Preferably, in the above-mentioned LED Down lamp, the bottom of described ceramic lamp body is set to the flaring limit.
Preferably, in the above-mentioned LED Down lamp, described LED lamp group is encapsulated on the described ceramic lamp body.
Preferably, in the above-mentioned LED Down lamp, also comprise the light-passing board that is arranged in the described ceramic lamp body, described light-passing board and described ceramic lamp body surround placed cavity, and described LED lamp group is positioned at described placed cavity.
Preferably, in the above-mentioned LED Down lamp, described ceramic lamp body is cylindrical lamp body.
Preferably, in the above-mentioned LED Down lamp, described LED lamp group comprises a plurality of LED lamps that circumferentially are evenly arranged along cylindrical lamp body.
Can find out from above-mentioned technical scheme, the lamp body that the LED Down lamp that the utility model provides uses is ceramic lamp body, because ceramic material has good insulating, thermal conductivity is high, infrared emittance is large, the coefficient of expansion is low characteristics, therefore use ceramic lamp body can either guarantee preferably thermal diffusivity, have again good insulating properties, so under the condition of, high humidity high in temperature, ceramic lamp body stable performance, can reduce lamp body generation electric leakage accident, improve the safety in utilization of LED Down lamp.
In addition, oxidation can not occur in the ceramic lamp body in the LED Down lamp that the utility model provides, and has prolonged service life.
Simultaneously, because ceramic lamp body has sufficiently high mechanical strength, can either carry components and parts, can also use as support member, as supporting the member of LED lamp group or other power supply usefulness; Therefore can reduce the use of accessory in the LED Down lamp, it is simplified the structure.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the LED Down lamp that provides of the utility model embodiment.
The specific embodiment
The utility model embodiment provides a kind of LED Down lamp, has realized improving the safety in utilization of LED Down lamp when guaranteeing radiating effect.
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to accompanying drawing 1, the LED Down lamp that the utility model embodiment provides comprises ceramic lamp body 1 and the LED lamp group 2 that is arranged in the ceramic lamp body 1.
The lamp body that the LED Down lamp that the utility model embodiment provides uses is ceramic lamp body 1, because ceramic material has good insulating, thermal conductivity is high, infrared emittance is large, the coefficient of expansion is low characteristics, therefore ceramic lamp body 1 can either guarantee preferably thermal diffusivity, has again good insulating properties, so under the condition of, high humidity high in temperature, 1 stable performance of pottery lamp body can reduce lamp body generation electric leakage accident, has improved the safety in utilization of LED Down lamp.
In addition, oxidation can not occur in the ceramic lamp body 1 in the LED Down lamp that the utility model embodiment provides, and has prolonged service life.
Simultaneously, because ceramic lamp body 1 has sufficiently high mechanical strength, can either carry components and parts, can also use as support member, as supporting the member of LED lamp group 2 or other power supply usefulness; Can reduce the use of accessory in the LED Down lamp, it is simplified the structure.
Preferably, in the LED Down lamp that above-described embodiment provides, ceramic lamp body 1 is the integral type structure.Pottery lamp body 1 is adding man-hour, one-shot forming, like this since, ceramic lamp body 1 each several part connects tight, does not connect the slit, can guarantee very high mechanical strength, has avoided being damaged in the junction, has improved the service life of LED Down lamp.In addition, the ceramic lamp body 1 that the utility model embodiment provides also can be split-type structural, carries out bonding by adhesive to each several part again.
In order to increase the irradiated area that makes the LED Down lamp, in the LED Down lamp that above-described embodiment provides, the bottom of ceramic lamp body 1 is set to flaring limit 11.The bottom of pottery lamp body 1 is set to flaring limit 11, even it is horn-like that the bottom of ceramic lamp body 1 is made as, and then make the light source outlet of LED lamp group 2 be the flaring mouth, make light 11 ejaculations along the flaring limit, enlarge light and be mapped to irradiated area indoor or that other devices are interior, so that indoor light is even, reduced the exposure intensity of light, reduce the stimulation of light intensity to eyes, increased comfort.
Need to prove, the bottom of ceramic lamp body 1 is the end that light source penetrates, and its other end is the top.
