Abstract
The utility model provides an LED illumination device and a radiating structure thereof. The LED illumination device comprises a protective cover plate, an LED illumination module consisting of an LED substrate and LED particles, and a lamp combined by a transparent plate and connected with a power supply; the transparent plate and the protective cover plate form a box type structure, and the LED substrate is fixedly arranged at the middle; every 3-10 LED particles are connected into a group of LEDs in series to be fixedly welded on the LED substrate; the inner side of the emergent light wall of the transparent plate is pasted with a scattered light membrane and the inner side of the enclosure wall of the transparent plate is provided with a reflective layer; and light rays emitted by the LED illumination module can be uniformly and softly emitted towards the direction needing illumination after being subjected to scattering process by the transparent plate. The utility model further provides a radiating structure applicable to the LED illumination device, which comprises a substrate, the LED particles and cladding copper (or cladding aluminum) at the front surface and the back surface of the substrate. The utility model has good radiating effect, low cost, energy conservation and environmental protection and long service life of the LED, and can fully meet the promotion and application of LEDs with different power.
Description
Technical field
The utility model relates to a kind of LED lighting device and radiator structure thereof, is applicable to any place that needs illumination, and described radiator structure is applicable to small-power or high-power LED illumination respectively.
Background technology
Lighting device is basic facilities, and the light source that adopts is powerful fluorescent lamp, incandescent lamp, Halogen lamp LED etc. usually.Adopt the shortcoming of real light source to be: 1, fluorescent tube is very easily broken in transportation and installation process, and it is many unfavorable to bring to construction; 2, the high percentage of damage of fluorescent tube increases the cost that uses; 3, the life-span of real light source generally shorter, need frequent replacing fluorescent tube, the general incandescent lamp continuous operation life-span is about 1200 hours, fluorescent lamp and Halogen lamp LED continuous operation life-span are about 3000 hours; 4, present lighting source is that the rectifier of the operating mode that is unsuitable for frequent key lamp, particularly fluorescent lamp damages easily, changes fluorescent tube regularly and safeguards required expense height; 5, for fluorescent lamp lighting, also need high pressure to start, and start to illumination and need the regular hour, efficient is low, power consumption is big, and contains mercury in the fluorescent lamp, and environment is had certain pollution, also is the known shortcomings of people.For this reason, the technical staff seeking always a kind of environmental protection, energy-conservation, can adapt to the desirable lighting device of working in regular switch and the dynamic environment.
In recent years, along with improving constantly of LED light efficiency, led light source begins progressively to advance people's lighting field.Semiconductor lighting is with characteristics such as its energy-saving and environmental protection, long-lives, be acknowledged as the third generation light source after incandescent lamp, fluorescent lamp, nowadays, single LEDs from several milliwatts to several watts has been widely used in the different lighting devices, but heat dissipation problem still exists, and heat radiation is maximum and the most serious problem in the more powerful lighting device of plurality of LEDs composition.
Current in the application of low-power LED, for saving cost, do not adopt heat dissipation design usually.General low-power LED all is as substrate with pcb board, pcb board generally constitutes with raw material such as organic resins, and directly on pcb board, connect up, there is not radiating treatment, this pcb board thermal conductivity is bad, when using for the LED of meeting heating, heat is difficult for distributing, and causes the LED junction temperature to raise, and directly has influence on the light efficiency of LED, quickened its light decay, LED reduces service life.In recent years, the aluminium base that adopted that has is made the LED substrate, and it helps the heat radiation of LED, but higher because of the aluminium base price, is not suitable for low-power LED, is limited to cost factor and can't widelys popularize application on market.For great power LED, generally adopt printed circuit on the aluminium base at present, by the external radiator heat radiation, owing on the aluminium base insulating barrier is arranged, thermal resistance is also bigger again, and such way can not reach best heat-conducting effect.
Chinese patent by retrieval, the more existing inventions of the application of relevant LED illumination, but their connection arrangement is different with the present invention, be not provided with radiator structure yet, all can not satisfy LED operating efficiency, function and the service life of realizing and on market, widely popularize application, and can not solve the technical problem that existing lighting device exists.
The utility model content
The purpose of this utility model is intended to solve the problem that prior art exists, a kind of LED lighting device and radiator structure thereof are provided, described LED lighting device can be applicable to any place that needs illumination, have energy-conservation, illumination is evenly soft, the radiator structure of design can be useful in respectively on small-power or the high-power LED lighting device.The LED lighting device that provides has that energy consumption is low, the life-span is long, toggle speed is fast, mechanical strength is high, environment friendly and pollution-free characteristics.The radiator structure of the present invention's design, do not need to increase in addition radiator and just can realize extraordinary heat sinking function, make that the LED lighting device has more high efficiency, LED good heat dissipation effect, cost is low, the life-span is long, fully satisfy applying of various different capacity LED.
Concrete technical scheme of the present utility model label in conjunction with the accompanying drawings is described below: a kind of LED lighting device; comprise; cover sheet 2, by LED substrate 3 or claim printed circuit board (PCB) and LED light emitting module and light-passing board 5 that LED particle 4 constitutes are combined into light fixture 6; and be connected with power supply; lighting device is fixed on the connecting plate 1
Described light-passing board 5 and described cover sheet 2 constitute a box body formula structure, and center fixed is arranged LED substrate 3;
Described LED light emitting module is as illuminator, and the operating voltage of single LEDs particle 4 is 2.8～4V, and operating current is 15～100mA;
Described LED particle 4 is connected into one group of LED for per 3～10, at least one group of above composition one lighting source parallel with one another, and solid welding is on LED substrate 3,
Described power supply is that operating voltage is the constant-current supply of 24V, offers the LED power supply of each group;
Described LED light emitting module, luminous efficiency reaches more than the 50lm/W;
