The present disclosure relates to the field of light sources, in particular, to a light-emitting diode (LED) lamp and an LED light source module thereof.
LED light sources involve a new kind of light sources and have the advantages such as long service life, low power consumption, non-radiation, being free of harmful substances such as mercury, and so on. Lamps taking LED light sources as main light sources have been more and more in the market. The LED light sources are gradually replacing the traditional light sources, become the important light sources in the lighting field, and are widely applied in various fields of life and production.
A plurality of LED units are usually integrated onto a printed circuit board (PCB), and a separate lens unit respectively covers each LED unit. The means that a plurality of lens units are respectively arranged on a light source plate, which wastes time and work and also cannot guarantee quality. Moreover, the arrangement of the separate lens units also requires a protecting cover that is additionally arranged to protect circuits on parts of the light source plate, which part is not covered by the lens units, so the manufacturing process is relatively complex.
In addition, the assembly of LED light sources into a lamp is a necessary process in the manufacturing process, and the assembly efficiency also affects the cost of the lamp. The fixing means mostly directly employs screws to fix a light source module on a base. The fixing means is inconvenient in the assembly and disassembly process. There is also disclosed a structure adopting magnetic connecting elements to adsorb the entire lamp onto a fixing mechanism. Although the convenience in the assembly process is improved to some extent, the structure still suffers from the risk of disengagement of the magnetic elements and the lamp.
Therefore, an LED lamp having the advantages of simple manufacturing process, easy assembly, safety and reliability and an LED light source module applied in the LED lamp are required.
An objective of the present disclosure is to provide an LED lamp and an LED light source module applied in the LED lamp.
The first aspect of the present disclosure discloses an LED light source module.

The integrated lens assembly may cover an outside of the first surface of the light source plate, and may be provided with a plurality of lens units which may respectively cover an outside of corresponding LED light sources, and may be provided with an accommodating space which may be configured to accommodate the power driving module into the accommodating space.
The second aspect of the present disclosure discloses an LED lamp light source module, disposed in an LED lamp and used for lighting. The module may include a light source plate including a first surface and a second surface which are opposite to each other, in which a plurality of LED light sources are attached to the first surface, and the second surface faces a base assembled on a mounting base of the LED lamp; a power driving module electrically connected with the light source plate; and an integrated lens assembly configured to be fixed with the light source plate.
Further, the module may include at least two magnetic elements assembled into the integrated lens assembly, in which the integrated lens assembly is at least partially bonded to and covers an outside of the first surface of the light source plate and is provided with a plurality of lens units which respectively cover an outside of corresponding LED light sources; the integrated lens assembly may be provided with an accommodating space, and the power driving module is accommodated into the accommodating space; the integrated lens assembly is provided with accommodating portions which are extended towards the light source plate and run through the light source plate; and the at least two magnetic elements are at least partially accommodated into the accommodating portions.

Preferably, in the present disclosure, the integrated lens assembly 20 covers the outside of the first surface of the light source plate 10 and is provided with a plurality of lens units (e.g., hemispherical lenses 24) which respectively cover the outside of LED light sources 11; the integrated lens assembly 20 is provided with an accommodating space 25; and the power driving module 40 is accommodated within the accommodating space 25. In general, the integrated lens assembly 20 is made from an insulating material, preferably one of polycarbonate (PC), Acrylic or polymethyl methacrylate (PMMA). The three kinds of materials have the advantages of light weight, low cost and high transmittance and are relatively ideal materials taken as light guide components. As the power driving module 40 is accommodated into the accommodating space 25, the power driving module 40 can be insulated from the outside space through the integrated lens assembly 20, and the integrated lens assembly 20 is taken as a protecting cover and configured to protect the power driving module 40. In the present disclosure, the integrated lens assembly 20 receives emergent light of the light source plate 10. By adoption of the LED light sources 11 and the hemispherical lenses 24 which are arranged in one-to-one correspondence, the emergent light is refracted by the hemispherical lenses 24 and emitted to form scattered luminous spots, so that the function of lighting can be achieved.
In the two preferred embodiments, the integrated lens assembly 20 is equipped with a lens setting area provided with the plurality of hemispherical lenses 24 and a power supply accommodating area provided with the accommodating space 25 and configured to accommodate the power driving module 40; the lens setting area is disposed at the first height of the integrated lens assembly 20; and the power supply accommodating area is formed with being projected upwards from the first height, and a top surface of the power supply accommodating area is disposed at the second height. Due to the lens setting area and the power supply accommodating area with different heights, the integrated lens assembly 20 is L-shaped as a whole, and the power supply accommodating area higher than the lens setting area provides convenience to form the accommodating space 25 to accommodate the power driving module 40. The power supply accommodating area extends outward to integrally form a tail portion 253, and the height of the tail portion is lower than the second height where the power supply accommodating area is provided.
The tail portion 253 may be configured to allow a wire to pass therethrough and clamp the wire so as to prevent the wire electrically connected with the power driving module from being electrically disconnected from the power driving module because of pulling. The tail portion 253 is overlapped with the light source plate 10 and provided with two openings 2530, which allow screws to pass therethrough to clamp the wire between the integrated lens assembly 20 and the light source plate 10. Close to the tail portion 253, the integrated lens assembly 20 is provided with an notch 252 and the light source plate 10 is provided with a notch 10 which is open upward and downward. The notches 252, 14 are configured to allow the wire to be electrically connected with an external power source by passing through the light source plate 10 from the integrated lens assembly 20.
Preferably, corresponding to the integrated lens assembly 20, the light source plate 10 is provided with a light source setting area provided with the plurality of LED light sources and a power supply area configured to mount the power driving module 40. The lens setting area covers the light source setting area, and the power supply area and the power supply accommodating area accommodate the power driving module 40 together. In the first preferred embodiment, the power supply accommodating area is disposed on one side of the lens setting area, and correspondingly the power supply area is disposed on one side of the light source setting area. In the second preferred embodiment, the power supply accommodating area is disposed in the middle part of the lens setting area, and correspondingly the power supply area is disposed in the middle part of the light source setting area. In the two optional preferred embodiments, both the two positions do not affect the luminous effect of the lamp, and the insulating effect of the power driving module 40 is also pretty good.
In the two preferred embodiments, a plurality of magnetic elements 30 and/or mechanical connecting elements (not shown, for example screws, in which case the integrated lens assembly 20 and the light source plate 10 are correspondingly provided with screw holes (not shown in the figure)) run through the integrated lens assembly 20 and the light source plate 10, and are adsorbed and/or assembled onto the base. Preferably, the plurality of magnetic elements 30 and/or mechanical connecting elements are concentrically spaced on a central portion and/or a body portion and/or an edge portion of the integrated lens assembly 20; and the light source plate 10 is correspondingly provided with through holes 12 with a shape matching with the magnetic elements 30 and/or the mechanical connecting elements to run there through and thus be fixed.
In the first preferred embodiment, two magnetic elements 30 are respectively disposed at the central portion of the lens setting area and the central portion of the junction between the lens setting area and the power supply accommodating area; and the two magnetic elements 30 respectively fix the lens setting area and the power supply accommodating area. In the second preferred embodiment, three magnetic elements 30 are approximately distributed in a triangle, and the fixing effect can become better by utilization of the stability of the triangle.
The integrated lens assembly 20 includes a plurality of accommodating portions 21. The accommodating portions 21 are extended towards the light source plate 10 from the integrated lens assembly 20. Correspondingly, the light source plate 10 is provided with a plurality of through holes 12. The through holes 12 and the accommodating portions 21 are arranged correspondingly and have shapes matching each other, namely the accommodating portions 21 and the through holes 12 are in the same number; the accommodating portion 21 can just run through the through hole 12; and an outer wall of the accommodating portion 21 and an inner wall of the through hole 12 generate frictional contact therebetween. One magnetic element 30 is fixed in each accommodating portion 21; and meanwhile, the base of the lamp can adsorb the magnetic elements 30 disposed in the accommodating portions 21, and the accommodating portion 21 is attracted to the magnetic base as well. In this way, the integrated lens assembly 20 and the light source plate 10 are fixed on the magnetic base.
In the present disclosure, the fixing effect of the LED light sources and the lamp can be achieved simply by adoption of the structure of the accommodating portions 21 and the through holes 12 provided on two components of the LED light source module, namely the light source plate 10 and the integrated lens assembly 20, with the magnetic elements 30 being inserted into the accommodating portions 21, and by utilization of magnetic attraction between the magnetic elements 30 and the magnetic base without additional assembling tools (e.g., screws and a screw driver), so that the assembly process can become more convenient. Meanwhile, the light source plate 10 and the magnetic base of the lamp are not isolated from each other by other component(s), and the thermal conductivity of general magnetic materials is also good, so that the thermal radiating effect of the entire lamp is relatively good.

In the second preferred embodiment, four pair of elastic jaws 27 are adopted, and the elastic jaws 27 are disposed on the lens setting area of the integrated lens assembly 20 to approximately form a square.
The fixing means of adopting the mechanical connecting elements such as the elastic jaws 27 and the elastic fasteners 26 is an exemplary assembly method in consideration of both convenience and reliability. It should be conceived by those skilled in the art that the integrated lens assembly 20 and the light source plate 10 can also be fixed by various other common fixing means, for instance, fixing via a U-shaped clamp plate; the present disclosure only exemplifies two preferred fixing means; and the fixing of the integrated lens assembly 20 and the light source plate 10 by other fixing means shall obviously fall within the scope of protection of the present disclosure.

The integrated lens assembly 20 and the light source plate 10 are fixedly connected by a detachable connection mechanism such as elastic fasteners 26 and elastic jaws 27 at first, and then fixed by means of the magnetic force of the magnetic elements 30 fixed within the accommodating portions 21 and the magnetic base of the lamp, so that the entire integrated lens assembly 20 and the light source plate 10 can be fixed on the magnetic base of the lamp. The LED lamp adopting the above fixing structure has a very easy assembly process. Moreover, due to the further cooperation of the magnetic elements 30 and/or the elastic fasteners 24 and/or the elastic jaws 25, the structure of the LED lamp is very safe and reliable.
