    [0001] TECHNICAL FIELD The present invention relates to the technical field of semiconductor lighting and in particular that of an LED floodlight whose lighting field reaches 180 degrees of spherical surface. State of the art Nowadays LEDs constitute a new generation of semiconductor lighting, low heat, high light efficiency and long life. Thanks to the constant progress of LED technology, in particular to the development of high power and high efficiency LEDs, in addition to widespread use in the field of ordinary luminaires, LEDs are also widely used in the field of projectors. LED floodlights are mainly used for illuminating the walls of buildings, indoor spaces, walls of historic buildings, gardens and flowered landscapes, billboards, as well as mood lighting in bars and restaurants. nightclubs, or lighting of construction, repair and work sites. With the current single-lamp projectors, since the LED light is unidirectional, when the LED floodlight is on, the maximum vertical and horizontal illumination angle is 120 degrees, with no possibility of increasing this angle, at the same time, the lighting intensity at the front of the projector is much greater than that of the periphery, some areas are dimly lit, or even not at all in certain parts, so when wide-angle lighting is required, some areas remain dark, the lighting angle of these structures is unique, this uneven lighting affects the sales of these products. That is why many builders and people aware of this problem have carried out studies and researches, without however that an ideal product has emerged so far. Content of the Invention The technical problem to be solved by the present invention concerns the state of the above mentioned techniques and consists of providing a 180 degree spherical surface LED floodlight, of simple structure, convenient for installation and maintenance. use, whose field of illumination is important, the radiation is homogeneous and provides good lighting effects.
    [0002] The object of the present invention to solve the above - mentioned technical problem is as follows: a 180 degree spherical surface LED floodlight comprising a window frame, a transparent window, a lamp body, a reflector, integrated LED bulbs, a power supply to the drive, and in which the power supply of the drive is connected and fixed to the lamp body; Characterized in that a bulb mounting base having three inclined surfaces is arranged at the center of said lamp body, the angles measured between the three inclined surface structures are 120 degrees, the angles measured between the perpendicular lines of each surface inclined and the central line of all three inclined surfaces are between 30 and 70 degrees, said integrated LED bulbs are three in number and are respectively fixed correspondingly on each inclined surface of the base of attachment of the bulbs; said reflector is arranged on the front face of the lamp body and is provided with a protuberance which matches the mounting base of the bulbs, said protuberance is provided with projection holes corresponding to the integrated LED lamps; while said pane is of hemispherical surface. Preferably, the angles p measured between the perpendicular lines of each inclined surface of said bulbs mounting base and the center line of all three inclined surfaces are 50 degrees. Preferably, the transparent pane is attached to the lamp body by the pressure exerted by the window frame, a seal is arranged between the transparent pane and the body of the projector, all forming a hermetic waterproof structure and protection against dust . Preferably, said lamp body is provided with an assembly support for adjusting the illumination angle. Preferably, said lamp body is provided with cooling fins, the cooling fins are vertically arranged at the back of said lamp body. Compared with prior art, the present invention has the following advantages and effects: 1. Three integrated LED bulbs respectively attached to the three corresponding inclined surfaces of the bulbs mounting base, as well as a measured p-angle control. between the perpendicular lines of each inclined surface of said base for fixing the bulbs and the center line of all three inclined surfaces, and integrated high power LED bulbs arranged at 120 degrees to each other, constitute a combination of light diffusion allowing at the lighting angle of the luminaire to achieve a 180 degree spherical surface illumination, a large lighting field, excellent lighting effects and homogeneous radiation, which solves the problem of dark areas . 2. The hermetic waterproof and dustproof structure used between the transparent pane and the lamp body offers the possibility of using it in an environment or places where the conditions are bad; 3. The vertically arranged cooling fins on the back of the lamp body provide a structure for vertical airflow to circulate, which speeds up heat exchange and increases cooling efficiency. 4. The projection angle of the projector can be adjusted by means of an overall support for adjusting the illumination angle. Description of the accompanying figures Figure 1 shows the three-dimensional structural scheme of the embodiment of the present invention. Figure 2 shows the projected front plan of the embodiment of the present invention. Figure 3 is a sectional view of the embodiment of the present invention.
    [0003] Fig. 4 is an exploded three-dimensional view of the embodiment of the present invention. Embodiment A more detailed detailed description of the present invention is given below by combining the accompanying figures and the embodiment. Figures 1 to 4 show a preferred embodiment of the 180 degree spherical surface LED floodlight of the present invention.
