Abstract
The utility model discloses a kind of LED street lamp, comprise housing, in housing, bottom is provided with lens, the pcb board of band LED lamp bead is also installed in housing, described housing tip both sides are all hinged with baffle plate by rotating shaft, baffle plate end is embedded with magnechuck A, and bottom, described housing both sides all estimates at the magnechuck B matched with magnechuck A; Pcb board both sides housing bottom all has pore, is all provided with fan in pore.The utility model can form cooling channel in housing, effectively reduces the temperature in housing, ensures the normal illumination work of LED.
Description
Technical field
The utility model relates to LED street lamp technical field, is specifically related to a kind of LED street lamp.
Background technology
The solid-state semiconductor devices of LED to be a kind of can be by electric energy conversion visible ray, general Chinese is translated into light emitting diode, and it directly can be converted into light electricity.The operating voltage of LED is very low (more several volts had); Operating current very little (the only zero point several milliamperes had can be luminous); Shock resistance and anti-seismic performance good, reliability is high, and the life-span is long, nowadays generally uses it as illumination in all trades and professions.
In order to respond the call of the energy-saving and emission-reduction of country, a lot of street lamp all adopts LED as light emitting source at present, it has the advantages such as energy consumption is low, volume is little, luminous quantity is large, but also there is the large problem of caloric value simultaneously, LED lamp bead is all closed and is arranged in the housing of shell street lamp, its heat sent slowly can only be distributed by housing, the lost efficiency of obvious heat is extremely low, if the temperature in housing is too high, easily cause the actual effect of the materials such as bonded adhesives, the easy problem that comes off, causes part LED cannot normally to work luminescence, reduces illuminating effect; And temperature is too high also can there is disaster hidden-trouble, if accidentally there is fire accident, there is larger potential safety hazard, and just again must change whole street lamp assembly once on fire, cost is very high.
Utility model content
The utility model aims to provide a kind of LED street lamp, with solve traditional LED street lamp cannot quick heat radiating cause LED lamp bead comes off, luminosity weakens, illuminating effect is poor, fragile, easy spontaneous combustion, problem that replacement cost is high.
The utility model is achieved by following technical solution:
A kind of LED street lamp, comprise housing, in housing, bottom is provided with lens, the pcb board of band LED lamp bead is also installed in housing, described housing tip both sides are all hinged with baffle plate by rotating shaft, baffle plate end is embedded with magnechuck A, and bottom, described housing both sides all estimates at the magnechuck B matched with magnechuck A; Pcb board both sides housing bottom all has pore, is all provided with fan in pore.
The hinged end of described baffle plate and housing is provided with torsional spring.
The thickness of the length >=housing of described baffle plate.
Described pcb board top is provided with radiating fin.
The beneficial effects of the utility model are:
Compared with prior art, the LED street lamp that the utility model provides, all baffle plate is hinged with in housing both sides, baffle plate drives closed by magnechuck, in deployed condition under the effect that during conventional sense, baffle plate is paralysed in the rotation of its hinged end, the heat that LED lamp bead sends can lose rapidly by fan, avoids high temperature to cause bonding agent actual effect and problem, the problem includes: the problem that luminosity declines, illuminating effect weakens; And scattering and disappearing fast of heat can also be avoided, in housing, pyrophoricity accident occurs, can effectively improve service life of the present utility model, without the need to often changing parts, maintenance cost effectively reduces; In addition, baffle plate can also prevent rainwater from entering the short circuit problem caused in housing, increases the service life of street lamp further.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the sectional view of radiating fin in the utility model;
In figure: 1-housing, 2-baffle plate, 3-radiating fin, 4-fan, 5-PCB plate, 6-lens, 7-LED lamp pearl, 8-magnechuck A, 9-magnechuck B, 10-rotating shaft.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but described in required protection domain is not limited to;
As shown in Figure 1, the LED street lamp that the utility model provides, comprise housing 1, in housing 1, bottom is provided with lens 6, the pcb board 5 of band LED lamp bead 7 is also installed in housing 1, both sides, described housing 1 top are all hinged with baffle plate 2 by rotating shaft 10, and baffle plate 2 end is embedded with magnechuck A8, and bottom, described housing 1 both sides all estimates at the magnechuck B9 matched with magnechuck A8; All have pore 11 bottom pcb board 5 liang of side bodies 1, in pore 11, fan 4 is all installed.
In order to ensure that baffle plate 2 is in deployed condition, accelerating the amount of flow of air, improving radiating effect, described baffle plate 2 is provided with torsional spring with the hinged end of housing 1.
The thickness of the length >=housing 1 of described baffle plate 2, it can play the effect of awning, avoids rainwater to enter housing 1 and causes short circuit.
As shown in Figure 2, in order to improve radiating efficiency further, described pcb board 14 top is provided with radiating fin 13, and this radiating fin is aluminum material.
During work, pcb board 5 is energized, LED lamp bead 7 bottom it is luminous, while luminescence, LED lamp bead 7 can produce a large amount of heats, and now two fans 4 in left and right switch on power and start working and rotating Vortex, and air enters in housing 1 from a pore 11, discharge from another pore 10 again, form the flowing of air and then the heat loss that LED lamp bead 7 produces is fallen, effectively can reduce the temperature in housing 1, ensureing the normal work of LED lamp bead 7.
When raining, or winter temperature lower time, magnechuck A8 and magnechuck B9 is energized simultaneously, produce attraction between magnechuck A8 and magnechuck B9, drive baffle plate 2 to move to housing 1 side, baffle plate 2 is 10 rotations around the shaft, after magnechuck A8 and magnechuck B9 fits, finally complete the withdrawal of baffle plate 2, now the air inflow of pore 11 and capacity reduce, and rainwater etc. can be avoided to enter in housing 1, effectively can increase service life.
