Problems solved by technology

[0003] In order to solve the problems that the glass shell of the existing LED inflatable bulb is easy to be cold-fried and leaked, the collision is damaged, and the product cannot be randomly and quickly picked up, the solution of the present invention is to replace the transparent bulb of the LED inflatable bulb with a glass bulb. A soft bulb that can be deformed under the action of an external force, that is, an ultra-thin plastic bulb with a thickness of 0.02mm to 0.6mm, and the pressure of the high thermal conductivity gas filled in the bulb is higher than one atmospheric pressure, and the value range is 1.01 Atmospheric pressure to 5.0 atm

Embodiment 2

[0009] Embodiment 2 is a 6W LED inflatable soft bulb with an A60 type bulb, the schematic diagram is as figure 2 shown. The bulb is filled with a mixture of 55% hydrogen and 45% helium, and the air pressure is 1.2 atmospheres. The inner and outer surfaces of the bulb are covered with arc-shaped concave-convex surfaces; the LED light source is a 6W multi-"V"-shaped bead-connected LED illuminant. The lamp base and 6W drive circuit are similar to the corresponding conventional filament lamp products. Others are with embodiment 1.

Embodiment 3

[0010] Embodiment 3 is a 2W LED inflatable soft bulb with a C35 candle-shaped bulb, and the schematic diagram is as follows image 3 shown. The LED light source is a 2W double-helix bead-connected LED illuminant. The lamp base and 2W drive circuit are the same as the corresponding conventional filament lamp products. Others are with embodiment 1.

Embodiment 4

[0011] Embodiment 4 is a 15W white spherical bulb LED inflatable soft bulb with a diameter of 150mm, the schematic diagram is as Figure 4 shown. The inner and outer surfaces of the ultra-thin white plastic bulb with a thickness of 0.30mm to 0.35mm are smooth and coated with a coating that reduces the permeability of helium. Among them, the LED light source is a 15W double-helix LED bead-connected illuminant, and the lamp holder and 15W driving circuit are similar to conventional products. Others are with embodiment 1.

Abstract

An LED inflatable soft bulb is composed of a lamp base, a drive circuit, an LED light source, a core column and a shell, and is characterized in that a light transmitting bulb shell of the shell of the LED inflatable soft bulb is a soft bulb shell capable of deforming, namely an ultra-thin plastic bulb shell with the thickness being 0.02 mm-0.6 mm, and the inflatable pressure in the bulb shell ishigher than one atmospheric pressure. The LED inflatable soft bulb has the outstanding advantages that the bulb shell cannot be broken, and thus the potential safety hazard that people is likely to behurt by glass fragments generated when a conventional glass bulb shell is broken is avoided; cold-explosion air leakage, difficult to completely eliminate, of the glass bulb shell can also be avoided, and the reliability of a product is improved; especially uniquely, because the air pressure in the bulb shell is higher than one atmospheric pressure, the ultra-thin plastic bulb shell bulges outwards and becomes 'hard', when the bulb is subjected to air leakage, the air pressure in the bulb shell is decreased to be one atmospheric pressure, then the bulb shell becomes 'soft', a user presses thebulb shell by hand so that leakage can be tested to reject defective products; and in addition, the costs of the bulb shell and related processes can also be significantly lowered, so that the cost performance of the LED inflatable soft bulb is substantially increased.

Description

Technical field [0001] The invention relates to the field of semiconductor lighting sources, in particular to an LED inflatable soft bulb whose light-transmitting bulb shell can be deformed. technical background [0002] At present, the bulbs of all LED inflatable bulbs are glass bulbs, which will not be deformed under the action of external force, and will only be broken or broken when the external force is large. For example, for LED filament lamps, because the bulb needs to be filled with helium with high thermal conductivity, the entire shell must be sealed without air leakage, so the easy-to-seal glass bulb, glass stem and corresponding Sealing and exhaust technology (see patents: 2015107171744; 2016105719621; 2016100208583). However, the disadvantage of the glass shell is that it is prone to cold blast leakage and easy to break when colliding, which seriously affects the quality, reliability and safety of the product. If there is air leakage in the LED filament lamp,...
