Description

Lamp.

Object of the invention

The present invention relates to a lamp of the type comprising one or more housed in a housing LED diodes and rechargeable power batteries.

Background of the invention

There are currently a wide variety of luminous devices that work with batteries, either to produce ambient lighting, or usable by way of Flashlight among other uses.

In these devices, the use of LEDs for light generation due to its advantages in front of incandescent bulbs or other light sources, since that LEDs are small, they don't usually need reflectors, Their performance is remarkably high and they generate little heat.

This has proliferated various types of flashlights and lamps that use this type of luminous elements.

An example is the flashlights, which can be used in case of emergency, but they present the problem that when not they are in use they are saved, since they are not aesthetic and when they are necessary are groped in places of complicated access, such as in drawers with other stored objects. Also always there is a risk that the flashlight has batteries or batteries Rechargeable sold out.

Another case is the emergency lamps, which they comprise a luminous element and a plate with a charger and a transformer with a generally integrated plug. These lamps emergency can be operated by a button or switch, but do not allow other use than to have a light minimum indirect in case of power failure in the power grid of supply, can not be used as decorative element and in few cases can project a beam of direct light on a point adequate, such as when it is usually the case that the power failure is produced by the fuses or the magneto thermal switch of security in a domestic installation.

There are also small lamps on the market decorative batteries that are usually battery operated and that are intended for use as an outdoor lighting element, such as in terraces and gazebos, being spending on batteries prohibitive as ambient light for daily use.

Lamps or devices that work with LED diodes are usually made up of an electronic board to the that one or more LEDs are connected. This board is associated to a rechargeable power batteries and have a charger electric. For charging the batteries, the board is connected to a connector to an external transformer that can be connected to the network. For him operation and operation of the lamp or flashlight comprises a button that can turn the unit on and off or by repeated pulsations activate various operating modes, such as intermittence or similar.

Description of the invention

The lamp of this invention has some technical features aimed at enabling optimized use and flexible as a lighting element, being suitable for various applications. This lamp is designed for use as a lamp decorative both indoors and outdoors, as a lamp emergency and as a flashlight projecting a beam of direct light.

Indeed, the lamp presents on the plate electronics a voltage sensor in the power connector. This sensor enables the automatic ignition of at least one of the LED diodes in case of voltage drop in the connector enabling an ignition as emergency light. In this way when the supply voltage to the electric transformer or disconnect the lamp, usually connected to the mains, the automatic ignition of the same from the accumulated energy in rechargeable batteries, allowing easy location and use. At rest the lamp is fed conventionally to through said transformer and also charges the batteries to replace them

The housing is constituted by a central body tubular that at one end has a base of material transparent and / or translucent in which it is housed at least an LED, while at the other end is a Tubular tulip in which at least one LED of illumination.

The base LED has the mission of locator, projecting indirect light on the surface over the one that is arranged the lamp. In addition, this light can be colored The base is attached to the body through a union of Easy disassembly bayonet for access to the internal mechanism. In a preferred situation the battery is supported on the inner surface of the base for easy change in case of failure or exhaustion

In turn the LED diode located in the tulip is intended for general lighting, preferably being of greater power than the base. The tulip has its lateral contour opal or translucent for the projection of an indirect light side that creates optimal ambient lighting. The aforementioned diode LED is focused so that it projects the main beam through the front hole of said tulip, so that the lamp is also usable as a flashlight with a powerful beam of light direct.

In addition the electronic board allows functions added for the control of on and off of the LEDs. Thus, by repeatedly pressing the button it is possible to leave both LEDs on, leave only the LED on the base or turn off the lamp.

Description of the figures

To complement the description that is being performing and in order to facilitate the understanding of characteristics of the invention, is attached herein descriptive a set of drawings in which, for illustrative purposes and not limiting, the following has been represented:

- Figure 1 shows a perspective view above of the lamp of the invention.

- Figure 2 shows a perspective view rear of the same lamp in the previous figure.

- Figure 3 shows a schematic view of the electric circuit of the lamp represented on the contour, in dashed line of the lamp housing.

Preferred Embodiment of the Invention

As can be seen in the figures referenced the lamp is constituted by a housing that it comprises with a central body (11), a base (12) at one end and a tulip (13) at the other end. Inside the housing is find an electronic board (2) associated with a push button drive (21) operable from outside the body (11). This board (2) is associated with two LEDs (31, 32), arranged in the base (12) and in a tulip (13) respectively for its on and off.

Lamp power is obtained through from an external transformer (4) pluggable to a connector (22) in the side of the body (11). This connector (22) is related to the electronic board (2). In turn, this electronic board (2) is connected with rechargeable batteries (5) for operation autonomous or emergency diodes (31, 32). On the plate (2) it find a charging circuit of said batteries (5).

On the electronic board (2) there is a voltage sensor (23) that detects the existence or not of voltage in the connector (22), which allows the electronic board to automatically cause the LEDs to light up (31, 32) by the energy accumulated in the batteries in case the power supply voltage on said connector (22) drop by below a predetermined value or threshold.

The base (12) is constituted as a socket transparent cylindrical shape, which has the diode incorporated LED (31) focused on the flat surface of the translucent base. The base (12) has notches on its sides corresponding with bayonet connection means (6) with the body (11) that allow opening and closing. On the inside face of the base (12) the batteries (5) are arranged in a battery holder or similar.

The tulip (13) existing at the upper end of the housing is constituted by a tubular body at whose base inside is the LED (32) lighting, focused axially through the front hole (14) of said tulip (13). The lateral contour (15) of the tulip (13) is translucent for the Indirect light diffusion when the LED is found (32) switched on.

Once the nature of The invention, as well as a preferred embodiment, is for the appropriate purposes that the materials, form, size and arrangement of the elements described may be modified, as long as this does not imply an alteration of the essential features of the invention claimed in continuation.
