Abstract
A light-emitting diode (LED) lamp comprises a substrate, an LED module and a plurality of locking parts which fix the LED module on the substrate, wherein, the LED module comprises a circuit board and a plurality of LEDs arranged on the circuit board; the LED lamp also comprises elastic fasteners sleeved on the locking parts; the elastic fasteners are stuck between the substrate and the circuit board of the LED module. The LED lamp in the invention can fix the locking parts and the LED module together in advance via the elastic fasteners; when the LED module is assembled, the locking parts can not fall off the LED module, thereby simplifying the assembly.
Description
Technical field
The present invention relates to a kind of lighting device, particularly a kind of led lamp.
Background technology
Light emitting diode has many characteristics such as environmental protection, power saving, life-span length and is applied to various fields widely as a kind of light emitting source efficiently.
Traditional led lamp comprises a tabular radiator and some light emitting diode module that is installed on this radiator bottom one side.When light emitting diode was lighted, the light emitting diode module that is installed in the radiator bottom played illuminating effect, and radiator plays the effect to light emitting diode module heat radiation and protection light emitting diode module.Often directly light emitting diode module is fixed on the radiator in the prior art by some screws, assembling, unloading process is comparatively loaded down with trivial details, waste time and energy, especially in the work high above the ground assembling process, screw often comes off from light emitting diode module easily, makes that the assembling of light emitting diode module is more difficult.
Summary of the invention
In view of this, be necessary to provide a kind of and can simply assemble the led lamp of light emitting diode module.
A kind of led lamp, comprise a substrate, a light emitting diode module and this light emitting diode module is fixed on some locking parts on this substrate, this light emitting diode module comprises a circuit board and some light emitting diodes that is installed on this circuit board, this led lamp also comprises the spring secures rail to sleeper that is set on the locking part, and described spring secures rail to sleeper is interposed between the circuit board of substrate and light emitting diode module.
Compared with prior art, led lamp among the present invention can be with locking part and light emitting diode module predetermined fixed together by spring secures rail to sleeper, when the assembling light emitting diode module, locking part can not come off from light emitting diode module, thereby simplifies its assembling.
The invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the three-dimensional exploded view of a preferred embodiment of led lamp of the present invention.
Fig. 2 is the three-dimensional combination figure of the led lamp among Fig. 1.
Fig. 3 is the cross-sectional view of the led lamp among Fig. 1.
Fig. 4 is similar to Fig. 3, but light emitting diode module wherein is locked together in by flexible member with locking part.
Fig. 5 is that led lamp among Fig. 2 is along the cut-away view of V-V line.
The specific embodiment
Please see figures.1.and.2 simultaneously, be a preferred embodiment of led lamp of the present invention.Four locking parts 30 that this led lamp comprises a radiator 10, places the light emitting diode module 20 on the radiator 10 and light emitting diode module 20 is locked on radiator 10.Four flexible members 40 be set on the locking part 30 and be folded in radiator 10 and light emitting diode module 20 between.
Please also refer to Fig. 3, radiator 10 comprises a rectangular substrate 11 and the some radiating fins 12 that extended to form by the bottom surface of substrate 11 downwards.Form the groove 13 of four circles on the end face of substrate 11.The degree of depth of groove 13 is less than the thickness of substrate 11.The position, middle of each groove 13 forms a screwed hole 14 that runs through substrate 11 downwards.
Light emitting diode module 20 comprises that one roughly is foursquare circuit board 21 and is matrix form and is installed in some light emitting diodes 22 on the circuit board 21.Corresponding with four screwed holes 14 on the substrate 11, form four through holes 23 on the circuit board 21.
Locking part 30 in the present embodiment is a screw.Each locking part 30 comprises a nut 31 and a screw rod 32 that is extended to form by nut 31 downwards.The periphery of screw rod 32 forms screw thread (not indicating).The diameter of the through hole 23 on the diameter of screw rod 32 and the circuit board 21 is suitable, thereby can pass through hole 23.31 on nut is resisted against on the circuit board 21.
Please refer to Fig. 4 and Fig. 5, during this led lamp assembling, the screw rod 32 of locking part 30 passes the through hole 23 on the light emitting diode module 20.Then flexible member 40 cover is set on the screw rod 32 of locking part 30, is resisted against on the circuit board 21 of light emitting diode module 20 until the nut 31 of locking part 30.At this moment, elastic deformation takes place in flexible member 40, thereby produces elastic force diametrically, and elastic force is fixed together locking part 30 and light emitting diode module 20 whereby.At last, the screw rod 32 of locking part 30 is screwed in the screwed hole 14 of substrate 11 of radiator 10.40 of flexible members are housed in the groove 13 of substrate 11.
Led lamp of the present invention can be fitted together locking part 30 and light emitting diode module 20 in advance by flexible member 40, prevent that locking part 30 from dropping in the process of assembling, thereby make the assembling of light emitting diode module 20 easier from light emitting diode module 20.
