lighting device

technical field

The present invention relates to an illuminating device, and in particular to an illuminating device of light emitting diodes.

Background technique

As LED technology continues to advance, more and more products are designed to take advantage of the properties of LEDs. In addition to replacing the light tubes of the past, various light bulbs have also been developed one after another.

Light-emitting diodes are referred to as LEDs for short. Made of compounds containing Gallium (Ga), Arsenic (As), Phosphorus (P), Nitrogen (N), etc. Visible light can be radiated when electrons and holes recombine, so they can be used to make light-emitting diodes. It is used as an indicator light in circuits and instruments, or as a text or number display. Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light. Due to chemical properties, it is divided into organic light-emitting diode OLED and inorganic light-emitting diode LED.

Since lighting is an important part of human life, although the technology of light-emitting diodes is quite mature, people still hope that more lighting products that can improve the quality of life can be designed. In order to achieve various product designs, including heat dissipation, power connection, drive, and even manufacturing cost and complexity, there are various technical problems to be solved.

Contents of the invention

The light bar module is formed by connecting more than two light bars in series, there are two support points between the two or more series connected light bars, and the light bar module has two electrical connection points. Taking light-emitting diode light bulbs as an example, multiple light-emitting diode chips can be packaged in series to form a light bar. The light bars can be further connected in series or in parallel to form a series connection. For the chip of the light emitting diode, a positive voltage terminal and a negative voltage terminal are required, and these two electrical connection points can be connected to the voltage supply point of the driving circuit to drive the chip of the light emitting diode to emit light.

In addition, in some implementations, when the power of the light emitting diodes is low, the cooling gas may not be completely filled, and the air is kept at, for example, 3% or more. This can adjust the luminous effect to a certain extent, and can reduce the requirements of the manufacturing process and reduce a certain cost.

In some embodiments, the table top of the lamp holder is lower than the bottom of the light bar of the light bar module.

In some embodiments, at the support point, the metal support bar is connected to and supports the light bar module through a fastening structure. For example, there are certain bends, buckles, springs, hooks, grooves, and protrusions at the supporting points of the metal support bar or light bar, which can save the complicated engineering of welding, or even if welding is required, further Strengthen the stability of the structure.

In some embodiments, the metal support strips have substantially the same appearance characteristics as the metal conductive strips.

In some embodiments, the metal support bar and the light bar module form an assembly unit, form a predetermined shape, and are installed on the light-transmitting seat in the manner of the assembly unit. In this way, the complexity of assembly can be reduced to a certain extent.
