External OLED type illuminating lamp for camera or video camera

Abstract

Disclosed is an external OLED type illuminating lamp for a camera or a video camera. The external OLED type illuminating lamp overcomes the defects that components like a dodging cover and a soft light cover need to be additionally arranged to improve the uniformity and the softness of illumination in an existing external LED type illuminating lamp for the camera or the video camera, a special radiator needs to be arranged in a high-power light source, the size is large, the weight is high and carrying is inconvenient. According to the technical scheme, the external OLED type illuminating lamp comprises a lamp housing, an electric light source, a circuit board, a battery and a connector for being matched with the camera or the video camera, and the electric light source, the circuit board, the battery and the connector are arranged on the lamp housing. The external OLED type illuminating lamp for the camera or the video camera is characterized in that the electric light source is an OLED light source which is installed and fixed on a front port of the lamp housing, the thickness of the light source is smaller than or equal to 2mm, the length of the light source is 50-450mm, the width of the light source is 40-450mm, the color temperature of the light source is 3,000-7,000K, and the battery is in power supply connection with the OLED light source through the circuit board.

Description

technical field [0001] The invention relates to an illuminating device for photographing or video recording, in particular to an OLED type illuminating lamp for external connection or cooperation with photographing or video recording equipment. Background technique [0002] Organic Light Emitting Diode (OLED) is a new type of semiconductor light source developed in recent years, which is formed by coating or plating an electroluminescent layer on a substrate. Compared with the previous semiconductor light source LED, it has the characteristics of uniform and soft light emission, little heat generation, more power saving, ultra-thin, light weight, fast response, easy installation, simple manufacturing process, and low cost. However, OLED is mainly used in the field of flat panel display at present, and it is not yet mature and extensive in the field of lighting. [0003] Chinese Patent No. 201220149552.5 discloses a built-in mobile phone OLED ring flashlight, which is a ring...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the existence of the existing external LED lighting for cameras or video cameras, it is necessary to add components such as uniform light cover and soft light cover to improve the uniformity and softness of the light. The high-power LED light source needs to be equipped with a special radiator. Larger volume, heavier weight, inconvenient to carry and other defects, the purpose of the present invention is to provide an improved external OLED type lighting for camera or video camera, which can overcome the defects of the prior art
