TECHNICAL FIELD

The invention relates to the field of electrical appliances, particularly to an intelligent energy-saving LED flood light.

BACKGROUND OF THE INVENTION

Flood lights are designed to illuminate an area to have illuminance above the surrounding environment. The flood lights are mainly used for large areas like operating mines, outline of buildings, stadiums, overpasses, monuments, green landscape lightings, bars, dance halls and so on. As a new generation of lighting source, the LED has advantages such as high brightness, low power consumption, long service life, quick start, small size, environmental friendliness, adjustability etc., and thus is more and more widely used. With the development and progress of high-power LED technology, there have been more and more flood lights using LED as a lighting source.

Nowadays, the available LED flood light generally has a closed space, which has disadvantages such as complex structure, slow heat dissipation, inconvenient assembly and disassembly, short service life, and difficulty in adjusting the angle, and thus affects the lighting effect. At the same time, the flood light mainly uses the silicone waterproof strip to fill the gaps between the glass and the light housing, so as to achieve the required standard waterproof level of the light. The waterproof glue is then filled to achieve the waterproofing. However, in the prior art, the glass is difficult to be compressed and controlled, so the required level of the standard cannot be reached, resulting in a poor waterproofing.

Compared with the prior art, the advantages of the invention are provided as below:

1. The intelligent energy-saving LED flood light of the invention is provided with a row of radiating plates on the lower surface of the housing of the LED flood light, to enhance the cooling capacity of the flood light; next, a row of protruding bars are provided on the bottom wall of the case body, and a radiating rib is provided on the outer wall of the power supply cover, so that the cooling capacity of the flood light is further enhanced to prevent the power supply from overheating and burning out.

2. The intelligent energy-saving LED flood light of the invention is provided with a plurality of drainage holes in the upper surface of the housing, so as to facilitate the rapid discharge of rainwater and avoid the infiltration of rainwater into the LED light board; the gap between the power supply cover plate and the case body is sealed, to improve the waterproof effect.

3. The intelligent energy-saving LED flood light of the invention, wherein the bracket can be formed by hinging two straight arms, and the angle of the hinge connection is adjustable. By adjusting the angle of the hinge connection, it is convenient to adjust the illumination angle of the LED flood light.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The invention will be further described with the drawings and the embodiments as below:

Embodiment 1

As shown in FIGS. 1-3, an intelligent energy-saving LED flood light includes housing 10, LED light board 20 provided on the upper surface of housing 10, power supply components electrically connected to LED light board 20 (which is not shown in the Figure) and U-shaped bracket 40. In the present embodiment, there are two LED light boards 20, and the two LED light boards 20 are mounted on the upper surface of housing 10 side by side and fixed to housing 10 by screws. There is a gap between two LED light boards 20 and the gap is provided with a plurality of drainage holes 11 to discharge the rainwater conveniently and avoid rainwater from infiltrating into LED light boards 20. A row of spaced radiating plates 12 are provided on the lower surface of housing 10, to dissipate the heat generated by LED light boards 20 in time, and to prevent LED light board 20 from burning out. Radiating plates 12 are provided with a plurality of strengthening ribs 121 to improve the strength of radiating plate 12. Power supply case 30 is also provided on the lower surface of housing 10, and power supply case 30 is used for accommodating the power supply components.
