Description

Sound and light control energy-saving lamps

technical field

The utility model relates to the lighting field, in particular to an acousto-optic control energy-saving lamp.

Background technique

At present, civil lighting fixtures include: incandescent lamps, fluorescent lamps, high-pressure sodium lamps, etc. Incandescent lamps have limited luminous efficiency and relatively high energy consumption; fluorescent lamps have good luminous efficiency, but produce a large number of toxic substances and pollute the environment; high-pressure sodium lamps require high operating voltage and are easily damaged. LED (Light Emitting Diode, light-emitting diode) as a new type of environmentally friendly lighting source, compared with incandescent lighting, has high efficiency and low power consumption; compared with fluorescent lamps, no toxic substances are produced and is more environmentally friendly; compared with high-pressure sodium lamps, its operating voltage requirements are not high. And it is not easy to damage. In addition, the LED has a long service life, which is unmatched by other lights.

However, the use of LED lighting in the prior art does not adhere to the concept of energy saving. The existing LED lighting designs are all controlled by a power switch to turn on and off the lighting. If it is closed, the lighting lamp will always be on, that is, the existing LED lamp structure cannot automatically control the LED lamp on and off according to the specific needs of the external environment, which is undoubtedly a waste of resources.

Detailed ways

The utility model provides an acousto-optic control energy-saving lamp through which the acousto-optic controller collects external acousto-optic information, controls the LED energy-saving lamp to turn on and off according to the acousto-optic information, and achieves the purpose of energy saving.

As shown in Figure 1, it is a structural schematic diagram of the energy-saving lamp with acousto-optic control of the present utility model, including a lamp cap 1, a fixing plate 2, a light-emitting diode group 3, a lampshade 4, an acousto-optic controller 5, a lamp cap screw ring 6 and a lamp cap contact 7 . Lamp contact 7 is the live wire electrode terminal, and lamp cap screw ring 6 is the neutral wire electrode terminal; due to the limited brightness of a single light-emitting diode, to achieve a better lighting effect, generally multiple light-emitting diodes are used to illuminate at the same time to meet the lighting requirements; A plurality of light-emitting diodes form a light-emitting diode group 3 and are welded on a printed circuit board, and the printed circuit board is fixed by a fixing plate 2, and the fixing plate 2 is fixed inside the lampshade 4 in the form of a positioning groove; because the lampshade 4 is generally circular design, so the printed circuit board is generally also designed to be circular, but the design of the utility model is not limited to the circular design, and the shape of the printed circuit board can be designed into different shapes according to specific needs. The acousto-optic controller 5 is arranged inside the lampshade 4, and can be fixed by welding, or by brackets or other methods. Any feasible way that can realize the fixation of the acousto-optic controller 5 should belong to the protection scope of the present utility model; The positive and negative poles of the light controller 5 are respectively electrically connected to the electrode terminals of the lamp cap, the positive pole of the acousto-optic controller 5 is connected to the lamp cap contact 7 , and the negative pole of the acousto-optic controller 5 is connected to the lamp cap screw ring 6 . The acousto-optic controller 5 performs current limiting, step-down and rectification control on the 220V alternating current, and then inputs it through the positive and negative poles of the LED group 3 respectively in the form of direct current, so that the current flowing through each LED in the LED group 3 is consistent. , thereby improving the light efficiency.

The working principle of the embodiment of the present invention, as shown in Figure 2 and Figure 3, the circuit diagram shown in Figure 2 is made up of A, B, C, D four gates, and A gate is made up of microphone MC, resistance _R2 , _R3 and electric capacity C ₁ , C ₂ and other components form a sound control circuit, gate B is a light control circuit, gate C is a control circuit for controlling the LED light on and off, and gate D is a delay circuit for controlling the LED light on time. In the daytime, door C is in a closed state, even if there is sound from the outside, the signal output by door A cannot open door C, that is, the LED light does not work during the day and is in an off state; at night or when the light is dark, for example, when the illuminance is less than 31x As a standard, when the external illuminance is less than 31x, door B is unblocked, and the audio amplifier composed of door A and microphone MC collects a sound pressure greater than 30 decibels, then generates an output signal and sends it to door C, and door C receives the signal After that, the control circuit is turned on, the 220V voltage is connected, and sent to the control circuit shown in Figure 3. The control circuit supplies power to the light-emitting diodes D ₁₀ and D ₁₁ in the form of DC after current limiting, step-down and rectification. D ₁₀ , D ₁₁ lights up, and the LED light starts to illuminate. When the LED light is on, the delay circuit composed of gate D, capacitor C ₃ and resistor R ₇ starts to work. The timing range of the delay circuit is generally 0-3 minutes. For example, set the delay time to 40s. The timing circuit starts counting when the LED light is on. If there is no sound pressure greater than 30 decibels within 40 seconds of the LED light being on, that is, the C gate does not receive the output signal of the A gate, the LED light will automatically turn off after 40 seconds. At night, Gate A is always working to collect external sound pressure signals. Whenever the external sound pressure is greater than 30 decibels, Gate A will generate an output signal and send it to Gate C. Every time Gate C receives a signal, the delay The circuit starts timing again. If the LED is on when gate C receives a certain signal, and the delay circuit is timing, the LED light will continue to light from the latest received signal, and the delay circuit will start timing again. The time is 40s. Such repeated work enables the LED lamp to automatically control its on and off according to the needs of the external environment, reduces useless energy consumption, saves energy, and prolongs the service life of the LED lamp on the other hand.

The above disclosures are only a few specific embodiments of the utility model, but the utility model is not limited thereto, and any changes conceivable by those skilled in the art should fall within the protection scope of the utility model.
