In the electricity usage structure in the whole world, electric consumption on lighting accounts for 19% of total electricity consumption.In recent years, take measures to reduce the CO2 discharge capacity with the proposal sound that prevents greenhouse effects in, the cry that requires to reduce the lighting power consumption also grows to even greater heights.Be subjected to the promotion of this strength just, each relevant manufacturer is carrying out the R﹠D work of efficient illumination light fixture at present.Towards key lighting market, power conversion efficiency has improved 10%～20% fluorescent lamp goes on the market, and, mainly use the lamp affixed to the ceiling of incandescent lamp also to be replaced by efficient more and more in the past and exceeded 4-5 bulb type fluorescence lamp doubly.Along with the continuous development of light emitting diode (LED) lighting engineering, mainly be the increase of its power, the raising of efficient, the decline of cost is more and more adopted by all kinds of illuminating engineering.LED is not only in the decorative lighting field, and also occupies a tiny space at functional lighting field.As signal lamp, automobile tail light, waterproof anti-explosion type torch, comprise a part of room lighting and road lighting.LED is as a kind of solid light source, with its long-life, high light efficiency, how photochromic and once light-distribution directional illumination function, can under the safety low-voltage, work, also switch dodges disconnected continuously, can easily realize many advantages such as 0～100% dimming function, become the development trend of light source of new generation.Though the cost of LED light emitting diode is in continuous reduction, but because the use that is applied in now in the street lamp all is to adopt integrally-built LED light emitting diode lamp plate as light source, if producing, damages this situation sub-fraction LED luminous earphone pipe wherein, cause brightness of illumination not enough, just need all to change whole lamp plate, the waste that this phenomenon caused is very serious, has also increased the cost of operation and maintenance simultaneously; Also there is an other shortcoming in the frame mode of this whole lamp plate in addition, is exactly the street lamp of a different size of every making, all needs die sinking again to make the lamp plate of a new spec, and this frame mode has caused the rising of production development cost naturally.
[summary of the invention]
The purpose of this utility model provides and is used to make up the LED lamp module that street lamp uses, and this module has simple in structure, the characteristics of perfect heat-dissipating.
In order to realize above-mentioned technical purpose, the technical solution that the utility model adopts comprises following technology contents: a kind of LED energy-conserving road lamp module, it is characterized in that: described led module is made of at least more than one the LED lamp that is arranged on the circuit board, this circuit board back fixation has heat-dissipating fin, this heat-dissipating fin is made up of installation base plate and the heat radiation wing that is fixed on the above-mentioned installation base plate, described installation base plate back is provided with groove, heat radiation wing bottom is provided with fin, groove on the above-mentioned installation base plate and the fin of heat radiation on the wing composition heat-dissipating fin that cooperatively interacts, circuit board and heat-dissipating fin are fixed as one.
Described circuit board is aluminum or copper substrate, and the line layer of control circuit is arranged in the insulating barrier and sticks on the substrate on the circuit board.
Described heat radiation wing is thorn-like and is arranged on the installation base plate, and the cross section of this heat radiation wing is " rich " word, " king " word or " worker " shape.
Described heat radiation wing is fixed on the installation base plate by screw by being arranged on the through hole at its two ends, adopts the mode of welding to make the said two devices fusion for whole simultaneously.
Be coated with anti-corrosion metal material on the described heat radiation wing.
By adopting above-mentioned technical solution, the utility model has obtained following technological merit and effect: at first the utility model is crossed and is adopted modular mentality of designing, having changed in the existing LED street lamp industry every kind of street lamp all needs to offer separately the way of mould, realized using one or several modules to make up, the LED energy-conserving road lamp of production plurality of specifications and power requirement, this mode can be accelerated the research and development of products cycle, significantly reduces production costs simultaneously; By on module, adopting the circuit board of aluminum, significantly promoted the capacity of heat transmission of foregoing circuit plate in addition, in the structure that is used the heat-dissipating fin that closely links together with this circuit board, the very effective problem of improving the great power LED heating; By adopting by installation base plate and the branch body structure that is fixed on the heat radiation wing on the installation base plate, simplified the production cost of heat-dissipating fin, cooperate simultaneously and adopt the structure that on installation base plate and heat radiation wing, adopts groove and fin to cooperatively interact, make said two devices have bonding strength very reliably, the structure that adopts the mode of welding that said two devices is fixed as one again, further improve the intensity that connects, improved heat dispersion simultaneously; And be coated with anti-corrosion metal material in the heat-dissipating fin outside, and for example: chromium, nickel etc., improved the antiseptic property of heat-dissipating fin, guaranteed that heat-dissipating fin is in the reliability of outside work for a long time.
In a word, this use is novel to provide a kind of low production cost by above-mentioned a series of architecture advances, and Novel LED street lamp that can flexible combination, has effectively solved the bad problem of LED road lamp cooling performance.This street lamp has long service life, reliability height and a kind of easily novel energy-saving road lamp easy to maintenance.
