Abstract

A lamp structure has a slim light emitting source including at least one LED packaged on a multilayered printed circuit board type aluminum base. A funnel-shaped reflector is concaved toward a center thereof and defined with at least one hole for partially accommodating the LED. An inner surface of the reflector is coated to form a light reflecting surface. A flat lens includes a surface being treated with sand blast. A lamp housing has a receiving chamber for accommodation of the slim light emitting source, the reflector, the flat lens, and a driver. The lamp housing is formed with a plurality of heat dissipation fins. The driver is inserted in the other end of the receiving chamber of the lamp housing and has positive and negative leads connected to the slim light emitting source for enabling it to produce light.

Claims

1. A lamp structure comprising:

a slim light emitting source including at least one light emitting diode packaged on a multilayered printed circuit board type aluminum base;

a funnel-shaped reflector being concaved toward a center thereof, and in a bottom of the funnel-shaped reflector being defined at least one hole for partially accommodating a surface of the slim light emitting diode, with an inner surface of the funnel-shaped reflector being coated to form a light reflecting surface;

a flat lens whose surface is treated with sand blast; and

a lamp housing including a receiving chamber, one end of the receiving chamber being accommodated with the slim light emitting source, the funnel-shaped reflector, and the flat lens, respectively, and the other end of the receiving chamber being provided for insertion of a driver, with an outer surface of the lamp housing being formed with a plurality of heat dissipation fins, with the driver being inserted in the other end of the receiving chamber of the lamp housing and having positive and negative leads connected to the slim light emitting source for enabling the slim light emitting source to produce light, wherein the aluminum base is provided around a periphery thereof with two oppositely arranged locking grooves for passage and electrical connection of the positive and negative leads and with a plurality of gaps for taking out the slim light emitting source from the lamp housing when replacement is required.

2. The lamp structure as claimed in claim 1, wherein the slim light emitting diode is any color.

3. The lamp structure as claimed in claim 1, wherein the slim light emitting diode is high power.
