Light emitting diode lighting device

Abstract

The invention provides a light emitting diode lighting device, comprising a metal base, at least a light emitting diode module, a light transmitting cover and two side covers, wherein the metal base is hollow column-shaped with openings at two ends; the light emitting diode module is a facet lighting module and is fixedly arranged at the outer side surface of the metal base; the light transmitting cover is connected with the metal base, and the light emitting diode module is arranged in the light transmitting cover; and the shape of the cross section of the side covers is similar to the shape of the whole cross section of the metal base connected with the lighting transmitting cover, and the side covers are used for closing two ends of the metal base and the light transmitting cover.

Description

technical field [0001] The invention relates to a light-emitting diode lighting device, in particular to a light-emitting diode lamp. Background technique [0002] At present, most of the lighting sources use fluorescent tubes. In the early days, T8 tubes were the main ones. Therefore, the lamps installed are generally T8 lamps for T8 tubes. The T5 tubes that came out later have higher color rendering and luminous efficiency than T8 tubes. Good, small size, less power consumption and gradually accepted by people. [0003] However, this type of lamp has a short service life and is easily damaged. Human eyes have different degrees of flickering and the color rendering index is quite different from that of sunlight. Moreover, the lamp tube contains toxic mercury components, which are easy to damage the environment. [0004] In recent years, due to the research and development of light-emitting diodes (sometimes referred to as LEDs in this specification), LEDs have the advantag...

AI Technical Summary

Problems solved by technology

Therefore, when multiple light tubes must be connected in series or light tubes must be installed in various positions in response to lighting requirements, the current LED lamps obviously have deficiencies, which will limit the flexibility of installation

[0006] Moreover, the structure of existing LED lamps includes connectors, the overall structure is relatively complex, and many components are required, and the lamp holder and lampshade must also be prepared additionally, which increases the cost of the entire lamp, complicates the production process, and is inconvenient to install.

For example, most of the metal bases of the existing LED lamp structures are elongated metal bases with slots, and there are longitudinal baffles inside. Therefore, when setting the LED module, the LED module must be aligned with the metal base. Slots and stoppers are prone to defects in the process

In addition, the previous technology mostly used LED modules as point light sources to manufacture lamps, and the steps of connecting LED modules and metal bases had to be repeated many times, which not only made the preparation steps cumbersome, but also easily increased the probability of defects
