Claims19
Indicating light for optical display, comprising a housing (1) with electrical lead parts (4), a light-emitting diode (12) arranged in a light rod (5) which has a translucent round head (9) the inner side (14) of which facing the light-emitting diode (12) has a refracting fine pearl structure.
Indicating light according to the preceding Claim, characterised in that at least the round head (9) of the light rod (5) has a milky tinge.
Indicating light according to one of the preceding claims, characterised in that at least the round head (9) of the light rod (5) is of a fluorescent milky colour.
Indicating light according to one of the preceding claims, characterised in that the light rod (5) is formed in one piece with the round head (9) and from the same material.
Indicating light according to one of the preceding claims, characterised in that the light rod (5) is formed as a cylindrical tube, one end of which is closed by the round head (9).
Indicating light according to one of the preceding claims, characterised in that the light rod (5) is fixed in the housing (1) by the tube end section (6) which is away from the round head (9).
Indicating light according to one of the preceding claims, characterised in that part of the light rod (5) in the housing (1) is cast over with moulding resin (8) according to the explosion protection requirements.
Indicating light according to one of the preceding claims, characterised in that the light rod (5) is designed as a pressure-resistant capsule for the purpose of way of explosion protection.
Indicating light according to one of the preceding claims, characterised in that the housing (1) is closed by a cover (2) into which the light rod (5) protrudes.
Indicating light according to one of the preceding claims, characterised in that a printed circuit board (10) with the light-emitting diode (12) and electronic components (13) arranged on it is provided within the light rod (5).
Indicating light according to one of the preceding claims, characterised in that the printed circuit board (10) is securely located in position between the holding ribs (11) in the light rod (5).
Indicating light according to one of the preceding claims, characterised in that a front casing (15) extends over the part of the light rod (5) which protrudes past the cover (2) of the housing (1).
Indicating light according to one of the preceding claims, characterised in that the front casing (15) has a translucent light cap (17) extending over the round head (9) of the light rod (5).
Indicating light according to one of the preceding claims, characterised in that the inner side (23) of the light cap (17) facing the round head (9) of the light rod (5) has a refracting fine pearl structure.
Indicating light according to one of the preceding claims, characterised in that the fine pearl structure of the inner side (14) of the light rod (5) and the fine pearl structure of the inner side (23) of the light cap (17) are essentially identical.
Indicating light according to one of the preceding claims, characterised in that the light cap (17) has a milky or milky/coloured fluorescent tint.
Indicating light according to one of the preceding claims, characterised in that the round head (9) of the light rod (5) and the light cap (17) are tinted to suit the wavelength of the light colour of the light-emitting diode (12).
Indicating light according to one of the preceding claims, characterised in that the light cap (17) is held by a front ring (18) which can be attached at an insert housing (16).
Indicating light according to one of the preceding claims, characterised in that the front casing (15) is attachable to the mounting wall (21) which is arranged between the front ring (18) and a threaded nut (22) located at the insert housing (16).
