Description

Technical Field

[0001] The utility model belongs to the technical field of street lamp lighting, and in particular relates to a tunnel adaptive street lamp lighting device. Background Art

[0002] Tunnel lights are special lamps used for tunnel lighting to solve the "black hole effect" or "white hole effect" caused by sudden changes in brightness when vehicles enter or exit tunnels. The light source generally uses sodium lamps, metal halide lamps or electrodeless lamps. Tunnels are special sections of high-grade highways. When vehicles enter, pass through and exit tunnels, a series of visual problems will occur. In order to adapt to the changes in vision, additional electro-optical lighting devices need to be installed. The shell of the lamp is made of environmentally friendly alloy materials with high strength and good toughness. The transparent parts are reinforced tempered glass, which is dust-proof and waterproof, corrosion-resistant and rust-proof, and has strong resistance to strong collision and impact; multi-channel shockproof structure and high-tech surface spraying treatment, various close-range high-intensity and high-frequency vibrations cannot affect the lamps, and they can work stably for a long time in high-frequency vibration and humid, high-temperature environments such as workshops, roadbeds, and tracks. They have good electromagnetic compatibility and will not interfere with the power transmission network. Tunnel lighting devices with multiple functions. Chinese patent CN204494213U discloses "a tunnel adaptive street lighting device", including controllable adjustable lamp components, non-controllable lamp components and controllers, which can automatically adjust the brightness of tunnel street lights according to the light intensity outside the tunnel, so that the visual adaptation of the vehicle driver's eyes is in a gradual process, so that the driver can always see the road conditions in front of the vehicle, reducing traffic accidents caused by temporary "blindness" of the driver due to changes in light. When this type of tunnel lighting needs to be repaired and the bulbs are replaced, it is difficult for the staff to disassemble and assemble the conventional integrated bulb rack; in addition, the heat dissipation port of the bulb rack is easily infiltrated with dust in harsh outdoor conditions, thus affecting the normal use of the lighting device.
