Description

LED bulb

Technical Field

The utility model belongs to the technical field of the illumination and specifically relates to a LED bulb is related to.

Background

As a new energy source, the LED has been widely used in the field of lighting due to its advantages of good energy saving effect, long life, and the like. The LED lamp changes the principle of tungsten filament luminescence of an incandescent lamp, utilizes electric field luminescence, and has the advantages of high luminous efficiency, no radiation, long service life, low power consumption, environmental protection and energy conservation. A common LED bulb generally includes a lamp holder, a driving power supply, a light-transmitting bulb casing and an LED light-emitting device, the driving power supply is disposed in the lamp holder, the LED light-emitting device is disposed in the light-transmitting bulb casing, the LED light-emitting device is electrically connected to the driving power supply, and the light-transmitting bulb casing is disposed on the lamp holder to form a whole lamp. The printing opacity cell-shell of LED bulb on the market at present is mostly the bubble of being made by the glass material, and in case the LED bulb of this kind of structure breaks, and glass splashes and easily causes the incident, has the potential safety hazard when using.

Disclosure of Invention

The utility model aims to solve the technical problem that a LED bulb with simple structure and higher use safety is provided.

The utility model provides a technical scheme that above-mentioned technical problem adopted does:

the utility model provides a LED bulb, includes lamp holder, drive power supply, glass bulb and LED illuminator, drive power supply set up the lamp holder in, LED illuminator set up the glass bulb in, LED illuminator with drive power supply electricity connect, the glass bulb set up the lamp holder on, the outside cladding of glass bulb be provided with the printing opacity protective sheath.

The light-transmitting protective sleeve is arranged outside the glass bubble in a tight-fitting and coating mode, so that the inner wall of the light-transmitting protective sleeve is tightly attached to the outer wall of the glass bubble. Ensure the installation of printing opacity protective sheath at the outside stable cladding of glass bubble to play stable guard action to the glass bubble, the condition that effectively prevents that the glass piece from taking place to splash when the lamp body is broken into pieces takes place. The light-transmitting protective sleeve can be tightly coated outside the glass bubble through a thermal shrinkage process.

The light-transmitting protective sleeve is a colored light-transmitting protective sleeve. The colored light-transmitting protective cover enables the whole lamp to be used as a colored bulb, and simplifies the manufacturing process of the traditional colored bulb.

An insulating plastic shell is arranged between the lamp holder and the glass bulb, the lower part of the insulating plastic shell is arranged on the lamp holder, the driving power supply is arranged in the insulating plastic shell, and the glass bulb is arranged on the insulating plastic shell. The insulating plastic shell plays an insulating protection role for the driving power supply and other electrical appliance elements.

The LED light-emitting device is an LED filament. The LED light-emitting device is an LED filament, so that the whole lamp forms an LED filament lamp, and 360-degree full-angle light emission is realized.

The thickness of the light-transmitting protective sleeve is 0.015mm-0.2 mm. On the basis of ensuring the protection strength, the influence on the light transmission is reduced as much as possible.

Compared with the prior art, the utility model has the advantages of: simple structure sets up a printing opacity protective sheath through the outside cladding at the glass bulb, can realize the outside transmission of the light that LED illuminator launched through this printing opacity protective sheath one, realizes the illumination, can play the guard action to the glass bulb two, can effectively avoid whole lamp glass to splash and the incident that causes when taking place to break into pieces to the security of use has been improved.

fig. 2 is a schematic view of the exploded structure of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

The first embodiment is as follows: as shown in fig. 1 and 2, the LED bulb comprises a lamp holder 1, a driving power supply 2, a glass bulb 3 and an LED light-emitting device 4, wherein the driving power supply 2 is arranged in the lamp holder 1, the LED light-emitting device 4 is arranged in the glass bulb 3, the LED light-emitting device 4 is electrically connected with the driving power supply 2, the glass bulb 3 is arranged on the lamp holder 1, and a light-transmitting protective sleeve 5 is coated outside the glass bulb 3.

In this embodiment, the light-transmitting protective sleeve 5 is tightly wrapped on the outer portion of the glass bulb 3, so that the inner wall of the light-transmitting protective sleeve 5 is tightly attached to the outer wall of the glass bulb 3. Ensure printing opacity protective sheath 5 and install at the outside stable cladding of glass bulb 3 to play stable guard action to glass bulb 3, the condition that the glass piece takes place to splash when effectively preventing the lamp body from breaking into pieces takes place. Wherein the light-transmitting protective sleeve 5 can be tightly coated and arranged outside the glass bulb 3 through a thermal shrinkage process.

In this embodiment, an insulating plastic housing 6 is disposed between the lamp cap 1 and the glass bulb 3, a lower portion of the insulating plastic housing 6 is mounted on the lamp cap 1, the driving power supply 2 is disposed in the insulating plastic housing 6, and the glass bulb 3 is mounted on the insulating plastic housing 6. The insulating plastic shell 6 plays an insulating protection role for the driving power supply 2 and other electrical appliance elements.

In this embodiment, the LED lighting device 4 is an LED filament. The LED light-emitting device 4 is an LED filament, so that the whole lamp forms an LED filament lamp, and 360-degree full-angle light emission is realized.

Example two: the other parts are the same as the first embodiment, except that the light-transmitting protective sleeve 5 is a colored light-transmitting protective sleeve 5. The colored light-transmitting protective cover enables the whole lamp to be used as a colored bulb, and simplifies the manufacturing process of the traditional colored bulb.
