Description

The LED road lighting lamp

(1) technical field

The utility model relates to a kind of street lamp, especially relates to a kind of LED road lighting lamp, is used for road lighting, belongs to lighting field.

(2) background technology

Street lamp is the indispensable basic common structure of modern society, is widely used in road lightings at different levels; Along with the LED continuous advancement in technology, the LED street lamp has also obtained using widely.But existing conventional LED street lamp exists following deficiency:

(1) conventional LED road-light light-source is generally and adopts the series-parallel mode of single LEDs on the PCB substrate, because single LEDs luminous power is less, therefore often needs tens of even up to a hundred LEDs, causes LED street lamp size huge, complex structure;

(2) and because single LEDs quantity is too much, luminously too disperse, cause in use having considerable part light not to be fully used, caused waste of electric energy;

(3) simultaneously because single LEDs is arranged on the PCB base plan, make the lighting angle of LED can only be confined in 180 ° the plane, shadow surface is narrow;

(4) conventional LED street lamp utilizes self housing to dispel the heat usually, and radiating effect is poor.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of simple in structure, energy saving, wide, the significant LED road lighting lamp of heat radiation of irradiation are provided.

The purpose of this utility model is achieved in that a kind of LED road lighting lamp, include shell body, renovate, radiating subassembly, led light source, bearing assembly, power supply unit, cover plate, buckle be connected rotational structure;

Described shell body includes main casing, left frame and left frame, described main casing bottom is arranged with two base track grooves in parallel, described main casing inwall both sides are parallel to be symmetrically arranged with two inner track grooves, be provided with a perforate in the middle of the described left frame, described left frame and left frame are arranged at the two ends of main casing;

Described radiating subassembly includes radiator and support, and described support is fixed in an end of the base track groove of main casing, and described radiator is fixed on the support;

Described led light source includes LED base, LED integrated package and LED briquetting, described LED base top is arranged with two inclined-planes, described LED base is fixedly set in the upper surface of radiator, and described LED integrated package is arranged on two inclined-planes of LED base, and described LED briquetting is arranged on the LED integrated package;

Described bearing assembly includes bearing support and press strip, and described bearing support is fixed in the other end of the base track groove of main casing, and described bearing support two sides are fixed on the inner track groove, and described press strip is fixed in the bottom of bearing support; Described power supply unit is fixedly set in the both sides of bearing support, and described power supply unit is connected to the LED integrated package by lead; Described cover plate is fixedly attached to bearing support top flap place;

Described renovate to include renovate housing, translucent cover and reflector, described translucent cover is arranged at renovates outer arch, described reflector is a bowl structure, is arranged to renovate outer frame bottom, described reflector bottom has a rectangle opening;

The described side of renovating is connected to main casing by buckle; The described opposite side of renovating is connected to main casing by connecting rotational structure; Two inclined-planes of described LED base all become 15 ° of inclination angles with the bottom surface; The junction of described all parts is coated with marine glue.

The beneficial effects of the utility model are: owing to use the LED integrated package as illuminating source, no longer need single LEDs of One's name is legion and huge PCB substrate, make the LED lamp post structure oversimplify; After adopting the LED integrated package simultaneously, the light emitting source area dwindles greatly, makes luminous more concentratedly, and light-use is more abundant, thereby has saved a large amount of electric energy; Because the inclined-plane that the LED integrated package is placed becomes 15 ° of angles with the bottom surface, make the lighting angle of LED street lamp reach 210 °, has increased the range of exposures of LED street lamp; In LED street lamp housing, be provided with special radiator the LED integrated package is dispelled the heat, compare, increased area of dissipation, make radiating effect more obvious with conventional LED street lamp.
