Patent ID: 7414370

Claim:
A lamp comprising: a transistor having a control terminal, said transistor passing a current of a magnitude determined by a voltage at said control terminal; a LED array coupled to said transistor, and generating light with an intensity proportionate to said magnitude of said current; and a driver block coupled to said control terminal, wherein said driver block comprises at least one component having a cross voltage which has a negative correlation with said operating temperature, wherein said voltage is derived across said component to generate said voltage with a first level in response to an operating temperature of said lamp being equal to a first value, and with a second level in response to said operating temperature of said lamp being equal to a second value, wherein said first value is not equal to said second value and said first level is not equal to said second level such that said LED array generates light with a different intensity in response to said operating temperature of said lamp being at said first value compared to when said operating temperature of said lamp being at said second value wherein said first value is more than said second value, and said first level causes said magnitude to be lesser compared to the magnitude caused by said second level, whereby LEDs in said LED array pass less current in response to an increase in said operating temperature.
