Abstract
Description
Technical Field
[0001] This utility model relates to the field of stage lighting technology, and in particular to a lens defogging structure for a stage light. Background Technology
[0002] Stage lighting effectively enhances the stage performance effect, and stage lights are commonly used stage lighting equipment. Stage lights can concentrate the light source on a single focal point, thereby making the light source more focused or dispersed, forming single or multiple beams, thus creating a better stage lighting effect. During a stage performance, stage lights are arranged around the stage, suspended in the air, with beams shooting onto the stage in multiple directions to create stage lighting effects.
[0003] The stage light includes a base, a lamp holder that can be rotatably mounted on the base, and a lamp head that can be swung on the lamp holder. The lamp head has a lens mounted on its top and contains an illumination lamp and several lighting effect modules arranged sequentially above the illumination lamp. The light beam formed by the illumination lamp passes through the several lighting effect modules and the lens, and the lighting effect modules change the lighting effects.
[0004] However, when the lens temperature of the stage light is lower than that of the operating environment, water vapor easily condenses on the lens surface, which greatly affects the efficiency of the stage light fixture and the clarity of the pattern. In addition, stage lights are usually suspended in the air when in use, and the incident surface of the lens is located inside the light fixture. If water vapor needs to be removed manually, it will consume a lot of manpower and resources. Utility Model Content

Each defogging unit includes a connecting frame, a defogging fan, and a control circuit board. Each connecting frame forms a first mounting section and a second mounting section connected by a short and a long section, and the included angle between the first and second mounting sections at the connection point is an obtuse angle.

[0021] Please see Figure 1 , Figure 2 A lens defogging structure for a stage light is installed inside the lamp head of the stage light, comprising two sets of defogging units 10; the lamp head includes a lamp housing 21 and a lamp head bracket 22 disposed inside the lamp housing 21, the lamp head bracket 22 is provided with a lens fixing frame 221 at the top and two side frames 222 connected to the lens fixing frame 221 on opposite sides, a light-emitting lens 23 is installed on the lens fixing frame 221, and a focusing module 24 capable of being raised and lowered relative to the light-emitting lens 23 is provided between the two side frames 222;
[0022] The two sets of defogging units 10 are positioned at the front and rear ends of the lamp head bracket 22, corresponding to the incident front of the light-emitting lens 23, and the two sets of defogging units 10 are mirror-symmetrical.
[0023] See also Figure 3 , Figure 4 and Figure 5 The defogging unit 10 includes a connecting frame 11, a defogging fan 12, a control circuit board 13, and a light shield 14. Each connecting frame 11 has a first mounting section 111 and a second mounting section 112 connected in the middle, with the included angle α at the connection point of the first mounting section 111 and the second mounting section 112 being an obtuse angle. The defogging fan 12 is mounted on the first mounting section 111 to blow air onto the incident surface of the light-emitting lens 23 to remove fog. The control circuit board 13 is mounted on the second mounting section 112 to control the defogging fan 12 on the same connecting frame 11. The lifting or focusing operation of the operation and focusing module 24; the first mounting section 111 and the second mounting section 112 are each provided with a first connecting edge 101 on one side facing the adjacent side frame 222 and a second connecting edge 102 extending inward at their bottom, so that the first connecting edge 101 can be detachably connected to the side frame 222; the light shield 14 is detachably mounted on the bottom of the connecting frame 11 through the second connecting edge 102, and a light-transmitting area is formed between the two light shields 14 for the light path to pass through, and the edge of the light shield 14 facing the light-transmitting area is recessed with an arc-shaped opening 141 in the middle, so as to block and shape the light path.
