Embodiment Construction
[0023] like figure 1 The above-mentioned is a high-power square lighting lamp, which includes a main body 1 of the lighting fixture and a trigger 2 arranged on the main body 1 of the lighting fixture. When the trigger 2 lights up the lighting fixture, it will generate a lot of heat. Sealed watertight, so the internal air pressure will increase due to temperature rise, which will affect the performance of the internal parts of the trigger. For this reason, a ventilating structure is provided on the housing of the trigger 2 . Hereinafter, taking the breathable structure on the shell of the trigger 2 as an example, how to implement the waterproof and breathable structure for the lamp of the present invention will be introduced in detail.
[0024] like figure 2 , image 3 and Figure 4 As shown, there is an annular first water retaining wall 21 on the outer side of the housing 20 of the trigger 2, and the first water retaining wall 21 has four first notches 211 evenly distrib...

The invention relates to a water-proof ventilating structure for lamps, which is provided with a first water blocking wall and a second water blocking wall which are nested, wherein a ventilating channel is positioned in the second water blocking wall; the first water blocking wall is provided with a plurality of first gaps which are uniformly distributed along the circumferential direction; eachfirst gap is provided with a water blocking plate opposite to the first gap; the second water blocking wall is provided with at least one second gap for introducing gas; each second gap and each first gap are arranged alternately; the second water blocking wall is provided with an extending segment which is in a circular arc shape and extends from the edge of the second gap to two sides; and any water which flows into the first water blocking wall from one first gap can flow out of the other first gaps and can not flow into the second gap, thereby ensuring ventilation and thoroughly realizingwater-proof purpose simultaneously.
Description
technical field [0001] The invention relates to high-power lamps, and more specifically, relates to a waterproof and breathable structure for high-power lamps. Background technique [0002] High-power sealed lamps, such as some large square lamps, will generate a lot of heat when they are working or their triggers are triggered. Since the shell of the lamp is sealed, the air pressure inside the lamp will increase due to the temperature rise. And increase, which will affect the parts inside the lamp burst damage due to high pressure. In order to prevent the internal pressure of the lamp from being too high, it is necessary to install a ventilating structure on the shell of the lamp. When the internal pressure of the lamp changes, it can exchange gas with the outside to ensure the air pressure balance inside and outside the lamp. The existing air-permeable structure cannot be completely waterproof, which will greatly affect the performance of the lamp, and even cause damage t...
