Description

A kind of high-heat-dispersion LED street lamp
Technical field
The utility model relates to the LED field, is specifically related to a kind of high-heat-dispersion LED street lamp.
Background technology
LED is a kind of new type light source, compares with traditional lighting source, and it has energy-conservation, low pressure, volume is little and advantage such as environmental protection, and rated current is that tens milliamperes LED is called low-power LED, and specified LED more than or equal to 350 milliamperes is called great power LED.Compare with low-power LED, single brightness of great power LED has improved tens of times.And along with the increase of Light-Emitting Diode brightness and the reduction of manufacturing cost, great power LED is more and more in the use of various lighting fields, replaces the main flow incandescent lamp bulb and the fluorescent lamp of present illumination market probably.
Compare with conventional road lamp, the LED street lamp not only has advantages such as environmental protection and energy saving, and more important is long, non-maintaining advantage of life-span, because the common height of street lamp is hung on the lamp stand, the life-span is long, non-maintaining just to seem particularly outstanding in street lamp application.But, for the industrialization of LED street lamp, heat radiation is a maximum difficult problem, also has to adopt common lamp body to add fan to dispel the heat and make the LED street lamp, but owing to install complicated, structure is scattered, so that is difficult to popularize, and, fan power consumption itself is on the one hand, the life-span that the most important thing is fan is very short, often needs to safeguard that this just makes the advantage of LED lamp be not in full use.Search to the bottom, the key of LED road lamp cooling is the Installation Modes of led light source and heat-radiating substrate, traditional form is: two electrodes that led light source is drawn by the lower end are connected with pcb board, obtain power supply from pcb board on the one hand, on the other hand by thermo-contact, led light source conducts to the LCB plate with heat, to realize heat radiation, but because the contact-making surface of two electrodes and pcb board is limited, so that heat-transfer rate is too small, when led light source worked long hours, the heat that is produced can not in time be derived, thereby made led light source xanthochromia occur or fault such as burn.
For traditional integral LED street lamp, its maintenance work complexity influences the work of LED street lamp even because maintenance time is oversize.And, at outdoor maintenance cost height not only, and being subjected to the restriction of factors such as weather, inconvenience operates.In fact, the fault of LED street lamp, majority is because of bad the causing of led chip heat radiation.
On the other hand, influence the water resistance that LED street lamp operate as normal factor also is street lamp, traditional LED street lamp is realized waterproof by design of Sealing Structure usually, but existing waterproof construction defective is still many, as long as concentrate on light fixture waterproof (waterproof of led light source, pcb board), be badly in need of proposing a kind of new waterproof scheme.
On the one hand, influence LED street lamp operate as normal, what often ignore in existing a bit is exactly installing and fixing of lamp body, loosening between lamp body and the lamp stand as if frequent, or cause LED street lighting angle deviating, more seriously cause coming off of lamp body, these all are the existing existing critical defects of LED street lamp.
