Description

[Detailed description of the invention] This invention relates to an LED indicator light in which the holding part for attaching the LED is made of a synthetic resin with high reflectance, and a reflective concave surface is integrally formed on the front surface.

Conventionally, the brightness of a single LED indicator light was weak, making it extremely difficult to illuminate a large area. or,
Since the LED lead legs are soldered directly to the cap, the caps are not interchangeable and the soldering work is extremely difficult.

This idea provides a reflective recess integrally on the front surface of the holding part where the LED is attached, and allows multiple LEDs to be attached depending on the desired amount of illumination.
By using multiple LED mounting holes and a printed circuit board in advance, it is possible to
The LED can be used freely, and the reflective concave surface allows the LED illumination to be used without wasting it.

An example of this invention will be explained with reference to the drawings.1
is a holding part made by injection molding using a synthetic resin with good reflectance (for example, ACS resin), and has a concave surface 2 that functions as a reflector on the front surface, and a concave surface 2 on the bottom of this concave surface.
A plurality of small holes 3, 3 for mounting the LED are passed through. 4 is a nut embedded and fixed in the center of the lower surface of this holding part. Reference numeral 6 denotes a printed circuit board that comes into contact with the lower surface of the holding part 1, and is printed so that the lead legs of the maximum number (four in this example) of LEDs 5 to be installed in the concave surface 2 can be connected. When two pieces are attached, they can be connected to either one of the prints on the printed circuit board 6. In addition, when the lead legs of the LED were soldered directly to the base as in the past, the work was difficult and the reliability was low, but in the present application, the lead legs are soldered to the printed circuit board, thereby further improving reliability. I can do it.
Furthermore, since the base 10 of the same standard as the incandescent bulb 20 is used for contact with the power source side of the LED, it can be attached anywhere an incandescent bulb can be attached.

Next, in order to fix the cap 10 to the holding part 1, an insulating bush 12 is installed in the hole 11 made in the center of the bottom of the cap 10, and a set screw with a hexagonal head is installed in the center of the insulating bush 12. 13 is inserted into the hole drilled in the printed circuit board 6, and screwed into the nut 4, and the cap 10 in contact with the printed circuit board 6 is tightened to the nut 4.
serves as one electrode, and a set screw 13 connected to the printed circuit board 6 serves as the other electrode. Compatibility is achieved by making the base 10 removable.

As mentioned above, this idea has a reflective concave surface on the front surface of the holding part by integrally molding it with synthetic resin.
The LED light can be used without wasting it, and since the concave surface 2 is made of highly reflective resin, there is no need for coating or other work, making it extremely efficient to assemble, and it is the same as an incandescent bulb. Because it uses a standard cap, it works just like a traditional incandescent bulb.
It is possible to use LED lamps.
