The wiring of the substrates leads a power supply line to avoid the complicated arrangement of conducting wires, forms the orderly arrangement, is beautiful and also eliminates the potential safety hazard. When in maintenance, the power supply line which corresponds to a damaged bulb can be fast found; and when in detachment, the plugs can be pulled out of the sockets, and then the substrates are detached, thereby being unnecessary to weld.

Description

The LED street lamp

Technical field

The utility model relates to a kind of lamp, is meant a kind of LED street lamp especially.

Background technology

During the LED operate as normal, need constant voltage or constant electric current to drive (generally all do current constant, be referred to as constant-current source).Existing the most frequently used great power LED operating current is generally 350～700mA, the electric current of constant-current source output must constantly be above-mentioned certain numerical value just like this, and electric current is in a single day constant, and the power of constant-current source also promptly is restricted, and the LED number that can drive also promptly is restricted.Therefore constant-current source LED number that can drive is limited.

In the LED street lamp, generally all be a lot of LED bulbs of assembling, these LED bulbs are pressed the power of constant-current source again, are combined into a plurality of LED lamp groups artificially, and each LED lamp group is all driven by a constant-current source.In the LED street lamp, must comprise a plurality of LED lamp groups and just can reach illumination requirement, so constant-current source also has a plurality of.Existing way is, several LED bulbs are welded on the substrate, with lead constant-current source is connected with electrode on the substrate then, and LED light number is limited by the power of constant-current source; The power supply of constant-current source then is to be connected in the Switching Power Supply output by lead.

A kind of like this shortcoming of element electric connection mode is, LED street lamp inner lead is too much, and disorderly and unsystematic, influences attractive in appearance and has potential safety hazard (LED street lamp work long hours after, internal temperature is too high, makes the wire sheath accelerated ageing, is easy to generate short circuit).In addition, if in a LED lamp group light necrosis is arranged, when keeping in repair, because lead is mixed and disorderly, be not easy to tell the corresponding relation of lead and lamp group, and lead need be welded on other device, in dismounting with all very inconvenient when reinstalling.

The utility model content

It is orderly that technical problem to be solved in the utility model provides a kind of wiring, and not only attractive in appearance but also do not have potential safety hazard, circuit is clear, convenient disassembly, the LED street lamp that need not weld.

In order to address the above problem, the utility model is taked following technical scheme:

A kind of LED street lamp, comprise side by side a plurality of substrates and a plurality of constant flow module, the corresponding constant flow module of each substrate, each constant flow module is arranged at the same end end of counterpart substrate and is fixed on the substrate, at this end of substrate along positive and negative two main power lines are arranged on the substrate vertical direction side by side, on two main power lines, extend two positive and negative plugs respectively with each substrate correspondence position, be welded with two sockets on the both positive and negative polarity of described constant flow module respectively, above-mentioned plug is inserted in respectively in the above-mentioned socket by its polarity.

Preferably, described main power line is that flake conductive material is made, and the outside is coated with insulation sleeve.

Preferably, described plug and main power line are an integral body, and plug is that the end face by the main power line pellet electrode and the plug that extend are exposed outside.

Preferably, described socket one end is welded on the constant flow module, and the other end is the free end of endless belt jack, and the free end of described socket is coated in the insulation sleeve.

The beneficial effects of the utility model are: the wiring of the utility model substrate makes supply line avoid that lead is complicated arranges, and forms orderly arrangement, and is not only attractive in appearance but also do not have a potential safety hazard.During maintenance, can find the supply line of downright bad bulb correspondence very soon; During dismounting plug is extracted in socket, substrate is unloaded get final product then, do not need to weld.

Description of drawings

Fig. 1 is the structure chart of LED street lamp among the embodiment;

Fig. 2 is an A portion enlarged drawing among Fig. 1.

The specific embodiment

For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.

With reference to Fig. 1, a kind of LED street lamp, comprise a plurality of substrates 1 side by side, each substrate 1 corresponding constant flow module 2, each constant flow module 2 is arranged at the same end end of counterpart substrate 1 and is fixed on the substrate 1, along positive and negative two main power lines 3 are arranged on the substrate vertical direction side by side, main power line 3 is connected on the Switching Power Supply at substrate 1 this end, and constant flow module 2 connects the LED lamp.With reference to Fig. 2, on two main power lines 3, extend two positive and negative plugs 5 respectively with each substrate 1 correspondence position, be welded with two sockets 4 on the both positive and negative polarity of described constant flow module 2 respectively, above-mentioned plug 5 is inserted in respectively in the above-mentioned socket 4 by its polarity.Switching Power Supply is connected in the 220V civil power, and Switching Power Supply converts civil power to low-voltage DC and supplies with constant flow module 2, and constant flow module 2 offers the LED lamp with the power supply that this low-voltage DC converts constant current to.Main power line 3 is positioned at end with constant flow module 2, is convenient to connect, and makes wiring in order.

As Fig. 1 and Fig. 2, preferred, described main power line 3 is made for flake conductive material, is generally copper material, and the outside is coated with insulation sleeve, assurance safety.

As Fig. 2, preferred, plug 5 is pellet electrodes that the end face by main power line 3 extends, with the inner core 7 of main power line 3 be an integral body, expose outside the insulation sleeve 6 of main power line 3.Described socket 4 one ends are welded on the constant flow module 2, and the other end is the free end of endless belt jack, and the free end of described socket 4 is coated in the insulation sleeve, and plug 5 is adaptive with socket 4.

Substrate 1 can be the PCB substrate, also can be aluminium base.

During power supply, be powered at two main power lines 3 by Switching Power Supply, conduct to constant flow module 2 by plug 5 and socket 4 then, the LED lamp is given in power supply again.

Advantage is, the wiring on the utility model substrate makes supply line avoid that lead is complicated arranges, and forms orderly arrangement, and is not only attractive in appearance but also do not have a potential safety hazard.During maintenance, can find the supply line of downright bad bulb correspondence very soon; During dismounting plug is extracted in socket, substrate is unloaded get final product then, do not need to weld.

The above only is a preferred implementation of the present utility model.Should be pointed out that for those skilled in the art under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
