LED lamp capable of realizing directional projection and top suction type range hood applying LED lamp

Abstract

An LED lamp capable of realizing directional projection comprises a lamp panel (4), LED light-emitting bodies (6) and lenses (5), and the LED light-emitting bodies (6) are arranged on the lamp panel (4). The lamp is characterized in that an accommodating groove (54) for arranging a light source is formed in the back end of each lens (5); the side surface of each accommodating groove (54) is an inner tapered concave surface (55); the bottom surface of each accommodating groove (54) is an arc-shaped outwards-convex curved surface (56); a light incoming surface is formed by each inner tapered concave surface (55) and the corresponding arc-shaped outwards-convex curved surface (56); the central axis of each LED light-emitting body (6) is parallel with the central axis of the corresponding lens(5); and besides, the central axis of each arc-shaped outwards-convex curved surface (56) is deviated from the central axis of the corresponding LED light-emitting body (6), and a sharp angle is formed by the central axis of each arc-shaped outwards-convex curved surface (56) and the central axis of the corresponding LED light-emitting body (6). The LED light-emitting bodies (6) are deviated fromthe central axes of the lenses, so that light emitted from the light outgoing surfaces of the lenses is emitted obliquely, and the light cannot be emitted onto a wall or a person through design adjustment.

Description

technical field [0001] The invention relates to a lamp, which belongs to the technical field of lighting, and also relates to a range hood using the lamp. Background technique [0002] Such as figure 1 As shown, the range hood currently on the market includes a casing 1a, a fan and a smoke collection hood 3a. It has an inclined surface 31, and the LED lamp 4a is provided on the inclined surface 31a. The light boards of the existing LED lamps 4a are generally fixed in parallel in the lamp housing. In order to make the overall appearance of the lamps uniform, they generally choose to keep the inclined surface flat. However, the light on the operating table of the stove is insufficient and relatively dark, which cannot achieve the photopic lighting effect during use. [0003] For this reason, some improvements have been made in the prior art. See the Chinese invention patent application "A European Range Hood with Eccentric Illumination" (Application Publication No.: CN10484...

AI Technical Summary

Problems solved by technology

The light boards of the existing LED lamps 4a are generally fixed in parallel in the lamp housing. In order to make the overall appearance of the lamps uniform, they generally choose to keep the inclined surface flat. However, the light on the operating table of the cooker is not sufficient and is relatively dark, which cannot achieve the photopic lighting effect when in use.
