Embodiment Construction
[0015] Such as Figures 1 to 4 As shown, the floodlight includes a lamp housing composed of a bottom plate 11, an outer ring 12 arranged on the top surface of the bottom plate 11, and an inner ring 13 arranged on the top surface of the bottom plate 11. The inner ring 13 is located in the outer ring 12, and the inner ring 13 The height of the inner ring 13 is lower than that of the outer ring 12. The middle part of the bottom plate 11 has a light outlet 14. The inner ring 13 is provided with a panel 21, a reflector 22 and a light board 23 in sequence from bottom to top. The top of the inner ring 13 is covered with a cover plate 15. , the inner ring 13 is socketed with the cover plate 15, and the two are slidably fitted. An anti-separation structure is provided between the inner ring 13 and the cover plate 15 to prevent the two from detaching. The inner top surface of the cover plate 15 has a 23 The protrusion 16 on the top surface, the side of the lamp board 23 facing the refle...

The invention provides a project lamp which comprises a lamp shell. The lamp shell is composed of a bottom plate, an outer ring arranged on the top face of the bottom plate and an inner ring arranged on the top face of the bottom plate, the inner ring is arranged in the outer ring, the height of the inner ring is smaller than that of the outer ring, a light emitting hole is formed in the middle of the bottom plate, a light reflecting cup is arranged in the inner ring, the light reflecting face of the light reflecting cup is defined by an upper light reflecting face, a lower light reflecting face, a left light reflecting face and a right light reflecting face, the included angle between the upper light reflecting face and the plane which is between the upper light reflecting face and the lower light reflecting face and is parallel to the bottom face of the bottom plate is 0-45 degrees, the included angle between the lower light reflecting face and the plane which is between the upper light reflecting face and the lower light reflecting face and is parallel to the bottom face of the bottom plate is 60-90 degrees, the left light reflecting face and the right light reflecting face are of a symmetric structure, the included angle formed by the left light reflecting face and the right light reflecting face is 90 degrees, and the distance between a through hole in the top of the light reflecting cup and an opening in the bottom of the light reflecting cup is large than 10 mm. A spot lamp can be adjusted, the large projection area can be obtained by rotating the project lamp by a small range, the water preventing effect is achieved, the outdoor using effect is excellent, the service life is long, the heat radiation effect is good, and the structure is firm.
Description
technical field [0001] The invention relates to a floodlight. Background technique [0002] Floodlights are mainly used in large-area mines, building outlines, stadiums, overpasses, monuments, parks and flower beds, etc. Floodlights can be seen in almost all large-area lighting fixtures used outdoors. The output beam angle of the floodlight is wide or narrow, and the range of variation is between 0° and 180°. Existing floodlights have problems such as narrow light projection range, easy structure damage, troublesome correction and adjustment of concentration, and the like. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a floodlight, which can adjust the position of the light-transmitting mirror relative to the reflector cup, and then adjust the degree of concentration. It has a large projection area within a wide range, has waterproof effect, excellent outdoor use effect, long service life, good heat dissipati...
