Abstract

The invention relates to an LED retrofit lamp (100) which comprises a lamp tube (1), an LED light-emitting engine (2) arranged in the lamp tube (1), and end covers (3) arranged at the two opening ends of the lamp tube (1). The LED light-emitting engine (2) comprises a circuit board (21) and at least one light source arranged on the circuit board (21). The LED retrofit lamp (100) further comprises a pair of maintaining structures (4) and at least one pair of elastic tensioning structures (5). The maintaining structures (4) are fixed at the two opposite ends of the circuit board (21) respectively. The elastic tensioning structures (5) are connected with the maintaining structures (4). The elastic tensioning structures (5) penetrate through the end covers (3) through one sides of the end covers (3) and are locked on the other sides of the end covers (3) in a clamping mode. In addition, the invention further relates to a method for manufacturing the LED retrofit lamp (100).

Description

technical field [0001] The invention relates to an LED retrofit lamp. In addition, the present invention also relates to a method for manufacturing the LED retrofit lamp of the above type. Background technique [0002] As we all know, LED lighting has irreplaceable advantages, such as energy saving, ultra-low power consumption, close to 100% electro-optical power conversion, the same lighting efficiency can save more than 80% energy than traditional light sources, and its life is longer. In view of the above advantages, more and more people use LEDs as light sources, such as a large number of LED retrofit lamps appearing on the market. This LED retrofit lamp has the outline of a traditional light source such as an incandescent lamp or a lamp tube, so that it can be used as a light source to better adapt to an existing lighting system. [0003] However, when replacing the traditional T8 / T5 type lamp, the circuit board on which the LED chips are disposed and the fixing of th...
