LED three-dimensional lamp

Abstract

The invention relates to an LED three-dimensional lamp, which comprises a shell, a first reflecting plate, a light guide plate, a first light diffusion plate and a second light diffusion plate, wherein a light source module is arranged in the shell and used for generating a light source of the lamp; the first reflecting plate is made of a light reflection material and is arranged at the bottom; the light guide plate is arranged on the upper part of the first reflecting plate, and the light emitting direction of the light source module is vertical to the main light emergent surface of the light guide plate; and the first light diffusion plate and the second light diffusion plate are arranged on two opposite sides of the light guide plate, and are used for forming a side light emergent surface vertical to the main light emergent surface of the light guide plate so as to form the three-dimensional light emergent effect.

Description

technical field [0001] The invention relates to a lamp, in particular to a lamp which adopts LED as a light source and produces a three-dimensional lighting effect. Background technique [0002] The light sources of traditional lighting fixtures include incandescent lamps, halogen lamps, fluorescent lamps, etc. The low light source efficiency and large amount of heat energy waste of incandescent lamps and halogen lamps have gradually withdrawn from the lighting field and are only used in some special occasions. Although fluorescent lamps have higher light source efficiency, they require frequency conversion efficiency for high-frequency and high-voltage startup, which reduces the overall efficiency by about 20%. Moreover, the brightness of fluorescent lamps cannot be adjusted and the color tone is single. LED (Light Emitting Diode) just produces for this reason; [0003] The LED is a semiconductor solid light-emitting device that can emit visible light, ultraviolet light, a...

Problems solved by technology

[0004] There are also LED lamps on the market at present, please refer to Figure 1A as well as Figure 1B As shown, they are respectively a schematic cross-sectional view and a bottom view of Embodiment 1 of an existing LED lamp; it has a tapered shell 1, and a circuit board 21 is arranged inside the shell 1, and the circuit board 21 is There are several LED22; see also figure 2 As shown, it is a schematic cross-sectional view of the second embodiment of the existing LED lamp; its main feature is that a light-transmitting cover is packaged at the shell 1 of the LED lamp, and the light-transmitting cover 3 is made of glass material and plastic materials; but these lamps are not set with light-diffusing materials (that is, using light mixing technology), and the light emitted by each LED 22 or chip can be directly seen. Because the directivity of LED22 light is very strong, when the number of LED22 is small , the brightness of the lamp is not enough; when the brightness meets the lighting requirements, it is particularly dazzling; when the known LED lamp has only one set of LED22 or chips, it can only emit light from the front, which is to produce the effect of one-dimensional light
