Self-generating lighting modules and faucets

Abstract

The invention provides a self-generating lighting module and a faucet. The self-generating lighting module can be installed in the water outlet channel of the faucet, and includes a micro-hydraulic generator, an LED circuit board and a waterproof sealing member. When the water flow enters the water outlet channel of the faucet, the micro-hydraulic generator can generate electricity to supply the LED circuit board and the LED on it to emit light. The waterproof seal can seal the LED circuit board to the machine room of the micro-hydraulic generator, and completely isolate it from the water flow, so as to meet the requirements of relevant safety regulations in various countries, and no relevant safety certification is required. At least a part of the waterproof sealing member has light transmittance, through which LED light can pass through, so as to maintain good light transmittance and luminous intensity. The waterproof seal can also be used to change the diversity of light, and it is also helpful to assemble and fix the self-generating lighting module with the faucet, and can change the direction of water flow.

Description

Technical field: [0001] The invention relates to a faucet and its components, in particular to a self-generating lighting module and a faucet equipped with the self-generating lighting module. Background technique: [0002] Many existing patent technical documents have disclosed that lighting components are installed inside the faucet or at the water outlet, so as to provide lighting, light indication, decoration, and make the water flow produce different light changes, and even meet the requirements of energy saving. For example, US Patent No. US 6,774,584B2 discloses that a light source directly irradiates the water flowing from the outlet of the faucet, and the light source is at least two LEDs of different colors. A similar concept is to combine the lighting component with the water wave device, or install it at the outlet of the faucet. In addition to providing the function of illuminating the water flow, it can also be combined with a micro-hydraulic generator, so that...

AI Technical Summary

Problems solved by technology

[0003] As mentioned above, micro-hydraulic generators combined with LED circuit boards have been gradually installed and applied to various faucets. This kind of self-generating lighting device that uses the water flow through the faucet to generate electricity to supply the power required by LED lighting, its micro-hydraulic The generator and the LED circuit board are usually installed separately. The common disadvantage of this device is that a special space must be provided inside the faucet for the wiring between the micro-hydraulic generator and the LED circuit board to be accommodated, and the wiring must also be considered. The fixation and ease of installation can avoid water seepage and damage to lighting equipment, and even the risk of leakage. It is also necessary to consider whether the circuit will be twisted or bent during the configuration or operation of the faucet.

[0004] Another common self-generating lighting device mainly installs the micro-hydraulic generator and the LED circuit board together in a box or a water outlet housing, and then installs the box or water outlet housing on the water outlet of the faucet. Therefore, The whole is an external design, although it can avoid the internal space design and circuit configuration problems of the faucet, and the problems of water seepage and leakage are easier to overcome, but for users who pay attention to the consistency of texture, product appearance and integrated aesthetics, the external The traditional design is difficult to accept, and this kind of self-generating lighting device is usually screwed into the water outlet of the faucet, which will cause the water outlet position to be too low, easy to get dirty, and loose at the screw joint after frequent contact and collision. off or shaken
