An outdoor flood light for lighting engineering

Abstract

The invention discloses an outdoor floodlight for lighting engineering. When used, water is first discharged through the water pipe valve, and the water from the soft water pipe is sprayed from the nozzle to spray the light source transmission glass panel to moisten the panel, and then, through The joint of the external connecting section of the air pipe and the mobile pneumatic device are connected to the air pipe to supply air, so that the telescopic rod of the small cylinder expands and contracts, thereby driving the brush to advance and retreat, causing the brush to rub the glass panel to remove dust, dirt, dirt, etc. Rubbing while spraying water achieves a good cleaning effect, which increases the transparency of the light source transmitted through the glass panel, and the floodlight irradiation intensity is stronger, the illuminated body is clearer, and the effect is better.

Description

technical field [0001] The invention relates to a lighting appliance, in particular to an outdoor projection lamp for lighting engineering. Background technique [0002] Floodlights are mainly used for advertising, exhibitions, stage lighting, decorative effects, festival lighting, product sales and other lighting appliances. However, outdoor large-scale advertisements and high-rise building decoration floodlights are different from other lighting fixtures. Fixed for a long period of time, exposed to the outside for a long time, exposed to the sun, rain, wind and rain, outdoor large-scale advertisements, high-rise building decoration floodlights all have the best effect from bottom to top, but the floodlights The light source is transmitted through the glass panel. During long-term use, dust and dirt will fall on the surface of the glass panel and adhere to the surface. When there is indirect light rain or raindrops, the rainwater will combine with the dust in the air to for...

[0002] Floodlights are mainly used for advertising, exhibitions, stage lighting, decorative effects, festival lighting, product sales and other lighting appliances. However, outdoor large-scale advertisements and high-rise building decoration floodlights are different from other lighting fixtures. Fixed for a long period of time, exposed to the outside for a long time, exposed to the sun, rain, wind and rain, outdoor large-scale advertisements, high-rise building decoration floodlights all have the best effect from bottom to top, but the floodlights The light source is transmitted through the glass panel. During long-term use, dust and dirt will fall on the surface of the glass panel and adhere to the surface. When there is indirect light rain or raindrops, the rainwater will combine with the dust in the air to form sewage drops on the glass. The surface of the panel is not glued tightly, and dirt (scaling) will be formed on the surface of the glass panel after a long time, the light transmittance of the glass panel will be weakened, the brightness of the irradiated object will be reduced, and the decorative effect on the irradiated object will be deteriorated; High-altitude lights and high-rise building exterior wall decoration floodlights are suspended in mid-air and cannot be cleaned. Even cleaning requires very professional high-altitude workers, and the life safety guarantee for high-altitude workers is also limited.
