Abstract
The utility model discloses a high-power LED street lamp fitting, belonging to the technical field of luminaire. The high-power LED street lamp fitting comprises a shell; a relatively sealed cavity isarranged in the shell; a driver is arranged in the cavity; at least one lens is arranged at the lower side of the cavity; a high-power LED lamp electrically connected with the driver is arranged at the upper side of the lens in the cavity; convection holes running through the shell from top to bottom are arranged on the shell at two sides of the cavity; and a plurality of heat dissipation grids are arranged at the periphery of the shell. The high-power LED street lamp fitting is good in heat dissipation and enables the high-power LED lamp to work constantly under temperature with high lighting effect. The high-power LED street lamp fitting is suitable for big places requiring illumination, like streets, stadiums, airports and docks.
Description
Technical field
The utility model relates to a kind of road lamp, particularly a kind of LED road lamp.
Background technology
The LED light fixture has long-life, high light efficiency, low power consumption, anti-vibration, short, free of contamination advantage of response time, and as a kind of energy-conservation electric light source products, it is used more and more widely; Along with development of technology, its color change is also more and more abundanter, makes it not only can be used as ornamental light source, can also be used for illumination.Existing illuminating LED lamp, general power is lower, is suitable for less illumination place, space, for bigger places, space such as road, bridge, stadiums, harbours, then need to adopt more high-power LED lamp, could satisfy the illumination needs, along with the increase of power, the caloric value of LED lamp and driver thereof is also big, the light efficiency of LED can descend along with the rising of temperature, service life also can Yin Gaowen and shorten, and therefore, heat dissipation problem is to solve the importance that great power LED is applied.
The utility model content
The purpose of this utility model provides a kind of high-power LED street lamp fixture, makes it have better heat radiating effect, can keep the high light efficiency of LED lamp.
The purpose of this utility model is achieved in that high-power LED street lamp fixture, comprise housing, be provided with airtight relatively cavity in the housing, be provided with driver in the cavity, the downside of cavity is provided with at least one lens, is positioned at the lens upside in the cavity and is provided with high-powered LED lamp, and the LED lamp is connected with actuator electrical, the housing of cavity both sides be provided with run through up and down housing to discharge orifice, the housing periphery is provided with some heat radiation grids.
During the utility model work, the LED lamp gets electroluminescence, scioptics are outwards dispersed, illumination is provided, and the power of LED lamp can reach more than the 100W, and the road lighting of enough brightness can be provided, the heating of driver and LED lamp can outwards be scattered and disappeared by the grid on the housing, the housing area of dissipation is big, and grid makes area of dissipation further enlarge, and can improve radiating effect; Discharge orifice is arranged so that the rising of being heated of air-flow with the cavity contact portion, to continuous additional the entering of rising of the cold air of discharge orifice bottom to discharge orifice, form good heat convection, like this, the heating of driver and LED lamp can in time be led away, makes high-power LED lamp can always work under the temperature of high light efficiency.The utility model can be used for bigger illumination place, space, as road, stadiums, airport, harbour etc.
Make simply for making, heat radiation is good, and described housing and heat radiation grid are by the aluminium die cast.Aluminium has good heat-conducting, and its ductility is good simultaneously, is convenient to die cast.
Description of drawings
Fig. 1 is the utility model vertical view.
Fig. 2 is the utility model front view.
Fig. 3 is the utility model upward view.
Wherein, 1 driver, 2 housings, 3 pairs of discharge orifices, 4 grids.
The specific embodiment
As figure, be the high-power LED road lamp, it mainly includes housing 2, be provided with airtight relatively cavity in the housing 2, be provided with driver 1 in the cavity, the downside of cavity is provided with three lens 5, be positioned at lens 5 upside correspondences in the cavity and be provided with three groups of high-powered LED lamps, the power of each group LED lamp can reach 100w, each LED of family lamp is electrically connected with driver 1, the housing of cavity both sides be provided with run through up and down housing 1 to discharge orifice 2, housing 1 periphery is provided with some heat radiation grids 4, this housing 2 and heat radiation grid 4 are by the aluminium die cast.
The utility model is not limited to the foregoing description, and described lens can be more than one a plurality of arbitrarily.
Claims (2)
1, high-power LED street lamp fixture, it is characterized in that: comprise housing, be provided with airtight relatively cavity in the housing, be provided with driver in the cavity, the downside of cavity is provided with at least one lens, is positioned at the lens upside in the cavity and is provided with high-powered LED lamp, and the LED lamp is connected with actuator electrical, the housing of cavity both sides be provided with run through up and down housing to discharge orifice, the housing periphery is provided with some heat radiation grids.
