Abstract

The utility model discloses a novel light emitting diode (LED) bulb, which comprises a glass cover, a light guiding post, an LED lamp, an aluminum base plate, a radiating block, a casing and a lamp holder. The LED lamp is fixed in the center of the aluminum base plate, the aluminum base plate is installed on the radiating block which is sleeved in an opening cavity of the casing, and the lower end of the casing is fixedly connected onto the lamp holder. The lower end of the light guiding post is covered on the top surface of the LED lamp, the upper portion of the light guiding post penetrates through an inner cavity of the glass cover, and the lower end of the glass cover is fixedly connected to the upper end of the casing. Therefore, a containing space which contains the light guiding post, the LED lamp, the aluminum base plate and the radiating block is formed. The light guiding post is a cylinder and has two arc sides on the longitudinal section. Due to the fact that the light guiding post of the novel LED bulb is the cylinder and has two arc sides on the longitudinal section, therefore, the diverting effect of rays is better, and an illuminating angle is also better.

Description

The New LED bulb

Technical field

The utility model belongs to lighting field, particularly relates to a kind of New LED bulb.

Background technology

LED replaces the trend of conventional lamp such as incandescent lamp obvious day by day as lighting engineering of new generation, but because the characteristics of luminescence of LED itself; It is formed hot spot uneven round spot normally on objective plane; The center is very bright, and very fast in radial decay, so be not suitable for directly using as light source; And because the existence of its glare problem; If directly use as light source, can cause very big injury to eyes, could use as lighting source so need do the secondary light-distribution design the LED lamp.So, have the dealer to design lens module mode the LED lamp is done the secondary light-distribution design, but the mode of this lens can make the brightness of LED lamp reduce.LED bulb for using on ornamental lamp requires the irradiating angle of its light wide more good more, but its brightness is not had special requirement.Commonly use the leaded light post 10 (as shown in Figure 1) of LED bulb, its section is that both sides 101 are straight, divergence of beam effect bad (as shown in Figure 2).

The utility model content

The purpose of the utility model is the New LED bulb that provides a kind of divergence of beam effective.

For realizing above-mentioned purpose, the technical solution of the utility model is:

The utility model is a kind of New LED bulb, and it comprises cloche, leaded light post, LED lamp, aluminium base, radiating block, shell and lamp holder; Described LED lamp is fixed on aluminium base central authorities, and aluminium base is installed on the radiating block, and radiating block is nested with in the shell open-cavity, and the lower end of shell is fixed on the lamp holder; The lower end of described leaded light post is covered in the end face of LED lamp, and the top of leaded light post is arranged in the cloche inner chamber, and the lower end of cloche is fixed in shell upper end, forms one leaded light post, LED lamp, aluminium base, radiating block be contained in interior accommodation space; Described leaded light post is circular-arc cylinder for the longitudinal profile both sides.

After adopting such scheme because the utility model leaded light post is circular-arc cylinder for the longitudinal profile both sides, light disperse better effects if, the angle of irradiation also can be better.

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

Description of drawings

Fig. 1 is a leaded light axis of a cylinder mapping of commonly using the LED bulb;

Fig. 2 is a leaded light post light scattering sketch map of commonly using the LED bulb;

Fig. 3 be the utility model three-dimensional exploded view;

Fig. 4 is the utility model leaded light axis of a cylinder mapping;

Fig. 5 is the utility model leaded light post light scattering sketch map.

The specific embodiment

As shown in Figure 3, the utility model is a kind of New LED bulb, and it comprises cloche 1, leaded light post 2, vinyl cover 3, LED lamp 4, aluminium base 5, radiating block 6, shell 7 and lamp holder 8.

Described LED lamp 4 is fixed on aluminium base 5 central authorities, and aluminium base 5 is installed on the radiating block 6, and radiating block 6 is nested with in shell 7 open-cavities 71, and the lower end of shell 7 is fixed on the lamp holder 8.

The lower end of described leaded light post 2 is covered in the end face of LED lamp 4; The top of leaded light post 2 is arranged in cloche 1 inner chamber; The lower end of cloche 1 is fixed in shell 7 upper ends; Cloche 1 and shell 7 form an accommodation space in being contained in, and described leaded light post 2, vinyl cover 3, LED lamp 4, aluminium base 5, radiating block 6 all are nested with in the accommodation space that cloche 1 and shell 7 form.

Like Fig. 4, shown in Figure 5, described leaded light post 2 is circular-arc cylinder for longitudinal profile both sides 21, is cydariform.

The emphasis of the utility model just is: the leaded light post is circular-arc cylinder for the longitudinal profile both sides.

The above; Be merely the utility model preferred embodiment; The profile of leaded light post can have multiple; So can not limit the scope that the utility model is implemented with this, the equivalence of promptly doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.

Claims

1. New LED bulb, it is characterized in that: it comprises cloche, leaded light post, LED lamp, aluminium base, radiating block, shell and lamp holder; Described LED lamp is fixed on aluminium base central authorities, and aluminium base is installed on the radiating block, and radiating block is nested with in the shell open-cavity, and the lower end of shell is fixed on the lamp holder; The lower end of described leaded light post is covered in the end face of LED lamp, and the top of leaded light post is arranged in the cloche inner chamber, and the lower end of cloche is fixed in shell upper end, forms one leaded light post, LED lamp, aluminium base, radiating block be contained in interior accommodation space; Described leaded light post is circular-arc cylinder for the longitudinal profile both sides.
