Description
Technical field
The utility model relates to lighting, and especially a kind of is the lantern of light source with the light emitting diode.
Background technology
Light emitting diode is as a kind of energy saving illuminator, and in general, its application is presented in each end product through numerous light emitting diode combined.Along with the continuous maturation of its application technology more and more receives an acclaim, application constantly enlarges, and product is more and more abundanter.With lighting field, the light fixture kind made from light emitting diode is a lot, like fluorescent lamp, bulb lamp, street lamp, bulkhead lamp capable, lantern or the like.
The LED lantern is a kind of multiduty lighting, and its structure is varied, comprises a plurality of light emitting diodes, reflector, lampshade and handle.In general, the reflector of LED lantern is plate.Chinese patent discloses a kind of Portable lamp (publication number 201487584.U), and numerous light emitting diodes are installed on the reflector, in the upper end and the lower end of reflector reflector is set respectively.No matter be the LED lantern of plate reflector, the LED lantern of reflector still is set respectively at the two ends up and down of numerous light emitting diode reflectors, low to the utilization rate of luminous energy; Cause brightness low; Irradiation distance is short, even the user does not in use see the road surface, the unsafe factor increase.
Summary of the invention
The utility model is intended to overcome the above-mentioned deficiency of prior art, and a kind of lantern is provided.It is light source with the light emitting diode, and high to the utilization rate of luminous energy, brightness is high, and irradiation distance is far away.
For this reason, the technical scheme of a kind of lantern of the utility model is following:
The utility model lantern; Comprise reflector and a plurality of light emitting diode; Said light emitting diode is connected with its drive circuit, a plurality of said light emitting diodes of array on the reflector, and said reflector comprises a plurality of refractive bodies of array unit; Said reflecting unit body is corresponding one by one equipped with said light emitting diode; Said reflecting unit body is the reflective pit of the conical pit shape that is combined to form of reflective surface, and the osculum end of said reflective pit and big opening end lay respectively at leaning on the side in the lamp and leaning on the outer side of lamp of reflector, and said light emitting diode is arranged at the osculum end of said reflective pit.
Technique scheme is further set forth:
The reflective surface of said reflecting unit body comprises four bodies and measure-alike trapezoidal reflective surface, and four said trapezoidal reflective surfaces are combined to form the reflective pit of conical pit shape, and the cross section vertical with the depth direction of said reflective pit is square.
The angle of two said relatively trapezoidal reflective surfaces is 60 degree.
Said trapezoidal reflective surface is coated with the aluminium film.
Said reflector is packed on the lamp body.
Transparent lampshade is installed on lamp body, and said lampshade faces toward the light direction of light with said reflector and said light emitting diode cover cap.
On lamp body, be shaped on handle.
Compare with prior art, the beneficial effect of the utility model is:
One of which, the utilization rate of luminous energy is high.The reflector of the lantern of prior art is plate, or only at the two ends up and down of numerous light emitting diode reflectors reflector is set respectively, and bright dipping disperses.Because the light emitting diode that is applied to lantern is under lens and secondary lens effect; The angle of divergence of its light is about 120 degree; The reflection of reflecting that be provided with respectively by the two ends up and down of plate reflector or reflector; Quite a few light is scattered in outside the effective target, and the brightness of effective target is reduced.Each light emitting diode of the utility model is equipped with a refractive body unit; And each refractive body unit is the reflective pit of conical pit shape, reflective pit have be oppositely arranged four trapezoidal surface of emissions, and the angle of two said relatively trapezoidal reflective surfaces be with 60 the degree; Said light emitting diode is arranged at the osculum end of said reflective pit; The light of said like this light emitting diode concentrates on interior ejaculation of scope of 60 degree angles, in the projection range set, the brightness of target place is improved; Simultaneously, each spot light is integrated in numerous light emitting diodes and corresponding refractive body unit thereof, forms a kind of effect of area source, causes the integral illumination effect that comprises brightness to improve.Its two, reflective surface is coated with the aluminium film, has strengthened reflecting effect.Its three because brightness improves, the irradiation distance lengthening sees clearly target, is beneficial to work or walking, avoids operating irregularity and security incident.Its four, be convenient to make, be convenient to implement, have the reflector of reflective pit through molding production, vacuum aluminum-coated getting final product carried out on the surface of each pit.Its five, the lantern purposes of the utility model is wide, like outdoor walking illumination, tourism illumination, room lighting, mine lighting and other operating illumination etc.
