LED signs are mostly used for advertising. We usually see them in shops announcing the opening and closing service hours. Light Emitting Diodes, or LEDs as they are usually called, are light fixtures. They are semiconductor light sources that emit light when electricity passes through them.
We use and need waste paper bags to collect our trash, and we cannot do without them. They are usually made from plastics. Plastic is hazardous to the environment and is not biodegradable. It stays in the atmosphere for a long time and usually ends up in a landfill or a river or ocean. Waste bags are used in such a quantity that it is necessary to replace them with something friendlier to the environment. Hence, need for biodegradable waste plastic bags.
Use of white LED open signs and the reasons behind it.
We need signs for display advertisements. They are the mainstay of almost all the street shops and have been for a long time. They announce the presence of the shop to the customers. They have gone through some evolution over time. When they were first invented, they used regular light bulbs, which gave way to neon signs, leading to LED signs today. The main advantage of using white LED open signs are,
- They are very energy-efficient
- They are long-lasting and durable
- They are dynamic, meaning the color emitted by them can be changed just by adjusting the current passing through them
It is this versatility that has made them so popular in use worldwide.
Purpose of biodegradable waste bags
Plastic is not good for the environment, so industry regulators have come up with bio-degradable plastic, which, when discarded, just degrades naturally over time and does not pollute the atmosphere.
This becomes a necessity when we go somewhere nature is abundant around us, like a campsite, where we cannot afford to litter or pollute. Hence the use of biodegradable waste bags for camping. We have to use waste bags to collect the trash. In such places, it becomes very important to use biodegradable plastics so that we don’t pollute the environment.
