Embodiment Construction

[0024] The invention relates to an LED lamp, the light source of which is an LED 20 . The LED lamp of this preferred embodiment is as image 3 , Figure 4 As shown, it includes a lamp body (not shown in the figure), heat sink 10 , LED 20 and reflector 30 .

[0025] Wherein, the reflector 30 is a light-gathering reflector, and this type of reflector 30 has a light-gathering reflective surface S31 with specific characteristics, which is used for converging the light emitted by the LED 20 into parallel light rays after reflection. Usually, the generatrix of the light-concentrating and reflecting surface S31 is a symmetrical parabola of finite length, the top of the parabola is open and the bottom is tightened. The curved surface of rotation formed by the path swept by the parabola rotating 180 degrees around its axis of symmetry is the light-gathering reflection surface S31, and the symmetry axis of the parabola is the central axis of the light-gathering reflection surface S31,...

Abstract

The invention relates to a light-emitting diode (LED) lamp. The LED lamp comprises a lamp body, a heat sink (10) arranged on the lamp body, an LED (20) and a reflector (30), wherein the LED (20) is arranged in the center of the heat sink (10) and is electrically connected with the lamp body to realize power-on / power-off; the reflector (30) has a collecting reflection surface (S31) to reflect the light given off by the LED (20); the reflector (30) is screwed with the heat sink (10), and the central line of the screw thread superposes with the axes of the collecting reflection surface (S31) andthe LED (20). The invention utilizes the coaxality of the thread fit to assemble the reflector and the heat sink through the screw thread; the screw thread of the reflector has the same axis of the collecting reflection surface and the screw thread of the heat sink has the same axis of the LED, thus the processing reference is little, the error is small and the coaxiality of the reflector and theheat sink is high; and when the LED has an axial error in position, the LED can be adjusted to a proper position by rotating the screw thread. Therefore, both coaxiality and axial displacement can beadjusted by using the LED lamp of the invention and the intensity of illumination and roughness of the central light spot can be increased.

Description

technical field [0001] The invention relates to an LED lamp, and more specifically relates to the improvement of the connection structure between the reflector and the heat sink in the LED lamp. Background technique [0002] As a new type of lamp light source, LED has many obvious advantages, such as energy saving and environmental protection, high luminous efficiency, anti-vibration, long life and so on. Now, LED has been widely used in the field of lamps, such as spotlight flashlights, head-mounted lamps and so on. [0003] However, LED also has some disadvantages, that is, when it is used in spotlights, it is easy to appear that the central spot is not uniform enough, and the roundness is not high. The size of the illumination spots obtained under the distance is also different. This makes the consistency of the lamps not high and affects the lighting effect of the product. [0004] The main reason is that the existing LEDs usually reflect and concentrate light through...
