A kind of Modular LED street lamp
Technical field
The utility model relates to a kind of Modular LED street lamp.
Background technology
LED is as a kind of novel illumination light source, and with its long-life, high light efficiency, how photochromic and once light-distribution directional illumination function, the many advantages such as can work under safe voltage becomes the development trend of light source of new generation.Based on above-mentioned advantage, existing street lamp has adopted led light source as lighting source in a large number.But street lamp needs the illumination of high brightness usually, so need the led light source of configuration relatively high power, because high-power LED chip caloric value is excessive and concentrated, present common street lamp adopts a plurality of led chips to throw light on, and a plurality of led chips in the street lamp normally are soldered on the same substrate, when certain or a plurality of led chips break down, need whole street lamp to change, safeguard that inconvenience and maintenance cost are high.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of Modular LED street lamp, have easy to maintenance, maintenance cost is low, the characteristics of good heat dissipation effect.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of Modular LED street lamp, comprise the street lamp main body, it is characterized in that described street lamp main body comprises lamp bracket, power supply module and is arranged on light source assembly on the lamp bracket, LED module group unit separate and that be connected with power supply module respectively forms described light source assembly by at least two groups.
Described LED module group unit is provided with five groups.
Described LED module group unit comprises radiator, be arranged on the substrate on the radiator and be arranged on some led chips on the substrate.
Described LED module group unit also disposes the lens board corresponding with led chip.
Offer a through wires hole on the described radiator, and this through wires hole disposes a water joint, the wire of described power supply module by water joint pass behind the through wires hole be arranged on substrate on led chip be connected.
Described power supply module is arranged on a side of lamp bracket inside, and described lamp bracket disposes the bonnet corresponding with power supply module.
Offer some louvres on the described bonnet.
Described power supply module also disposes a terminal box, and described set of terminal box is in lamp bracket.
Be provided with a mount pad on the described lamp bracket.
The beneficial effects of the utility model are: LED module group unit separate and that be connected with power supply module respectively forms the light source assembly of LED street lamp by at least two groups, every group of LED module group unit forms by a plurality of led chips, because each LED module group unit is independently-powered, and mutually noninterfere, when certain or a plurality of led chips on the LED module group unit break down, do not affect the illumination of other LED module group units, only need change or keep in repair corresponding LED module group unit when safeguarding gets final product, need not to change whole street lamp, easy to maintenance, the cost of maintenance is low; In addition, every group LED module group unit all disposes independently radiator, improves whole road lamp cooling effect.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is decomposing schematic representation of the present utility model;
Fig. 3 is the decomposing schematic representation of the utility model LED module group unit.
The specific embodiment
Referring to figs. 1 through Fig. 3, Fig. 1 to Fig. 3 is the structural representation of a specific embodiment of the utility model, as shown in the figure, a kind of Modular LED street lamp, comprise street lamp main body 1, this street lamp main body 1 comprises lamp bracket 9, power supply module 8 and be arranged on light source assembly on the lamp bracket 9, be provided with a mount pad 92 in the side of lamp bracket 9, street lamp main body 1 is mounted on the pillar of street lamp by this mount pad 92, LED module group unit 2 separate and that be connected with power supply module 8 respectively forms the light source assembly of street lamp by five groups, LED module group unit 2 is threaded connection and is installed on the lamp bracket 9, it comprises radiator 21, be arranged on the substrate 22 on the radiator 21 and be arranged on some led chips 23 on the substrate 22, because each LED module group unit 2 is independently-powered, and mutually noninterfere, when certain or a plurality of led chips 23 on the LED module group unit 2 break down, do not affect the illumination of other LED module group units, only need change or keep in repair corresponding LED module group unit 2 when safeguarding gets final product, need not to change whole street lamp, easy to maintenance, the cost of maintenance is low.
Further, as shown in the figure, LED module group unit 2 also disposes the lens board 24 corresponding with led chip 23, lens board 24 can be adjusted the irradiating angle of led chip 23, so that LED street lamp road pavement has preferably irradiation brightness and angle, wherein offer a through wires hole 212 on the radiator 21, and this through wires hole 212 disposes a water joint 211, power supply module 8 also disposes a terminal box 81, the outlet line of power supply module 8 all is connected to terminal box 81, distribute output by terminal box 81 again, output lead passes behind the through wires hole 212 led chip 23 connections on the substrate 22 with corresponding LED module group unit 2 by water joint 211, terminal box 81 is one to seal preferably box body, water resistance is better, and wire is connected by water joint 211 with LED module group unit 2, so that whole LED street lamp has preferably water resistance, is suitable for using as outdoor road lamp.
In addition, every group of LED module group unit 2 all disposes independently radiator 21, good heat dissipation effect, and lamp bracket 9 disposes the bonnet 91 corresponding with power supply module 8, offer some louvres 911 on this bonnet 91, so that have preferably cross-ventilation effect in the street lamp main body 1, improve the radiating efficiency of LED street lamp, good heat dissipation effect.
More than better enforcement of the present utility model is specified, certainly, the utility model can also adopt form different from the embodiment described above, for example: LED module group unit 2 can be set to two groups or many groups as required; So those of ordinary skill in the art should belong in the protection domain of the present utility model the conversion that is equal to of doing under the prerequisite of spirit of the present invention or corresponding the change.
