Abstract
The invention aims to solve the problem of a narrow light distribution angle of an existing LED bulb, and provides an LED bulb with an all-dimensional illumination function. The LED bulb is characterized in that a radiator of the LED bulb is of a multilayer structure, and comprises a first-layer radiator and a second-layer radiator as shown in a graph, the second-layer radiator is in the shape of an inverted cone frustum, and a side surface of the second-layer radiator is a reflective surface. When projection is carried out towards the first-layer radiator from the upper side of the second-layer radiator, at least a part of a luminous surface of a first LED light source assembly on the first-layer radiator is positioned within a projection region of the second-layer radiator. Accordingly, light emitted by the first LED light source assembly mounted on the first-layer radiator can be emergent to a side surface and the back surface of the luminous surface after being reflected by the side surface of the second-layer radiator, and light emitted by a second LED light source assembly on the second-layer radiator is emergent at the exact front of the luminous surface. Accordingly, a light distribution angle of the LED bulb is close to a light distribution angle of an incandescent lamp, and the all-dimensional illumination function of the LED bulb is realized.
Description
Technical field
The invention belongs to the LED field of semiconductor illumination.The LED bulb that relates to a kind of all-directional illumination.
Background technology
Incandescent lamp almost can send light from front, side and the back all directions of lamp except cap part is not luminous.Therefore incandescent lamp is used to multiple occasion, such as the lighting that utilizes the incandescent lamp lateral emitting etc. be employed very extensive.But incandescent lamp also has short, the shortcoming such as light efficiency is low, power consumption is high of life-span.
The LED bulb have the life-span long, light efficiency is high, radiationless, shock resistance and the advantage such as low that consumes energy, and is progressively replacing incandescent lamp.But because existing LED bulb is very strong from the directive property that illuminating part sends light, so light almost shines less than departing from place in addition, 60 ° of angles, illuminating part dead ahead, the luminous intensity distribution angle of therefore existing LED bulb is all below 120 °.Compared with conventional incandescent lamp source that can the omnirange luminous intensity distribution, the luminous intensity distribution angle of existing LED bulb seems very narrow, and especially its light can not reach the back of lamp, can form shadow.And because the luminous intensity distribution angle of incandescent lamp and LED bulb is different, be installed in separately in the lighting with the reflector that light can be concentrated on the place ahead, resulting distribution curve flux also is distinct.Therefore, existing LED bulb can't replace incandescent light source fully.
Summary of the invention
The present invention is in order to solve the narrow problem in luminous intensity distribution angle of existing LED bulb, a kind of LED bulb of all-directional illumination to be provided.
Overall structure of the present invention forms as shown in Figure 1 and Figure 2, and comprising: diffuser 1, led light source assembly 2 21, led light source assembly 1, second layer radiator 31, ground floor radiator 32, drive circuit board 4, base 5, lamp holder 6 form.
The radiator that the led light source assembly is installed among the present invention has multi-level structure.Shown in Fig. 3 the first embodiment of the present invention, the radiator part that the led light source assembly is installed is made of ground floor radiator and second layer radiator.The ground floor radiator central portion connecting the second layer radiator of rounding frustum shape, and the side of second layer radiator is comprised of reflective surface.A plurality of led light source assemblies have been installed on the multilayered structure radiator.When doing projection from the upper direction ground floor radiator of second layer radiator, the light-emitting area that is installed in the led light source assembly one on the ground floor radiator has at least the part should be in the view field of second layer radiator.Therefore be installed in the light (as shown in Figure 3 L1) that the led light source assembly one on the ground floor radiator sends, after the reflection through second layer radiator side (reflective surface), (as shown in Figure 3 L2) penetrated in the side of light led light source assembly one on the ground floor radiator and the angle at the back side.Be installed in like this light that the led light source assembly one on the ground floor radiator sends and both can penetrate (as shown in Figure 3 L3) with interior angle in 60 ° of angles from the light-emitting area dead ahead, again can be from the light-emitting area dead ahead angles beyond 60 ° of angles penetrate (as shown in Figure 3 L2); And be installed in light that the led light source assembly two on the second layer radiator sends all in 60 ° of angles, light-emitting area dead ahead.Therefore luminous intensity distribution of the present invention angle has been realized omnibearing luminous closer to the luminous intensity distribution angle of incandescent lamp.
According to the luminous intensity distribution angle needs of reality, the multilayered structure of radiator also can adopt the tri-layer structure shown in Fig. 4 second embodiment of the invention.The level of radiator is more, and just more close to incandescent lamp, the light that sends is also more even, does not have hot spot at the luminous intensity distribution angle of LED bulb.
