Embodiment Construction

[0075] figure 1 Shown is an LED lamp 1 having an LED module with a carrier (not shown) and a base connected to the carrier or a base 2 in the form of an Edison base with an external contact 3 and a foot contact 4 . The support is equipped with at least one LED and circuit components (not shown) arranged between the at least one cap and the at least one LED for driving the LED. Furthermore, the LED lamp 1 has a lamp body 5 with a recess (not shown) for accommodating at least that part of the carrier carrying the at least one LED. The lamp body 5 has a surface structuring for cooling the LED lamp 1 by heat convection. The surface structuring comprises a plurality of protrusions 6 or recesses 7 which are round in plan view. They are distributed largely evenly over the surface.

[0076] Despite the structuring, the shape of the illuminant or lamp body 5 or of the LED lamp substantially corresponds to the shape of a conventional incandescent light bulb. Outline 8 is drawn for ...

Abstract

The invention relates to an LED lamp and the manufacturing method therefore. The LED comprises an LED module provided with a support (29), and a lamp holder(2) connected with the support.The LED lamp may include at least one support equipped with at least one LED, a lamp base, at least one circuit component, interposed between the lamp base and the at least one LED, for operating the at least one LED, and a lamp body made of optically transmissive material with a recess for holding at least that part of the support which carries the at least one LED, the lamp body having surface structuring for cooling by thermal convection, wherein the surface structuring comprises a multiplicity of elevations, and wherein the elevations are respectively designed in the form of islands. According to the method of manufacturing the LED lamp, the support is configured with at least one LED, and is partially soaked in the pool provided with packaging materials, which can be hardened.

Description

[0001] The present invention application is a divisional application of the invention patent application with the application date of August 8, 2008, the application number "200880102875.5", and the invention name "light-emitting diode lamp". technical field [0002] The present invention relates to a light emitting diode (LED) lamp and a method for manufacturing an LED lamp. Background technique [0003] Despite the known advantages of LEDs in terms of lifetime, reliability, robustness and efficiency compared to other light sources, LED-based light sources are currently not able to replace conventional light sources in all areas of application. This is due in particular to the thermal properties of light-emitting diodes: when a maximum permissible temperature (the so-called knot temperature) typically in the range of 120° C. to 160° C. is exceeded, the LEDs are destroyed. The lifetime of LEDs is also strongly dependent on the operating temperature. Therefore, additional me...
