Description

LED light source

Technical Field

The application relates to the field of LEDs, in particular to an LED light source.

Background

In the context of energy shortages and environmental protection, there is a growing need for lighting solutions that are more energy efficient and have a longer lifetime. Conventional incandescent and fluorescent lamps have problems of energy waste and pollution, which motivates scientists and engineers to find more sustainable lighting technologies. With the continued development of semiconductor technology, semiconductor materials and fabrication processes have become more mature and controllable. This provides a technical basis for the manufacture and application of LEDs. The research of photoelectric effect enables scientists to better understand the phenomenon that a semiconductor material emits light when electrons and holes are combined, and provides a basis for the principle of an LED. Quantum effects are a key principle of LED operation, and research on quantum effects by scientists enables them to design efficient and stable light emitting diodes. In some poor areas, the lighting resources are insufficient, and conventional lighting equipment is expensive and not sustainable. LEDs have become a potential choice for meeting the lighting needs of these areas as an efficient, durable, and low-energy lighting technology. The advent of LED lamps is due to a common impact on energy efficiency, environmental protection and technical development. The need for better lighting solutions, advances in the fields of semiconductor technology, optical theory, etc., have jointly driven the development and application of LED lamps as a high-efficiency, long-life, sustainable lighting technology. Because the LED lamp is too small in size during manufacturing, the brightness of the LED lamp is insufficient, and the lighting effect is poor.

In the prior art, as in CN111081690a, the brightness of the LED light source is increased by adding phosphor bodies to the light source, but the phosphor conversion process introduces energy loss. Part of the blue light is used to excite the phosphor, and thus the overall light output efficiency may be reduced.

Some embodiments of the present application are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.

An LED light source 100, comprising;

a housing 10 including a first insulating case 11 and a second insulating case 12 provided on the first insulating case 11;

the LED lamp 20 is arranged in the second insulating shell 12 and is used for emitting light from a lamp source;

the light focusing layer 30 is arranged between the second insulating shell 12 and the LED lamp 20 and is used for reflecting light rays emitted by the LED lamp 20;

the light collecting ring 40 is disposed in the second insulating shell 12 and is located on the LED lamp 20, towards the direction of the light collecting layer 30, the light collecting ring 40 is in a conical ring structure, the conical opening is gradually reduced, the light collecting ring 40 comprises a layer of light collecting coating, and the light collecting coating is disposed on the annular wall of the light collecting ring 40 and is used for collecting light rays of the LED lamp 20.

When the LED lamp 20 emits light, the light is reflected by the light-condensing layer 30, and then is collected and guided by the light-condensing coating in the light-condensing ring 40, so as to form a more concentrated light beam. This process allows more light to be concentrated and focused, thereby improving the effect and brightness of the illumination. The design of such LED light sources 100 makes them suitable for scenes requiring high brightness and focused illumination, such as stage lighting, display presentations, road lighting, etc. By the design of the light-gathering layer 30 and the light-gathering ring 40, the light source can achieve more accurate irradiation effect, concentrate light rays in a specific area, and provide better illumination effect and energy utilization rate.

Referring to fig. 1-3, an embodiment of the present application provides an LED light source 100, including: a housing 10 including a first insulating case 11 and a second insulating case 12 provided on the first insulating case 11; the LED lamp 20 is arranged in the second insulating shell 12 and is used for emitting light from a lamp source; the light focusing layer 30 is arranged between the second insulating shell 12 and the LED lamp 20 and is used for reflecting light rays emitted by the LED lamp 20; the light collecting ring 40 is disposed in the second insulating shell 12 and is located on the LED lamp 20, towards the direction of the light collecting layer 30, the light collecting ring 40 is in a conical ring structure, the conical opening is gradually reduced, the light collecting ring 40 comprises a layer of light collecting coating, and the light collecting coating is disposed on the annular wall of the light collecting ring 40 and is used for collecting light rays of the LED lamp 20.

Specifically, the housing 10 is an external protection structure of the entire LED light source 100, and also plays a role in isolation and insulation, so as to ensure that the normal operation of the LED light source 100 is not affected by external environment. The first insulating case 11 and the second insulating case 12 together constitute an insulating case structure of the case 10, preventing current leakage and short circuit. The LED lamp 20 is a core component of a light source, which can produce a luminous effect by current excitation. By the discharge process, the light generated by the LED may provide a desired spectrum for illumination, display, etc. The condensing layer 30 is positioned between the LED lamp 20 and the second insulating case 12, and focuses and orients light emitted from the LED lamp 20 by reflection and refraction, thereby achieving a more precise lighting effect. The condensing layer 30 can improve brightness and a throw distance of light. The tapered configuration of the light gathering ring 40 concentrates the light from the LED lamp 20 into a more intense beam. The light-gathering coating further enhances the light gathering effect, thereby providing higher brightness in specific illumination areas.

Further, when current passes through the LED lamp 20, the LED lamp 20 generates light. These rays are first guided and gradually concentrated by the light-collecting ring 40, and then repeatedly reflected in the light-collecting layer 30 by reflection and refraction of the light-collecting coating, to finally form a focused light beam in a specific direction. The light-gathering layer 30 serves to reflect and direct light into a specific illumination area.

In a specific embodiment, the second insulating housing 12 is in a tapered annular structure toward the light-condensing layer 30, and the tapered opening is gradually increased.

In particular, this feature ensures a geometrical configuration between the second insulating shell 12 and the light-condensing layer 30, i.e. the orientation of the second insulating shell 12. The purpose of this arrangement is to optimise the reflection and concentration of light, to ensure maximum efficiency of light transmission from the LED lamp 20 to the light-gathering layer 30, and the design of the second insulating housing 12 is a tapered annular structure, meaning that it resembles an inverted cone, gradually widening in direction from the LED lamp 20 to the light-gathering layer 30. This particular shape may direct the reflected light to spread gradually, thereby increasing the angle of the light beam so that the light emitted from the light source better covers the target area.

Further, when the LED lamp 20 emits light, the light first passes through the second insulating case 12 and then is reflected in its tapered structure. As the tapered opening increases, the angle of spread of the light increases. These reflected light rays then enter the condensing layer 30 and are further condensed and directed by the condensing coating to form a more wide-angle, focused beam.

In one embodiment, the second insulating housing 12 includes an adhesive layer 121, and the adhesive layer 121 is disposed on the first insulating housing 11.

Specifically, the adhesive layer 121 is disposed on the first insulating housing 11, and firmly adheres the first insulating housing 11 and the second insulating housing 12 together, ensuring that the connection therebetween is firmly not loosened. The design increases the overall structural stability of the light source, prevents separation or loosening during transportation, installation and use, and thereby extends the life of the light source. The adhesive layer 121 may also prevent dust and moisture from penetrating into a gap between the first and second insulating cases 11 and 12 to some extent, protecting components inside the LED light source 100 from the external environment. Further, an adhesive layer 121 is added to the first insulating case 11 at an appropriate position during the manufacturing process. The second insulating case 12 is then placed on the adhesive layer 121 so as to be firmly adhered to the adhesive layer 121. This process is performed under appropriate temperature and pressure conditions to ensure a firm connection between the adhesive layer 121 and the insulating shell. A stable connection between the first and second insulating cases 11 and 12 is ensured while providing additional fixation and support to enhance structural stability and durability of the LED light source 100.

In one embodiment, the adhesive layer 121 is a double sided tape.

Specifically, the double-sided tape as the material of the adhesive layer 121 can form a strong adhesive effect between the two surfaces, ensuring that the adhesive layer 121 is firmly attached to the insulating case to prevent separation or loosening. The stable adhesion of the double-sided tape between the two insulating cases can enhance the structural stability of the entire light source, making it less susceptible to vibration or external impact during long-term use. The use of the double-sided tape can simplify the manufacturing process because it does not require a coating and drying step like a liquid adhesive, thereby improving the production efficiency. Further, during the manufacturing process, the double-sided tape is cut into an appropriate shape and size in advance and then placed on the first insulating housing 11. Next, the second insulating case 12 is placed on the double-sided adhesive tape, so that a firm connection is formed between the two insulating cases. This process is typically performed under appropriate temperature and pressure conditions to ensure that the double-sided tape is able to firmly adhere to the insulating housing. The first insulating case 11 and the second insulating case 12 can be firmly coupled together while providing additional support and fixation, thereby enhancing structural stability and durability of the LED light source 100.

In one embodiment, the first insulating housing 11 includes a heat dissipation layer 111, and the heat dissipation layer 111 is disposed under the light condensation layer 30 for dissipating heat.

Specifically, the heat dissipation layer 111 enables heat generated by the LED to be conducted to the external environment more quickly, so that the temperature of the LED lamp 20 is reduced, and the influence of excessive temperature on the performance of the light source is avoided. By maintaining the temperature of the source of the LED lamp 20 within a suitable range, the heat sink 111 may reduce the rate of thermal decay of the LED, thereby extending the life of the LED light source 100. Maintaining a stable operating temperature may improve the stability of the LED light source 100, ensuring the consistency and reliability of its output light. Further, in the design of the LED light source 100, the heat dissipation layer 111 is typically made of a material with high thermal conductivity, such as a thermally conductive silicone. This material has excellent heat conduction properties and can rapidly transfer heat generated from the LED lamp 20 source to the surface of the heat dissipation layer 111. Once the heat is transferred to the surface of the heat sink 111, it radiates heat to the surrounding environment by radiation, conduction, convection, etc., thereby reducing the temperature of the LED lamp 20 source. The generated heat is effectively conducted away from the LED lamp 20 source to maintain the operating temperature of the LED, avoid overheating, and improve the life and performance of the light source.

In an embodiment, the heat dissipation layer 111 is a thermally conductive silica gel

In particular, the LED lamp 20 generates heat during operation, and if proper heat dissipation is not performed, an increase in temperature may result in performance degradation and a shortened lifetime. The thermally conductive silicone heat dissipation layer 111 can effectively disperse heat from the LED lamp 20 to the surface of the heat dissipation layer 111 and then further to the surrounding environment. By controlling the operating temperature of the LED lamp 20, the optimum operating state thereof can be maintained, and the light efficiency and stability can be improved. The high thermal conductivity of the thermally conductive silicone can help to transfer heat rapidly to the surface of the heat sink 111, thereby reducing the temperature of the LED lamp 20. Maintaining an appropriate operating temperature may slow the aging rate of the LED elements, thereby extending the useful life of the LED light source 100. Further, the heat conductive silicone is generally a material having good heat conductivity, and is coated or fixed on the back or side of the LED lamp 20, in direct contact with the heat dissipation layer 111. When the LED lamp 20 starts to operate and generates heat, the heat-conductive silicone rapidly conducts the heat to the surface of the heat dissipation layer 111. The heat sink 111 may then dissipate heat to the surrounding environment by natural convection, conduction, or radiation.

In one embodiment, the first insulating housing 11 includes a power interface 112, and the power interface 112 is disposed on an end surface of the first insulating housing 11.

In particular, this design has a clear role and advantage in the location and installation of the power interface 112. The power interface 112 is provided at the end face of the first insulating housing 11 so that a user can easily connect or disconnect the power without turning on the outer housing of the entire light source. This provides a more convenient way of operation and maintenance. Placing the power interface 112 on the end face of the first insulating housing 11 helps to isolate the power cord and power components from other internal structures, improving the safety of the overall LED light source 100. This design allows a more compact layout of the power lines, thereby saving space and providing a cleaner overall appearance of the light source. Further, the user needs to plug a power cord into the power interface 112 to connect the LED light source 100 with an external power source. Because the power interface 112 is located on the end face of the first insulating housing 11, a user can conveniently plug the power cord without opening the light source housing, so as to realize the starting and the closing of the LED light source 100. The connection and maintenance of the LED light source 100 is more convenient while improving the safety and the neatness of the external appearance, and is suitable for various lighting applications requiring frequent operation of power connection.

In one embodiment, two power interfaces 112 are provided, and two power interfaces 112 are provided on the end face of the first insulating housing 11, so as to improve illumination.

Specifically, to improve the lighting effect and flexibility. In some cases, a single power interface 112 may not provide sufficient current to affect the light intensity and illumination uniformity of the LED lamp 20. By providing two power interfaces 112, currents can be provided separately, thereby ensuring uniformity of illumination and avoiding uneven distribution of light. Connecting the power interface 112 to two power sources, respectively, may better distribute the current load, reduce the load on the power interface 112 and wires, and thereby improve the stability and lifetime of the overall LED light source 100 system. In some applications, a backup power source may be required to ensure continuous illumination. The provision of two power interfaces 112 allows switching to another alternate power source in the event of a power failure, maintaining the sustainability of the illumination. Further, two power interfaces 112 are provided on the end face of the first insulating housing 11, and a user can insert power lines into the two interfaces, respectively. When both power interfaces 112 are connected to a power source, the LED light source 100 will obtain a larger current supply, improving the light emission luminance. The user may connect both power interfaces 112 at the same time when a backup power supply or better current distribution is desired. The LED light source 100 has improved illumination effect, flexibility and stability, and is suitable for application scenes requiring high-load illumination or standby power.

In one embodiment, the light-focusing layer 30 is a tinfoil layer.

Specifically, the tinfoil layer is used as the light-condensing layer 30, has good reflection characteristics, and can effectively reflect and condense the light emitted by the LED lamp 20, thereby enhancing the illumination effect. The reflection performance of the tin paper layer is helpful for concentrating light rays in the area to be illuminated, and the illumination brightness and uniformity are improved. Because the tin paper layer can effectively collect light, the light is more concentrated, and thus, higher illumination effect is realized under the same light source. This helps to save energy and reduce energy consumption. The reflection performance of the tin paper layer can help control the directivity of light rays, focus the light rays on a specific area, and is suitable for scenes needing targeted illumination. Further, the tinfoil layer is located between the LED lamp 20 and the second insulating case 12 as the light-condensing layer 30, and when the LED lamp 20 emits light, the tinfoil layer reflects and condenses the light, so that the light is more intensively irradiated to a specific area, and the lighting effect is improved.

In one embodiment, a convex lens is disposed between the second insulating housing 12 and the light collecting ring 40 for collecting light.

Specifically, the convex lens can focus light to a smaller area, so that the light is more concentrated, and the lighting effect is enhanced. The light can be more concentrated through the lens effect of the convex lens, and the illumination brightness is improved. The convex lens can change the incident angle and the emergent angle of the light, so that the light is more intensively irradiated to the area to be illuminated, thereby optimizing the illumination angle and the uniformity. The convex lens can effectively focus scattered light, so that light loss is reduced, the light utilization rate is improved, and a more efficient illumination effect is realized. Further, when the LED lamp 20 emits light, the light passes through the convex lens, and the convex lens focuses the light through the lens effect, so that the light is more concentrated, and then reflected and concentrated by the light-concentrating ring 40, thereby further enhancing the illumination effect. Light focusing, improving irradiation angle, improving light utilization rate, and enhancing LED.

The foregoing is merely exemplary of the present application and it should be noted herein that modifications may be made by those skilled in the art without departing from the inventive concept herein, which fall within the scope of the present application.
