Description

LED lamp

Field of technology

The technical solution is an LED luminaire from the electrical industry, which can be used as an energy-saving lighting element in common and more demanding interiors and exteriors and in all areas that need indoor and outdoor lighting.

Prior art

LEDs have very low power consumption, high energy efficiency and instant full power. Today, they are used instead of fluorescent lamps and other energy-saving lighting fixtures. LED luminaires are impact-resistant, do not mind frequent switching, make no sound, do not flicker and can be very small in size. At the same time, they have a long service life, do not burden the environment with UV radiation and possible contamination with heavy metals.

Despite the above advantages, technical solutions using LED techniques have certain drawbacks. A significant disadvantage of LEDs is that they are point light sources with directional radiation.

Until now, some LED luminaires have been fitted with a cover made of opal or translucent plastic material, and this cover disperses the high brightness of the spot LEDs. The disadvantage of this solution is the diffuse, spherical characteristics of the emitted light and also the reduction of the luminous flux. Also during production, there is an increase in the volume of stored different materials and material losses due to changes to another type of cover.

Another possibility is to create a linear light source, which is formed from individual LED chips using separate scattering filters located in front of the LEDs, and then to use a clear transparent plastic cover with an optical lens system formed by a pressing tool.

However, scattering filters must usually be made on a pressing, relatively expensive tool, with the effect of increasing the price of the luminaire. Diffusion filters also reduce luminous flux.

The above solution is very expensive, especially from the point of view of the production of tools for covers. For different radiation characteristics, eg deep-emitter, wide-emitter, standard emitter, etc., it is necessary to make a pressing tool with a different optical lens system for the cover. A major disadvantage of this solution is the need to change the tool on the production equipment to make the required type of cover. When changing the tool, there are downtimes on the machinery and, at the same time, material losses at the end of production of the original type and at the start of production of a new type of cover.

The essence of the technical solution

The essence of the technical solution is an LED luminaire, which is composed of a base, a reflector with electrical components and LEDs, and a transparent plastic cover, while the cover is provided with a foil that has an integrated nano-optical system of small lenses. The film is either on the inside of the transparent plastic cover or on the outside of the transparent plastic cover.

In the case of a cover with a foil inside the cover, the foil is attached to the block of the injection tool electrostatically or by a vacuum from the holes on the block.

In the case of a cover with a foil on the outside of the cover, the foil is attached to the block of the injection tool either electrostatically or by a vacuum from the openings of the block during production.

The optical system of small lenses on the foil is created mechanically by a raster cylinder, molding, printing, laser technology, etc.

The presented technical solution has the following advantages and advantages.

1) Covers for LED luminaires with different light emission characteristics, ie deep-emitter, wide-emitter or standard emitter, can be manufactured using a single injection tool.

2) There is no need to use scattering filters placed in front of the LEDs, which reduce the luminous flux and reduce the efficiency of the luminaire.

3) The use of opal or translucent material, which reduces the luminous flux and reduces the efficiency of the luminaire, is minimized or completely eliminated.

4) The need and volume of other stored materials and moldings is reduced.
