Problems solved by technology

But its disadvantage is that this adjustment method can only provide two fixed interchangeable angles, and it can only be realized after the lamp head cover is removed and replaced by 180 degrees and then installed. Not only is the operation complicated, but also the optional projection angle is only Two, far from meeting the actual needs

Embodiment Construction

[0016] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0017] As shown in the figure, the lamp body 3 is rotatably connected to the outer frame 2 , the lamp body 2 has a reflector 4 and a lamp tube 5 , and the lamp tube 5 is installed in the reflector 4 . Because the lamp body 3 is connected to the outer frame 2 in a rotatable manner, and at the same time, the outer frame 2 is also connected to the bracket 1 in a rotatable manner, so the lamp body 3 can be conveniently adjusted according to the needs of users 3 projection angles, so that users can easily adjust the angle of lighting projection. The connection between the lamp body 3 and the outer frame 2 can be any form of rotatable connection, so as to realize convenient adjustment of the projection angle of the lamp body 3 and keep the lamp body 3 stably at a certain angle. The connection betwee...

Abstract

The invention relates to a flood lamp for short distance projection in a large-area projection place, in particularly to a flood lamp capable of adjusting projection angles. The flood lamp comprises at least two lamp units, each of which comprises a light reflection device and one or two lamps, the lamp units are arranged on an outer frame, the lamps are connected with the outer frame in a rotatable manner, and the outer frame is arranged on a bracket and connected with the bracket in a rotatable manner. In addition, the number of the lamp units in normally 2-4, the light reflection device has a shape for asymmetric projection, the lamp units are vertically or transversely arranged on the outer frame. The inventive flood lamp can conveniently adjust the projection angles of the lamp units, and one such flood lamp can satisfy the requirements on lighting toward multiple directions or in a place with different directions at the same time. In addition, by using the light reflection device with the shape for asymmetric projection, the lamp can realize uniform lighting in a position with a closer distance to an object to be lighted.

Description

technical field [0001] The invention relates to the field of illumination lamps, in particular to a floodlight lamp for short-distance projection in large-area light projection places. Background technique [0002] In the actual use of floodlights, users have different requirements for the projection angle of floodlights, and sometimes they will constantly adjust the projection angle of the lamps according to the needs of the place to be illuminated or the work. However, most of the floodlights currently used have a fixed projection angle, because the projection angle of this type of floodlight mainly depends on the high-intensity gas discharge lamp installed in the floodlight lamp body and the lamp body. The angle formed by the reflector forms a fixed projection angle. [0003] At present, there are also some models that can change the projection angle in the market. For example, the patent number is 00249130.3, and the patentee is a utility model patent of a floodlight th...
