Abstract
The utility model relates to a LED encapsulation illumination field especially relates to a light -emitting diode (LED) tube lamp, and mainly include radiator, lamp body, floodlight board, LED light source module and connect wires outward, LED light source module fixes the terminal surface at the radiator, the one end that the radiator was fixed with LED light source module is connected with the lamp body, floodlight board is installed in the lamp body, connect wires outward. Compared with the prior art, the beneficial effects of the utility model are that: the heat dissipation is fast, and the light -emitting is even, realized in the configuration of the same physical space more high -power, the output of higher lumen.
Description
Technical field
The utility model relates to LED lighting field, particularly relates to a kind of LED down.
Background technology
Down lamp is generally applied to the room lightings such as market, office, factory, hospital, simple and conveniently to be liked by people because it is installed.Early stage LED down is due to the costliness of LED lamp bead, and holistic cost is very high not by client is accepted.In recent years, along with the reduction of LED down chip price and the raising of heat dissipation technology, solid basis has been established in the development for LED down.
But for Down lamp lamp pearl, should adopt high-power lamp pearl, should not adopt small light pearl, tracing it to its cause is that generally to irradiate vertical range be 4-5 rice to LED down, small light pearly-lustre intensity can not meet lighting demand, even if large-power LED light bead also seems, catching elbow sees the flap.In addition, high-powerly also represent high heat, if heat can not distribute in time, LED will produce light decay, and aberration finally causes necrosis.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of power large and the LED down of good heat dissipation effect.
For achieving the above object, the utility model can be achieved by the following technical programs:
A kind of LED down, comprise radiator, lamp body, floodlight plate, LED light source module and external cord, described LED light source module is fixed on an end face of radiator, one end that described radiator is fixed with LED light source module is connected with lamp body, described floodlight plate is arranged in lamp body, and described external cord is connected with LED light source module.
Further, described radiator is heronsbill structure, increases radiator and extraneous heat-exchange capacity.
Further, described LED light source module comprises substrate and LED chip, multiple LED chip high density is fixing on the surface of the substrate, described LED chip surface is provided with fluorescent coating, LED chip more than can arranging in less physical space as far as possible, obtain the output of more high-power, larger lumen, and bright dipping is more even.
Further, described LED chip is seven, and wherein six are arranged into regular hexagon shape, and the surplus next one is positioned at regular hexagon center.
Further, described LED chip adopts the welding of upside-down mounting die bond technique on the surface of the substrate.
Further, the specification of described LED chip is 1.6 × 1.6mm
2, much smaller than current LED chip specification.
Further, the material of described substrate is the aluminium nitride ceramics with LED chip similar thermal expansion coefficient, improves the heat-sinking capability of LED light source module.
Compared with prior art, the beneficial effects of the utility model are: rapid heat dissipation, uniform in light emission, and same physical space configuration achieves more high-power, higher lumen exports.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is further described:
As shown in Fig. 1 ~ 2, LED down described in the utility model, mainly comprises radiator 2, lamp body 3, floodlight plate 1, LED light source module 5 and external cord 4.LED light source module 5 is fixed on the end face of wherein one end of radiator 2, and this end that radiator 2 is fixed with LED light source module 5 is connected with lamp body 3, and floodlight plate 1 is arranged in lamp body 3, has the effect of optically focused.External cord 4 is connected with LED light source module 5, exports from radiator 2 tail end.
As shown in Figure 3, LED light source module 5 comprises substrate 502, LED chip 501 and fluorescent coating 503, and LED light source is that multiple LED chip 501 adopts upside-down mounting die bond technique to be welded in substrate 502 surface, and wherein LED chip 501 dimensions is 1.6 × 1.6mm
2and Small Distance high-density arrangement, LED chip 501 surface is provided with fluorescent coating 503.The material of substrate 502 is the aluminium nitride ceramics with LED chip 501 similar thermal expansion coefficient, improves the heat-sinking capability of LED light source module 5.
As shown in Figure 2, radiator 2 adopts heronsbill structure, and LED chip 501 number be arranged on substrate 502 is seven, and wherein six arrangements are in regular hexagon shape, and the surplus next one is positioned at this regular hexagon center.This arrangement more can coordinate lamp body 3 to send uniform light.
For a person skilled in the art, according to above technical scheme and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection domain of the utility model claim.
