Abstract

Audio landscape/pathway lights, devices, apparatus, systems and methods using BLUETOOTH wireless communication technology with integrated speakers, receivers/transmitters, outdoor speaker, PCB control card, driver, amplifier and FM receivers/transmitters. A single primary unit, which can be a pathway (landscape) light, can have a BLUETOOTH receiver and an FM transmitter, a speaker and a light (LED) and LED control. Secondary units can each contain a pathway/landscape light and FM receivers and speaker, and LED control. A Bluetooth enabled device from a portable digital device can send BLUETOOTH audio signals to the primary unit which automatically relays the audio signal to the secondary units so that the audio signal (music, words, and the like) can be synchronized and played simultaneously at all the units without lag time, echoes or reverberation, and without any other undesirable noise effects.

Claims

1. An outdoor BLUETOOTH pathway/landscape lighting system, consisting of:

a primary unit with a light and BLUETOOTH receiver which receives audio signals from a BLUETOOTH enabled device, and a transmitter, and a primary speaker, the primary unit having a primary housing consisting of three tier covers on top of a primary ground based stake; and

at least one secondary unit having a secondary ground mounted light and receiver that receives audio signals from the primary transmitter, and a speaker, each secondary unit having a secondary housing consisting of three tier covers on top of a secondary ground based stake, wherein the receiver on the primary unit receives the audio signal from the BLUETOOTH enabled device and relays the audio signal by the transmitter to each receiver on each secondary unit, so that the primary speaker and each secondary speaker plays the audio signals simultaneously with no lag time between playing the audio signals between each of the primary and secondary units when used outdoors; and

the primary housing and the secondary housing, each consists of a top tier cover for mounting the speaker a middle tier cover for mounting a lens and a bottom tier cover for mounting the light and a heat sink, wherein the transmitter and the receiver include an FM (frequency modulated) transmitter and FM (frequency modulated) receiver, that each have an FM frequency range consisting of between 76.5 Mhz to 83.2 Mhz, and consisting of automatic switching to 4 channels in the FM frequency range.

2. The system of claim 1, wherein each bottom tier includes an LED (light emitting diode) mounted on a cylindrical shaped heat sink.

3. The system of claim 1, wherein the primary unit and each secondary unit include:

a support mount for mounting each speaker to direct the audio signals in a downward direction, therefrom.

4. The system of claim 1, wherein the primary unit and each secondary unit include:

a micro controller chip for allowing each speaker to generate the audio signals simultaneously from the primary unit and each secondary unit.

5. A method of simultaneously playing audio signals from landscape and pathway lights mounted outdoors, consisting the steps of:

providing a primary unit having a primary light and a protocol receiver which receives audio signals from a remote protocol BLUETOOTH enabled device, and a transmitter, and a primary speaker;

providing at least one secondary unit, each having a secondary light, a receiver and a secondary speaker;

providing the primary unit and each secondary unit to each have a housing consisting of three tiers with a ground based stake extending below the housing;

providing the primary unit and the at least one secondary unit each consist of a top tier cover for mounting the primary and the secondary speaker a middle tier cover for mounting a lens and a bottom tier cover for mounting the primary and the secondary light and a heat sink;

sending a protocol generated audio signal to the protocol receiver in the primary unit and transmitting the audio signal from the transmitter to each receiver in each secondary unit;

synchronizing each speaker in the primary unit and each secondary unit to play the audio signal simultaneously with no lag time between playing the audio signals between each different unit when used outdoors;

transmitting the audio signal through a FM (frequency modulated) channel from an FM (frequency modulated) transmitter at the primary unit;

receiving the audio signal with an FM (frequency modulated) receiver at each secondary unit; and

providing the FM (frequency modulated) transmitter and the FM (frequency modulated) receiver, each have a FM frequency range consisting between 76.5 Mhz to 83.2 Mhz, and consisting of automatic switching to 4 channels in the FM frequency range.

6. The method of claim 5, wherein the step of synchronizing includes the step of:

providing a micro processor controller chip at the primary unit and each secondary unit.

7. The method of claim 5, wherein each bottom tier cover includes a mount for mounting an LED (light emitting diode) on a cylindrical heat sink.

8. A pathway and landscape lighting and audio generating system for use outdoors, consisting of:

a primary unit having a protocol receiver which receives audio signals from a remote protocol enabled BLUETOOTH device, with a transmitter and primary speaker, and primary light, the primary unit having a primary housing consisting of three tiers with a primary ground based stake extending below the primary housing; and

at least one secondary unit having a receiver that receives audio signals from the primary transmitter, and secondary speaker, and secondary light, each secondary unit having a secondary housing consisting of three tiers with a secondary ground based stake extending below the secondary housing;

the primary housing and the at least one secondary housing, each consisting of a top tier cover for mounting the primary and the secondary speaker a middle tier cover for mounting a lens and a bottom tier cover for mounting the primary and the secondary light and a heat sink;

a single low voltage power supply for supplying a single low voltage power to the primary unit and each secondary unit, wherein the protocol receiver on the primary unit receives the audio signal from the remote protocol enabled BLUETOOTH device and relays the audio signal by the transmitter to each receiver in each secondary unit, so that the primary speaker at the primary unit, and the secondary speaker at each of the secondary units generates the audio signals simultaneously without lag time between playing the audio signals when used outdoors, wherein the primary unit transmitter is an FM (frequency modulated) transmitter that sends the audio signals over an FM channel to an FM (frequency modulated) receiver, wherein the FM (frequency modulated) transmitter and the frequency modulated receiver, each have an FM frequency range consisting of between 76.5 Mhz to 83.2 Mhz, and consisting of automatic switching to 4 channels in the FM frequency range.

9. The system of claim 8, wherein each bottom tier cover includes a mount for mounting an LED (light emitting diode) on a cylindrical heat sink.
