Abstract
The utility model provides a kind of LED bulb, it include: lamp cap, aluminium radiator and foundation ring, the lamp cap is connect by lamp holder with one end of the aluminium radiator, the foundation ring is connect with the other end of the aluminium radiator, the aluminium radiator is prismatic structure, the central position of each side of the prismatic structure is respectively arranged with the LED luminescence unit for the distribution that assumes diamond in shape, and the LED luminescence unit includes multiple first LED lamp beads.By adopting the above-described technical solution, the utility model is with compared with power lamps and lanterns, not only light emitting angle curve and HID lamp are almost the same, and are reduced in size in the market, length is steeped close to former HID lamp.
Description
Technical field
The utility model relates to technical field of lamps, in particular to a kind of LED bulb.
Background technique
HID using when by the reflector loaded in street lamp either bulkhead lamp etc. carry out the reflection to angular, come
Realize the angle that lamps and lanterns need to issue.HID size in the prior art is small, generates electric arc by inert gas to shine, sends out
Luminous point compares concentration, and light emitting angle curve is as shown in Figure 4.
For energy saving, has already appeared replace traditional HID lamp bubble using LED bulb in the prior art, still, due to
This LED bulb shines by LED lamp bead, and its aluminium thermal dissipation size is bigger, therefore smooth surface Regional Dispersion is larger.If made
It is directly replaced with LED bulb current currently on the market, light-emitting surface and original HID are widely different, and light emitting angle curve is such as
Shown in Fig. 6.
Therefore, it will lead to former reflective Lacquer finish and reflect angle difference, lamps and lanterns cannot be met in certain application scenarios (examples
Such as mine lamp, street lamp) under irradiation need.
Utility model content
The utility model provides a kind of LED bulb, to solve the above technical problems.
To solve the above problems, the one aspect as the utility model, provides a kind of LED bulb, comprising: lamp cap,
Aluminium radiator and foundation ring, the lamp cap are connect by lamp holder with one end of the aluminium radiator, and the foundation ring and the aluminium radiate
The other end of device connects, and the aluminium radiator is prismatic structure, the central position of each side of the prismatic structure
It is respectively arranged with the LED luminescence unit for the distribution that assumes diamond in shape, the LED luminescence unit includes multiple first LED lamp beads.
Preferably, the second LED lamp bead is additionally provided on each side, second LED lamp bead is located at LED hair
Position between light unit and the lamp cap.
Preferably, the LED bulb further includes cylindrical Transparent lamp shade, and the clear lamp enclosure radiates in the aluminium
The outside of device, and one end of the Transparent lamp shade is connect with the lamp cap, the other end is connect with the foundation ring.
By adopting the above-described technical solution, the utility model is in the market compared with power lamps and lanterns, not only light emitting angle
Curve is almost the same with HID lamp, and is reduced in size, and length is steeped close to former HID lamp.

Specific embodiment
The embodiments of the present invention are described in detail below in conjunction with attached drawing, but the utility model can be by right
It is required that the multitude of different ways for limiting and covering is implemented.
The one aspect of the utility model provides a kind of LED bulb, comprising: lamp cap 1, aluminium radiator 2 and foundation ring 3,
The lamp cap 1 is connect by lamp holder 6 with one end of the aluminium radiator 2, the other end of the foundation ring 3 and the aluminium radiator 2
Connection, the aluminium radiator 2 are prismatic structure, and the central position of each side of the prismatic structure is respectively set
There is the LED luminescence unit for the distribution that assumes diamond in shape, the LED luminescence unit includes multiple first LED lamp beads 4.Preferably, each described
The second LED lamp bead 5 is additionally provided on side, second LED lamp bead 5 is between the LED luminescence unit and the lamp cap 1
Position.
In the above-mentioned technical solutions, central position of the utility model in each side, which is respectively arranged with, assumes diamond in shape point
The LED luminescence unit of cloth, so that light source is concentrated on a region, this region is similar to the light emitting region of HID, light emitting anger
Line of writing music is as shown in Figure 5.By Fig. 4 and Fig. 5 it is found that the light emitting angle curve of the utility model and HID lamp base in the prior art
Originally it is consistent, ensure that light reflection position is identical, remained unchanged so that former HID lamp bubble be kept to be replaced rear light emitting angle.
By adopting the above-described technical solution, the utility model is in the market compared with power lamps and lanterns, not only light emitting angle
Curve is almost the same with HID lamp, and is reduced in size, and length is steeped close to former HID lamp.
Preferably, the LED bulb further includes cylindrical Transparent lamp shade 7, and 7 sets of the Transparent lamp shade dissipate in the aluminium
The outside of hot device 2, and one end of the Transparent lamp shade 7 is connect with the lamp cap 1, the other end is connect with the foundation ring 3.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
