The higher the temperature, the greater the pressure, which will affect the strength of the light-transmitting plate 4; and when the temperature drops suddenly, the air pressure in the cavity between the light-transmitting plate 4 and the lens 2 is low, lower than the external air pressure. When it rains, a siphon effect is easily generated, and water will be sucked into the cavity, affecting the sealing effect. By providing the breathing hole 14 and the breathable valve 15, the internal air pressure of the lamp is always balanced with the external atmospheric pressure in any state, avoiding the influence of the air pressure in the cavity.
