Background technology
LED street lamp and semi-conductor lighting lamp, using light emitting diode as light source, because it is a kind of solid-state cold light source, have the features such as environment friendly and pollution-free, little power consumption, light efficiency are high, the life-span is long.But because it is generally applied in road, bridge, the place that the spaces such as stadiums are larger, then need to adopt more high-power LED lamp, illumination needs could be met, along with the increase of power, the caloric value of LED street lamp and driver thereof is also large, the light efficiency of LED can decline along with the rising of temperature, service life also can Yin Wendu rising and shorten, therefore, existing LED street lamp usually all can by arranging radiator structure to ensure the light efficiency of LED, a kind of LED street lamp as disclosed in Chinese patent [application publication number: CN104421760A], comprise housing and light source, described housing upper surface is provided with some guiding gutters installed for louvre, radiator structure is provided with in described each guiding gutter.But owing to using under LED street lamp all in the open environment, under rainy day and wet environment, the easy ponding of radiator structure of upper surface guiding gutter and affect radiating effect.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, and propose a kind of LED street lamp, it can be dredged ponding, avoids deposition.
The purpose of this utility model realizes by following technical proposal: a kind of LED street lamp, comprise housing and several LED lamp panel, in described housing, electrically-controlled component is installed, it is characterized in that, described LED lamp panel is connected on housing downside, and LED lamp panel is connected with electrically-controlled component, described housing upper surface has forward and heat radiation cavity uncovered upward, in described heat radiation cavity, there is several fin, and heat radiation cavity is divided into several guiding gutters by several fin, the bottom of described guiding gutter is provided with the pod apertures running through housing.
In the technical program, housing has front-end and back-end, rear end has the mounting structure for this LED street lamp being arranged on wall or lamppost, and electrically-controlled component is built in the inner chamber of housing rear end, LED lamp panel in use can produce a large amount of heats, these heats can be passed on housing and fin fast, heat radiation cavity is divided into upward some and uncovered guiding gutter forward by the fin be arranged in housing forward end heat radiation cavity, above-mentioned guiding gutter is easy ponding under rainy day and wet environment, the technical program is by being arranged on the lowest part of guiding gutter by pod apertures, ponding can be dredged, thus ensure the radiating effect of housing, avoid the ponding gathered for a long time to housing, the erosion that automatically controlled circuit and LED lamp panel etc. cause.
In above-mentioned LED street lamp, described heat radiation cavity has a rear surface and a bottom surface, and the angle between described rear surface and bottom surface is obtuse angle, and described pod apertures is opened on the connecting portion between rear surface and bottom surface.Angle between rear surface and bottom surface is obtuse angle, and rear surface is inclined relative to horizontal, and the water be easy on housing carries out gathering and being dredged by water conservancy diversion stream.
In above-mentioned LED street lamp, the angle number of degrees between described rear surface and bottom surface are 120 ° ~ 150 °.LED street lamp has larger irradiated area to ensure in use, usually all LED street lamp can be tilted in the longitudinal direction, namely LED street lamp has certain elevation angle, above-mentioned angle design can make the rear surface of heat radiation cavity and bottom surface all with respect to the horizontal plane be upturned, thus the ponding that cavity gathers of making to dispel the heat can be smoothly through pod apertures dredges, the rear end of housing can also be made to have enough spaces for holding electrically-controlled component simultaneously.
In above-mentioned LED street lamp, center line and the bottom surface of described pod apertures are perpendicular.Above-mentioned setting can make the degree of depth of pod apertures minimum, optimizes shell structure, ensures dredging smoothly of ponding.
In above-mentioned LED street lamp, each described fin is parallel to each other and all arranges along the length direction of housing.LED street lamp is strip structure, and width and the lamp stand of housing are perpendicular, and the length direction of housing is the front and back end line of housing, due to LED street lamp in use, its width parallels with horizontal plane and can not tilt, and is easy to dredge ponding.
In above-mentioned LED street lamp, described fin upper edge is curved, and the rear end of fin upper edge flushes with the upper edge of rear surface, and the front end of fin upper edge and the front of bottom surface are along flushing.Fin flushes with the edge of rear surface and bottom surface respectively, can dredge better ponding, avoids ponding to be collected on the connecting portion of fin and rear surface or fin and bottom surface.
Compared with prior art, housing upper surface is marked off several guiding gutters by fin by the utility model, can gather, and dredged by pod apertures ponding, avoid ponding to cause erosion to housing, automatically controlled circuit and LED lamp panel etc., extend the service life of LED street lamp.
