Description

LED light

Technical field

The utility model relates to lighting source fields, more particularly, to a kind of LED light with great heat radiation effect.

Background technique

LED light gradually replaces the market of conventional lights with its beneficial performance such as low, luminous efficiency is high, long service life that consume energy Status, but LED light has that maximum is exactly the heating problem of LED lamp, if the high temperature of fever is unable to disperse in time, The service life of LED light will be will have a direct impact on, therefore heat dissipation problem the problem of LED lamp industry compares emphasis always.It is existing Scheme generally by the aperture on lamp housing, allow inner air and outer air can convection current achieve the purpose that heat dissipation.But aperture is easy to make Dust enters, and heat dissipation effect can drastically reduce after dust stratification, and ash disposal is more difficult, this exterior open cell is excessive, and to reduce lamp housing strong Degree, the too small then heat dissipation effect of aperture are undesirable.

Summary of the invention

The utility model mainly solves radiator structure ash disposal hardly possible present in the prior art, influence heat dissipation effect is used for a long time The technical issues of fruit, casing rigidity and heat dissipation cannot be considered in terms of provides a kind of good heat dissipation effect, dust stratification easy to clean, casing rigidity not Impacted LED light.

What the utility model was mainly addressed by following technical proposals in view of the above technical problems: a kind of LED light, If the upper housing is hemispherical Shell including LED lamp panel, upper housing, lower case, interconnecting piece, interior heat-conducting piece and dry plate cooling fin, on The upper end of the lower end connection lower case of shell, the lower end of lower case are connect with interconnecting piece, and cooling fin is annular sheet metal, cooling fin Horizontal card is in close contact on the outside of lower case and with interior heat-conducting piece, and LED lamp panel back and interior heat-conducting piece are in close contact.

In the present solution, cooling fin is mounted on hull outside, the heat that LED lamp panel generates is transmitted to heat dissipation by interior heat-conducting piece On piece, cooling fin dissipate the heat to the air.Since cooling fin is in hull outside, heat dissipation effect is much larger than the aperture on shell Mode, and dust stratification is also easy to remove, without dismantling shell.Lamps and lanterns are generally mounted on roof, the air-flow stream of surrounding Dynamic direction is usually vertical with installation direction, and the cooling fin of this programme is to be horizontally mounted, parallel with air current flow direction, it is easier to Heat distributes.

Preferably, the interior heat-conducting piece includes heat-conducting substrate and thermally conductive inner casing, it is raised platforms in the middle part of heat-conducting substrate, leads Hot substrate edge flips up, and LED lamp panel is mounted in raised platforms, and heat-conducting substrate is installed on thermally conductive inner casing, thermally conductive inner casing It is mounted on the inside of lower case and is connect with cooling fin.

Heat-conducting substrate edge flips up, and can directly be caught in thermally conductive inner casing ensures that substrate and inner casing are in close contact, tool There is good heat-conducting effect.The raised platforms at middle part are concordant with the upper end of lower case as mounting surface or are substantially flush, compared to Sagging structure is more convenient for the installation and removal of LED lamp panel.

Preferably, including elastic contact chip on the inside of the cooling fin, lower shell surface is provided with to match with elastic contact chip The mounting hole of conjunction, elastic contact chip are inserted into mounting hole and are in close contact with thermally conductive inner casing.

Mounting hole is horizontal narrow slit, and thickness and width cooperates with elastic contact chip, so that after cooling fin installs Dust is not had to enter in lower case.

Preferably, the LED lamp panel is mounted on heat-conducting substrate by heat conductive silica gel.

Heat conductive silica gel transmits heat between LED lamp panel and heat-conducting substrate more rapidly.

Preferably, in the LED lamp panel the ratio between LED lamp bead quantity and resistance be 2:1, the parallel connection of every two LED lamp bead with It connects afterwards with a resistance and is then attached to positive pole and power cathode.

Traditional LED lamp panel, each lamp bead are connected with a resistance, this programme by two lamp beads it is in parallel after with an electricity Resistance series connection, reduces lamp plate area, reduces material cost, reduces manually installed cost.

The utility model bring beneficial effect is good heat dissipation effect, dust stratification easy-clear, can guarantee casing rigidity, drop Low cost.
