Abstract

The invention provides an LED streetlamp which comprises a lamp housing, an LED light source component, a diffuser and a radiating plate. The diffuser is fixed to the lamp housing, and the diffuser and the lamp housing together form a semi-oval or semi-circular light source chamber. The LED light source component is arranged in the light source chamber and comprises a substrate and a plurality of LED light sources fixed to the substrate; the substrate is fixed to one surface of the radiating plate, tapered radiating burrs are welded to the other surface of the radiating plate, and the diameter of the section of each of the radiating burrs is reduced gradually from a welded end to the other end. The radiating plate is hermetically connected to the lamp housing, and the radiating burrs are arranged between the radiating plate and the lamp housing. Since the radiating burrs are tapered, radiating areas are expanded, ventilation performance of the radiating plate is improved and radiating effect is improved. Since the radiating burrs are arranged in the lamp housing, damages such as deformation of the radiating burrs caused by external force can be avoided.

Description

Technical field

The present invention relates to a kind of LED street lamp.

Background technology

The features such as that LED street lamp has is environment friendly and pollution-free, little power consumption, light efficiency is high, the life-span is long, therefore, LED street lamp will become the optimal selection of reducing energy consumption.What LED street lamp was different from conventional street lamp is, the efficient white light that LED light source adopts low-voltage DC supply, synthesized by GaN based power type blue-ray LED and yellow, there is the distinct advantages such as efficient, safety, energy-saving and environmental protection, life-span length, fast response time, colour rendering index height, can be widely used in road.Outer cover can be with making, high temperature resistant 135 degree that reach, low temperature resistant reaching-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 formation sheet, the air permeability relative deficiency of this heat sink, affects the heat radiation of heat sink.

Summary of the invention

The object of this invention is to provide a kind of LED street lamp, 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 assembly, diffuser, heat sink, diffuser is fixed on lamp housing, diffuser and lamp housing are formed with half elliptic or semicircular light source chamber, in light source chamber, be provided with LED light source assembly, LED light source assembly 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 heat radiation chamber, heat radiation burr is located in heat radiation chamber.

Further, the spacing of adjacent heat radiation burr is greater than the diameter of section of heat radiation burr, between adjacent heat radiation burr, is provided with arc convex.

Further, between adjacent heat radiation burr, be provided with heat radiation cluster parachute, the umbrella heat-sink unit that heat radiation cluster parachute is joined 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 respectively the both sides of heat sink, 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 invention has the beneficial effects as follows: this kind of LED street lamp is taper by heat radiation burr is set, when increasing area of dissipation, improve the performance of ventilating of heat sink, improve radiating effect, and heat radiation burr is arranged in lamp housing, can prevents that external force from causing distortion to wait on heat radiation burr and damaging impact.Between heat radiation burr, arc convex being set can further increase area of dissipation, improves radiating effect.Or between heat radiation burr, heat radiation cluster parachute is set, and can significantly increase area of dissipation, improve radiating efficiency, and cost is lower, is beneficial to production and application.

Accompanying drawing explanation

Fig. 1 is the structural representation of the embodiment of the present invention;

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 assembly, 3-diffuser, 4-heat sink, the 5-burr that dispels the heat, 6-arc convex, the 7-cluster parachute that dispels the heat, the left ventilating opening of 8-, the right ventilating opening of 9-.

The specific embodiment

Below in conjunction with accompanying drawing, describe the preferred embodiments of the present invention in detail.

Embodiment
