Adopt low voltage LED heliolamp described in the utility model, by distinctive S type aluminum profile heat radiator design, make it have the advantage of two-sided bright dipping, increase lighting angle and improved the illumination effect of lamp box, two light sources unconventional design back-to-back simultaneously, heating region does not overlap, and makes light source board obtain good radiating condition.
Accompanying drawing explanation
Fig. 1 is a kind of specific embodiment schematic cross-section of low voltage LED heliolamp described in the utility model;
Fig. 2 illustrates the external structure schematic diagram of low voltage LED heliolamp described in the utility model;
In figure, Reference numeral name is called: 1-shell 2-LED fluorescent tube 3-groove 4-heat sink 5-lamp holder 7-draw-in groove 8-lobe 9-aluminium base.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail.
Embodiment 1
As Fig. 1 illustrates a specific embodiment of low voltage LED heliolamp described in the utility model, comprise shell 1, be positioned at shell two ends lamp holder 5, be positioned at enclosure heat sink 4, be positioned at two light source boards on heat sink; Described heat sink cross section becomes S shape, comprises that 2, two light source boards of two parallel grooves that opening direction is contrary lay respectively in one of them groove 2.
By place separately an independent fluorescent tube in two staggered relative grooves on heat sink, make lamp box comprehensive interior luminous at 360 degree, and because the light-emitting zone of two fluorescent tubes staggers relatively, back does not overlap, improve the radiating condition of LED fluorescent tube, extended the service life of fluorescent tube.
Heat sink can adopt conventional aluminium section bar, and quality is light, cost is low and radiating effect is better.
Light source board can be made up of aluminium base 9 and the LED fluorescent tube being arranged on aluminium base, and the upper surface of LED fluorescent tube flushes with groove 3 opening surfaces, avoids being blocked by recess sidewall, goes out preferably light effect to obtain.
Embodiment 2
The present embodiment has done further improvement to the shell of low voltage LED heliolamp, shell cross section is rounded, outer cover body shape can be common cylindrical shaped, also can be the cylindrical of two ends globulate, shell adopts light plastics, such as off-white color, light yellow etc., the circular cross-section shell of light color makes bright dipping evenly soft.
Shell can adopt conventional optical grade acrylic board, adopts aluminum alloy frame to strengthen, to improve the mechanical strength of lamp box.
Embodiment 3
The present embodiment improves with the mode that is fixedly connected with of shell for heat sink, the mode that conventional lightbank adopts bolt and nut to coordinate more connects, this mode has increased unnecessary structure in lamp box, when lamp box is luminous, easily see bolt or nut shadow shapes by light lamp box shell, affect attractive in appearance, in the present embodiment, enclosure has a pair of lobe inwardly stretching out 8, described heat sink both sides have respectively one with the draw-in groove 7 of lobe form fit.As shown in Figure 1, diameter two ends at circular housing arrange respectively a lobe, heat sink both sides arrange draw-in groove, when installation, lobe 7 is snapped in respectively in draw-in groove 8, adopt this engaging mode to reduce internal structure, provide cost savings, when lamp box is luminous, there is no shade, luminous more evenly attractive in appearance.
