Light distribution system of LED lamp

Abstract

A light distribution system of an LED lamp comprises an irradiated plane, a light source module and a reflection board. The irradiated plane has a vertical direction. The light source module includes a lens. The lens is provided with a light axis and a light emitting face. The light emitting face has a first contour line and a second contour line, wherein the light axis serves as the symmetrical axis of the first contour line and the second contour line. On the section constituted with the light axis in the vertical direction, reflected light from the first contour line irradiates toward one side of the light axis after reflected by the reflection board, and reflected light from the second contour line irradiates toward the two sides of the light axis after reflected by the reflection board. Reflected light of the reflection board irradiates toward the irradiated plane. By means of the lens, the reflection board and the matched effect between the lens and the reflection board, objects on the upper layer and objects on the lower layer of the irradiated plane obtain the same illuminance, accordingly, the light using experience of users can be improved greatly, and the shopping desire of the users is increased.

Description

technical field [0001] The invention relates to the field of lighting equipment, in particular to a light distribution system of an LED lamp. Background technique [0002] In general daily life, various lighting devices can be seen everywhere, for example, fluorescent lamps, street lamps, table lamps, art lamps and the like. Among the above-mentioned lighting devices, traditionally most of them use tungsten filament bulbs as light sources. In recent years, light-emitting diodes (LEDs) have been used as a source of light due to advances in technology. What's more, in addition to lighting equipment, for general traffic signs, billboards, car lights, etc., light-emitting diodes are also used as light-emitting light sources instead. As mentioned above, the advantage of using light-emitting diodes as a light source is that it saves power and has higher brightness, so it has gradually become popular in use.

[0004] This uneven lighting effect is for some occasions, such as exhibition halls, exhibitions, or lighting occasions in some shopping malls. Due to the uneven lighting effect, that is, uneven illumination will reduce the displayed items to visitors or buyers. or visual effects, thereby reducing the visual quality of the displayed items
