Lens-fitted retrofit LED lamp system
View Patent ↗The disclosure describes systems and methods for retrofitting a light fixture using a lens-fitted retrofit assembly. The lens-fitted retrofit assembly is attached anterior to the LED lamp engine. A lens-fitted retaining adapter of the lens-fitted retrofit assembly includes at least one curved portion that matches a radius of curvature of a lens holder of the light fixture. The lens-fitted retrofit assembly is held into the light fixture based at least in part on the lens-fitted retaining adapter and the lens holder.
1. An LED lamp system that retrofits into a light fixture, comprising:
an LED lamp engine;
a lens-fitted retrofit assembly attached anterior to the LED lamp engine; and
a lens-fitted retaining adapter of the lens-fitted retrofit assembly, the lens-fitted retaining adapter comprising an anterior-facing protrusion comprising a notch that secures the lens-fitted retaining adapter aligned in place relative to a lens holding clip of a lens holder of the light fixture, and
wherein the LED lamp system is held into the light fixture based at least in part on the lens-fitted retaining adapter and the lens holder.
2. The LED lamp system of claim 1 , wherein the lens holder comprises a lens-shaped recess.
3. The LED lamp system of claim 1 , wherein the lens-fitted retrofit assembly further comprises an accessory retainer.
4. The LED lamp system of claim 3 , wherein the accessory retainer comprises a magnetic or ferromagnetic metal backplate that magnetically holds a magnetic or ferromagnetic metal front-plate.
5. The LED lamp system of claim 3 , wherein the accessory retainer holds at least one of: a lens, a light-shaping diffusion film, a holographic diffusion film, and a color filter.
6. The LED lamp system of claim 3 , wherein the accessory retainer attaches anterior to the lens-fitted retaining adapter.
7. The LED lamp system of claim 1 , further comprising a base socket adapter that electrically connects the LED lamp engine to an electrical power output of the light fixture.
8. An LED lamp system that retrofits into a PAR lighting fixture, comprising:
an LED lamp engine comprising at least one LED light source;
a lens-fitted retaining adapter that secures the LED lamp engine to a lens holder of the PAR lighting fixture, wherein the lens-fitted retaining adapter comprises an anterior-facing protrusion that forms a notch that secures the lens-fitted retaining adapter aligned in place relative to a lens holding element of the lens holder;
a total internal reflection (TIR) lens assembly attached anterior to the lens-fitted retaining adapter; and
an accessory retainer anterior to the TIR lens assembly.
9. The LED lamp system of claim 8 , wherein the TIR lens assembly comprises a TIR lens and a connecting component that connects the TIR lens to the lens-fitted retaining adapter.
10. The LED lamp system of claim 8 , wherein the accessory retainer comprises a magnetic accessory retainer that magnetically holds an accessory of the LED lamp system between the magnetic accessory retainer and the TIR lens assembly.
11. The LED lamp system of claim 8 , wherein the accessory retainer comprises a spring accessory retainer that holds an accessory of the LED lamp system to the TIR lens assembly.
12. The LED lamp system of claim 8 , wherein the accessory retainer holds an accessory comprising at least one of: a color filter, a beam shaping film, a diffusion film, and a holographic diffuser film.
13. The LED lamp system of claim 8 , wherein the notch of the protrusion of the lens-fitted retaining adapter secures the LED lamp engine to a spring locking lens retainer clip comprising the lens holding element of the lens holder of the PAR lighting fixture.
14. The LED lamp system of claim 8 , further comprising:
a lamp socket adapter that electrically connects the LED lamp engine to an original lamp socket of the PAR lighting fixture.
15. The LED lamp system of claim 8 , further comprising:
a custom lamp cap that connects to a posterior of the PAR lighting fixture in place of an original lamp cap of the PAR lighting fixture, the custom lamp cap comprising a lamp socket that differs from an original lamp socket of the original lamp cap; and
a lamp socket adapter that electrically connects the LED lamp engine to the custom lamp cap.
16. A method for retrofitting a light fixture, the method comprising:
removing a lens from a lens holder of the light fixture;
attaching an LED engine to a lens-fitted retrofit assembly;
attaching the lens-fitted retrofit assembly to the light fixture by inserting the lens-fitted retrofit assembly into the lens holder, the lens-fitted retrofit assembly comprising a lens-fitted retaining adapter comprising anterior-facing rotation stops that secure the lens-fitted retaining adapter in place relative to a lens holding element of the lens holder; and
electrically connecting the LED engine to a lamp base of a back cap that is coupled to the light fixture, the LED engine being connected to the lamp base using a lamp base adapter comprising a lamp base connector that matches the lamp base and an LED engine connector that matches an electrical connection of the LED engine.
17. The method of claim 16 , further comprising:
removing a light source from the back cap, wherein the back cap is an original back cap of the light fixture.
18. The method of claim 16 , further comprising:
replacing an original back cap of the light fixture with the back cap, wherein the back cap is a custom back cap that connects to a posterior of the light fixture in place of an original lamp cap of the light fixture, the custom back cap comprising a lamp socket that differs from an original lamp socket of the original back cap.
19. The method of claim 16 , wherein the lens-fitted retrofit assembly further comprises an accessory retainer.
20. The method of claim 19 , further comprising:
holding an accessory using the accessory retainer, the accessory comprising at least one of: a color filter, a beam shaping film, a diffusion film, and a holographic diffuser film.
