Abstract
The utility model discloses a cellular radiating LED (light-emitting diode) street lamp, which comprises a lamp body, an LED light source, a heat-conducting substrate, and a drive power supply, wherein the LED light source, the heat-conducting substrate and the drive power supply are arranged on the lamp body. The cellular radiating LED street lamp is characterized in that the lamp body is directly used as a radiating base body; the lamp body is of a rectangular shape; the lamp body is formed by honeycomb holes penetrating up and down; the heat-conducting substrate is arranged at the centre part of the lamp body; heat-conducting silicone grease is coated on the heat-conducting substrate; the LED light source is tightly assembled on the heat-conducting substrate by virtue of an annular lamp, a lens, a lens rubber ring and an annular clamp rubber ring; the drive power supply is arranged inside an independent power box; a wire chase box is arranged at one side of the power box; the wire chase box and the rubber ring are sealed when being assembled; an output lead of the drive power supply penetrates into a lead box to be connected with the LED light source; a fixed handle is arranged on the lamp body for fixed installation of the lamp. The device achieves rapidly radiating, reduces use temperature of the light source, protects the light source and prolongs the service life.
Description
Technical field
The utility model relates to lighting, relates in particular to the LED street lamp.
Background technology
Existing street lamp is the LED street lamp especially, its structure is that the heat abstractor, led light source and the driving power that comprise housing and housing inner chamber form, its deficiency is, the heat abstractor of light source is arranged on the inner chamber of housing, heat abstractor mostly is greatly the fin type structure, and the fin that namely has some parallel interval to arrange in lamp body flat plate is by the fin natural heat dissipation, radiating efficiency is low, affects the life-span of led light source; Gap, fin interval is little, and long-term the use can accumulate a large amount of dusts between fin, also affect radiating efficiency; And heat abstractor is arranged on the housing inner chamber, is unfavorable for Air Flow, affected greatly whole radiating efficiency.Therefore be sought after a kind of heat radiation good, the LED street lamp of long service life.
Summary of the invention
The purpose of this utility model is not enough for existing LED road lamp cooling, and the technical problem that service life is short designs a kind of cellular heat dissipation LED road lamp.
A kind of cellular heat dissipation LED road lamp, comprise lamp body and the led light source, heat-conducting substrate, the driving power that are arranged on the lamp body, it is characterized in that, lamp body is directly as heat dissipation base, described lamp body is rectangular-shaped, and its lamp body is formed by the honeycomb of up/down perforation, and heat-conducting substrate is installed in the centre of lamp body, scribble heat-conducting silicone grease on the heat-conducting substrate, led light source is assemblied on the heat-conducting substrate by annular holder, lens, lens cushion rubber, annular holder rubber sealing; Described driving power is arranged at independently in the power pack, and a side of power pack is provided with Wire casing boxes, and during assembling, Wire casing boxes adds cushion rubber and does encapsulation process; The output lead of driving power penetrates wiring duct box and is connected with led light source; Lamp body is provided with integral cast handle, is used for the fixed installation of light fixture.
The utility model has the advantages that: the hot temperature that led light source produces is directly conducted to heat-conducting substrate, reaches lamp body by heat-conducting substrate, by free convection and the heat radiation of lamp body dissipation of heat is fallen.The cellular design of lamp body forms crisscross fin, effectively shortens thermally conductive pathways, has increased greatly area of dissipation; Perforate is penetrating up and down, is beneficial to Air Flow, and dust is difficult for piling up; The stack of above-mentioned effect, lamp body can quick heat radiatings, reduce the light source serviceability temperature, protected light source, prolonged service life.
