Abstract
The utility model discloses a wide angle lighting light-emitting diode (LED) bulb lamp which comprises a lamp head, a radiator connected with the lamp head, a ball bulb connected with the radiator and a plurality of LED light sources covered in the ball bulb. The LED light sources are installed on an end face of the radiator, a light reflection layer is arranged right above the LED light sources, and the light reflection layer is used for reflecting light and transmitting the light. The technical scheme of the wide angle lighting LED bulb lamp adopts a simple structure, expands light radiating a small angle scope to each area of the ball bulb, can have no light dark areas and is good in light uniformity.
Description
Technical field
The utility model relates to the LED lighting field, in particular, relates to the luminous Wide-angle LED bulb lamp of a kind of wide-angle.
Background technology
Along with LED more and more is applied to lighting field, using LED as the bulb lamp of light source the also traditional tungsten filament lighting lamp bubble in replacement progressively.But the characteristic due to LED, its lighting angle is to be confined in certain scope, and therefore, the LED of usining is limited by very large as its application of light fixture of light source, must coordinate other optical component to carry out luminous intensity distribution again, could meet the illumination needs of daily life.As the LED bulb lamp, usually need the angular range irradiated to be the bigger the better, simultaneously, the light uniformity of irradiation is also high better.Therefore, must carry out the design of structure or optics aspect to the LED bulb lamp, enlarge angle and the scope of its irradiation, to meet the needs of people to illumination.
The utility model content
The utility model is for solving the technical problem of above-mentioned existence, a kind of wide-angle luminescence LED bulb lamp is provided, adopts simple structure, the light that only is radiated at small angle range is originally expanded to the regional of ball bubble, and not there will be the light dark space, the light uniformity is better.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of wide-angle luminescence LED bulb lamp, the ball bubble that comprise lamp holder, the radiator be connected with lamp holder, with radiator, is connected, be located at the some LED light sources in the ball bubble, described LED light source is arranged on the radiator end face, directly over described LED light source, position is provided with a reflector layer, and described reflector layer is not only for reflection ray but also for transmitted ray.
Described reflector layer is a semi-transparent semi-reflecting film.
Described reflector layer is one to offer reflective membrane or the semi-transparent semi-reflecting film of some through holes on it.
Described reflector layer is one to offer on it on film of some through holes and paste the semi-transparent semi-reflecting film of one deck.
Described reflector layer has certain thickness, and the through-hole wall on it is for reflection ray.
Described through hole can be various regular shapes or irregularly shaped.
Also be provided with one deck reflector layer on the radiator end face of described installation LED light source.
The beneficial effect that technical solutions of the utility model are brought is as follows:
Wide-angle luminescence LED bulb lamp provided by the utility model, by one deck reflector layer is set above LED light source, and this reflector layer not only can transmitted ray but also can reflection ray, a light part that makes LED light source penetrate is steeped upper area by the reflector layer transmission to ball, a part reflects to ball bubble lower zone by reflector layer, thereby enlarged the range of exposures of light, and scatter out from the ball bubble regardless of the light or the light of reflection that are transmission, can not exist and irradiate phenomenon inhomogeneous and that irradiate dark space.The utility model is simple in structure, and handling ease increases the cost of product hardly.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the profile of Fig. 1;
Fig. 3 is the reflector layer schematic diagram in the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, technical solutions of the utility model are further described in detail; the present embodiment is implemented take technical solutions of the utility model under prerequisite; provided detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
LED bulb lamp disclosed in the utility model shown in Fig. 1, the radiator 2 that comprise lamp holder 1, with lamp holder, is connected, the ball bubble 3 be connected with radiator 2.
Profile shown in Fig. 2, some LED light sources 4 are arranged on the end face of radiator 2, and this LED light source 4 can be directly to be mounted on the radiator end face, can be also to be arranged on the radiator end face by a circuit substrate.In order to be conducive to heat radiation, these some LED light sources 4 evenly are arranged in the peripheral position of radiator 2 end faces.Above LED light source 4, be provided with a reflector layer 5.This reflector layer 5 can either transmitted ray, also can reflection ray.This reflector layer 5 is erected at the top of LED light source 4 by two bracing frames 7.
Shown in Fig. 3, the reflector layer 5 in the present embodiment is semi-transparent semi-reflecting films that one deck offers several through holes 6 on it.A part of light that this semi-transparent semi-reflecting film makes to irradiate is thereon reflexed to ball bubble bottom section downwards, and the transmission of another part light is steeped upper area to ball.For the emergent ray that reaches bulb lamp is more all even soft, on this semi-transparent semi-reflecting film and on the ball bubble all with light-scattering material.Can either transmitted ray in order to reach this reflector layer 5, purpose that also can reflection ray, reflector layer 5 is except adopting said structure and material, it can be also the semi-transparent semi-reflecting film that one deck does not have perforate, or offer the reflective membrane of several through holes on it, or paste the semi-transparent semi-reflecting film of one deck offering on the film of some through holes.And the reflector layer 5 that offers through hole also can have certain thickness, and the hole wall of through hole has also played the effect of reflection ray, thereby make the emergent ray of bulb lamp, not only angle is large, and more even.For reflection also can be taken full advantage of to the light of radiator 2 end faces, on radiator 2 end faces, one deck reflector layer 8 also is set.
Above-described embodiment is interpreted as only being not used in for the utility model is described restriction protection domain of the present utility model.After the content of having read the utility model record, those skilled in the art can make various changes or modifications the utility model, and these equivalences change and modification falls into the utility model claim limited range equally.
