Description
Technical field
The utility model relates to LED street lamp technical field, is specifically related to a kind of automatic heat radiation 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 automatic heat radiation 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 automatic heat radiation LED street lamp, comprise the column of hollow, column top is connected with housing, housing bottom is connected with lens, and housing inner bottom part is connected with horizontal pcb board, and pcb board bottom surface is provided with some LED lamp bead, the dividing plate that a cross section is T-shaped is slidably connected in described housing, be connected with magnechuck B in the middle part of dividing plate left end, in the middle part of described inner walls left end, magnechuck A be installed, the housing at the upper and lower two ends of magnechuck A has air admission hole and steam vent; Described column inner top is provided with motor, and the output shaft of motor stretches into housing inner bottom part and motor output shaft end is provided with fan blade.
Distance when the width < dividing plate right-hand member of described air admission hole and steam vent props up inner walls between dividing plate left end and housing left end.
Described dividing plate left side is connected with some horizontal return springs, and the return spring other end is fixed in housing left end inwall.
Described return spring has two and is separately positioned on the upper and lower both sides of dividing plate.
Described pcb board top is provided with radiating fin.
The beneficial effects of the utility model are:
Compared with prior art, the automatic heat radiation LED street lamp that the utility model provides, one piece of dividing plate is set in housing and housing is divided into upper and lower two chambers, upper and lower two chambers are connected by dividing plate right-hand member, during energising, magnechuck drives dividing plate to move to left, air admission hole and steam vent are connected with two chambers up and down in housing respectively, motor-driven fan blade rotary, fresh air sucks from air admission hole, then pcb board is blowed to, finally discharge from steam vent, namely the Air flow path that in housing, formation one is complete, the heat that LED lamp bead sends can be lost rapidly, high temperature is avoided to cause bonding agent actual effect and the luminosity that exists declines, the problem that 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, air admission hole is opened on column and can prevents rainwater from entering the short circuit problem caused in housing, increases the service life of street lamp further.

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 automatic heat radiation LED street lamp that the utility model provides, comprise the column 1 of hollow, column 1 top is connected with housing 2, housing 2 bottom is connected with lens 3, housing 2 inner bottom part is connected with horizontal pcb board 4, pcb board 4 bottom surface is provided with some LED lamp bead 5, the dividing plate 6 that a cross section is T-shaped is slidably connected in described housing 2, magnechuck B14 is connected with in the middle part of dividing plate 6 left end, in the middle part of described housing 2 inwall left end, magnechuck A12 is installed, the housing 2 at the upper and lower two ends of magnechuck A12 has air admission hole 10 and steam vent 13; Described column 1 inner top is provided with motor 9, and the output shaft of motor 9 stretches into housing 2 inner bottom part and motor 9 output shaft end is provided with fan blade 8.
When being in closed condition to prevent dividing plate 6, rainwater enters housing 2, distance when width < dividing plate 6 right-hand member of described air admission hole 10 and steam vent 13 props up housing 2 inwall between dividing plate 6 left end and housing 2 left end.
For the ease of the automatic rebounding of power-off rear bulkhead 6, described dividing plate 6 left side is connected with some horizontal return springs 11, and return spring 11 other end is fixed in housing 2 left end inwall.
In order to ensure elastic force dynamics while improve resilience stationarity, described return spring 11 has two and is separately positioned on dividing plate about 6 both sides.
As shown in Figure 3, in order to improve radiating efficiency further, described pcb board 4 top is provided with radiating fin 7, and this radiating fin is aluminum material.
During work, whole street lamp is all energized, pcb board 14 is energized, LED lamp bead 15 bottom it is luminous, while luminescence, LED lamp bead 15 can produce a large amount of heats, magnechuck A12 and magnechuck B14 produces suction mutually, suction drives magnechuck B14 to move to magnechuck A12, and then drive dividing plate 6 to slide left, when magnechuck A12 and magnechuck B14 is adjacent in state as shown in Figure 2, now dividing plate 6 is in high order end, air admission hole 10 and steam vent 13 all with housing 2 inner space, the motor 9 drive fan blade 8 that is energized rotates, air in housing 2 is discharged from steam vent 13 by the rotation of fan blade 8, negative pressure state is formed in housing 2, fresh air enters in housing 2 from air admission hole 10, on final formation air admission hole 10 → housing 2 → the such cooling channel of housing 2 lower floors → radiating fin 7 → steam vent 13, effectively can reduce the temperature of housing 2, ensure the normal work of LED lamp bead 5.
