Problems solved by technology

However, the heat dissipation problem of LED lamps has always been a problem studied by various manufacturers. If the LED bulbs are excessive and the heat dissipation is not good, it will directly affect the life of the product and also affect the brightness. At present, some radiators are used in the market. , Some use inert gas filling, the effect is not too ideal

Embodiment 1

[0015] Composed according to the following volume percentage, helium 91%, hydrogen 5%, krypton 2%, nitrogen 2%, this mixed gas passes through the opening of the wick of the LED bulb, and fills it into a 5-watt LED bulb to reach a standard At atmospheric pressure, close the wick post again, the bulb forms a fully sealed state, and the lumen can reach 658. In the same way, the mixed gas is filled into a 4-watt bulb, and the highest lumen reaches 408.

Embodiment 2

[0017] Composed according to the following volume percentage, helium 92%, hydrogen 3%, krypton 3%, nitrogen 2%, the mixed gas passes through the opening of the wick of the LED bulb, and fills it into a 5-watt LED bulb to reach a standard At atmospheric pressure, close the wick column again, the bulb forms a fully sealed state, and the lumen can reach 656. In the same way, the mixed gas is filled into a 4-watt bulb, and the highest lumen reaches 409.

Embodiment 3

[0019] According to the following volume percentage, helium 92%, hydrogen 5%, krypton 1%, nitrogen 2%, the mixed gas of this ratio passes through the opening of the wick of the LED bulb, and fills it into a 5-watt LED bulb to reach a standard At atmospheric pressure, close the wick post again, the bulb forms a fully sealed state, and the lumen can reach 659. In the same way, the mixed gas is filled into a 4-watt bulb, and the highest lumen reaches 406.

Abstract

Disclosed are mixed gas for LED bulbs and a filling method the mixed gas. The mixed gas is made from, by volume, 90% to 92% of helium, 3% to 5% of hydrogen, 1% to 3% of krypton and 1% to 3% of nitrogen. Owing to movements of molecules of the mixed gas filling an LED bulb, heat in the LED bulb is evidently decreased, the temperature is lowered, the service life of the LED bulb is prolonged, and lumen of the LED bulb is improved. During filling, four inert gases are mixed and charged through an opening of a core post until reaching a standard atmospheric pressure; the LED bulb is never severely broken even after the LED bulb falls off, and injury by fragments is avoided.

Description

technical field [0001] The invention relates to a mixed gas, in particular to a mixed gas for an LED light bulb. Background technique [0002] Traditional incandescent lamps (tungsten filament lamps) have high energy consumption and short lifespan. Under the environment of global resource shortage, the production has been gradually banned by governments of various countries; the power of ordinary bulbs ranges from 20W-100W, while the power of energy-saving lamps ranges from 5W-65W. etc., using LED as light source, the power only needs 0.8W-12W to replace 15W-100W ordinary light bulbs and 5W-50W energy-saving lamps. General energy-saving lamps will change due to changes in ambient temperature, and their normal operating temperature is between 20 and 40 degrees. It takes 5 to 6 minutes to work to achieve stable brightness in winter (at low temperature). It is difficult for all lamps to work normally in a cold environment than in a warm environment, and the light is dim or acc...
