Abstract

The present invention provides a lamp, comprising a lamp shell, which comprises a base configured to connect an external power supply and a heat dissipation module coupled to the base, wherein an interior chamber is defined within the lamp shell; a light source; and a driver module coupled to the light source, with at least part of the driver module located within the interior chamber, the driver module is configured to regulate current provided to the light source. The lamp shell comprises a mounting module configured to receive a mounting part of the driver module to fasten the driver module to the lamp shell, the driver module and the heat dissipation module of the lamp shell are electrically connected.

First claim

The invention claimed is:

1. A lamp, comprising:
a lamp shell comprising an interior chamber defined within the lamp shell, a heat dissipation module defined by an outer surface of the lamp shell, and a base coupled to the heat dissipation module, the base configured to connect an external power supply to the heat dissipation module;
a light source; and
a driver module (i) having a top end coupled to the light source and a bottom end coupled to the base (ii) being at least partially disposed within the interior chamber, and (iii) configured to regulate current provided to the light source;
wherein the heat dissipation module comprises a mounting module having at least two mounting slots configured to receive a mounting portion of the driver module, the driver module comprising a spring having one end being coupled to the heat dissipation module via a portion of the interior chamber of the lamp shell located above the base and a second end coupled to the top end of the driver module; and
wherein the receiving of the mounting portion of the driver into the mounting slots and the coupling of the spring to the heat dissipation module fastens the driver module to the lamp shell, the fastening facilitating an electrical connection between the driver module and the heat dissipation module of the lamp shell.

2. The lamp according to claim 1 , wherein one end of the driver module is coated with solder and is interference fitting with the mounting slots to achieve the electrical connection between the driver module and the heat dissipation module.

3. The lamp according to claim 1 , wherein the driver module comprises a spring coupled to a boss of the heat dissipation module, for electrically connecting the driver module to the heat dissipation module.

4. The lamp according to claim 1 , wherein the base comprises a cap and a pin module mounted on the cap, and the pin module comprises an insulating support plate and at least one pin, wherein the at least one pin is electrically connected to the external power supply.

5. The lamp according to claim 4 , wherein the cap and the heat dissipation module are integrally formed.

6. The lamp according to claim 1 , wherein the base comprises an insulating portion and a thread portion extending outward from at least a part of an outer surface of the insulating portion, the thread portion configured to connect with the external power supply, the insulating portion coupled to the heat dissipation module.

7. The lamp according to claim 1 , wherein the heat dissipation module is made of a thermal conductive material that provides EMI shielding, and wherein the lamp shell further comprises an insulating shell covering at least a part of an outer surface of the heat dissipation module, the insulating shell made of a material selected from poly (vinyl chloride) alloy, polycarbonate, polymethyl methacrylate, polyvinyl chloride, polystyrene, polyethylene and combinations thereof.

8. The lamp according to claim 1 , wherein the lamp comprises a reflector-type lamp, and the light source comprises at least one of a light emitting diode light source and a gas-discharge light source.

9. The lamp according to claim 1 , wherein the driver module comprises a power ground end electrically connected to the heat dissipation module.

10. The lamp according to claim 9 , further comprising a capacitance coupled between the power ground end and the heat dissipation module.

11. The lamp according to claim 1 , further comprising a lens coupled to the lamp shell, wherein the interior chamber is defined between the lens and the lamp shell.
