Embodiment 2
The present embodiment is only described the embodiment part different from embodiment 1, and identical embodiment part repeats no more.Compare with embodiment 1, the present embodiment 2 has set up outer casing 26 outside lamp housing.
Outer casing structure as shown in Figure 2.Be arranged with in the mode of surrounding lamp housing the outer casing 26 that longitudinal size is significantly less than lamp housing in the outside of close LED light source module 40 one end of lamp housing 20.Be separated with between outer casing 26 and lamp housing 20 and be enough to containing antenna and allow cross-ventilated space, outer casing 26 two ends, the antenna being arranged on lamp housing outer surface is in dry environment all the time.
When LED illumination device works, the temperature of lamp housing is higher than the temperature of indoor.Lamp housing ambient air produces the temperature difference with indoor temperature, thus cross-ventilation occurs.Cross-ventilation can reduce the temperature of lamp housing, improves the heat-sinking capability of lamp housing.
Outer casing 26 is significantly less than the longitudinal size of lamp housing, the thermal resistance that the object of design is like this to avoid outer casing longitudinal size long and increases lighting apparatus, affects the radiating effect of equipment.Although the space between outer casing 26 and lamp housing 20 can promote the convection current at outer casing two ends, if outer casing is identical with the longitudinal size of lamp housing, just increase the path of air flowing.Long flow path undoubtedly can the flowing velocity of slow down air, reduces the effect of heat radiation.Therefore brief outer casing is best selection, not only makes air with the flowing of the fastest speed but also protect antenna.Outer casing is arranged on the one end near LED light source module 40, and antenna can obtain good insulation protection, and can not be short-circuited with lamp holder.
