Abstract
The utility model discloses an LED road lamp comprising a front shell, a rear shell, a fixed lamp stand holder and a transparent lampshade, and further comprises a transformer which is fixedly arranged on the rear shell, and an LED lamp board which is connected with the front shell, wherein a plurality of radiating fins are arranged on the external surface of the rear shell, at least one groove is arranged on the inner surface of the front shell, a plurality of the radiating fins are arranged in the groove, the arrangement of the radiating fins is convenient to guide the heat of the LED lamp board into air, which dissipates heat of an LED in time, thereby guaranteeing the sufficient heat dissipation of a LED road lamp, prolonging the service life of the LED, reducing the light decay and even enabling the light decay to be ignored, and guaranteeing the brightness of the LED road lamp.
Description
Technical field
The utility model relates to a kind of street lamp, relates in particular to a kind of with the street lamp of LED as light source.
Background technology
Existing LED street lamp utilizes aluminium alloy heat loss through conduction principle to have the following disadvantages: the temperature of LED and ballast heat radiation can reduction LED lamp plate and ballast when metallic copper or aluminium alloy connect LED lamp plate and ballast, when LED quantity is above above 32, this mode just can not be dispersed into the temperature of LED and ballast in the air effectively, thereby cause the temperature in the whole lamp box to reach more than 70 degrees centigrade, the LED street lamp combines, the appearance sealing, when temperature raises, the just very fast decay of LED, until extinguishing, can not use.
The utility model content
The purpose of this utility model is to provide a kind of LED street lamp, can solve the problem of traditional LED road lamp cooling, and LED street lamp temperature is controlled within 55 degrees centigrade, prolongs the service life of LED street lamp.
In order to achieve the above object, the technical scheme that the utility model adopted is: a kind of LED street lamp, comprise fore shell, back cover, fixed light pole socket, Transparent lamp shade, also comprise transformer that is fixedly arranged on the back cover and the LED lamp plate that links to each other with fore shell, on the outer surface of back cover, be provided with some fin, be provided with a groove on the described fore shell inner surface at least, be provided with several cooling fins in the groove, the setting of fin is convenient to the heat of LED lamp plate is exported in the air, in time dispels the heat to LED.
At least be provided with on the inner surface of described back cover one with the corresponding groove of the groove of being located at the fore shell inner surface, described groove is deep-slotted chip breaker, the groove that while has several corresponding cross sections on header board and the contacted surface of plate, back be arc, and its length all length with header board and back plate is identical, therefore, and when header board combines with the back plate, then form several through holes, in the deep-slotted chip breaker of each fore shell, be provided with several cooling fins, therefore, guaranteed that the heat of LED lamp plate in time distributes.
Inner surface at described fore shell is provided with two T shape raised lines at least, and is provided with two and the corresponding T-slot of aforementioned T shape raised line on the inner surface of back cover at least, and the setting of this structure is to be convenient to fore shell and back cover are fixed together.
Described Transparent lamp shade is located on the fore shell, also is provided with reflecting plate between Transparent lamp shade and LED lamp plate, and the light of being convenient to the LED generation comes out uniformly.
After adopting said structure, because of the deep-slotted chip breaker on the fore shell identical with deep-slotted chip breaker on the back cover because of diameter, when fore shell and back cover lump together, form a through hole, then the heat of LED lamp group generation conducts to fore shell by lamp plate, fore shell arrives through hole by fin conductive provided thereon, become 15 degree angles when mounted with light pole because of street lamp simultaneously, therefore, a part of heat is discharged in the air by through hole, and another part is delivered to the heat of back cover and then discharges by the fin of being located on the back cover, thereby guaranteed that the LED road lamp cooling is abundant, make the LED long service life, light decay diminishes even light decay becomes and can ignore, and has guaranteed the brightness of LED street lamp.
