Abstract

The utility model discloses a light-emitting diode (LED) energy-saving lamp with a temperature control switch. The LED energy-saving lamp consists of a lamp shell, a substrate, lamp beads, the temperature control switch and a driving power supply, wherein the temperature control switch is arranged on the LED energy-saving lamp, the lamp shell or the substrate in the lamp shell, or in the lamp shell, and is directly connected in series with an incoming line or an outgoing line of the driving power supply. By the scheme, when the LED lamp has overhigh temperature, the power supply can be disconnected to protect the lamp beads and prolong the service life of the LED lamp, and the LED energy-saving lamp with the temperature control switch is particularly suitable for overheat protection of high-power LED energy-saving lamps.

Description

A kind of LED electricity-saving lamp with temperature detect switch (TDS)

Affiliated technical field

The utility model relates to a kind of LED electricity-saving lamp, especially a kind of LED electricity-saving lamp with temperature detect switch (TDS).

Background technology

At present, the LED electricity-saving lamp comes into vogue, and is of a great variety, and low power LED lamp is many to be made up of through serial or parallel connection the low-power LED lamp pearl; The most promising at present is high-power LED energy-saving lamp, the high-power LED electricity-saving lamp many by single be that 1 watt, 3 watts lamp pearl is formed through serial or parallel connection, employing aluminium base and aluminium, copper radiating subassembly dispel the heat, also useful integrated lamp pearl; Power ratio is bigger, is generally 5 to 100 watts, and maximum can reach more than 100 watts, and the integrated lamp pearl of this type is mainly used in Projecting Lamp; Equally adopt the metal heat sink natural heat dissipation, adopt the metal heat sink natural heat dissipation, though simple in structure; If the power of lamp is excessive, the heating of lamp is just big, and heat radiation is just slow; Possibly cause lamp pearl temperature too high, make the lamp pearl lost of life, also possibly burn the lamp pearl; Low power LED electricity-saving lamp equally requires the temperature can not be high, and no matter the high life-span that has a strong impact on lamp is low-power LED electricity-saving lamp or high-power LED energy-saving lamp at present; Mainly be through natural heat dissipation, do not have overtemperature protection, the life-span of too high sometimes temperature effect LED electricity-saving lamp.

The utility model content

In order to overcome existing LED electricity-saving lamp mainly is through natural heat dissipation; There is not overtemperature protection; The shortcoming in the life-span of too high sometimes temperature effect LED electricity-saving lamp the utility model provides a kind of LED electricity-saving lamp with temperature detect switch (TDS) with head it off, and its good effect is: only need with a temperature detect switch (TDS); Just can carry out overtemperature protection, make the life-span of LED electricity-saving lamp longer the lamp pearl of LED electricity-saving lamp.

The utility model solves the technical scheme that its technical problem adopted:

A kind of LED electricity-saving lamp of the utility model with temperature detect switch (TDS); Form by lamp housing, substrate, lamp pearl, temperature detect switch (TDS), temperature detect switch (TDS) and driving power line, driving power, lamp holder and driving power line; Adopt temperature detect switch (TDS) to be installed on the LED lamp; Can be mounted on the lamp housing, also can be installed in the lamp housing, also can be installed on the substrate in the lamp housing; The method that connects of temperature detect switch (TDS) has three kinds, and a kind of is directly to be connected in the inlet wire of driving power; Second kind is to be connected in the outlet of driving power, and the third connects method is the situation that driving power has two groups of direct current outputs, and two groups of direct current outputs all insert the lamp pearl, and temperature detect switch (TDS) is connected in one group of higher direct current outlet of driving power.

The technical scheme that the utility model adopts will conjunction with figs. elaborate in specific embodiments.

Description of drawings

Be Brief Description Of Drawings below.

Fig. 1 is a kind of LED electricity-saving lamp structural representation with temperature detect switch (TDS) of the utility model.

1. lamp housings among the figure, 2. substrate, 3. lamp pearl, 4. temperature detect switch (TDS), 5. temperature detect switch (TDS) and driving power line, 6. driving power, 7. lamp holder and driving power line.

The specific embodiment

In Fig. 1, we are that example further specifies the utility model to implement a kind of LED electricity-saving lamp with temperature detect switch (TDS):

Lamp housing 1 can be that metal material or plastic or other material are processed among the figure in Fig. 1, can be various shape, and it is modal a kind of only to have drawn among the figure; On lamp housing 1, be connected with lamp holder (the part lamp directly uses line, does not need lamp holder), be connected with translucent cover (partial L ED lamp can not need lampshade) below; In lamp housing 1, substrate 2 is housed, substrate 2 can be an aluminium base; Can be printed panel, have the high-power integrated lamp pearl of part to carry aluminium base, lamp pearl 3 is housed on substrate 2; The lamp pearl can be adopted large, medium and small power modulation pearl, and the most promising at present is to adopt many high-power LED energy-saving lamp pearl series and parallels to form, and also can use integrated lamp pearl; Power confirms that according to concrete needs temperature detect switch (TDS) 4 is installed on the LED lamp by using normally closed bimetallic temperature detect switch (TDS); Multiple peace method is arranged, can be installed on the lamp housing, also can be installed in optional position in the lamp; The optimum position is mounted on the substrate 2, and the method that connects of temperature detect switch (TDS) (4) generally adopts dual mode, and a kind of is directly to be connected in the inlet wire of driving power (6); Another kind connects method and is useful for the situation that driving power (6) has two groups of power supply outputs (can be that one group of power supply is divided into two groups through resistance or voltage-stabiliser tube series connection step-down in fact), and two groups of power supplys are connected on the lamp pearl simultaneously, and temperature detect switch (TDS) (4) is connected on that higher group of voltage.

It is directly to be connected in the inlet wire of driving power (6) that first kind of temperature detect switch (TDS) 4 connects method, and when the LED light temperature was too high, temperature detect switch (TDS) 4 direct deenergizations were protected the lamp pearl; Second kind connects method is to be connected in the direct current outlet of driving power 6, and when substrate 2 temperature were too high, temperature detect switch (TDS) 4 directly broke off the dc source of driving power; The third connects method is that the normally closed node of temperature detect switch (TDS) 4 is connected in higher one group of voltage in two groups of out-put supplies of driving power 6, and when the LED light temperature was higher than the operating temperature of temperature detect switch (TDS) 4, the normally closed node of temperature detect switch (TDS) 4 broke off; Cut off one group of higher power supply, because another group low voltage power supply also inserts in the lamp pearl at ordinary times, at this moment lamp pearl 3 continues luminous; Weak slightly when being light coin normal power supply; But the people to using light influences not quite, and this is best mode, only requires driving power 6 that two groups of out-put supplies will be provided; Have only one group of power supply in fact, can dividing one group through series resistance, voltage-stabiliser tube, to come out also be the same.

After having adopted this programme, the LED electricity-saving lamp is protected when temperature is too high, makes the life-span of LED electricity-saving lamp longer, be particularly suitable for the overtemperature protection of high-power LED energy-saving lamp.
