Title: Directional control method for led lamp and optical space transmission device
Inventor: MURAYAMA MASAHIKO
IPC: G09F13/20
Filed: 1993-04-15
Abstract: PURPOSE:To increase the relatively large quantity of the emitted light over the entire part and to easily and rapidly change over directivity in a desired direction by adequately changing the balance of the driving currents to be passed to respective LED chips and changing the directivity of the light emitted from LED lamps. CONSTITUTION:The LED lamps are controlled in driving by an LED driving circuit 20 and the respective LED chips 14, 15 emit light. The control signals inputted from an input terminal 27 of this LED driving circuit 20 are amplified by an amplifier 26 and are then sorted in accordance with the resistance values between the moving contact 25a of a variable resistor 25 and the terminals at both ends to control respective transistors 23, 24. The LED chips 14, 15 are thus controlled in driving by the inputted control signals. The directivity of the LED lamps is changed by the simple operation of merely involving the movement of the moving contact 25a of the variable resistor 25.

IPC: G01N21/53
Filed: 1982-05-28
Abstract: PURPOSE:To measure precisely front minute angle scattered light intensity whose scattering angle is between 0.5 degree and about 5 degrees, by eliminating an incident primary lumnous flux which becomes a generating source of the maximum optical noise, without reflecting it to the incident side. CONSTITUTION:Scattered light separated in accordance with a scattering angle is inputted as intensity around the solid angle of its opening, by an optical fiber 6a placed in the image plane, and is detected by a photocell detector 5. Also, minute angle scattered light 10 is separated from a primary luminous flux 11 by selecting suitably a curvature of a small convex face total reflector 7, and is detected by an optical fiber 6b and the detector 5. Intensity of said minute angle scatered light 10 is corrected after detection by considering a reflection factor of a mirror 7 and a detected solid angle. The primary luminous flux which is not detected by that time, and scattered light of a more minute angle are eliminated by a light trap 9 through a lens barrel 8 having a total reflection face on the inside face.
