摘要:
The invention relates to a low-pressure gas discharge lamp which includes at least one discharge vessel and at least two capacitive coupling-in structures and operates at an operating frequency f. In order to achieve a better efficiency in combination with a small structural volume, a high luminous flux, a low operating voltage, a low electromagnetic emission, a high resistance against switching transients and a long service life for the low-pressure gas discharge lamp, it is proposed to form each capacitive coupling-in structure from at least one dielectric having a thickness d and a dielectric constant ∈, each dielectric being subject to the condition d/(f.∈)

The present invention relates to a lamp unit (501) for an adaptive front lighting system (AFS) (500) for a vehicle (100). The lamp unit (501) comprises a liquid crystal element (200/200′) arranged to receive light emitted by a light source (502), which liquid crystal element (200/200′) has a first state in which it is adapted to transmit incoming light without substantially refracting said incoming light, and a second state in which it is adapted to refract said incoming light when the light passes through said liquid crystal element. This allows light to be altered without any mechanical movements in or of the lamp unit (501). The present invention also relates to an AFS (500) comprising such a lamp unit (501), and a vehicle (100) comprising such an AFS (500).

The invention relates to a light source (1) with a discharge vessel (12) which is filled with a filling gas, and with an electron beam source (2) which is arranged in vacuum or in a region of low pressure and which generates electrons, propelling the latter through an entry foil (10) into the discharge vessel (12). According to the invention, an electric field can be generated inside the discharge vessel (12).
摘要:
In a capacitively coupled discharge lamp the electrode comprises a dielectric material that during operation is in contact with the discharge. The impedance of the dielectric material is small and its electron affinity is negative. In this way it is realized that the discharge lamp can be operated efficiently at low frequencies (less than 500 KHz).

A security system is described, comprising a sensor module (15) which accommodates a laser sensor (10) working with self-mixing interference. The laser sensor (10) generates measurement data which are related to the velocity of an object such as the body of a human being and, optionally, the distance between the laser sensor (10) and the object. Dependent on the measurement data assembled by the laser sensor (10) and supplied to a control circuit (30) such as an airbag computer, the airbag computer activate security means such as an airbag (35)in order to prevent injuries of the human body. Furthermore, a method of driving such a security system is described.
