Light-emitting diode (LED) polarized light underground lamp

Abstract

The invention relates to a light-emitting diode (LED) polarized light underground lamp and belongs to the field of outdoor landscape lighting lamps. The LED polarized light underground lamp is mainly used for plant and building lighting. Existing traditional underground lamps not only are poor in lighting effect and energy saving effect, but also emit light right above in the light-emitting direction, and the light-emitting angles are in bilateral symmetry distribution. Actually, due to the fact that irradiated objects are basically located on one side of a lamp, only part of light can shine on an object, and the remaining is wasted in the air. The LED polarized light underground lamp comprises a sealing base, a power supply, a light source plate having heat dissipation effect, a polarized lens, glass, a sealing rubber ring, a stainless steel mask and screws. Due to the fact that the polarized lens is used for the underground lamp, all emitted light is projected on the irradiated objects through secondary optics, not only is the light fully utilized, but also air pollution of the light is avoided to the largest extent, and the underground lamp has great environmental protection effect. The product is easy to produce and low in cost and is easily popularized and applied by users.

Description

technical field [0001] The invention relates to an LED polarized buried lamp, which is mainly used for outdoor landscape lighting and projecting plants or building objects. Background technique [0002] At present, for outdoor underground lighting, there are mainly the following lighting methods: [0003] 1. Ordinary ground-type metal halide light source floodlight: it is installed and used on the ground, and has a certain adjustment angle, and the light-emitting angle can be adjusted according to the demand. This lighting method has been dominant for a long time, but it also has its own limitations, such as poor luminous brightness, high energy consumption, short service life, and is easy to be stolen. [0004] 2. LED buried lights are buried on the ground, and the light-emitting surface is basically on the same level as the ground; although this kind of LED buried lights solves most of the energy-saving problems from the electrical point of view, at the same time avoids a...

[0004] 2. LED buried lights are buried on the ground, and the light-emitting surface is basically on the same level as the ground; although this kind of LED buried lights solves most of the energy-saving problems from the electrical point of view, at the same time avoids as much as possible The light may be stolen, but the direction of the light emitted is directly above the light, and the light angle is divided symmetrically in the center, so that most of the light cannot be deflected to the illuminated object on one side, wasting most of the light source
