US 10,859,229 B1 · Light bar using surface-mount technology

Abstract

A light bar has a circuit board positioned within a housing and having light emitting diodes (LEDs) which are mounted to a surface of the circuit board with surface-mount technology (SMT). The housing has wiring electrically connected to a controller. The controller is configured to receive signals from the electrical system of the vehicle, interpret the signals received from the electrical system of the vehicle, and in response automatically control illumination of independently controllable LEDs. The controller is initially programmed to perform specific function(s) and/or strobe according to specific patterns and is thereafter at least partially restricted from being reprogrammed by a user to serve other function(s), either by restricting the emission of light in at least one color and/or preventing specific strobing pattern(s).

Dependent claims

A vehicle light bar comprising:

a circuit board positioned within a housing;
surface-mount device SMD assemblies, each SMD assembly comprising:
a white colored light emitting diode (LED);
at least three differently colored LEDs arranged:
(a) in-line;
(b) perpendicular to a longitudinal axis of the vehicle light bar;
and
(c) positioned below the white colored LED;
several resistors;
and
a capacitor;
wherein said SMD assemblies are mounted to a surface of the circuit board with surface-mount technology (SMT);
and
wherein the LEDs are capable of transmitting and varying an intensity of light in at least three different colors of an additive color model;
the housing having wiring electrically connected to a control box, said control box including logic for automatically and independently illuminating each of the LEDs and a processor, said processor programmed to control light emission according to one or more selected strobing patterns.
