Description

A kind of LED outdoor lighting lamp

Technical field:

The utility model relates to a kind of LED outdoor lighting lamp, refers specifically to and a kind ofly can intercept the importing of extraneous irradiation heat, effectively derives internal heat and the directive LED outdoor lighting lamp that converges the hot spot of clear, even, adjustable size.

Background technology:

The LED outdoor lighting lamp of present stage adopts the incorporate design of shell and radiator usually in order to dispel the heat and to seek shelter from wind and rain, and helps the two-way conduction of heat like this.This is the method for the basic design of industry inner structure design engineer, under the situation that does not increase the mechanical processing technique difficulty, incorporate design is carried out in the heat insulation and heat radiation of shell, can satisfy again and forfend dust storm, airborne dust, sleet, help improving the performance of the heat radiation of LED light fixture, heat insulation, rain and snow, dirt sand, thereby increase the reliability of LED outdoor lamp.The LED outdoor lamp of present stage is when ambient temperature is low, and the temperature of lamp interior can be beneficial to heat radiation by shell to exterior conductive.But, when ambient temperature was higher than temperature inside, reverse had just appearred in situation, and extraneous temperature will import to inside, keep along with the temperature in the external world is lasting, inner temperature rise will build up, and certainly will will reach inside and outside temperature balance, and this just influences the job security and the reliability of inner LED and electronic component, reduce working life and serviceability, What is more is exactly to cause LED to produce the light decay phenomenon in advance, reduces luminous intensity, the effect of influence illumination.

The utility model content:

In order to solve the problem that exists in the above technical field, the utility model proposes following technical solution.

The utility model is by metal shell, thermal insulation layer, the internal reflection layer, ventilation shutter, the LED radiator, optics is the light device all, snoot, Metal halogen lamp, the hernia flash lamp, led array, optics aggregator assembly, driving power and controller are formed, in the inside of metal shell optics aggregator assembly is installed from left to right, snoot, the LED radiator, optics aggregator assembly is buckled the inboard that is screwed at metal shell by spiral shell, optics aggregator assembly is twisted mutually by screw with snoot and is closed, snoot be installed in the LED radiator above, there is the LED wiring board on the left side of being close to the LED radiator, on LED wiring board plate face, led array is installed, the uniform Metal halogen lamp that is equipped with around led array, at the middle part of led array the hernia flash lamp is installed, inboard at snoot, near LED wiring board one end all light devices of optics are installed, the shutter of heat transmission is installed with trailing flank on the base plate of metal shell, in order to prevent that the heat that external hot irradiation produces from importing LED lighting inside, thermal insulation layer is installed on metal shell, in order to prevent not imported the LED lighting by the heat that thermal insulation layer intercepted, the internal reflection layer is installed below thermal insulation layer, the heat that imports LED lighting inside on a small quantity outwards can be reflected away.Above the outside of snoot, driving power is installed, gets the power of electric back reduced-voltage starting as led array; Below the outside of snoot, controller is installed, be used for switching controls to led array and various duties.

The theoretical work time of LED can reach nearly 100,000 hours, but because the restriction of the various reasons on using does not far reach desirable state its actual life.The heat dissipation technology of LED is one of three big key technologies that influence in the LED lighting engineering service life.Structure of the present invention designs at such application, and it can be isolated under the natural environment effectively because the heat that irradiation produces.When ambient temperature raises, the thermal source that on LED lamp outer casing surface, produces, will be blocked in outside the metal shell surface, no longer entered within the LED lighting by conduction, this a part of thermal source has just been isolated, sheathing material is selected the metal material of low heat capacity for use, helps heat radiation with heat insulation.It two is exactly the structure heat dissipation design of LED lamp interior, " heat dissipation technology of 201010229507.6 patents; as a kind of mode of its heat radiation; secondly in the structure design system of inside; utilized the heat radiation theory of convection current and conduction has made up a local miniclimate heat dissipation environment that thermal convection current circulates in the LED lamp interior to the employing of LED radiator portion.The temperature air-flow that LED light fixture bottom is lower, the vertical ventilation fin flow guiding groove that makes up along radiator upwards conducts, having arrived this a part of thermal current expansion of top quickens, ventilation shutter that just be provided with along the enclosure interior structure naturally, outwards heat radiation is to the atmospheric environment discharges heat of nature, and this has just constituted the circulation canal of a heat radiation.The characteristics of this heat radiation patented technology are: the heat that the heat of atmospheric exterior irradiation produces on case surface, can not enter the LED lamp interior, and this a part of heat is not participated in inner thermal balance exchange and accumulation.LED is at luminous produced simultaneously heat, owing to adopted the patented technology method of LED heat radiation, its caloric value is all conducted on the surface of radiator.Third part is exactly the radiator structure of indoor design, the temperature of LED spreader surface by convection current vertical ventilation fin flow guiding tank circuit structure, thermal current quickens the up inner heat exchange circulation the top that converges in, the thermal current that is gathered in this expands and disperses, and the shutter by the structure setting distributes to space outerpace.Speeding up of the thermal cycle that such structure makes, rate of heat exchange improves, force the temperature rise of LED tube core to remain within the desirable temperature limit conversely again, even omit under the environmental condition in the evil of strong wind and heavy rain, the heat insulation design of keeping out the wind of back shutter one side, guarantee and inner ventilation and heat, look after the result of use of keeping out the wind and taking shelter from rain again, the basic guarantee of a safe and reliable job is provided on physical environment, make the security reliability of LED luminescent device be improved, the LED device has been demonstrated fully the energy-conserving and environment-protective of LED outdoor lamp owing to the light decay phenomenon that temperature rise occurs delays, efficient illumination, the characteristics of long service life.

The beneficial effects of the utility model are exactly the work that guarantees that the LED light fixture out of doors can be safe and reliable under the adverse circumstances, satisfy of the harsh requirement of LED luminescent device to radiating condition, allow the heat of light fixture external environment condition irradiation intercept beyond the surface of light fixture, do not interfere the stack and the accumulation of lamp interior heat; The cavity that the LED lamp interior makes up makes full use of the principle of hot conduction, convection current, radiation, the heat that will produce in the time of will working by the LED of fitting structure inside, the waste heat that the LED driving power produces etc., under the microclimate conditions that the structure member of inside is constructed, fully effectively it is exported to the outside atmosphere space.The heat interaction of rational and orderly circulation just makes the heat that the LED luminescent device, driving power device etc. of LED lamp interior produce like this, not in inside stack and accumulation, thereby reach and satisfy of the requirement of LED device fully for thermal environment, when guaranteeing that it is efficient luminous, do not cause the LED luminescent device to enter the light decay phase in advance, realize LED long-life work requirements truly.
