Abstract

The invention discloses a light distribution system for a strip-shaped LED lamp. The light distribution system for the strip-shaped LED lamp comprises a light source module, a light-reflecting device and an irradiated surface. The light source module comprises at least one LED chip. The light-reflecting device comprises a front light-reflecting surface, the front light-reflecting surface comprises a ground irradiation section used for irradiating the ground, a long-distance section and a short-distance section, and the optical axis is intersected with the contour line of the long-distance section. The ground irradiation section comprises a first curvature, the long-distance irradiation section comprises a second curvature, the short-distance irradiation section comprises a third curvature, the first curvature is greater than the second curvature, and the second curvature is greater than the third curvature. According to the light distribution system for the strip-shaped LED lamp, the main irradiated surface can obtain the basically same illuminance in the vertical direction thereof under the mutual matching of the long-distance irradiation section and the short-distance irradiation section of the light-reflecting device, so that the light use experience of a user can be greatly improved, and the shopping desire of the user 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 strip 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. [0003] Such as figure 1 Shown is a schematic diagram of an opt...
