Abstract
The invention belongs to lighting lamps and relates to an LED lamp high in heat dissipation capability. The LED lamp high in heat dissipation capability comprises a circuit substrate provided with an LED chip on the front side. The LED chip and the front side of the circuit substrate are packaged through a hemispherical light distribution lens. A drive module and a shell are installed on the back side of the circuit substrate. The light distribution lens is provided with vent holes, each of which is through front and back. The rear ends of the vent holes are communicated with corresponding mounting holes in the circuit substrate. Metal heat dissipation tubes are fixedly installed in the mounting holes. The front ends of the metal heat dissipation tubes are communicated with the vent holes, and air outlets in the back ends of the metal heat dissipation tubes stretch out of the back side of the shell. According to the LED lamp high in heat dissipation capability, on the one hand, because airflow passages, each of which is through front and back, are formed by the vent holes and the metal heat dissipation tubes, the effect of heat dissipation through convection is enhanced; on the other hand, because the metal heat dissipation tubes are directly connected with the circuit substrate, heat dissipation through conduction is faster and more effective, and accordingly the heat dissipation capability of the LED lamp is improved on the whole.
Description
Technical field
The invention belongs to lighting, relate to a kind of high heat-sinking capability LED light fixture.
Background technology
As the high-power LED lamp of lighting source, its heat radiation is the outstanding problem that need to first solve.For front, adopt especially the LED light fixture of lens packages, its heat radiation is more difficult.Conventionally the heat dissipating method adopting is, at the circuit substrate back side of LED chip, the radiator with radiating fin is installed, dissipation of heat LED being produced by radiator is gone out, because radiator is positioned at the LED chip opposition side on circuit substrate, the caloric requirement that LED produces is through circuit substrate, heat radiation glue-line, heat sink.Owing to being subject to the impact of heat conductivility and the heat-conducting area of material in heat transfer process, it is desirable that radiating effect can not reach.
Summary of the invention
Technical problem to be solved by this invention is, provides that a kind of heat-sinking capability is strong, the high heat-sinking capability LED light fixture of good operating stability.
High heat-sinking capability LED light fixture of the present invention includes the circuit substrate that a front has LED chip, and the front of LED chip and circuit substrate is encapsulated by hemispheric light-distribution lens, and the back side of circuit substrate is provided with driver module and housing; The passage connecting before and after having on described light-distribution lens, passage rear end communicates with the installing hole on circuit substrate, is installed with heat dissipation metal pipe in installing hole; Heat dissipation metal pipe front end communicates with passage, and stretch out from back side of shell gas outlet, rear end.
Described passage is distributed with a plurality of on light-distribution lens along even circumferential.
The heat dissipation metal pipe of installing in described each installing hole is many bundle structure.
Described heat dissipation metal pipe back segment opens and is radial to circumferential outer edge bending.
The gas channel that one aspect of the present invention connects before and after forming by passage and heat dissipation metal pipe, strengthened gaseous exchange radiating effect, by heat dissipation metal pipe, be directly connected with circuit substrate on the other hand, make heat loss through conduction more fast, effectively, thereby in integral body, be the heat-sinking capability that has improved LED light fixture.
