Background technique

Currently used LED lighting lamps for shooting, the structure can be divided into two types: direct illumination and soft light. Among them, the LED illumination for direct illumination is as follows: A splicable LED type illumination lamp for imaging" is a circuit board in which a plurality of LED light sources are arranged in a direct illumination manner and arranged in a light-emitting window of a lamp housing. The LED type illumination lamp can be illuminated at a relatively long distance, but the light is relatively glaring. The "lighting type LED lighting lamp" of the Chinese Patent No. 201320017274.2, which is the first application of the present invention, is mounted on the inner side of the light-emitting window of the lamp housing. The front side of the plastic light guide plate is covered with a plastic light guide plate, and a plurality of LED light sources are arranged on the outer side of the side of the plastic light guide plate in a direct manner to the side of the plastic light guide plate. The LED type illumination lamp has a soft light and is not glare, but the illumination distance is relatively short, and the illumination distance of the LED type illumination lamp for direct illumination type is shorter.

The above-mentioned two types of LED-type illumination lamps for shooting have their own advantages. In the shooting situations where the illumination distance is long, it is often necessary to use the LED illumination lamps for direct-illumination to achieve the desired illumination effect; the shooting distance is relatively close (especially In the case of characters, it is often necessary to use LED lighting with soft light to achieve the desired lighting effect. If the photographer needs to carry the direct-illumination LED lighting and the soft-lighting LED lighting when shooting out or taking pictures, it is very troublesome.

To this end, the applicant has previously applied for a direct-illumination and soft-light convertible LED illumination lamp of the Chinese Patent Application No. 201610007562.8, so that the photographer can carry only one illumination light when photographing or photographing. It can be used as a direct-illumination type LED illumination lamp or as a soft-light type LED illumination lamp. The structure comprises a lamp housing, a plurality of LED light sources installed in the lamp housing, a power connector and a power switch disposed on the lamp housing, and a connection bracket disposed outside the lamp housing, wherein the front surface of the lamp housing is provided with a light-emitting window a front LED light source is arranged on the front side of the light-emitting window, and a front LED light source is directed toward the front of the LED illumination lamp, and a plurality of side LEDs are arranged on the lamp housing on the inner side of the illumination window. a light source, a transparent light guide plate covering the light emitting window is mounted on the lamp housing in front of the front LED light source inside the light emitting window, The illumination directions of the side LED light sources are respectively directed to the side surfaces of the transparent light guide plate, and the transparent light guide plate is uniformly covered with light reflection pits on the inward surface of the front LED light source, and the illumination is converted on the lamp housing. switch. However, the disadvantage of this solution is that since the transparent light guide plate is blocked in front of the front LED light source, the direct illumination brightness of the front LED light source is lost, and the direct illumination brightness cannot be fully utilized; Since the back surface of the transparent light guide plate must have high transparency, the arrangement of the light reflecting pits on the transparent light guide plate is limited, and thus the light intensity of the side LED light source is reduced to the front, and the soft light cannot be fully utilized. Light intensity.
