JP3092249U - Detachable foot light using LED as light source - Google Patents

Abstract

(57) [Summary] (Modified) [PROBLEMS] The present invention is a footlight having a built-in LED, a small transformer, a resistor, and a diode for preventing reverse withstand voltage in an electric plug. The present invention relates to an LE integrated with an electric plug (1).
D3 is a light source and has a built-in small transformer 4, resistor 5, and diode 6 for preventing reverse withstand voltage to make it work. Lighting location can be freely selected and L
The power consumption is extremely small because the ED is used as the light source. It has an extremely long life and can be turned on all the time, so it is economical and can be operated with peace of mind at night. It works effectively in a disaster emergency because it can be installed in multiple places.

Description

[Detailed description of the invention]                 [0001]             [Technical field to which the invention belongs] The present invention is a detachable underfoot illumination lamp using an LED as an illumination light source.                 [0002]             [Prior art] Conventional footlights are fixed and set at predetermined positions in the building. Almost.                 [0003]             [Problems to be solved by the invention] There are few examples of footprints on the walls of ordinary houses, to wake up at night Do not fumble when searching for the power switch in the dark, or when returning to bed after turning off the light. Everybody experiences peace of mind, especially if they are elderly The complexity of searching for and blinking the power switch increases, and there is also a danger of falling over This is to prevent this from happening.                 [0004]             [Means for Solving the Problems] The present invention is installed in a normal electrical outlet installed in the lower part of the wall of a general house. By inserting the inserted general-purpose electrical plug, the LED inside the housing lights up and Because it is lit, it can be installed wherever lighting is required, making nighttime activities easier. You. This unit uses LED as the light source, so it consumes very little power, Because of this, it can be lit all the time without any trouble of blinking. A hood is attached to the light outlet to suppress the scattering of light I have.                 [0005]             [Embodiment of the invention] This unit is detachable with a general-purpose electrical plug, so you can select the location where you want lighting. If you want to use a vacuum cleaner during the day, disconnect the unit from the outlet, If you put it back after use, it will work again as a footlight. Does this unit use LED as a light source? It has a very long life and is free from the trouble of exchanging balls.                 [0006]             【Example】 The embodiment of the above-described invention is described in detail.                 [0007]             [Effect of the invention] Since the present invention is a detachable foot light using LED as a light source, it is installed on the wall of an old house. Just plug it in where you want it, using the electrical outlet Because it lights up inside, for example, multiple entrances, stairs, bedrooms, toilets, washrooms, etc. If it is installed, it will be easy for young and old to work in the dark, especially in fires and earthquakes. It is considered to be an effective source in any emergency.

Claims (1)

[Claim 1] An LED provided in one housing and an electric plug provided on a side surface of the housing to supply electricity to the LED. (2) An AC 100V power supply is guided from the electric plug to the input side of a small transformer provided in the housing, and is supplied with an AC voltage of 5V to 6.3V.
Reduce the output voltage to the extent. One terminal A of the three transformer output is led to a resistor provided in the housing, and the output is connected to one or more LEDs in series, and the output is connected to another terminal B of the transformer. 4. In order to prevent the LED from being destroyed due to the reverse withstand voltage, a destruction preventing transistor is connected between the output terminal of the resistor and the B terminal of the transformer. This is a detachable footlight that uses the LED having the above configuration as an illumination light source.
