Abstract

The utility model discloses an LED lamp bulb, which comprises a lampshade. The two ends of the lampshade are connected with a base and a contact is arranged on the base. The lower part of the lampshade is provided with a radiator. The connection part of the radiator and the lampshade is integrally provided with a heat radiation connection board. The upper part of the heat radiation connection board is connected with a bulb carrying board. The lower part of the heat radiation connection board is connected with an LED substrate. LED lamp beads are arranged on the bulb carrying board. The plurality of LED lamp beads are connected in series with each other so as to form lamp sets. The longitudinally arranged lamp sets are connected in parallel with each other and a gap is respectively arranged between every two adjacent lamp sets. According to the utility model, the brightness of the LED lamp bulb is improved. Due to the characteristic of the parallel connection mode, when one lamp set is damaged, the normal operation of the other lamp sets is not influenced. Since the lamp sets are longitudinally arranged and gathered, the problems that most LED bulbs are low and non-uniform in brightness, poor in illumination effect, low in luminous efficiency and severe in optical attenuation are solved. Meanwhile, the longitudinal arrangement of the lamp sets facilitates the heat radiation. Therefore, the damage of the lamp sets caused by the local high temperature is avoided.

Description

A kind of LED bulb
Technical field
The utility model relates to a kind of lighting bulb, particularly a kind of good heat dissipation effect, the LED bulb that illuminating effect is outstanding.
Background technology
Lighting bulb roughly comprises Halogen lamp LED, incandescent lamp, electricity-saving lamp and LED lamp, and the LED bulb has low-power consumption, high brightness, and color category is abundant; Volume is little, and the life-span is long, and the light quality is high, and is radiationless basically; LED is simple in structure, internal carrier structure, and anti-seismic performance is good, and bright lamp response speed is fast; But the LED bulb structure is single at present, and single led lamp pearl power is little, generally the mode of a plurality of LED lamp pearl series connection or parallel connection is combined as a bulb as lighting bulb, but because LED lamp pearl irradiating angle is little; Colour temperature is low, and light is more dazzling, occurs on the LED bulb, the dark space having occurred when indivedual LED lamp pearls damage, and has influenced the integral illumination effect; The most brightness of LED bulb is low and inhomogeneous, and illuminating effect is bad, and luminous efficiency is low, and optical attenuation is serious; Shortcomings such as LED lamp interior light loss consumption is big, non-uniform light, along with the increase of LED power, quantity of heat production too much, bad if heat dissipation problem solves; Heat concentrates in the small-sized chip, then can faster devices wear out, and reduction of service life, even cause chip to burn.
The utility model content
In order to overcome the deficiency of prior art, the utility model provides a kind of good heat dissipation effect, the LED bulb that illuminating effect is outstanding.
The utility model solves the technical scheme that its technical problem adopted:
A kind of LED bulb comprises lampshade, and the lampshade two ends are connected with base; Described base is provided with contact, and the lampshade bottom is equipped with radiator, and radiator and lampshade junction have been wholely set the heat radiation connecting plate; Said heat radiation connecting plate top is connected with the bulb bearing plate, and heat radiation connecting plate bottom is connected with the LED substrate, and the bulb bearing plate is provided with LED lamp pearl; Several LED lamp pearls are connected into the lamp group, and the lamp group is vertically arranged, and are connected in parallel between the lamp group and are provided with spacing;
As the improvement of such scheme, laterally be wholely set raised line on the said lampshade;
As the further improvement of such scheme, said radiator periphery has been wholely set some heat radiation raised lines;
Further preferred, said heat radiation connecting plate bottom is wholely set the clamping convexity of clamping LED substrate, and heat radiation connecting plate top is wholely set the draw-in groove of clamping bulb bearing plate.
The beneficial effect of the utility model is: the utility model is through being connected into the lamp group with several LED lamp pearls, and the lamp group is connected in parallel and vertically arranges then, and at intervals; Not only can improve the brightness of LED bulb like this; And be connected in parallel and make lamp group can not have influence on the operate as normal of other lamp groups after damaging, vertically to assemble and arrange that to have solved the most brightness of LED bulb low and inhomogeneous, illuminating effect is bad; Luminous efficiency is low; Shortcomings such as optical attenuation is serious, and can help heat radiation prevent that local temperature is too high and cause the lamp pearl to damage.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the front view of the utility model;
Fig. 2 is the corresponding zoomed-in view in Figure 1A place;
Fig. 3 is the corresponding vertical view of Fig. 1.
The specific embodiment
With reference to Fig. 1 ~ 3, a kind of LED bulb comprises lampshade 1; Lampshade 1 two ends are connected with base 6, and described base 6 is provided with contact 7, links to each other with external power source through contact; Lampshade 1 bottom is equipped with radiator 2, and radiator 2 has been wholely set heat radiation connecting plate 21 with lampshade 1 junction, and said heat radiation connecting plate 21 tops are connected with bulb bearing plate 3; Heat radiation connecting plate 21 bottoms are connected with the substrate 4 of LED, and bulb bearing plate 3 is provided with LED lamp pearl 5, and several LED lamp pearls are connected into the lamp group; The lamp group is vertically arranged; Be connected in parallel between the lamp group and be provided with spacing, the heat of generation passed when heat radiation connecting plate 21 can work the lamp pearl, had good heat-radiation effect; LED lamp pearl 5 is connected into the lamp group can strengthen its luminosity, is connected in parallel between the lamp group to make a lamp group damage the operate as normal that can not have influence on other lamp groups afterwards.
Laterally be wholely set raised line 11 on the said lampshade 1, can have strengthened the diffracting effect of bulb when work, reduced optical attenuation.
Said radiator 2 peripheries have been wholely set some heat radiation raised lines 21, have increased area of dissipation, improve radiating effect.
Said heat radiation connecting plate 2 bottoms are wholely set the clamping convexity 22 of clamping LED substrate 4, and heat radiation connecting plate 2 tops are wholely set the draw-in groove 23 of clamping bulb bearing plate 3, and clamping can be convenient to the dismounting and the replacing of product.
The utility model is through being connected into the lamp group with several LED lamp pearls 5, and the lamp group is connected in parallel and vertically arranges then, and at intervals; Not only can improve the brightness of LED bulb like this; And be connected in parallel and make lamp group can not have influence on the operate as normal of other lamp groups after damaging, vertically to assemble and arrange that to have solved the most brightness of LED bulb low and inhomogeneous, illuminating effect is bad; Luminous efficiency is low; Shortcomings such as optical attenuation is serious, and can help heat radiation prevent that local temperature is too high and cause the lamp pearl to damage.
