Description

Omnidirectional's LED

Technical field

This utility model relates to LED technology, and more particularly to LED bulb.

Background technology

Electric filament lamp is prohibited in many western countries, and fluorescent lamp be not environmentally and often provide Than relatively low color rendering index.In order to reduce waste and use existing bulb interface, develop use The LED bulb of existing bulb interface.Now, become more and more popular and LED bulb is used as room lighting.By A considerable amount of heat is created, so the LED bulb of routine includes that radiator, radiation dissipate in LED chip Backing device and heat insulation lamp base.The used heat produced during lamp operation is passed to radiator And it is radiate by heat loss through radiation sheet devices.

With reference to A-19 or the LED bulb of the spheroidal for room lighting, its luminous intensity is divided The basic demand of cloth and brightness includes that the light that this lamp sends should be omnidirectional, and luminous intensity distribution should be use up Uniform possibly, and above and below bulb, the luminous flux in region should reach a setting value to avoid Light uneven.In order to manage the production of LED bulb, Energy Star (Energy Star) has issued LED Standard of illumination, which specify the luminous intensity distribution of omnidirectional's LED.Define omnidirectional light in the standard Bubble should have equally distributed luminous intensity (vertical axial is symmetrical) in 0 degree to 135 degree region.? Luminous intensity in this region should not surpass with the difference of the average canbdle power in whole 0 degree to 135 degree region Cross 20%.At least the 5% of total flux (lumen) must be launched in the region of 135 degree to 180 degree.This In the region meant that in 270 degree below bulb, luminous intensity should be big and uniform, And above bulb in the region in 90 degree, luminous intensity flux should be not little.

Owing to LED core film source is always installed in heat transfer surface, it is possible to the LED of realization is Big beam angle is 180 degree, and half-intensity beam angle is about 140 degree.Existing LED bulb is flat by being arranged on Many groups LED chip on surface, face is constituted, and therefore the beam angle of bulb can not be the widest.Some LED Bubble uses the given shape of enclosing cover lens to make bulb have broader beam angle, but this can not realize energy The homogeneous luminous intensity requirement of the star (Energy Star) in source.Chinese patent CN201589090 discloses " a kind of bulb ", it can realize the big angle of departure.But, due to its structure complexity and under bulb Portion requires there is radiator, so it is difficult to be manufactured.Radiator in the bottom of bulb also blocks light beam And therefore can not realize wide beam angle.

Utility model content

Technical problem is to provide a kind of omnidirectional LED bulb, its have simple structure, conventional installation, Good thermal diffusivity and uniform light distribution.

In order to solve the problems referred to above, it is provided that a kind of omnidirectional LED, it includes transmissive bulb shell, some curved The LED module (also serving as radiator) of song, circuit board, interface board (it connects LED module and lamp socket). LED chip is disposed on LED module plate so that uniform light beam has 320 degree or broader light beam Angle and high rear light intensity flux.This bulb structure has will not hinder any light from LED chip The radiator of intensity.All LED chip is all installed on the crooked metal sheet with good conductive properties. LED can be disposed in the upper part of metallic plate and reserve the low portion of metallic plate and be used as heat radiation Device, it guides the heat produced by LED chip to leave.LED module (is provided with the gold of LED chip Belong to plate) shape be made into elongated S-shaped, thus the light beam of the LED chip on LED module can To provide good and uniform light intensity.

According to an aspect of the present utility model, it is provided that a kind of omnidirectional LED bulb, including lamp socket, electronics Drive plate, interface board, at least three or more LED module, bottom plastic lamp housing and top are moulded Material lamp housing；Wherein said interface board has slit, thus described LED module can be mounted to described narrow In groove；Wherein said interface board has the slit for being attached to by described electronic driver plate；Institute State interface board and there is the conductive trace formed in its surface, thus by the generation of described electronic driver plate DC electric power can be supplied to described LED module by described interface board.

Alternatively, described upper plastic lamp housing and described bottom plastic lamp housing are by viscose glue or ultrasonic bond in succession Knot is to together.

Alternatively, described LED electronic driver circuit is integrated in described interface board.

Alternatively, described bottom plastic lamp housing has air vent, and described lamp socket near described lamp socket It it is screw pedestal.

Alternatively, for having 5 watts or the bulb of more low power consumption power, described bottom plastic lamp housing does not has Air vent.

In this utility model, 3 to 6 LED modules are arranged to provide wide beam angle.Light source is by cloth Putting away from the rear portion of bulb, therefore shading scope is the least.LED module is elongated, Thus the low portion of LED module can be processed into radiator to guide heat away from LED chip.Electricity Sub-drive plate is positioned in the low portion of bulb, and its some part actually away from thermal source and The inside of the metal screws pedestal of LED chip, which ensure that the more stable work of electronic driver plate Environment.It is thereby achieved that have the more stable of true omnidirectional light source and efficient LED bulb.
