Definitions
- FIG. 5 shows an example of a conventional LED lamp in a sectional view (see, for example, Patent Document 1).
- the LED lamp X shown in the figure includes a long rectangular substrate 91, a plurality of LEDs 92 mounted on the substrate 91, a tube 93 that accommodates the substrate 91, and a terminal 94.
- a wiring pattern (not shown) connected to the plurality of LEDs 92 and the terminals 94 is formed on the substrate 91.
- This LED lamp X is configured such that a plurality of LEDs 92 can emit light by fitting a terminal 94 into an insertion port of a socket of a general fluorescent lamp lighting fixture.
- the pipe diffuses and transmits light from the plurality of LED modules.
- the substrate 10 is made of, for example, Al and includes a plurality of heat sinks 11 and is formed in an annular shape in plan view.
- a wiring pattern (not shown) is formed on the surface of the substrate 10.
- the plurality of heat sinks 11 protrude from the back surface of the substrate 10, are parallel to each other, and are arranged along the radial direction of the substrate 10.
- the LED lamp according to the present invention is not limited to the above-described embodiment.
- the specific configuration of each part of the LED lamp according to the present invention can be varied in design in various ways.
- the substrate and the heat sink may be separated into different members. Further, a part of the pipe may be opened.
- the pipe referred to in the present invention is not limited to the one that diffuses the light from the LED module, and may be one that transmits the light from the LED module without diffusing.
