Claim Rejections - 35 USC § 102
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claims 1-15 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by U.S. Patent Publication No. 2017/0202071 (“Chen”).
Regarding Claim 1, Chen discloses a method for temperature compensation (Figs. 5 and 7-9; [0006]-[0022]; [0159]-[0201]), the method comprising:
receiving a target color point for light emitted by at least one light-emitting device (3,4 in Fig. 5; [0117]-[0121]);
determining an operating electrical energy of the at least one light-emitting device based on a correlation of at least one temperature value of the at least one light-emitting device with the received target-color point (using controller 5 in Fig. 5; [0115]); and
operating the at least one light-emitting device based on the determined operating electrical energy (5 in Fig. 5; [0115]).
Regarding Claim 2, Chen further discloses wherein the target color point comprises a Tristimulus value for the light emitted by the at least one light-emitting device ([0203]-[0206]).
Regarding Claim 3, Chen further discloses wherein the at least one temperature value is occurring locally at the at least one light-emitting device (junction temperature, [0042]; [0095]; [0123]; [0126]).
Regarding Claim 4, Chen further discloses wherein the determining further comprises: determining a contribution of each of the at least one light-emitting device to the received target color point (using controller 5 in Fig. 5; [0115]; 3, 4; [0117]-[0121]).
Regarding Claim 5, Chen further discloses wherein the contribution depends on a respective peak electrical energy with which each of the respective light-emitting devices is operated ([0209]).
Regarding Claim 6, Chen further discloses wherein the contribution depends on the at least one temperature value of each of the respective light-emitting devices ([0209]).
Regarding Claim 7, Chen further discloses storing the contribution as a function of temperature values of each of the respective light-emitting devices in a look-up table, wherein the look-up table is used for determining the operating electrical energy of each of the at least one light-emitting devices (lock-up table used by controller 5 in Fig. 5; [0115]).
Regarding Claim 8, Chen further discloses storing the contribution at a standard temperature of each of the respective light-emitting devices in a vector, wherein the vector is used for determining the operating electrical energy of each of the at least one light-emitting devices ([0168]-[0181]).
Regarding Claim 9, Chen further discloses modelling the temperature dependency of the contribution by applying a respective relative deviation to the stored contribution at the standard temperature ([0168]-[0181]).
Regarding Claim 10, Chen further discloses wherein the standard temperature is 25°C ([0168]-[0181]).
Regarding Claim 11, Chen further discloses wherein each relative deviation depends on the at least one temperature value of the respective light-emitting device ([0200]).
Regarding Claim 12, Chen further discloses wherein the correlation is constituted by a linear system of equations ([0168]-[0181]; [0194]).
Regarding Claim 13, Chen further discloses wherein the received target color point comprises a brightness of the light emitted by the at least one light-emitting device ([0008]; [0117]-[0121]).
Regarding Claim 14, Chen further discloses wherein the at least one light-emitting device comprises at least of a red light-emitting diode, LED, a green light-emitting diode, LED, and a blue light-emitting diode, LED (RGB LEDs; [0205]).
Regarding Claim 15, Chen discloses an apparatus for temperature compensation of at least one light-emitting device (Figs. 5 and 7-9; [0006]-[0022]; [0159]-[0201]), the apparatus comprising:
a receiving unit for receiving a target color point for light emitted by the at least one light-emitting device (3, 4 in Fig. 5; [017]-[0121]);
a determination unit for determining an operating electrical energy of the at least one light-emitting device based on a correlation of at least one temperature value of the at least one light-emitting device with the received target color point (using controller 5 in Fig. 5; [0115]); and
an operating unit for operating the at least one light-emitting device based on the determined operating electrical energy (5 in Fig. 5; [0115]).
Conclusion
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
U.S. Patent No. 6,441,558 (“Muthu”) relates to a white LED luminary light control system.
