Abstract

The present invention relates to a sensing type lamp fixture capable of automatically adjusting brightness reference, and brightness sensing module and adjustment method thereof. While lightening the sensing type lamp fixture, a brightness reference adjustment procedure is executed to detect a lightening environment brightness value for determining whether the lightening environment brightness value is greater than a daytime brightness reference value or not.

As a result, the present invention may automatically adjust the daytime brightness reference value after lightening the lamp fixture, so as to prevent the sensing type lamp fixture from being turned off again due to too high the instant brightness during lightening, and avoid the occurrence of repeated lightening and turning off of the sensing type lamp fixture.

Description

Inductive luminaire with automatic brightness adjustment and brightness sensing module thereof and adjustment method thereof

The invention relates to an inductive lamp and a brightness sensing module thereof, and a brightness reference adjustment method built in the brightness sensing module, in particular to an inductive lamp and a brightness sensing module thereof and an adjusting method thereof for automatically adjusting a brightness reference.

Due to the rapid development of various technologies today, the concept of smart houses has gradually taken shape, and the most popular related products in smart houses are inductive lamps.

Inductive luminaires are mainly equipped with sensors in the luminaires, which are controlled by sensors to illuminate and ignite the luminaires. An existing inductive luminaire is equipped with a brightness sensing module, which is based on the ambient brightness measured by the brightness sensing module. Bright and point-off lamps, which can automatically illuminate the lamps at night, and actively extinguish the lamps during the day, in addition to the high convenience, it also helps to save energy.

In the existing inductive lamp, the brightness sensing module has a built-in daytime brightness reference value, a night brightness reference value, and a lamp lighting control program. The lamp lighting control program includes the following steps: detecting the ambient brightness to obtain an environment. Luminance value; illuminating and igniting the luminaire according to the comparison of the ambient brightness value and the daytime and night brightness reference value, wherein the illuminating device is lit when determining that the ambient brightness value is less than the night brightness value; After that, it is judged that the environment is bright. When the degree value is greater than the daytime brightness reference value, the lamp is turned off.

In this way, it is possible to control the inductive lamp to automatically illuminate/deactivate the inductive lamp when the ambient brightness is lower/higher than the daytime brightness reference value (ie, it is determined to be night), but the use is very flawed; The light environment of the luminaire installation environment is high. For example, when the wall is white or close to the reflector, the sensor will immediately detect that the ambient brightness is higher than the daytime brightness reference value and then turn off the luminaire. After the lamp is turned off, the ambient brightness is detected to be lower than the night brightness reference value, and the lamp is turned on, which will cause the inductive lamp to be turned on and off, which causes troubles in use, and therefore must be improved.

In view of the technical defect that the brightness sensing module of the existing inductive lamp has a situation of repeatedly lighting and extinguishing when the lamp is automatically lit, the present invention provides an inductive lamp and a brightness sensing module thereof and an adjustment thereof for automatically adjusting the brightness reference. method.

The inductive lamp for automatically adjusting the brightness reference includes a lamp body and a control circuit. The control circuit is disposed in the lamp body, and the control circuit includes a brightness sensing module and a power module. The power module is connected to the lamp body, and the brightness sensor module is connected to the power module to control whether the power module outputs DC power or not to light and extinguish the lamp body, and the brightness sensing module The preset has a daytime brightness reference value, and has a brightness reference adjustment program built therein, which executes the brightness reference adjustment program after lighting the lamp body, and the brightness reference adjustment program detects the ambient brightness when the lamp is lit to obtain a light. The ambient brightness value, and when it is determined that the brightness of the ambient light is greater than the daytime brightness reference value, a new daytime brightness reference value is generated, and the new daylight is bright The reference value of the degree is greater than the brightness value of the ambient light, and the new daytime brightness reference value is used as a basis for deciding whether to extinguish the lamp body.

Moreover, in order to achieve the above purpose, the inductive lamp body brightness reference adjustment method presets a daytime brightness reference value, and after lighting an external lamp body, performing the following steps: detecting the ambient brightness to obtain a light ambient brightness value; Determining whether the brightness value of the light environment is greater than the daytime brightness reference value; if the light environment brightness value is greater than the daytime brightness reference value, generating a new daytime brightness reference value, and the new daytime brightness reference value is greater than the light ambient brightness value; The new daytime brightness reference value is used as the basis for deciding whether to extinguish the lamp body.

Since the brightness sensing module in the inductive lamp performs the brightness reference adjustment program after lighting the lamp body, the ambient brightness of the lamp body after lighting is measured, and the daytime brightness reference value is reset, so that the daytime brightness reference value is greater than the light environment. The brightness value, whereby if the inductive lamp is installed in an environment with high light reflectivity, after it is lit, the daytime brightness reference value is automatically raised by the brightness reference adjustment program, so that the inductive lamp is not caused by the reflected light source. Off, this can prevent the inductive luminaire from being constantly lit up.

Referring to FIG. 1 and FIG. 2 , the inductive lamp for automatically adjusting the brightness reference of the present invention comprises a lamp body 10 and a control circuit 20 . The control circuit 20 includes a brightness sensing module 21 and a power module 22 . The module 22 is connected to the lamp body 10, and the brightness sensing module 21 is connected to the power module 22 to control whether the power module 22 outputs power or not to illuminate and ignite the lamp body 10.

The brightness sensing module 21 is preset with a daytime brightness reference value day_level and a night brightness reference value night_level, and the brightness sensing module 21 has a lighting determination program, a brightness reference adjustment program, a correction program, and a bit of extinction. a determining program, wherein the lighting determining program is as shown in FIG. 3, comprising: detecting an ambient brightness when the lamp is turned off to obtain a light-off ambient brightness value Lux _off (S11); determining that the light is off ambient brightness value Lux _off Whether it is less than the night brightness reference value night_level (S12), if not, controlling the power module 22 not to output power (S13), not lighting the lamp body 10; if so, controlling the power module 22 to output power (S14) The lamp body 10 is turned on, and the brightness reference adjustment program is started (S20).

Please further refer to FIG. 4 , the brightness reference adjustment program includes: detecting the ambient brightness of the lamp body 10 after lighting to obtain a light ambient brightness value Lux _on (S21), which is continued by the brightness sensing module in this embodiment. Detecting the ambient brightness of the lamp body 10 after lighting for a detection time (such as 5 to 10 seconds, the stabilization time required for general brightness detection) to obtain a relatively accurate brightness value of the light environment; determining whether the brightness value of the light environment Lux _on is greater than The daytime brightness reference value day_level (S22); if the light ambient brightness value Lux _{on is} greater than the daytime brightness reference value day_level, the daytime brightness reference value day_level is reset, a new daytime brightness reference value day_level_new is generated, and the new daytime brightness is generated. The reference value day_level_new is greater than the light ambient brightness value Lux _on (S23), and the execution of the click-off determination process is started, and the new daytime brightness reference value day_level_new is used as a basis for deciding whether to extinguish the lamp body 10 (S24); If the brightness value Lux _{on is} not greater than the daytime brightness reference value day_level, the execution of the point-off determination program is directly started to be preset. The daytime brightness reference value day_level is used as a basis for deciding whether or not to turn off the lamp body 10 (S24).

Please refer to FIG. 5 and FIG. 6 further. The following detailed steps of resetting the daytime brightness reference value day_level (S23) include: calculating a brightness adjustment value ΔLux (S231), and the brightness adjustment value ΔLux is light. The difference between the ambient brightness value Lux _on and the daytime brightness reference value day_level, that is, ΔLux=Lux _on -day_level; multiplying the brightness adjustment value ΔLux by a multiple value K, and the original daytime brightness reference value day_level The addition is made as the new daytime luminance reference value day_level_new (S232), that is, day_level_new = day_level + KΔLux, wherein the multiple value K may preferably be a value between 0.1 and 3.

The main purpose of the brightness reference adjustment program is to increase the daytime brightness reference value day_level, and to adjust the new daytime brightness reference value day_level_new as the basis for turning off the lamp body 10, so that after the brightness reference adjustment program is executed, the execution can be performed. For the point-off determination procedure, please refer to FIG. 7. The point-off determination program includes: preset a daytime determination time value (for example, set to 25 seconds) (S31); periodically detecting the ambient brightness of the lamp body 10 after lighting And periodically obtain a new light-bright environment brightness value Lux _new (S32); determine whether the new light-bright ambient brightness value Lux _new is greater than the daytime brightness reference value (day_level or day_level_new) (S33); if the new light is bright ambient brightness value Lux _new If it is less than the daytime brightness reference value (day_level or day_level_new), it returns to the step of periodically detecting the ambient brightness (S32); if the new light-on ambient brightness value Lux _{new is} greater than the daytime brightness reference value (day_level or day_level_new), the timing starts. (S34) detecting a new and bright ambient light luminance value is greater than the day to maintain Lux _new luminance value day_level_new reference time (S35); determining a new ring lights Whether the brightness value is greater than the day to maintain Lux _new reference luminance value is greater than the time of day value determination time (S36), if yes, determines that day, so that the power module 22 stops the output of the power source blinking lamp body 10 (S37) If not, the process returns to the step of periodically detecting the ambient brightness of the lamp body 10 after lighting (S32).

The brightness reference adjustment program mainly adjusts the daytime brightness reference value when the brightness of the environment is suddenly increased when the lamp body 10 is turned on. Therefore, if there is other strong light interference at the moment when the lamp body 10 is lit, the daytime brightness reference value is adjusted. If it is too high, the click-off determination program determines that the daytime condition may be misaligned. For this reason, the brightness reference adjustment program may further store the brightness ambient brightness value, and after the brightness reference adjustment program is executed, the correction procedure is executed, please further Referring to FIG. 8, the correction program includes: preset a determination correction time value (for example, can be set to 5 seconds) (S41); periodically detecting the ambient brightness of the lamp body 10 after lighting to periodically obtain a new light environment. Luminance value Lux _new (S42); determine whether the new light ambient brightness value Lux _new is less than the brightness ambient brightness value Lux _{on the} brightness reference adjustment program Lux _on (S43); if the new light ambient brightness value Lux _{new is} not less than the brightness reference adjustment light bright environment program stored brightness value Lux _on, no operation, and to return to ambient brightness of the lamp body 10 periodically detects lighting of Periodically to obtain new lights environment brightness Lux _new the step (S42); if the new lights environment brightness Lux _new smaller than the lamp brightness reference setting program stored in a bright environment brightness Lux _on, starts counting a period determined correction time ( S44); judging the count determination period, the new light ambient brightness value Lux _new continues to be less than the brightness ambient brightness value Lux _{on the} brightness reference adjustment program Lux _on (S45), and if so, then lowering the brightness reference adjustment program Calculate a new daytime brightness reference value day_level_new (S47), if not, then do not operate, and return to periodically detect the ambient brightness of the lamp body 10 after lighting and periodically obtain a new light environment brightness value Lux _new Step (S42).

The above correction procedure aims to recalculate a new daytime brightness reference value day_level_new, which can calculate the difference between the new light-brightness ambient brightness value Lux _new and the daytime brightness reference value day_level as a new brightness adjustment value ΔLux_new, The brightness adjustment value is multiplied by the multiple value K and added to the preset daytime brightness reference value day_level, instead of the new daytime brightness reference value day_level_new, that is, day_level_new=day_level+KΔLux_new, and due to the new brightness adjustment value ΔLux_new Since it is smaller than the brightness adjustment value ΔLux, the correction program can lower the new daytime brightness reference value day_level_new calculated by the brightness reference adjustment program.

Please refer to FIG. 9 further. The following is a further explanation of the response of the above-mentioned inductive luminaire in various situations. First, at dusk, the actual ambient brightness will begin to weaken. When the inductive luminaire measures the ambient brightness below the night brightness reference value night_level The brightness sensing module 21 will control the power output of the power module 22 to illuminate the lamp body 10. When the lamp body 10 is turned on, the brightness sensing module 21 starts to execute the brightness reference adjustment program. If the brightness of the environment is higher than the daytime brightness reference value day_level, the brightness sensing module 21 will increase the daytime brightness reference value day_level, and adjust the new daytime brightness reference value day_level_new as a point. The basis for extinguishing the lamp body 10, so bright When the degree sensing module 21 executes the click-off determination program, the lamp body 10 is not immediately turned off; after that, if the correction program measures the brightness of the new light, the ambient brightness is less than the brightness of the light environment measured by the brightness reference adjustment program (ie, maintains greater than 5 seconds), it means that the brightness sensing module 21 performs strong light interference in the brightness reference adjustment program, and the correction program will lower the new daytime brightness reference value day_level_new, and at this time, the brightness sensing module 21 is simultaneously executing the point-off determination program. When an instant glare is encountered (ie, the maintenance time is less than 15 seconds), the brightness sensing module 21 does not turn off the luminaire; when daylight, the actual ambient brightness will start to increase, but increase to exceed the new daytime brightness reference value. Day_level_new, and the maintenance time exceeds the daytime determination time value of 15 seconds, the brightness sensing module 21 determines that it is daytime, and controls the power module 22 to stop outputting power and clicks off the lamp body 10; thereby, in addition to avoiding lighting the lamp In addition to the situation that the brightness of the main body 10 is too high and the lighting is turned off, the brightness reference adjustment program can be further prevented from being overestimated due to short-term or instantaneous glare. Ambient light luminance value, suppressing misjudgment of short light function and the lamp off time point during the day to the body 10 again.

In summary, the brightness sensing module in the inductive lamp of the present invention has a built-in brightness reference adjustment program, so that it can automatically adjust the daytime brightness reference value after lighting, so as to avoid the light reflection due to the environment after lighting. The problem is that the inductive luminaire is repeatedly turned on and off, which avoids the trouble of use.
