Abstract
A high-power integrated LED street lamp comprises the following components: a lamp stand, a lamp socket provided at the top of the lamp stand, a large-power integrated LED lamp provided at a lamp base, and a power supply which supplies power to the large-power integrated LED lamp. The power supply comprises a constant-voltage power supply and a constant-current driving circuit. The large-power integrated LED lamp is formed through integrating a plurality of groups of LED lamps. The number of the constant-current driving circuit is corresponding with the number of the integrated groups of LED lamps. Each integrated group of LED lamp is connected with a corresponding constant-current driving circuit. The constant-voltage power supply is provided at the base of the lamp stand and is connected with a plurality of parallelly connected constant-current driving circuits through power lines. Compared with the prior art, the high-power integrated LED street lamp has the following advantages: convenient power supply maintenance, low maintenance cost, and luminescence consistency of each integrated group of LED.
Description
Technical field:
The utility model relates to a kind of street lamp.
Background technology:
Existing high-power integrated LED street lamp, generally all be by lamp stand, be arranged on the lamp stand top lamp socket, be arranged on high-power integrated LED lamp on the lamp socket, constitute to the power supply of high-power integrated LED lamp power supply, what power supply adopted all is constant voltage source.Be subjected to the characteristic of LED lamp to determine that constant voltage source all is arranged in the lamp socket,, avoid of the influence of the resistance of power line self, to guarantee the stability of power supply to the stability of powering so that shorten the power line between constant voltage source and LED lamp as much as possible.This kind high-power integrated LED street lamp, there is following shortcoming: 1, because constant voltage source is the parts that a kind of ratio is easier to damage, in case damage, just need carry out maintain and replace to constant voltage source by the top to lamp stand on the climbing instrument, one has increased the difficulty and the cost of maintenance, has also seriously influenced the current of road simultaneously; 2, constitute for integrated group by a lot of groups of LED owing to high-power integrated LED lamp, and integrated group of every group of LED is made of a lot of LED lamps, and the resistance of each LED lamp is different, and what resistance was little must divide the electric current that flows through just big, brightness is just big, makes integrated group of each LED luminous inconsistent.
Summary of the invention:
Goal of the invention of the present utility model is to provide that a kind of power supply is easy to maintenance, maintenance cost is low, the high-power integrated LED street lamp of integrated group of luminous unanimity of each LED.
The utility model is to realize like this, comprise lamp stand, be arranged on the lamp stand top lamp socket, be arranged on high-power integrated LED lamp on the lamp socket, to the power supply of high-power integrated LED lamp power supply, power supply comprises constant voltage source, constant-current drive circuit, high-power integrated LED lamp is made of for integrated group array LED lamp, the quantity of constant-current drive circuit is corresponding with the quantity of integrated group of LED lamp, integrated group of each LED lamp is connected with corresponding constant-current drive circuit, and constant voltage source is arranged on the bottom of lamp stand and is connected with several constant-current drive circuits in parallel by power line.During work, if the high-power integrated LED lamp that is adopted is integrated group of four and 7 string LED lamps, overhead 10 meters of lamp sockets, the working voltage that constitutes the LED lamp pearl of integrated group of LED lamp is 3.25V, the total LED conduction voltage drop of 7 strings is 3.25X7=22.75V just so, be the constant-current drive circuit output voltage by the LED clamper at 22.75V, the LED that promptly constitutes constant-current drive circuit drives the output voltage of chip correspondence about 22.75V, because IC dutycycle problem, the input voltage of constant-current drive circuit is wanted (its voltage of different IC is different) between the high 3-5V of specific output voltage, the constant current effect can be relatively good, if 10 meters height, output to the constant-current drive circuit input from constant voltage source the pressure drop of any is arranged, if pressure drop is 2V, then the voltage of power supply output is 22.7V+ (3-5) v+2=27.7-29.7V, so can set the constant voltage source output voltage is set to about 29V, thereby guarantee the operate as normal of high-power integrated LED lamp, adopt constant-current drive circuit, make every group the supply current of integrated group of LED lamp identical, make the brightness of integrated group of LED lamp of each group identical, relatively easy out of order constant voltage source is arranged on the bottom of lamp stand, to be not easy to be out of order, the constant-current drive circuit that reliability is high is arranged on the lamp socket, both made power supply easy to maintenance, maintenance cost is low, can not influence the operate as normal of street lamp simultaneously again.
Compared with the prior art the utility model has that power supply is easy to maintenance, maintenance cost is low, the advantage of integrated group of luminous unanimity of each LED.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the circuit diagram of the utility model power supply.
The specific embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in the figure, the utility model comprises lamp stand 1, be arranged on the lamp socket 2 on lamp stand 1 top, be arranged on the high-power integrated LED lamp 3 on the lamp socket 2, power supply to high-power integrated LED lamp 3 power supplies, power supply comprises constant voltage source 4, constant-current drive circuit 5, high-power integrated LED lamp 3 is made of integrated group of 3a of array LED lamp, the quantity of constant-current drive circuit 5 is corresponding with the quantity of integrated group of 3a of LED lamp, integrated group of 3a of each LED lamp is connected with corresponding constant-current drive circuit 5, and constant voltage source 4 is arranged on the bottom of lamp stand 1 and is connected with several constant-current drive circuits 5 in parallel by power line 6.
