Problems solved by technology

Lawn lamps are no exception, but in the application of lawn lamps, most of them choose the way of solar power supply. In this way, the entire lawn lamp can only illuminate the lower part, and the upper part can not reflect the effect.
At the same time, the pattern of the lampshade is relatively fixed in the traditional projection lamps, and the lampshade is not replaced or adjusted according to the demand, so the adaptability is poor

Abstract

The invention provides an LED projection lamp. The LED projection lamp comprises a body support, a cooling panel, an upper light source panel, a lower light source panel and an upper lampshade. The cooling panel is installed on the body support, the upper light source panel and the lower light source panel are installed on the top and at the bottom of the cooling panel respectively, and the upper lampshade is installed on the body support and covers the upper light source panel. Projection sheets are installed on the body support in the circumferential direction, and light of the lower light source panel passes through the projection sheets to be emitted outwards. A plurality of separating plates are arranged on the body support in the circumferential direction and separate the body support into a plurality of projection regions in the circumferential direction. The projection lamp can achieve the purpose that light is emitted from the upper portion and the lower portion simultaneously. The mode of projection is adopted by illumination of the lower portion, so that various light spot patterns are formed. In addition, the projection sheets are designed in a detachable mode, so that the projection sheets with different figures are conveniently replaced. The separating plates are arranged, separate the lower portion into the plurality of independent projection regions in the circumferential direction, and play a role in blocking light, so that the phenomena that due to the fact that light rays in the projection regions are overlapped, light spots are formed on the ground, and double shades exist are avoided.

Description

technical field [0001] The invention belongs to the technical field of lighting, in particular to an LED projection lamp. Background technique [0002] The design of the lawn lamp mainly adds safety and beauty to the urban green landscape with its appearance and soft lighting, and generally has the characteristics of easy installation and strong decoration. It can be used for decoration of green belts in parks, garden villas, square greening, and other places. illumination. With the increasing maturity of LED lighting technology, it has the characteristics of long life, high controllability and energy saving. It has been widely used in landscape lighting. Lawn lamps are no exception, but in the application of lawn lamps, most of them choose solar power supply. In this way, the entire lawn lamp can only illuminate the lower part, and the upper part cannot be embellished. At the same time, the pattern of the lampshade is relatively fixed in the traditional projection lamps,...
