Problems solved by technology

Among them, if you increase the high-power LED () luminous body, the heat will be larger; if you increase the number (or density) of LEDs, because they are installed on the same plane, the heat generated by the light cannot be dissipated in time and quickly, making the metal base hot

Embodiment

[0018] Example: LED lamps arranged in multiple layers, such as figure 1 , figure 2 and image 3 As shown, it includes a lampshade 8, an anti-scalding cover 9 matched with the lampshade 8, a base 1 (the material is aluminum or copper) built into the lampshade 8 and the anti-scalding cover 9, and set in the inner cavity of the base The circuit board, the driving power supply 14, and the LED illuminant 2 installed on the base and electrically connected to the circuit board. The mounting part of the base 1 is provided with a positioning convex ring 6, which is parallel to the first light-emitting plane 3 and is located below the third light-emitting surface 5. There are a plurality of recessed grooves 15 spaced apart from the edge of the positioning convex ring 6, and the positioning convex ring 6 is spaced apart. The position between the two adjacent grooves on the ring 6 is the positioning part 16, the positioning part 16 and the anti-scald cover 9 are connected by a connecti...

Abstract

The invention relates to a multi-layered LED (light emitting diode) lamp, wherein the LED lamp comprises a base, a circuit board, a driving power supply, LED illuminating bodies and a lamp cover, wherein the circuit board and the driving power supply are arranged in the cavity of the base; the LED illuminating bodies are installed at the surface of the base and are electrically connected with the circuit board; the lamp cover is arranged on the base; the surface of the base is at least provided with three light emitting surfaces of the LED illuminating bodies; and the light emitting surfaces are arranged in a layered manner, and each light emitting surface is provided with a plurality of LED illuminating bodies which are distributed uniformly. The multi-layered LED lamp has the following obvious and substantive characteristics: the LED illuminating bodies on the base are distributed in multilayers and are matched with the lamp cover, thus the light can be illuminated on the lamp cover uniformly, the ray of light emitted from the lamp cover is gentle, three-dimensional and rich, has no color cast, and is not dazzling; and because small power LED chips are adopted, heat capacity is decreased, the metal base is minimized, the lamp cover and a burning-proof cover are made of plastics, the weight and the manufacturing cost are lowered, the installation stability is improved, falling-off and scalding are prevented, and the energy-saving effect is good.

Description

Technical field [0001] The invention relates to an illuminating lamp, in particular to a LED lamp arranged in multiple layers. Background technique [0002] The LEDs on the base of the existing LED energy-saving lighting lamps are usually only arranged at one end of the base and on the same plane, so that the light is concentrated, and there is no lampshade to soften the decoration, which is glaring and has color shift. Even if the lampshade is added, since the LED illuminant is arranged on a plane, the light intensity on the lampshade is different, and there are bright and dark areas, and the lighting modification effect is not ideal. [0003] At the same time, the LED illuminants are arranged on a plane, and in order to increase the brightness, usually high-power LED illuminants are used or the number (or density) of LEDs is increased. Among them, if the high-power LED () luminous body is added, the heat generation will be large; if the number (or density) of the LEDs is ...
