Abstract
The utility model relates to the technical field of LED (light-emitting diode) lamps and particularly discloses an LED street lamp. The LED street lamp comprises a rectangular framework, wherein the rectangular framework comprises two connecting edge strips which are distributed in parallel, end covers which are respectively arranged at one end of each connecting edge strip and lamp caps which are respectively arranged at the other end of each connecting edge strip, a plurality of LED modules which are distributed in parallel are arranged between the two connecting edge strips, a heat dissipation gap is reserved between the adjacent two LED modules, a strip-shaped heat dissipation device is independently arranged on the back surface of each LED module, and the two ends of the strip-shaped heat dissipation devices are connected with the connecting edge strips; each LED module is an AC (alternating current)-LED module; and heat dissipation slots which are arranged on the same sides of the strip-shaped heat dissipation devices are arranged on the lamp caps. Heat emitted by the LED modules can be dissipated from the heat dissipation gaps and the strip-shaped heat dissipation devices. Therefore, the LED street lamp provided by the utility model has the beneficial effects of good heat dissipation performance, high light-emitting efficiency and long service life.
Description
Technical field
The utility model relates to LED technical field of lamps, relates in particular to a kind of LED street lamp.
Background technology
It is high that LED light fixture has luminous efficiency, long service life, and the plurality of advantages such as energy-saving and environmental protection, its use is also more and more universal.Traditional street lamp is all to adopt incandescent light bulb or fluorescent lamp, electricity-saving lamp etc. for illumination, this traditional class light fixture is short service life, luminous efficiency is low, power consumption is large, therefore now a lot of street lamps all adopt LED street lamp, yet the biggest factor that affects LED street lamp service life is heat radiation, and temperature too Gao Shihui causes LED light decay, thereby reduce service life.
Chinese patent Granted publication number: CN202902080U, on April 24 2013 Granted publication day, discloses a kind of LED street lamp, the drive end bearing bracket that comprises LED street lamp, is provided with draw-in groove in drive end bearing bracket, be provided with horizontal tube in draw-in groove, the below of drive end bearing bracket is provided with lamp body, is provided with fixed support in lamp body.There is the installation situation, applied widely that can observe intuitively light fixture.Its weak point is this kind of LED road lamp cooling weak effect, easily causes light decay, thereby affect service life during LED excess Temperature.
Utility model content
The utility model, for deficiency of the prior art, provides a kind of perfect heat-dissipating, and luminous efficiency is high, the LED street lamp of long service life.
To achieve these goals, the utility model adopts following technical scheme:
A kind of LED street lamp, comprise rectangular frame, described rectangular frame comprise two parallel distributions connection edge strip, be located at connect edge strip one end end cap, be located at the lamp holder that connects the edge strip other end, between two connection edge strips, be provided with some parallel distribution LED modules, between two adjacent LED modules, be provided with heat radiation gap, each LED module back side is provided with separately bar shaped radiator, the two ends of bar shaped radiator be connected edge strip and connect.LED module is easy for installation, from heat radiation gap location, can ventilate, dispel the heat, LED module front is luminous, the heat that send two sides of each LED module can dissipate from heat radiation gap location fast, prevent heat accumulation and cause LED module environment temperature too high, bar shaped radiator further increases LED module backside heat, bar shaped radiator can also pass to connection edge strip heat, thereby increase area of dissipation, better heat-radiation effect, therefore the environment temperature that guarantees LED module, in rated temperature range, guarantees stable luminous of LED module, long service life.
As preferably, described LED module is AC-LED module.AC-LED module can directly access in external circuitry, and without external driving power, simple in structure, cost is low, long service life.
As preferably, on lamp holder, be provided with radiating groove with the homonymy of bar shaped radiator.The heat of radiator passes to connection edge strip, connect edge strip and be connected with lamp holder again, so heat dissipates from radiating groove after passing to lamp holder, and radiating groove can play the effect of auxiliary heat dissipation.
As preferably, the center, outer end of lamp holder is provided with connecting hole, and the side of lamp holder is provided with the clamping screw that runs through connecting hole.Connecting hole is convenient to being connected and installed of LED street lamp, after connection, by clamping screw, locks.
Therefore, the utlity model has perfect heat-dissipating, luminous efficiency is high, the beneficial effect of long service life.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
A kind of LED street lamp as depicted in figs. 1 and 2, comprise rectangular frame 1, rectangular frame 1 comprises the connection edge strip 2 of two parallel distributions, be located at the end cap 3 that connects edge strip one end, be located at the lamp holder 4 that connects the edge strip other end, the center, outer end of lamp holder 4 is provided with connecting hole 8, two connect the LED module 5 that is provided with some parallel distributions between edge strip 2, LED module 5 in the present embodiment is AC-LED module, AC-LED module can directly access in external circuitry, without external driving power, simple in structure, cost is low, in design LED street lamp, because without driving power, therefore in design process for line arrangement, structure space arrangements etc. are also more laborsaving, between two adjacent LED modules 5, be provided with heat radiation gap, each LED module 5 back side is provided with separately bar shaped radiator 6, the two ends of bar shaped radiator 6 be connected edge strip 2 and connect, LED module front is luminous, play the effect of night illumination, two side evolutions of heat of each LED module can dissipate from heat radiation gap location fast, prevent heat accumulation and cause LED module environment temperature too high, bar shaped radiator further increases LED module backside heat, bar shaped radiator can also pass to connection edge strip heat, thereby increase area of dissipation, better heat-radiation effect, therefore the environment temperature that guarantees LED module is in rated temperature range, guarantee stable luminous of LED module, long service life, on lamp holder 4, be provided with radiating groove 7 with the homonymy of bar shaped radiator, the heat of radiator passes to connection edge strip, connects edge strip and is connected with lamp holder again, and heat dissipates from radiating groove after passing to lamp holder, and radiating groove can play the effect of auxiliary heat dissipation.Therefore, the utlity model has perfect heat-dissipating, luminous efficiency is high, the beneficial effect of long service life.
The above embodiment has only expressed the specific embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
