Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to an anti-glare structure for a parking lot monitoring camera. Background Art
[0002] In the past decade, the lighting industry, one of the important electrical industries, has undergone disruptive changes. The most important thing is that the light source has undergone a major change, and LED light sources are now widely used. Moreover, the performance of LED light sources far exceeds that of the past HID light sources. LED lamps are currently widely used in lighting design and are widely used in various occasions. They have the characteristics of high light efficiency, good color rendering, no flicker, instant start, and no fear of vibration.
[0003] Compared with light sources such as HID and incandescent lamps, the efficiency of LED light sources in LED lamps is very high, generally reaching 140lm / W. However, unlike the HID gas discharge lamp light source commonly used in the past, the light beads are very small, and the optical design method of the emitter for light flux distribution of HID lamps is usually not used. HID light sources are generally larger, and the emitters of HID lamps that perform light distribution are usually very large. Different light distribution curve requirements will require different emitters to cooperate. Different HID light source powers or HID light source types will also require different emitters. In general, there are many types of emitters in HID lamps, and the size of the lamps is also larger.
[0004] LED light beads used in LED lamps are very small, and the corresponding optical components for light distribution can also be very small. Generally, components such as lenses corresponding to LED light beads distributed on a flat plate are used. Although the LED light beads are very small, the luminous brightness is very high, resulting in extremely high brightness on the lens surface. In addition, LED light beads are generally 1W-5W, and lamps usually use dozens of LED light beads, which results in a large luminous surface. In addition, the glare of the lamp is proportional to the brightness of the light source and the size of the luminous surface. This causes LED lamps to generally produce severe uncomfortable glare, and even disabling glare, especially in parking lots. If you are not careful, it may cause serious accidents. Therefore, we propose an anti-rotation structure for parking lot surveillance cameras. Utility Model Content
