However, the height of the wall of the housing also constitutes a limit to the uniform diffusion of light by the light strip (since this wall imposes an exit angle), and thus constitutes a limit to the diffusion angle of the light (which is approximately 120°). limit, which means that there is no light emission at the cross-sectional level of the packaged LED

Embodiment Construction

[0054] Light strips according to specific embodiments of the present invention will now be described.

[0055] refer to figure 1 , The lighting strip according to one embodiment of the present invention includes a flexible support strip 1 including a main surface 10 and a secondary surface 11 opposite to the main surface 10 . The LED chips 2 and the electronic components 3 required for the operation of the LED chips are mounted on the main surface 10 of this flexible strip. exist figure 1 In the example shown in , the various LED chips 2 are arranged in a regular manner over the entire length of the support bar 1 . The line density of LED chips 2 along the support bar 1 can be very high, and the minimum distance d between two adjacent LED chips can be about 10 μm. Depending on the application, the distance between two adjacent LED chips can be larger, or indeed can vary along the support strip 1 . The electronic components associated with the LED chips are advantageously a...

Abstract

The invention relates to a luminous device comprising: a flexible support strip (1) having a length and a width; LED chips (2) arranged on a main surface (10) of the support strip (1) and distributedover the length of the strip in a continuous pattern; electronic modules (3) mounted on the support strip (1); conductor tracks formed on at least one of the surfaces of the support strip and electrically interconnecting groups of LED chips (4) and groups of electronic modules (3); and at least one encapsulation layer (6) covering at least the assembly of the LED chips (2) and letting through allor some of the light generated by the LED chips (2), the encapsulation layer (6) extending continuously over the entire length of the support strip (1) in said continuous pattern.

Description

technical field [0001] The present invention relates to a light emitting diode (LED) based flexible lighting device, such as a flexible lighting strip provided with LEDs. Background technique [0002] Basically, an LED chip usually comprises at least one p-n junction formed between a region of semiconductor material doped with p-type doping and a region of semiconductor material doped with n-type doping. Electrical connection terminals connected to each of the doped regions can be used to inject current and thus emit optical radiation in a wavelength range determined by the nature of the semiconductor material used. The light emitted by an LED chip is usually substantially monochromatic or within a given wavelength range. Additionally, the LED chips may be associated with illuminants capable of absorbing a portion of the optical radiation emitted by the LED and capable of emitting light at a wavelength other than that of the LED chip. For example, an emitter layer can be d...
