Yet,, therefore adopt LED often to have problems such as the irradiation space is less, light is dazzling as the illuminating lamp of light source because the light beam that LED distributes is comparatively concentrated.For addressing the above problem, people directly use the sheen lampshade at the led light source place usually.Yet after using the sheen lampshade, will inevitably reduce the light efficiency of LED, reduce the brightness of illuminating lamp.
The utility model content
Technical problem to be solved in the utility model is, at the above-mentioned LED illuminating lamp irradiation problem that the space is less, light is dazzling, provides a kind of new LED illuminating lamp.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED illuminating lamp is provided, comprise heat radiation rack and be connected in LED illuminator on the described heat radiation rack, the reflective surface that also comprises the range of exposures that is positioned at described LED illuminator, described reflective surface are provided with a plurality of reflective salient points and/or concave point.
In LED illuminating lamp described in the utility model, two heat-conducting plates that described heat radiation rack comprises heat sink, is positioned at the radiating fin of described heat sink upper surface and is positioned at the two ends of described heat sink lower surface, the back side of described reflective surface is attached at the lower surface of described heat sink.
In LED illuminating lamp described in the utility model, the front of described reflective surface is concave surface, convex surface or plane.
In LED illuminating lamp described in the utility model, described LED illuminator comprises substrate and is located at the LED of substrate front side that the back side of described substrate is attached at the inboard of heat-conducting plate.
In LED illuminating lamp described in the utility model, the angle of the inboard of described heat-conducting plate and heat sink lower surface is less than or equal to 90 degree.
In LED illuminating lamp described in the utility model, also comprise two tube stands that are sheathed on described heat radiation rack two ends respectively, each described tube stand is provided with lamp base and electron rectifier, and the output of described electron rectifier is connected to the LED illuminator.
In LED illuminating lamp described in the utility model, the LED illuminator of each end of heat radiation rack and heat-conducting plate cover in the tube stand.
In LED illuminating lamp described in the utility model, each described tube stand is provided with a plurality of air-vents.
In LED illuminating lamp described in the utility model, the inboard of each described tube stand is provided with reflector layer.
In LED illuminating lamp described in the utility model, also comprise Transparent lamp shade, described Transparent lamp shade and tube stand wrap up reflective surface and LED illuminator together.
Implement LED illuminating lamp of the present utility model and have following beneficial effect: the reflective surface by surface band salient point and/or concave point carries out diffuse reflection with the irradiates light of LED illuminator, thereby increased the range of exposures of whole LED illuminating lamp, avoided the light part strong excessively simultaneously.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of LED illuminating lamp embodiment of the present utility model;
Fig. 2 is the internal structure schematic diagram of LED illuminating lamp among Fig. 1.
The specific embodiment
The light that the utility model produces the LED illuminator throws light on have the reflective surface diffuse reflection of salient point/concave point by a surface after, thereby makes the range of exposures of illuminating lamp increase, and has avoided the light part strong excessively.
As shown in Figure 1, 2, LED illuminating lamp in the present embodiment comprises heat radiation rack, is connected in LED illuminator 14 and reflective surface 18 on this heat radiation rack.Wherein reflective surface 18 is positioned at the range of exposures of LED illuminator 14, and this reflective surface 18 is provided with a plurality of reflective salient points and/or concave point.When the light that produces when LED illuminator 14 energising backs shines reflective surface 18, because the existence of reflective salient point and/or concave point makes light produce diffuse reflection, and the non-specular surface reflection, thereby the scope of whole LED illuminating lamp irradiation increases greatly, and avoids producing dazzling light.
Two heat-conducting plates 13 that heat radiation rack in the foregoing description comprises heat sink 11, is positioned at the radiating fin 12 of heat sink 11 upper surfaces and is positioned at the two ends of heat sink lower surface.Reflective surface 18 can be the reflector that the front is provided with reflective salient point and/or concave point, and the back side of this reflector directly is attached at the lower surface of heat sink 11; This reflective surface 18 also can be realized by other modes in addition, for example is located at the reflecting coating of heat sink 11 lower surfaces.Like this, reflective surface 18 is because the heat that the light irradiation produces also can be by heat sink 11 and radiating fin 12 releases.
According to different needs, above-mentioned reflective surface 18 can be concave surface, convex surface or plane.For example when the bigger range of exposures of needs, reflective surface 18 adopts convex surfaces; When the stronger brightness of needs, reflective surface 18 adopts concave surfaces.
For improving luminous efficiency, the angle of the inboard of heat-conducting plate 13 and heat sink lower surface is less than 90 degree.Thereby the light that LED energising produces can be more shine on the reflective surface 18.
Similar with existing illuminating lamp, be arranged with two tube stands 15 respectively at the two ends of heat radiation rack, each tube stand 15 is provided with lamp base 16 and electron rectifier 19, and wherein the output of electron rectifier 19 is connected to the LED illuminator.In the present embodiment, the LED illuminator 14 of each end of heat radiation rack and heat-conducting plate 13 cover in the tube stand 15, thereby the local light that the light direct irradiation of avoiding LED illuminator 14 to produce causes is strong excessively.
For ease of the end heat radiation, on each tube stand 15, a plurality of air-vents 17 can be set.
Be to strengthen illumination efficiency, the inboard of each tube stand can be provided with reflector layer (can be minute surface), thereby the light that LED illuminator 14 shines this reflector layer is reflexed to reflective surface 18.
Similar with existing illuminating lamp, for avoiding dust accretions, Transparent lamp shade can be set to illuminating lamp inside (for example LED illuminator etc. is located), this Transparent lamp shade 20 and tube stand 15 wrap up reflective surface 18 and LED illuminator 14 together.
Certainly, in actual applications, the LED illuminating lamp is not limited to the structure in the foregoing description, and for example the LED illuminator can only be one, and the position of LED illuminator and reflective surface also can change etc.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
