Abstract

The utility model relates to a light-emitting diode (LED) ceiling lamp. The LED ceiling lamp is characterized by comprising an LED light source (1), a radiator (2) is arranged at the back end of the LED light source (1), a horn-shaped reflection cup (3) is arranged at the front end of the LED light source (1), the horn mouth portion of the horn-shaped reflection cup (3) is connected with a face shield (4) which can reflect some of light rays emitted from the LED light source (1) onto the horn-shaped reflection cup (3). The LED ceiling lamp is capable of timely dissipating heat produced by the LED lamp and thereby cooling the LED lamp and prolonging service life of lamps. In addition, the LED light rays are diffused evenly, dark shadows can not happen, and visual perception is good.

Description

A kind of LED lamp affixed to the ceiling

[technical field]

The utility model relates to a kind of LED lamp affixed to the ceiling.

[background technology]

Light emitting diode (LED) is a kind of novel green light source of energy-conserving and environment-protective, with respect to incandescent lamp, the traditional lighting such as fluorescent lamp or high-pressure mercury lamp lamp, but LED saves energy 50～70%, save cable expense 70%, in the world LED has been carried out widely research and extension application work, wherein power is being indicated less than the LED of 1W, extensive use is obtained in the fields such as demonstration and backlight, LED is a photoelectric device, the theoretical life-span can reach 100,000 hour, about 15% electric energy converts luminous energy in the course of work, all the other electric energy are energy transform into heat energy nearly all, for the power that is applied to throw light on for for several watts to hundreds of watts the great power LED, if do not add cooling measure, the led chip junction temperature can rise rapidly, causes the luminance of LED and life-span sharply to be reduced, particularly when junction temperature rose above maximum allowable temperature (being generally 125 ℃), LED can lose efficacy because of overheated.

The traditional endless led light source send light the time, light from the direct projection of LED lamp out can the generating portion shadow in the middle of the missile, the reason that causes this phenomenon is because the light that LED sends does not evenly spread apart, thereby can produce shadow, light is not attractive in appearance, gives people's visual experience bad.

[utility model content]

Technical problem to be solved in the utility model is for above-mentioned deficiency of the prior art, provide a kind of dissipation of heat that can in time the LED lamp be produced to go out, thereby realize the LED lamp is lowered the temperature, prolong light fixture service life, the LED lamp wiring evenly diffuses out, can not produce shadow, the LED lamp affixed to the ceiling that visual experience is good.

For achieving the above object, the utility model has adopted following technical proposals:

A kind of LED lamp affixed to the ceiling, comprise led light source, be provided with radiator in described led light source rear end, be provided with trumpet-shaped reflector at described led light source front end, be connected with the face shield that the light portion that described led light source penetrates can be reflexed on the described reflector at described reflector horn mouth place.

Radiator comprises heat carrier, thermal conductor, radiator as mentioned above, described thermal conductor is " I " type, described radiator is " V " font, and described thermal conductor and described radiator form " Y " type, and arranges along described heat carrier external circumferential array outward opening.

Face shield adopts the PMMA material to make as mentioned above.

Face shield adopts the PC material to make as mentioned above.

Face shield adopts glass material to make as mentioned above.

In as mentioned above led light source, radiator, reflector arranged outside lamp housing is arranged, described face shield links to each other with described lamp housing.

Be provided with louvre at lamp housing as mentioned above.

Lamp housing employing thickness is the aluminium flake punch forming of 1mm as mentioned above.

The beneficial effects of the utility model are:

1, be provided with radiator in the led light source rear end among the utility model, the dissipation of heat that can be in time the LED lamp be produced be gone out, thereby realizes the LED lamp is lowered the temperature, and prolongs light fixture service life.

2, be provided with reflector on the led light source top among the utility model, reflector can not produce shadow so that the LED lamp wiring evenly diffuses out, and visual experience is good.

3, face shield adopts the PMMA material of high transmission rate to make among the utility model, its light transmittance reaches more than 92%, polymethyl methacrylate abbreviation code name is PMMA, the translucent plastics of a kind of milky, that to synthesize up to now in the transparent material quality the most excellent, the kind that price relatively suits again, the PMMA resin is the material of asepsis environment-protecting.

[specific embodiment]

Below in conjunction with accompanying drawing the utility model is done further detailed description.

As shown in Figure 1, a kind of LED lamp affixed to the ceiling, comprise led light source 1, be provided with radiator 2 in described led light source 1 rear end, be provided with trumpet-shaped reflector 3 at described led light source 1 front end, be connected with the face shield 4 that the light portion that described led light source 1 penetrates can be reflexed on the described reflector 3 at described reflector 3 horn mouth places, the radiator of led light source rear end, the dissipation of heat that its role is to can be in time the LED lamp be produced be gone out, thereby realizes the LED lamp is lowered the temperature, and prolongs light fixture service life, the reflector on led light source top, its role is to can not produce shadow so that the LED lamp wiring evenly diffuses out, visual experience is good.

As shown in Figure 3, described radiator 2 comprises heat carrier 21, thermal conductor 22, radiator 23, described thermal conductor 22 is " I " type, described radiator 23 is " V " font, and described thermal conductor 22 forms " Y " type with described radiator 23, and arranges along described heat carrier 21 external circumferential array outward openings, be provided with the mounting screw hole at this radiator heat carrier position, link to each other with led light source by the M3 screw, it is fast to conduct heat, and radiating efficiency is high.

In the present embodiment, described face shield 4 adopts the PMMA material to make, its light transmittance reaches more than 92%, polymethyl methacrylate abbreviation code name is PMMA, is the translucent plastics of a kind of milky, is that to synthesize up to now in the transparent material quality the most excellent, the kind that price relatively suits again, the PMMA resin is the material of asepsis environment-protecting, and as another kind of embodiment of the present utility model, face shield 4 can also be made by PC material or glass material.
