Embodiment 1

[0017] The structure of the square reflector is as follows figure 1 , 2 As shown in , 3, and 4, it is composed of a square bottom surface 2, four reflective surfaces 4 with identical structures, and an edge 5. A hole 1 for installing a fixed light source is reserved on the bottom surface 2 , and a transition plane 3 with a height of 10 mm is provided around the bottom surface 2 , and the transition plane 3 is basically perpendicular to the bottom surface 2 . The lower ends of the four reflective surfaces 4 are respectively connected to the corresponding transition planes 3 , and the top ends of the reflective surfaces 4 are connected to the edge 5 .

[0018] The reflective surface 4 is formed by connecting four horizontal strip arc surfaces 41, and the longitudinal section of each strip arc surface 41 is a small arc. Therefore, the reflective surface 4 can also be regarded as composed of 4 The surface formed by the horizontal movement of two continuous small circular arcs. ...

Embodiment 2

[0025] The structure of the square reflector is the same as in Embodiment 1, except that the parameters of the arc surface 41 are changed: the radius of the arc BC is 60 mm, the radius of CD is 20 mm, the radius of DE is 120 mm, the radius of EF is 46 mm, and the transition plane 3 The height is 5 mm, and the angle between the intersection line 43 between two adjacent reflective surfaces 4 and the bottom surface 2 is 103°.

Abstract

The invention relates to a square reflecting shade, which consists of a square bottom surface, four same reflecting surfaces connected at the periphery of the bottom surface and edges arranged on the top ends of the reflecting surfaces; and the bottom surface is reserved with a hole position for an LED light source, wherein each reflecting surface of the reflecting shade is formed by connecting a plurality of strip arc surfaces in the horizontal direction; connecting lines for connecting the arc surfaces are parallel to the bottom surface and are parallel with each other; and the arc surfaces forming the reflecting surface gradually expand from bottom to top, so that the reflecting surface tilts outwards for a certain angle to form a square space of which the bottom is small and the upper opening is large. As the unique design scheme is adopted, the reflecting shade remarkably improves the light effect and the utility rate of luminous energy of an LED lamp, so that the LED lamp with the reflecting shade has uniform light emergence and improves the practicability.

Description

technical field [0001] The invention relates to a reflector, in particular to a reflector for an LED lamp. Background technique [0002] With the enhancement of people's awareness of energy conservation and environmental protection, countries are vigorously developing renewable clean energy such as solar energy and wind energy. In the field of lighting, various new light sources are constantly being introduced and widely used. Among them, LED (Light Emitting Diode) is more and more widely used in the lighting field due to its advantages of low energy consumption, high light efficiency, long life and good color rendering. [0003] The reflector refers to a reflector that reflects the light emitted by the light source that cannot be illuminated on the working and living surfaces during the use of the lamp. Using the reflector can greatly improve the light utilization rate of the lamp and greatly improve the efficiency of the lamp. The reflective rate of the reflector depends...
