In order to address this problem, most of LED is all equipped with radiator, to some extent solves the problem of heat radiation.In the structure of existing LED, LED chip is welded in a PCB by integrated, be connected with lamp holder after PCB bottom is connected with radiator, it is inner and form an airtight space that radiator is placed in lamp holder, and LED mainly relies on this confined space to dispel the heat again.The heat that LED chip produces can only flow in airtight space, can not well be dispersed into outside LED, cause the rate of heat dissipation of LED low, fundamentally can not solve the heat dissipation problem of LED.
LED light source and light fixture widely use in room lighting region, such as family, hotel, and office waits public domain.In these regions except the demand of illumination, there is the communication need to getting online without being tethered to a cable equally, although dispose wireless device at above-mentioned zone, but due to the complexity of installation site, beautiful decoration, power supply, the synthtic price index such as the cost of UNICOM's backbone network, do not obtain quorum sensing inhibitor completely in indoor, and the problem such as equipment connection number.
The solution " wireless dead angle " now occurred in the market, namely wireless signal is in the problem of in-door covering deficiency, the problem that the AP number (WAP) that wireless router provides is inadequate, substantially has following solution:
1, select to buy and router with the product of money same model, by WDS networking, the new wireless coverage that can realize ideal.
2, buy a wireless repeater, effect equals to WDS, and arranges simple, plug and play.
3, be equipped with wireless power cat, even villa or compound floor, only need the several Homeplug of over-bought can meet comprehensive covering.
But the equipment price of above solution is higher, and take multiple supply socket and space, make the usage space of average family more crowded.And, the too many inconvenience of socket and management, hiding huge potential safety hazard.
Chinese patent CN 103797641 A discloses a kind of lighting apparatus with radio-frequency antenna, and this lighting apparatus arranges the radio-frequency antenna of the Long-distance Control for lighting apparatus at the reflector place of the luminous intensity improving lighting apparatus.Radio-frequency antenna, as the support of radio-frequency antenna, is supported on enough distances of range blanking plant bottom case by reflector thus.Due to radio-frequency antenna be furnished with drive electronics, the base of radiator or any other potential interference or shield member spatially separates, so improve the radio frequency reception of lighting apparatus.But the setting of the radio-frequency antenna of this patent can only be launched or received RF signal in limited angular range, in actual use, the putting position of lamp has multiple, and the radio-frequency antenna of this patent arranges and user can be caused to use some region of wireless signal to there is signal dead angle.And radio-frequency antenna is arranged on the non-reflective place of reflector, easy and lamp holder is short-circuited, and there is potential safety hazard.In addition, it is comparatively near that radio-frequency antenna is arranged on distance light source on reflector, and light source meeting distribute heat, affects the operating efficiency of radio-frequency antenna.

Detailed description of the invention
The utility model provides a kind of LED with radio communication function, and Fig. 1 is the utility model structural representation, and as shown in Figure 1, the utility model comprises lamp holder 10, lamp housing 20, lampshade 30, surface-mounted integrated circuit and LED light source module 40.Lamp housing 20 is connected with lamp holder 10 and lampshade 30 respectively.The high heat-conducting plastic that lamp housing 20 is 10 ~ 20W/mk by thermal conductivity factor is made.Lamp housing 20 and light source base 24 carry out heat transfer by the heat-conducting layer being arranged on lamp housing 20 inside.The internal coat of lamp housing 20 has the first heat-conducting layer.Have the lamp housing of high thermal conductivity on the one hand as the operator guards of LED internal components, another aspect is as radiator.The thermal conductance that LED light source and electronic component produce by highly heat-conductive material in time, on shell, avoids too much hot-fluid to the surface-mounted integrated circuit of lamp housing inside.First heat-conducting layer adopts the highly heat-conductive materials such as aluminium, copper or graphite.
By the mode of injection mo(u)lding or cast, lamp housing 20 and the first heat-conducting layer are coupled together, first made the interior wall construction of the first heat-conducting layer by cast and machined.Then the interior wall construction of ready-made first heat-conducting layer is placed in mould, then pours into a mould the heat-conducting plastic of lamp housing 20, after solidifying, namely form the lamp design of LED.Such generation type can make seamless between lamp housing 20 and the first heat-conducting layer combining closely, and reduces the impact of thermal contact resistance on heat radiation to a great extent.High heat-conducting plastic heat radiation evenly, can be avoided scorching hot point, reduce the distortion that part Yin Gaowen causes, thus improve as the mechanical property such as intensity, stiffness.High heat-conducting plastic quality is light, is only the 50%-60% of aluminium, can reduces the quality of same volume devices.This approach reduce the thermal resistance between high heat-conducting plastic and high-thermal conductive metal material two interfaces, guarantee the smooth and easy of heat conduction.
LED light source module 40 is arranged in light source base 24, and light source base 24 is connected with the first heat-conducting layer of lamp housing 20 by the second heat-conducting layer 27.Second heat-conducting layer is inner to be arranged on lamp housing 20 around the mode of lamp housing 20 inside.Second heat-conducting layer 27 adopts the high conductive graphite with conduction orientation to be connected with light source base and electronic component heating position by the metal inner surface of lamp housing.The horizontal thermal conductivity factor of high conductive graphite is at 1000 ~ 1500W/mk, and longitudinal thermal conductivity factor, at 20 ~ 30W/mk, has the feature of the directionality heat conduction of horizontal heat conduction.Adopt high conductive graphite can make the heat of lamp housing inside lead in time lamp housing 20 and loose outwardly.The electronic component that this mode avoids in lamp housing lowers efficiency because temperature is too high or damages, thus produces the problem of communication module loss of data.
