AI Technical Summary

Benefits of technology

This patented technology improves the performance (efficiency), durability, safety, etc of an LED lamp used for illumination purposes by efficiently utilizing energy produced during operation without causing excessive temperatures or damage on other components within the system. By arranging the lasers around the fluorocalton instead of directly behind it, they act like lamps while still emiting their full brightness when turned off. Additionally, this design allows for quick cool down after use, increasing the lifespan of the materials involved. Overall, these technical improvements enhance the overall effectiveness and longevity of the LED lamp's functioning.

Problems solved by technology

The technical problem addressed in this patented technology relates to improving the performance and lifetimes of conventional red lasers excited from yellow phosphors due to their poor thermal characteristics caused by these compounds themselves during operation.

Abstract

In order to overcome the problem of incapability of timely dissipating accumulated heat efficiently due to continuous work of a fluorescent material in a traditional fluorescent illumination light source, the invention discloses a laser fluorescence excitation illumination device. The device consists of a laser light source, a reflecting bowl, a support mechanism and a fluorescence excitation device, wherein the fluorescence excitation device consists of a fluorescent turntable, a heat sink and a heat dissipating fin. The laser fluorescence excitation illumination device adopts an interval excitation mode, so that the fluorescent material is located in an intermittent working state to prevent centralized heat caused by continuous work and to improve the heat exchange efficiency. The fluorescent turntable and the heat sink are made of red copper materials with excellent heat conductivity; and heat generated by an excitation end can be quickly transferred to a back end heat dissipating structure. The back end heat dissipating structure is a of a fine structure for increasing the heat dissipating area. Heat conducting silicone grease is coated in each connected place in the device toprevent bad heat conduction caused by assembly gaps. The laser fluorescence excitation illumination device can effectively improve the heat dissipation efficiency of the fluorescent illumination device and prolong the service life of the fluorescent material.
