Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] see Figure 1-Figure 61 , the light control LED structure includes an LED light, and also includes a hysteresis light control circuit for controlling the switch of the LED light, and the hysteresis light control circuit is connected with the LED light.

[0017] The present invention adopts 555 time base circuit to form hysteresis light control circuit, see Figure 1-Figure 17 , or use an operational amplifier to form a hysteresis light control circuit, see Figure 30-Figure 61 ; so as to ensure that when the background light is weak, such as at night or in the dark, the LED light can be turned on automatically, and the light emitted by the LED light itself is guaranteed to illuminate the environment, and at the same time, the light-controlled LED light cannot be extinguished by the light emitted by itself.

[0018] In this embodiment, the LED la...

Abstract

A light-control LED structure comprises an LED lamp and a delaying light control circuit for controlling an LED lamp switch. The delaying light control circuit is connected with the LED lamp. The delaying light control circuit is a 555 time-base circuit or an operational amplifier control circuit. The LED lamp is connected with a voltage stabilizing circuit. A switch circuit of the LED lamp is a single-audion switch circuit or a Darlington tube switch circuit or an MOS tube switch circuit. The delaying light control circuit is connected with the LED lamp, the delaying light control circuit is the 555 time-base circuit or the operational amplifier control circuit, accordingly, when background light is weak, for example, at night or in darkness, the LED lamp can be turned on automatically, the fact that light emitted by the LED lamp illuminates environment is guaranteed, and meanwhile the light-control LED lamp cannot be turned off by light emitted by the same. The structure is very suitable for public places where lighting is needed at night or in darkness, and the structure has the advantages of being simple, reasonable and flexible in operation.

Description

technical field [0001] The invention relates to a light control LED structure. Background technique [0002] At present, products that use mechanical switches to control the opening and closing of LED lights can only be controlled manually. LED lights controlled by electronic time-delay switches such as sound-light control or human body infrared sensor switch, after the delay of the electronic time-delay switch, the LED light goes out. LED lights with this structure are not suitable for use in elevator halls and other places that cannot be turned off at night. Lights for public places. Contents of the invention [0003] The object of the present invention is to provide a light control LED structure with simple and reasonable structure and flexible operation, so as to overcome the shortcomings in the prior art. [0004] A light-controlled LED structure designed according to this purpose includes an LED lamp, and its structural feature is that it also includes a hysteresis...
