Abstract

The utility model relates to a universal LED low voltage DC bulb with which LED semiconductor light-emitting source of energy efficiency and long service life replaces the traditional filament, which is characterized in that on the screwed, plain or plastic sockets of different specifications for the filament bulb, LED is used to replace filament for light emission, glass lamp housing arranged (when glass lamp housing is not used, fix the exposed LED), the inconvenience that parts of the apparatus is modified to suit for the configuration of the two pins of the LED semiconductor due to the special requirement for the LED configuration eliminated, and drawbacks of low service life and high power consumption for filament bulbs removed so that the universal LED low voltage DC bulb can be directly used on all apparatus for filament bulbs with various identical voltage specifications as opposed to modification of any part of the apparatus.(e.g. universal LED low voltage DC bulb is directly used on flashlight, miner's lamp, signal lamp, joys, decorative apparatus, etc).

Description

A kind of general LED low-voltage direct small electric bulb

Affiliated technical field

The utility model relates to a kind of low-voltage direct small electric bulb, relates in particular to a kind of LED semiconductor light emitting light source energy-conservation and long service life and substitutes the luminous general low-voltage direct current small electric bulb of traditional filament.

Background technology

What traditional low-voltage direct small electric bulb used is the filament light-emitting small electric bulb, and this type of small electric bulb is easy to use to be subjected to using widely (for example using on flashlight, mine lamp, signal lamp, toy, decoration apparatus etc.); This type of small electric bulb by light-emitting filament and the glass shell after vacuumizing form, the efficient that electric energy is converted to luminous energy is lower, use very expense, for the higher filament of resistance has been adopted in the brightness that reaches regulation, in use the temperatures involved of Chan Shenging the service life of filament, thereby this type of filament small electric bulb is short service life, does not meet energy-conservation and long-life requirement.

A kind of LED semiconductor light emitting light source, along with the LED technology is constantly perfect, brightness improve constantly continuous attenuating with price, its energy-conservation and characteristic long service life more and more is subjected to people's attention, but this LED uses requirement that the relative voltage electric current is arranged and it external form as semiconductor two pin pipes, make people when using this LED illuminating source, the external form that will adapt to the semiconductor two pin pipes of the requirement of LED and LED to the parts of the utensil redesign of using LED or change utensil, thereby reduced the versatility of device component, increased the cost of utensil, influenced the selling price of utensil, influence LED in a way and popularize use widely, exemplary: the not versatility of existing LED flashlight parts and traditional flashlight parts.

The utility model content

Adapt to the inconvenience such as external form of LED semiconductor two pin pipes and solve low life-span of filament light-emitting small electric bulb, drawback that power consumption is big in order to overcome the parts that to change utensil because of LED, the purpose of this utility model is to provide a kind of general LED low-voltage direct small electric bulb, make the LED semiconductor light emitting light source of energy-conservation and long service life substitute the luminous small electric bulb of traditional filament, on the filament small electric bulb utensil of various identical voltage specifications, directly use, and need not change any parts on the utensil.(as on flashlight, mine lamp, signal lamp, toy, decoration apparatus etc., directly using general LED low-voltage direct small electric bulb).Make use energy-conservation and that long service life LED can popularize widely.

The technical scheme that its technical problem that solves the utility model adopts is: on the corresponding lamp tail of screw thread, plain weave or the Plastic lamp socket of filament small electric bulb all size, current-limiting resistance of series connection on the positive pole, as reach limit current margin can not use current-limiting resistance, 1-4 LED (along with improving constantly also of LED brightness can be with 1 LED) gone up in parallel or series connection to the small electric bulb of different voltage requests, be connected on the negative pole then, use specification to load onto glass lamp housing according to the general small electric bulb of LED again, do not use the glass lamp housing specification, exposed LED is fixed.

The beneficial effects of the utility model are, the LED semiconductor light emitting light source of producing energy-conservation and long service life substitutes the general LED low-voltage direct small electric bulb of filament light-emitting, general LED low-voltage direct small electric bulb can be on the filament small electric bulb utensil of various identical voltage specifications be directly used, make energy-conservation and long service life LED obtains more extensive, more universal utilization.

The specific embodiment

In Fig. 1, on positive pole, connect current-limiting resistance 2, LED luminous tube 3, according to the requirement of the general small electric bulb working voltage of LED, current-limiting resistance should be zero to 600 ohm usually.

In Fig. 2, on screw thread, plain weave or the Plastic lamp socket 1 corresponding lamp tail positive pole of filament small electric bulb all size, connect current-limiting resistance 2, LED luminous tube 3, connect then on the corresponding lamp tail negative pole, screw thread, plain weave or Plastic lamp socket 1 with filament small electric bulb all size glues together with glass lamp housing 4 again, to not needing the small electric bulb of glass lamp housing specification, can directly exposed LED be fixed with glue.

Claims

1. the LED semiconductor light emitting light source with energy-conservation and long service life substitutes the luminous general LED low-voltage direct small electric bulb of traditional filament, it is characterized in that on screw thread, plain weave or the Plastic lamp socket of filament small electric bulb all size, adopts LED to replace filament light-emitting.
