Abstract
The utility model relates to an improved structure of an LED photographic lamp, which belongs to the field of lamps for video and photograph. The improved structure comprises an insulating base plate and an LED lamp piece(s) arranged on the insulating base plate, wherein, a Fresnel lens(es) is (are) arranged on the LED lamp piece(s). The number of the LED lamp piece(s) is one or more, and the number of the Fresnel lens(es) is one or more correspondingly. The light emitted through the Fresnel lens(es) is uniform, the light loss is less, the color rendering property is enhanced, and the illumination angle is adjusted as required.
Description
[technical field]
The utility model relates to shooting, photographic eyepiece field, is meant that a kind of is the improvement structure of the flash lamp for photography of light source with LED.
[background technology]
The LED luminous tube is that power consumption is low as the advantage of light source, and photography mostly is mobile operation with shooting, thus must be so that carry and be prerequisite as the artificial light sources of shooting, and need power consumption province, to alleviate the weight of electric energy storage device as far as possible.Therefore, LED is highly suitable for the application in the shooting lighting source field.Shortcoming is that power and illuminance are lower.
LED is few as the product of photography, flash lamp for photography at present, and reason is that illuminance is low, and general using convex lens or concavees lens improve luminous intensity, but bigger spherical aberration and light loss arranged because general convex lens structures is thicker, cause spot center strong, all around a little less than, influence image effect.If adopt high-quality set of lenses then to increase cost and weight.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of improvement structure of LED flash lamp for photography, utilizes Fresnel Lenses to make it reduce light loss, and illumination is even, improves colour rendering, regulates lighting angle.
The utility model is by the following technical solutions:
A kind of improvement structure of LED flash lamp for photography comprises insulated substrate, is arranged on the LED lamp sheet on the insulated substrate, and described LED lamp sheet is provided with Fresnel Lenses.
Described LED lamp sheet is one or more, and the quantity of Fresnel Lenses correspondingly also is one or more.
Also comprise lampshade, described Fresnel Lenses is fixed by lampshade.
Described Fresnel Lenses and described lampshade are split type.
Advantage of the present utility model is:
1. flash lamp for photography light source front end has adopted Fresnel Lenses, utilizes under the condition of identical size and focal length, and Fresnel Lenses is more than the convex lens thin thickness, and light further improves the light output efficiency of light fixture through the little advantage of loss of lens under equal-wattage;
2. utilize the lighting angle of Fresnel Lenses optical principle change LED light emitting diode, collect the light source of LED fully, and evenly throw with the lighting angle demand of reality.Make it reduce light loss, illumination is even, improves colour rendering, regulates lighting angle.
[description of drawings]
In conjunction with the embodiments the utility model being done one with reference to the accompanying drawings describes in detail.
Fig. 1 is the utility model structural representation.
[specific embodiment]
Seeing also shown in Figure 1ly, is the utility model structural representation.A kind of LED flash lamp for photography comprises LED lamp sheet 1, Fresnel Lenses 2, lampshade 3, insulated substrate 4, fixed head 5, protecgulum 6.LED lamp sheet 1 is arranged on the insulated substrate 4, and LED lamp sheet 1 is provided with the lampshade 3 that Fresnel Lenses 2 is housed, and fixed head 5 is used for fixing Fresnel Lenses 2, and outermost is the protecgulum 6 that holder structure and flash lamp for photography fuselage are fixed as one.
LED lamp sheet 1 is two in the present embodiment, and Fresnel Lenses 2 also is two, with lampshade 3 be split type, Fresnel Lenses 2 is installed in the lampshade 3.
LED lamp sheet 1 also can be one or more, and the quantity of Fresnel Lenses 2 correspondingly also is one or more.
Advantage of the present utility model is; Flash lamp for photography light source front end has adopted Fresnel Lenses, utilizes the lighting angle of Fresnel Lenses optical principle change LED light emitting diode, collects the light source of LED fully, and evenly throws with the lighting angle demand of reality.
Single led genus spot light, the lighting angle of general LED crystal is 120 °, the light scattering of sending is more serious, utilizes the optically focused effect of Fresnel Lenses, and convergence of rays in effective scope of application, is played the increase light efficiency, improves the effect of brightness.Fresnel Lenses is with respect to a lamp, fixed focal length, when LED and lens distance not simultaneously, can set the emergent light angle arbitrarily.
The structure that Fresnel Lenses is ultra-thin, the transmitance that makes light is than high many of traditional convex lens, and its weight is less than convex lens.Fresnel Lenses contrasts with passing saturating convex lens, because it adopts concentrically ringed set of lenses, can reduce the sphere influence of lens largely, and emergent light is comparatively soft, and the variable quantity apart from the central point illuminance is little on same light plane.LED lamp sheet for high integration, in small range, concentrated the LED crystal of big quantity, each crystal is different with the distance of lens, it is overlapping to form closely spaced hot spot, use Fresnel Lenses and can obtain comparatively soft lighting effect than the emergent light that uses the saturating convex lens of biography to obtain, make illuminated object obtain the transition of better illumination level, size according to actual light irradiation angle demand and housing, select to make the Fresnel Lenses of different focal and specification, and the distance between definite lens and the LED reaches the light beam that needs purpose.
