Description

The LED street lamp

Technical field

The utility model relates to LED illuminating lamp technical field, refers in particular to a kind of LED illuminating lamp that is used for road lighting.

Background technology

LED Chinese full name is a light emitting diode, a kind of semiconductor that electric energy can be converted into visible light.The LED illumination is the new industry that grows up recent years, the characteristics of LED illumination: the luminous efficiency height, and one two watts LED lamp is equivalent to the illuminating effect of one 15 watts ordinary incandescent lamp bulb; Long service life, LED lamp service life is the longest to reach 100000 hours; LED is a semiconductor element, compares with electronic energy-saving lamp with incandescent lamp, does not have sensing units such as vacuum device and high-voltage triggering circuit, and fault is extremely low, can freedom from repairs; Response time is short, has only for 60 sodium seconds, starts very rapid; Volume is little, in light weight.Utilize its characteristics can design the light fixture of not only thin, not only light but also compact all styles of; LED is bright in luster abundant.It is changeful that color saturation reaches the different photochromic combinations of 130% full color, utilizes sequential control circuit, more can reach colourful dynamic change effect; Harmful substances such as monochromaticjty is good, in the LED spectra collection, does not have spectrum such as unnecessary infrared, ultraviolet, and is not mercurous, heat, radiation seldom belong to typical green illumination light source, and discarded object is recyclable, do not pollute; Single led luminous flux is little.Single led luminous flux research level can reach 120lm/W at present, and the horizontal 75lm/W of industrialized product is flat luminous, high directivity.

As everyone knows, some are used for the high-power LED lamp of street and road and other area illuminations, and the heat that LED produced when lighting all is that the mode that adopts nature to distribute is dispersed into the space with heat usually, and the LED junction temperature is remained on the numerical value.Concrete grammar is earlier LED to be welded on the aluminium base that has circuit and an one deck thin dielectric layer, passes to lamp housing again by aluminium base and heat-conducting silicone grease then, and the fin by the lamp housing outside is dispersed into the space the most naturally with heat again, thereby reaches radiating effect.But, flange-cooled plate lamp housing is being deposited a lot of defectives, as: according to the requirement of LED heat dissipation characteristics, the power of LED light fixture is big more, the area of dissipation of light fixture is just big more, the reason that rises according to hot-air in addition, the cold and hot air in radiator edge flows easily, and the cold air of radiator core is not easy to obtain to replenish fully, make the convection current fast and effectively of cold and hot air, hindered distributing of core heat, caused the radiator central temperature to be higher than the unbalanced phenomena of lip temperature, thereby caused the LED junction temperature at radiator center to raise, surpassed LED and allow the junction temperature temperature, final LED brightness is decay or damage sharply, makes LED not reach the premium properties of the long service life that was had originally.

The utility model content

The purpose of this utility model is to provide a kind of LED lamp that is used for road lighting.

For addressing the above problem, LED lamp of the present utility model, comprise LED lamp plate, a left shell and a right shell body that combines by plurality of modules and be connected left shell and right shell body between cover body, leave certain clearance between every two adjacent modules, module is fixed between left shell and the right shell body by connector at two ends, each module all has separately independently panel, radiator, lens and sealing device, circuit between each module is provided with evenly distributed through hole for being connected in parallel on cover body.

LED lamp of the present utility model also comprises and has a following feature:

Described radiator and panel are fastenedly connected by screw;

Also be with a panel sealing ring on the described panel, be covered with a lens sealing ring on lens, the lens sealing ring is attached on the panel and with panel and is sealed and matched mutually, is with the wire seal circle in wire hole;

Described radiator is distributed with wire hole, draw-in groove and fin and waterproof bar, wire hole break-through radiator, the waterproof bar is located at the inboard of draw-in groove, fin is evenly arranged on the radiator, the length of fin is greater than the width of radiator, wire hole, draw-in groove and waterproof bar all are arranged on the two ends place of fin, also are provided with the locating hole that is used for fixing usefulness in the edge of heat sink;

Described LED lamp plate and left shell and right shell body are all carried out no cloche pattern.

Compared with prior art, LED lamp of the present utility model, with LED lamp plate modularization, be independently sealing device on each piece module, the scioptics sealing ring is to the sealing of lens, the sealing of panel sealing circle counter plate and wire seal circle are to the sealing of electric wire, by this sealing of three layers, can guarantee each independently the LED lamp plate have good sealed waterproof effect, even expose and outside housing, also do not influence its normal use, connect with connector between each module, large-area strap shape radiator is divided into several small sizes and separate little radiator, leave certain clearance between each adjacent modules, so that cold air rapid fluxion strap is from bottom to top walked the heat on the radiator, thereby the LED junction temperature is controlled in the desirable scope, and this modular structure has very big flexibility, can arbitrarily design the street lamp of different capacity and different-style, to be fit to different occasions, the needs of highway section illumination, lampshade adopts the structure of even distribution through hole on cover body, the through hole of fine and closely woven distribution can be discharged the heat that the LED lamp sends in the lampshade fast and effectively, reach high efficiency radiating effect, prolong the service life of LED lamp, also increased light transmission on the other hand.
