Abstract

An LED bulb with a diffuser comprises a lamp holder, a radiating device, an LED light source device, a drive power source, and a transparent shell. The LED light source device is made by welding a plurality of LED chips to a flexible substrate and is fixedly connected to a light source connecting block at the top of the radiating device. The bottom of the radiating device is provided with a counterbore. The drive power source is disposed in the counterbore. An output circuit of the drive power source is connected with the LED light source device for power supply. The bottom of the radiating device is screwed to the lamp holder. An input circuit of the lamp holder is connected with the drive power source. The LED bulb further comprises the diffuser with a bottom opening. The LED light source device is disposed in the diffuser. The lower opening of the diffuser is connected with the light source connecting block. The LED bulb with the structure has the advantages that the LED light source device is covered with the diffuser, the simple structure can never be seen from the transparent shell, and the transparent shell and a decoration make the whole bulb attractive; light from the LED chips is diffused by the diffuser and turns softer and evener.

Description

A kind of LED bulb with diffuser

Technical field

The utility model relates to lighting, especially a kind of LED candle bulb.

Background technology

Currently available technology, LED has energy-conserving and environment-protective, low-power consumption, and the advantage that optical efficiency is high becomes the modern principal light source throwing light on gradually.Bulb is our conventional illuminating product of living, there is the interface of standard, bulb uses LED chip as light source, the problem existing is: described light source is made up of several LED chips, projectiveness because each LED chip emits beam, cause the uneven illumination of light source even, see through lampshade simultaneously and can watch the simple and crude shape of LED chip, affect the outward appearance of bulb.

Summary of the invention

The purpose of this utility model is: a kind of LED bulb with diffuser is provided, and it can make LED light source luminous even, and bulb entirety is more attractive in appearance, and sight is high.

The utility model is achieved in that a kind of LED bulb with diffuser, comprise lamp holder, radiating element, LED light source device, driving power and transparent outer cover, described LED light source device is welded on flexible base, board by some LED chips and makes and be fixedly connected on the light source connecting seat at radiating element top; One counterbore is arranged at the bottom of radiating element, and driving power is housed in counterbore, has output circuit to be connected power supply with LED light source device on power supply; Radiating element bottom is screwed together with lamp holder, and the input circuit on lamp holder is connected with driving power, it is characterized in that: also comprise the diffuser of a under shed, described LED light source device is positioned at diffuser, and the under shed of diffuser is connected with light source connecting seat.

Described a kind of LED bulb with diffuser, its special character is: on described light source connecting seat, have plug, connection-peg and described diffuser are pegged graft; The level of falling on the light source connecting seat of the lower end of heat dissipating housing and connection-peg bottom coordinates stop bit.

Described a kind of LED bulb with diffuser, its special character is: the size and shape of diffuser bottom cavity is consistent with the size and shape of LED light source device.

Described a kind of LED bulb with diffuser, its special character is: there is a decorating objects on the top of diffuser.

Described a kind of LED bulb with diffuser, its special character is: diffuser and decorating objects are integrated working of plastics, or decorating objects is embedded on diffuser.

A kind of LED bulb with diffuser of the utility model, owing to adopting such structure, LED light source device is being hidden by diffuser, watches less than its simple and crude structure from transparent lamp case, coordinates decorating objects, makes bulb overall appearance; The light that LED chip sends is through diffuser 5 scatterings, and it is soft, even that light becomes.

Fig. 3 is cutaway view of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of LED bulb with diffuser, a kind of LED bulb with diffuser, comprise radiating element 2, LED light source device 3, driving power and the transparent outer cover 4 of lamp holder 1, metal, described LED light source device 3 is welded on flexible base, board by some LED chips 31 and makes and be fixedly connected on the light source connecting seat 21 at heat dissipation metal device 2 tops, one counterbore is arranged at the bottom of radiating element 2, driving power is housed in counterbore, on power supply, has output circuit to be connected power supply with LED light source device; Bottom and the lamp holder of radiating element are connected, and the circuit of lamp holder is connected with driving power;

Also comprise the diffuser 5 of a under shed, described LED light source device 3 is positioned at diffuser 5, and the under shed of diffuser 5 is connected with light source connecting seat 21.

On described light source connecting seat 21, have plug 211, connection-peg 211 is pegged graft with described diffuser 5, and falling on the light source connecting seat 21 of the lower end of diffuser 5 and connection-peg 211 bottoms grades 212 coordinates stop bit.

Also comprise a diffuser 5, the shape of diffuser 5 bottom cavities and size are consistent with shape and the size of LED light source device, and diffuser 5 is inserted on LED light source device fixing, and LED light source device is completely capped;

There is a decorating objects 51 on the top of described diffuser 5, and decorating objects 51 is integrated working of plastics with diffuser 5, or decorating objects 51 is inlayed and is connected on diffuser 5;

Described LED light source device 3 by diffuser 5 shades, watches less than its structure from transparent lamp case, coordinates decorating objects 51, makes bulb overall appearance; The light that LED chip 31 sends is through diffuser 5 scatterings, and it is soft, even that light becomes.

Above-described is only preferential embodiment of the present utility model.It should be pointed out that for the person of ordinary skill of the art, in the situation that not departing from the utility model principle, can also make some improvement and modification, this is also considered as protection domain of the present utility model.
