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...
