Description

A kind of LED lamp panel possessed from radiator structure

Technical field

This utility model relates to light fixture cooling mechanism technical field, particularly relates to a kind of LED possessed from radiator structure Plate.

Background technology

LED is a kind of new type light source, has the high and low power consumption of brightness, life-span length, starts fast, power is little, without stroboscopic, no Easily producing advantages such as regarding visual fatigue, be described as the light source revolution of 21 century, utilization field relates to mobile phone, desk lamp, household electrical appliances Etc. daily household electrical appliances and machinery production aspect.The basic structure of LED is one piece of electroluminescent chip of semiconductor material, uses elargol Or latex solidified is on support, then connects chip and circuit board with silver wire or gold thread, then surrounding epoxy sealing (is protected Protect internal core), shell is finally installed.Chip of semiconductor material i.e. LED light emitting diode, by containing gallium (Ga), arsenic (As), phosphorus (P), the compound of nitrogen (N) etc. is made.It is the one of semiconductor diode, electric energy can be changed into luminous energy.

LED due to its principle of luminosity so there being following point: because its heating is concentrated, and the poor heat radiation of encapsulant, The temperature causing LED is too high so that LED chip light decay is serious, shortens its service life；And its luminous body is little, for reaching To certain brightness, multiple LED light emitting diode need to be used so that LED is in use brought rapidly up, speed-up chip light Decline.Heat radiation, is a big problem facing of current LED lamp.

The heat radiation of LED is very passive now, uses the heat abstractor being connected with LED by wind-cooling heat dissipating method handle In LED LED chip be combined generation heat derive go.The method using passive wind-cooling heat dissipating, causes heat abstractor excessive, effect Rate is relatively low；Employing active air cooling dispels the heat, although heat abstractor is less, efficiency is higher than passive wind-cooling heat dissipating, but heat abstractor is from putting Heat, is connected the temperature that still can improve LED, speed-up chip light decay with LED.

Therefore, we are badly in need of designing a kind of LED lamp panel possessing radiator structure and solve the problems referred to above.
