Abstract
The utility model discloses an air duct type radiating light emitting diode (LED) street lamp. The street lamp comprises a lamp cap and a lamp post, wherein a ventilation dust and a light source cavity are formed in the lamp cap; a high-power LED light emitting module is arranged in the light source cavity; the front surface of the LED module is provided with a reflector and a water-proof glass housing; the back surface of the LED module is fixed at a heat absorbing end of a heat pipe radiator; a radiating end of the heat pipe radiator is arranged in the middle of the ventilation duct; the lamp post is provided with a hollow cavity; the bottom end of the lamp post is provided with an air inlet; the lamp cap is sleeved on the top end of the lamp post; and the ventilation dust in the lamp cap and the cavity in the lamp post form a radiating air duct. In the street lamp, a chimney effect is formed by the ventilation duct consisting of the lamp post and the lamp cap, namely the bottom-up flowing of air is realized by using a hot air ascending principle and pressure difference of a high part and a low part of the lamp post; the heat emitted by the LED is brought away by the flowing of the air; and thus, light attenuation of the LED is reduced, and long life of the LED street lamp is realized.
Description
Technical field
The utility model relates to the LED lighting technical field, particularly a kind of air channel type heat elimination LED street lamp.
Background technology
Present street lamp mainly uses high-pressure mercury lamp and mercury lamp, but the power consumption of sodium vapor lamp and mercury lamp is all bigger, and service life is short, along with LED development of technology in recent years, have advantages such as volume is little, power consumption is low, long service life, brightness height, environmental protection because of it, to become best lighting system undoubtedly, and substitute conventional road lamp, also be the inexorable trend of development.Evolution of heat during led chip work if can not in time heat be come out, will cause the led chip light intensity to reduce, and can quicken light decay simultaneously, have a strong impact on the normal service life of LED.
Summary of the invention
The purpose of this utility model is to provide a kind of air channel type heat elimination LED street lamp, and it can solve prior art and exist the high-powered LED lamp caloric value to be directed at the problem that light decay appears in LED greatly.
The utility model is achieved through the following technical solutions: air channel type heat elimination LED street lamp, comprise lamp holder and lamp stand, be provided with ventilating duct and light-source chamber in the lamp holder, the great power LED illuminating module is installed in the light-source chamber, LED module front is provided with reflection shield and waterproof glass cover, the LED module back side is fixed on the heat absorbing end of heat-pipe radiator, the radiating end of heat-pipe radiator places in the middle of the ventilating duct, the effect of heat-pipe radiator is that the heat that LED sends is transferred to radiating end fast from the heat absorbing end of heat-pipe radiator, radiating end is provided with intensive fin, flows by air heat is taken away.Lamp stand has the cavity of hollow, and the bottom of lamp stand is provided with air admission hole, and lamp sleeve is on the top of lamp stand, and ventilating duct and the cavity in the lamp stand in the lamp holder are formed heat dissipation wind channel.The ventilating duct that the utility model utilizes lamp stand and lamp holder to constitute forms " stack effect ", the different of the high lower pressure differential of hot-air rising principle and lamp stand had both been utilized, realize flowing from bottom to top of air, the heat that the mobile LED of taking away by air sends, thereby reduce the light decay of LED, realize the long-life of LED street lamp.For preventing that foreign matter from falling into the ventilating duct in the lamp holder, be provided with protection network at the place, gas outlet on lamp holder top.
Good effect of the present utility model is: it is with the light emitting source of great power LED as street lamp, have advantages such as volume is little, power consumption is low, long service life, brightness height, environmental protection, and use heat-pipe radiator, the heat dissipation wind channel that utilizes lamp stand and lamp holder to form, form " stack effect ", air is flowed take away the heat that sends when LED works, reduced the light decay of LED effectively, the LED street lamp is really accomplished the long-life.
