Description
Technical field
The utility model relates to a kind of LED light fixture, relates in particular to a kind of LED light fixture of multipath heat radiation.
Background technology
LED (light emitting diode) has received much concern since coming out, because it has advantages such as high light efficiency, high-color rendering, long-life, every profession and trade there's no one who doesn't or isn't is devoted to utilize LED, makes the product of oneself more energy-conservation, more environmental protection.In recent years, fast development along with LED science and technology, the luminous efficiency of LED further improves, the price of LED also declines to a great extent, also reach its maturity as the technology of main lighting apparatus with LED, the influence of energy shortage and global warming in addition, LED lamp more energy-conservation than conventional bulb, more environmental protection certainly will become the representative of light source of new generation.
But LED is again a kind of electronic devices and components of high heat generation rate, and too high temperature can reduce the luminous efficiency of LED, shortens the service life of LED, so the LED lamp must have good heat-sinking capability.Existing technical, adopt is fixed to LED on fin or the heat sink more, by simple radiation and conduction heat is taken away, but the efficient of these two kinds of radiating modes is very low, the structural design of fin or heat sink is unreasonable in addition, be difficult to play better heat radiating effect, so LED lamp heat dissipation problem needs to be resolved hurrily.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of LED light fixture with many heat radiation approach is provided, and its radiating effect is superior.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED light fixture of multipath heat radiation, comprise lamp housing, LED lamp, reflector and lampshade, described LED lamp and reflector all are arranged in the described lamp housing, and described LED lamp is arranged on the front of described reflector, described lampshade is connected on the lamp housing, described LED lamp is connected in the lamp housing by support, and described support is the cylindrical stent of hollow, has several through holes on the post jamb of described support.
Further, in order to help heat conduction, described support and described lamp housing integrative-structure.
Further, in order to strengthen radiating effect, the outer wall of described support is provided with radiating fin; Described radiating fin is connected with lamp housing, and radiating fin, support and lamp housing three in one structure.
Further, in order to help the heat conduction, described LED lamp is connected in the top end face of described support, and is provided with the thermal conductive silicon glue-line between LED lamp and support.
Further, in order to help heat conduction, described reflector and described lamp housing clamping, and be provided with the thermal conductive silicon glue-line in the junction of reflector and lamp housing.
Further, a shape, size, position and the corresponding hole of described LED lamp are arranged on the described reflector, described LED lamp stretches out this hole.
Further, described lampshade is the good Ya Like lampshade of translucent effect.
Further, in order to strengthen radiating effect, described reflector is an aluminium sheet.
The beneficial effects of the utility model: (one) support and the die casting of lamp housing integral type are made, help the conduction of heat, the heat that can preferably the LED lamp be sent is taken away, and support is a hollow structure, and have some cross-ventilations hole at Qi Bishang, can heat be exhaled by the mode of convection current, reduce the junction temperature of LED lamp.(2) reflector effectively is connected with lamp housing, can be used as the part of lamp housing radiator, greatly increased the area of dissipation of LED light fixture, and the junction of reflector and lamp housing is coated with the thermal conductive silicon glue-line, the material of reflector is selected the material of other good heat conductivity such as aluminium for use in addition, and radiating effect further strengthens.(3) be coated with the thermal conductive silicon glue-line between described LED lamp and the support, strengthened the validity that connects between the two, radiating effect strengthens once more.(4) effectively prolonged the LED lamp service life, reduced light decay, and the utility model is simple in structure, easily manufactured, cost is low, is fit to large-area applying.
