Abstract

The utility model discloses a dimmable light-emitting diode (LED) bulb. The dimmable LED bulb comprises a base, wherein the base is provided with a light-transmitting cover; a circuit board is arranged between the base and the light-transmitting cover and is provided with light-emitting components and a rectifying module which is connected with the light-emitting components; the light-emitting components comprise an LED unit and a current-limiting resistor; and the LED unit consists of a plurality light-emitting diodes which are mutually connected in series or in parallel; and the LED unit is connected in series with the current-limiting resistor. On one hand, the circuit board is only provided with the light-emitting components and the rectifying module which is connected with the light-emitting components, a built-in power supply drive component of the conventional LED bulb is saved, the volume is reduced, the cost is reduced, and the LED bulb can be dimmed according to the requirements of users after an external dimmer is added, so that the design is more humanized; and on the other hand, the light-transmitting cover is in a three-quarter spherical shape, the illumination area is greatly increased, so an extremely good illumination effect can be achieved. Thus, the dimmable LED bulb has a good application prospect.

Description

But a kind of LED ball of modulated light bubble

Technical field

The utility model relates to lighting technical field, but particularly relates to a kind of LED ball bubble of novel modulated light.

Background technology

At present, the LED bulb lamp of more and more and type various kinds has also appearred in increasingly mature and universal along with the LED lighting engineering on the market; Existing bulb lamp generally comprises base, is provided with the wiring board of LED lamp pearl, diffuser and power drives assembly, and wiring board is arranged between base and the diffuser, and the power drives assembly provides electric energy for the LED bulb lamp; Because need the power drives assembly to supply power, and the output of power drives assembly is certain, then existing LED bulb lamp all can only send the light of certain intensity; Can not regulate light intensity according to needs of people, promptly not have the modulated light function, and the diffuser light-emitting area of existing LED bulb lamp is less; Generally be set at 1/2 spherical shape; Do not reach lighting effect,, be necessary the design of existing LED bulb lamp is proposed new improvement in view of above-mentioned defective.

The utility model content

To the problems referred to above, but the utility model provides a kind of modulated light and the effective New LED bulb lamp of diffuser light-emitting area.

The utility model is that the technical scheme that its technical problem of solution is adopted is:

But a kind of LED ball of modulated light bubble; Comprise base, said base is provided with diffuser, is provided with wiring board between base and the diffuser; It is characterized in that: said wiring board is provided with luminescence component and the rectification module that links to each other with luminescence component; Said luminescence component comprises LED unit and current-limiting resistance, and the LED unit is made up of some light emitting diodes in series or in parallel with each other, and said LED unit and current-limiting resistance are in series.

As the further improvement to such scheme, said rectification module is a bridge rectifier.

Further, said diffuser is 3/4 spherical shape.

Further, a radiator is installed between said base and the diffuser.

In addition, said radiator is a cup-like structure wide at the top and narrow at the bottom, on the outer wall of radiator, be provided with from top to bottom a plurality of, and the radiating fin that is arranged in parallel.

The beneficial effect of the utility model is: but the utility model is as a kind of LED ball bubble of novel modulated light; Can solve traditional LED ball bubble well can not modulated light and the imperfect problem of illumination effect; On the one hand, owing to only be provided with luminescence component and the rectification module that links to each other with luminescence component on the wiring board, and saved the built-in power drives assembly of traditional LED ball bubble; Not only volume reduces, cost descends; And after adding the external dimmer device, can carry out light modulation to LED ball bubble according to user's needs, design embodies hommization more; On the other hand, the diffuser of the utility model is 3/4 spherical shape, and illuminating area improves greatly, can reach good lighting effect; Therefore possesses good prospects for application.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is described further:

Fig. 1 is the utility model wiring board circuit connection structure sketch map;

Fig. 2 is the utility model blast structural representation;

Fig. 3 is the utility model overall structure sketch map;

Fig. 4 looks up structural representation for the utility model.

The specific embodiment

With reference to Fig. 1-Fig. 4, but a kind of LED ball of modulated light bubble comprises base 1; Base 1 is provided with diffuser 2, is provided with wiring board between base 1 and the diffuser 2, and wiring board is provided with luminescence component 3 and the rectification module 4 that links to each other with luminescence component 3; Luminescence component 3 comprises LED unit and current-limiting resistance, and the LED unit is made up of some light emitting diodes in series or in parallel with each other, and LED unit and current-limiting resistance are in series; Rectification module 4 is a bridge rectifier, the input termination civil power of rectification module 4, and its output connects the LED unit; If between the input of civil power and rectification module 4, insert light modulator 6, such as adjustable resistance formula light modulator, controllable silicon formula light modulator, then the utility model just can be regulated light as required; Tradition LED bulb lamp owing to be built-in with electric power driving module, is output as constant current or voltage; Do not have the ability of regulating the curtage size, therefore can only send the light of specific size, diffuser 2 is 3/4 spherical shape; Illuminating area improves greatly, can reach good lighting effect, and a radiator 5 is installed between base 1 and the diffuser 2; Radiator 5 is a cup-like structure wide at the top and narrow at the bottom, on the outer wall of radiator 5, be provided with from top to bottom a plurality of, and the radiating fin 51 that is arranged in parallel.

More than the preferable enforcement of the utility model is specified; Certainly; The utility model can also adopt the form different with above-mentioned embodiment; These do not constitute any restriction to this embodiment, and those of ordinary skill in the art should belong in the protection domain of the utility model conversion of under the prerequisite of the utility model spirit, being done that is equal to or corresponding the change.
