Mitigate space constriction, is generally used in hotel, family, coffee shop more.
Such as a kind of patent document (application number: LED lamp field disclosed in 201310749913.9), including reflector, set
The bottom cover set the light source assembly in reflector, the radiator at reflector back is set and radiator rear portion is set, it is described
Light source assembly includes substrate and power supply line, further includes general assembly screw, and the screw thread boom end of the general assembly screw sequentially passes through reflection
It is fastened on bottom cover after device, substrate and radiator, since downlight can generate amount of heat during the work time, it is therefore desirable to radiate
Device radiates, however downlight needs to be inserted into the hole held successfully in furred ceiling during installation, the shell of the hole and downlight
Outer diameter matches, therefore the radial dimension of radiator needs to be less than the diameter of hole, this by the heat dissipation performance of limiting heatsink, into
And influence the heat dissipation and service life of downlight.
Summary of the invention
The purpose of the present invention is there is the above problem in view of the prior art, a kind of LED downlight, this LED downlight are proposed
With better heat dissipation performance, guarantee service life.
Object of the invention can be realized by the following technical scheme: a kind of LED downlight, the shell including tubular, shell
Lower end outside circumferentially there is positioning flange, the reflector of taper is fixed in the shell, the upper end of the reflector is solid
Surely there is circular substrate, LED lamp bead is installed on the substrate, the upper end edge of the shell is hinged with two and is symmetrical arranged and works as
Shell can be to lower swing and the pressure arm being pressed on furred ceiling upper side when being inserted into furred ceiling hole, which is characterized in that the base
Several circular lateral heat dissipation pieces are horizontally fixed on plate, which is sequentially distributed up and down, and adjacent two is lateral
There is gap, the lateral heat dissipation on piece circumferentially offers several slots, and the length direction of several slots between cooling fin
Transversely cooling fin is arranged radially, and the slot of several lateral heat dissipation on pieces is aligned one by one, is slided and is inserted in vertically aligned slot
It is connected to vertical cooling fin, and is respectively positioned on the inside on shell place cylindrical surface, the substrate when vertical cooling fin slides into slot
On be additionally provided with the driving member that several vertical cooling fins can be made to stretch out slots when pressure arm is to lower swing.
When downlight is not installed, pressure arm is in vertical state, vertical cooling fin upward and is located in slot, i.e., vertical cooling fin
It is respectively positioned on the inside on cylindrical surface where shell, furred ceiling hole can't be inserted into shell and generates interference, when installation inserts the housing into
Furred ceiling hole, pressure arm to lower swing and can be pressed on furred ceiling upper side during insertion, so that positioning flange is pressed on
On furred ceiling downside, to be positioned to downlight, and it can be made vertically by driving member in the downward swing process of pressure arm
Cooling fin radially slides, and several vertical cooling fins stretch out slot, i.e., vertical cooling fin is stretched out in the top of furred ceiling
Slot, interfere so as to avoid vertical cooling fin and furred ceiling hole and downlight is caused to be difficult to the problem of installing, at this time downlight
