Technical Description

Camera head lamp with integrated wireless signal receiver, and weighing only 350 grams.

This completely novel head light design contains a bi-color light with color temperatures of 3,200 and 5,400 Kelvin. At 5,400 K it achieves a brightness of 1000 Lux / 1m, while at 3,200 K the brightness is 700 Lux / 1m.

The light density is kept relatively low through the use of a 70mm x 140mm light panel. The wide lighting angle and the optionally insertable diffusion gel permit achieving a very even lighting.

If a manual adjustment of the brightness should be necessary, the light can be switched to a manual mode and the brightness can be adjusted via two integrated controllers.

The nonlinear control curve of the LED is linearized inside the lamp and mimics the characteristics of a conventional incandescent light. Internally, the lamp is working with ca. 4000 brightness levels – as a result, it permits changes in the brightness while in „ON“ mode, without any noticable jumps in brightness during the adjustment.

A DMX-Controller decodes the control signal that is sent to the lamp via the transmitter. A controller can be connected with up to 4 different lamps, which can then be controlled independently of each other through a total of 8 DMX channels.

Every lamp uses the data from two DMX channels to adjust each of the two color temperatures independently from 0-100%. This way, the light designer has complete control over both brightness and color temperature.

The DMX starting adress is set at the controller.

The wireless signal transmission uses frequencies in the 2,4 GHz range, which are also used by WLAN technology – however, it is not in fact using WLAN technology.

Through the ability to switch frequencies and the creation of groups within a frequency, several systems can be operated in parallel.

Power is supplied through an attachable power cable with a voltage of 12-24 volts. The required current at maximal usage of both color temperatures is about 1200 mA. To make it easier to set up the device, the received DMX data, signal reception strength and the supply voltage of the lamp are shown on the controller. Moreover, the status of the lamp (manual / remote) is shown in the controller display.  Through the use of a test button, the lamp can be reached via wireless signal even without the presence of a DMX signal. A valid DMX signal is also indicated in the controller display.
