Description

A kind of LED projector lamp

Technical field

The utility model belongs to lighting technical field, and in particular to a kind of LED projector lamp.

Background technique

Projecting Lamp is the lamps and lanterns of the projecting environment of illumination on specified face to be illuminated.In general, it can aim at any direction, And has the structure that climate condition does not influence.It is mainly used for large area operation field mine, contour of building (such as stadium, grade separation Bridge, monument, park and flower bed etc.)；Therefore, the large area lighting lamps and lanterns of nearly all outdoor application can all regard Projecting Lamp as. LED has the advantages of energy conservation and environmental protection, long service life, therefore LED projector lamp using LED as light source is just more and more instead of biography The Projecting Lamp of system.Projecting Lamp at work due to power the problem of its calorific value be also it is biggish, in order to guarantee that Projecting Lamp can The need of work leaned on radiates to it, and its harsh environments (working environment of Projecting Lamp is often located outside, in order to Guarantee to set that light lamp does not make moist or the entrance of foreign matter is substantially using sealed), therefore LED projector lamp can only select traditional passive type Heat dissipation, i.e., the heat generated when being worked with improving LED light source by adding radiating fin in the aluminum enclosure of Projecting Lamp dissipate Hair.That is, the LED substrate as light source fits with shell, the heat that LED lamp bead generates when working is transmitted to light projector by substrate It on radiating fin on the shell of lamp and on shell and radiates, at this time the contact point of the shell of Projecting Lamp and LED light source Temperature highest, and carry out heat transfer around as central point.But the power of the LED lamp bead as light source often as high as counts Ten watts or hundreds of watts, the heat that when work generates be it is huge, be often by the speed that shell carries out heat transfer it is inadequate, Especially when background ambient temperature is relatively high (such as summer), therefore LED light source can be prevented to increase LED light source from sufficiently radiating Light decay rate, and thus reduce LED projector lamp service life, while also improving the use cost of Projecting Lamp.

Utility model content

In view of this, the utility model aim is to provide, one kind is structurally reasonable, and heat dissipation is abundant and reduces the LED of use cost Projecting Lamp.

In order to solve the above-mentioned technical problem, the technical solution of the utility model is:

A kind of LED projector lamp, including shell and light source assembly, the appearance of the shell are provided with multiple radiating fins, institute State that radiating fin is integrally formed with shell, the another side in the shell relative to radiating fin is provided with one or in interval The a plurality of groove of arrangement, be provided in the groove with its mutually matched heat pipe, the heat pipe is fixedly connected with the casing, described Light source assembly is fitted closely and is immobilized in the shell, and be located at the groove in one or more heat pipe all with light source phase component It offsets.Since heat pipe has outstanding thermally conductive energy and heat-transfer rate, the heat generated when light source assembly can be worked It is oriented to its far-end rapidly along heat pipe and is distributed by the radiating fin on shell, that is, effectively increase the hot transmitting of shell Distributing for speed and heat, avoids the portion temperature being in contact on shell with light source assembly higher, and the peripheral temperature of shell The even phenomenon of relatively low conduction inequality.

Preferably, the groove extends along the length or width direction of the shell, heat pipe is helped by heat to shell Far-end transmitted.

Preferably, the light source assembly includes substrate, LED lamp bead and rectification circuit, the LED lamp bead and rectification circuit Be electrically connected with substrate, the substrate is fixedly connected with the casing, and be located at the groove in one or more heat pipe all with institute Substrate is stated to fit.

Preferably, the contact surface of the heat pipe and the substrate is arranged in plane, facilitate generation when LED lamp bead work Heat by being transmitted substantially to heat pipe.

Preferably, it further includes reflector that packet, which states light source assembly, the reflector cover is closed in the LED lamp bead；It helps In make LED lamp bead issue light after reflection can direction as required propagated, i.e., raising light utilization efficiency.

Preferably, further including lampshade and sealing ring, the lampshade is solidly connected with the shell, and the sealing ring is located at institute It states between lampshade and shell；The sealing performance for helping to improve Projecting Lamp avoids the internal wetted of Projecting Lamp.

Preferably, further include adjusting bracket, the adjusting bracket is in U-shape setting, and the end of adjusting bracket and shell Rotation connection facilitates the irradiating angle for adjusting or changing Projecting Lamp.

The utility model has the technical effect that following aspect: due to being provided with and light source assembly phase in shell The heat pipe mutually cooperated, heat pipe have it is outstanding it is thermally conductive can and heat-transfer rate, therefore when light source assembly can be worked, generates Heat is oriented to rapidly its far-end along heat pipe and is distributed by the radiating fin on shell, from without shell with The excessively high phenomenon of the local temperature that light source assembly is in contact, therefore the radiating efficiency of shell is effectively increased, therefore avoid LED Light source cannot sufficiently radiate and increase light decay rate, and reduce the service life of Projecting Lamp, while also reduce making for Projecting Lamp Use cost.
