Embodiment Construction

[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] Such as figure 1 , figure 2 , image 3 As shown, an anti-condensation buried lamp includes a main housing 1 , a light source assembly, a plano-convex mirror assembly, a face cover assembly and a respirator 21 . The main housing 1 is provided with a lamp cavity 12 with an open top. Such as Figure 8 , Figure 9 As shown, the top is provided with the top surface 15 of the flange structure, the bottom is sealed, and the breathing cavity 11 and the power line hole 13 are provided. The power cord hole 13 is used for the power cord to pass through the inside and outside of the lamp cavity 12 . Breathing chamber 11, such as Figure 4 , Figure 5 As shown, it is a hexagonal structure with an open lower end. Vertical grooves 113 are arranged on the hexagonal sides of the breathing cavity 11 . The breathing cavity 11 communicates with the lamp inner c...

Abstract

The invention discloses a condensation-preventing ground buried lamp. A breathing cavity with an opening formed in the lower end is formed in the bottom of a main shell body of the ground buried lamp,the breathing cavity communicates with an inner cavity of the lamp through a breathing hole, and a breathing device consists of a head part and a threaded column; the head part is of a hexagonal cylindrical structure which is hollow inside, and a sided hole is formed in each of the six side faces of the head part; a thread is formed in the cylindrical surface of the threaded column, and a circular airway along the center of the cylinder is arranged in the threaded column; the circular airway is separated from the hollow part inside the head part through a breathing membrane; the breathing cavity is of a hexagonal structure and matched with the head part of the breathing device; the inner diameter of the breathing hole is matched with the threaded column, the head part of the breathing device is arranged in the breathing cavity, and the threaded column of the breathing device enters the inner cavity of the lamp by penetrating through the breathing hole and is fixed at the bottom of themain shell body through nuts; and a vertical groove is formed in each of the six side faces of the breathing cavity, and the opening of the lower end of the breathing cavity is covered by a steel net. The condensation-preventing ground buried lamp can prevent the breathing device from being blocked and damaged.

Description

technical field [0001] The present invention relates to buried lamps. Background technique [0002] Buried lamps on the market often have water droplets on the glass surface. The reason is that after the lamp is turned on, the temperature in the cavity rises and water vapor is generated. Because it is a closed shell, the water vapor cannot be discharged. When the lamp is turned off again, the water vapor cools and electrostatically adsorbs on the glass. Some designs use respirators to pre-exclude water vapor, but due to unreasonable structural design, they do not play the role of exhaust. The following two situations often occur: [0003] (1) As a result, the respirator is blocked, the lamp is still closed, and it does not discharge water vapor, and condensation will also occur. [0004] (2) The impact of external stones will cause damage to the respirator, and water will directly enter the lamp. Contents of the invention [0005] The problem to be solved by the invent...
