Description
Technical field
The utility model relates to LED technical field of lamps, relates in particular to a kind of energy-saving radiating type LED Lawn lamp.
Background technology
Lawn lamp develops into the nineties in 20th century, be widely used the one-sided or both sides of road in public places such as city slow lane, narrow track, residential quarter, tourist attraction, park, square, private garden, garden corridors and be used for road lighting, improve the security of people's night trip, be used for increasing the time of people's outdoor activities, improve the safety of lives and properties.On daytime, Lawn lamp can be interspersed townscape; At night, lamp for lawn can provide necessary illumination and life facility, increases Citizens'Sense of Security, can highlight city bright spot again, the beautiful style of deducing, to such an extent as to use till today, developed into ripe industrial chain.Along with popularizing of Lawn lamp, in order to reduce energy consumption, present Lawn lamp has all adopted LED lamp, LED light fixture has luminous efficiency high, the feature that power consumption is little, yet the heat dispersion of LED lamp is most important, the too high meeting of LED light temperature causes light decay, affects luminous and causes LED lamp pearl to reduce service life.
Utility model content
The utility model, in order to solve the aforementioned problems in the prior, provides a kind of perfect heat-dissipating, long service life, the energy-saving radiating type LED Lawn lamp of energy-conservation, good decorating effect.
To achieve these goals, the utility model adopts following technical scheme:
A kind of energy-saving radiating type LED Lawn lamp, comprise base, the lower end of base is provided with feet, the upper end of base is provided with diffuser, the upper end of diffuser is provided with substrate, substrate is provided with some LED lamp pearls, the upper end of described diffuser is provided with heat dissipating housing, the openend of heat dissipating housing is fastened on around diffuser down, the opening part of heat dissipating housing is provided with heat-conducting plate, described heat-conducting plate and heat dissipating housing surround the heat radiation chamber of a sealing, in described heat radiation chamber, be full of inert gas, the bottom in heat radiation chamber is provided with sodium metal, substrate is fixed on the lateral surface of heat-conducting plate, the center of described base is also provided with reflector, the center of substrate and the center of reflector are provided with installation pipe, the bottom center of base is provided with through hole.
Feet on base is arranged in lawn, LED lamp pearl emits beam, after the reflection of reflector, seeing through diffuser shines out, play the decoration function of beautifying the environment night, the heat of LED lamp pearl heat radiation passes to heat-conducting plate by substrate, thereby the sodium metal in the chamber that makes to dispel the heat absorbs heat and melts gradually and form sodium mist, the thermal conductivity of sodium is that tens times of air arrive hundreds of times, when sodium mist rises to the top of heat dissipating housing, contact and realize heat exchange with the bottom surface of heat dissipating housing, heat is absorbed and distributes by heat dissipating housing bottom, sodium mist is out of shape sodium and drips and fall back on heat-conducting plate, meanwhile, sodium on heat-conducting plate constantly forms sodium mist, iterative cycles, thereby high efficiency dissipation of heat is gone out, improve greatly the radiating efficiency of LED lamp pearl, LED lamp pearl long service life.
As preferably, on the medial surface of described heat-conducting plate, be evenly provided with some sphere pits.After sodium metal fusing, flow in metal pit, the heat exchange area between increase and heat-conducting plate, the heat absorption capacity of raising sodium, further promotes the heat radiation of LED lamp pearl.
As preferably, the sphere that the bottom surface of described heat dissipating housing is evagination.Sphere is in order to increase the contact area of heat dissipating housing bottom surface and outside air, strengthens heat exchange.
As preferably, the outside of described heat dissipating housing is arranged with radiating sleeve, is provided with heat radiation gap between radiating sleeve and heat dissipating housing, and the lower end of radiating sleeve is provided with the pore being communicated with the gap of dispelling the heat around, and the upper end of described radiating sleeve is provided with wire netting.Because the upper end temperature of heat dissipating housing is high, environment temperature is low, so just cause the hot-air of radiating sleeve and heat dissipating housing upper end upwards to flow and form negative pressure, Cryogenic air around will enter in heat radiation gap and form circulation from pore, thereby accelerate heat dissipating housing ambient air displacement, take away fast heat dissipating housing heat around; On rainy day, rainwater can be walked heat from heat radiation gap location elution band; Wire netting can prevent that extraneous various foreign material from entering heat radiation and resulting in blockage in gap.
As preferably, described base center is provided with tube connector, and the bottom center of described reflector is provided with adapter sleeve, between described adapter sleeve and tube connector, is threaded.
Therefore, the utlity model has perfect heat-dissipating, long service life, energy-conservation, good decorating effect beneficial effect.
