Description of the Invention: [Technical Field] The present invention relates to a type of lamp, and more particularly to a lighting module having high heat dissipation effect and high illumination power. [Prior Art] Light Emitting Diode (LED), or High Light Emitting Diode (HLED) has the characteristics of small current and low power, so it has been Widely used in a variety of luminaires, such as projection lamps. Although the power consumption of a single light-emitting diode is extremely low, the heat generated by the light-emitting process will gradually accumulate and cause a thermal effect' and affect its luminous efficacy and service life. When the brightness is increased to increase the brightness of the light-emitting diode The lighting power will make the impact of the thermal effect more serious. Therefore, the light-emitting diode light source requires extremely high heat emission. In contrast, the heat dissipation efficiency is also a limiting condition for improving the illumination brightness of the light-emitting diode lamp.

Affecting the function of the illuminating lamp 1 'make the conventional illuminating light' have the disadvantage of being heat-dissipating: poor and unable to further improve the lighting power and brightness. 2. In the process of illuminating the illuminator i, in addition to the heat generated by the illuminating diode 12, the circuit board 132 generates heat, and the illuminating diode 12_ can be thermally conductive. Divergence, since the lamp holder 131 is mostly made of glue material, the heat generated during the power supply process of the circuit board 132 is less likely to be derived, and the long-term use will also affect the function and the life of the circuit board 132. The heat dissipation function is not complete enough, and it is easy to affect the overall performance and the lack of service life. 3. The circuit 柘n 〇 of the illuminating lamp 1 - the electric sill plate 132 is mounted in the socket 131' is usually mounted in a sturdy manner as shown in Fig. 1, so that the circuit board 132 is in contact with the socket 131 The small area can not be borrowed (4) to guide the effective scattered track, and it also has the disadvantage that the heat sink is good and its operation effect (4).

The power supply assembly 52 has a circuit board 521 electrically connected to the two wires 51 and contacting the base 321 of the socket 32, and two electrically connected to the circuit board 11 1307752 521 and away from the light-emitting element 4 The insertion terminal 522 is electrically connected to an external power (not shown), and a receiving slot 322 that fits the socket 32 is wrapped around the circuit board 521 and is available for the second insertion.

During the illumination of the light-emitting element 4, the circuit board 521 and the light-emitting element 4 both have a portion of electrical energy to work as thermal energy, and the generated thermal energy is continuously accumulated on the circuit board 521 and the light-emitting element 4 to be in a high temperature state. The performance of the light-emitting element 4 and the circuit board 521 will be affected. Therefore, the effective and efficient heat dissipation design of the present invention can avoid the adverse effects of the thermal effect and maintain the working efficiency of the overall lighting module 2. The heat energy generated by the light-emitting element 4 can be transmitted to the lamp housing 31 through the base material 41, and the heat dissipation rib 314 connected to the main housing 311 increases the heat dissipation area of the lamp housing 31. Accelerating the conduction and divergence of heat, and in addition, since the heat dissipation ribs 314 are designed to have a width change, the heat dissipation area of the narrow end portion 315 is smaller than the heat dissipation area of the wide end portion 316, and the corresponding heat dissipation amount is also Relatively low, forming a distribution state along the narrow end portion 315 through the rib portion 317 to the wide end portion 316 with a gradual decrease in temperature. The temperature difference distribution caused by such a design can be at the narrow end portion 315 Thermal convection is formed between the wide ends 316 to facilitate heat dissipation. The circuit board 521 can also be transmitted to the lamp holder 32 through the thermal conductive adhesive, and the heat dissipation fins 324 of the body 321 can be added to the heat dissipation fins to accelerate the heat dissipation efficiency. The cost of the circuit board 521 is too high to affect its performance. It is to be noted that the present invention can form a convection by the design of the width variation of the heat dissipation ribs 314 to increase the heat dissipation speed in a stepwise manner. Therefore, it is possible to use a hair with a higher power. 7L piece 4, for example, the general heat dissipation 13 1307752 can only be used with the light-emitting element 4 of about 3W power. If the light-emitting element 4 with higher power is used, the heat dissipation efficiency may be poor, and the temperature is too high, resulting in the light-emitting 7C piece. 4 burned, and the present invention can use the illuminating element 功4 of the work #5W by the design which can induce the convection to further increase the heat dissipation efficiency, so that the illumination brightness can be further increased to increase the application range of the lighting module 2.

In addition, the first and second auxiliary heat dissipation layers 33 and 34 formed on the lamp housing 31 and the lamp holder 以 with boron nitride as a raw material can further increase the total heat dissipation area, thereby further improving the heat dissipation efficiency.

Referring to FIG. 8 , a heat dissipating lamp used in a first preferred embodiment of the present invention is in the form of a type 31. The difference between the second preferred embodiment and the first preferred embodiment is mainly in the design of the lamp housing 31. Other structures and components are the same as those of the preferred embodiment, so that only the lamp cap 31 of the second preferred embodiment will be described. The heat sink casing 31 is also made of a heat-conductive metal material. An inner body 36, an outer casing 37 spaced from the inner casing 36, and at least one intermediate casing 38 disposed between the inner and outer casings 36, 37, in the preferred embodiment. The inner and outer casings %, 37 and the intermediate casing 38 are all made of an aluminum extruded profile. The inner casing 30 includes an inner bottom wall 361' and an inner surrounding wall 362 extending obliquely upward from the periphery of the inner bottom wall 361. The outer casing 37 includes an outer bottom wall 371 spaced from the inner bottom wall 361, and an outer surrounding wall 372 extending obliquely upward from the outer peripheral wall 371 and spaced from the inner surrounding wall 362. The intermediate housing 38 includes an intermediate bottom wall 381 that is in contact with the inner bottom wall 361 and the outer bottom wall 371, and an obliquely upwardly extending from the periphery of the intermediate bottom wall 38j. An intermediate surrounding wall 382 is spaced from the inner and outer surrounding walls 362, 372, respectively. In the second preferred embodiment, the lamp housing 31 includes a plurality of intermediate housings 38 disposed between the inner and outer housings 36, 37, and the intermediate bottom wall 381 of the intermediate housings 38 is They are in close contact with each other, and the intermediate surrounding wall 382 is disposed at intervals, but the number of the intermediate casings 38 should not be limited thereby, and only one intermediate casing 38, or two or three Even three or more intermediate housings 38 can achieve the purpose of effectively increasing the heat dissipation area. In addition, the inner surrounding wall 362 of the inner casing 36, the intermediate surrounding wall 382 of the intermediate casing 38, and the outer surrounding wall 372 of the outer casing 37 are of a progressively increasing type from the inside to the outside. Further expanding the area gaps around the walls 362, 382, and 372 makes it easier to form a distribution pattern having a temperature difference. When the light-emitting element 4 (see FIG. 4) is attached to the inner bottom wall 361 of the inner casing by the heat-conductive adhesive, the heat generated by the illumination process can also pass through the inner bottom wall 361, the intermediate bottom wall 381, and the outer portion. The bottom wall 371 conducts and respectively dissipates heat to the inner surrounding wall 362, the intermediate surrounding wall 382 and the outer surrounding wall 372, and the design of the surrounding walls 362, 382, 372 arranged at intervals is also increased. The total heat dissipating area of the shell 31 is different from the heat dissipating area of the inner surrounding wall 362, the intermediate surrounding wall 382 and the outer surrounding wall 372, and a temperature distribution pattern is formed between the surrounding I 362, 382, and 372. Thereby, the heat convection formed by the temperature difference can be further accelerated to further accelerate the heat dissipation efficiency of the lamp envelope 31 to achieve the same heat effect as the first preferred embodiment. Similarly, a thermal conductive coating made of boron nitride may be sprayed on the outer surfaces of the inner casing 36, the intermediate casing 38 and the outer casing 15 1307752 37 to form the first auxiliary heat dissipation layer 33, and further The heat dissipation effect of the lamp housing 31 is improved. In summary, the lighting module 2 having the heat-dissipating lamp housing of the present invention can achieve the following functions and advantages, so that the object of the present invention can be achieved: 1. In addition to manufacturing the lamp housing 31 with a metal material that is easy to dissipate heat, The heat dissipating ribs 314 respectively disposed in the main casing 311 of the lamp housing 31, or the surrounding walls 362, 382, 372 and the like having a plurality of different calibers and spaced apart, greatly increase the heat dissipating area of the lamp housing 31. The light-emitting element 4 is less susceptible to thermal effects and has the advantage of better heat dissipation. 2. Cooperating with the variation of the width and the heat dissipation area of the narrow end portion 315, the rib portion 317 and the wide end portion 316 of the heat dissipation rib 314, resulting in a temperature distribution pattern with temperature difference, which is favorable for forming heat convection to further accelerate heat. The political power, even if the power value of the light-emitting element 4 used is increased, does not affect its luminous efficiency, so that the present invention can increase the illumination brightness and the application range by increasing the illumination power of the light-emitting element 4. 1. The inner casing 36, the intermediate casing 38 and the outer casing 37 are combined to have different heat dissipation areas, and the inner surrounding wall 382 and the outer surrounding wall 372 have different heat dissipation areas. The temperature distribution formed by the temperature difference during the illumination of 彳4 is also advantageous for causing thermal convection to further accelerate heat dissipation, and can increase the illumination power of the light-emitting element 4 to increase the illumination intensity of the single-light-emitting element 4, and further increase the illumination. The scope of application of module 2. 4. In addition to the heat dissipation design of the light-emitting element 4, the lamp holder 32 of the circuit 161307752 is also used with a material with better heat dissipation effect, and the heat dissipation fin 324 is further added to further increase the heat dissipation area to accelerate heat dissipation. The circuit board 521 is also less susceptible to thermal effects, so that the present invention can increase the overall performance and service life by providing a more complete heat dissipation design. 5. The first and second auxiliary heat dissipation layers 33, 34 additionally increase the heat dissipation area of the lamp housing 31 and the lamp holder 32, which is more conducive to heat dissipation, and the invention can also be effectively and quickly The heat dissipation can achieve the effect of increasing the overall efficiency of σ and prolonging the service life. Referring to FIG. 3, FIG. 7, and FIG. 8, the following experimental test results supplement the description of the heat dissipation lamp housing 31 by the heat dissipation ribs 314, or the inner casing 36, the intermediate casing 38 and the outer casing 37 are layer-by-layer. The effects achieved by the overlapping design, Table-1 is to install the LEDs to the lamp housing A, the lamp housing B1, the lamp housing B2, and the lamp housing C at room temperature (ambient temperature 20 ° C). And continuously energizing the illuminating element to provide illumination. After 3 hours, the result of measuring the luminous flux of the lamp housing A, the lamp housing B1, the lamp housing B2 and the lamp housing C and the lamp housing temperature, wherein the lamp housing A ( 3) is a conventional lamp-shaped lamp housing 11 which is not provided with heat dissipation ribs or heat dissipation fins. Both the lamp housing B1 and the lamp housing B2 (see FIG. 7) are the lamp housing 31 provided with the heat dissipation rib 314 of the present invention. C (see FIG. 8) is a lamp housing 31 which is annularly combined with the inner casing 36, the intermediate casing 38 and the outer casing 37, wherein the power of the LEDs of the lamp housing A and the lamp housing B1 are both For 3W, the power of the lamp housing B2 and the LED matched with the lamp housing C is 5W. It should be added that there are two types of LEDs used in this test. Lamp housing A, lamp housing B1 and lamp housing B2 are matched with LEDs made of gallium arsenide crystal grains. The LEDs are made of 130 砷 矽 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 17 The gallium grain is manufactured by a high degree, but the heat dissipation temperature is not directly related to the grain type, mainly related to the power of the LED used. The higher the power, the higher the heat and temperature, so although different grains are LEDs produced will exhibit different illumination levels, but the heat dissipation of different types of lamp housings can still be compared directly with LEDs of the same power.

Note (1), y, ? The temperature measured at the narrow end portion 315, the wide end portion 316, and the like of 314 is not shown.

The temperature of the lamp housing 31 measured in the inner casing Zhao 36 and the two from the inside to the outside; the casing 38 and the outer casing 37 are measured. According to the results of Table 1, when using the same power (3W) LED, the luminous flux of the lamp housing B1 will be slightly higher than the luminous flux of the lamp housing A, and the temperature measured at different positions of the lamp housing B1 is smaller than the lamp housing A. The temperature indicates that the design of the present invention (4) does increase the heat dissipation efficiency. In addition, the temperature distribution of the lamp envelope A is a uniform distribution without a temperature difference (ie, the degree of the enthalpy at any position on the housing U1 of FIG. The average temperature distribution), the temperature of the lamp housing is a distribution pattern with a temperature difference 'showing that the heat dissipation ribs 314 @width change can cause the cultivating cloth to easily cause heat convection, so as to further enhance the heat dissipation effect, and then 18 1307752 * Enables LEDs to perform better, while relatively higher luminous flux. In addition, according to the test data of the lamp housing B2 and the lamp housing c, it can be seen that the lamp housing 31 having the heat dissipation rib 314' or the multilayer housing 36, 38, 37 can withstand the power of 5W LED, and can be fast. In the heat dissipation, the lamp housing 32 has a temperature value lower than that of the lamp housing A except that the temperature of the base wall portion 318 is slightly higher than the temperature of the lamp housing a, and the lamp housing c is the inner casing 36. The intermediate casing 38 and the outer casing 37 are layered, so that the total heat dissipation table φ area is larger than that of the lamp housing B2, thereby exhibiting lower temperature and better heat dissipation performance, and at the same time, the lamp housing B2 and The lamp housing c is also a temperature distribution pattern that maintains a temperature difference, and it is shown that the heat dissipation lamp housing 31 of the present invention can increase the heat dissipation area and cause heat convection by the heat dissipation ribs 314' or the housings 36, 37, 38. It can achieve the function of effectively dissipating heat and the high-power light-emitting element 4. It is worth noting that although the same power [ED can usually exhibit the same illumination brightness (light flux), when combined with different lamp housings, the heat dissipation effect of different lamps φ double is different, if there is better heat efficiency The effect is to avoid excessive heat accumulation in the LED and affect its luminous efficiency. Therefore, although the LED power and type of the lamp housing A and the lamp housing Bi are the same, since the lamp housing B1 has better heat dissipation effect, The luminous flux slightly higher than the lamp envelope A can be measured in the lamp housing bi. The above is only the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, that is, the simple equivalent change of the scope of the invention and the description of the invention. Modifications are still within the scope of the invention.
