Light-sensing structure with linear brightness change with environment

The present invention relates to a light-sensing structure with a linear brightness change according to the environment, especially for a single lamp body with an automatic dimming function, which can gradually adjust the brightness of the changed light in a linear manner, especially the light mode of the lamp body. Groups, power modules, controllers, linear dimmers, and light sensors.

Conventionally, a lamp having an automatic dimming function is usually provided with a plurality of lamp bodies (for example, a lamp tube or a bulb) and a set of light sensing modules on a cover or a lamp holder of the lamp, and the light sensing module is respectively passed through a plurality of pieces. The power line is connected to each of the lamp body, and the light sensing module can sense the ambient brightness around the cover or the lamp holder. The ambient brightness generally includes the natural light (for example, daylight) in the environment surrounding the lamp and the light body. Lighting, and such lamps can adjust the brightness of each lamp body according to the brightness of the environment, for example, when the brightness of the environment is strong, the brightness of each lamp body is lowered; when the brightness of the environment is weak, Raise the brightness of each lamp body to maintain the brightness of the light in the environment where the lamp is located.

However, the above-mentioned conventional technique for adjusting the light-emitting brightness of each lamp body according to the ambient brightness is to directly switch the current brightness of the lamp body to the brightness of the light to be adjusted, for example, the current brightness of the lamp body is 40 lumens. Directly changing to a luminous brightness of 60 lumens, it is easy to cause the light to flash due to a sudden change in the brightness of the light; in addition, it is known that the light sensing module disposed on the cover or the lamp holder must simultaneously connect and adjust the plurality of groups of lamps The brightness of the light causes the structure of the light-sensing module and each group of lamps to be complicated and large; and if multiple lamps are installed in different environments (for example, different rooms, window areas, or not) In the window area, in the case where the light-emitting brightness is synchronously adjusted by the same light-sensing module, the light-emitting brightness of the lamp body of each environment is the same, and it is difficult to adjust the light-emitting of the lamp body for the actual needs of each environment. brightness.

In view of this, the creators of the present invention have developed their creations to overcome the shortcomings of the prior art described above by virtue of their many years of experience in the production, manufacture and design of lamp bodies.

Therefore, the main purpose of the present invention is to provide a light-sensing structure with a linear brightness change according to the environment, comprising: a light-emitting module; a power-on module, and the light-emitting module are combined with each other; The controller is disposed in the power module, and is powered by the power module to drive the light module to emit light. The controller is preset with a brightness luminance data; a linear dimmer And electrically connected between the controller and the light emitting module; and a light sensor disposed on the outer wall of the power receiving module, electrically connected to the controller, the light sensor capable of sensing the brightness of the external environment, and generating An ambient brightness data; the controller is capable of gradually adjusting the brightness of the light emitting module in a linear manner via the linear dimmer according to the brightness brightness data and the ambient brightness data.

Accordingly, when the controller adjusts the light-emitting brightness of the light-emitting module, the brightness of the light-emitting brightness is linearly changed by the control mechanism of the linear light dimmer, and the light flashes without causing a sudden change in the light-emitting brightness. In the case of motion, and each light body is provided with a separate light sensor on the power module, the structure is simplified, and the independent light sensor can accurately sense the actual light brightness of the environment around the lamp body, and then The brightness of the lamp body can be adjusted according to the actual needs of each environment. It is easy to change the brightness of the luminaire with the automatic dimming function and the problem that the illuminating brightness and the structure of the light sensing module are complicated and large.

According to the above-mentioned light-sensing linear brightness-changing lamp body structure, the controller can compare the brightness value of the brightness data and the ambient brightness data with the brightness value of the ambient brightness data, which is higher than the brightness data. When the brightness value is used, the brightness of the light-emitting module is lowered, and when the brightness value of the brightness data of the environment is lower than the brightness value of the brightness data, the brightness of the light-emitting module is raised.

The light-emitting module and the power-receiving module can be combined with each other to form one of a lamp tube, a light bulb and a light bar.

The light-emitting module can be one of a fluorescent lamp and an LED lamp.

The light-sensing structure is connected to the controller by an AC-DC converter and a DC filter.

The power module 2 can include a power-receiving end of the lamp tube and a spiral base of the light bulb. The lamp terminal A can be installed on the lamp cover or the lamp holder (not drawn) of the external lamp by the power module 2 to receive power from the external mains power supply. In this embodiment, the lamp body A combined with the power module 2 and the power module 2 is a lamp body A of the lamp type, and the power module of the light module 1 is respectively provided with a power receiving module. 2, 20.
