Lamp with illumination direction and height being adjustable

Abstract

The invention discloses a lamp with the illumination direction and the height being adjustable. A lens device comprises a circular-truncated-cone-shaped lens. A hemispherical gap is formed in the lower portion of the circular-truncated-cone-shaped lens. The central axis of the hemispherical gap coincides with the central axis of the circular-truncated-cone-shaped lens. The portion, inside the hemispherical gap, of the circular-truncated-cone-shaped lens is evenly provided with multiple spherical-segment-shaped light incidence grooves. A cone-shaped gap is formed in the upper end face of the circular-truncated-cone-shaped lens. The bottom face of the cone-shaped gap coincides with the upper bottom face of the circular-truncated-cone-shaped lens. The illumination direction and the height of the lamp are adjustable.

Description

technical field [0001] The invention relates to a lamp with adjustable irradiation direction and height. Background technique [0002] Existing LED lamps are generally fixed, and the irradiation direction and height cannot be adjusted arbitrarily, which brings a lot of inconvenience to users. Due to design defects, the existing lenses for LED lamps generally have unsatisfactory light effects; in addition, existing LED lamps generally use fixed-shaped radiators to dissipate heat. In order to increase the heat dissipation area, generally on the outer wall of the radiator The heat dissipation fins are densely covered, but the heat is concentrated on the outer wall of the radiator during the heat dissipation process, and the heat dissipation effect is not ideal, which seriously affects its service life. Existing radiators used for LED lamps are relatively large in size, require large storage space, and increase transportation costs. [0003] Therefore, the existing lenses and ...

[0002] Existing LED lights are generally fixed, and the irradiation direction and height cannot be adjusted at will, which brings a lot of inconvenience to users

Due to design defects, the existing lenses for LED lamps generally have unsatisfactory light effects; in addition, existing LED lamps generally use fixed-shaped radiators to dissipate heat. In order to increase the heat dissipation area, generally on the outer wall of the radiator The heat dissipation fins are densely covered, but the heat is concentrated on the outer wall of the radiator during the heat dissipation process, and the heat dissipation effect is not ideal, which seriously affects its service life

Existing radiators used for LED lamps are relatively large in size, require a large storage space, and increase transportation costs
