Embodiment Construction

[0027] Such as figure 1 Shown, the present invention comprises upper outer cover 3 and lower outer cover that are connected to each other, and hinge 5 is connected simultaneously on the right end annular surface of upper outer cover 3 and lower outer cover, and the left end annular surface of upper outer cover 3 corresponding with hinge 5 and lower outer cover The hasp 4 is connected simultaneously on the surface, and a cooling through hole is formed on the top of the upper cover 3 . Such as Figure 4 , Figure 5 with Image 6 As shown, the lower outer cover of the present invention is mainly composed of a spherical glass cover 1 and a fixed ring 2 with an L-shaped cross section. 11 stretches obliquely downwards to the inside of the fixed ring 2, and the annular edge of the glass cover 1 is installed between the reversing sheet 11 and the bottom of the fixed ring 2, and the ring surface of the left end of the fixed ring 2 is connected with a cross-section that is L-shaped a...

Abstract

The invention discloses a lamp comprising an upper outer cover (3) and a lower outer cover connected with each other. A light source overlay reflector (6) is mounted inside the upper outer cover (3); the inner surface of the light source overlay reflector (6) is provided with a plurality of spherical protrusions or spherical recesses; the spherical protrusions or spherical recesses are distributed at intervals on the inner surface of the light source overlay reflector (6); the spherical protrusions or spherical recesses are distributed at intervals on the inner surface the light source overlay reflector (6) around the center axis of the light source overlay reflector (6) in a circular form to form a plurality of rings; each ring is composed of multiple spherical protrusions or spherical recesses. Owing to unique spacing design and circular distribution of the spherical protrusions or spherical recesses, the lamp can produce spot light sources which can be overlaid, overall brightness of lamplight is improved, effective reflected light is increased, illumination intensity and reflection efficiency are improved, local heat accumulation is avoided, and the service life of the lamp is prolonged accordingly.

Description

technical field [0001] The invention relates to an energy-saving lighting device, in particular to a lamp used for lighting large-scale places such as industrial workshops, mines, construction sites, squares, and urban roads. Background technique [0002] At present, in the lighting of large-scale places such as industrial plants, mines, construction sites, squares, and urban roads, the connection structure of the lampshade is complicated. The upper and lower parts of the lampshade are often connected by a hoop and screws to replace the bulb. When you need to bring a screwdriver to take out the screws, loosen the hoop, and take out the lower part of the lampshade, you can replace the bulb. The whole operation process is very cumbersome. The reflector inside the lampshade is generally flat and single curved surface to reflect light. Because of the small light reflection angle and the small number of superimposed light sources, the reflection efficiency is relatively low. Whet...
