Abstract
The utility model belongs to lamps and particularly relates to a high-dissipation LED lamp comprising a circuit substrate. The front of the circuit substrate is provided with an LED chip. The front of the LED chip and the circuit substrate is packaged with a semispherical distribution lens. The back of the circuit substrate is provided with a drive module and a shell. The distribution lens is provided with air holes passing through from front to rear. The rear ends of the air holes are communicated with mounting holes in the circuit substrate. Metal radiating tubes are fixedly mounted in the mounting holes. The front ends of the metal radiating tubes are communicated with the air holes; the rear ends of the metal radiating tubes extend out of the back of the shell from air outlets. The high-dissipation LED lamp has the advantages that air passages which are through from front to rear and which are formed by the air holes and the metal radiating tubes enhance the effect of heat dissipation by air convection; the metal radiating tubes are directly connected with the circuit substrate, heat conduction is faster and more effective, and the heat dissipation capability of the LED lamp is improved on the whole.
Description
Technical field
The utility model belongs to lighting, relates 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 in the utility model 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 utility model 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 the utility model connects before and after forming by passage and heat dissipation metal pipe on the one hand, 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.
