Description

Environmentally friendly electrodeless bulb body

technical field

The utility model relates to an electrodeless bulb, specifically, an environment-friendly electrodeless bulb body.

Background technique

Electrodeless lamps belong to the fourth generation of lighting products. They have no filaments and no electrodes. They are short for electrodeless gas discharge fluorescent lamps. Compared with traditional light sources such as energy-saving lamps, metal halide lamps, and high-pressure sodium lamps, they have significant advantages. At present, the fluorescent powder of electrodeless lamp bulbs on the market is made of halogen powder, that is, calcium halophosphate. Although halogen powder is cheap, its luminous efficiency is not high enough, its thermal stability is poor, its light decay is large, and its luminous flux maintenance rate is low; the mercury in gas-filled lamp bulbs is usually liquid mercury, and when the electrodeless lamp is working, the temperature of the tube wall rises, resulting in The mercury pressure rises significantly, far exceeding the optimal mercury pressure of 0.8Pa; due to the high concentration of mercury atoms, internal friction-resonance absorption is caused, and the intensity of ultraviolet rays decreases with the rise of temperature, resulting in a decrease in luminous efficiency--temperature rise light Moreover, in the process of making lamps, mercury atoms are easy to volatilize, which not only leads to the loss of mercury, but also pollutes the air; the amount of liquid mercury is also difficult to control. In addition, it is also difficult to recycle liquid mercury in waste bulbs. .

Further, both the main amalgam and the auxiliary amalgam are solid mercury.

Still further, the bulb housing includes a glass layer, a protective layer and a phosphor layer laminated from outside to inside.

Specifically, the protective layer is made of aluminum oxide; the fluorescent powder layer is made of trichromatic fluorescent powder.

Furthermore, the auxiliary indium mesh is closely attached to the side wall of the concave cavity.

Compared with the prior art, the utility model has the following advantages and beneficial effects:

(1) The utility model is not only simple in structure, but also low in cost and easy to use.

(2) The light bulb housing in this utility model is made of glass, with a three-primary-color phosphor layer on its inner wall, and an aluminum oxide protective film is also provided between the three-primary-color phosphor layer and the inner wall of the light bulb shell. Among them, the luminous rate of the three-color phosphor is higher than that of the traditional halogen powder, and it can effectively save energy when used as a raw material for the phosphor; and the aluminum oxide protective film between the three-color phosphor layer and the glass not only makes the primary color fluorescent The powder is more evenly and effectively attached to the inner wall of the bulb shell, and can absorb the ultraviolet rays emitted outside the lamp, and can effectively prevent the chemical reaction of sodium ions in the glass.

(3) The main amalgam and the auxiliary amalgam in this utility model are both solid mercury. According to the temperature of the pipe wall or the "position temperature" where the solid mercury is placed, through experiments, the solid mercury that can maintain the mercury pressure of 0.8Pa can be selected to obtain The best luminous brightness achieves a real energy-saving effect; and the volatilization rate of solid mercury is low, there is basically no mercury loss, and its distribution is very uniform, which is convenient for precise control of the amount of mercury used in the lamp, thereby reducing its environmental pollution; In addition, for The recovery of solid mercury in waste light bulbs is also very convenient.

(4) The light bulb housing in this utility model is made of soft or hard glass, so as to meet the needs of different prices and quality, and lay the foundation for the wide-scale promotion of this product.

(5) The utility model is equipped with an auxiliary indium mesh in the bulb shell, and the auxiliary indium mesh is also provided with an auxiliary amalgam. The auxiliary indium mesh is closely attached to the concave cavity. The lamp can reach 80% of the light output within 10s; when the lamp is turned off, the indium grid cools down quickly, collecting most of the mercury atoms in the bulb to prepare for the next start-up, and the auxiliary amalgam ensures the rapid light output Stablize.
