The specific embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
A kind of LED bulb lamp member, as shown in Figure 1, comprise hemispheric lampshade 1, radiator, LED light source plate 5, lamp holder 11; Described radiator comprises cooling base 2, radiator shutter 3, conducting strip 4 and hollow tube 10; The double main structure body of doing this bulb lamp member of radiator.
The edge of described lampshade 1 is connected with cooling base 2; Conducting strip 4 is positioned at cooling base 2 upper surfaces, and LED light source plate 5 is fixed on conducting strip 4; Hollow tube 10 is positioned at cooling base 2 belows and is connected with cooling base 2, the inner space 8 that forms accommodating LED driving power of hollow tube 10; On the cooling base 2 of hollow tube 10 tops, have the through hole passed for electric connecting line; Radiator shutter 3 arranges around hollow tube 10, and is connected with hollow tube 10 with cooling base 2; Lamp holder 11 is connected with the hypomere of hollow tube 10.
Preferably, cooling base 2, radiator shutter 3, conducting strip 4 and hollow tube 10 are formed in one and make, and the material of cooling base 2, radiator shutter 3, conducting strip 4 and hollow tube 10 can all be selected heat-conducting plastic or thermal conductive ceramic; Also only material selection heat-conducting plastic or the thermal conductive ceramic of cooling base 2, radiator shutter 3 and hollow tube 10, and conducting strip 4 adopts the sheet metals such as aluminium flakes, copper sheet.On radiator shutter 3, have a plurality of holes, to increase cross-ventilation, be conducive to heat radiation.
The main part of radiator (cooling base 2, radiator shutter 3 and hollow tube 10) adopts heat-conducting plastic or thermal conductive ceramic to make, and heat-conducting effect is good on the one hand, and insulating properties are better on the one hand in addition, are not easy to cause the generation of body leakage phenomenon.Radiator shutter 3 comprises many airfoil fans, around around hollow tube 10 1 circles, to surrounding, dispels the heat 360 degree, has strengthened heat radiation area and zone, the temperature while effectively reducing by 5 work of LED light source plate.
When conducting strip 4 adopts sheet metal, can strengthen heat conductivility, the heat that makes LED light source plate 5 produce easily is transmitted on cooling base 2, further by radiator shutter 3, to disperse heat.When practical set, can be between LED light source plate 5 and metal conducting strip 4 the coated with thermally conductive silicone grease, further to strengthen thermal conductivity.
LED light source plate 5 can be stuck in by the mode of clamping on cooling base 2,, on cooling base 2, is provided with and integrated the first buckle 6 of cooling base 2 for this reason.Correspondingly, as shown in Figure 2, described LED light source plate 5 edges are provided with the notch 61 with described the first buckle 6 couplings.When LED light source plate 5 is installed, the first buckle 6 that only notch of LED light source plate 5 61 need to be aimed on cooling base 2, then on the contraposition card, low-angle of rear rotation can be fixed.
One of main purpose of the present invention is to make the structure of design to have characteristics easy to assembly, so lampshade 1 also is designed to be connected with cooling base 2 by buckle.The edge of described cooling base 2 raises up and forms flange 7, flange 7 is also integrated with cooling base 2, as shown in Figure 3, on the madial wall of described flange 7, be interval with a plurality of draw-in grooves 71, at the edge of lampshade 1, be provided with the second buckle 9 that a plurality of and described draw-in groove 71 coordinates.When lampshade 1, with after cooling base 2 engages, because draw-in groove 71 is spaced, make between lampshade 1 and cooling base 2 and counterrotating situation can not occur.
While carrying out lamp assembled, can carry out according to the following step:
1. heat-conducting silicone grease is coated in LED light source plate 5 back sides, then contraposition is stuck on the conducting strip 4 on cooling base 2, by rotating to an angle, that LED light source plate 5 is fixing.
2. the LED driving power is placed in to the space 8 in hollow tube 10, the output of LED driving power is connected with the both positive and negative polarity of LED light source plate 5.(can be weld or be electrically connected by the connector form)
3. the input of LED driving power is connected on lamp holder 11 (can be welding, can be also exempt from soldering tip directly press carry out electric connection).Lamp holder 11 is rotated into hollow tube 10 hypomeres (rotation is fixed with lamp base fixture after completing) subsequently.
4. buckle lampshade 1, assembling completes.
From above structure, can find out, this LED bulb lamp member, fansink designs is integral the main structure body of moulding, and the main part of radiator (cooling base 2, radiator shutter 3 and hollow tube 10) adopts heat-conducting plastic or thermal conductive ceramic to make, the effect that can guarantee to dispel the heat and take into account with insulation.Because the space 8 in hollow tube is insulating space, so driving power is without with forms such as heat-shrink tubes, doing the electrical isolation protection.Due to casing insulation, the adaptive scope of LED driving power is wide, also safer for the user.
From the process of assembling, can find out, the present invention has following characteristics:
1). between radiator and lamp holder 11, exempt from the transition insulating materials, can directly screw on lamp holder 11.
2) fixedly exempting between .LED light source board 5 and cooling base 2 screws, and can directly angle of rear rotation on LED light source plate 5 and cooling base 2 contraposition cards be fixed.
3). exempt to beat glue being connected between lampshade 1 and radiator, directly card is upper fixes.
In general, the present invention is easy to assembly aborning, and production efficiency is high.
