Abstract
The utility model provides a light-emitting diode (LED) down lamp, which belongs to the field of lighting lamps and is structurally comprises a radiator, an aluminium substrate, a lamp bead, a light reflecting cover, a lamp cover and a driving power supply. The bottom of the light reflecting cover is arranged on the radiator, the aluminium substrate is arranged on the radiator arranged in the light reflecting cover, the lamp bead is arranged on the aluminium substrate and connected with the driving power supply, the lamp cover is arranged at the top of the light reflecting cover, and a decoration cover is further arranged on the outer side of the light reflecting cover. The radiator is arranged at the bottom of the aluminium substrate, heat generated by the lamp bead can be simultaneously sent out through the radiator and the light reflecting cover, the LED down lamp increases radiating area, can send out more heat in unit time, improves radiating efficiency of the LED down lamp, does not radiate with the help of an additional radiator, thereby greatly prolonging service life.
Description
(1) technical field
The utility model relates to a kind of lighting, specifically a kind of LED Down lamp.
(2) background technology
Down lamp is the light fixture that a kind of relative ordinary luminaire has more optically focused property, and one is used for general lighting or floor light.Traditional Down lamp adopts incandescent lamp, Halogen lamp LED or fluorescent lamp etc. as light emitting source usually, and incandescent lamp belongs to thermal light source, and its power consumption is big, brightness is low, the life-span is short, needs the frequent change light source; Though and Halogen lamp LED and fluorescent lamp can be energy-conservation,, be unfavorable for environmental protection because it contains mercury.Having occurred at present with the light emitting diode is the Down lamp of light source, because its characteristics with energy-conservation, low-carbon (LC) and long service life obtain increasing use.
Owing to luminous efficiency and the luminous mass of LED can descend along with the rising of temperature, especially use LED quantity more for a long time, can produce great amount of heat, if untimely losing with the work that has a strong impact on LED.The heat radiation of LED Down lamp at present mainly realizes that through the radiator that adds this radiator volume is big, influences the appearance of LED Down lamp.
(3) summary of the invention
The technical assignment of the utility model is the deficiency to prior art, and a kind of good heat dissipation effect, LED Down lamp elegant in appearance are provided.
The utility model solves the technical scheme that its technical problem adopted:
The LED Down lamp; Comprise radiator, aluminium base, lamp pearl, reflection shield, lampshade and driving power; The bottom of reflection shield is arranged on the radiator; The radiator that is positioned at reflection shield is provided with aluminium base, and the lamp pearl is arranged on the aluminium base and with driving power and is connected, and the top of reflection shield is provided with lampshade.
Above-mentioned LED Down lamp, the outside of its reflection shield also is provided with cover of upholstery.
Above-mentioned LED Down lamp, the quantity of its lamp pearl are 1-5.
The LED Down lamp of the utility model compared with prior art, the beneficial effect that is produced is,
The utility model is provided with radiator in the bottom of aluminium base; The heat that the lamp pearl produces can shed through radiator and reflection shield simultaneously; Increased area of dissipation, the more heat that in the unit interval, can shed has improved the radiating efficiency of LED Down lamp; Need not to dispel the heat, thereby prolonged service life greatly by adding radiator.
(4) description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Among the figure, 1, radiator, 2, aluminium base, 3, the lamp pearl, 4, reflection shield, 5, lampshade, 6, driving power, 7, cover of upholstery.
(5) specific embodiment
Below in conjunction with explanation at length below the LED Down lamp work of 1 pair of the utility model of accompanying drawing.
Shown in accompanying drawing 1; The LED Down lamp of the utility model, its structure comprise radiator 1, aluminium base 2, lamp pearl 3, reflection shield 4, lampshade 5 and driving power 6, and the bottom of reflection shield 4 is arranged on the radiator 1; The radiator 1 that is positioned at reflection shield 4 is provided with aluminium base 2; Lamp pearl 3 is arranged on the aluminium base 2 and with driving power 6 and is connected, and the top of reflection shield 4 is provided with lampshade 5, also is provided with cover of upholstery 7 in the outside of reflection shield 4.
Its processing and fabricating of LED Down lamp of the utility model is simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
Claims (3)
