Abstract
The utility model discloses an LED (light-emitting diode) reflector lamp with a heat-radiating structure, which sequentially comprises a front locking ring, a disc-shaped lens, a back locking ring, an aluminum baseplate inlaid with LED lamp beads, and a heat radiator. The front locking ring is provided with round holes which facilitate the convection of air; the heat radiator is integrally in a shape of a hollow circular truncated cone; and the side wall of the heat radiator is provided with heat-radiating ribs. The LED reflector lamp has the characteristics of improving heat-radiating efficiency and lightening the weight of a lamp.
Description
Technical field
The utility model relates to technical field of lamps, refers in particular to a kind of LED shot-light with radiator structure.
Background technology
Use increasing today at led light source, the heat radiation that strengthens led light source is to improve the light efficiency and the main development in life-span.Existing LED shot-light radiator structure mostly is the conductor heat radiation, if the LED lamp power is excessive, then radiator also can increase, thereby gains in weight and cost, influences use experience.
Summary of the invention
At above-mentioned technological deficiency, the technical problem that the utility model need solve provides a kind of raising radiating efficiency, alleviates the LED shot-light of light fixture weight.
The technical problem that the utility model need solve is achieved through the following technical solutions: a kind of LED shot-light with radiator structure, comprise preceding retaining ring, discoid lens, back retaining ring from top to bottom successively, stud with aluminium base and the radiator of LED lamp pearl, retaining ring is provided with convenient cross-ventilated circular hole before described, described radiator integral is the hollow round table shape, and the sidewall of radiator is provided with the radiating ribs rib.
Further: in the LED of above-mentioned radiator structure shot-light, the front end of described radiator is provided with external thread structure, and back retaining ring is provided with the internal thread with radiator external screw thread coupling, and this two part is locked together.The sidewall of retaining ring is provided with external thread structure before described, and back retaining ring is provided with the internal thread that mates with preceding retaining ring external screw thread knot, and with screw-threaded coupling together, fixed lens effectively is so that later maintenance more can improve radiating efficiency.The main purpose of lens is angles of control LED light, by mating different lens, can produce different irradiating angles.
Compared with prior art, in the above-mentioned LED shot-light with radiator structure, described before retaining ring be provided with convenient cross-ventilated circular hole, described radiator integral is the hollow round table shape, the sidewall of radiator is provided with the radiating ribs rib.When LED lamp pearl is worked, the heat of its generation will at first conduct to aluminium base, and aluminium base depends on radiator, and radiator is given in conduction again.Many radiating ribs ribs are arranged on the radiator, and these muscle ribs constitute powerful area of dissipation, can conduct heat in the air fast.But light relies on this heat conducting mode also to be not enough to the powerful thermal source of radiation, at this moment, row's circular hole and radiator on the preceding tight lock ring form cross-ventilation, enter in the circular hole of cold air the past retaining ring, hot-air is discharged from the hollow channel on the heat dissipation conductor, form convection current up and down, thereby the heat on LED lamp pearl, the aluminium base is taken away.By these two kinds of radiating modes, can effectively remove the heat of LED light fixture.
Description of drawings
Accompanying drawing 1 is the overall structure explosive view of the utility model LED shot-light;
Wherein, 1 preceding retaining ring, 2 lens, 3 back retaining rings, 4 LED lamp pearls, 5 aluminium bases, 6 radiators, 11 circular holes, 61 radiating ribs ribs.
The specific embodiment
For the ease of those skilled in the art's understanding, the utility model structural principle is further described in detail below in conjunction with specific embodiment and accompanying drawing.
As accompanying drawing 1, a kind of LED shot-light with radiator structure, retaining ring 1, discoid lens 2, back retaining ring 3, the aluminium base 5 that studs with LED lamp pearl 4 and radiator 6 before comprising successively from top to bottom, retaining ring 1 is provided with convenient cross-ventilated circular hole 11 before described, described radiator 6 integral body are the hollow round table shape, and the sidewall of radiator 6 is provided with radiating ribs rib 61.The front end of described radiator 6 is provided with external thread structure, and back retaining ring is provided with the internal thread with radiator external screw thread coupling.The sidewall of retaining ring 1 is provided with external thread structure before described, and back retaining ring is provided with the internal thread with preceding retaining ring external screw thread knot coupling.
When 4 work of LED lamp pearl, the heat of its generation will at first conduct to aluminium base 5, and aluminium base 5 depends on radiator 6, and radiator 6 is given in conduction again.Many radiating ribs ribs 61 are arranged on the radiator 6, and these muscle ribs 61 constitute powerful area of dissipation, can conduct heat in the air fast.But light relies on this heat conducting mode also to be not enough to the powerful thermal source of radiation, at this moment, row's circular hole 11 on the preceding tight lock ring 1 forms cross-ventilations with radiator 6, enter in the circular hole 11 of cold air the past retaining ring 1, hot-air is discharged from the hollow channel on the heat dissipation conductor, form convection current up and down, thereby the heat on LED lamp pearl 4, the aluminium base 5 is taken away.By these two kinds of radiating modes, can effectively remove the heat of LED light fixture.
The foregoing description only is a preferred implementation of the present utility model; in addition; the utility model can also have other implementations, and under the prerequisite that does not break away from the utility model design, any conspicuous replacement all should fall within the protection domain of the present utility model.
