Abstract

An LED flood lamp includes a light transmitting plate, an LED module, a support and a rear casing, wherein the LED module is mounted in the rear casing; the light transmitting plate and the rear casing are closed to form a space for accommodating the LED module; the support is mounted on the rear casing; the rear casing includes a back plate, left and right side plates, an upper side plate and a lower side plate; the back plate is parallel to the light transmitting plate; and parallel cooling fins are arranged on the back plate and extend from the upper end to the lower end of the back plate. The rear casing of the LED flood lamp adopts the integral designed heat dissipation structure, the heat dissipation is smooth, and neither heat insulation nor heat resistance exists, so that higher illumination intensity can be born, the heat dissipation effect is enhanced, the temperature of the LED flood lamp is lowered, and the service life of the LED flood lamp is prolonged.

Description

A kind of LED floodlight
Technical field
The utility model relates to lighting technical field, particularly relates to a kind of LED floodlight.
Background technology
The LED floodlight generally is used for throwing light on a large scale, it is uniform irradiation to all the winds, range of exposures can be adjusted arbitrarily, in scene, can show as the icon of a regular octahedron, in the middle of design sketch is made also is most widely used a kind of light source, standard LED floodlight usually is used for illuminating whole scene, and adopts many LED floodlights simultaneously, to produce effect preferably.Its structure is that led module for shooting is put in the large-scale reflecting umbrella, and the diffused light source that is made for high brightness uses, and is not only indispensable in the canopy intraoral illumination, and for the pickup of general sparetime, also is one of best light source of illuminating effect.
The LED floodlight is owing to the brightness height, so the heat generation is also very huge, influences the LED floodlight life-span.
The utility model content
The purpose of this utility model is to avoid weak point of the prior art and a kind of LED floodlight with good radiator structure is provided, and it can prolong the service life of LED floodlight.
The purpose of this utility model realizes by following technical measures.
A kind of LED floodlight, comprise light-passing board, led module, support and back cover, described led module is installed in the back cover, described light-passing board and the sealing of described back cover form the space that holds described led module, described support is installed on described back cover, and described back cover comprises backboard, left side plate, epipleural and lower side panel, and described backboard is parallel to described light-passing board, described backboard is provided with the radiating fin that is parallel to each other, and described radiating fin extends to the lower end by the upper end of described backboard.
Described radiating fin is provided with fillet near the position of the top and bottom of described backboard.
Described epipleural is provided with fin, described fin extends to described backboard by the direction near described light-passing board 1, the height of the position of the close described light-passing board 1 of described fin is concordant with described light-passing board, the height of described fin by described position near light-passing board 1 gradually transition be zero.
The profile of described radiating fin is that inequilateral is trapezoidal, and its angle that is positioned at the side of described backboard lower end and base is less than 60 °.
Described support is installed on the lower end of the left side plate of described back cover.
Back cover of the present utility model has adopted the radiator structure of one design, and therefore the unobstructed no heat insulation thermal resistance of dispelling the heat can bear higher illumination intensity, has strengthened heat radiation, has reduced LED floodlight temperature, has prolonged the service life of LED floodlight.
