Description

A kind of LED street lamp of module assembled

Technical field

The present invention relates to the LED lighting engineering, particularly a kind of LED street lamp of module assembled.

Background technology

Street lamp is the important component part of city illumination, and traditional street lamp often adopts high-pressure mercury lamp, and high-pressure mercury lamp 360 degree are luminous, and the shortcoming that light loss is large has caused the huge waste of the energy.LED illumination with its directional lighting, the advantages such as power consumption is low, drive characteristic good, fast response time, shock resistance are high, long service life, environmental protection enter into people's the visual field gradually, become the energy-conserving light source of new generation that there is in the world alternative conventional light source advantage most at present, therefore, the LED illumination will become the optimal selection of roadway illumination and energy saving transformation.

At present, one of subject matter that LED illumination application exists is the heat dissipation problem of LED, especially high-power LED illumination, and after heating, the brightness meeting obviously reduces, and light decay is serious, and the life-span reduces.The LED street lamp is mainly dispelled the heat by radiator, and the LED light source of different capacity size need mate the radiator of different size, so the radiator versatility is poor, production cost is high, when application relatively high power LED street lamp, for guaranteeing radiating effect, radiator has higher weight.

Summary of the invention

The object of the present invention is to provide a kind of LED street lamp of module assembled, make LED street lamp heat radiator highly versatile, applicable different capacity requirement, reduce production costs, and guarantees radiating effect.

For achieving the above object, the present invention is achieved by the following technical solutions.

A kind of LED street lamp of module assembled, it is characterized in that, comprise radiating subassembly, power supply module and at least one group of LED module, described LED module comprises light source assembly, described LED module is installed on the front of radiating subassembly, and described power supply module is installed in the installing hole at the radiating subassembly back side.

Characteristics of the present invention and further the improvement are:

Described radiating subassembly is aluminium alloy extrusions, and described aluminium alloy extrusions is integrated section bar or assembling section bar.

The vertical symmetry axis of described radiating subassembly substrate back is provided with circular hole slot K extending longitudinally, and the shape in K hole is convenient to install all kinds of light pole fixed supports, driving power or controller.

Both sides, described radiating subassembly substrate both sides all have height profile be the convex arc line longitudinally process radiation tooth, the radiation tooth height is taken as 20-55mm, radiation tooth thickness is taken as 2-3mm, the radiation tooth Surface Machining is fluted, has obviously increased cooling surface area.This form arrangement has guaranteed to obtain best radiating effect in the situation that heatsink mass is less.

The outermost radiation tooth top side of described radiating subassembly substrate front side both sides is processed with groove, in order to light diffusing sheet (astigmatism plate) to be installed, reduces the dazzle of light fixture.

Described radiating subassembly rear and front end face is equipped with baffle plate, and baffle plate is screwed at hot assembly end face, to meet the profile that forms street lamp.

Described radiating subassembly is aluminium alloy extrusions; Can significantly reduce the production cost of radiator.

Described LED light source module itself has been made Seal Design (sealing ring+water joint) to light source, so need not carry out any encapsulation process when this module is arranged on radiator again.The module light source is applied to the instructions for use of different roads to adapt to the modularization light fixture according to road light distribution requirements capable of choosing multiple light-distribution lens (rectangular light spot luminous intensity distribution, bat shape hot spot luminous intensity distribution etc.).

Light source module is comprised of the water joint of radiating bottom plate, light-distribution lens, sealing ring, trim ring and the sealing wire of light source, installation light source.

The LED street lamp of module assembled of the present invention, comprise radiating subassembly, power supply module and at least one group of LED module, described LED module comprises light source assembly, and described LED module is installed on the front of radiating subassembly, and described power supply module is installed in the back side hole slot K of radiating subassembly; The LED street lamp of this module assembled, make LED street lamp heat radiator highly versatile, and applicable different capacity requirement, reduce production costs, and guarantees radiating effect.
