Abstract
The invention belongs to the field of illumination, and provides an LED lamp. According to the LED lamp, LEDs are directly attached to the inner wall of a reflection cup, heat emitted by the LEDs is transmitted out in a heat conduction mode, the problem that the LEDs are poor in heat dissipation effect due to the fact that the bonding by smeared heat dissipation resin between an aluminum substrate and a radiator of an existing LED lamp is poor, and the service life of the LEDs is prolonged. In addition, heat dissipation grooves are formed in the cup wall of the reflection cup, therefore, the heat generated by the LEDs can be transmitted out through the reflection cup in the heat conduction mode and can also be transmitted out through the heat dissipation grooves in an air convection mode, and thus the heat dissipation efficiency of the LEDs is further improved. Further, the reflection cup is made to move back and forth in the axial line direction of the reflection cup by being rotated, the reflection cup can squeeze or not squeeze the opening of the reflection cup when the reflection cup moves back and forth in the axial line direction of the reflection cup, so that the opening of the reflection cup is made to become smaller or restore an original shape, and thus the light emitting angles of the LEDs are adjusted.
Description
Technical field
The invention belongs to lighting field, more particularly, to a kind of LED lamp.
Background technology
When the LED of existing LED lamp installs, LED is welded on aluminium base first, is fixed to it by screw more afterwards
On his component (as lamp body), and also need to painting radiating resin (as silica gel) between aluminium base and radiator and radiated, but
It is that radiating resin is often smeared inequality and led to bond between aluminium base and radiator bad, and then lead to the radiating effect of LED
Difference, reduces the life-span of LED.In addition, the radiator structure of LED is not integral structure, taking cost into account compare waste of materials,
The management cost of three to four materials more than considering from management.Furthermore, the rising angle of LED lamp cannot be adjusted.
Content of the invention
It is an object of the invention to provide a kind of LED lamp, solve between aluminium base and the radiator of existing LED lamp
Because smear radiating resin-bonding bad and lead to LED radiating effect difference problem, also solve the rising angle of LED lamp no
The problem that method is adjusted.
The present invention is achieved in that a kind of LED lamp, including lamp body, electric component, reflector and LED, described electric

Light cup, described reflector and reflector are coaxially disposed, and described LED is mounted on the inwall of described reflector, and described reflector is gold
Belong to reflector, described reflector is electrically connected with described electric component, and the wall of cup of described reflector offers some radiating grooves, institute
State the opening that radiating groove extends to described reflector from the bottom of described reflector, the bottom of described reflector and described lamp body
It is fixedly connected, the outer wall of described reflector offers external screw thread, is installed with the shape of one and described reflector in described reflector
The beaker flask matching, described beaker flask is coaxially disposed with described reflector, and the inwall of described beaker flask offers outer with described
The female thread of screw thread bolt.
Preferably, described reflector is aluminum reflector.
Specifically, described reflector is bowl-type.
Preferably, described reflector is aluminum reflector.
Specifically, described radiating groove equidistantly arranges on described reflector.
Specifically, described reflector is fixedly arranged in a fixed plate, and described fixed plate is fixedly arranged on described lamp body.
Specifically, described LED is mounted on the inwall of described reflector by SMT technique.
LED is directly mounted on the inwall of reflector by the present invention, and as the luminous source of cup, LED is carried out by reflector
Radiating, the heat that is, LED sends is gone out by reflector conduction of heat, and therefore LED need not be welded on aluminium base simultaneously by the present invention
Apply radiating resin to be radiated between aluminium base and radiator, solve between aluminium base and the radiator of existing LED lamp
Because smear radiating resin-bonding bad and lead to LED radiating effect difference problem, improve the service life of LED, save
Material, reduces production cost and handling of goods and materials cost.
In addition, the present invention passes through to open up radiating groove on the wall of cup of reflector, the heat that LED produces, not only by
Reflector conduction of heat is gone out, and can also be conducted in cross-ventilated mode by radiating groove, thus improving LED's further
Radiating efficiency.
Furthermore, the present invention makes reflector move back and forth along its axis direction by rotating reflector, in reflector along its axle
While line direction moves back and forth, reflector can extrude or not extrude the opening of reflector, so that the opening of reflector becomes
Little or restore to the original state, and then adjusting the rising angle of LED.

Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes.
As shown in FIG. 1 to 3, a kind of LED lamp provided in an embodiment of the present invention, including lamp body 1, electric component 2, reflection
Cover 3 and LED 4, in lamp body 1, the opening of reflector 3 is provided with a lamella lucida 5 to electric component 2, and lamella lucida 5 is used for blocking
Dust and waterproof, are provided with a conical reflector 6 in reflector 3, reflector 6 and reflector 3 are coaxially disposed, and LED 4 is mounted on
The inwall of reflector 6, reflector 6 is metal reflective cup, and reflector 6 is electrically connected with electric component 2, and electric component 2 can pass through
Reflector 6 is powered to LED 4, so that LED 4 is illuminated, and the wall of cup of reflector 6 offers the radiating groove 61 of some equidistant arrangements,
Radiating groove 61 extends to the opening of reflector 6 from the bottom of reflector 6, and radiating groove 61 can make reflector 6 produce elasticity change
Shape, that is, the opening of reflector 6 be squeezed and can diminish, can restore to the original state when not extruding, the bottom of reflector 6 and lamp body 1 are solid
Fixed connection, the outer wall of reflector 6 offers external screw thread 62, is installed with the cone of one and the mating shapes of reflector 6 in reflector 3
Shape cup 31, beaker flask 31 is coaxially disposed with reflector 6, and the inwall of beaker flask 31 offers female thread 32, the interior spiral shell of beaker flask 31
Stricture of vagina 32 is threadeded with the external screw thread 62 of reflector 6, thus beaker flask 31 and reflector 6 are linked together, and beaker flask 31
It is fixedly arranged in reflector 3, therefore reflector 3 is also linked together with reflector 6.
When the LED lamp of the present invention uses, rotate reflector 3 with handss, reflector 3 can backhaul along its axis direction
Dynamic, when reflector 3 moves along its axis to the direction being away from lamp body 1, the beaker flask 31 in reflector 3 also therewith to away from
