Embodiment Construction
[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0033] Such as figure 1 As shown, the switch protection device 10 (hereinafter simply referred to as the switch protection device) of the diving lighting fixture of this embodiment includes a rubber sleeve 12 . The inner cavity of the rubber sheath 12 is sealed with an external touch switch 22 of a lighting fixture for diving. Such as image 3 As shown, the tact switch 22 includes a contact portion 220 and a switch body 222 , and the tact switch 22 is fixed on a substrate 224 . Wherein, the contact portion 220 is disposed on the upper surface of the switch body 222 , and the lower surfa...

The invention relates to a switch protection device for a lighting fixture for diving and the lighting fixture for diving. It includes a rubber sleeve (12) for sealing an external touch switch (22), the touch switch (22) is located in the inner cavity of the rubber sleeve (12), and is connected to the diving lighting through an electric wire (24) covered with a waterproof insulating skin For a lamp, the touch switch is used to control the power on and off of the lamp, wherein the rubber sleeve (12) is filled with a filling liquid (14) which is electrically insulated, and the filling liquid (14) is a non-corrosive liquid. Filling fluid (14) is industrial oil or edible oil. Adopting the switch protection device of the diving lighting fixture and the diving lighting fixture of the present invention can improve the sealing performance of the switch protection device, and the thickness of the rubber sleeve only needs to meet the sealing strength, and there is no need to increase the thickness of the rubber sleeve due to water pressure. Therefore, the touch switch is easy to control, and the failure of the touch switch is avoided.
Description
technical field [0001] The invention belongs to the field of lighting. Specifically, the present invention relates to a switch protection device for a lighting fixture for diving and a lighting fixture for diving. Background technique [0002] As we all know, the external switch protection device used for diving lighting fixtures has strict requirements in terms of waterproof and water pressure resistance. In the prior art, the external switch protection device of the lighting fixture for diving generally only uses a rubber sleeve to seal and waterproof the electronic touch switch. However, the external switch protection device of this diving lighting fixture has the following disadvantages: (1) the waterproof level is not high; (2) the rubber sleeve placed in the water is easily deformed under deep water pressure, thereby causing the switch to malfunction; (3) ) Because the thickness of the rubber sleeve is too large, it needs a lot of force to compress it, making it diff...
