Embodiment Construction

[0018] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0019] Such as figure 1 , figure 2 and image 3 As shown, a LED dining pendant light reflector according to the present invention is designed with a shading angle of 48 degrees, and includes a reflector base. The reflector base is tripod-shaped, and the material used is PC resin. , the pre-drying condition is 120°C×5hr, the nozzle temperature is 230°C-250°C-270°C-260°C, the mold temperature is 70°C, and the annealing treatment condition is 100°C for 2 hours. The inner wall of the base is engraved with a groove, and the groove is formed by a bus bar connected by an eccentric parabola segment and a straight line segment rotating around the axis. It is characterized in that the upper and lower ports of the base body are the light input port and ...

Abstract

The invention discloses an LED (light-emitting diode) pendant lamp reflector, comprising a reflector base body. A groove is carved at the inner wall of the reflector base body. The LED pendant lamp reflector is characterized in that an upper port and a lower port of the base body are respectively a light input port and a light output port; the light output port end is provided with a step and three fixed button positions which are respectively used for installing and fixing a transparent waterproof PC (polycarbonate) plastic board; and three fasteners are arranged at the light input port end and are used for connecting LED lighting aluminium substrates. In the LED pendant lamp reflector, secondary light distribution control is carried out on light emitted by the LED light source, a designwith a 48-degree shielding angle is adopted, and the dazzle problem in the background art is effectively controlled, so that the light pollution is reduced. In addition, considering the LED light output influence, the light rays are guided, so that the effective light output and light utilization rate of a lamp are improved to realize uniform illumination in areas.

Description

technical field [0001] The invention relates to a reflector for a dining pendant light, in particular to a reflector for an LED dining pendant light. Background technique [0002] As a new generation of light sources, LED lamps are quickly accepted by people for their advantages of energy saving, environmental protection, and long life, and gradually replace the status of traditional incandescent and fluorescent lamps. However, when designing the optical system of LED lamps, the designer cannot take into account the actual application scenarios of the lamps, which greatly reduces the lighting quality and destroys the lighting atmosphere. [0003] At present, many dining chandeliers on the market are a simple combination of light sources and lampshades, which do not take into account the actual use requirements of diners, especially the problem of glare. This problem is more prominent in LED dining lighting fixtures. If proper reflectors are not designed for light distributi...
