Abstract

The invention relates to a down light with a lens. The down light with the lens comprises a light bead base, multiple light beads and the one-piece lens; the light bead base is a disc-shaped insulating plate, the light beads are fixed to the light bead base, the positive poles and the negative poles of the light beads are connected with a power supply through guide lines, the one-piece lens is composed of a circular base plate and multiple cone-shaped lens bodies, the same faces of the cone bottoms of the cone-shaped lens bodies and the circular base plate are connected together, the tops of the cone-shaped lens bodies are concave inward to form grooves, fixing holes are formed in the edges all around the circular base plate of the one-piece lens, the one-piece lens is fixed with the light bead base through the fixing holes, and the light beads are embedded in the grooves respectively. According to the open-installed down light with the lens, the lens is used in cooperation with the light beads, so that light diffusion of the light beads is more uniform, light around the down light is more uniform, and the situation that only little light exists is avoided, the effect is better, and especially in high altitude, the down light with the lens can be widely applied to the illumination in each field.

Description

technical field [0001] The invention relates to a downlight, in particular to a downlight with a lens. Background technique [0002] The surface-mounted downlight is a ceiling-mounted lighting fixture that emits light from the ceiling surface. Surface-mounted downlights are directional lighting fixtures, and only their opposite sides can receive light. The beam angle belongs to spotlight, the light is concentrated, the contrast between light and dark is strong, and the illuminated objects are more prominent. . [0003] More and more offices and even homes are using LED downlight lighting, because the applicability of LED downlights for indoor lighting is becoming more and more known and more and more popular. LED downlights have the applicability of indoor lighting that is unmatched by other lamps and even other LED lamps. LED downlights do not occupy indoor space. Installing LED downlights indoors will not cause oppressive feeling when used because of the privacy of the ...
