Description

The LED illuminating lamp

Technical field

The utility model relates to the illuminating lamp field, specifically, relates to a kind of LED illuminating lamp.

Background technology

LED Chinese full name is a light emitting diode, is a kind of semiconductor that electric energy is converted into visible light.The LED illumination is the new industry that grows up recent years, is characterized in luminous efficiency height, long service life (can reach 100000 hours).Compare with incandescent lamp, electricity-saving lamp conventional lamp etc., the LED lighting does not have sensing units such as vacuum device and high-voltage triggering circuit, and fault rate is low, non-maintaining, response time weak point, and startup is rapid, volume is little, in light weight.Harmful substances such as LED monochromaticjty is good, in the spectra collection, does not have light such as unnecessary infrared, ultraviolet, and is not mercurous, heat and radiation are few, and be flat luminous, high directivity, and discarded object is recyclable, does not pollute, and is typical environmental protection lighting source.Utilize the characteristics of LED can design the light fixture of the various patterns of frivolous compactness.

As everyone knows, generally be used for the high-power LED lamp of street and other area illuminations, after energising is lighted, the heat that LED produced, the mode that all adopts nature to distribute is dispersed in the air usually, so that the LED junction temperature remains on the certain numerical value.Specifically, the heat that LED produced is to be transmitted on the lamp body by aluminium base and heat-conducting silicone grease, and the fin by the lamp body outside is dispersed in the air naturally again.But, there are a lot of defectives in flange-cooled plate lamp body, as: according to the requirement of LED heat dissipation characteristics, the power of LED light fixture is big more, its area of dissipation is just big more, the principle that other rises according to hot-air, the cold and hot air of radiator marginal portion flows easily, and the cold air of radiator core can not obtain replenishing fully, make the convection current fast and effeciently of cold and hot air, hindered distributing of core heat, cause the radiator central portion temp to be higher than the unbalanced phenomena of marginal portion temperature, thereby cause the LED junction temperature of radiator core to raise, surpass LED and allow the junction temperature temperature, final LED brightness is decay or damage sharply, and shortened the service life of LED greatly.

Summary of the invention

For addressing the above problem, the technical scheme that the utility model adopted is:

A kind of LED illuminating lamp, comprise lamp body, cover on the lampshade on the lamp body and be separately fixed at lamp holder, the lamp tail at lamp body two ends, it is characterized in that: described lamp body comprises LED illuminating lamp module group and is separately fixed at left longeron, the right vertical beam of the LED illuminating lamp module group left and right sides; LED illuminating lamp module group by several respectively independently the LED illuminating lamp module of good waterproof performance form, each LED illuminating lamp module is connected in parallel on the power supply circuits.

Say further:

Described LED illuminating lamp module comprises lamp plate and the radiator that is welded with several LED, and lamp plate is fixed on the radiator, and the top of described lamp plate is covered with the printing opacity face shield, and the printing opacity face shield is fixed on the radiator; Be provided with the lens fixed mount between described lamp plate and the printing opacity face shield, the lens fixed mount is fixed on the radiator; Be fixed with several lens on the lens fixed mount, lens are corresponding one by one with LED, and cover on the LED; The water-proof wire joint is installed on the described radiator, and the lead that is connected on the lamp plate is connected with the water-proof wire joint.

Described lampshade is provided with louvre; Be equipped with the heat radiation strip hole on described lamp holder and the lamp tail.

Owing to adopted technique scheme, compared with prior art, the utility model adopts respectively the independently LED illuminating lamp module composition LED illuminating lamp module group of good waterproof performance, cold air can flow from the gap of each module from bottom to top fast, take away the heat on the radiator rapidly, louvre on lampshade, lamp holder and the lamp tail then can be discharged the heat that LED sends in the lampshade fast and effectively, reaches high efficiency radiating effect, prolongs the service life of LED light fixture; In addition, modular structure has very big flexibility, the random road lamp of composite design different capacity and style, to be fit to the illumination needs of different occasions and road section, and, the road lamp of modular construction is very convenient aspect using, safeguarding, can load and unload the operational blocks which partition system of light fixture.

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
