Description

Directed heat dissipation type lightweight LED modular street lamp

Technical field

The present invention relates to a kind of street lamp, specifically is the used LED modular street lamps of occasion such as a kind of road lighting, garden and park illumination.

Background technology

Existing LED lamp post structure is various, is mainly the three major types type, and a kind of is the integral die-cast mould, and whole lamp heat radiation is one, and a kind of in addition is modular structure, is mostly to adopt two groups of above module groups of symmetrical expression.A kind of in addition is to adopt the integrated module of high-power height, and the plurality of LEDs chip is concentrated on the very little substrate, and entire module is being passed through any to heat radiation all around.

Existing LED street lamp all has big defective on heat conduction and temperature balance; Integral die-cast structure LED street lamp; The LED street lamp of every kind of power of underaction all need installed also inconvenience from new design radiator structure on using, and integral die-cast is because area is bigger; Also need use full wafer glass waterproof behind the secondary optical lens, cause the light consume.Symmetrical structure LED street lamp heat distribution is unbalanced, and heat concentrates on the module middle part on monolateral modular structure, and single symmetrical structure adopts and leans on the fin at LED street lamp middle part maximum; Just single led module fin leans on light fixture outside fin minimum; Lean on middle maximum, but the heat of monolateral LED module concentrates on mainly in the middle of the module, module is but less at the radiating fin at middle part; Be unfavorable for heat balance, had a strong impact on whole LED street lamp service life.This structure of high integrated LED modular street lamp is least reasonable; The heat of concentrating any with height is to emission all around, and the concentrated heat of LED itself will exceed one times than radiating piece has a surplus, as the heat source of generation; High concentrate heat under the full heat situation to around emitting heat quantity; The module long-term work has a strong impact on service life in the environment up to the twice temperature, this design is not used fully and used in working time of working every day and reaches in the road lighting more than 8 hours.

Summary of the invention

In order to overcome above-mentioned deficiency, the object of the present invention is to provide the directed heat dissipation type lightweight LED modular street lamp of a kind of good heat dissipation effect, long service life.

To achieve these goals, the technical scheme of the present invention's employing is:

Directed heat dissipation type lightweight LED modular street lamp; It is characterized in that: it is to be made up of lamp holder, two support arms, two above LED modules, lamp tail, tail-hood, driving power and installation tube; Two above LED modules are located on two support arms that are parallel to each other side by side, and two support arm one ends are connected with lamp holder, and the other end is connected with the lamp tail; Driving power is located in the cavity of lamp tail, and an end of installation tube extend in the lamp tail and with tail-hood to be fixed; Be arranged side by side a plurality of fin in said each LED module, each fin is parallel with support arm, is positioned at minimum, the middle fin width maximum of width of the fin on both sides, and the width of fin becomes big by both sides to the centre gradually.

Said LED module is to be made up of a plurality of LED lamps, heat-conducting plate and radiator; Said radiator is by heat radiation matrix, a plurality of fin, light-passing board and fixed frame, and a plurality of fin are distributed in the reverse side of heat radiation matrix and vertical with the heat radiation matrix, the light-passing board frame that is fixed; Be fixed on the front of heat radiation matrix; Heat-conducting plate is located between light-passing board and the heat radiation matrix, and a plurality of LED lamps are located on the heat-conducting plate, are distributed with on the said light-passing board and the corresponding lens of each LED lamp.

Be provided with water proof ring between said heat radiation matrix and the fixed frame.

Beneficial effect of the present invention: because lamp housing is to be made up of lamp holder, two support arms and lamp tail, so reasonable integral structure, weight is lighter; Owing to adopt above-mentioned version, led light source adopts micro-structural, directly through the optical lens luminous intensity distribution, has reduced the light consume to greatest extent; Owing to adopt the width of fin to become big structure gradually to the centre,, make the temperature of whole LED module reach balance, thereby make its performance more reliable and more stable to strengthen the heat radiation dynamics of the high part of medium temperature by both sides.
