    A direct-lighting mode and soft-lighting mode interchangeable photography LED illuminating lamp
    TECHNICAL FIELD
    The present invention relates to an illuminating apparatus for photographing or video recording, and more particularly, to a direct-lighting mode and soft-lighting mode interchangeable photography LED illuminating lamp.
    BACKGROUND
    Conventionally used photography LED illuminating lamps may be divided into direct-lighting type and soft-lighting type. The direct-lighting photography LED illuminating lamp is exemplified by “A splicable photography LED illuminating lamp” in Chinese utility model No. 201120502007.5 of the prior application of the present applicant. In this utility model, a plurality of LED lights are provided on a circuit board arranged inside a luminescence window of a lamp casing in a manner of front direct-lighting. The light ray radiation distance of such an LED illuminating lamp may be relatively long but the light rays are relatively glaring. A soft-lighting plate may be added to the luminescence window of the lamp casing to reduce the glaring extent of the light rays. On the other hand, a soft-lighting photography LED illuminating lamp is exemplified by “An LED illuminating lamp for photographing or video recording” in Chinese utility model No. 201320017274.2 which is a prior application by the present applicant. In this utility model, a plastic light guide plate is provided at the inner side of a luminescence window of the lamp casing, which covers the luminescence window with its front face. And, a plurality of LED lights are arranged around the circumferential faces of the plastic light guide plate in a manner of directing lights to the circumferential faces of the plastic light guide plate. The light rays by such an LED illuminating lamp are soft and not glaring but the radiation distance is relatively short or shorter than the light ray radiation distance of the direct-lighting photography LED illuminating lamp.
    The above two types of photography LED illuminating lamps have their own advantages and disadvantages, and usually a direct-lighting photography LED illuminating lamp needs to be used to achieve ideal illumination effects in a photography occasion with a relatively long radiation distance; and a soft-lighting photography LED illuminating lamp needs to be used to achieve ideal illumination effects in a photography occasion with a relatively short radiation distance. If a photographer goes out for photographing or camera photography, he or she has to carry a direct-lighting photography LED illuminating lamp and a soft-lighting photography LED illuminating lamp both, which is inconvenient. Currently, there is no photography LED illuminating lamp which is suitable for relatively long distance photography illumination and relatively short distance photography illumination.
    SUMMARY
    In order to overcome an inconvenience that a camera photographer has to carry a direct-lighting photography LED illuminating lamp and a soft-lighting photography LED illuminating lamp both when going out for photographing or video recording and there is no LED illuminating lamp which is not only suitable for relatively long-distance photography illumination but also suitable for relatively short-distance photography illumination currently, an object of the present invention is to provide an improved direct-lighting mode and soft-lighting mode interchangeable photography LED illuminating lamp so as to overcome the above drawback in the prior art. A technical solution adopted by the present invention in order to solve the above technical problem is as follows. A direct-lighting mode and soft-lighting mode interchangeable photography LED illuminating lamp comprises a lamp casing, a plurality of LED lights installed inside the lamp casing, a power supply connector and a power supply switch provided on the lamp casing, a stand connected to the lamp casing, and a luminescence window provided at the front face of the lamp casing. The lamp casing is provided with a plurality of first LED lights at its front face opposite to the inner side of the luminescence window. The radiation directions of the first LED lights are toward the front of the LED illuminating lamp. The lamp casing is further provided with a plurality of second LED lights at its inner circumferential faces opposite to the inner side of the luminescence window. The lamp casing is provided with a transparent light guide plate for covering the luminescence window and the transparent light guide plate is positioned in front of the first LED lights and opposite to the inner side of the luminescence window. The radiation directions of the second LED lights are toward the outer circumferential faces of the transparent light guide plate respectively. The inward surface of the transparent light guide plate facing the first LED lights is evenly provided with light ray reflection dents. And, the lamp casing is further provided with an illumination mode toggle switch.
    In the above technical solution, the power supply connector may be a dry battery holder or an externally provided power supply outlet.
    In the above technical solution, the stand may be a hot-boot stand for connecting a photography device, a stand for connecting a floor stand or a stand for connecting a table stand.
    In the above technical solution, the lamp casing may be provided with a circuit board therein and the first LED lights and the second LED lights are electrically connected to the power supply connector, the power supply switch, the illumination mode toggle switch, and the circuit board correspondingly.
    In the above technical solution, the luminescence window may be provided on a detachable window frame on the lamp casing.
    In the above technical solution, the lamp casing may be further provided with an illumination brightness regulator and an illumination color temperature regulator. The first LED lights and the second LED lights are electrically connected to the power supply connector, the power supply switch, the illumination mode toggle switch, the illumination brightness regulator and the illumination color temperature regulator and the circuit board correspondingly.
    Beneficial effects of the present invention are as follows: because the lamp casing is provided with a plurality of first LED lights at its front face opposite to the inner side of the luminescence window, the radiation directions of the first LED lights are toward the front of the LED illuminating lamp. The lamp casing is provided with a transparent light guide plate covering the luminescence window and this guide plate is positioned in front of the first LED lights opposite to the inner side of the luminescence window. Thus, the LED illuminating lamp may perform direct lighting through the first LED lights and the transparent light guide plate and provide ideal illumination for long-distance photography. On the other hand, because the lamp casing is provided with a plurality of second LED lights at its inner circumferential faces opposite to the inner side of the luminescence window and the lamp casing is provided with a transparent light guide plate covering the luminescence window, positioned in front of the first LED lights, and opposite to the inner side of the luminescence window, the radiation directions of the second LED lights are toward the outer circumferential faces of the transparent light guide plate respectively.
    Further, the inward surface of the transparent light guide plate facing the first LED lights is provided with light ray reflection dents. Therefore, the LED illuminating lamp may perform soft-lighting illumination through the second LED lights and the transparent light guide plate and thus provide ideal illumination for short-distance photography. Yet, because the lamp casing is provided with an illumination mode toggle switch, the above two illumination mode may realize convenient and rapid interchange on the photographing site. The present invention can not only make the photographer carry few stuff when going out for photographing or video recording and make illumination mode interchanged rapidly and conveniently but also provide a new appliance for the illumination field of photographing or video recording, which supplements the blank of such appliances.
    The present invention will be further described in conjunction with the accompanying drawings and embodiment.
