LED illumination is considered to the new energy-conserving light source of illumination of 21 century, because under same brightness, LED lamp power consumption is only 1/10 of ordinary incandescent lamp, 1/2 of fluorescent tube, LED lamp is not only energy-conservation, also has that the life-span is long, volume is little, safety, environmental protection, a feature such as non-maintaining, easy to control.LED lamp, as novel illumination light source, has the very big potentiality of alternative traditional lighting light source.Therefore, research and development high-tech, high efficiency, LED light fixture cheaply, make it, in more traditional lighting field alternate application, to have extremely important realistic meaning.

Great power LED is a direction of LED industry future development, but great power LED has relatively high expectations to heat dissipation technology, and the power of LED module is larger, and the heat flow density of its chip is just higher.When the effect of radiator is bad, the temperature of LED chip sharply rises, and can produce very soon light decay, even damages LED chip.Only have the heat dissipation technology that solves great power LED, delay to greatest extent the light decay of LED, could promote widely the application of great power LED.

At present, the radiator structure of high-power LED street lamp, Tunnel Lamp and Projecting Lamp, adopts die-casting die LED module and plate shaped extrusion section bar electronic heat sink or hot pipe technique mostly.Adopt the light fixture of plate shaped extrusion section bar, by many great power LEDs, formed, at the central hot of its radiator, concentrate, unbalanced to the heat radiation of great power LED, and cause the great power LED in centre to produce light decay, shorten luminescent lifetime.In addition, adopted great power LED that lighting angle is little and secondary lens and produced dazzle, the arrangement of great power LED is more concentrated again, can not meet the needed distribution curve flux in various places.Adopt hot pipe technique cost high, easy dust stratification dirt in fin, the necessary larger shell of overcoat, therefore affects whole radiating effect.

Summary of the invention

For solving the radiator structure of high-power LED street lamp, Tunnel Lamp, Projecting Lamp and meeting needed distribution curve flux, the utility model provides a kind of LED module street lamp of ventiation type heat radiation.

The utility model solves the technical scheme that its technical problem adopts: comprise metal framework, LED module, power pack, LED driving power and LED aluminium base, during for semiconductor lighting, the LED aluminium base that is welded with some LED lamps is fixed on above the substrate of LED module, and described LED module consists of substrate, LED aluminium base, fixed mount, fin and fin.

On four angles of described substrate, be provided with fixed mount, and be provided with several fins on two sides of fixed mount, on its end, have fixing hole.

On four sides of described substrate, be provided with fin, on substrate both sides, be provided with several fins, and arrange uniformly in the mode of being separated by with fin.

The center of described substrate has the fairlead penetrating, and the lead-in wire of LED driving power is electrically connected to the fairlead through in this substrate with LED aluminium base.

As a kind of preferred structure, several LED modules are assembled and be fixed on above metal framework and form LED module street lamp.

Described power pack bottom surface has ventilating opening, in its inside, LED driving power is housed, and with bolt, fixed head is anchored on above power pack.

The lead-in wire of above-described LED driving power is electrically connected to the fairlead through in substrate with LED aluminium base.

The beneficial effects of the utility model are, owing to adopting modularization ventiation type radiator structure, the convection current air of LED module is directly through substrate fin and fin around, greatly improve the radiating effect of substrate, and the transmission of LED aluminium base heat has been accelerated to speed, reduce to greatest extent the light decay of great power LED, guarantee that great power LED is used long-life object, the length shape luminous intensity distribution that light is evenly distributed be can realize simultaneously and street lamp or the required light distribution requirements of Tunnel Lamp met, the maintenance of very convenient driving power and replacing, thereby make high-powerly to there is outdoor LED lighting good luminous intensity distribution and radiating effect and easy to maintenance and become possibility.
