Abstract
The invention discloses a graphite light-emitting diode (LED) device, which comprises a circuit board, wherein a luminous chip is electrically connected with the circuit board or a plurality of luminous chips are integrated on the circuit board, and packaging portions are packaged on the luminous chip or the plurality of luminous chips which is/are directly arranged on a graphite radiator. According to the graphite LED device (with a single chip or integrated chips), the luminous chip(s) is/are directly fixed on the graphite radiator, so that several layers of thermal resistances are reduced when the device is compared with common LED devices, the heat can be dissipated more quickly, the LED device is more persistent and stable, the light attenuation is slowed down, the service life is prolonged, and the weight of the whole device is lighter due to removal of a light source support, a printed circuit board (PCB) or an aluminum substrate.
Description
Technical field
The invention belongs to LED device light source field.
Background technology
The structure of the light fixture that existing LED device is formed is as shown in Figure 1; Comprise a wiring board, said wiring board top is provided with a light source bracket, and said light source bracket is provided with luminescence chip; Be packaged with packed part on the said luminescence chip; And playing the effect of heat radiation through the below that Aluminium Radiator is arranged on wiring board, the LED device architecture complicacy of this kind structure, shape-designing limitation, heat dispersion are general, and weight is bigger.
Summary of the invention
For overcoming deficiency of the prior art, the object of the present invention is to provide a kind of graphite LED device of simple in structure, good heat dissipation effect.
For realizing above-mentioned technical purpose, for reaching above-mentioned technique effect, the present invention realizes through following concrete technical scheme:
The hot coefficient of the conduction of graphite is up to 2156W/K.M, considerably beyond materials such as copper aluminium, graphite product in the process of taking away the heater heat to product in the performance of other components and parts can not have any impact, be applicable to and make various radiating elements.
A kind of graphite LED device; Comprise a wiring board; Be electrically connected with a luminescence chip on the said wiring board or be integrated with some luminescence chips, be packaged with packed part on described one or some luminescence chips, described one or some luminescence chips are set directly on the heat radiator.
Compared with prior art, beneficial effect of the present invention is:
1, graphite LED device of the present invention (single or integrated) is directly luminescence chip to be fixed on the heat radiator; Reduced by several layers of thermal resistance than common LED device, thereby can heat have been shed faster, the more effective LED device that makes is lasting and stable; Slow down light decay; Life-saving, and owing to saved light source bracket, PCB or aluminium base, the weight of integral device is lighter relatively;
2, graphite LED device of the present invention is as led light source device independently; The identical element sectional area is little, volume is little; The multiple unit combination selection is free, is installed in easily on the carrying platform that is reserved with pilot hole, processes regular lighting; Increase the degree of freedom of shape-designing, the user can freely assemble according to the demand of using;
3, graphite LED device of the present invention can make luminescence chip be controlled in the safe temperature; Keep light efficiency, increase reliability reduction maintenance cost; Make the result of use and the useful life of high-power LED lighting fixture operate as normal can be because of bad not being affected of dispelling the heat; Be applicable to 1W, 3W, 5W, 10W, even 100W or above high-power LED lighting fixture.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. specify as after.Embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
