Abstract
The utility model discloses a radiating device for LED street lamps, which adopts a hollow lamp panel for convection radiating based on the prior art. The lamp panel of the LED lamp is designed to be a rectangular hollow lamp panel, and the upper surface of the hollow lamp panel is provided with a plurality of radiating fins and cylinder-shaped radiating holes, wherein, two radiating fins are respectively arranged on the long frame of the hollow lamp panel, and the other radiating fins are respectively arranged on the hollow frame of the hollow lamp panel; and a cylinder-shaped radiating hole is respectively arranged under each radiating fin; the center line of the cylinder-shaped radiating hole is parallel to the long sides of the radiating fins and the hollow lamp panel. The radiating device is arranged on a lamp pole, and the included angle between the long side of the hollow lamp pane and the lamp pole is larger than 90 degrees and less than 180 degrees, thus improving the convection heat radiating effect. The utility model can resolve the difficult radiating problem of the prior art, improves the lightness of the street lamp, and has the advantages of safety and reliability when being used continuously.
Description
Technical field
The utility model relates to lighting technical field, particularly relates to a kind of radiating mode that uses point source of light, specifically a kind of radiator structure that is used for the LED street lamp.
Background technology
Common 3W, the 5W great power LED of the many employings of transitional street lamps.With this great power LED as light source, its luminous efficiency height, power consumption is little, meets the requirement of environmental protection and energy saving, has broad application prospects.But on this class light fixture, also be not equipped with heat abstractor at present or radiating effect is relatively poor, diffusing if the heat that is produced can not in time be arranged, will form light decay, will cause adverse effect to light extraction efficiency, service life and the security of LED.
The utility model content
The purpose of this utility model is in order to solve existing LED street lamp in the problem that exists aspect the heat radiation, to be provided for a kind of heat abstractor of the LED of being used for street lamp, guaranteeing that the heat that is produced when street lamp continues to light can distribute timely.
The technical solution of the utility model is on the basis of existing technology, adopts hollow lamp plate to carry out heat loss through convection.Specifically, the utility model is designed to the hollow lamp plate of rectangle with the lamp plate of LED lamp, at the upper surface of hollow lamp plate fin and cylindrical louvre is set.
Described fin is many, wherein there are two fin to be contained in respectively on the long margin frame on both sides of hollow lamp plate, remaining fin device is provided with a cylindrical louvre under every on hollow frame fin on the hollow frame of lamp plate, be used to strengthen radiating effect.
The center line of described cylindrical louvre is parallel with the long limit of fin and hollow lamp plate.
Described heat abstractor is installed on the lamp stand, and the long limit of its hollow lamp plate and the angle between the lamp stand less than 180 °, make heat abstractor and air produce good convection current greater than 90 °.
The utility model advantage compared with prior art is:
1, because the lamp plate that the utility model adopts is hollow, the lamp plate upper surface is equipped with some fin and adopts the convection type heat radiation, solved the problem of common road lamp cooling difficulty, the heat that is produced when making street lamp continue to light can in time distribute, and has improved the security of light fixture, reliable energy and service life;
2, on probation through manufacturing experimently, compared with the prior art, the semiconductor light sources heat dispersion be improved significantly, improved the utilization ratio of light.

The specific embodiment
With reference to Fig. 1 a, Fig. 1 b and Fig. 1 c, great power LED 5 of the present utility model is welded on the circuit board 4 that is coated with conduction estersil, and circuit board 4 is contained in the lower surface of lamp plate 3.Lamp plate 3 is hollow-core constructions, at this hollow lamp plate 3 upper surfaces dress fin 1 and cylindrical louvre 2.For guaranteeing radiating effect, described fin 1 is designed to multi-disc.Shown in Fig. 1 a～Fig. 1 c, the utility model is preferably seven, wherein has two fin to be distributed on two long margin frames of hollow lamp plate 3, and remaining is distributed on the hollow frame of lamp plate, the fin on two frames, every fin on hollow frame is arranged with a cylindrical louvre 2.The center line of this cylindrical louvre is parallel with the long limit of fin 1 and hollow lamp plate 3.Guarantee air unimpeded flowing on louvre, fin, improve radiating effect.
According to shown in Figure 2, the utility model LED heat abstractor is installed on the lamp stand 6, make the long limit of hollow lamp plate 3 and the angle between the lamp stand 6 greater than 90 °, less than 180 °, guaranteed the heat loss through convection ability of heat abstractor and air.
