A row of U-shaped energy-saving fluorescent lamps are fixed on the inner lamp holder. Although the reflector and the brightness of a row of fluorescent lamps are larger, it can only illuminate the front range of the lamp and cannot illuminate in all directions. It is also not suitable for engineering lamps.

Contents of the invention

The technical problem to be solved by the present invention is to provide a mobile engineering lamp, which not only has a long lighting distance, but also has a large brightness, can realize hemispherical wide-angle illumination, and can change the use position or height of the engineering lamp at any time according to needs, and is easy to use and carry ,Safety.

The technical solution adopted by the present invention to solve the above problems is: mobile engineering lamp, including a cavity composed of a lampshade with a handle and a base, and a 2D fluorescent tube, a ballast, a reflector, and a terminal are installed in the cavity , protective ring, the base is fixed with a fixed seat, and the fixed seat is formed by connecting two or more supporting plates. There is a 2D fluorescent tube fixed on the lamp holder, a bottom reflector is also fixed on the base, a suspender is fixed at one end of the handle, and the suspender is connected with the bracket sleeve connected to the base, and the lampshade is connected to the base fixed into one.

Compared with the prior art, the present invention has the advantages that all electronic components and connecting wires of the lamp are installed in the shielding field of the cavity of the fixing seat formed by the reflector and the supporting plate, and can be viewed from the outside of the transparent lampshade. The inside is neat and beautiful, without messy wires, no shadows after the light is irradiated, and there will be no electromagnetic interference, and three high-power 2D fluorescent tubes evenly distributed on the periphery of the fixing seat are used as light sources. The slope of the fixing seat is equipped with a reflector structure, which makes full use of the reflected light of the 2D fluorescent tube, so it is brighter and energy-saving. It also uses a lampshade composed of three arc surfaces to achieve hemispherical wide-angle lighting, 360° °>Illumination range>180°. The connection between the transparent lampshade and the base is padded with rubber pads, the base feet are covered with rubber feet, and the handle is plugged with a sealing head, which is waterproof and suitable for outdoor work. As long as the handle is turned, the suspender can be unscrewed from the screw hole on the bracket sleeve, and the lampshade is detached from the base to expose the 2D fluorescent lamp tube, which is convenient and fast for replacement or maintenance and disassembly of the lamp tube. There is a handle on the lamp to hang, hang, hook on the wall or hang in the air, hang upside down or put it on hold, and use it by hand. The use position can be changed at any time. It is convenient, flexible and safe to use.

Three identical equilateral trapezoidal supporting plates are fixed by spot welding into a fixed seat 11 with an equilateral hexagonal cross-section. The top surface of the fixed seat 11 is also fixed with screws to cover the cover plate 6 with a through hole in the middle. The reflective plate 7 matching the shape of the supporting plate is fixed with screws on the three supporting plate slopes of the seat 11, and three arc-shaped bottom reflecting plates 12 are fixed with screws on the base 10 except for the position of the middle fixing seat. The middle position of the base is Equilateral triangle with the same shape of the fixed seat, a boss with a through hole is arranged in the triangle, and the bracket cover 16 inserts with screw holes are fixed in the boss, and on the lamp holder 9 on the three slopes of the fixed seat 11, three lamp holders are fixed respectively. A high-power 2D fluorescent tube 8 is used as the fluorescent light source of the engineering lamp, as shown in Figure 2.

Fix the ballast 17 on the inclined surface of the inner wall of the fixed seat 11, and connect the components with wires, and shield them in the inner cavity of the fixed seat 11 to prevent radiation and electromagnetic interference.
