Abstract
The utility model relates to a warning device for radiation failure of an LED lamp. A radiation device is mounted on a substrate of the LED lamp and a temperature sensor is used for measuring temperature of the substrate of the LED lamp. The warning device for radiation failure of the LED lamp can not only give out warning information of radiation failure of the LED lamp, but also control the temperature of the LED lamp to be lower than the light failure temperature of the LED lamp, so that the LED lamp is protected from being damaged, and the service life of the LED lamp is prolonged.
Description
Technical field
The utility model relates to LED lamp technical field, especially a kind of LED lamp heat radiation failure warning device.
Background technology
LED lamp in the market because radiating effect is bad, can't be realized modularity mostly.In order to make the thermal diffusivity of LED lamp improve, need exploitation to make the fin mould of oversize, just with present 100 watts LED street lamp, its radiator just uses the aluminium block more than the 30kg that weighs to solve heat dissipation problem.Out of question even if dispel the heat, but spotlight effect is just very bad.So following LED lamp will be modular trend.
The LED lamp is because thermal diffusivity is bad, and temperature usually is higher than the light decay temperature of itself, so the useful life of LED lamp is generally shorter.
The utility model content
The technical problems to be solved in the utility model is: in order to solve the problem of mentioning in the above-mentioned background technology, the utility model provides a kind of LED lamp heat radiation failure warning device that can in time allow the heat radiation situation that the light fixture administrative staff learn light fixture.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED lamp heat radiation failure warning device, and on the substrate of LED lamp, install and be provided with heat abstractor, detect the substrate temperature of LED lamp with temperature sensor.
Further: the heat abstractor that is mounted on the LED lamp substrate connects as one structure by two or more radiators by prominent bar with the corresponding link slot of prominent bar.
Further: radiator comprises arc, the extrados of arc extends outward at least two fin spaced apart, one end face of arc is provided with link slot along the longitudinal direction, the other end of arc is provided with along the longitudinal direction and is connected with prominent bar, longitudinal direction on the arc is provided with at least one heat pipe installing hole, one side of the intrados of radiator is provided with heat-conducting piece, some heat pipe mounting grooves are set on the heat-conducting piece, one end of super heat-conductive pipe is plugged in the heat pipe mounting groove on the heat-conducting piece, and the other end of super heat-conductive pipe is plugged in the heat pipe installing hole on the radiator.
The beneficial effects of the utility model: LED lamp heat radiation failure warning device of the present utility model is when breaking down; light the mode of LED lamp with interruption and warn the LED lamp trimmer; be very easy to be found by road lamp management person; thereby can make the LED lamp that the heat radiation fault occurs obtain on-call maintenance; this device not only can send failure warning information; and the temperature that can control the LED lamp is lower than its light decay temperature, and protection LED street lamp is not damaged, and promptly prolongs the useful life of LED lamp.
Simultaneously, the fin on the LED heat sink for lamp adopts modularized design, makes the unification of radiator mould, needn't can save the mould development expense for the LED lamp exploitation radiator mould of every kind of different capacity; Radiator adopts the arc design, can dwindle radiator on the one hand and take sky and ask, also helps distributing of heat; Thick, the top thin in fin bottom can further increase the distance between the adjacent fin, accelerates distributing of heat.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of radiator;
Fig. 3 is the structural representation of heat-conducting piece.
Among the figure 1, radiator, 11, arc, 12, fin, 13, link slot, 14, prominent bar, 15, the heat pipe installing hole, 2, heat-conducting piece, 21, the heat pipe mounting groove, 3, super heat-conductive pipe.
Embodiment
As Fig. 1, Fig. 2 and LED lamp heat radiation failure warning device shown in Figure 3, on the substrate of LED lamp, install and be provided with heat abstractor, detect the substrate temperature of LED lamp with temperature sensor.
The heat abstractor that is mounted on the LED lamp substrate connects as one structure by two or more radiators 1 by prominent bar 14 with prominent bar 14 corresponding link slots 13.
Radiator 1 comprises arc 11, the extrados of arc 11 extends outward at least two fin spaced apart 12, one end face of arc 11 is provided with link slot 13 along the longitudinal direction, the other end of arc 11 is provided with along the longitudinal direction and is connected with prominent bar 14, longitudinal direction on the arc 11 is provided with at least one heat pipe installing hole 15, one side of the intrados of radiator 1 is provided with heat-conducting piece 2, some heat pipe mounting grooves 21 are set on the heat-conducting piece 2, one end of super heat-conductive pipe 3 is plugged in the heat pipe mounting groove 21 on the heat-conducting piece 2, and the other end of super heat-conductive pipe 3 is plugged in the heat pipe installing hole 15 on the radiator 1.
The defencive function that above-mentioned LED lamp heat radiation failure warning device is realized is as follows:
With the substrate temperature of temperature sensor detection LED lamp, control circuit compares the ceiling temperature of detected substrate temperature of temperature sensor and LED lamp, when substrate temperature is higher than the ceiling temperature of LED lamp, will cut off the power supply of LED lamp automatically; When substrate temperature is lower than the ceiling temperature of LED lamp, will connect the power supply of LED lamp; When substrate temperature rises when being higher than the ceiling temperature of LED lamp once more, cut off the power supply of LED lamp once more; So repeatedly, utilize the interruption of LED lamp to light this LED lamp appearance heat radiation fault of caution.
On the other hand, because when substrate temperature is higher than ceiling temperature (ceiling temperature is less than the light decay temperature of LED lamp), just cut off the power supply of LED lamp, so the temperature that its can control simultaneously the LED lamp can not be higher than the light decay temperature of LED lamp, and then prolong the useful life of LED lamp.
