Heat dissipation, and the adapter seat is used for the positioning of the translucent cover and the lamp housing, so as to take into account the effects of fixing, light source and heat dissipation in a limited space.

Background technique

The traditional light bulb (llight bulb) or bulb lamp has been more than a hundred years since Edison invented the use of tungsten filament as a light source. Since the tungsten filament emits light in all directions (omnidirection), it does not output in a certain direction. There are more light sources, so the light sources such as candles or kerosene lamps are quickly replaced. At present, the market has accepted light sources with all-round light shapes.

However, due to the high power consumption of bulbs using tungsten filaments as the light source, that is, the illuminance provided by the power consumed per watt is quite poor among current light sources. Therefore, many R&D resources are invested in providing more energy-efficient Electric light source to replace the traditional tungsten bulb.

At present, the most accepted in the market is an energy-saving light bulb using a ballast, also known as an electronic light bulb, compact fluorescent lamp or integrated fluorescent lamp. Connectors to directly replace traditional tungsten bulbs. The advantage of this energy-saving bulb is that its energy-saving light efficiency is much higher than that of traditional tungsten bulbs. Under the same lighting conditions, the former consumes much less electricity, so it is called It is an energy-saving lamp, but compared with fluorescent lamps (especially T5 lamps), it is still a waste of energy.

However, this energy-saving light bulb is not completely flawless. First, unlike tungsten bulbs, energy-saving light bulbs will generate slight electromagnetic waves and microwaves when they are in use. The intensity of electromagnetic waves produced by energy-saving light bulbs per watt is about 4.67 milligauss , and about 3.3μW/cm ² with microwaves. In addition, due to the characteristics of ballasts and fluorescent lamps, energy-saving bulbs not only cannot be dimmed, they are not suitable for dimmable lamps, and they are not suitable for places that require frequent switching. In addition, in provincial At the end of the service life of light bulbs, trace amounts of mercury contained in energy-saving light bulbs are toxic substances and must be handled with care during transportation and disposal.

LED lighting is the electronic lighting product that consumes the least power in current lighting devices and is most in line with green energy. Manufacturers have been researching and developing LED lighting. The light source is not only a point light source, but also has directivity. Although it has the advantage of extremely low power consumption, it needs a heat dissipation design to spread the point light source and make it suitable for lighting.
