Control Mechanism

Touch button A/B controls each light individually. Pushing the button→turn on the indicator light→subsequently turn on face light.

The colour temperature and brightness can be adjusted with the corresponding rotary dials. The adjustments, however, must be the same for both lights. The built-in memory chip stores the brightness level and the colour temperature settings during each use. User friendly→allows users to restore their last used settings.

Different set ups are available according to user preferences. By allowing users to adjust CCT and identifying warmer temperatures as the night mode, this can essentially help avoid disrupting circadian rhythms.

Considering the future possibilities for further adaptations, space is freed up for smart connectivity bridges (Wi-Fi/ Bluetooth). With simple modifications, this luminaire can be linked into the smart lighting network if needed.

Control Interface Mechanism

Each driver and CCT adjusting white controller are linked into the control interface and linked to a master switch mechanically with belt drives, allowing the CCT and illuminance of each light to be adjusted simultaneously. Having identical diameters allows the belt driven master dial mechanism below converts two analogue dials into one single dial mechanically. In a belt drive system, all three dials turn at the same angular, velocity, achieving the effect of dimming or switching colour temperature of both lights at the same time. The rotary dimmer and rotary controller (red square) are outside the luminaire frame for using. These four rotary dials are inside the luminaire.

Simulation in DIALUX

• CCT Adjustment

In the case of the same illuminance, adjust the colour temperature and observe the change of the spotlight in DIALux.

•The switch controls the adjustment of the color temperature, which can change the color temperature from warm to cool. By choosing the perfect CCT, users can more easily match it with traditional indoor lighting or natural lighting.

• Output Adjustment

The spotlight is turned on with different degrees of dimming from 25% to 100%.

Visual Effects

Under the condition of keeping the color temperature consistent, set the spotlight to any different dimmable levels as required.

•As the dimming level increases, the illuminance increases, and the shadow gradually deepens.

•When the user takes facial lighting as the main task, users can freely adjust the illuminance level by incorporating the actual lighting environment.

• Intensity measurement method

Using DIALux Evo, we have placed the luminaire on a desk, at the centre of a matte dark room (the reflectivity of the walls, floor and ceiling is set to 0). Having borrowed ldt files with similar properties from manufacturers such as Flos and Linealight, We set measurement points based on the light incident on a plane at a distance of 4 meters from the spotlight, and record the illuminance from 0 to 90 degrees (the light is symmetrical in the horizontal and vertical directions). Having marked the illuminance values every 5 degree, as well as eventually converting them to luminous intensity, we have essentially come up with an intensity distribution.

Both the spotlight and the tape light are turned on at the same time without any natural lighting or traditional indoor lighting.

•A horizontal light from the spotlight.

•The light emitted by a part of the strip light is perpendicular to the table.

•Higher illumination relative to the surrounding environment

The luminance intensity was calculated by distance and the illuminance collected from the measuring point in Dialux, , using the method demonstrated from the previous slide.
