BACKGROUND

1. Technical Field

The present disclosure generally relates to the field of lighting technologies, and especially relates to a lighting lamp.

2. Description of Related Art

Conventional LED lamps generally include lighting bars, bulb lamps, spotlights and high-power mining lamps. The lighting bar, with a small power, is only suitable for decoration and other fields, which can't meet a condition with a long-distance and a large-range lighting. The bulb lamp has a relatively large lighting range and a poor heat dissipation effect, so that it is not suitable for a high-power lighting condition and can only be used a household lighting, which can't meet requirements of outdoors, warehouse or portable lighting. The spotlight has a small power and is difficult to adjust an irradiation range and an irradiation angle thereof.

The mining lamp with a high power is mainly installed in open areas, such as a warehouse and a public place by means of a fixed installation way, which are characterized by a high power and a high brightness, rather than meeting requirements of portable lighting; in addition, for different lighting environments, a lighting direction and an irradiation angle of the mining lamp also can't be adjusted, which is inconvenient to be operated. Even if there are some adjustable mining lamps, users need to adjust a lamp supporter of the mining lamp that is installed at a specific position such as a wall, which is very inconvenient.

At present, in the field of lighting, there is no lighting lamp with multi-functions and multi-scene applications that can easily adjust the irradiation angle thereof, be portable and adopt a variety of power supply modes.
