3 is sent is irradiated to reflective inclined-plane 11, can reflex on lampshade 4, thus increase the peripheral luminous flux of lampshade 4, reduce the dark space on lampshade both sides, thus reach the effect of three-prevention lamp brightness uniformity.Lampshade 4 is striped cover, vaporific cover or translucent cover, and the sidewall edge of lamp housing 1 and reflective inclined-plane 11 constitute the groove 13 of strip, and the both sides correspondence sealing of lampshade 4 snaps in groove 13.
