The object of the invention is to provide a plug-in module System for constructing different plug-in module circuit boards from couplable plug-in modules for light-emitting diodes which are to be plugged onto the circuit board top side for example. The plug-in modules can be connected to the housing outer sides for forming the circuit boards from longitudinal circuit board rows by means of lateral longitudinal recesses and grid ribs, wherein, in each case one upper guide bore with an electrical voltage contact-making means, for example for a common plug-in diode bridge, is applied to the top sides of two adjacent plug-in modules in a laterally adjacent manner, and for forming additional perpendicular circuit board rows in each case contact-making means and plug-in connections of the contacts of the circuit board longitudinal rows on the front side with a projecting end section of a contact spring strip with corresponding contact-making means of the plug-in modules of the perpendicular circuit board rows, further on their housing rear sides an opening housing outlet with openings of the guide bores for mating the contact spring strips with the contact spring end section of the rear plug-in module. The plug modules therefore have two guide bores with a contact spring strip which widens from the top side to the front side over two contacts, a common wide front opening of the guide bores and a latching structure on the outer sides. Furthermore, latching and plug-in sections for contact spring strips which are situated one behind the other on the housing rear sides when mating in perpendicular longitudinal circuit board rows as conductor strips for voltage connection.

The rail structure includes a rail; the rail includes a body and a light outgoing area formed by the body; the body further defines an opening position in communication with the light outgoing area, and the opening position is located at a light emitting direction of the light outgoing area; the body has an extending end located at the opening position, and the extending end is configured to fix a light guide plate; the body defines a light source mounting position, the light source mounting position is adjacent to the light outgoing area, and is configured to mount a light source.

An adaptor for manually converting a conventional portable lamp with a harp supported shade from (a) a single Edison up-socket adapted to receive an Edison-based, base-down, incandescent, compact florescent or LED light bulb to (b) a plural down-socket LED lighting system with materially increased task lighting, where the rapid conversion does not require the use of tools or any special skills, does not require any modification of the wiring of the conventional lamp, and does not change the aesthetics of the lamp. Methods of making the conversion are disclosed that do and do not require the removal of the harp during the conversion.

The Multiple functions LED nigh light not only offer LED even brightness or indicator light illumination under predetermined colors, functions, effects by multiple time reflection and refraction of light beam travel within or between the at least one of 1.sup.st optics-lens, 2.sup.nd optics-lens, inner wall of night light to eliminate the spot-light and get even brightness shown on whole 2.sup.nd optics-lens and front lens with built-in texture or opaque or optics treatments. Night light has at least one of LEDs within to create at least one of preferred light effects for color-changing, color selection, functions selection and the night light has even brightness shown on the front lens or 2.sup.nd optics-lens or indicator illumination also has at least one of preferred addition function(s) select from switch, sensor, PIR sensor, radar sensor, rechargeable battery, power fail light, USB charging or be-charged port(s) or system, outlets, audio device, surge/over heat/over charge/short-circuit protection, function selection between motion or non-motion or dust-to-dawn, or other preferred additional-functions.
