DE102005053304A1 - LED cover reflector for e.g. garden shelter, refracts LED light on reflector surface to uniformly distribute LED light in area, and illuminant fastened by lockable latch to reflector and exchanged - Google Patents

Abstract

The reflector refracts an LED light on a reflector surface to uniformly distribute the LED light in the area. An illuminant is fastened by a lockable latch to the reflector and exchanged. LEDs (h) are arranged in a series connection, where the LEDs are covered by an LED screen (i).

Description

Previous technical status:

at Previous LED bulbs (e.g., for E27, E14, GU10, MR16 socket), The light is blasted directly into the room and only shines a small area of a room. At a distance of the Such illuminant of about 2 m is only a circular area with illuminated a diameter of about 1 m.

Advantages and structure of the new system:

This LED ceiling reflector distributes the light of the illuminant uniformly in the Space (or outdoors), making for an optimal and pleasant Room lighting, with the advantages of an LED (durable, energy-saving).

The Drawing (picture 1) shows the basic structure of a ceiling light with the individual components. No measurements were given because the reflector can be made in different sizes - it has to only the length the distance rod of the LEDs to the reflector size and the beam angle of the LEDs are adjusted so that the light cone of the LED is the reflector crowded, but not about it lights up (Fig. 1-c).

The LED light is emitted upwards, reflected at the reflector and depending on the paint, scattered back down.

ever shiny the surface, the more light can be emitted into the room (better light output), however, then the individual light cone will be more visible. With less shiny paint the light becomes more even scattered, which then, however, also slightly greater loss of light Episode has.

The Bulbs are easy to connect through the BNC connection, as well as to exchange (for example with another color or a stronger light source) and can used for lighting of the above ranges. In addition, you can the bulbs through the locking of the BNC shutter not slip off. In each case 3 LEDs are connected in series - further groups of 3 can to be switched in parallel. The bulbs are supplied with 9.6V and are therefore over a voltage control on 12V sources operated (transformer or battery).

at Picture 1 is a revised one Drawing, as he will in the future should be produced.

Of the Operation can be over a transformer on the 230V mains, or also mobile via a 12V battery, which gets its energy from a solar module - so this light source can as good as everywhere be used and continue to operate in case of power failure.

Claims (2)

LED ceiling reflector, characterized in that the LED light is first refracted more or less strongly on a suitable reflector surface in order to distribute the LED light in this way evenly in the room. LED illuminant for LED ceiling reflector, thereby characterized in that it over a lockable lock attached to the reflector and easy through another (such as a different LED color) can be replaced. The arrangement of the LEDs is characterized by a series connection of 3 LEDs each. The LEDs are hidden by a shutter.
