Abstract The utility model relates to an explosion-proof light bulb. The explosion-proof light bulb comprises a hard glass bulb, a wick in the glass bulb and an inner filling gas, and a lamp cap at the tail of the glass bulb. The outer surface of the bulb is mechanically or chemically treated to a matte surface, or at the end of the bulb, that is, at the end of the bulb. The inner surface is partially covered with a reflective coating, and the outer surface of the other end is a mechanically or chemically treated frosted surface. The hard glass bulb has a small thermal expansion coefficient, which can reduce the chance of the glass shell exploding under the sudden temperature difference. The inner surface of one end of the bulb is covered with a reflective coating, and the outer surface of the other end is treated with a combination of matte surfaces, which not only improves the light. The lighting, thermal efficiency and softening of the light refraction can also make the 40W bulb reach the brightness equivalent to 60W bulb, and in the humid case, the surface of the glass mat frosted surface will be more transparent, transparent Better features, especially suitable for use in wet, water-sprayed areas such as bathroom heaters.
Patent No. ZL03258212.9
The utility model name is the core column of the concentrated light source bulb
The utility model provides a core column for polymerizing a light source bulb, which comprises a core barrel solidified by a foot wire and a bead body, which is formed by two pairs of four legs of different lengths, which are formed by a front and rear well support method and a bead body. The two core cylinders are respectively opposite to each other, and the two ends of the front and rear ends are fastened to the tungsten wire, and the two filaments are in a parallel shape; or the two core pillars are formed one after the other and the length is corresponding. The wire is fastened to the tungsten wire, so that the tungsten wire is formed in a diagonal shape, and the light source body is combined with the left and right inclined surfaces to be combined with the gourd-shaped bulb, and the circular lamp shell is refracted by the different sizes to obtain the upper and lower sections. The bright light source with different angular apertures, or combined with the circular light tube, produces the same fixed-point light source with two slope angles of light and coherent control, with obvious functional changes.
Patent No. ZL200420003847.7 Improvement of the name of the utility model bulb
SUMMARY OF THE INVENTION The present invention provides an improvement in the structure of a light bulb, comprising a base, a housing disposed on the base to form a sealed space with the base, and the material of the housing is composed of primary color glass on the base Two electrodes are disposed therein and each extends to the inside of the casing, and a filament is connected to the two electrodes, and the coil segments of the filament are arranged in parallel relationship with the central axis of the casing. Due to the refraction effect of the primary color glass, the utility model can make the light bulb have a high-luminance luminous effect, and can achieve the effects of long-lasting illumination, non-discoloration and long service life, and the structure of the filament can make the casing difficult to be blackened, Maintain better lighting.
