Abstract
The utility model relates to an LED (Light-Emitting Diode) module and a street lamp. The LED module comprises an aluminum base plate, an LED lamp bead, a clamp plate and radiating fins, wherein the aluminum base plate comprises a main part and lateral wing parts, wherein the lateral parts are arranged on both ends of the main part; the radiating fins are fixed on the main part and distributed perpendicular to the main part; the width of the main part is less than the widths of the radiating fins; the clamp plate fixes the LED lamp bead on the main part; the street lamp adopts the LED module. According to the LED module, the widths of the radiating fins are more than the width of the main part of the aluminum base plate, and a part of the radiating fins exceeds the main part of the aluminum base plate, so that an air flow opening is formed below the adhered position of the radiating fins of a front LED module and a rear LED module when LED modules are spliced; air flows enter and exit from the air flow port without being obstructed by the aluminum base plate, so that the phenomenon of heating concentration is reduced, the radiating is uniform, and the life of the LED module and the street lamp which adopts the LED module is prolonged.
Description
Technical field
The utility model relates to lighting apparatus, relates in particular to a kind of LED module and street lamp.
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 is converted into luminous energy by electric energy, and it is a kind of solid-state cold light source, and one of them maximum characteristic is little power consumptions, and therefore, the LED street lamp will become the optimal selection of roadway illumination and energy saving transformation.
The luminous parts of LED street lamp are the LED module.Common street lamp can use the work that is stitched together of a plurality of LED modules, to reach required illuminance, but the LED module be stitched together is because the fin sheet is relatively elongated, easily produce heating concentrates in the place be in contact with one another, and the LED module fin mediated is difficult for heat radiation, cause whole radiating effect inhomogeneous, affected the service life of LED module and street lamp.
The utility model content
The purpose of this utility model is to provide a kind of LED module and street lamp, makes the LED module of splicing can dispel the heat evenly, to improve the service life of LED module and street lamp.
For achieving the above object, the utility model is by the following technical solutions: a kind of LED module, comprise aluminium base, LED lamp pearl, clamping plate and fin, aluminium base comprises stem portion and flank section, flank section is located at the two ends of stem portion, fin is fixed on stem portion and perpendicular to stem portion and distributes, and the width of stem portion is less than the width of fin, and clamping plate are fixed in LED lamp pearl on stem portion.
Further, on the width along stem portion, the part that fin exceeds than stem portion is laid in the both sides of stem portion.
Further, on the width along stem portion, the part that fin exceeds than stem portion is located at a side of stem portion.
Further, flank section and stem portion junction are stairstepping.
Further, flank section is provided with the U-shaped groove for mounting screw.
Further, stem portion is provided with the screwed hole for strap.
The invention also discloses a kind of street lamp, comprise the upper cover and the lower cover that are mutually permanently connected, this street lamp also comprises above-described LED module, and the LED module is located between upper cover and lower cover and runs through lower cover, and LED lamp pearl exposes to the below of lower cover.
Further, the quantity of LED module is the width arranged distribution of 4, LED module along stem portion, and the fin between the LED module of front and back is mutually supported and is close to.
The utility model beneficial effect compared with prior art is:
(1) fin of the present utility model is larger than the width of the stem portion of aluminium base, make fin have part to exceed the stem portion of aluminium base, thereby when the LED module is stitched together, the below that the fin of front and back LED module is close to place has formed airflow orifice, air-flow can not be subject to stopping of aluminium base from the airflow orifice turnover, slowed down the concentration phenomenon of heating, made radiating effect more even, the life-span of having improved the LED module and having used the street lamp of this LED module.
(2) part that fin of the present utility model exceeds than stem portion is laid in the both sides of stem portion, such structure makes the LED module below the contact position of fin, an airflow orifice must be arranged before and after assurance in splicing, has improved the property easy to install and use of LED module.
(3) street lamp of the present utility model has adopted the LED module of above structure, its airflow orifice has increased the air turnover amount of street lamp, not only improve the radiating effect of LED module, can also improve the radiating effect of inner other heat generating members of street lamp, and then the service life of having improved street lamp.

The specific embodiment
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment, the technical solution of the utility model is described further and illustrates.
On the width along stem portion 11, the part that fin 20 exceeds than stem portion 11 is laid in the both sides of stem portion 11.Such structure makes LED module 100 below the contact position of fin 20, an airflow orifice 101 must be arranged before and after assurance in splicing, has improved the property easy to install and use of LED module 100.
The road lighting lantern body structure of the utility model the first embodiment as shown in Figure 5.This street lamp comprises the upper cover 41 that is mutually permanently connected and the LED module 100 of lower cover 42 and the first embodiment.LED module 100 is located between upper cover 41 and lower cover 42 and runs through lower cover 42.LED lamp pearl 32 exposes to the below of lower cover 42.The quantity of LED module 100 is the width arranged distribution of 4, LED module 100 along stem portion 11, and the fin 20 between front and back LED module 100 is mutually supported and is close to.Street lamp has adopted the LED module 100 of the first embodiment, its airflow orifice 101 has increased the air turnover amount of street lamp, not only improve the radiating effect of LED module 100, can also improve the radiating effect of inner other heat generating members of street lamp, and then the service life of having improved street lamp.
