Abstract
Provided is a multi-loop LED street lamp capable of reducing light attenuation and prolonging a service life; the multi-loop LED street lamp comprises a lamp body; lamp beads are fixedly arranged inside the lamp body; the lamp beads are arranged in parallel inside the lamp body in a multi-loop manner; a thermal sensor and a control device are arranged inside the lamp body; the thermal sensor and the control device are connected through a cable. The loops of the lamp beads are a three-way loop, a four-way loop and a five-way loop. The multi-loop LED street lamp of the utility model is advantaged in that: according to the multi-loop LED road lamp of the utility model, when the temperature of LED lamp beads of one loop reaches a set temperature, the thermal sensor can send signals to a control system; the control system cuts off the electricity to extinguish the lamp beads and turns on standby lamp beads of a nearest loop; a junction temperature of the extinguished lamp beads of the loop will not continue to rise; under the effect of a radiator, the junction temperature is reduced to a proper working temperature; and therefore, life service of the LED street lamp can be prolonged, and the influence of the temperature on the light attenuation of the LED street lamp can be effectively alleviated.
Description
Technical field
The utility model relates to a kind of LED lamp, relates in particular to a kind of multiloop LED street lamp that can prolong its useful life.
Background technology
LED light fixture light decay is meant LED after lighting after a while, and its light intensity can be lower than original light intensity, and low part is exactly the light decay of LED street lamp.The light decay of LED light fixture product is exactly that the signal of light in transmission weakens, and the LED light fixture product light decay degree that the big factories of global LED of present stage make is all different, and there is the very serious problem of light decay equally in high-power LED lamp, and the reason of its light decay is following:
1, the LED street lamp is a constant-current driving, has partial L ED to adopt voltage and current drives reason to cause LED street lamp light decay.
2.LED the thermal resistance of the elementary cell LED lamp pearl chip of road-light light-source itself, the influence of elargol, the radiating effect of substrate and the light decay that aspects such as colloid and gold thread cause.
3. most of White LEDs are obtained by blue led irradiation fluorescent material.The main cause that causes the LED light decay has two, and one is the light decay of blue-ray LED itself, and the light decay of blue-ray LED wants fast more than ruddiness, gold-tinted, green light LED.Also having one is the light decay of fluorescent material, and fluorescent material decay at high temperature is very serious.
Summary of the invention
The purpose of the utility model provides and a kind ofly can reduce light decay, the multiloop LED street lamp that prolongs its useful life.
For realizing above-mentioned purpose, the technical scheme that the utility model adopted is:
A kind of multiloop LED street lamp; Comprising: lamp body; The lamp body internal fixation is equipped with the lamp pearl, and its characteristics are: described lamp pearl is that multiloop is in parallel installed with in lamp body, also is designed with heat-sensitive sensor in the described lamp body; Also be designed with control device in the described lamp body, heat-sensitive sensor is connected through cable with control device.
According to above-mentioned multiloop LED street lamp, its characteristics are: the loop of described lamp pearl is three the tunnel, the four tunnel, the five tunnel.
The utility model has the advantages that: in the utility model, when one road led lamp pearl arrives the temperature of setting, will pass to control system to signal through heat-sensitive sensor, control system is cut off the power supply to it and is extinguished, and lights its road nearest stand-by lamp pearl.A street lamp pearl junction temperature of extinguishing just can not continue to raise; Under the effect of radiator, make its junction temperature be reduced to suitable working temperature, wait quilt is next time lighted; So recycle; Neither can influence road lighting to brightness requirement, can prolong the led street lamp life-span again, effectively improve the problem of temperature the light decay of led light fixture.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.
A kind of multiloop LED street lamp; As shown in Figure 1, comprising: lamp body 1, lamp body 1 internal fixation is equipped with lamp pearl 2; Lamp pearl 2 is in parallel installed with in lamp body 1 for multiloop; Also be designed with heat-sensitive sensor 3 in the described lamp body 1, also be designed with control device 4 in the described lamp body 1, heat-sensitive sensor 3 and control device 4 are connected through cable.
In the present embodiment, the loop of lamp pearl 2 is three the tunnel, the four tunnel, the five tunnel.
The beneficial effect of the utility model is: the utility model has effectively solved the junction temperature problem of the elementary cell LED lamp pearl of LED street lamp.Particularly solving the LED street lamp gathers in those led light source junction temperature height of centre and the problem of temperature stack.Through the control mode of multiloop parallel connection is set, under the effect of radiator, make its junction temperature be reduced to suitable working temperature.
Embodiment recited above describes the preferred implementation of the utility model; Be not that design and protection range to the utility model limits; Under the prerequisite that does not break away from the utility model design concept; Common engineers and technicians make the technical scheme of the utility model in this area various modification and improvement all should fall into the protection range of the utility model.
