Problems solved by technology

Many existing LED lamps use multiple lamp beads to emit light together. This method can effectively increase the light intensity, but it also makes the source of the light source become multiple. Use the traditional method of installing a conical reflective surface behind the bulb Difficulty concentrating the light due to the large number of bulbs and the off-center location of the light source
The existing solution is to place each lamp bead in a conical reflective groove, but this can only gather the light emitted by each lamp bead separately to form multiple cone-shaped rays of light, but it cannot integrate all the lamp beads. The rays of light are gathered together, and the effect is limited

specific Embodiment

[0052] Such as Figures 1 to 3 As shown, a lamp cover 10, the middle part of the lamp cover 10 is a light-transmitting layer 1 protruding outward; the inner side of the light-transmitting layer 1 is provided with five convex surfaces 2 for gathering light; each of the A ring-shaped protrusion 3 for changing the direction of light propagation is provided around each convex surface 2; . The projection of the surface of the annular protrusion 3 close to the axis on the axial section of the annular protrusion is a curve.

[0053] The two adjacent ring-shaped protrusions 3 are connected to each other, and all the ring-shaped protrusions 3 are connected as a whole; the inner side of the light-transmitting layer 1 is provided with four reinforcing ribs 4; the reinforcing ribs 4 are regularly distributed in the ring Raised around the whole. The two ends of each reinforcing rib 4 are respectively connected with the annular protrusion 3 and the edge of the lamp cover. The inner side...

Abstract

The invention relates to the lighting field, in particular to a lamp cover and a light emitting diode lamp adopting the lamp cover, wherein the middle portion of the lamp cover is provided with an outwardly protruded euphotic layer, the inner side of the euphotic layer is provided with convex surfaces for gathering light rays, the surrounding of each convex surface is provided with a ring-shaped bulge for changing propagation directions of the light rays, and the protruded directions of the convex surfaces and the ring-shaped bulges are the same and are all opposite to the protruded direction of the euphotic layer. The light emitting diode lamp adopting the lamp cover comprises a lamp bead, a lamp shell and a lamp cover, wherein the lamp bead is arranged in the lamp shell, the lamp cover is covered on the outer side of the lamp bead, and the edge of the lamp cover is connected with the lamp shell. The lamp cover is provided with the convex surfaces for gathering the light rays and the ring-shaped bulges, can gather the light rays ejected by each lamp bead by reflecting and refracting, gathers the light rays ejected by all the lamp bead together, and increases irradiation intensity of the light rays. The light emitting diode lamp adopting the lamp cover is stronger in lighting under the conditions of the same power consumption, and is farther in irradiation range.

Description

technical field [0001] The invention relates to the lighting field, in particular to a lamp cover and a light-emitting diode lamp using the lamp cover. Background technique [0002] With the gradual improvement of people's awareness of energy saving and environmental protection, traditional incandescent lamps have been replaced by more energy-saving light-emitting diode lamps. Many existing LED lamps use multiple lamp beads to emit light together. This method can effectively increase the light intensity, but it also makes the source of the light source become multiple. Use the traditional method of installing a conical reflective surface behind the bulb It will be difficult to concentrate the light due to the large number of bulbs and the location of the light source not in the center. The existing solution is to place each lamp bead in a conical reflective groove, but this can only gather the light emitted by each lamp bead separately to form multiple cone-shaped rays of l...
