Description
Technical field
The present invention relates to a kind of LED lamp pearl.
Background technology
In existing field of illuminating lamps, semiconductor lighting is a kind of new type of solid state cold light source, significant advantages such as its light source led (light emitting diode) has efficiently, energy-saving and environmental protection, long service life.Its power consumption is the 10%-20% of equal brightness conventional lamp only, is regarded as the revolution again in the lighting field, also by universally acknowledged be green replacement new light sources.
Along with the pursuit of people to quality of the life, people's environmental protection idea is also more and more stronger, particularly to some articles for daily use, requires health environment-friendly especially.Because common incandescent lighting device caloric value is big and can produce stronger radiation, thereby the development trend that is replaced by other forms of lighting device is gradually arranged.Wherein, the replacement lighting device that is expected most is exactly LED (light emitting diode) lighting device.At present, some fixed lighting devices have all progressively brought into use the LED lamp to throw light on as street lamp, indoor lamp, garden lamp etc.But for using the luminous portable lighting apparatus such as flashlight of miniature bulb (or lamp pearl), the LED technology also is not very perfect.Incomplete mode is embodied in: the internal control circuit slab integral of this LED lamp pearl is circular, and the volume that takes up room is bigger; When the lamp pearl was luminous, the heat of generation did not adopt heat abstractor that heat is distributed timely, influences the service life of lamp pearl; The mode that lamp holder connects control circuit board is generally, and two circular metal silks of anode and negative electrode directly are connected on the anode and negative contact of control circuit board, and such connected mode is easy to generate short circuit phenomenon.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, provides a kind of simple in structure, and cost is low, and overall appearance is small and exquisite, the LED lamp pearl of long service life.
The technical solution adopted in the present invention is: the present invention includes the LED lamp holder, the lamp tube, control circuit board, support the lamp tube, lamp base, described LED lamp pearl also comprises the heat radiation aluminium flake that is enclosed within described LED lamp holder outer surface, described heat radiation aluminium flake and described LED lamp holder constitute an integral body by fit, described integral body is enclosed within the inside of described lamp tube, the upper end luminous lighting part of described LED lamp holder by described lamp tube the top circular hole and be exposed at the outside of described lamp tube, described LED lamp holder also comprises positive electrode and negative electrode, described positive electrode and described negative electrode respectively with described control circuit board on just, negative pole links to each other, the first half of described support lamp tube is enclosed within the inside of described lamp tube and is weldingly fixed on described lamp tube, and the latter half of described support lamp tube also is enclosed within the inside of described lamp base and is connected to a fixed by welding manner with described lamp base.
Described heat radiation aluminium flake whole one-tenth round barrel shape also scribbles insulating barrier all around, and the circumferential edge of described heat radiation aluminium flake is along having cut and described positive electrode and corresponding two installation gaps of described negative electrode.
Described control circuit board also comprises metal bullet pin and metal connector, described metal bullet pin is fixedly mounted on the middle part of described control circuit board and contacts with the inner surface of described support lamp tube, described metal connector is fixedly connected on the centre position, bottom of described control circuit board, the welding hole that the ambroin of the lower end of described metal connector and described lamp base bottom forms fixes the described control circuit slab integral side of growth shape by the mode of welding.
The invention has the beneficial effects as follows: because the present invention also is with described heat radiation aluminium flake on described LED lamp holder, so just can be better, lamp holder sends during more in time use heat distributes the service life of prolongation lamp pearl.Owing to being connected of described electrode and described control circuit board be to connect around the described breach in the described heat radiation aluminium flake, two electrodes are separated by described heat radiation aluminium flake, prevent the phenomenon of the butt generation short circuit of two electrodes.Because what described control circuit board adopted is the rectangular shape structure, just makes whole system become compacter, more saves the space, equally also just makes the lamp pearl become more practical, smaller and more exquisite.Because each parts such as lamp tube, described heat radiation aluminium flake, described support lamp tube, described lamp base described in the present invention, all be to adopt the conducting metal standard element of producing with the method for punching press or stretching on the market, so just greatly reduce production cost, promptly reduce the market price, made this product can be generalized to common lighting field.
