Abstract
The invention discloses a LE D street lamp, comprising a lampshade and a paster LED lamp set arranged in the lampshade, wherein the paster LED lamp set is welded on a lamp panel, and a heat radiating fin is arranged on one side of the lampshade backing to the paster LED lamp set. The lamp panel sequentially comprises a circuit board on which the paster LED lamp set is welded, a heat conduction fiberboard and a heat conduction metal panel. The LED street lamp of the invention emits the heat produced when the paster LED lamp set works through the heat conduction fiberboard and the heat conduction metal panel on the lamp panel, heat is transferred to the heat conduction metal panel through the heat conduction fiberboard, and then to the heat radiating fin or the lampshade and last to the outside through the heat conduction metal panel. The LED street lamp of the invention has good heat radiation capacity under a closed condition, and the service life of the LED street lamp is prolonged.
Description
Technical field
The present invention relates to a kind of light fixture, relate in particular to a kind of LED street lamp.
Background technology
In recent years, because plurality of advantages such as long service life, energy consumption that the LED light fixture has are low, rich color replace conventional lamp such as tengsten lamp gradually.
But, common LED lamp is generally 1 to 3 watt on power, because single LED lamp heating is concentrated relatively, the heat of its generation is bigger, and it is very difficult at effectively airtight fluorescent tube space heat dissipation, LED lamp place, long-time luminous back heat is higher, thereby causes LED lamp pearl to shorten greatly service life, and the heat of generation is not easy to dissipate.In addition, in the existing LED light fixture, the general mode of connecting that adopts connects between each single luminous LED lamp and the LED lamp, but all can obtain higher brightness in order to reach each LED lamp, just need provide higher outer power voltage, not only power consumption is bigger, and can further increase heat that LED produces, and causes the LED lamp pearl life-span to be reduced.And the existing common independent variable-voltage power supply of needs of LED lamp of external power externally fed that needs is powered, and to guarantee the demand of LED lamp to voltage, causes needing extra accessory in the use of LED lamp, makes troubles to use.
In addition, street lamp is in outdoor environment for a long time, requires waterproof and dustproof, protection against insect on the structure, and its lampshade must be the cavity of a sealing.The LED lamp of LED street lamp will be worked in the environment of sealing equally, and this just means that it can't can only outwards dispel the heat by lampshade by cross-ventilation directly to external world's heat radiation.For this reason, can fin be set at substrate back, the heat that the LED lamp is sent in time is dispersed in the air by fin.Limited but the lampshade inner space is sealed, can't form effective convection current, the heat transfer coefficient of air is low again, so existing LED road lamp cooling is slower, can't adapt to the long-term work needs of street lamp.
Summary of the invention
The objective of the invention is to,, provide a kind of LED street lamp, improved the heat-sinking capability of LED street lamp, prolong the working life of LED street lamp at defective of the prior art.
According to purpose of the present invention, a kind of LED street lamp is provided, comprise: lampshade and be placed on paster LED lamp group in the lampshade, described paster LED lamp bond pads is on lamp plate, and described lamp plate comprises successively: the circuit board, heat conducting fiber plate and the thermal conductive metal plate that weld described paster LED lamp.
LED street lamp of the present invention, the heat that sends when by heat conducting fiber plate on the lamp plate and thermal conductive metal plate the paster LED lamp being worked dispels the heat, the heat conducting fiber plate is with the heat transferred thermal conductive metal plate, and thermal conductive metal plate is dispersed into the external world with heat transferred fin or lampshade.LED street lamp of the present invention heat-sinking capability under sealing condition is stronger, prolongs the working life of LED street lamp.

The specific embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
Shown in Fig. 1 a～Fig. 1 e, a kind of LED street lamp embodiment of the present invention comprises: the fuselage 15 of aircraft shape, and fuselage 15 is made up of lampshade 12 and fin 14, and fin 14 is located at the side back to described paster LED lamp; Fuselage 15 inside are heat radiation cavity 13, and lamp plate 11 is placed in the heat radiation unprecedented 13; Fuselage 15 both sides be provided with wing 16, wing 16 is connected with fuselage 15 buckles; Fuselage 15 afterbodys are provided with inserted link 17.
As shown in Figure 2, lamp plate 11 comprises successively: the circuit board 22 of soldering surface mounted LED lamp group 21, heat conducting fiber plate 23 and thermal conductive metal plate 24.The heat transferred thermal conductive metal plate that the heat conducting fiber plate distributes when paster LED lamp group is worked, thermal conductive metal plate is dispersed into the external world with heat transferred fin or lampshade.The LED street lamp of present embodiment heat-sinking capability under sealing condition is stronger, prolongs the working life of LED street lamp.
Preferably, as shown in Figure 3, paster LED lamp group 21 comprises that many groups are fixed in the paster LED lamp on the circuit board, and every group of paster LED light fixture has a plurality of LED coupled in series illuminators, and each is organized between the paster LED lamp and connects by parallel way.Adopt the mode that connection in series-parallel combines in the present embodiment that paster LED lamp group is connected with external power source, compared to existing technologies, in order to reach identical illumination effect, can reduce the voltage of external power source greatly, not only energy-conservation, and the too much heat of LED lamp generation that can avoid too high voltages to bring, thereby the service life of prolongation LED lamp.In the present embodiment, rectification module 32 is a bridge rectifier.
More preferably, paster LED lamp group 21 is connected in series between the both positive and negative polarity of rectification module 32, the input of rectification module 32 and current-limiting resistance 33 are connected in series, and realize that promptly external ac power source elder generation passes through this current-limiting resistance 33, powers to described paster LED lamp group behind rectification module 32 again.As seen, LED street lamp among the present invention can be adjusted the size of current-limiting resistance 33 easily according to paster LED lamp group required voltage, has saved peripheral hardware variable-voltage power supply device needed in the art, make this energy-conservation light fixture to be connected, use more flexible with existing various power supplys.
