Photo-driving light with a timer

Light control lamp with timing function

This creation is about a light-controlled luminaire, especially a light-controlled luminaire with timing function.

Conventional light-controlled lamps, such as the new bicycle warning lamp of the Republic of China No. M360187, connect a photoelectric switch between a power source and a light bulb so that the photoelectric switch can sense the surrounding environment. The brightness determines whether or not it is turned on. Thereby, the photoelectric switch can be closed when the light of the external environment is insufficient, and the power provided by the power source is sent to the light bulb to make the light bulb emit light to provide an illumination function; otherwise, when the light of the external environment is sufficient, The photoelectric open relationship is in an open state, and the power supplied by the power source is stopped from being sent to the light bulb to avoid waste of energy. With the above-mentioned circuit structure, the conventional light-controlled luminaire can be controlled at any time according to the brightness of the external environment, achieving rapid response and effectively saving power consumption.

However, the above-mentioned conventional light control lamps still have the following disadvantages: the conventional light control lamps can only be opened and closed according to the brightness of the external environment, and cannot be further automatically opened by the user according to the manner of use thereof. Closed control. For example, when the user does not need the light source to illuminate in the middle of the night, the conventional light-controlled lamps cannot be automatically turned off according to the demand to save energy, which is a waste of energy. In particular, for light-controlled luminaires that are connected to the city grid road without a power line and that use only solar energy or wind power for power generation and energy storage, the above-mentioned shortcomings are more likely to cause power shortage caused by improper energy consumption, which may make the conventional light-controlled luminaire Only a weak light source can be provided when the user needs sufficient illumination. For the above reasons, it is necessary to further improve the above-mentioned conventional light control lamps.

The purpose of this creation is to provide a light-controlled luminaire that can automatically open and close according to the brightness of the surrounding environment, and can control its continuous operation time to achieve energy saving.

Another object of the present invention is to provide a light-controlled luminaire that can be stopped at the user's request to change the mode of operation to achieve an increased operational margin.

In order to achieve the above-mentioned creative purposes, the technical means and the functions that can be achieved by the technical means include: a light control lamp comprising a power input port, a photosensitive timing module and a lighting unit. The power input is for receiving power. The photosensitive timing module is connected in series to the power input port, the photosensitive timing module has a photosensitive element, and is provided with a brightness threshold value and an on-time range, and the brightness of the photosensitive timing module measured by the sensing element is less than The luminance threshold value and the power is transmitted within the on-time range. The light emitting unit is connected in series to the photosensitive timing module. In this way, energy saving effects can be achieved.

In order to make the above and other objects, features and advantages of the present invention more comprehensible, the preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings: FIG. It is a system architecture diagram of the light control luminaire of the first embodiment of the present invention. The light control lamp comprises a power input port 1, a light sensing timing module 2 and a light emitting unit 3, wherein the power input port 1, the photosensitive timing module 2 and the light emitting unit 3 are connected in series in series.

In detail, please refer to Figures 1 and 2, the power input port 1 forms part of the surface of the light control lamp to receive power for driving the light control lamp. Wherein, the type of the power input port can1 can be a spiral type lamp holder as shown in FIG. 2 for connection to the city grid road; however, it can also be of any type according to the use requirements, so as to be applicable to other materials such as dry batteries, solar energy or Various forms of DC or AC power sources, such as wind energy. In addition, when AC power (such as a provider of a power grid) is to be used as the power source of the light control lamp of the present invention, the power input port 1 may be additionally provided with a rectifier to rectify and stabilize the input power.

The photosensitive timing module 2 is electrically connected to the power input port 1 for transmitting the power of the power transmission port 1. The photosensitive timing module 2 has a photosensitive switch unit 21 and a timing switch unit 22, and the photosensitive switch unit 21 and the timing switch unit 22 are connected in series. Here, as shown in FIG. 1, the power input port 1 can be connected by the photosensitive switch unit 21, and the timing switch unit 22 is connected to the light-emitting unit 3. In detail, in the embodiment shown in FIGS. 1 and 2, the photosensitive switch unit 21 has an electronic switch 211 and a photosensitive element 212, wherein the electronic switch 211 is serially connected to the timing switch unit 22, and the The photosensitive element 212 is exposed on the surface of the light control lamp and electrically connected to the electronic switch 211. Thereby, when the photosensitive element 212 senses that the brightness of the external environment of the light control lamp is less than a brightness threshold, the electronic switch 211 is actuated to be in an on state to transmit power to the timing switch unit 22; If the brightness of the external environment of the light control lamp is not less than the brightness threshold, the photosensitive element 212 causes the electronic switch 211 to be in an off state, and stops transmitting power to the timing switch unit 22. Therefore, the photosensitive switch unit 21 can determine the timing of supplying power to the timing switch unit 22 according to the brightness of the external environment. The timing switch unit 22 is configured to have an on-time range, and the timing switch unit 22 has a time setting component 221 for the user to set the on-time range, thereby determining that power is initially sent to the timing switch unit 22, The length of time during which power transmission is performed by the timing switch unit 22. The limitation of the on-time range may be: unlimited, limited to 2 hours, limited to 5 hours, or limited to 8 hours, and the like. Alternatively, the timing switch unit 22 can also have an electronic clock built in, and the on-time range is a length of time between a first time and a second time, so that the user sets the conduction time by the time setting component 221. The first time and the second time of the range determine the time at which the power can pass through the timekeeping switch unit 22. Under such an embodiment, the limitation of the on-time range may be: 7:00 to 12:00 in the evening or 7:00 to 10:00 in the evening of the weekday.

The light-emitting unit 3 is electrically connected to the timing switch unit 22 of the light-sensing timing module 2, so that when the electronic switch 211 is in the on-state and belongs to the on-time range, the light-sensing module 2 receives the light-sensing module 2 Power is input to the power of port1, which in turn produces light. In addition, in order to enable the light-emitting unit 3 to generate a stable light source, the light generated by the light-emitting unit 3 is preferably not irradiated to the photosensitive element 212 to prevent the photosensitive element 212 from sensing the light of the light-emitting unit 3. Actuating the electronic switch 211 is in an off state, which will cause the electronic switch 11 to continuously switch.

With the above structure, the light control lamp of the first embodiment of the present invention can be automatically opened and closed according to the brightness of the surrounding environment, and the user can adjust the on-time range of the timing switch unit 22 according to requirements, thereby controlling the light of the creation. Control the continuous operation time of the lamps.
