Embodiment Construction
[0022] Such as Figure 1 ~ Figure 5 As shown, an intermittent illuminance detection device according to the present invention includes a base 1, and a photoelectric element opening and closing device for placing optoelectronic elements is installed in the bottom space of the base 1, and a driving photoelectric element is also installed on the base 1. The element opening and closing device rotates and drives the photoelectric element opening and closing device to rotate and extend out of the bidirectional angle motor 3 on the bottom surface of the base 1. In addition, in order to better limit the rotation angle of the two-way angle motor 3, the bottom of the bottom surface 11 of the base 1 is provided with an inner limit block 7 and an outer limit block for limiting the rotation angle of the short rod 2. Block 8.
[0023] The photoelectric element opening and closing device is a short rod 2. One end of the short rod 2 is connected to the output end of the bidirectional angle moto...

The invention belongs to an illuminance detection device for photoelectric components and in particular discloses an intermittent illuminance detection device. The intermittent illuminance detection device comprises a pedestal, wherein a photoelectric component opening / closing device for placing a photoelectric component is arranged at the bottom of the pedestal; and a driver for driving the photoelectric component opening / closing device to rotate and driving the photoelectric component opening / closing device to extend out of the bottom surface of the pedestal is arranged on the pedestal. Theintermittent illuminance detection device has the advantages that: when the photoelectric component is detected, the illuminated surface of the photoelectric component is not sheltered completely, and when the photoelectric component is not detected, the illuminated surface of the photoelectric component is sheltered completely, so that the accuracy of the detection result is effectively improved; and at the same time, the intermittent illuminance detection device has certain dustproof and rainproof functions, so that overlong illumination duration of the photoelectric component is avoided and the service life of the photoelectric component is guaranteed; in addition, the intermittent illuminance detection device has a better self-checking function, so when the external illuminance does not need to be detected, the illuminated component can be placed in a sealed darkroom, and the normal using performance of the photoelectric component is guaranteed by adopting a standard light source to perform self-checking and correction.
Description
Technical field [0001] The invention belongs to an illumination detection device of a photoelectric element, and in particular relates to an intermittent illumination detection device. Background technique [0002] At present, in the automatic detection of intermittent illuminance, such as the illuminance detection of the aging test of LED lighting lamps, the photoelectric element is usually directly placed on the point to be detected, and the control circuit is used to sample regularly for detection. Because the photoelectric element is exposed for a long time, the light-receiving surface of the photoelectric element will be blocked by dust, rain and other sundries, causing the measured data to be inaccurate; moreover, the photoelectric element is exposed to light for too long, which will also affect the performance of the photoelectric element; The self-inspection function of the photoelectric element during the inspection will also affect the inspection result. Summary of the...
