Abstract
The utility model discloses an LED down light with wider illumination angle, which comprises a heat radiator, a basal plate, a diffusion plate, an LED surface light source and a spring leaf, wherein the spring leaf is arranged on the outer side of the heat radiator, the basal plate and the heat radiator are fixedly connected and in thermal contact, the LED surface light source is fixed on the basal plate, the diffusion plate is arranged within the luminous region of the LED surface light source, and the basal plate and the heat radiator are made of aluminum alloy. With the use of the surface light source as a luminous body and the diffusion effect of the diffusion plate, the illumination of light emitted by the light source is wider and more uniform and soft, so that the LED concealed down light is better in illumination effect.
Description
Technical field
The utility model relates to the LED lighting field, relates in particular to the wider LED Down lamp of a kind of irradiating angle
Background technology
LED be a kind of can be the semiconductor of luminous energy with electric energy conversion, it has changed the luminous principle luminous with the electricity-saving lamp tricolor powder of incandescent lamp tungsten filament, and the employing electroluminescence, the advantages such as it has that volume is little, power consumption is low, long service life, photochromic pure, high brightness, low in calories and environmental protection low-carbon (LC) are the 21 century novel green light sources of generally acknowledging in the world.
LED uses more and more extensive outside Indoor environment, in urban beautification, Landscape Lighting, but the common irradiating angle of existing this LED concealed installation Down lamp is narrow, and the polished bard eye that it sends can not satisfy people and contrast the requirement that tomorrow, benefit improved.
The utility model content
The technical problem that the utility model mainly solves is to provide the wider LED Down lamp of a kind of irradiating angle, can send soft uniform light, satisfies people and contrasts the demand that tomorrow, benefit improved.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: the LED Down lamp that a kind of irradiating angle is wider, it is characterized in that: it comprises radiator, substrate, diffuser plate, LED area source, spring leaf, described radiator outside is provided with spring leaf, described substrate is fixedly connected with and thermo-contact with radiator, described LED area source is fixed on substrate, and described diffuser plate is arranged on the light-emitting zone of LED area source.
Further, described substrate, radiator adopt aluminium alloy to make.
The beneficial effects of the utility model are: the common irradiating angle of LED Down lamp that is different from prior art is narrow, the polished bard eye that it sends and inhomogeneous defective, the utility model adopts area source as illuminator, add the diffusion of diffuser plate, the optic angle degree that light source is sent is wider, more even, softer, thereby make the LED Down lamp that better illuminating effect be arranged, contrast to satisfy people the demand that tomorrow, benefit improved.
Description of drawings
Fig. 1 is the utility model STRUCTURE DECOMPOSITION schematic diagram.
In figure: 1, diffuser plate, 2, substrate, 3, the LED area source, 4, spring leaf, 5, radiator.
The specific embodiment
As scheme as shown in l, the LED Down lamp that a kind of irradiating angle is wider comprises radiator 5, substrate 2, diffuser plate 1, LED area source 3, and described radiator 5 is fixedly connected with two spring leafs 4, and described spring leaf 4 is to be stamped to form by iron plate, is used for installing and fixed L ED Down lamp.Described substrate 2 is fixedly connected with and thermo-contact with radiator 5, described LED area source 3 is fixed on substrate 2, described LED area source 3 and substrate 2 thermo-contacts, described diffuser plate 1 is arranged on the exiting surface of LED area source 3, described substrate 2, radiator 5 are made by aluminium alloy, lightweight, and good heat-transfer.Adopt area source as illuminator, add the diffusion of diffuser plate 1, the optic angle degree that light source is sent is wider, more even, softer, thereby makes LED concealed installation Down lamp that better illuminating effect be arranged.The utility model adopts area source as illuminator, adds the diffusion of diffuser plate 1, and the optic angle degree that light source is sent is wider, more even, softer, thereby makes LED concealed installation Down lamp that better illuminating effect be arranged.
In an embodiment, radiator 5 is circular configuration, and its material is aluminium alloy, is extended with radiating fin on every side, its objective is that increasing radiating surface contacts with air, accelerates heat radiation.
It is to be noted; the utility model is not limited to above-mentioned embodiment; any simple modification, Combination application, equivalent variations and modification that any those skilled in the art do above-described embodiment in based on technical solutions of the utility model all belong in protection domain of the present utility model.
