technical field

The utility model relates to a device for indoor and outdoor lighting, in particular to an LED lighting device which can increase the projection angle of a light source and increase the brightness effect at the same time, and belongs to the technical field of lighting fixture manufacturing.

Background technique

Civilian lighting fixtures generally use tungsten filament bulbs. This traditional tungsten filament bulb consumes a lot of electricity, but now LED light-emitting components are gradually popularized due to energy saving, long service life, and stable light intensity. When distinguishing between the two lighting modes, traditional tungsten filament bulbs have a fan-shaped light source, while LED bulbs have a bright projection light source, but they are very different from traditional tungsten filaments. The light source effect is mainly projected in a straight line. limitations, thereby affecting its popularity.

The light source characteristics of LED light-emitting diodes are: the smaller the angle of light emission, the brighter the light source will be, on the contrary, the larger the angle will be, the darker the brightness will be, which cannot achieve a light source similar to the shape of a light bulb fan. To improve, it is possible to expand the irradiation range and brightness.

In addition, the heat generation of high-power LED light-emitting tubes also affects their service life.
