How to select lamp beads on the switch

    Common choices for lamp beads on switches include LED lamps and neon lamps. This article will explain the differences between the two types of lamps and the classification of LED. Hope it will be helpful to you in choosing lamp beads.

The difference between LED lights and neon lights

Working principle

    LED lights release energy through the recombination of electrons and holes to produce light. Neon lamps use a filament to heat neon gas to produce ionized gas molecules, thereby producing light. Specifically, neon lamps rely on the electrode tips at both ends of the lamp to ignite the rare gases in the lamp tube under a high-voltage electric field. Unlike ordinary light sources, which must burn tungsten filaments to high temperatures to emit light.

Energy consumption and efficiency

    The power consumption of LED lamps is generally much lower than that of neon lamps, and LED energy-saving lamps generate less heat, and most of the electric energy can be converted into visible light. However, neon lamps, with new technology, consume much less power. The power consumption per meter of lamp tube is 56 watts reduced to 12 watts per meter of lamp. At the same time, the service life of LED energy-saving lamps can reach more than 50,000 hours, far exceeding the 10,000 hours of neon lamps.

Temperature and working environment

    Because of its cold cathode characteristics, neon lamps have a lamp temperature below 60°C during operation, so they can be placed in the open air in the sun, rain or in water. LED lights are also highly adaptable to the working environment temperature, but may vary depending on the specific type and use.

Light characteristics

    The light of LED energy-saving lamps does not contain ultraviolet and infrared rays and does not produce radiation, which is beneficial to protecting eyesight. The neon lamp spectrum has strong penetrating power and can still maintain good visual effects in rainy or foggy days.

Environmental protection and safety

    LED energy-saving lamps do not contain harmful elements such as mercury and xenon, are easy to recycle, and do not produce electromagnetic interference. They require less voltage and current, generate less heat, and do not cause safety hazards. The performance of neon lamps in this regard may vary depending on the specific design and manufacturing process.

Classification of common LED lights

Classified by packaging form.

    Direct plug-in low-power LED lamp beads: This type of lamp beads has various specifications, including straw hat/steel helmet, round head, concave, oval, square (234), bullet head, flat head, (3/5/flat head/bread type ) Piranha, etc.

    SMD chip LED lamp beads: This type of lamp beads is generally divided into front-emitting light sources (such as 3020, 3528, 5050, etc.) and side-emitting light sources (such as 1016, 1024, etc.).

    High-power LED lamp beads: They do not belong to the SMD series because the power and current usage are different, and the photoelectric parameters are quite different. In terms of appearance, if there is no heat dissipation base (usually a hexagonal aluminum base), its appearance is not much different from that of ordinary patches.

Classified by color

    Red light, green light, yellow light, etc., these are classified according to the color of light emitted by LED lamp beads.

Classified by characteristics of the light-emitting surface

    Round lights, square lights, rectangular lights, etc. It can also be classified according to the type of luminous tubes, such as surface luminescent tubes, lateral tubes, micro tubes, etc.

    The design of the switch and the selection of lamp beads may vary depending on different application scenarios, user needs and technological developments. Therefore, when selecting switches and lamp beads, it is recommended to make comprehensive considerations based on the specific use environment and needs.
