The first embodiment is as follows:

as shown in fig. 1 to 4, an LED or the like according to a first embodiment of the present invention includes a housing 10, an LED light source member 20, and an optical member 30, where the LED light source member 20 includes a first LED light emitting portion 21 and a second LED light emitting portion 22, the optical member 30 includes a light guide portion 31 and a refractive lens 32, and the refractive lens 32 surrounds the light guide portion 31. In the process of assembling the LED lamp, the housing 10 is provided with an accommodating space 12, the LED light source member 20 is installed in the accommodating space 12, the second LED light emitting part 22 surrounds the first LED light emitting part 21, the light emitting power of the second LED light emitting part 22 is higher than that of the first LED light emitting part 21, the optical member 30 is installed in the accommodating space 12, the first LED light emitting part 21 is coupled with the light guide part 31, the second LED light emitting part 22 is coupled with the refractive lens 32, so that the light emitted by the first LED light emitting part 21 is guided out through the light guide part 31, and the light emitted by the second LED light emitting part 22 is guided out through the refractive lens 32.

Specifically, light guide unit 31 covers first LED light emitting unit 21, and refractive lens 32 covers second LED light emitting unit 22. In the first embodiment, the first LED light emitting unit 21 and the second LED light emitting unit 22 are each a set of a plurality of LED chips mounted on a PCB (that is, the first LED light emitting unit 21 is a set of a plurality of LED chips, and the second LED light emitting unit 22 is also a set of a plurality of LED chips), the light guide unit 31 is attached to the PCB and covers the plurality of LED chips as the first LED light emitting unit 21, and the refractive lens 32 is attached to the PCB and covers the plurality of LED chips as the second LED light emitting unit 22. And, the PCB board of the LED light source member 20 is fixedly connected to the case 10. The end of the shell 10 far away from the bulb 40 is provided with a lamp cap 50, and the lamp cap 50 is connected to a household circuit to realize electric conduction.

When the LED lamp provided by the present invention is used for lighting, the first LED lighting part 21 and the second LED lighting part 22 can be lighted and illuminate at the same time or the first LED lighting part 21 and the second LED lighting part 22 can be lighted and illuminate respectively (that is, the first LED lighting part 21 and the second LED lighting part 22 are lighted and illuminate separately and selectively according to actual needs), because the second LED lighting part 22 surrounds the first LED lighting part 21, and correspondingly, the refraction lens 32 surrounds the light guide part 31, light emitted by the first LED lighting part 21 is guided and emitted by the light guide part 31 to decorate a space, and light emitted by the second LED lighting part 22 is adjusted by the refraction lens 32 and emitted to perform main lighting on the space. When the user selects to light the first LED light emitting part 21 alone for light emission according to the requirement of indoor atmosphere decoration, the light emitted by the first LED light emitting part 21 is guided and emitted through the light guiding part 31 for decoration, so as to more vividly set up the decoration atmosphere; when a user selects to independently light the second LED light-emitting part 22 for light emission according to indoor lighting requirements, light emitted by the second LED light-emitting part 22 is adjusted by the refraction lens 32 and then emitted out for main light illumination of a space, so that wider light distribution is provided for floodlight illumination; when the first LED light emitting part 21 and the second LED light emitting part 22 are lighted to emit light simultaneously, since the luminous power of the second LED light emitting part 22 is higher than that of the first LED light emitting part 21, thus, the light emitted through the light guide of the refraction lens 32 can provide wider light distribution for floodlight illumination, and the light guide part 31 can guide out decorative decorating light in the floodlight illumination, so that the LED lamp can more vividly support the decorating atmosphere while performing floodlight illumination, and the decorative decorating light effect can be created. Like this, same LED lamp has compatible floodlight illumination function and has decorated the illumination function of spot, conveniently satisfies the user to floodlight illumination and decorate the demand of spot illumination.

In the first embodiment, the LED lamp further includes a bulb housing 40, and the bulb housing 40 is connected to the housing 10 by a snap-fit manner, so that the accommodating space 12 is formed as a closed space. The bulb shell 40 and the shell 10 are assembled in a clamping mode, so that not only is the assembling efficiency quick and convenient, but also the disassembly is convenient, and the LED lamp is convenient to maintain. The light emitted by the first LED light-emitting unit 21 is guided by the light-guiding unit 31 and emitted to the light-guiding shell 40, and then the light is emitted to the light-guiding shell 40 to decorate the space, and/or the light emitted by the second LED light-emitting unit 22 is guided by the refractive lens 32 and emitted to the light-guiding shell 40, and then the space is floodlight. The bulb shell 40 is transparent or translucent glass; alternatively, the cell 40 is a milky light transmitting cell.

As shown in fig. 1 to fig. 3, the housing 10 of the LED lamp includes an outer housing 111 and a heat-conducting inner housing 112, the outer housing 111 is made of a plastic material, the outer housing 111 serves as an outer housing, the heat-conducting inner housing 112 is sleeved inside the outer housing 111 (an outer wall of the heat-conducting inner housing 112 is in contact with an inner wall of the outer housing 111), and the heat-conducting inner housing 112 is made of a material with good heat conductivity, for example, the heat-conducting inner housing 112 is made of an aluminum material. The LED light source member 20 is disposed inside the outer case 111 and the PCB board is fixed against the open end of the heat conductive inner case 112, and the electrical components of the LED lamp are fitted in the inner cavity of the heat conductive inner case 112. Thus, during the light emitting operation of the LED lamp, the heat generated by the LED light source component 20 and the electrical components is conducted to the heat conducting inner casing 112, and finally the heat is dissipated from the outer casing 111 to the air, so as to ensure that the operating temperature of the LED lamp is not too high.

In the first embodiment, the light guide unit 31 and the refractive lens 32 are separate members. The refractive lens 32 has a central through hole, and when assembled, the light guide part 31 passes through the central through hole of the refractive lens 32 and is attached to and fixed on the PCB of the LED light source component 20, and the refractive lens 32 is directly attached to and fixed on the PCB of the LED light source component 20.

As shown in fig. 2 and 3, light guide 31 protrudes in a columnar shape from the light exit side of refractive lens 32. When the first LED light emitting unit 21 is independently turned on to emit light, since the light guiding portion 31 protrudes out of the refractive lens 32, the light emitted from the first LED light emitting unit 21 is guided by the light guiding portion 31 to emit for decoration, and the decoration light is not blocked by the surrounding refractive lens 32 to cause a shadow to affect the decoration effect. Similarly, when the first LED light emitting part 21 and the second LED light emitting part 22 are simultaneously lit to emit light, the decoration atmosphere can be more clearly baked while the floodlighting is performed, and since the light guide part 31 protrudes from the refractive lens 32, the light of the decoration is not blocked by the surrounding refractive lens 32 to cause a shadow to affect the decoration effect, and the floodlighting is performed while the lighting effect of the decoration is better created.

As shown in fig. 2 and 3, in order to diffuse the decorative lights and obtain a large decorative range, a light guiding peripheral edge 311 is disposed at one end of the light guiding portion 31 away from the LED light source member 20, and the light guiding peripheral edge 311 is disposed circumferentially around a central axis of the light guiding portion 31. Thus, the light emitted from the first LED light emitting unit 21 propagates through the light guide unit 31 and reaches the light guide peripheral edge 311, and the light is emitted after propagating through the light guide peripheral edge 311, and can be radiated to the periphery, so that a wide decorative range is obtained, and the decorative effect of the space is better.

As shown in fig. 2, on a projection plane perpendicular to the central axis of light output of the LED lamp, the projection area of the light guide peripheral edge 311 is smaller than the projection area of the refractive lens 32. That is, the range in which the light emitted from the second LED light emitting part 22 is guided and emitted through the refractive lens 32 for flood lighting is larger than the range in which the light emitted from the first LED light emitting part 21 is guided and emitted through the light guide part 31 for decoration. Not only first LED light emitting unit 21 or second LED light emitting unit 22 may be selectively and individually turned on, but also first LED light emitting unit 21 and second LED light emitting unit 22 may be simultaneously turned on. When the first LED light-emitting part 21 and the second LED light-emitting part 22 are simultaneously lightened, not only is the requirement for carrying out floodlighting on the space satisfied, but also the space is decorated and decorated simultaneously, so that the atmosphere of the space is supported.

As shown in fig. 3 and 4, the light-emitting side of the refractive lens 32 is provided with a plurality of microlenses 321, and the light emitted by the second LED light-emitting part 22 is adjusted by the plurality of microlenses 321 to emit light, so that the light of the flood lighting is softer, and is not dazzling or dazzling, and the eyes of people can be better protected from strong light stimulation.

Further, two adjacent microlenses 321 are adjacent, and the plurality of microlenses 321 are arrayed to fill the light-emitting side of the refractive lens 32, thereby more sufficiently adjusting the light emitted from the second LED light-emitting portion 22.

In the third embodiment, the light-emitting side of the refractive lens 32 is provided with a plurality of concentric circles of convex rings 322, each circle of convex rings 322 is a circle of annular lens, and each circle of annular lens refracts and guides the light emitted by the second LED light-emitting portion 22 for floodlight illumination. That is, the light emitted from the second LED light emitting unit 22 is adjusted by the plurality of circles of the convex rings 322 to emit illumination.

As shown in fig. 7 and 8, two adjacent circles of protruding rings 322 are spaced apart, and the tops of two adjacent circles of protruding rings 322 transition in a concave arc toward the lamp holder 50. So, the light-emitting curved surface of the change that the cambered surface between the evagination light-emitting curved surface of bulge loop 322 and the top of adjacent two rings of bulge loops 322 formed for the light that second LED illuminating part 22 launches is refracted the leaded light and is carried out floodlighting to the direction light-emitting of a plurality of differences, thereby obtains softer floodlighting light, and is dazzling, not dazzling, and better protection people's eyes can not receive strong light stimulation.
