Abstract
The utility model discloses a low power low power LED lighting bulb, comprising a lamp cap and a lamp housing closely connected with the lamp cap, wherein, a printed circuit board is clamped in the cavity of the lamp housing; one side of the printed circuit board toward the lamp cap is provided with a drive circuit of the LED while the other side is provided with a pin picture; and a lampshade covers the lamp housing. The lighting bulb is characterized in that LEDs are uniformly arranged on the pin picture of the printed circuit board through taking the axle wire of the lamp cap as the axes and according to the equidistant concentric circular ring; and each LED is slightly tilted relative to the axle wire of the lamp cap and has the same tilt angle.
Description
Technical field
The utility model relates to a kind of lighting bulb, especially adopts the bulb of low power LED as cold light source.
Background technology
At present, lighting bulb mainly adopts incandescent lamp and all gases lamp, these lamplight brightness are low, thermal losses is big, with the incandescent lamp is example, and it only is 40% that its electric energy changes into luminous energy most effective, and most of energy is converted into the heat of bulb, thereby cause bulb after work a period of time, surface temperature is very high.This has not only wasted the energy, and has significantly reduced the normal service life of bulb, simultaneously safety in production, life has been brought hidden danger.In addition, the common low-power LED luminous tube angle of divergence is little, and probably in 10-30 ° of scope, illumination zone is very limited, can not satisfy the requirement of illumination far away.
Summary of the invention
The purpose of this utility model is at existing light source above shortcomings, and it is very high to propose a kind of light effect, and thermal losses is little, keeps constant temperature during work, long service life, and the angle of divergence is big simultaneously, but the big low power LED light bulb of illumination zone.The utility model adopts low power LED to do light-emitting component mainly based on following factor:
The one, power consumption is little, only is 5%～10% of incandescent lamp generally, 10%～30% of electricity-saving lamp.
The 2nd, long working life is 5～10 years, and the maintenance expense is extremely low.And conventional bulb needs to change every year, maintenance expense height.
The 3rd and since the light beam that sends of LED be forward and have certain angle of divergence, so just can as incandescent lamp, need install reflector additional.And LED itself sends is coloured light, so just need do not filtered by coloured lens, thereby solve the problem of false demonstration and lens color drift, improved light utilization efficiency.
The 4th, because the interior every group of LED of bulb only is a luminescence unit in the whole lamp panel,, even individual groups LED breaks down, can not influence the luminous constituent element of other LED yet, thereby influence the whole structure of lamp as long as the lamp driver plate is reasonable in design.
The technical solution of the utility model is: a kind of LED illumination bulb comprises lamp holder, with the close-connected lamp housing of lamp holder; Printed circuit board (PCB) is stuck in the lamp housing inner chamber; Printed circuit board (PCB) is provided with the drive circuit of light emitting diode towards the one side of lamp holder, the pin figure of another side distribution light emitting diode, lampshade covers on the lamp housing, it is characterized in that: with the lamp holder axis is the axle center, according to equidistant donut evenly distributed light emitting diode on the pin figure of described printed circuit board (PCB), and each light emitting diode is with respect to the axis slight inclination of lamp holder, and the inclination angle is identical.
In the above-mentioned LED illumination bulb, each light emitting diode is 0 °-5 ° with respect to the inclination angle scope of the axis of lamp holder.
In the above-mentioned LED illumination bulb, be distributed with a plurality of apertures on the lamp housing.
In the above-mentioned LED illumination bulb, enough space natural heat dissipations are arranged between printed circuit board (PCB) and the lamp holder.
The utility model has the advantages that installation is convenient, easy to use, and luminous soft as the bulb of light source, the angle of divergence is big, but illumination zone has enlarged much than common bulb.Compare with common bulb, lighting bulb thermal losses of the present utility model is little, and it is hot to be not easy to generate heat, and makes the bulb outer wall keep permanent low-temperature condition.Owing to adopt light emitting diode, improved the service life of bulb greatly simultaneously, thereby reduced the cost that bulb updates as main light-emitting component.

Fig. 3 arranges schematic diagram according to the light emitting diode of the bulb of the utility model embodiment;
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the bulb structure schematic diagram according to the utility model embodiment.Wherein, standard lamp head 1, for example the E27 lamp holder closely is connected with lamp housing 2 by silicone rubber adhesive; Printed circuit board (PCB) 3 is stuck in lamp housing 2 inner chambers, and with vertical placement the in lamp holder 1 axis; Printed circuit board (PCB) 3 is provided with the drive circuit 6 of light-emitting component, the pin figure of another side distribution light-emitting component, the pin figure of the light emitting diode described in present embodiment (LED) 4 towards the one side of lamp holder 1.As shown in Figure 3, with lamp holder 1 axis is the axle center, according to equidistant donut evenly distributed light emitting diode 4 on the pin figure of described printed circuit board (PCB) 3, and each light emitting diode 4 is with respect to the axis slight inclination of lamp holder 1, and the inclination angle is identical, preferably at 0 °-5 °, the angle of divergence in conjunction with light emitting diode self, when opening whole light emitting diode group, will make that the light that whole light source is sent is bigger with respect to the angle of divergence of described axis, thereby make illumination zone wider.The tube core of drive circuit 6, printed circuit board (PCB) 3 and light emitting diode 4 adopts silicon rubber to bond together.Have enough spaces between printed circuit board (PCB) 3 and the lamp holder 1, be beneficial to natural heat dissipation.Preferably, be distributed with a plurality of apertures on the lamp housing 2, the heat that is beneficial to the generation of light-emitting component and circuit is by shedding in the chamber.
The specific embodiment of the present utility model only is used to make things convenient for those skilled in the art to understand the utility model, and should not be construed as the restriction to the utility model protection domain.Under the situation that does not break away from the utility model purport, distortion that those skilled in the art did and replacement also should be included in the protection domain of the present utility model.
