LED street lamp has the features such as environment friendly and pollution-free, little power consumption, light efficiency are high, the life-span is long, and therefore, LED street lamp will become the optimal selection of reducing energy consumption.LED street lamp and conventional street lamp unlike, LED light source adopts low-voltage DC supply, by GaN base power-type blue-ray LED and the yellow efficient white light synthesized, there is the particular advantages such as efficient, safety, energy-saving and environmental protection, life-span length, fast response time, colour rendering index height, can road be widely used in.Outer cover with making, high temperature resistantly can reach 135 degree, low temperature resistantly reaches-45 degree.
When the use of street lamp, good heat radiation is carried out in the caloric requirement that light source produces, and makes street lamp have longer service life, and the heat sink in existing light fixture adopts tabular or forms sheet, the air permeability relative deficiency of this heat sink, affects the heat radiation of heat sink.
Utility model content
The purpose of this utility model is to provide a kind of LED street lamp, and cost is low, and the performance of ventilating of heat sink is better, and radiating effect is more excellent, solves the above-mentioned problems in the prior art.
A kind of LED street lamp, comprise lamp housing, LED light source component, diffuser, heat sink, diffuser is fixed on lamp housing, diffuser and lamp housing are formed with half elliptic or semicircular light source chamber, LED light source component is provided with in light source chamber, LED light source component comprises substrate and is fixed on the some LED light sources on substrate, substrate is fixed on the one side of heat sink, the another side of heat sink is welded with heat radiation burr, heat radiation burr is taper, the diameter of section of heat radiation burr is reduced to the other end gradually by welding ends, heat sink is sealedly connected on lamp housing, heat sink and lamp housing form the chamber that dispels the heat, heat radiation burr is located at heat dissipation cavity indoor.
Further, the spacing of adjacent heat radiation burr is greater than the diameter of section of heat radiation burr, is provided with arc convex between adjacent heat radiation burr.
Further, be provided with heat radiation cluster parachute between adjacent heat radiation burr, the umbrella heat-sink unit that heat radiation cluster parachute is connected successively by some first places forms.
Further, lamp housing is provided with left ventilating opening, right ventilating opening, and left ventilating opening, right ventilating opening are located at the both sides of heat sink respectively, and left ventilating opening, right ventilating opening are all communicated with heat radiation chamber.
Further, described diffuser adopts the half elliptic diffuser that transparent resin is made.
The beneficial effects of the utility model are: this kind of LED street lamp, are taper, while increasing area of dissipation by arranging heat radiation burr, improve the performance of ventilating of heat sink, improve radiating effect, and the burr that dispels the heat is arranged in lamp housing, can prevents external force from causing distortion to wait on heat radiation burr and damage impact.Arc convex is set between heat radiation burr and can increases area of dissipation further, improve radiating effect.Or heat radiation cluster parachute is set between heat radiation burr, significantly can increase area of dissipation, improve radiating efficiency, and cost be lower, is beneficial to production and application.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation that embodiment arranges heat radiation burr and heat radiation cluster parachute;
Wherein: 1-lamp housing, 2-LED light source component, 3-diffuser, 4-heat sink, 5-dispels the heat burr, 6-arc convex, and 7-dispels the heat cluster parachute, the left ventilating opening of 8-, the right ventilating opening of 9-.
Detailed description of the invention
Preferred embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
Embodiment
A kind of LED street lamp, comprise lamp housing 1, LED light source component 2, diffuser 3, heat sink 4, diffuser 3 is fixed on lamp housing 1, diffuser 3 and lamp housing 1 are formed with half elliptic or semicircular light source chamber, LED light source component 2 is provided with in light source chamber, LED light source component 2 comprises substrate and is fixed on the some LED light sources on substrate, substrate is fixed on the one side of heat sink 4, the another side of heat sink 4 is welded with heat radiation burr 5, heat radiation burr 5 is taper, the diameter of section of heat radiation burr 5 is reduced to the other end gradually by welding ends, heat sink 4 is sealedly connected on lamp housing 1, heat sink 4 and lamp housing 1 form the chamber that dispels the heat, heat radiation burr 5 is located at heat dissipation cavity indoor.The spacing of adjacent heat radiation burr 5 is greater than the diameter of section of heat radiation burr 5, is provided with arc convex 6 between adjacent heat radiation burr 5.Lamp housing 1 is provided with left ventilating opening 8, right ventilating opening 9, and left ventilating opening 8, right ventilating opening 9 are located at the both sides of heat sink 4 respectively, and left ventilating opening 8, right ventilating opening 9 are all communicated with heat radiation chamber.
By arranging heat radiation burr 5 for taper, while increasing area of dissipation, improving the performance of ventilating of heat sink 4, improve radiating effect, and the burr 5 that dispels the heat being arranged in lamp housing 1, can prevent external force from causing distortion to wait on heat radiation burr 5 and damage impact.Arc convex 6 is set between heat radiation burr 5 and can increases area of dissipation further, improve radiating effect.Left ventilating opening 8, right ventilating opening 9 and heat radiation chamber, thus make the heat radiation burr 5 of heat dissipation cavity indoor carry out sufficient heat exchange with arc convex 6 and outside air, improve radiating efficiency.The opening direction of left ventilating opening 8, right ventilating opening 9 can be set to downwards, can reduce or remit falling into of dust or other foreign material.
