Further, test board is provided with multiple slot, and slot is connected with power connection.The LED charactron that slot on test board can be tested as required is adjusted, and motility is good.
Further, test board bottom surface is provided with support means, it is possible to play a supporting role the test board carrying out thermal ageing test, prevents plate body from bending because working long hours.
Further, outside air inlet, it is provided with the first air door, outside air outlet, is provided with the second air door.First air door and the second air door switch the most automatically, make test box have faster firing rate and more preferable insulating power.
Further, photographic head is high temperature resistant camera head.Because test environment is harsh, high temperature resistant camera head is used to increase the service life, it is ensured that the efficiency to element testing.
This utility model compared with prior art has the advantage that reasonable in design, compares traditional test mode, uses both sides heater circulating-heating simultaneously, and the efficiency of heating surface is good, it is possible to test many groups multiclass LED charactron simultaneously, test volume is big；Simple to operate, putting and retracting of another batch of element can be carried out while testing a collection of element, time-consuming；Carry out Real Time Observation while can be implemented in testing element, contribute to searching problem.

Detailed description of the invention
The utility model is described in further detail below in conjunction with the accompanying drawings and by embodiment.
Embodiment.
See Fig. 1-Fig. 7, this utility model includes casing 1 and test board 2, casing 1 is provided with air channel 11 in two side, temperature sensor 12 it is provided with in casing, guidance panel 13 it is provided with outside casing, being additionally provided with liquid crystal display 14 outside casing, be provided with photographic head 15 in casing, photographic head 15 is connected with liquid crystal display 14；Lower end, casing 1 both sides is provided with heater 3 and blower fan 4, and heater 3 is connected with air channel 11, and blower fan 4 is arranged on heater 3 side；Power supply draw-in groove 16 arranged vertically it is provided with in casing 1, casing 1 inwall of power supply draw-in groove 16 both sides is provided with air inlet 17, casing 1 top is provided with air outlet 18, and inside casing 1, top is provided with circulating air opening 19, and air inlet 17, air outlet 18 and circulating air opening 19 are connected with air channel 11 respectively.Test board 2 rear end is provided with power connection 21, and power connection 21 is connected with power supply draw-in groove 16.Can be configured required test temperature and testing time at guidance panel 13, casing 1 both sides are equipped with heater 3, and heating process is fast, compares existing apparatus, by air channel circulating-heating evenly.Monitoring signal is transmitted to liquid crystal display 14 by photographic head 15, it is possible to monitor test process in real time.
Further, test board 2 is provided with multiple slot 22, and slot 22 is connected with power connection 21.The LED charactron that slot 22 on test board 2 can be tested as required is adjusted, and motility is good.
Further, test board 2 bottom surface is provided with support means 23, it is possible to play a supporting role the test board carrying out thermal ageing test, prevents plate body from bending because working long hours.
