Description
Technical field
The utility model relates to LED street lamp technical field, is specifically related to a kind of LED street lamp of energy high efficiency and heat radiation.
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 aim to provide a kind of can the LED street lamp of high efficiency and heat radiation, 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 of energy high efficiency and heat radiation, comprise the column of hollow, column top is connected with coupled logical housing, and housing bottom is connected with lens, is connected with horizontal pcb board in housing, pcb board bottom surface is provided with some LED lamp bead, be provided with a horizontal dividing plate in described housing, dividing plate right-hand member and housing Joint, housing end face is provided with a sleeve parallel with dividing plate with between dividing plate by pillar, be fitted with a rotating shaft in sleeve, rotating shaft two ends are connected with fan blade and driving wheel respectively; Described housing tip is connected with motor cover, is provided with motor in motor cover, and the output shaft of motor is connected with driving wheel, and driving wheel and driving wheel match; Described column has some air admission holes, and described housing right-hand member bottom has some steam vents.
Described driving wheel is connected by belt or chain with between driving wheel.
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 of the energy high efficiency and heat radiation 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 left end, motor gets final product drive fan blade rotary, fresh air can enter from the air admission hole column, then pcb board is blowed to, finally discharge from the steam vent housing, and the Air flow loop 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.
