LBTEK offers LED Point Light Sources and Constant Current Controllers. The LED point light sources feature high brightness, small luminous area, low power consumption, and long service life, with a compact and small form factor. Two color temperature options are available: 5700-6500 K and 6500-7000 K. Among them, the LB-L21-64-WDG model adopts a special focusing design, providing higher illuminance than standard point light sources, with uniformity ≥95%. LED point light sources are commonly used for coaxial illumination of lenses and surface defect inspection of flat objects. When in use, they must be paired with the LBTEK constant current controller LB-CL0503B-4T.

LBTEK Constant Current Controller features four-channel output with an output voltage of 5V and a total power of 30W, capable of simultaneously powering four LED point light sources. The output ports automatically detect load current to prevent damage to the light sources. Its control panel consists of light source interfaces, indicator lights, digital tubes, buttons, serial port interfaces, trigger ports, and an AC socket with a switch. The CH button is used to switch channels, displayed on the first digit of the digital tube—when "H1" is displayed, it indicates constant-on mode, while "H0" indicates constant-off mode. The ▲ button increases brightness, and the ▼ button decreases brightness, with the brightness level displayed on digits 2-4 of the digital tube. The female serial port is used for RS232 communication with a PC. The external trigger port accepts DC 5-24V trigger signals to synchronize light source output. For detailed wiring and operation of external triggering, please refer to the manual.

The LBTEK LED Point Light Source Adapter can be used to mount LED point light sources, connecting them to optomechanical components such as adjustment mounts with SM1 tapped holes or coaxial systems. The clamped component is securely installed via the side M3 rubber-tipped set screw, preventing rotation and slippage to ensure alignment between the center of the clamped component and the optical axis. The M3 rubber-tipped set screw can be adjusted and tightened using a 1.5 mm hex key.
